Conspiracy theories have been proliferating during the COVID-19 pandemic. Evidence suggests that belief in conspiracy theories undermines engagement in pro-health behaviors and support for public health policies. Moreover, previous work suggests that inoculating messages from opinion leaders that expose conspiracy theories as false before people are exposed to them can help to prevent belief in new conspiracies. Goals of this study were to: (a) explore associations between COVID-19 conspiracy beliefs with SARS-CoV-2 vaccine intentions, cooperation with public health recommendations, and support for public health policies among U.S. adults and (b) investigate trusted sources of COVID-19 information to inform strategies to address conspiracy beliefs. A cross-sectional, online survey was conducted with 845 U.S. adults in April 2020. Data were analyzed using analyses of variance and multivariable regressions. One-third (33%) of participants believed one or more conspiracies about COVID-19. Participants who believed conspiracies reported that their intentions to vaccinate were 3.9 times lower and indicated less support for COVID-19 public health policies than participants who disbelieved conspiracies. There were no differences in cooperation with public health recommendations by conspiracy belief endorsement in the multivariable regression analysis. Although there were some key differences in trusted sources of COVID-19 information, doctor(s) were the most trusted source of information about COVID-19 overall with 90% of participants trusting doctor(s). Doctor(s) may play a role in addressing COVID-19 conspiracy theories before people are exposed to them to promote COVID-19 prevention efforts.

Although the last decade has seen a proliferation of research on mental illness stigma, lack of consistency and clarity in both the conceptualization and measurement of mental illness stigma has limited the accumulation of scientific knowledge about mental illness stigma and its consequences. In the present article, we bring together the different foci of mental illness stigma research with the Mental Illness Stigma Framework (MISF).The MISF provides a common framework and set of terminology for understanding mechanisms of mental illness stigma that are relevant to the study of both the stigmatized and the stigmatizer. We then apply this framework to systematically review and classify stigma measures used in the past decade according to their corresponding stigma mechanisms. We identified more than 400 measures of mental illness stigma, two thirds of which had not undergone any systematic psychometric evaluation. Stereotypes and discrimination received the most research attention, while mechanisms that focus on the perspective of individuals with mental illness (e.g., experienced, anticipated, or internalized stigma) have been the least studied. Finally, we use the MISF to discuss the strengths and weaknesses of mental illness stigma measurement, identify gaps in the literature, and provide recommendations for future research.

This trial assessed the feasibility, acceptability, tolerability, and efficacy of an Internet-based therapist-assisted cognitive-behavioral indicated prevention intervention for prolonged grief disorder (PGD) called Healthy Experiences After Loss (HEAL). Eighty-four bereaved individuals at risk for PGD were randomized to either an immediate treatment group (n = 41) or a waitlist control group (n=43). Assessments were conducted at four time-points: prior to the wait-interval (for the waitlist group), pre-intervention, post-intervention, 6 weeks later, and 3 months later (for the immediate group only). Intent-to-treat analyses indicated that HEAL was associated with large reductions in prolonged grief (d=1.10), depression (d=.71), anxiety (d=.51), and posttraumatic stress (d=.91). Also, significantly fewer participants in the immediate group met PGD criteria post-intervention than in the waitlist group. Pooled data from both groups also yielded significant reductions and large effect sizes in PGD symptom severity at each follow-up assessment. The intervention required minimal professional oversight and ratings of satisfaction with treatment and usability of the Internet interface were high. HEAL has the potential to be an effective, well-tolerated tool to reduce the burden of significant pre-clinical PGD. Further research is needed to refine HEAL and to assess its efficacy and mechanisms of action in a large-scale trial.

Instant messaging (IM) has become one of the most popular forms of computer-mediated communication (CMC) and is especially prevalent on college campuses. Previous research suggests that IM users often multitask while conversing online. To date, no one has yet examined the cognitive effect of concurrent IM use. Participants in the present study (N = 69) completed a reading comprehension task uninterrupted or while concurrently holding an IM conversation. Participants who IMed while performing the reading task took significantly longer to complete the task, indicating that concurrent IM use negatively affects efficiency. Concurrent IM use did not affect reading comprehension scores. Additional analyses revealed that the more time participants reported spending on IM, the lower their reading comprehension scores. Finally, we found that the more time participants reported spending on IM, the lower their self-reported GPA. Implications and future directions are discussed.

Many veterans who would benefit from mental health care do not seek treatment. The current study provided an in-depth examination of mental health-related beliefs and their relationship with mental health and substance abuse service use in a national sample of 640 U.S. Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans. Both concerns about mental health stigma from others and personal beliefs about mental illness and mental health treatment were examined. Data were weighted to adjust for oversampling of women and nonresponse bias. Results revealed substantial variation in the nature of OEF/OIF veterans' mental health beliefs, with greater anticipated stigma in the workplace (M = 23.74) than from loved ones (M = 19.30), and stronger endorsement of negative beliefs related to mental health treatment-seeking (M = 21.78) than either mental illness (M = 18.56) or mental health treatment (M = 20.34). As expected, individuals with probable mental health problems reported more negative mental health-related beliefs than those without these conditions. Scales addressing negative personal beliefs were related to lower likelihood of seeking care (ORs = 0.80-0.93), whereas scales addressing anticipated stigma were not associated with service use. Findings can be applied to address factors that impede treatment seeking.
