Daily meaningfulness among patients with opioid use disorder: Examining the role of social experiences during residential treatment and links with post-treatment relapse

Effect of cognitive-behavioural therapy on resilience and relapse in adult patients with substance use disorder: a systematic review protocol

INTRODUCTION

Approximately 0.5 million fatalities per year are attributed to substance use disorder (SUD). SUD is refractory to therapy and has a high relapse rate. Cognitive deficits are also common in patients with SUD. Cognitive-behavioural therapy (CBT) is a promising treatment that may build resilience and reduce relapse among people with SUD. Our planned systematic review aims to clarify the effect of CBT on resilience and the relapse rate in adult patients with SUD compared with treatment as usual or no intervention.

METHODS AND ANALYSIS

We will search the Scopus, Web of Science, PubMed, Medline, Cochrane, EBSCO CINAHL, EMBASE and PsycINFO databases from inception to July 2023 for all relevant randomised controlled or quasiexperimental trials published in English. The follow-up period of included studies must be at least 8 weeks. The PICO (Population, intervention, control, and outcome) format was used to develop the search strategy. Search terms will be combined using boolean operators and have been customised for different databases. The Cochrane tool for randomised controlled trials will be used to assess the risk of bias in included studies. Extracted data will include bibliographic data, sample size, intervention method, summary of the findings, follow-up duration and effect sizes with standard errors. A random effects model will be used to combine effect measures. Subgroup analyses will be performed by CBT type, sex and SUD subtype, as applicable. I² statistics will be used to evaluate heterogeneity, and funnel plots will be used to address publication bias. If we detect significant heterogeneity, the findings will be reported as a systematic review without a meta-analysis.

ETHICS AND DISSEMINATION

Ethical approval is not required for this study. The findings will be submitted for publication in a peer-reviewed journal.

Examining Within- and Between-Person Facets of Negative Affect and Associations with Daily Craving Among Young Adults in Substance Use Disorder Recovery

The role of negative affect in precipitating drug craving and relapse among young adults in recovery from substance use disorder (SUD) is well documented. However, most studies focus on negative affect as a trait-level congregate of multiple negative emotion states. The present study examined the associations between specific facets of negative affect, college stressors, and craving among young adult college students in SUD recovery. Data were drawn from a three-week daily diary study of 50 students participating in a collegiate recovery community at a U.S. university (M age = 21.42, 76% males). At the within-person level, craving was higher on days when young adults experienced higher than usual anger, fear, and sadness, but not guilt. At the between-person level, individuals higher in agitation reported greater levels of craving on average. Moderation analyses further showed that college stressors heightened the within-person association between anger and craving. Findings demonstrate that negative affect is not monolithic and that its different aspects are uniquely associated with craving at both between- and within-person levels. Findings from this study could guide collegiate SUD recovery programs that wish to provide greater support to their members by helping them identify both individual- and time-specific relapse risks, such as generally high levels of agitation or days when anger, fear, or sadness are higher than usual for a particular individual. Our findings also suggest that future research should consider distinct features and implications of affective structures at between- and within-person levels, and how these may be uniquely associated with craving.

The protective effect of operant social reward on cocaine self-administration, choice, and relapse is dependent on delay and effort for the social reward

Social reinforcement-based treatments are effective for many, but not all, people with addictions to drugs. We recently developed an operant rat model that mimics features of one such treatment, the community-reinforcement approach. In this model, rats uniformly choose social interaction over methamphetamine or heroin. Abstinence induced by social preference protects against the incubation of drug-seeking that would emerge during forced abstinence. Here, we determined whether these findings generalize to cocaine and whether delaying or increasing effort for social interaction could reveal possibly human-relevant individual differences in responsiveness. We trained male and female rats for social self-administration (6 days) and then for cocaine self-administration, initially for 2-h/day for 4 days, and then for 12-h/day continuously or intermittently for 8 days. We assessed relapse to cocaine seeking after 1 and 15 days. Between tests, the rats underwent either forced abstinence or social-choice-induced abstinence. After establishing stable social preference, we manipulated the delay for both rewards or for social reward alone, or the response requirements (effort) for social reward. Independent of cocaine-access conditions and sex, operant social interaction inhibited cocaine self-administration and prevented incubation of cocaine seeking. Preference for social access was decreased by the delay of both rewards or social reward alone, or by increased response requirements for social reward, with notable individual variability. This choice procedure can identify mechanisms of individual differences in an animal model of cocaine use and could thereby help screen medications for people who are relatively unresponsive to treatments based on rewarding social interaction.

Within-person methodology to study the addiction recovery process of women

Women are among the fastest growing populations of those with substance use disorders in the United States. Women face different social barriers than men in their access to treatment and recovery from these disorders. Differentially experienced barriers include greater child caregiving responsibilities, social sigma regarding motherhood and substance use, romantic partners who also use substances, experiences of violence and trauma, and, relatedly, symptoms of post-traumatic stress disorder. These barriers have been studied primarily by employing between-group approaches (e.g. comparing men and women) or between-persons approaches (e.g. cross-sectionally assessing the relationship between person-level PTSD symptoms and relapse). However, there are limited studies on women's gender-specific experiences in recovery with the aim of elucidating within-person effects. Employing within-person designs, such as daily diary or ecological momentary assessments, has many advantages. These advantages include reducing retrospective bias, assessing temporality of processes that occur on a short time scale, and analyzing processes that may occur when individuals deviate from their personally normative experiences. Studying women's experiences in recovery "as they are lived" will enable the development of interventions that are fine-tuned to the specific needs of each woman, and ultimately may help to reduce the suffering of women with substance use disorders.

Psychosocial Needs of Parents Engaged in Treatment for Opioid Use Disorder

Background: Little research has examined the needs of parents with opioid use disorder (OUD) who are receiving medications for OUD (MOUDs), which is striking given growing rates of OUD among parents. Objective: The current study expands the literature by examining psychiatric, psychosocial, and parenting-related functioning, as well as 12-month MOUD treatment retention among parents versus non-parents participating in a buprenorphine program at an academic family medicine residency clinic. Methods: Patients (N = 144; 61 parents) completed measures of psychiatric and psychosocial functioning at the first MOUD visit; parents also completed measures of parental functioning. Results: Parents endorsed less anxiety and loneliness, as well as greater social connection, life satisfaction, and life meaning. Parents were also older, more likely to be female, of a race other than white, married, employed, and had higher incomes. Although parents endorsed high levels of parental self-agency and strong bonds with children, many also reported elevated parental shame. Among parents, higher levels of shame were also associated with higher depression, anxiety, anger, stress, and loneliness. Over 25% of parents reported that a child lived with friends/relatives over 3 months, and 11% noted a child having been removed from the home by child protective services. Finally, parents were more likely to be retained in treatment at 12 months, although this finding was non-significant after controlling for covariates. Conclusions/Importance: These findings illustrate the needs experienced by parents engaged in MOUD treatment, which may prove valuable in informing policy, program development, and treatment approaches for parents with OUD.
