Bots and Misinformation Spread on Social Media: Implications for COVID-19.

As of March 2021, the SARS-CoV-2 virus has been responsible for over 115 million cases of COVID-19 worldwide, resulting in over 2.5 million deaths. As the virus spread exponentially, so did its media coverage, resulting in a proliferation of conflicting information on social media platforms-a so-called "infodemic." In this viewpoint, we survey past literature investigating the role of automated accounts, or "bots," in spreading such misinformation, drawing connections to the COVID-19 pandemic. We also review strategies used by bots to spread (mis)information and examine the potential origins of bots. We conclude by conducting and presenting a secondary analysis of data sets of known bots in which we find that up to 66% of bots are discussing COVID-19. The proliferation of COVID-19 (mis)information by bots, coupled with human susceptibility to believing and sharing misinformation, may well impact the course of the pandemic.

The American Society of Addiction Medicine Clinical Practice Guideline Development Methodology.

ABSTRACT: The American Society of Addiction Medicine (ASAM) has published clinical practice guidelines (CPGs) since 2015. As ASAM's CPG work continues to develop, it maintains an organizational priority to establish rigorous standards for the trustworthy production of these important documents. In keeping with ASAM's mission to define and promote evidence-based best practices in addiction prevention, treatment, and recovery, ASAM has rigorously updated its CPG methodology to be in line with evolving international standards. The CPG Methodology and Oversight Subcommittee was formed to establish and publish a methodology for the development of ASAM CPGs and to develop an ASAM CPG strategic plan. This article provides a focused overview of the ASAM CPG methodology.

Women's Substance Use and Mental Health During the COVID-19 Pandemic.

PURPOSE: Women are experiencing greater unemployment and increased stress from childcare responsibilities than men during the COVID-19 pandemic. Women with these experiences may be at particular risk for mental illness and increased substance use during the COVID-19 pandemic. The purpose of the study was to assess women's substance use, mental health, and experiences of COVID-19 pandemic impacts. METHODS: A national online survey was administered to adult women from September to November 2020. The survey included questionnaires assessing mental health, loneliness, intolerance for uncertainty, social support, substance use, and intimate partner violence (IPV). RESULTS: A total of 499 women responded; most were White, college educated, and in their mid-30s. Of the 20.24% who acknowledged at least one IPV problem, 29.7% stated that their IPV problems have gotten worse since the pandemic began, and 16.83% said that they have increased their drug or alcohol use to cope with their relationship problems. Anxiety, perceived daily impact of COVID-19, and lower self-efficacy were significant predictors of COVID-19 anxiety. Those with risky alcohol use had significantly higher anxiety (p = .028) and depression (p = .032) than those with low-risk alcohol use. CONCLUSIONS: Greater anxiety about COVID-19, greater reported changes in daily life due to the pandemic, and high-risk alcohol use are related to greater mental health-related distress among women. For some, IPV has gotten worse during the pandemic and drug or alcohol use is a coping mechanism.

A Systematic Review of Treatment Maintenance Strategies in Token Economies: Implications for Contingency Management.

Contingency management (CM) interventions are based on operant principles and are effective in promoting health behaviors. Despite their success, a common criticism of CM is that its effects to not persist after the intervention is withdrawn. Many CM studies evaluate posttreatment effects, but few investigate procedures for promoting maintenance. Token economy interventions and CM interventions are procedurally and conceptually similar. The token economy literature includes many studies in which procedures for promoting postintervention maintenance are evaluated. A systematic literature review was conducted to synthesize the literature on treatment maintenance in token economies. Search procedures yielded 697 articles, and application of inclusion/exclusion criteria resulted in 37 articles for review. The most successful strategy is to combine procedures. In most cases, thinning or fading was combined with programmed transfer of control via social reinforcement or self-management. Social reinforcement and self-monitoring procedures appear to be especially important, and were included in 70% of studies involving combined approaches. Thus, our primary recommendation is to incorporate multiple maintenance strategies, at least one of which should facilitate transfer of control of the target behavior to other reinforcers. In addition, graded removal of the intervention, which has also been evaluated to a limited extent in CM, is a reasonable candidate for further development and evaluation. Direct comparisons of maintenance procedures are lacking, and should be considered a research priority in both domains. Researchers and clinicians interested in either type of intervention will likely benefit from ongoing attention to developments in both areas.

Getting "clean" from nonsuicidal self-injury: Experiences of addiction on the subreddit r/selfharm.

Background & Aims: Previous studies have shown that nonsuicidal self-injury (NSSI) has addictive features, and an addiction model of NSSI has been considered. Addictive features have been associated with severity of NSSI and adverse psychological experiences. Yet, there is debate over the extent to which NSSI and substance use disorders (SUDs) are similar experientially. Methods: To evaluate the extent that people who self-injure experience NSSI like an addiction, we coded the posts of users of the subreddit r/selfharm (n = 500) for each of 11 DSM-5 SUD criteria adapted to NSSI. Results: A majority (76.8%) of users endorsed at least two adapted SUD criteria in their posts, indicative of mild, moderate, or severe addiction. The most frequently endorsed criteria were urges or cravings (67.6%), escalating severity or tolerance (46.7%), and NSSI that is particularly hazardous. User-level addictive features positively predicted number of methods used for NSSI, number of psychiatric disorders, and particularly hazardous NSSI, but not suicidality. We also observed frequent use of language and concepts common in SUD recovery circles like Alcoholics Anonymous. Discussion & Conclusion: Our findings support previous work describing the addiction potential of NSSI and associating addictive features with clinical severity. These results suggest that NSSI and SUD may share experiential similarities, which has implications for the treatment of NSSI. We also contribute to a growing body of work that uses social media as a window into the subjective experiences of stigmatized populations.

Smartphone-based incentives for promoting adherence to antiretroviral therapy: A randomized controlled trial.

Antiretroviral therapy can improve the lives of people living with HIV and reduce the rate of transmission. However, high levels of adherence are required. Some people living with HIV, including people who use drugs, are at elevated risk for non-adherence. Contingency management is a promising intervention for promoting adherence to antiretroviral therapy. Barriers to adoption of contingency management include lack of provider expertise and implementation effort. To address these barriers, a smartphone-based adherence intervention was developed. HIV + people with a substance use disorder were required to submit video selfies of medication consumption that met validity criteria. Monetary incentives were delivered to participants via reloadable debit cards, contingent upon a valid video. The intervention was evaluated in a small (n = 50) randomized controlled trial. Intervention participants submitted 75% of possible videos, and 81% of videos met validity criteria, indicating a high level of usability. Participants also rated the intervention as highly acceptable. Adherence was measured as the percent of participants who achieved a 95% adherence threshold, and also as the overall percent of days in which participants were adherent to their antiretroviral therapy. The former showed a significant effect for group, (p = .034) but this was not maintained when adjusting for stratification variables as covariates (p = .094). The latter measure showed a significant group × time interaction. Smartphone-based contingency management is a promising method for promoting adherence to antiretroviral therapy. Assessing the cost-benefit of the intervention and development of strategies for long-term adherence are priorities for future research.

Acceptability and willingness to pay for contingency management interventions among parents of young adults with problematic opioid use.

BACKGROUND: There is a need for new research addressing the cost prohibitive nature of maintaining contingency management (CM) in community settings. While researchers propose managed care as an option to support costs, there is no research on self-pay models. To inform such research, it is important first to understand client willingness to pay for CM services. We examine acceptability and willingness to pay for CM services among parents with and without young adult children with problematic opioid use. METHODS: A web-based survey was administered to a sample of parents of adult children ages 18-35 with (target sample) and without (comparison sample) a history of problematic opiate use. RESULTS: One hundred thirty parents participated (ntarget = 30; ncomparison = 100) and were predominately white, college educated, and of higher income. Findings showed a high proportion of participants had positive opinions of using incentives for substance use treatment and would consider incentive-based treatments for their child. Most participants reported they would be willing to pay for CM at levels consistent with amounts used in efficacious programs but expressed worry that incentives would be used to buy drugs. Most participants reported this worry would be eased if incentives were delivered via reloadable gift cards and if incentives were only delivered during periods of abstinence. CONCLUSIONS: This is the first study to examine parent perceptions of incentives and acceptability and willingness to pay for CM services. Results suggest self-pay models for disseminating CM to young adults with problematic opioid use may be an option.
