Randomized Controlled Trial Evaluating the Effectiveness of a Direct-to-Consumer Marketing Video About Patients' Right to Evidence-Based Mental Health Care.

ABSTRACT: This study evaluated the impact of a direct-to-consumer (DTC) marketing video designed to educate the public about patients' rights to evidence-based mental health care (EBMHC). Participants (N = 632) were randomly assigned to an active DTC video condition, a control video condition, or a control condition without a video. Participants who watched the DTC video (vs. both control conditions) had significantly greater knowledge of patients' rights to EBMHC. Further, individuals who watched the DTC (vs. control) video reported significantly greater comfort with accessing care and perceived their assigned video as significantly more culturally sensitive. However, participants who watched the DTC video were not significantly different from both control conditions on self-report measures of self-efficacy in working with a provider, likelihood of asking a provider about one's rights, treatment-seeking intentions, and self-stigma. Findings suggest the potential for a DTC video to promote knowledge of EBMHC, though its impact on help-seeking perceptions and intentions was less promising.

Web-based interpretation bias training to reduce anxiety: A sequential, multiple-assignment randomized trial.

OBJECTIVE: Web-based cognitive bias modification for interpretation (CBM-I) can improve interpretation biases and anxiety symptoms but faces high rates of dropout. This study tested the effectiveness of web-based CBM-I relative to an active psychoeducation condition and the addition of low-intensity telecoaching for a subset of CBM-I participants. METHOD: 1,234 anxious community adults (Mage = 35.09 years, 81.2% female, 72.1% white, 82.6% not Hispanic) were randomly assigned at Stage 1 of a sequential, multiple-assignment randomized trial to complete five weekly sessions of CBM-I or psychoeducation on our team's public research website. After the first session, for Stage 2, an algorithm attempted to classify CBM-I participants as higher (vs. lower) risk for dropping out; those classified as higher risk were then randomly assigned to complete four brief weekly telecoaching check-ins (vs. no coaching). RESULTS: As hypothesized (https://doi.org/j2xr; Daniel, Eberle, & Teachman, 2020), CBM-I significantly outperformed psychoeducation at improving positive and negative interpretation biases (Recognition Ratings, Brief Body Sensations Interpretation Questionnaire) and anxiety symptoms (Overall Anxiety Severity and Impairment Scale, Anxiety Scale from Depression Anxiety Stress Scales-Short Form), with smaller treatment gains remaining significant at 2-month follow-up. Unexpectedly, CBM-I had significantly worse treatment dropout outcomes than psychoeducation, and adding coaching (vs. no coaching) did not significantly improve efficacy or dropout outcomes (notably, many participants chose not to interact with their coach). CONCLUSIONS: Web-based CBM-I appears effective, but supplemental coaching may not mitigate the challenge of dropout. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Providing Human Support for the Use of Digital Mental Health Interventions: Systematic Meta-review.

BACKGROUND: Digital mental health interventions (DMHIs) have been increasingly deployed to bridge gaps in mental health care, particularly given their promising efficacy. Nevertheless, attrition among DMHI users remains high. In response, human support has been studied as a means of improving retention to and outcomes of DMHIs. Although a growing number of studies and meta-analyses have investigated the effects of human support for DMHIs on mental health outcomes, systematic empirical evidence of its effectiveness across mental health domains remains scant. OBJECTIVE: We aimed to summarize the results of meta-analyses of human support versus no support for DMHI use across various outcome domains, participant samples, and support providers. METHODS: We conducted a systematic meta-review of meta-analyses, comparing the effects of human support with those of no support for DMHI use, with the goal of qualitatively summarizing data across various outcome domains, participant samples, and support providers. We used MEDLINE, PubMed, and PsycINFO electronic databases. Articles were included if the study had a quantitative meta-analysis study design; the intervention targeted mental health symptoms and was delivered via a technology platform (excluding person-delivered interventions mediated through telehealth, text messages, or social media); the outcome variables included mental health symptoms such as anxiety, depression, stress, posttraumatic stress disorder symptoms, or a number of these symptoms together; and the study included quantitative comparisons of outcomes in which human support versus those when no or minimal human support was provided. RESULTS: The results of 31 meta-analyses (505 unique primary studies) were analyzed. The meta-analyses reported 45 effect sizes; almost half (n=22, 48%) of them showed that human-supported DMHIs were significantly more effective than unsupported DMHIs. A total of 9% (4/45) of effect sizes showed that unsupported DMHIs were significantly more effective. No clear patterns of results emerged regarding the efficacy of human support for the outcomes assessed (including anxiety, depression, posttraumatic stress disorder, stress, and multiple outcomes). Human-supported DMHIs may be more effective than unsupported DMHIs for individuals with elevated mental health symptoms. There were no clear results regarding the type of training for those providing support. CONCLUSIONS: Our findings highlight the potential of human support in improving the effects of DMHIs. Specifically, evidence emerged for stronger effects of human support for individuals with greater symptom severity. There was considerable heterogeneity across meta-analyses in the level of detail regarding the nature of the interventions, population served, and support delivered, making it difficult to draw strong conclusions regarding the circumstances under which human support is most effective. Future research should emphasize reporting detailed descriptions of sample and intervention characteristics and describe the mechanism through which they believe the coach will be most useful for the DMHI.

Implementation of a Technology-Enhanced Peer Mentor Referral System for First-Year University Students.

COVID-19 forced college administrators to reassess how they provide students with the most effective methods of support. This project examined the first year of a novel digital peer mentoring program with the goal of connecting diverse students to campus resources they needed to navigate the transition to and through their first year of college. MentorHub, a referral and supportive accountability mobile application, was implemented with first-year undergraduates at a large, private university in the northeastern region of the USA. MentorHub tracked students' current challenges and connected them with trained peer mentors who provided students with support and referrals to campus resources (e.g., mental health, financial, academic). Analyses were not hypothesis-driven, but instead were exploratory and intended for improving the platform. In the first year of the program (August 2021 to June 2022), 47% (N = 3141) students logged onto the platform at least once. Patterns of self-reported challenges revealed that career concerns were the most challenging at the beginning of the fall semester, and that academic habits were most challenging over the course of the year. Referrals (N = 756) were made by mentors, 13% of which were for health and well-being. First-generation and underrepresented minority students showed distinct patterns in referrals. Findings revealed distinct patterns in self-reported challenges across the academic year. Students' use of MentorHub and responses to in-app questions allowed for a real-time understanding of student challenges and patterns of engagement with peer mentors. Implications for a stepped-care approach to addressing student challenges are discussed.

Striking the Balance: The Relative Benefits of Goal- and Youth-Focused Approaches to Youth Mentoring Relationships.

Targeted, goal-focused approaches to mentoring can improve behavioral and mental health outcomes than more recreational, non-specific approaches. However, a focus on goals needs to be balanced with openness to including mentees' preferences. This study builds on prior work by exploring the benefits of goal- and youth-focused approaches to mentoring relationships from the youth mentee's perspective, including their associations with relationship measures (closeness and tension) and mental health outcomes (i.e., conduct problems, emotional symptoms, and depressive symptoms). This study was a secondary analysis of data from 2165 youth participating in thirty nationally representative mentoring programs in the United States. On average, youth were 12.3-years-old (SD = 1.43, range = 9-16) and the majority were female (55%); 36.7% were Black/African American, 22.4% were White, and 23.5% were Latino/Hispanic. Path analyses revealed 1) youth- and goal-focused approaches were positively associated with closeness, 2) youth-focused approaches were negatively associated with tension, 3) goal-focused approaches were positively associated with tension. At follow-up, a stronger mentoring relationship (less tension and greater closeness) was related to positive youth outcomes. As the field of mentoring corrects for an overemphasis on intuitive approaches and moves towards more targeted directions, it should resist veering too far from what sets the field apart from skills-training models: the role of a caring relationship.

Implicit and explicit COVID-19 associations and mental health in the United States: a large-scale examination and replication.

BACKGROUND: Given the sensitive nature of COVID-19 beliefs, evaluating them explicitly and implicitly may provide a fuller picture of how these beliefs vary based on identities and how they relate to mental health. OBJECTIVE: Three novel brief implicit association tests (BIATs) were created and evaluated: two that measured COVID-19-as-dangerous (vs. safe) and one that measured COVID-19 precautions-as-necessary (vs. unnecessary). Implicit and explicit COVID-19 associations were examined based on individuals' demographic characteristics. Implicit associations were hypothesized to uniquely contribute to individuals' self-reports of mental health. METHODS: Participants (N = 13,413 US residents; April-November 2020) were volunteers for a COVID-19 study. Participants completed one BIAT and self-report measures. This was a preregistered study with a planned internal replication. RESULTS: Results revealed older age was weakly associated with stronger implicit and explicit associations of COVID-as-dangerous and precautions-as-necessary. Black and Asian individuals reported greater necessity of taking precautions than White individuals (with small-to-medium effects); greater education was associated with greater explicit reports of COVID-19-as-dangerous and precautions-as-necessary with small effects. Replicated relationships between COVID-as-dangerous explicit associations and mental health had very small effects. CONCLUSIONS: Implicit associations did not predict mental health but there was evidence that stronger COVID-19-as-dangerous explicit associations are weakly associated with worse mental health.

The role of uncertainty, worry, and control in well-being: Evidence from the COVID-19 outbreak and pandemic in U.S. and China.

Uncertainty about the future often leads to worries about what the future will bring, which can have negative consequences for health and well-being. However, if worry can act as a motivator to promote efforts to prevent undesirable future outcomes, those negative consequences of worry may be mitigated. In this article, we apply a novel model of uncertainty, worry, and perceived control to predict psychological and physical well-being among four samples collected in China (Study 1; during the early COVID-19 outbreak in China) and the United States (Studies 2-4, during 4 weeks in May 2020, 4 weeks in November 2020, and cross-sectionally between April and November 2020). Grounded in the feeling-is-for-doing approach to emotions, we hypothesized (and found) that uncertainty about one's COVID-19 risk would predict greater worry about the virus and one's risk of contracting it, and that greater worry would in turn predict poorer well-being. We also hypothesized, and found somewhat mixed evidence, that perceptions of control over 1's COVID-19 risk moderated the relationship between worry and well-being such that worry was related to diminished well-being when people felt they lacked control over their risk for contracting the virus. This study is one of the first to demonstrate an indirect path from uncertainty to well-being via worry and to demonstrate the role of control in moderating whether uncertainty and worry manifest in poor well-being.

Digital Mental Health Services: Moving From Promise to Results.

The papers in this special issue make a compelling case for the value of digital mental health services (DMHS; including technology-based interventions, assessments, and prevention programs) to help address some of the currently unmet needs in mental health care. At the same time, the papers highlight the work that needs to be accomplished for DMHS to fulfill their promise. We review the papers' contributions in terms of (a) the imperative to increase access to evidence-informed, high-quality care, especially for underserved populations, both in the United States and globally; (b) ways to use DMHS to improve the ways that clinical care is provided to make treatment provision more effective and efficient; and (c) the current state of the research on DMHS for emotional disorders. We then consider lessons learned and recommendations to move the field forward, such as increasing (and making transparent) the research base on DMHS, adopting regulatory standards for DMHS, attending carefully to training issues for DMHS and best practices for dissemination and implementation, designing specifically for digital platforms, and being intentional about efforts to reduce disparities regarding who benefits from DMHS.

Lessons Learned: Providing Supportive Accountability in an Online Anxiety Intervention.

Technology-delivered interventions have the potential to help address the treatment gap in mental health care but are plagued by high attrition. Adding coaching, or minimal contact with a nonspecialist provider, may encourage engagement and decrease dropout, while remaining scalable. Coaching has been studied in interventions for various mental health conditions but has not yet been tested with anxious samples. This study describes the development of and reactions to a low-intensity coaching protocol administered to N = 282 anxious adults identified as high risk to drop out of a web-based cognitive bias modification for interpretation intervention. Undergraduate research assistants were trained as coaches and communicated with participants via phone calls and synchronous text messaging. About half of the sample never responded to coaches' attempts to schedule an initial phone call or did not answer the call, though about 30% completed the full intervention with their coach. Some anxious adults may choose technology-delivered interventions specifically for their lack of human contact and may fear talking to strangers on the phone; future recommendations include taking a more intensive user-centered design approach to creating and implementing a coaching protocol, allowing coaching support to be optional, and providing users with more information about how and why the intervention works.

Paraprofessional Youth Mentoring: A Framework for Integrating Youth Mentoring with Helping Institutions and Professions.

The demand for child mental health services, including those provided by psychologists, counselors, and social workers, exceeds the supply. This trend is expected to continue or worsen unless there are substantial structural changes in how mental health services are provided. We propose a framework for paraprofessional youth mentors, defined as a subgroup of professionally supervised, non-expert volunteer or paid mentors to whom aspects of professional helping tasks are delegated. Our proposal is aligned with historical and modern solutions to scaling mental health services, and this framework could simultaneously increase the number of youth receiving evidence-based mental health services and reduce the burden on existing systems of care. The framework defines three plausible tasks for paraprofessional mentors: (1) reducing barriers to mental health service, (2) increasing engagement in services, and (3) providing direct services. The safety and effectiveness of these task-shifting efforts will hinge on competency-based training and evaluation, supervision by professionals, and documentation of services rendered, all of which the field of youth mentoring currently lacks. We describe several requisite scientific, institutional, and regulatory advances that will be necessary to realize this variant of youth mentoring for a subgroup of youth who are presenting for assistance with mental health problems.

Implicit and Explicit Beliefs About the Effectiveness of Psychotherapy vs. Medication: A Large-Scale Examination and Replication.

ABSTRACT: One exploratory study (N = 10,335) and one preregistered replication and extension study (N = 6648) evaluated implicit and explicit beliefs in the effectiveness of psychotherapy versus medication, and whether these beliefs vary as a function of demographics, mental health difficulties, and treatment experiences. Data were collected from a sample of visitors to a mental health research website who completed the Therapy vs. Medication Effectiveness Implicit Association Test (IAT). The IAT demonstrated evidence of convergent validity with two measures of explicit therapy versus medication effectiveness beliefs. Across both studies, individuals held greater implicit and explicit beliefs that therapy is more effective than medication, and individuals who were Black (versus all other races, excluding "other/unknown") and who had experienced past (versus current) mental health difficulties had stronger implicit and explicit beliefs in the effectiveness of therapy versus medication. More work is needed to understand how these differences in beliefs arise, as well as to evaluate the clinical utility of this novel measure.

Which variations of a brief cognitive bias modification session for interpretations lead to the strongest effects?

BACKGROUND: Brief computerized programs that train less threatening interpretations (termed Cognitive Bias Modification for Interpretations, or CBM-I) can shift interpretation biases and subsequent anxiety symptoms. However, results have been inconsistent, particularly for studies conducted over the Internet. METHODS: The current exploratory study tests 13 variations of a single brief session of CBM-I, a non-CBM-I cognitive flexibility condition, a neutral condition, and a no task control condition in an analogue sample with moderate to severe anxiety. RESULTS: Results suggest that all conditions, except the neutral scenarios condition and the alternative way to improve cognitive flexibility, led to changes in interpretations (when compared to the no task control condition). Only conditions geared toward increasing imagery during CBM-I and targeting flexibility related to emotional material differed from the no task control condition on other post-training measures. CONCLUSIONS: Presenting valenced interpretations of ambiguous information during brief CBM-I, regardless of the format, can lead to changes in interpretation bias. However, most conditions did not differ from the no task control condition on other post-training assessments (and differences that did occur may be due to chance). Future trials should consider further testing of CBM-I that targets flexibility related to emotional material, and should include an increased number of sessions and trials.

Clinical psychology PhD students' admission experiences: Implications for recruiting racial/ethnic minority and LGBTQ students.

AIM: The purpose of this study was to explore differences in the clinical psychology PhD program admissions experience (i.e., interviewing and decision-making) by race/ethnicity and lesbian, gay, bisexual, transgender, and queer (LGBTQ) identity. METHODS: Participants were 803 students (24% racial/ethnic minority; 19% LGBTQ) enrolled in US clinical psychology PhD programs. Two-group comparisons tested for differences in admission experiences by race/ethnicity and LGBTQ identity. RESULTS: Racial/ethnic minority and LGBTQ students considered a programmatic commitment to diversity as more important in application decisions compared to non-Hispanic White and cisgender heterosexual students, respectively. LGBTQ students were more likely to be advised to not discuss personal information (e.g., sexual orientation) than cisgender heterosexual students. Racial/ethnic minority and LGBTQ students identified financial considerations and program outcomes as more important in their decision-making compared with non-Hispanic White and cisgender heterosexual students, respectively. CONCLUSION: Increasing funding and fostering authentic training environments should be prioritized in institutional conversations around recruiting racial/ethnic minority and LGBTQ trainees.

Improving the reach of clinical practice guidelines: An experimental investigation of message framing on user engagement.

Despite strong evidence for the efficacy of PTSD treatments, most affected individuals are not receiving these treatments, in part because they may not know that evidence-based treatments exist. The American Psychological Association published a website to disseminate information about their Clinical Practice Guideline for treating PTSD. In Study 1, Google Optimize was used in a field study to examine whether altering the subheadings to three of the website pages would increase site visitor engagement. On the main page and page describing treatments, no subheading alterations improved engagement. On the Patients and Families page, the subheading "say goodbye to symptoms" improved engagement on three outcome variables, including clicking a link to find a psychologist (though there were a small number of clicks). In a preregistered conceptual replication in a sample not actively seeking information about the PTSD guideline (N=578), results did not replicate. Results highlight challenges of evidence-based treatment information dissemination.

Implicit Cognition and Psychopathology: Looking Back and Looking Forward.

Implicit cognitive processing is theorized to have a central role in many forms of psychopathology. In the current review, we focus on implicit associations, by which we mean evaluative representations in memory that are difficult to control and do not require conscious reflection to influence affect, cognition, or behavior. We consider definitional and measurement challenges before examining recent empirical evidence for these associations in anxiety, obsessive-compulsive, posttraumatic stress, depressive, and alcohol use disorders. This examination is framed by a brief review of the ways that prominent models of psychopathology represent biased implicit processing of disorder-relevant information. We consider to what extent models reflect more traditional automatic/implicit versus strategic/explicit dual-process perspectives or reflect more recent dynamical systems perspectives in which mental representations are iteratively reprocessed, evolving continuously. Finally, we consider the future research needed to better understand the interactive and temporal dynamics of implicit cognition in psychopathology.

Remembering or knowing how we felt: Depression and anxiety symptoms predict retrieval processes during emotional self-report.

Researchers and clinicians routinely rely on patients' retrospective emotional self-reports to guide diagnosis and treatment, despite evidence of impaired autobiographical memory and retrieval of emotional information in depression and anxiety. To clarify the nature and specificity of these impairments, we conducted two large online data collections (Study 1, N = 1,983; Study 2, N = 900) examining whether depression and/or anxiety symptoms would uniquely predict the use of self-reported episodic (i.e., remembering) and/or semantic (i.e., knowing) retrieval when rating one's positive and negative emotional experiences over different time frames. Participants were randomly assigned to one of six time frames (ranging from at this moment to last few years) and were asked to rate how intensely they felt each of four emotions, anxious, sad, calm, and happy, over that period. Following each rating, they were asked several follow-up prompts assessing their perceived reliance on episodic and/or semantic information to rate how they felt, using procedures adapted from the traditional "remember/know" paradigm (Tulving, 1985). Across both studies, depression and anxiety symptoms each uniquely predicted increased likelihood of remembering across emotion types, and decreased likelihood of knowing how one felt when rating positive emotion types. Implications for the theory and treatment of emotion-related memory disturbances in depression and anxiety, and for dual-process theories of memory retrieval more generally, are discussed.

Implicit health associations across the adult lifespan.

OBJECTIVE: Explicit reports of one's health self-concept (e.g. rate your overall health) are commonly used in research and clinical practice. These measures predict important health outcomes, but rely on conscious introspection so may not fully capture the different components of the health self-concept (e.g. more automatic components) that relate to actual health. This study examined the health-implicit association test (health-IAT), and how it may add to our prediction of health from self-reports. DESIGN: 1004 participants (ages 18-85) completed this web-based study with the health-IAT (assessing self-healthy implicit associations) and explicit assessments of health. MAIN OUTCOME MEASURES: Self-reported measures of physical functioning. RESULTS: The health-IAT was valid and reliable. Older age was correlated with stronger self-healthy implicit associations. Although the health-IAT did not incrementally predict self-reported markers of physical functioning when only controlling for explicit health self-concept, it was an incremental predictor once age was entered for all four models tested. CONCLUSIONS: The health-IAT appears to be a valid and reliable new measure that assesses implicit self-concept relating to physical health. Results reveal the potential value of assessing implicit health self-concept in both research and practice, especially when taking into account age.

Suicide and self-injury-related implicit cognition: A large-scale examination and replication.

Suicide and self-injury are difficult to predict because at-risk individuals are often unable or unwilling to report their intentions. Therefore, tools to reliably assess risk without reliance on self-report are critically needed. Prior research suggests that people who engage in suicidal and nonsuicidal self-injury (NSSI) often implicitly (i.e., outside conscious control) associate themselves with self-harm and death, indicating that self-harm-related implicit cognition may serve as a useful behavioral marker for suicide risk. However, earlier studies left several critical questions about the robustness, sensitivity, and specificity of self-harm-related implicit associations unaddressed. We recruited a large sample of participants (N = 7,015) via a public web-based platform called Project Implicit Mental Health (PIMH) to test several hypotheses about self-harm-related implicit associations using the Implicit Association Test (IAT). Participants were randomly assigned to complete 1 of 3 self-harm IATs (Self + Cutting using picture stimuli, Self + Suicide using word stimuli, Self + Death using word stimuli). Results replicated prior studies demonstrating that self-harm-related implicit associations were stronger among individuals with (vs. without) a history of suicide attempt and NSSI. Results also suggested that self-harm-related implicit associations are robust (based on internal replication), are sensitive to recency and severity of self-harm history (e.g., stronger associations for more recent and more lethal prior suicide attempts), and correlate with specific types of self-harm behaviors. These findings clarify the nature of self-harm-related implicit cognition and highlight the IAT's potential to track current risk for specific types of self-harm in ways that more fixed risk factors cannot.

Moderators of age effects on attention bias toward threat and its association with anxiety.

OBJECTIVE: The current study used a research domain criteria (RDoC) approach to assess age differences in multiple indicators of attention bias and its ties to anxiety, examining stimulus domain and cognitive control as moderators of older adults' oft-cited positivity effect (bias towards positive and away from negative stimuli, when compared to younger adults). METHOD: 38 Younger adults and 38 older adults were administered a battery of cognitive control and trait and state anxiety measures, and completed a dot-probe task to assess attention bias, during which reaction time and fixation duration (using eye-tracking) were recorded for negative and neutral social (a salient threat domain for younger adults) and physical (a salient threat domain for older adults) stimuli. RESULTS: Mixed-effects models demonstrated that older adults were faster to react to dot-probe trials when the probe appeared in the place of negative (vs. neutral) physical stimuli, but displayed no difference in reaction time for social stimuli. Also, older (vs. younger) adults with lower levels of cognitive control were less negatively biased in their visual fixation to social stimuli. A negative reaction time attention bias on the dot-probe task predicted greater trait anxiety among participants with low levels of cognitive control, with a more complex pattern predicting state anxiety. CONCLUSION: Older adults do attend to social and physical stimuli differently. When stimuli concern a social threat, older adults do not preferentially attend to either neutral or negative stimuli. However, when stimuli concern physical threat, older adults preferentially attend to negative stimuli. Threat biases are associated with anxiety at all ages for those with low cognitive control.

Towards greater understanding of addiction stigma: Intersectionality with race/ethnicity and gender.

BACKGROUND: In spite of the significant burden associated with substance use disorders, especially among persons who inject drugs (PWIDs), most affected individuals do not engage with any type of formal or informal treatment. Addiction stigma, which is represented by negative social attitudes toward individuals who use alcohol and/or other drugs, is one of the barriers to care that is poorly understood. The current study: a) assessed implicit (indirect and difficult to consciously control) and explicit (consciously controlled) beliefs about PWIDs among visitors to a public web site; and b) experimentally investigated the effects of ethnicity/race and gender on those implicit and explicit beliefs. METHODS: N=899 predominantly White (70%) and women (62%) were randomly assigned to one of six target PWIDs conditions: gender (man/woman) x race/ethnicity (White, Black, Latino/a). Participants completed an Implicit Association Test and explicit assessment of addiction stigma. RESULTS: Participants implicitly associated PWIDs (especially Latino/a vs. White PWIDs) with deserving punishment as opposed to help (p=0.003, d=0.31), indicating presence of addiction stigma-related implicit beliefs. However, this bias was not evident on the explicit measure (p=0.89). Gender did not predict differential implicit or explicit addiction stigma (p=0.18). CONCLUSIONS: Contrary to explicit egalitarian views towards PWIDs, participants' implicit beliefs were more in line with addiction stigma. If replicated and clearer ties to behavior are established, results suggest the potential importance of identifying conditions under which implicit bias might influence behavior (even despite explicit egalitarian views) and increase the likelihood of discrimination towards PWIDs.
