ABSTRACT

Using data from Wave 3 of the Chicago Health and Life Experiences of Women (CHLEW) study (N = 699), we explored whether religiosity and spirituality were associated with risk of hazardous drinking, drug use, and depression among sexual minority women (SMW; i.e., lesbian, bisexual) and possible differences by race/ethnicity. Participants were more likely to endorse spirituality than religiosity, and endorsement of each was highest among African American SMW. We found no protective effect of religiosity or spirituality for hazardous drinking or drug use. An association initially found between identifying as very spiritual and past-year depression disappeared when controlling for help-seeking. Among SMW with high religiosity, African American SMW were more likely than White SMW to report hazardous drinking. Latina SMW with higher spirituality were more likely than White SMW to report drug use. Results suggest that religiosity and spirituality affect subgroups differently, which should be considered in future research on resiliency among SMW.

ABSTRACT

The authors of this study examined within-person associations of environmental factors (weather, built and social environmental barriers) and personal factors (daily hassles, affect) with moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) in African American women aged 25-64 years living in metropolitan Chicago (n = 97). In 2012-13, for seven days, women wore an accelerometer and were signaled five times per day to complete a survey covering environmental and personal factors on a study-provided smartphone. Day-level measures of each were derived, and mixed regression models were used to test associations. Poor weather was associated with a 27.3% reduction in daily MVPA. Associations between built and social environmental barriers and daily MVPA or SB were generally not statistically significant. Negative affect at the first daily signal was associated with a 38.6% decrease in subsequent daily MVPA and a 33.2-minute increase in subsequent daily SB. Each one-minute increase in MVPA during the day was associated with a 2.2% higher likelihood of positive affect at the end of the day. SB during the day was associated with lower subsequent positive affect. Real-time interventions that address overcoming poor weather and negative affect may help African American women increase MVPA and/or decrease SB.

ABSTRACT

BACKGROUND: Although sexual minority women (SMW) are at increased risk of hazardous drinking (HD), efforts to validate HD measures have yet to focus on this population. OBJECTIVES: Validation of a 13-item Hazardous Drinking Index (HDI) in a large sample of SMW. METHODS: Data were from 700 adult SMW (age 18-82) enrolled in the Chicago Health and Life Experiences of Women study. Criterion measures included counts of depressive symptoms and post-traumatic stress disorder (PTSD) symptoms, average daily and 30-day ethanol consumption, risky sexual behavior, and Diagnostic and Statistical Manual (DSM-IV) measures of alcohol abuse/dependence. Analyses included assessment of internal consistency, construction of receiver operating characteristic (ROC) curves to predict alcohol abuse/dependence, and correlations between HDI and criterion measures. We compared the psychometric properties (diagnostic accuracy and correlates of hazardous drinking) of the HDI to the commonly used CAGE instrument. RESULTS: KR-20 reliability for the HDI was 0.80, compared to 0.74 for the CAGE. Predictive accuracy, as measured by the area under the receiver operating characteristic curve for alcohol abuse/dependence, was HDI: 0.89; CAGE: 0.84. The HDI evidenced the best predictive efficacy and tradeoff between sensitivity and specificity. Results supported the concurrent validity of the HDI measure. CONCLUSIONS: The Hazardous Drinking Index is a reliable and valid measure of hazardous drinking for sexual minority women.

ABSTRACT

BACKGROUND: There is increasing evidence that neighborhood-level factors, in addition to individual-level factors, may contribute directly or indirectly to childhood asthma by affecting environmental and lifestyle factors. Exposure to neighborhood crime and violence has been associated with poor health outcomes, especially among underserved and minority populations, and its effect on respiratory health is an area of active research. OBJECTIVE: To examine the association of residential neighborhood crime with asthma and asthma-related outcomes among Mexican American children. METHODS: This cross-sectional study was conducted with parents of 2,023 Mexican American children. We derived measures of neighborhood (census tract) violent, property, and drug abuse crime and used multilevel generalized estimating equations to test associations of neighborhood crime counts with respiratory conditions. RESULTS: In multiple regression models, a 1-SD increase in neighborhood property crimes significantly increased the odds of lifetime asthma, lifetime wheezing, lifetime emergency department (ED) visits attributable to asthma or wheezing, and lifetime hospitalization attributable to asthma or wheezing by 25%, 18%, 44%, and 62%, respectively. A 1-SD elevation in neighborhood violent crime was positively and significantly associated with 21% and 57% higher odds of lifetime wheezing and ED visits, respectively. We also observed 13% and 44% significantly increased odds of lifetime wheezing and ED visits, respectively, for a 1-SD increase in drug abuse crime. These findings were not explained or modified by individual- and neighborhood-level covariates. CONCLUSION: Higher neighborhood crime was associated with greater odds of asthma and asthma morbidity in Mexican American children.

ABSTRACT

PURPOSE: This study describes the prevalence and predisposing factors for potentially modifiable unmet emotional, care/support, and information needs among adult survivors of childhood malignancies. METHODS: A randomly selected/stratified sample of participants in the Childhood Cancer Survivor Study (CCSS) responded to the CCSS-Needs Assessment Questionnaire (CCSS-NAQ) (n = 1189; mean [SD] current age, 39.7 [7.7], range = 26-61 years; 60.9 % women; mean [SD] years since diagnosis, 31.6 [4.7]). Survivors self-reported demographic information, health concerns, and needs; diagnosis/treatment data were obtained from medical records. Adjusted proportional risk ratios (prevalence ratios, PRs) were used to evaluate 77 separate needs. RESULTS: Fifty-four percent of survivors reported unmet psycho-emotional, 41 % coping, and 35 % care/support needs; 51, 35, and 33 %, respectively, reported unmet information needs related to cancer/treatment, the health care system, and surveillance. Female sex and annual income <$60K were associated with multiple needs; fewer needs were linked to diagnosis/years since/or age at diagnosis. Having moderate/extreme cancer-related anxiety/fear was associated with all needs, including a >6-fold increased prevalence for help dealing with "worry" (PR = 6.06; 95 % confidence interval [CI], 3.79-9.69) and anxiety (PR = 6.10; 95 % CI, 3.82-9.72) and a >5-fold increased prevalence for "needing to move on with life" (PR = 5.56; 95 % CI, 3.34-9.25) and dealing with "uncertainty about the future" (PR = 5.50; 95 % CI, 3.44-8.77). Radiation exposure and perceived health status were related to 42 and 29 needs, respectively. CONCLUSIONS: Demographic factors, disease/treatment characteristics, and intrapersonal factors can be used to profile survivors' unmet emotional, care/support, and information needs. IMPLICATIONS FOR CANCER SURVIVORS: These data can be used to enhance provider-survivor communication, identify at-risk subsamples, and appraise core intervention content.

ABSTRACT

The Theory of Planned Behavior (TpB) is useful to direct nursing research aimed at behavior change. As proposed in the TpB, individuals' attitudes, perceived norms, and perceived behavior control predict their intentions to perform a behavior and subsequently predict their actual performance of the behavior. Our purpose was to apply Fishbein and Ajzen's guidelines to begin development of a valid and reliable instrument for pediatric nurses' attitudes, perceived norms, perceived behavior control, and intentions to administer PRN opioid analgesics when hospitalized children self-report moderate to severe pain. Following Fishbein and Ajzen's directions, we were able to define the behavior of interest and specify the research population, formulate items for direct measures, elicit salient beliefs shared by our target population and formulate items for indirect measures, and prepare and test our questionnaire. For the pilot testing of internal consistency of measurement items, Cronbach alphas were between 0.60 and 0.90 for all constructs. Test-retest reliability correlations ranged from 0.63 to 0.90. Following Fishbein and Ajzen's guidelines was a feasible and organized approach for instrument development. In these early stages, we demonstrated good reliability for most subscales, showing promise for the instrument and its use in pain management research. Better understanding of the TpB constructs will facilitate the development of interventions targeted toward nurses' attitudes, perceived norms, and/or perceived behavior control to ultimately improve their pain behaviors toward reducing pain for vulnerable children.

ABSTRACT

Measures of body dissatisfaction have not been validated for Mexican American (MA) women, who evaluate their bodies differently than Caucasian women. In this study, the psychometric properties of the EDI-III, Body Dissatisfaction Subscale (BDS) were examined in a sample of college-enrolled MA women using the Rasch Rating Scale Model. Criterion validity was also addressed. BDS evidenced good item fit, person and item reliability, once poorly correlated items were removed. Two qualitatively distinct dimensions of body dissatisfaction were identified: (1) overall body shape and stomach, and (2) the lower body. Validity of the scales was supported. Results suggest: MA women's satisfaction with overall body shape is not synonymous with attitudes toward their lower body.

ABSTRACT

A well-known approach in computerized mastery testing is to combine the Sequential Probability Ratio Test (SPRT) stopping rule with item selection to maximize Fisher information at the mastery threshold. This article proposes a new approach in which a time limit is defined for the test and examinees' response times are considered in both item selection and test termination. Item selection is performed by maximizing Fisher information per time unit, rather than Fisher information itself. The test is terminated once the SPRT makes a classification decision, the time limit is exceeded, or there is no remaining item that has a high enough probability of being answered before the time limit. In a simulation study, the new procedure showed a substantial reduction in average testing time while slightly improving classification accuracy compared with the original method. In addition, the new procedure reduced the percentage of examinees who exceeded the time limit.

ABSTRACT

Disclosing one's sexual minority identity, or "coming out," has varying effects on the mental health of lesbians. Previous research indicates a negative association between disclosure and depression. However, these findings are based on research with White lesbians. To date, there is a paucity of studies that examined how the relationship between disclosure and depression may differ by race/ethnicity among lesbians. To address this gap, we examined the relationship between disclosure and depression among African American (26.5%), Latina (19.7%), and White (53.8%) self-identified lesbians (N = 351) in 2 survey-interviews (∼ 3-years apart). Over 50% of the participants reported a history of lifetime depression at baseline and 35.9% reported depression at Time 2 (T2). Disclosure levels varied: 78.9% had disclosed to their mother, 58.4% to their father, and 83.3% to a sibling. The mean level for disclosure to nonfamily individuals was 6.29 (SD 2.64; range 0-9). Disclosure results varied by race/ethnicity showing African American lesbians (vs. White lesbians) were less likely to disclose to nonfamily individuals when controlling for covariates. Results for the relationship between disclosure and depression showed disclosure to either parent or sibling was not associated with depression for the total sample. Among Latinas only, disclosure to nonfamily individuals was associated with less depression. Additional research is needed to explore racial/ethnic differences in disclosure with certain individuals and to better understand the relation between disclosure and depression. Findings have implications for reducing overall rates of depression among lesbians living with multiple-minority identities.

ABSTRACT

This study examined contributions of environmental and personal factors (specifically, food availability and expense, daily hassles, self-efficacy, positive and negative affect) to within-person and between-person variations in snack food intake in 100 African American women. Participants were signaled at random five times daily for seven days to complete a survey on a study-provided smartphone. Women reported consuming snack foods at 35.2% of signals. Easier food availability accounting for one's usual level was associated with higher snack food intake. Being near outlets that predominately sell snacks (e.g., convenience stores), while accounting for one's usual proximity to them, was associated with higher snack food intake. Accounting for one's usual daily hassle level, we found that on days with more frequent daily hassles snack food intake was higher. The positive association between within-person daily hassles frequency and snack food intake was stronger when foods were easily available. Public and private policies to curb ubiquitous food availability and mobile health interventions that take into account time-varying influences on food choices and provide real-time assistance in dealing with easy food availability and coping with stressors may be beneficial in improving African American women's day to day food choices.

ABSTRACT

OBJECTIVES: To explore disparities between non-Hispanic Blacks and non-Hispanic Whites presenting to the emergency department (ED) with potential acute coronary syndrome (ACS). BACKGROUND: Individuals with fewer resources have worse health outcomes and these individuals are disproportionately those of color. METHODS: This prospective study enrolled 663 patients in four EDs. Clinical presentation, treatment, and patient-reported outcome variables were measured at baseline, 1, and 6 months. RESULTS: Blacks with confirmed ACS were younger; had lower income; less education; more risk factors; more symptoms, and longer prehospital delay at presentation compared to Whites. Blacks experiencing palpitations, unusual fatigue, and chest pain were more than 3 times as likely as Whites to have ACS confirmed. Blacks with ACS had more clinic visits and more symptoms 1 month following discharge. CONCLUSIONS: Significant racial disparities remain in clinical presentation and outcomes for Blacks compared to Whites presenting to the ED with symptoms suggestive of ACS.

ABSTRACT

INTRODUCTION: We conducted a longitudinal evaluation of factors associated with persistent smoking behaviors among sexual minority women (SMW; lesbians and bisexual women). METHODS: Structured interview data were collected as part of a larger longitudinal study of SMW's health: the Chicago Health and Life Experiences of Women study. We conducted multivariate analyses to evaluate the influence of 4 groups of predictor variables on smoking: (a) demographic, (b) childhood victimization, (c) other substance use, and (d) health variables. RESULTS: At Wave 1, 30.9% (n = 138) of participants reported current smoking, with substance-use and demographic factors having the strongest relationships to smoking status. The majority (84.9%) of Wave 1 smokers were also smoking at Wave 2. Among demographic variables, level of education was inversely associated with continued smoking. With respect to substance use, hazardous drinking and cocaine/heroin use were significantly associated with continued smoking. None of the victimization or health variables predicted smoking status. CONCLUSIONS: Consistent with previous studies, smoking rates in this sample of SMW were elevated. Despite intensive efforts to reduce smoking in the general population, 84% of SMW smokers continued smoking from Wave 1 to Wave 2. Findings suggest that the majority of SMW will continue to smoke over time. Additional research is needed to increase motivation and access to smoking cessation resources.

ABSTRACT

Innovative, culturally tailored strategies are needed to extend diabetes education and support efforts in lower-resourced primary care practices serving racial/ethnic minority groups. A randomized controlled trial (RCT) examined the effect of a diabetes self-care coaching intervention delivered by medical assistants and the joint effect of intervention and ethnicity over time. The randomized repeated-measures design included 270 low-income African American and Hispanic/Latino patients with type 2 diabetes. The 1-year clinic- and telephone-based medical assistant coaching intervention was culturally tailored and guided by theoretical frameworks. A1C was obtained, and a self-care measure was completed at baseline, 6 months, and 12 months. Data were analyzed using mixed-effects models with and without adjustment for covariates. There was a significant overall improvement in mean self-care scores across time, but no intervention effect. Results revealed differences in self-care patterns across racial/ethnic subgroups. No differences were found for A1C levels across time or group.

ABSTRACT

BACKGROUND: Diabetes is a serious worldwide public health challenge. The burden of diabetes, including prevalence and risk of complications, is greater for minorities, particularly African Americans. Internet-based immersive virtual worlds offer a unique opportunity to reach large and diverse populations with diabetes for self-management education and support. OBJECTIVE: The objective of the study was to examine the acceptability, usage, and preliminary outcome of a virtual world intervention, Diabetes Island, in low-income African Americans with type 2 diabetes. The main hypotheses were that the intervention would: (1) be perceived as acceptable and useful; and (2) improve diabetes self-care (eg, behaviors and barriers) and self-care related outcomes, including glycemic control (A1C), body mass index (BMI), and psychosocial factors (ie, empowerment and distress) over six months. METHODS: The evaluation of the intervention impact used a single-group repeated measures design, including three assessment time points: (1) baseline, (2) 3 month (mid intervention), and (3) 6 month (immediate post intervention). Participants were recruited from a university primary care clinic. A total of 41 participants enrolled in the 6 month intervention study. The intervention components included: (1) a study website for communication, feedback, and tracking; and (2) access to an immersive virtual world (Diabetes Island) through Second Life, where a variety of diabetes self-care education activities and resources were available. Outcome measures included A1C, BMI, self-care behaviors, barriers to adherence, eating habits, empowerment, and distress. In addition, acceptability and usage were examined. A series of mixed-effects analyses, with time as a single repeated measures factor, were performed to examine preliminary outcomes. RESULTS: The intervention study sample (N=41) characteristics were: (1) mean age of 55 years, (2) 71% (29/41) female, (3) 100% (41/41) African American, and (4) 76% (31/41) reported annual incomes below US $20,000. Significant changes over time in the expected direction were observed for BMI (P<.02); diabetes-related distress (P<.02); global (P<.01) and dietary (P<.01) environmental barriers to self-care; one physical activity subscale (P<.04); and one dietary intake (P<.01) subscale. The participant feedback regarding the intervention (eg, ease of use, interest, and perceived impact) was consistently positive. The usage patterns showed that the majority of participants logged in regularly during the first two months, and around half logged in each week on average across the six month period. CONCLUSIONS: This study demonstrated promising initial results of an immersive virtual world approach to reaching underserved individuals with diabetes to deliver diabetes self-management education. This intervention model and method show promise and could be tailored for other populations. A large scale controlled trial is needed to further examine efficacy.

ABSTRACT

OBJECTIVE: This study aimed to examine diabetes self-care (DSC) patterns in low-income African American and Latino patients with Type 2 diabetes, and identify patient-related, biomedical/disease-related, and psychosocial correlates of DSC. METHOD: We performed cross-sectional analysis of survey data from African Americans and Latinos aged ≥18 years with Type 2 diabetes (n = 250) participating in a diabetes self-management intervention at 4 primary care clinics. The Summary of Diabetes Self-Care Activities captured the subcomponents of healthy eating, physical activity, blood sugar testing, foot care, and smoking. Correlates included patient-related attributes, biomedical/disease-related factors, and psychosocial constructs, with their multivariable influence assessed with a 3-step model building procedure using regression techniques. RESULTS: Baseline characteristics were as follows: mean age of 53 years (SD = 12.4); 69% female; 53% African American; 74% with incomes below $20,000; and 60% with less than a high school education. DSC performance levels were highest for foot care (4.5/7 days) and lowest for physical activity (2.5/7 days). Across racial/ethnic subgroups, diabetes-related distress was the strongest correlate for DSC when measured as a composite score. Psychosocial factors accounted for 14% to 33% of variance in self-care areas for both racial/ethnic groups. Patient characteristics were more salient correlates in Hispanic/Latinos when examining the self-care subscales, particularly those requiring monetary resources. CONCLUSIONS: Important information is provided on specific DSC patterns in a sample of ethnic/racial minorities with Type 2 diabetes. Significant correlates found may help with identification and intervention of patients who may benefit from strategies to increase self-care adherence.

ABSTRACT

PURPOSE: Examine the construct validity, stability, internal consistency, and item-response performance of a self-report health needs assessment for adult survivors of childhood cancer. METHODS: A 190-item mailed survey was completed by 1,178 randomly selected (stratified on age, diagnosis, time since diagnosis) Childhood Cancer Survivor Study participants (mean age, 39.66 [SD 7.71] years; time since diagnosis, 31.60 [SD 4.71] years). Minorities and rural residents were oversampled at a 2:1 ratio. RESULTS: The final instrument included 135 items comprising nine unidimensional subscales (Psycho-emotional, Health System Concerns, Cancer-Related Health Information, General Health, Survivor Care and Support, Surveillance, Coping, Fiscal Concerns, and Relationships). Confirmatory factor analysis (n = 1,178; RMSEA = 0.020; 90 % CI = 0.019-0.020; CFI = 0.956; TLI = 0.955) and person-item fit variable maps established construct validity. Across subscales, Cronbach's alpha was 0.94-0.97, and the 4-week test-retest correlations were 0.52-0.91. In a Rasch analysis, item reliability was 0.97-0.99, person reliability was 0.80-0.90, and separation index scores were 2.00-3.01. Significant subscale covariates of higher need levels included demographics, diagnosis, and treatment exposures. CONCLUSIONS: The Childhood Cancer Survivor Study Needs Assessment Questionnaire (CCSS-NAQ) is reliable and construct-valid, has strong item-response properties, and discriminates need levels. IMPLICATIONS FOR CANCER SURVIVORS: The CCSS-NAQ potentially can be used to: (1) directly assess adult childhood cancer survivors' self-reported health-related needs, (2) identify individuals or subgroups with higher-level needs, (3) inform prevention and direct intervention strategies, and (4) facilitate prioritization of health-care resource allocation.

ABSTRACT

BACKGROUND: Computerized adaptive testing (CAT) is being applied to health outcome measures developed as paper-and-pencil (P&P) instruments. Differences in how respondents answer items administered by CAT vs. P&P can increase error in CAT-estimated measures if not identified and corrected. METHOD: Two methods for detecting item-level mode effects are proposed using Bayesian estimation of posterior distributions of item parameters: (1) a modified robust Z (RZ) test, and (2) 95% credible intervals (CrI) for the CAT-P&P difference in item difficulty. A simulation study was conducted under the following conditions: (1) data-generating model (one- vs. two-parameter IRT model); (2) moderate vs. large DIF sizes; (3) percentage of DIF items (10% vs. 30%), and (4) mean difference in θ estimates across modes of 0 vs. 1 logits. This resulted in a total of 16 conditions with 10 generated datasets per condition. RESULTS: Both methods evidenced good to excellent false positive control, with RZ providing better control of false positives and with slightly higher power for CrI, irrespective of measurement model. False positives increased when items were very easy to endorse and when there with mode differences in mean trait level. True positives were predicted by CAT item usage, absolute item difficulty and item discrimination. RZ outperformed CrI, due to better control of false positive DIF. CONCLUSIONS: Whereas false positives were well controlled, particularly for RZ, power to detect DIF was suboptimal. Research is needed to examine the robustness of these methods under varying prior assumptions concerning the distribution of item and person parameters and when data fail to conform to prior assumptions. False identification of DIF when items were very easy to endorse is a problem warranting additional investigation.

ABSTRACT

This study used Rasch measurement model criteria and traditional psychometric strategies to examine key psychometric properties of the Behavioral Complexity Scale (BCS), a widely used measure of externalizing disorders that focuses on attention deficit, hyperactivity, and conduct disorders. With a sample of 7,435 persons being screened for substance use disorders, the BCS was found to (a) be unidimensional, (b) have a hierarchical severity structure, (c) be generalizable to both youths and adults, and (d) meet hypothesized correlations with criterion variables. The BCS performed well as a unidimensional measure. The Rasch severity hierarchy of attention deficit to hyperactivity to conduct disorders provided a perspective that suggested that a dimensional measure could be used as an alternative and, in some ways, as an improvement to categorical diagnosis and common dimensional approaches. The finding of 3 low-severity conduct disorder items also supported a revision of categorical criteria, especially in substance use disorders.

ABSTRACT

In assessing criminality, researchers have used counts of crimes, arrests, and so on, because interval measures were not available. Additionally, crime seriousness varies depending on demographic factors. This study examined the Crime and Violence Scale (CVS) regarding psychometric quality using item response theory (IRT) and invariance of the crime seriousness hierarchy for gender, age, and racial/ethnic groups on 7,435 respondents. The CVS is a useful measure of criminality, though some items could be improved or dropped. Differential item functioning (DIF) analysis revealed that crime seriousness varies by age and gender. IRT shows promise in assessing and adjusting for demographic variations in crime seriousness.

ABSTRACT

UNLABELLED: Symptoms of internalizing disorders (depression, anxiety, somatic, trauma) are the major risk factors for suicide. Atypical suicide risk is characterized by people with few or no symptoms of internalizing disorders. OBJECTIVE: In persons screened at intake to alcohol or other drug (AOD) treatment, this research examined whether person fit statistics would support an atypical subtype at high risk for suicide that did not present with typical depression and other internalizing disorders. METHODS: Symptom profiles of the prototypical, typical, and atypical persons, as defined using fit statistics, were tested on 7408 persons entering AOD treatment using the Global Appraisal of Individual Needs (GAIN; Dennis et al., 2003a,b). RESULTS: Of those with suicide symptoms, the findings were as expected with the atypical group being higher on suicide and lower on symptoms of internalizing disorders. In addition, the atypical group was similar or lower on substance problems, symptoms of externalizing disorders, and crime and violence. CONCLUSIONS: Person fit statistics were useful in identifying persons with atypical suicide profiles and in enlightening aspects of existing theory concerning atypical suicidal ideation.
