Addressing multilevel barriers to clinical trial participation among Black and White men with prostate cancer through the PACCT study.

BACKGROUND: Cancer clinical trial participation is low and inequitable. Partnering Around Cancer Clinical Trials (PACCT) addressed systemic and interpersonal barriers through an observational study of eligibility and an intervention to improve patient-physician communication and trial invitation rates. METHODS: Physicians at two comprehensive cancer centers and Black and White men with prostate cancer participated. Patients were followed for 2 years to determine whether they became potentially eligible for an available therapeutic trial. Potentially eligible patients were randomized to receive a trials-focused Question Prompt List or usual care. Patient-physician interactions were video-recorded. Outcomes included communication quality and trial invitation rates. Descriptive analyses assessed associations between sociodemographic characteristics and eligibility and effects of the intervention on outcomes. RESULTS: Only 44 (22.1%) of participating patients (n = 199) became potentially eligible for an available clinical trial. Patients with higher incomes were more often eligible (>$80,000 vs. <$40,000, adjusted OR = 6.06 [SD, 1.97]; $40,000-$79,000 vs. <$40,000, adjusted OR = 4.40 [SD, 1.81]). Among eligible patients randomized to the intervention (n = 19) or usual care (n = 25), Black patients randomized to the intervention reported participating more actively than usual care patients, while White intervention patients reported participating less actively (difference, 0.41 vs. -0.34). Intervention patients received more trial invitations than usual care patients (73.7% vs. 60.0%); this effect was greater for Black (80.0% vs. 30.0%) than White patients (80.0% vs. 66.7%). CONCLUSIONS: Findings suggest the greatest enrollment barrier is eligibility for an available trial, but a communication intervention can improve communication quality and trial invitation rates, especially for eligible Black patients.

Culturally targeted message framing and colorectal cancer screening preferences among African Americans.

OBJECTIVE: The current study investigated whether culturally targeted message frames alter preferences for specific colorectal cancer (CRC) screening modalities among African Americans. METHOD: African Americans who were eligible for CRC screening (N = 457) viewed a video about CRC risks, prevention, and recommended screening options. Participants then received a gain or loss-framed message about screening, with half of participants viewing an additional culturally targeted message about overcoming disparities in CRC through screening. Participants reported their desired thoroughness in CRC screening and preferences for being screened using colonoscopy, sigmoidoscopy, or stool-based fecal immunochemical testing. RESULTS: Relative to gain-framing, loss-framed messaging enhanced desired thoroughness in CRC screening. Targeted loss-framing enhanced preferences for colonoscopy and decreased preferences for stool-based FIT screening. CONCLUSIONS: Findings demonstrate that message framing and culturally targeted messaging can impact CRC screening preferences. Altering preferences may carry implications for reducing CRC screening disparities among African Americans. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Nonverbal Synchrony: An Indicator of Clinical Communication Quality in Racially-Concordant and Racially-Discordant Oncology Interactions.

OBJECTIVES: The aim of this cross-sectional study was to apply a novel software to measure and compare levels of nonverbal synchrony, as a potential indicator of communication quality, in video recordings of racially-concordant and racially-discordant oncology interactions. Predictions include that the levels of nonverbal synchrony will be greater during racially-concordant interactions than racially-discordant interactions, and that levels of nonverbal synchrony will be associated with traditional measures of communication quality in both racially-concordant and racially-discordant interactions. DESIGN: This is a secondary observational analysis of video-recorded oncology treatment discussions collected from 2 previous studies. SETTING: Two National Cancer Institute-designated Comprehensive Cancer Centers and another large urban cancer center. PARTICIPANTS: Participants from Study 1 include 161 White patients with cancer and 11 White medical oncologists. Participants from Study 2 include 66 Black/African-American patients with cancer and 17 non-Black medical oncologists. In both studies inclusion criteria for patients was a recent cancer diagnosis; in Study 2 inclusion criteria was identifying as Black/African American. MAIN OUTCOME MEASURES: Nonverbal synchrony and communication quality. RESULTS: Greater levels of nonverbal synchrony were observed in racially-discordant interactions than in racially-concordant interactions. Levels of nonverbal synchrony were associated with indicators of communication quality, and these associations were more consistently found in racially-discordant interactions. CONCLUSION: This study advances clinical communication and disparities research by successfully applying a novel approach capturing the unconscious nature of communication, and revealing differences in communication in racially-discordant and racially-concordant oncology interactions. This study highlights the need for further exploration of nonverbal aspects relevant to patient-physician interactions.

Development and pilot test of a physician-focused cancer clinical trials communication training intervention.

Objective: We describe the development and pilot test of a physician-focused, web-based training module designed to improve physician communication related to clinical trials in a diverse cancer patient population. Methods: Researchers and stakeholders developed the training module, which included a video explaining patient-centered communication strategies for discussing trials, and re-enactments of actual clinical interactions. For the pilot test, the module was provided to physician participants in the Partnering Around Cancer Clinical Trials (PACCT) trial at two major urban cancer centers. Questionnaires assessed change in beliefs, behavioral attitudes, knowledge and comfort; and perceptions of the module. Results: Nineteen physicians participated in the pilot test. Most were experienced in discussing trials. Assessments of change were mixed regarding beliefs; they showed marginal improvement in attitudes, and significant improvement in knowledge, but no change in comfort. Feedback on the module was favorable. Conclusions: This stakeholder-developed physician communication training module was acceptable and effective, albeit in this small and highly-experienced physician sample. Future research should determine its effectiveness on communication in clinical settings. Innovation: This is the first physician training module to focus on communicating about clinical trials in a diverse patient population. It offers a web-based format and re-enactments of naturally-occurring clinical interactions.Trial Registration Number: NCT02906241.

A Review of Research on Disparities in the Care of Black and White Patients With Cancer in Detroit.

Racial disparities in cancer incidence and outcomes are well-documented in the US, with Black people having higher incidence rates and worse outcomes than White people. In this review, we present a summary of almost 30 years of research conducted by investigators at the Karmanos Cancer Institute's (KCI's) Population Studies and Disparities Research (PSDR) Program focusing on Black-White disparities in cancer incidence, care, and outcomes. The studies in the review focus on individuals diagnosed with cancer from the Detroit Metropolitan area, but also includes individuals included in national databases. Using an organizational framework of three generations of studies on racial disparities, this review describes racial disparities by primary cancer site, disparities associated with the presence or absence of comorbid medical conditions, disparities in treatment, and disparities in physician-patient communication, all of which contribute to poorer outcomes for Black cancer patients. While socio-demographic and clinical differences account for some of the noted disparities, further work is needed to unravel the influence of systemic effects of racism against Black people, which is argued to be the major contributor to disparate outcomes between Black and White patients with cancer. This review highlights evidence-based strategies that have the potential to help mitigate disparities, improve care for vulnerable populations, and build an equitable healthcare system. Lessons learned can also inform a more equitable response to other health conditions and crises.

Effects of culturally targeted message framing on colorectal cancer screening among African Americans.

OBJECTIVE: This study examined how standard and culturally targeted versions of gain and loss-framed messaging affect African Americans' colorectal cancer (CRC) screening receptivity and behavior, as well as their anticipation of experiencing racism in undertaking CRC screening. METHOD: Screening-deficient African Americans (N = 457) viewed an informational video about CRC risks, prevention, and screening and were randomized to receive a gain or loss-framed message about screening. Half of participants viewed an additional culturally targeted message about overcoming racial disparities in CRC by obtaining screening. Using the Theory of Planned Behavior, we measured general receptivity to CRC screening. We also measured arousal of anticipatory racism in response to messaging. Finally, we offered participants a no-cost fecal immunochemical testing kit (FIT Kit) and measured uptake and use. RESULTS: Message framing interacted with culturally targeted messaging to affect CRC screening receptivity and behavior. Participants were no more receptive to CRC screening when standard loss-framing was used, but were more favorable if loss-framing was culturally targeted. Targeted loss-framing also reduced anticipatory racism, which partially mediated effects on screening receptivity. Finally, although participants least often accepted a FIT Kit with standard loss-framing, effects of messaging on FIT Kit uptake and use were not significant. CONCLUSION: This study adds to growing recognition of important cultural nuance in effective use of message framing. Current finding also suggest that targeted and framed messaging could synergistically impact the extent to which African Americans engage in CRC screening, although specific impacts on FIT Kit screening are less certain.

Examining the dynamic nature of nonverbal communication between Black patients with cancer and their oncologists.

BACKGROUND: Although communication quality is associated with patient outcomes, racial disparities in communication exist, disproportionately burdening Black patients. However, most communication research focuses on verbal behaviors in predominantly White patient populations. We used a newly developed and theory-guided network analysis that examines the dynamic interplay and behavioral convergence and divergence between Black patients with cancer and their oncologists during cancer treatment discussions. METHODS: We applied a nonverbal behavioral coding system to thin slices of video recordings of Black patients and their oncologists discussing treatment. We then estimated 3 networks: 1) a temporal network to determine whether a nonverbal behavior predicts another nonverbal behavior at the next time point in an interaction, and how much each nonverbal behavior influences other nonverbal behaviors and is influenced by other nonverbal behaviors; 2) a contemporaneous network to determine whether a nonverbal behavior co-occurs with other nonverbal behaviors at the same time point in an interaction; and 3) a between-dyads network to examine the covariation between nonverbal behaviors across all dyads. RESULTS: Black patients (n = 74) and their non-Black physicians (n = 15) showed a mix of convergence and divergence in their nonverbal behaviors at the same points in time, from one time point to the next, and across dyads. Across analyses, convergence was most likely to occur when physicians matched their behaviors to their patients; especially with smiling, gaze, leaning, and laughter behaviors. CONCLUSION: Our findings reveal patterns of modifiable behaviors that can potentially inform interventions to reduce disparities in clinical communication and, in turn, treatment and mortality disparities.

Willingness to Discuss Clinical Trials Among Black vs White Men With Prostate Cancer.

IMPORTANCE: Black individuals are underrepresented in cancer clinical trials. OBJECTIVE: To examine whether Black and White men with prostate cancer differ in their willingness to discuss clinical trials with their physicians and, if so, whether patient-level barriers statistically mediate racial differences. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional survey study used baseline data from Partnering Around Cancer Clinical Trials, a randomized clinical trial to increase Black individuals' enrollment in prostate cancer clinical trials. Data were collected from 2016 through 2019 at 2 National Cancer Institute-designated comprehensive cancer centers; participants were Black and White men with intermediate-risk to high-risk prostate cancer. In mediation analysis, path models regressed willingness onto race and each potential mediator, simultaneously including direct paths from race to each mediator. Significant indirect effect sizes served as evidence for mediation. EXPOSURES: Race was the primary exposure. Potential mediators included age, education, household income, perceived economic burden, pain/physical limitation, health literacy, general trust in physicians, and group-based medical suspicion. MAIN OUTCOMES AND MEASURES: The primary outcome was the answer to a single question: "If you were offered a cancer clinical trial, would you be willing to hear more information about it?" RESULTS: A total of 205 participants were included (92 Black men and 113 White men), with a mean (range) age of 65.7 (45-89) years; 32% had a high school education or lower, and 27.5% had a household income of less than $40 000. Most (88.3%) reported being definitely or probably willing to discuss trials, but White participants were more likely to endorse this highest category of willingness than Black participants (82% vs 64%; χ22 = 8.81; P = .01). Compared with White participants, Black participants were younger (F1,182 = 8.67; P < .001), less educated (F1,182 = 22.79; P < .001), with lower income (F1,182 = 79.59; P < .001), greater perceived economic burden (F1,182 = 42.46; P < .001), lower health literacy (F1,184 = 9.84; P = .002), and greater group-based medical suspicion (F1,184 = 21.48; P < .001). Only group-based medical suspicion significantly mediated the association between race and willingness to discuss trials (indirect effect, -0.22; P = .002). CONCLUSIONS AND RELEVANCE: In this study of men with prostate cancer, most participants were willing to discuss trials, but Black men were significantly less willing than White men. Black men were more likely to believe that members of their racial group should be suspicious of the health care system, and this belief was associated with lower willingness to discuss trials. Addressing medical mistrust may improve equity in clinical research.

Applied Racial/Ethnic Healthcare Disparities Research Using Implicit Measures.

Many healthcare disparities studies use the Implicit Association Test (IAT) to assess bias. Despite ongoing controversy around the IAT, its use has enabled researchers to reliably document an association between provider implicit prejudice and provider-to-patient communication (provider communication behaviors and patient reactions to them). Success in documenting such associations is likely due to the outcomes studied, study settings, and data structure unique to racial/ethnic healthcare disparities research. In contrast, there has been little evidence supporting the role of providers' implicit bias in treatment recommendations. Researchers are encouraged to use multiple implicit measures to further investigate how, why, and under what circumstances providers' implicit bias predicts provider-to-patient communication and treatment recommendations. Such efforts will contribute to the advancement of both basic social psychology/social cognition research and applied health disparities research: a better understanding of implicit social cognition and a more comprehensive identification of the sources of widespread racial/ethnic healthcare disparities, respectively.

Unpacking Trial Offers and Low Accrual Rates: A Qualitative Analysis of Clinic Visits With Physicians and Patients Potentially Eligible for a Prostate Cancer Clinical Trial.

PURPOSE: Cancer clinical trial accrual rates are low, and information about contributing factors is needed. We examined video-recorded clinical interactions to identify circumstances under which patients potentially eligible for a trial at a major cancer center were offered a trial. METHODS: We conducted a qualitative directed content analysis of 62 recorded interactions with physicians (n = 13) and patients with intermediate- or high-risk prostate cancer (n = 43). Patients were screened and potentially eligible for a trial. We observed and coded the interactions in 3 steps: (1) classification of all interactions as explicit offer, offer pending, trial discussed/not offered, or trial not discussed; (2) in interactions with no explicit offer, classification of whether the cancer had progressed; (3) in interactions classified as progression but no trial offered, identification of factors discussed that may explain the lack of an offer. RESULTS: Of the 62 interactions, 29% were classified as explicit offer, 12% as offer pending, 18% as trial discussed/not offered, and 39% as trial not discussed. Of those with no offer, 57% included information that the cancer had not progressed. In 68% of the remaining interactions with patients whose cancer had progressed but did not receive an offer, reasons for the lack of offer were identified, but in 32%, no explanation was provided. CONCLUSION: Even in optimal circumstances, few patients were offered a trial, often because their cancer had not progressed. Findings support professional recommendations to broaden trial inclusion criteria. Findings suggest accrual rates should reflect the proportion of eligible patients who enroll.

Understanding differences in the long-term psychosocial adjustment of pediatric cancer patients and their parents: an individual differences resources model.

The experience of childhood cancer is a major life stressor for children and their parents. There is substantial variability among pediatric cancer patients and their parents in their ability to cope with the cancer. Although other models typically focus on the psychological resources families use to broadly cope with a diagnosis of pediatric cancer, we present a model that focuses specifically how parents and children cope with the stress of invasive and often painful treatment episodes. Our resources model is further distinct with its focus on individual differences in personal (e.g., personality traits) and social (e.g., social support) resources and the role these differences may play in psychosocial adjustment of families confronting pediatric cancer. We use findings from the broader pediatric cancer research literature and our own 15-year program of research on individual differences in psychological resources and parents and children's responses to treatment episodes to provide empirical support for our model. Support was found for the six premises of the model: (a) parent resources influence their longer-term psychosocial adjustment, (b) parent resources influence children's responses to treatment episodes, (c) parent resources indirectly influence their longer-term psychosocial adjustment through their responses to treatment episodes, (d) children's personal resources influence how parent responses to treatment episodes, (e) children's resources influence their longer-term psychosocial adjustment, and (f) children's resources indirectly influence their longer-term psychosocial adjustment through their responses to treatment episodes. Understanding how the availability of resources influences parents and children confronting cancer provides a foundation for future research on individual differences in resources and offers other avenues through which clinicians can assess and treat families at risk for poor psychosocial adjustment during treatment and in their life beyond cancer treatments.

Nonverbal synchrony as a behavioural marker of patient and physician race-related attitudes and a predictor of outcomes in oncology interactions: protocol for a secondary analysis of video-recorded cancer treatment discussions.

INTRODUCTION: Racial disparities in cancer treatment contribute to racial disparities in mortality rates. The quality of patient-physician communication during clinical interactions with black patients and non-black physicians (racially discordant) is poorer than communication quality with white patients (racially concordant). Patient and physician race-related attitudes affect the quality of this communication. These attitudes are likely expressed through subtle non-verbal behaviours, but prior research has not examined these behaviours. Nonverbal synchrony, the coordination of physical movement, reflects the preinteraction attitudes of participants in interactions and predicts their postinteraction perceptions of and affect towards one another. In this study, peer reviewed and funded by the National Institute of Minority Health and Health Disparities (R21MD011766), we will investigate non-verbal synchrony in racially concordant and discordant interactions to better understand racial disparities in clinical communication. METHODS AND ANALYSIS: This secondary analysis includes racially concordant (n=163) and racially discordant (n=68) video-recorded oncology interactions, patient and oncologist self-reported race-related attitudes, perceptions of the interaction and observer ratings of physician patient-centred communication and patient and physician affect and rapport. In aim 1, we will assess and compare non-verbal synchrony between physicians and patients in racially concordant and discordant interactions. In aim 2, we will determine the influence of non-verbal synchrony on patient and physician affect and communication. In aim 3, we will examine possible causes (ie, race-related attitudes) and consequences (ie, negative perceptions) of non-verbal synchrony in racially discordant interactions. In aim 4, we will develop and test a mediational model linking physician and patient race-related attitudes to non-verbal synchrony and, in turn, interaction outcomes. ETHICS AND DISSEMINATION: The parent and current studies were approved by the Wayne State University Institutional Review Board. Since only archival data will be used, ethical or safety risks are low. We will disseminate our findings to relevant conferences and journals.

The influence of affective behavior on impression formation in interactions between black cancer patients and their oncologists.

OBJECTIVE: Black patients and their physicians tend to form relatively negative impressions of each other, and these may contribute to racial disparities in health outcomes. The current research tested the hypothesis that the interaction between positive and negative affective behavior predicts the most positive impressions in clinic visits between Black patients and their oncologists. METHOD: Naïve coders rated patients' and oncologists' positive and negative affective behavior in thin slices from 74 video recorded clinic visits. We examined whether (a) physician positive affect, negative affect, or their interaction predicted patients' perceptions of patient-centeredness, trustworthiness, and confidence in recommended treatments and (b) patient positive affect, negative affect, or their interaction predicted physicians' perceptions of patient cognitive ability, likelihood of treatment adherence, and likelihood of treatment tolerance. We also tested whether affective behavior mediated relationships between race-related attitudes and post-visit impressions or influenced post-visit impressions independently of attitudes. RESULTS: When oncologists displayed relatively high levels of both positive and negative affect, patients were more confident in recommended treatments but did not rate physicians higher in patient centeredness or trustworthiness. When patients expressed relatively high levels of positive and negative affect, oncologists perceived patients to be higher in cognitive ability and more likely to adhere to treatment recommendations, but no more likely to tolerate treatments. Affective behavior influenced impressions independently of race-related attitudes. CONCLUSIONS: Positive and negative affective behaviors jointly contribute to impression formation in clinic visits between Black patients and oncologists, and may have implications for patient treatment and outcomes in this underserved patient population.

Longitudinal Analysis of Parent Communication Behaviors and Child Distress during Cancer Port Start Procedures.

BACKGROUND: The roles parents play in supporting their child during painful cancer procedures have been studied as communication strategies versus a broader caring framework and from a cross-sectional versus longitudinal perspective. OBJECTIVES: To examine the longitudinal change in parent communication behaviors over repeated cancer port start procedures experienced by their children. METHODS: This study used a longitudinal design. Two trained raters coded 104 recorded videos of port starts from 43 children being treated for cancer. This included 25 children with two video-recorded port starts and 18 children with three (T1, T2, T3). The Parent Caring Response Scoring System derived from Swanson's Caring Theory was used to code parent communication behaviors as caring responses during their children's port starts. Three 3- to 5-minute slices (pre-port start, during, and post-port start) were coded for each video. Mixed modeling with generalized estimating equations and Friedman test were used to analyze longitudinal change in parent behaviors. RESULTS: Significant differences were found between T1 versus T3 in eye contact (ß = -1.05, p = .02), distance-close-enough-to-touch (ß = -0.81, p = .03), nonverbal comforting (ß = -1.34, p = .04), and availability (ß = -0.92, p = .036), suggesting that more parents used communication behaviors at T3 compared with T1. Parent burdensome or intrusive questions (e.g., Why do you cry? ß = -1.11, p = .03) and nonverbal comforting (ß = -1.52, p = .047) increased from T2 to T3. The median values of parent communication behaviors overall had no significant changes from T1 to T3. CONCLUSION: Parents adjusted to use more nonverbal caring behaviors as their child experienced additional port starts. Experimental studies should be designed to help parents use caring behaviors to better support their children during cancer procedures.

Parent Caring Response Scoring System: development and psychometric evaluation in the context of childhood cancer-related port starts.

RATIONALE: Multiple observational coding systems have been developed and validated to assess parent-child interactions during painful procedures. Most of these coding systems are neither theory-based nor do they well represent parent nonverbal behaviours. AIMS: Develop the Parent Caring Response Scoring System (P-CaReSS) based on Swanson's Theory of Caring and test its psychometric properties in children in cancer port starts. METHODS: A hybrid approach of inductive and deductive coding was used to formulate the preliminary observational codes for the P-CaReSS. Twenty-nine children, each with one video-recording of port start available, were selected from the parent study (R01CA138981) to refine the P-CaReSS, train coders and test inter-rater reliability. Videos of another 43 children were used to evaluate the construct validity of P-CaReSS. Per cent agreement and Cohen's kappa were used to present the inter-rater reliability. Spearman rank-order correlations were used to report the construct validity. RESULTS: The 18-item P-CaReSS includes three types of parent behaviours: verbal, nonverbal and emotional behaviours. These parent interaction behaviours comprise five caring domains - knowing, being with, doing for, enabling, and maintaining belief - and one noncaring domain. On average the per cent agreement was 0.82 for the P-CaReSS overall, with average per cent agreements above 0.80 for both verbal and nonverbal behaviours. Kappa coefficient was 0.81 for the emotional behaviour. The behavioural codes in the P-CaReSS showed significant correlations with independent ratings of parent distress, child distress and child cooperation. CONCLUSIONS: The P-CaReSS is a promising tool that can be used to evaluate parent verbal, nonverbal and emotional behaviours during cancer-related port starts. This observational tool can be used to guide the development of nursing interventions to help parents caring for their child during cancer procedures.

Latent Semantic Analysis: A new measure of patient-physician communication.

RATIONALE: Patient-physician communication plays an essential role in a variety of patient outcomes; however, it is often difficult to operationalize positive patient-physician communication objectively, and the existing evaluation tools are generally time-consuming. OBJECTIVE: This study proposes semantic similarity of the patient's and physician's language in a medical interaction as a measure of patient-physician communication. Latent semantic analysis (LSA), a mathematical method for modeling semantic meaning, was employed to assess similarity in language during clinical interactions between physicians and patients. METHODS: Participants were 132 Black/African American patients (76% women, Mage = 43.8, range = 18-82) who participated in clinical interactions with 17 physicians (53% women, Mage = 27.1, range = 26-35) in a primary care clinic in a large city in the Midwestern United States. RESULTS: LSA captured reliable information about patient-physician communication: The mean correlation indicating similarity between the transcripts of a physician and patient in a clinical interaction was 0.142, significantly greater than zero; the mean correlation between a patient's transcript and transcripts of their physician during interactions with other patients was not different from zero. Physicians differed significantly in the semantic similarity between their language and that of their patients, and these differences were related to physician ethnicity and gender. Female patients exhibited greater communication similarity with their physicians than did male patients. Finally, greater communication similarity was predicted by less patient trust in physicians prior to the interaction and greater patient trust after the interaction. CONCLUSION: LSA is a potentially important tool in patient-physician communication research. Methodological considerations in applying LSA to address research questions in patient-physician communication are discussed.

Partnering around cancer clinical trials (PACCT): study protocol for a randomized trial of a patient and physician communication intervention to increase minority accrual to prostate cancer clinical trials.

BACKGROUND: Cancer clinical trials are essential for testing new treatments and represent state-of-the-art cancer treatment, but only a small percentage of patients ever enroll in a trial. Under-enrollment is an even greater problem among minorities, particularly African Americans, representing a racial/ethnic disparity in cancer care. One understudied cause is patient-physician communication, which is often of poor quality during clinical interactions between African-American patients and non-African-American physicians. Partnering Around Cancer Clinical Trials (PACCT) involves a transdisciplinary theoretical model proposing that patient and physician individual attitudes and beliefs and their interpersonal communication during racially discordant clinical interactions influence outcomes related to patients' decisions to participate in a trial. The overall goal of the study is to test a multilevel intervention designed to increase rates at which African-American and White men with prostate cancer make an informed decision to participate in a clinical trial. METHODS/DESIGN: Data collection will occur at two NCI-designated comprehensive cancer centers. Participants include physicians who treat men with prostate cancer and their African-American and White patients who are potentially eligible for a clinical trial. The study uses two distinct research designs to evaluate the effects of two behavioral interventions, one focused on patients and the other on physicians. The primary goal is to increase the number of patients who decide to enroll in a trial; secondary goals include increasing rates of physician trial offers, improving the quality of patient-physician communication during video recorded clinical interactions in which trials may be discussed, improving patients' understanding of trials offered, and increasing the number of patients who actually enroll. Aims are to 1) determine the independent and combined effects of the two interventions on outcomes; 2) compare the effects of the interventions on African-American versus White men; and 3) examine the extent to which patient-physician communication mediates the effect of the interventions on the outcomes. DISCUSSION: PACCT has the potential to identify ways to increase clinical trial rates in a diverse patient population. The research can also improve access to high quality clinical care for African American men bearing the disproportionate burden of disparities in prostate and other cancers.

Parents' Verbal and Nonverbal Caring Behaviors and Child Distress During Cancer-Related Port Access Procedures: A Time-Window Sequential Analysis.

PURPOSE/OBJECTIVES: To study the relationship between parental verbal and nonverbal caring behaviors and child distress during cancer-related port access placement using correlational and time-window sequential analyses.
. DESIGN: Longitudinal, observational design.
. SETTING: Children's Hospital of Michigan and St. Jude Children's Research Hospital.
. SAMPLE: 43 child-parent dyads, each with two or three video recordings of the child undergoing cancer-related port placement.
. METHODS: Two trained raters coded parent interaction behaviors and child distress using the Parent Caring Response Scoring System and Karmanos Child Coping and Distress Scale, respectively. Mixed modeling with generalized estimating equations examined the associations between parent interaction behaviors and parent distress, child distress, and child cooperation reported by multiple raters. Time-window sequential analyses were performed to investigate the temporal relationships in parent-child interactions within a five-second window.
. MAIN RESEARCH VARIABLES: Parent caring behaviors, child distress, and child cooperation.
. FINDINGS: Parent caring interaction behaviors were significantly correlated with parent distress, child distress, and child cooperation during repeated cancer port accessing. Sequential analyses showed that children were significantly less likely to display behavioral and verbal distress following parent caring behaviors than at any other time. If a child is already distressed, parent verbal and nonverbal caring behaviors can significantly reduce child behavioral and verbal distress.
. CONCLUSIONS: Parent caring behaviors, particularly the rarely studied nonverbal behaviors (e.g., eye contact, distance close to touch, supporting/allowing), can reduce the child's distress during cancer port accessing procedures.
. IMPLICATIONS FOR NURSING: Studying parent-child interactions during painful cancer-related procedures can provide evidence to develop nursing interventions to support parents in caring for their child during painful procedures.

The impact of Black cancer patients' race-related beliefs and attitudes on racially-discordant oncology interactions: A field study.

OBJECTIVE: Both physician and patient race-related beliefs and attitudes are contributors to racial healthcare disparities, but only the former have received substantial research attention. Using data from a study conducted in the Midwestern US from 2012 to 2014, we investigated whether 114 Black cancer patients' existing race-related beliefs and attitudes would predict how they and 18 non-Black physicians (medical oncologists) would respond in subsequent clinical interactions. METHOD: At least two days before interacting with an oncologist for initial discussions of treatment options, patients completed measures of perceived past discrimination, general mistrust of physicians, and suspicion of healthcare systems; interactions were video-recorded. Measures from each interaction included patients' verbal behavior (e.g., level of verbal activity), patients' evaluations of physicians (e.g., trustworthiness), patients' perceptions of recommended treatments (e.g., confidence in treatment), physicians' evaluations of patient personal attributes (e.g., intelligence) and physicians' expectations for patient treatment success (e.g., adherence). RESULTS: As predicted, patients' race-related beliefs and attitudes differed in their associations with patient and physician responses to the interactions. Higher levels of perceived past discrimination predicted more patient verbal activity. Higher levels of mistrust also predicted less patient positive affect and more negative evaluations of physicians. Higher levels of suspicion predicted more negative evaluations of physicians and recommended treatments. Stronger patient race-related attitudes were directly or indirectly associated with lower physician perceptions of patient attributes and treatment expectations. CONCLUSION: Results provide new evidence for the role of Black patients' race-related beliefs and attitudes in racial healthcare disparities and suggest the need to measure multiple beliefs and attitudes to identify these effects.

Strategies for enhancing research in aging health disparities by mentoring diverse investigators.

INTRODUCTION: The Resource Centers for Minority Aging Research (RCMAR) program was launched in 1997. Its goal is to build infrastructure to improve the well-being of older racial/ethnic minorities by identifying mechanisms to reduce health disparities. METHODS: Its primary objectives are to mentor faculty in research addressing the health of minority elders and to enhance the diversity of the workforce that conducts elder health research by prioritizing the mentorship of underrepresented diverse scholars. RESULTS: Through 2015, 12 centers received RCMAR awards and provided pilot research funding and mentorship to 361 scholars, 70% of whom were from underrepresented racial/ethnic groups. A large majority (85%) of RCMAR scholars from longstanding centers continue in academic research. Another 5% address aging and other health disparities through nonacademic research and leadership roles in public health agencies. CONCLUSIONS: Longitudinal, team-based mentoring, cross-center scholar engagement, and community involvement in scholar development are important contributors to RCMAR's success.
