Addiction motivation reformulated: an affective processing model of negative reinforcement

Difficulties with positive, but not negative, emotion regulation moderate the association between positive alcohol expectancies and alcohol use in college students

Background

Positive alcohol expectancies are linked to increased alcohol use among college students. Difficulties regulating emotion have been shown to moderate this relationship, though little research accounts for differences based on the valence of the emotion being regulated.

Objective

To examine the independent moderating roles of positive and negative emotion dysregulation on the association between positive alcohol expectancies and alcohol use.

Methods

College students (N = 165, Mage = 20.48, SDage = 1.90; 66.1 % Female; 66.7 % White; 65.5 % non-Hispanic) who reported regular substance use (≥ 3 times in the past week) completed a one-time survey. Linear regression analyses with moderation were conducted.

Results

Correlational analyses suggested that positive alcohol expectancies, positive emotion dysregulation, and negative emotion dysregulation were positively associated with greater alcohol use. Linear regression analyses indicated that difficulties with positive emotion regulation moderated the relationship between positive alcohol expectancies and alcohol use. However, difficulties with negative emotion regulation did not moderate this relationship. College students who reported greater positive alcohol expectancies and concurrently greater difficulties with positive emotion regulation also report greater alcohol consumption, compared to those who reported greater positive alcohol expectancies and fewer difficulties regulating positive emotion.

Discussion

Difficulties with positive, not negative, emotion regulation may serve as a risk factor for hazardous alcohol use in college students. Findings may inform the modification of existing intervention programs across university counseling centers and other health sectors to promote the development of positive emotion regulation skills for individuals who endorse positive emotion regulation difficulties, thereby reducing hazardous alcohol use amid this high-risk developmental period.

Cannabis use across the menstrual cycle: The impact of negative affect and cannabis use motives

Women experience greater state negative affect (NA) and physical symptoms during the premenstrual and menstrual phases of the menstrual cycle. Although women use more cannabis during the premenstrual and menstrual phases, no known studies have tested whether this is due to the synergistic effects of heightened NA and using cannabis to cope with increased NA or physical symptoms. This study tested whether state NA interacts with cannabis motives to predict more frequent cannabis use during these phases. Normally cycling women who endorsed past-month cannabis use (N = 40) retrospectively reported NA, cannabis use, and motives for 65 days. Cannabis use was more frequent during the premenstrual (but not menstrual) phase, and cannabis use to manage physical pain/discomfort (physical motives) was greater in the menstrual (but not premenstrual) phase. There were significant interactions between phase, state NA (depression and anger, in separate models), and coping and physical motives. Among women with higher state depression, coping motives were associated with more frequent cannabis use in the ovulatory phase whereas among women with lower state depression, coping motives were associated with more frequent cannabis use in the premenstrual phase. Among women with lower (but not higher) state anger, coping motives were associated with greater cannabis use frequency in the premenstrual phase. Among women with higher state NA, physical motives were associated with more frequent cannabis use in the menstrual (but not premenstrual) phase. Findings support that state NA interacts with motives during high-risk phases and is differentially related to more frequent cannabis use, which has important clinical implications.

Examining concordance between emotion-dependent risk-taking in the laboratory and in the real-world

Risk-taking behavior is a leading cause of morbidity and mortality and is elevated among women experiencing intimate partner violence (IPV) and using substances. With the goal of advancing rigorous research on risk-taking behavior, this study examined the concordance of propensity for emotion-dependent risk-taking in the laboratory and emotion-dependent substance use and sexual behavior in the real world among women experiencing IPV and using substances. Women experiencing IPV were recruited from community establishments between 2018 and 2020 (N = 142; Mage = 40.63; 57.8% Person of Color). In the laboratory, participants underwent a randomly assigned negative, positive, or neutral emotion induction, following which they completed a behavioral measure of risk-taking propensity. Then, for the succeeding 30 days, they completed thrice daily surveys on emotion states and risk-taking behavior. Participants were more likely to drink alcohol, use cannabis, use illicit drugs, and have condomless sex during elevated (versus not elevated) negative and positive emotion states. However, participants did not exhibit greater risk-taking propensity in the laboratory in the context of negative and positive emotion states. Further, negative and positive emotion-dependent risk-taking propensity in the laboratory was not associated with negative and positive emotion-dependent risk-taking behavior in the real-world. Findings suggest the need for additional research that evaluates the utility of laboratory paradigms in the prediction of emotion-dependent risk-taking in the real-world.

Exploring the Role of Racial Microaggressions in the Association Between Depression Symptoms and Drug Use and Related Harm Among Women of Color Experiencing Intimate Partner Violence

Objective: Drug use and related harm among women of color who experience intimate partner violence (IPV) is a serious clinical concern. Depression symptoms have been identified as an important risk factor for the development of drug use and related harm among women of color with a history of IPV. The current study advances this research by examining the roles of distinct domains of racial microaggressions in the relation between depression symptoms and drug use and related harm in this population. Method: Participants were 103 women of color experiencing IPV (Mage = 40.39, 51% Black/African American). Results: Results indicated an indirect effect of depression symptoms on drug use and related harm via racial microaggression domains of Assumptions of Inferiority, Second-Class Citizen and Assumptions of Criminality, Microinvalidations, Exoticization and Assumptions of Similarity, and Environmental Microaggressions. Conclusions: Findings provide preliminary support for the role of racial microaggressions in the association between depression and drug use and related harm among women of color experiencing IPV.

Social Media Mindsets and Well-Being in Emerging Adults: A Serial Mediation of Facebook Addiction and Stress

BACKGROUND/OBJECTIVES

Emerging adults live in a time of rapid technological change, with social media playing a central role in their daily lives. While frequent use of social media is linked to reduced well-being, it also supports personal growth and the pursuit of individual goals. This study aims to identify the relationships between attitudes toward social media and psychological well-being in the context of the mediating roles of Facebook addiction and perceived stress in emerging adulthood.

METHODS

The study included 294 participants, with a mean age of 23.76 years (SD = 3.23). The following tools were used to measure the variables: the Social Media Mindsets Scale (translated by the authors), the Bergen Facebook Addiction Scale, the Perceived Stress Scale, the Psychological Well-Being Scale, and the Satisfaction with Life Scale. Correlation and mediation analyses were conducted.

RESULTS

The findings confirmed most of the assumptions. Attitudes toward social media were positively correlated with psychological well-being. Furthermore, Facebook addiction and perceived stress serve as serial mediators between attitudes toward social media and well-being.

CONCLUSIONS

Based on the results, practical interventions can be developed to prevent addictions and reinforce stress management, which will help young people maintain their well-being and mental health.

Examining the Receptivity to Tobacco Treatment Information for Individuals Living With Mental Illnesses: A Mixed Method Study

People living with mental illnesses (MI) have a specific need that requires tailored tobacco treatment (TT) information to be delivered in a desirable, appropriate, and acceptable manner to increase their receptivity. In this mixed-method study, we aimed to develop tailored TT pamphlets for people with MI. In Phase I, we explored perspectives on tailored TT information from mental health providers (MHPs) and individuals with MI. In Phase II, we assessed the desirability, applicability, and acceptability of the developed tailored TT pamphlets. Semistructured interviews were used to obtain qualitative and quantitative data from 16 MHPs and 13 individuals with MIs recruited from an inpatient psychiatric facility. Thematic analysis and descriptive statistics were used to synthesize the data. The study guides the development of effective approaches, presentations, and content to enhance TT engagement for people with MI. The proposed tailored TT pamphlets proved desirable, applicable, and acceptable for individuals with MI. We recommend developing tailored TT information for people with MI in collaboration with MHPs and the target audience. Clear, concise communication is crucial, ensuring desirability, applicability, and acceptability. Further research should identify effective approaches and evaluate tailored TT materials to enhance program effectiveness.

Associations between childhood polyvictimization, intimate partner violence victimization and substance use among college students

Objectives: Intimate partner violence (IPV) is associated with an elevated risk of substance use, but few studies have simultaneously examined other aspects of victimization history that may contribute to substance use. The current study examined the direct and moderating effects of childhood polyvictimization (i.e., multiple experiences of violence victimization before age 18) on the association between IPV subtypes (physical, sexual, psychological, and injury) and alcohol/drug use. Methods: A sample of 256 college students ages 18-25 (72% female, 68% white) completed a survey assessing past-year IPV, childhood polyvictimization, and past three-month substance use. Results: There were no direct or joint associations between IPV, childhood polyvictimization, and alcohol use. There were direct associations between psychological IPV, childhood polyvictimization, and drug use. No other forms of IPV were significantly associated with drug use. Conclusions: Results highlight unique direct associations between violence victimization and drug use risk compared to alcohol use risk in this context.

Appetitive and Aversive Motivation in Dysregulated Behaviors: A Meta-Analysis

Appetitive and aversive motivation are prominent in theories of dysregulated behaviors. The authors conducted a meta-analysis of the association between individual differences in appetitive and aversive motivation and several dysregulated behaviors (i.e., alcohol use, marijuana use, tobacco use, binge eating, aggression, gambling, and nonsuicidal self-injury). Alcohol use (r = .17, k = 141), marijuana use (r = .13, k = 23), aggression (r = .22, k = 52), and gambling (r = .08, k = 55) were all significantly positively related to appetitive motivation. Binge eating (r = .28, k = 34) and self-injury (r = .17, k = 10) were significantly positively related to aversive motivation. Effect sizes were similar to the median effect size in personality research. Together, these results provide some evidence that some dysregulated behaviors are more correlated with approach motivation, whereas others are more correlated with aversive motivation, which may indicate distinct etiological pathways.

The Robust Relation of Microaggressions with Alcohol-Related Problems Among Black Individuals Who Use Alcohol: the Role of Drinking to Cope with Negative Affect

BACKGROUND

Alcohol use is an important area of health disparities among Black individuals in the United States (US). The identification of psycho-sociocultural factors that play a role in alcohol-related problems among this population can inform culturally sensitive prevention and treatment efforts. Psycho-sociocultural models of alcohol misuse posit that some Black Americans may drink (and continue to drink despite drinking-related problems) to alleviate negative affect associated with experiencing race-based discrimination. Although there is a strong link between overt race-based discrimination and drinking outcomes, little research has tested whether more common, everyday race-based discrimination (microaggressions) is related and whether this association is attributable, in part, to drinking to cope with negative affect.

METHODS

Participants were 365 Black undergraduate current individuals who use alcohol who completed an online survey.

RESULTS

Microaggressions were significantly, positively correlated with alcohol-related problems, even after controlling for drinking, overt discrimination, non-racist life stressors, and relevant demographic variables. Microaggressions were indirectly related to alcohol-related problems via drinking to cope with negative affect (depression, anxiety).

CONCLUSIONS

Microaggressions are robustly associated with alcohol-related problems even after accounting for variance attributable to more overt discrimination and non-racist stressors among Black adults. Consistent with minority stress models, this relation may be due in part to drinking to cope with negative affect (depression, anxiety).

Association between parental phubbing and short-form video addiction: A moderated mediation analysis among Chinese adolescents

BACKGROUND

Short-form video applications have spread rapidly and gained popularity among adolescents for their interactivity, sociality, and personalization. However, excessive and uncontrolled use has also caused some adolescents to develop short-form video addiction (SFVA). Although parental phubbing has been shown to be a risk factor for SFVA in adolescents, its intermediate mechanisms, particularly the emotional mediation mechanisms, remain unclear. Therefore, this study aims to explore the relationships among parental phubbing, SFVA, symptoms of depression and anxiety, and neuroticism in adolescents.

METHODS

Adolescents aged 13-19 (N = 5785) were recruited from Shandong Province, China, as participants in 2023. Participants were asked to complete five self-report questionnaires, including the Parental Phubbing Behavior Questionnaire (PPBQ), Short-Form Video Addiction (SFVA) Scale, The Center for Epidemiological Studies Depression Scale (CESD20), Generalized Anxiety Disorder 7-item (GAD-7) Scale, and Chinese Big Five Personality Inventory (Brief Version) (CBF-PI-B).

RESULTS

The results indicate that the influence of parental phubbing on short-form video addiction among adolescents is mediated by symptoms of depression and anxiety. Additionally, neuroticism moderates the association between parental phubbing and symptoms of depression and anxiety.

LIMITATIONS

Cross-sectional design limits causal inferences. Reliance on self-report scales.

CONCLUSIONS

These findings contribute to a better understanding of the systemic impact mechanisms of negative family interactions on SFVA. Moreover, prevention and intervention strategies targeting high neuroticism and symptoms of depression and anxiety may help prevent the developmental pathway from parental phubbing to SFVA.

Smoking as a Marker of Comorbid Vulnerability Among Persons with Probable Posttraumatic Stress Disorder Who Engage in Hazardous Drinking

Background: Persons with posttraumatic stress disorder (PTSD) compared to those without evince high rates of hazardous drinking, or patterns of alcohol consumption that increase the risk for harmful consequences. One potential marker of vulnerability for PTSD-hazardous drinking comorbidity may be smoking behavior. Individuals with PTSD have a higher prevalence of smoking and smoke at higher rates. Smokers, compared to nonsmokers, are more apt to engage in hazardous alcohol use. Notably, there is a need to expand research on smoking in the context of PTSD and hazardous drinking to inform treatment of these morbidities. Objective: The present cross-sectional investigation sought to examine smoking status as a marker of risk among persons with probable PTSD who engage in hazardous drinking (N = 647; Mage = 38.90 years, SD = 10.71; 51.2% female). Results: Results indicated that trauma-exposed smokers, compared to non-smokers, evinced greater severity of PTSD symptoms, depression, emotion regulation difficulties, hazardous drinking, and substance use problems, with small effect sizes. No statistically significant group differences were found for anxiety symptom severity. Secondary analyses among only smokers supported an interrelation between cigarette dependence and each of the criterion variables that demonstrated statistically significant group differences. Specifically, cigarette dependence was statistically significantly and incrementally related to PTSD symptom severity, depression, emotion regulation difficulties, more severe hazardous drinking, and a greater degree of substance use problems. Conclusions: Overall, the current investigation found that smoking status among persons with probable PTSD who engaged in hazardous drinking was associated with numerous indicators of mental health and substance use vulnerability.

Young adult drinking during the COVID-19 pandemic: Examining the role of anxiety sensitivity, perceived stress, and drinking motives

Studies have shown that those high in anxiety were at increased risk for alcohol use during the COVID-19 pandemic. Tension reduction theory points to anxiety sensitivity (AS) as a potential risk factor. Drinking to cope may further increase this risk. During the pandemic, those high in AS may have experienced increased stress and drank to cope, which may have put them at risk for misusing alcohol. Objective: The current study tested the association between AS and alcohol outcomes, mediated by perceived stress and drinking motives, among young adults during the COVID-19 pandemic. Participants and Methods: Young adults (N = 143) self-reported on AS, perceived stress, drinking motives, and alcohol outcomes (i.e., use and problems). Results: A mediation analysis revealed that AS positively predicted alcohol problems, via coping motives, and positively predicted alcohol use, via perceived stress and enhancement/sociability motives. Conclusion: These results confirm AS-risk for young adult alcohol use during the pandemic and highlight perceived stress and drinking motives as mechanisms of risk.

Affective dynamics surrounding craving, non-heavy alcohol use and binge drinking in female patients with alcohol use disorder and controls: An experience sampling method study

BACKGROUND AND AIMS

Studies show that higher levels of positive affect (PA) and lower levels of negative affect (NA) are related to craving and alcohol consumption at a daily level in men, but little is known on these associations at a momentary level, and whether they are present in women. This study measured the dynamics of within-person NA and PA surrounding craving, non-heavy alcohol use and binge drinking in women with alcohol use disorder (AUD) and female controls without AUD.

METHODS

53 female patients with AUD and 75 female controls, all recruited in Belgium, were included in an experience sampling study where they reported on momentary NA, PA, craving and alcohol use in daily life over a period of 12 months. Assessments occurred eight times a day on Thursdays, Fridays and Saturdays in seven bursts of three weeks.

RESULTS

Within-person NA at a previous assessment (t-1) predicted craving at the current assessment (t0) in patients with AUD in a positive linear [β = 0.043; 95% confidence interval (CI) = 0.002, 0.057; P = 0.041] and quadratic fashion (β = 0.034; CI = 0.011, 0.057; P = 0.004). Within-person PA at t-1 predicted craving at t0 in patients with AUD with a positive quadratic relation (β = 0.042; CI = 0.08, 0.065; P < 0.001). Within-person NA at t-1 negatively predicted non-heavy alcohol use at t0 in a linear fashion in controls (β = -0.495; CI = -0.677, -0.312; P < 0.001) and patients with AUD (β = -0.276; CI = -0.421, -0.132; P < 0.001). Within-person PA at t-1 significantly predicted non-heavy alcohol use at t0 with a positive linear term (β = 0.470; CI = 0.329, 0.610; P < 0.001) in controls, but with a positive linear term (β = 0.399; CI = 0.260, 0.454; P < 0.001) and a positive quadratic term (β = 0.203; CI = 0.060, 0.347; P = 0.003) in patients with AUD. Within-person NA at t-1 predicted binge drinking at t0 in patients with AUD with a significant quadratic term (β = 0.236; CI = 0.060, 0.412; P = 0.008), but not for controls. Within-person PA at t-1 predicted binge drinking at t0 in patients with AUD with a significant quadratic term (β = 0.378; CI = 0.215, 0.542; P < 0.001), and this was also the case for controls (β = 0.487; CI = 0.158, 0.770; P < 0.001). Non-heavy alcohol use at t0 predicted lower levels of NA at t+1 in both patients with AUD (β = -0.161; SE = 0.044; CI = -0.248, 0.074; P = 0.001) and controls (β = -0.114; CI = -0.198, -0.029; P = 0.010). Non-heavy alcohol use at t0 also predicted higher levels of PA at t+1 in both patients with AUD (β = 0.181; CI = 0.088, 0.274; P < 0.001) and controls (β = 0.189; CI = 0.101, 0.278; P < 0.001).

CONCLUSIONS

The momentary relation between affect and craving or alcohol use seems to be non-linear in female patients with alcohol use disorder, whereby a worse mood predicts subsequent alcohol use, though more for binge drinking than for non-heavy alcohol use.

Effects of Trauma Cue Exposure and Posttraumatic Stress Disorder (PTSD) on Affect and Cannabis Craving in Cannabis Users With Trauma Histories: Use of Expressive Writing as an Online Cue-Reactivity Paradigm: Effets de l'exposition aux signaux traumatiques et du SSPT sur l'affect et le besoin de cannabis chez les consommateurs de cannabis ayant des antécédents de traumatismes : utilisation de l'écriture expressive comme paradigme de réactivité en ligne

OBJECTIVES

Posttraumatic stress disorder (PTSD) and cannabis use disorder (CUD) commonly co-occur. Conditioned associations between psychological trauma cues, distress, cannabis use, and desired relief outcomes may contribute to the comorbidity. These conditioned associations can be studied experimentally by manipulating trauma cue exposure in a cue-reactivity paradigm (CRP) and examining effects on affective and cognitive outcomes in participants with and without PTSD. However, traditional CRPs take place in-lab limiting recruitment/power. We aimed to examine the effects of CRP condition (trauma and neutral) and PTSD group (likely PTSD+ and PTSD-) on affective and craving outcomes using a stand-alone online expressive writing CRP.

METHODS

Participants (n = 202; 43.6% male; Mage = 42.94 years, SD = 14.71) with psychological trauma histories and past-month cannabis use completed a measure of PTSD symptoms (PTSD Checklist-5 for DSM-5 [PCL-5]) and were randomized to complete either a trauma or neutral expressive writing task. Then they completed validated measures of affect (Positive and Negative Affect Schedule-Short Form [PANAS-SF]) and cannabis craving (Marijuana Craving Questionnaire-Short Form [MCQ-SF]).

RESULTS

Linear mixed models tested the hypothesized main and interactive effects of CRP condition (trauma and neutral) and PTSD group (likely PTSD+ and PTSD-) on negative and positive affect (PANAS-SF) and cannabis craving dimensions (MCQ-SF). The hypothesized main effects of trauma versus neutral expressive writing were found for negative affect and the expectancy dimension of cannabis craving and of PTSD group for negative affect and all cannabis craving dimensions; no interactions were observed.

CONCLUSIONS

Expressive writing appears a useful online CRP. Interventions focused on reducing negative affect and expectancy craving to trauma cues may prevent/treat CUD among cannabis users with PTSD.

Commentary With Study Protocol: Implementation and Effectiveness of Mindfulness-Oriented Recovery Enhancement (MORE) as an Adjunct to Methadone Treatment for Opioid Use Disorder (IMPOWR-MORE)

Traditional methadone treatment (MT) for opioid use disorder (OUD) fails to systematically address the physical pain, emotion dysregulation, and reward processing deficits that co-occur with OUD, and novel interventions that address these issues are needed to improve MT outcomes. Mindfulness-Oriented Recovery Enhancement (MORE) remediates the hedonic dysregulation in brain reward systems that is associated with OUD. Our pilot and phase 2 randomized controlled trials of MORE were the first to demonstrate MORE's feasibility, acceptability, and efficacy as delivered in MT clinics; MORE significantly reduced drug use (eg, benzodiazepines, barbiturates, cocaine, marijuana, opioids, and other drugs), craving, depression, anxiety, and pain among people with OUD. However, uptake of novel, efficacious interventions like MORE may be slow in MT because time and resources are often limited. Therefore, to best address potential implementation issues and to optimize future MORE implementation and dissemination, in this study, we will utilize a Type 2, Hybrid Implementation-Effectiveness study design. We will not only evaluate MORE's effectiveness but also assess barriers and facilitators to integrating MORE into MT. MT clinicians will receive training in (1) a higher intensity MORE implementation strategy consisting of training in the full MORE treatment manual or (2) a minimal intensity implementation strategy consisting of a simple, scripted mindfulness practice (SMP) extracted from the MORE treatment manual with minimal training. We aim to: (1) using a Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework, examine barriers and facilitators to implementation of MORE and SMP in MT, and evaluate strategies for optimizing training, fidelity, and engagement, (2) optimize existing MORE and SMP training and implementation toolkits, including adaptable resources that can accelerate the translation of evidence into practice, and (3) compared to usual MT, evaluate the relative effectiveness of MORE plus MT or SMP plus MT (N = 450).

Development and Initial Validation of a Momentary Cannabis Craving Scale Within a Homogeneous Sample of U.S. Emerging Adults

Given the popularity and ease of single-item craving assessments, we developed a multi-item measure and compared it to common single-item assessments in an ecological momentary assessment (EMA) context. Two weeks of EMA data were collected from 48 emerging adults (56.25% female, 85.42% White) who frequently used cannabis. Eight craving items were administered, and multilevel factor analyses were used to identify the best fitting model. The resulting scale's factors represented purposefulness/general desire and emotionality/negative affect craving. Convergent validity was examined using measures of craving, cannabis use disorder symptoms, frequency of use, cannabis cue reactivity, cannabis use, negative affect, and impulsivity. The scale factors were associated with cue-reactivity craving, negative affect, impulsivity, and subfactors of existing craving measures. For researchers interested in using a single item to capture craving, one item performed particularly well. However, the new scale may provide a more nuanced assessment of mechanisms underlying craving.

Predictors of substance use during treatment for addiction: A network analysis of ecological momentary assessment data

BACKGROUND AND AIMS

Ecological momentary assessment (EMA) studies have previously demonstrated a prospective influence of craving on substance use in the following hours. Conceptualizing substance use as a dynamic system of causal elements could provide valuable insights into the interaction of craving with other symptoms in the process of relapse. The aim of this study was to improve the understanding of these daily life dynamic inter-relationships by applying dynamic networks analyses to EMA data sets.

DESIGN, SETTING AND PARTICIPANTS

Secondary analyses were conducted on time-series data from two 2-week EMA studies. Data were collected in French outpatient addiction treatment centres. A total of 211 outpatients beginning treatment for alcohol, tobacco, cannabis, stimulants and opiate addiction took part.

MEASUREMENTS

Using mobile technologies, participants were questioned four times per day relative to substance use, craving, exposure to cues, mood, self-efficacy and pharmacological addiction treatment use. Multi-level vector auto-regression models were used to explore contemporaneous, temporal and between-subjects networks.

FINDINGS

Among the 8260 daily evaluations, the temporal network model, which depicts the lagged associations of symptoms within participants, demonstrated a unidirectional association between craving intensity at one time (T0) and primary substance use at the next assessment (T1, r = 0.1), after controlling for the effect of all other variables. A greater self-efficacy at T0 was associated with fewer cues (r = -0.04), less craving (r = -0.1) and less substance use at T1 (r = -0.07), and craving presented a negative feedback loop with self-efficacy (r = -0.09).

CONCLUSIONS

Dynamic network analyses showed that, among outpatients beginning treatment for addiction, high craving, together with low self-efficacy, appear to predict substance use more strongly than low mood or high exposure to cues.

Developing an extended process model of emotion regulation in PTSD

Emotion regulation is a topic of growing interest in the field of post-traumatic stress disorder (PTSD). Despite the field's concentrated efforts in this area, the research has not matched advancements in the general emotion regulation literature, which have proposed more holistic models to understanding to how individuals identify and respond to emotions. In looking at emotion regulation in PTSD, this paper reviews the current state of the literature using the Extended Process Model proposed by Gross (2015). Considering emotion perception, beliefs, emotion regulation strategies (in terms of choice, flexibility of use, and repertoire of strategies available), and tactics, it discusses how these constructs help us understand the pathogenesis of PTSD and identifies areas in need of further research, including assessing the role of culture and improving measurement of emotion regulation constructs. Clinical implications of the emotion regulation literature for PTSD treatment are discussed.

Addiction Memory, Family Functioning, and Depression in Illicit Drug Users: Self-Esteem as a Mediator

Depression is a common issue among illicit drug users. However, the interaction between addiction memory, family functioning, and depressive symptoms remains insufficiently examined. This study investigates the relationship between addiction memory, family functioning, and depressive symptoms, with self-esteem serving as a mediator. A random sample of 600 illicit drug users from Hubei, China, was evaluated using the Addiction Memory Intensity Scale (AMIS), Family APGAR Index, Patient Health Questionnaire (PHQ-9), and Rosenberg Self-Esteem Scale (RSES). A factorial algorithm was used to parcel the AMIS, PHQ-9, and RSES items, and structural equation modeling was applied to examine the mediation effect. The model fit the data well (χ2/df = 2.248, CFI = 0.956, NNFI = 0.966, RMSEA = 0.046, SRMR = 0.040), with significant path coefficients (p < 0.05). Addiction memory was positively correlated with depression (β = 0.195, p < 0.001), while family functioning negatively correlated with depression (β = -0.113, p = 0.008). Both addiction memory and family functioning indirectly influenced depression through self-esteem, with mediating effects equal to 1.154 (95% CI: 0.106 to 0.209) and -0.097 (95% CI: -0.154 to -0.047). These findings suggest that interventions targeting addiction memory and family functioning may alleviate depressive symptoms by improving self-esteem among illicit drug users.

Attentional bias in tobacco use disorder using eye tracking: A systematic review

Background

Attentional bias, defined as the disproportionate attentional allocation towards drug-related stimuli, is well-demonstrated in substance use disorders. However, studies investigating attentional bias in tobacco use disorder have revealed inconclusive findings. In recent years, eye-tracking technology has emerged as an innovative technique for exploring attentional bias. This systematic review aims to provide a comprehensive overview of eye-tracking studies examining attentional bias in tobacco use disorder.

Methods

Using PRISMA guidelines, 18 papers that assessed attentional bias using eye-tracking technology among people who smoke cigarettes were extracted from the following databases: PsychINFO, MEDLINE, and EMBASE. Search terms included "attentional bias", "tobacco use disorder", and "eye tracking" and their respective subject headings and synonyms. Selected papers were assessed for methodological quality using a standardized procedure. Selected studies reviewed were categorized into studies making comparisons between 1) people who smoke and people who do not smoke and 2) between smoking-related cues and neutral cues among people who smoke.

Results

Overall, most studies showed that people who smoke had significantly greater attentional bias to smoking-related cues, as indexed by greater dwell times and fixation counts. Although findings using measures of early orienting biases were mixed, people who smoke displayed a tendency to initially shift attention to smoking-related cues more frequently than neutral cues.

Conclusions

While methodological inconsistencies across studies preclude any definitive conclusions, findings suggest that maintained attention may be a more precise reflection of the specific attentional processes influenced by incentive salience. Suggestions for future research include establishing methodological standards for future eye-tracking studies.

Motivational interviewing-based interventions with patients with comorbid anxiety and substance use disorders

Individuals with substance misuse and substance use disorder (SUD) experience especially high rates of elevated anxiety, including anxiety disorders, and the co-occurrence of these conditions is related to worse treatment outcomes. Given that these patients may have little motivation to change their substance misuse if they use substances to cope with their chronically elevated anxiety, interventions that include components that target motivation may be especially useful. Thus, this paper reviews the recent extant literature on treatments developed specifically for these high-risk patients that include motivational interviewing (MI) techniques to increase motivation for behavioral change. Results indicate that two modalities have been tested - in-person therapies and online interventions. The majority use MI techniques to change substance use and some to change anxiety-related behaviors. The majority also incorporate cognitive-behavioral skills to manage substance use and anxiety. Data indicate that MI techniques can be administered in-person and online to decrease substance misuse and anxiety among patients with elevated anxiety and substance misuse.

Posttraumatic Stress Disorder and Substance Use Disorder Screening, Assessment, and Treatment

PURPOSE OF REVIEW

We review prevalence, etiology, impact on treatment, and best practices for treatment of posttraumatic stress disorder (PTSD) in a substance use disorder (SUD) treatment setting. Recommendations are given related to screening, assessment, and symptom monitoring.

RECENT FINDINGS

PTSD and SUDs are highly comorbid. This comorbidity is associated with higher acuity, more difficulty completing treatment, and worse prognosis. Integrated treatment is recommended, and trauma-focused psychotherapies combined with pharmacotherapy show particular promise. PTSD is highly prevalent in substance using samples, negatively impacting treatment course and worsening prognosis. This comorbidity has been explained by a variety of models, with self-medication having garnered the most support. Trauma-focused psychotherapies combined with pharmacotherapy demonstrate the most efficacy and are recommended when treating co-occurring SUDs and PTSD. Specifically, prolonged exposure (PE), concurrent treatment of PTSD and SUDs using PE (COPE), and cognitive processing therapy (CPT) have been seen as promising trauma-focused treatments. Investigations into ways to best augment therapy are also underway, both through treatment format and neuromodulation. Several recommendations are given.

The symptom network of internet gaming addiction, depression, and anxiety among children and adolescents

Internet gaming addiction (IGA), depression, and anxiety are significant issues among children and adolescents, with substantial social implications. Understanding the specific characteristics of this relationship is crucial for developing effective prevention and intervention strategies. The present study employed network analysis to explore the symptom network of IGA, depression, and anxiety among 1,548 Chinese children and adolescents. The results showed that the core symptoms of IGA among children and adolescents were "tolerance", "withdrawal", and "conflict". There was no significant gender difference in the structure, global strength, and core symptoms of IGA. Although there were no significant differences in the structure of the symptom network of IGA among children and adolescents of different ages, there were significant differences in global strength and some core symptoms ("conflict"). The core symptoms of the comorbidity of IGA, depression, and anxiety in children and adolescents included "feeling downhearted and blue", "breathing difficulty", "difficult to work up the initiative to do things", and "withdrawal". The comorbidity network did not show significant gender and age differences in network structure, but there were significant gender differences in global strength. Furthermore, there were significant gender and age differences in some core symptoms. The social impact of these findings is profound, highlighting the need for targeted interventions in schools and communities to address IGA and its comorbidities. Our results also suggest that interventions should be tailored to consider gender and age differences to maximize effectiveness.

Sexism and Cannabis-Related Problems Among Women in the U.S.: The Role of Negative Affect and Coping-Motivated Cannabis Use

BACKGROUND

Although previous studies have highlighted the detrimental impact of sexism on other substance use and use-related outcomes among women, limited empirical attention has tested whether sexism is related to worse cannabis-related outcomes. It may be that women use cannabis to cope with negative affect related to experiencing sexism, and thus continue to use despite cannabis-related problems. However, no known studies have tested this hypothesis.

OBJECTIVES

We tested whether experiencing sexism was related to more cannabis use-related problems via the serial effects of negative affect (anxiety, depression) and coping-motivated cannabis use among 304 women who endorsed current (past three-month) cannabis use.

RESULTS

Sexism was significantly positively related to coping-motivated-cannabis use and use-related problems. Sexism was indirectly related to cannabis problems via the serial effects of anxiety and coping motives and via the serial effects of depression and coping motives, but not via the indirect effects of anxiety, depression, or coping motives alone.

CONCLUSIONS

Findings suggest that women may use cannabis to cope with sexism-related negative affect, and thus continue to use despite experiencing greater cannabis problems. These results may have important clinical implications and emphasize the need for greater gender-responsive approaches in prevention and intervention efforts for women who use cannabis.

Large-scale characterization of cocaine addiction-like behaviors reveals that escalation of intake, aversion-resistant responding, and breaking-points are highly correlated measures of the same construct

Addiction is commonly characterized by escalation of drug intake, compulsive drug seeking, and continued use despite harmful consequences. However, the factors contributing to the transition from moderate drug use to these problematic patterns remain unclear, particularly regarding the role of sex. Many preclinical studies have been limited by small sample sizes, low genetic diversity, and restricted drug access, making it challenging to model significant levels of intoxication or dependence and translate findings to humans. To address these limitations, we characterized addiction-like behaviors in a large sample of >500 outbred heterogeneous stock (HS) rats using an extended cocaine self-administration paradigm (6 hr/daily). We analyzed individual differences in escalation of intake, progressive ratio (PR) responding, continued use despite adverse consequences (contingent foot shocks), and irritability-like behavior during withdrawal. Principal component analysis showed that escalation of intake, progressive ratio responding, and continued use despite adverse consequences loaded onto a single factor that was distinct from irritability-like behaviors. Categorizing rats into resilient, mild, moderate, and severe addiction-like phenotypes showed that females exhibited higher addiction-like behaviors, with a lower proportion of resilient individuals compared to males. These findings suggest that, in genetically diverse rats with extended drug access, escalation of intake, continued use despite adverse consequences, and PR responding are highly correlated measures of a shared underlying construct. Furthermore, our results highlight sex differences in resilience to addiction-like behaviors.

Emotion Regulation Can Effectively Improve Decision-Making Behaviors of Individuals Who Use Methamphetamine

PURPOSE

Negative emotions can cause people to make irrational decisions, and decision-making disorders may lead individuals who use methamphetamine (meth) to relapse. Therefore, the current study was performed to investigate whether emotion regulation (ER) can improve negative emotions and thus improve decision-making behavior of individuals who use meth.

METHOD

Based on the Iowa Gambling Task, a three-factor mixed experimental design was used to examine the effects of cognitive reappraisal and expressive suppression strategies on negative emotions and decision-making behaviors of 157 individuals who use meth.

RESULTS

Cognitive reappraisal and expressive suppression were effective in reducing participants' negative emotions and improving decision-making behaviors. Specifically, two types of ER strategies were effective in improving decision-making abilities of participants with negative emotional distress, and cognitive reappraisal was more effective than expressive suppression.

CONCLUSION

Regarding cognitive reappraisal, female participants showed better decision-making behavior than males, which predicts that females who use meth might be more adept at using cognitive reappraisal. This finding suggests that mental health providers should aid substance users in managing their negative emotions and also pay attention to gender differences during the nursing process.

Emotional regulation in Gaming Disorder: A systematic review

BACKGROUND AND OBJECTIVES

Problematic video game use is a source of concern. In addictions, difficulties with emotional regulation have become an important variable of interest. However, their study in relation to problematic video game use remains insufficient.

METHODS

A systematic review was conducted following PRISMA 2020 guidelines; 322 studies were screened, resulting in a final sample of k = 18 studies. The methodological quality of these studies was rated as moderate according to the McMaster Critical Review Form for Quantitative studies (CRF-Q).

RESULTS

There is evidence of relationship between different facets of emotional regulation and the presence of problematic video game use. Particularly, video games serve as escape strategy for suppressing emotional expression. There is no consensus regarding the nature of the relationship between emotional regulation, psychopathology, and problematic video game use, with various proposals suggesting moderation and mediation. There is also no consensus regarding the mediation of gender in the relationship between emotional dysregulation and problematic video game use. The level of certainty regarding the validity of the results was moderate.

DISCUSSION AND CONCLUSIONS

Emotional dysregulation plays a role in problematic video game use, especially through strategies as emotional suppression, and lack of abilities to understand and control emotions. It is important to consider emotional regulation as a potential target for research and intervention in clinical populations.

SCIENTIFIC SIGNIFICANCE

We review the largest sample of papers on problem gaming and emotion regulation to date. Our results highlight the importance of emotion regulation and, specially, emotional suppression, or negative escapism, on problematic video game use.

Behavioral activation for veterans with co-occurring alcohol use disorder and posttraumatic stress disorder: Basis and methodology for a pilot randomized controlled trial

BACKGROUND

Nearly 2 million U.S. veterans live with co-occurring alcohol use disorder and posttraumatic stress disorder (AUD/PTSD). Extant AUD/PTSD treatments emphasize symptom reduction, sometimes overlooking psychosocial functioning improvements, and have dropout rates as high as 50 %. Additionally, current approaches to measuring psychosocial functioning are limited to self-report. This study protocol describes a 1:1 parallel, two-arm, pilot randomized controlled trial comparing Behavioral Activation (BA) psychotherapy to Relapse Prevention (RP) psychotherapy for veterans with AUD/PTSD.

METHODS

Forty-six veterans with AUD/PTSD will be block-randomized to eight weekly, virtual, hour-long individual sessions of BA or RP. Clinical interview, self-report, and geospatial assessments will be administered at pre- and post-treatment. Select outcome and exploratory measures will be administered during treatment. Analyses will focus on trial feasibility, BA acceptability, and preliminary efficacy. Geospatial analyses will explore whether pre- to post-treatment changes in geospatial movement can be used to objectively measure treatment response. The study site and an independent Data and Safety Monitoring Board will monitor trial progress, safety, and quality. De-identified data from consenting participants will be submitted to a sponsor-designated data repository.

CONCLUSION

If successful, this trial could help to provide veterans with AUD/PTSD with a more acceptable treatment option. Positive findings would also lay groundwork for testing BA in civilians with AUD/PTSD. Finally, by incorporating novel geospatial methods and technologies, this study could potentially yield a new approach to objectively measuring AUD/PTSD recovery that could be used in other clinical trials. This study was registered in ClinicalTrials.gov (NCT06249386).

The relations of difficulties in emotion regulation and distress intolerance with cannabis problems: The role of protective behavioral strategies underutilization

INTRODUCTION

Difficulties with emotion regulation and distress tolerance are related to more cannabis problems, yet little research has identified why this is the case. Cannabis-related protective behavioral strategies (PBS; behaviors used to mitigate cannabis related problems) are related to less cannabis consumption and related problems. Potentially, these individuals may use cannabis to alleviate the distress and/or in an attempt to regulate their emotions. Thus, the present study aimed to examine the mediational role of PBS on the relations of emotion dysregulation and distress intolerance with cannabis problems.

METHODS

Undergraduate students who endorsed past-month cannabis use (N = 339, Mage = 19.33, SDage = 1.37; 77.9 % female) at a southern United States university completed a survey online via Qualtrics.

RESULTS

More emotion dysregulation and less distress tolerance predicted less PBS use and more cannabis problems, but not cannabis use frequency. After statistically controlling for sex, the relation of each transdiagnostic factor with cannabis problems occurred indirectly via the relations of less PBS use and greater cannabis use frequency CONCLUSIONS: The present study supports previous claims that emotion dysregulation and distress intolerance are related to more cannabis problems. Additionally, results suggest that individuals with high levels of these problems underutilize PBS which, in turn, is associated with more frequent cannabis use and use-related problems. Clinical implications are discussed.

Emotion dysregulation in participants with substance use disorders: A metacognitive perspective

BACKGROUND

Using the metacognitive model of emotion dysregulation as a basis, this study explored whether, among participants with substance use disorders (SUDs), metacognitive beliefs and repetitive negative thinking were associated with emotion dysregulation.

METHODS

127 participants with SUDs and 127 controls without SUDs were recruited. Emotion dysregulation, metacognitive beliefs, rumination, worry, anxiety, and depression were assessed. t-tests, Mann-Whitney tests, logistic regression, correlation, and hierarchal regression analyses were run.

RESULTS

Participants with SUDs reported significantly higher levels of emotion dysregulation, positive beliefs about worry, beliefs about the need to control thoughts, rumination, and worry, compared to controls without SUDs. Among participants with SUDs negative beliefs about thoughts concerning uncontrollability and danger, cognitive confidence, beliefs about the need to control thoughts, rumination, and worry were significantly associated with an increase of emotion dysregulation.

LIMITATIONS

The cross-sectional design.

CONCLUSION

Emotion dysregulation, metacognitive beliefs, and repetitive negative thinking may contribute to increase the risk of substance use. Among participants with SUDs emotion dysregulation is associated with the tendency to endorse dysfunctional metacognitive beliefs and report repetitive negative thinking. Metacognitive beliefs and repetitive negative thinking could be a suitable therapeutic target to reduce emotion dysregulation among participants with SUDs.

A systematic review and meta-analysis of psychosocial interventions for persons with comorbid anxiety and substance use disorders

BACKGROUND & AIMS

Anxiety and substance use disorders are highly comorbid and represent two of the leading causes of disease burden globally. Psychosocial interventions are important treatment options for people with co-occurring anxiety and substance use (A-SUD). To date, few reviews have assessed the efficacy of psychosocial treatments for patients with A-SUD. This systematic review and meta-analysis aims to synthesize this literature and assess the efficacy of psychosocial interventions among patients with A-SUD.

METHODS

We searched all relevant records published until March 2023 in Medline, EMBASE, PsycINFO, CINAHL and Google Scholar. Two authors extracted and reconciled relevant data and assessed risk of bias. Random effects models were used to calculate effect sizes using Hedges' g for post treatment and follow-up time points. Main outcomes of the review were anxiety, alcohol use, and use of other substances. We examined effects on depression as a secondary outcome since it commonly co-occurs with A-SUD.

RESULTS

Psychosocial interventions for co-occurring A-SUD showed moderate effects on anxiety (g = 0.44), alcohol (Hedges' g = 0.29), and other substance use (g = 0.38) at post intervention. Large effects were observed on depression (g = 0.88) at post intervention with high heterogeneity. These effects were maintained at follow-up for anxiety (Hedges' g = 0.38), other substances (g = 0.44), and depression (g = 0.50). Moderation analyses for demographic factors, intervention characteristics, community level factors, anxiety reduction, and alcohol use reduction, were non-significant.

CONCLUSIONS

The current meta-analysis investigated the effects of psychosocial interventions on patients with anxiety and co-occurring SUD. The analyses indicated promising moderate-sized effects of treatment on anxiety, alcohol, all other drug use, and depression. The findings point to important avenues for psychosocial treatment while highlighting critical gaps in knowledge to be addressed in future research.

The day-level effects of recovery community center attendance on indicators of recovery wellbeing and risk

BACKGROUND

Recovery community centers (RCCs) are a relatively new resource in the recovery support landscape aimed at building their members' recovery capital. In recent years, interest in the value of RCCs has grown, however, no studies have used within-person methods to consider how RCCs may impact the day-to-day lives of their attendees. Using within-person data drawn from members of RCCs, this study examined how visiting RCCs was associated with several same-day indicators of recovery wellbeing and risk: daily sense of meaningfulness, recovery identity, negative affect, and positive affect.

METHODS

Participants were 94 visitors of six RCCs in western Pennsylvania. Daily diary methods collected 10 nightly reports of daily RCC attendance and end-of-day meaningfulness, recovery identity, negative affect, and positive affect. Multilevel modeling accounted for nesting in the intensive longitudinal data. In independent models, the study regressed meaningfulness, recovery identity, negative affect, and positive affect onto day- and person-level RCC attendance.

RESULTS

Within-person associations between RCC attendance and meaningfulness (b = 6.96, SE = 1.66, p < .001), recovery identity (b = 4.75, SE = 1.08, p < .001), and PA (b = 3.82, SE = 1.45, p < .01) were significant, although NA was not (b = -2.41, SE = 1.34, n.s.). All day- by person-level RCC attendance interactions (in preliminary models) and between-person associations were non-significant across recovery outcomes.

CONCLUSIONS

The results indicated that on days participants visited RCCs, they reported significantly higher levels of meaningfulness, recovery identity, and positive affect, although negative affect levels did not significantly differ. Also, those who attended RCCs more frequently did not generally report different levels of recovery wellbeing and risk. Taken together, results suggest visiting RCCs works on a daily basis to support interpersonal processes related to positive recovery outcomes. That RCC visits do not appear to reduce negative affect suggests that additional programs may be needed to address negative affect. The within-person design provided insight into the dynamic processes that contribute to the intrapersonal states that support recovery and a practical approach to examining whether and how RCCs might support recovery. By using individuals as their own controls, the study design provided strong counterfactual inference.

The dual nature of working memory deficits: methamphetamine abusers have more impaired social working memory capacity than canonical working memory capacity

Social working memory (WM) temporarily retains and manipulates various aspects of social information. Extensive research has highlighted impaired social cognitive functions in individuals with substance addiction. However, the specific deficit in social WM within this population remains notably understudied. Bridging this gap, we investigated social WM capacity using biological motion (BM) stimuli in methamphetamine (MA) abusers compared to an inmate control group, alongside contrasting these findings with their canonical WM deficits. Across two studies, we recruited female MA abusers (N = 80) undergoing post-isolation rehabilitation within a mandatory confinement circumstance. To ensure a pertinent comparison, we recruited female inmates (N = 80) subjected to comparable confinement. Results show substantial BM WM impairment in MA abusers, yet non-BM WM remains mostly intact. These findings highlight a pronounced social WM deficit in MA abusers, surpassing their canonical WM deficit relative to inmate controls. This suggests a distinct dissociation between social and canonical WM processing.

Association between psychological pain and suicidal ideation among men with substance use disorder: a moderated mediation model

Previous studies have found that people with substance use disorder are associated with significantly higher odds of suicidal ideation than the general population. Psychological pain and emotional regulation are considered protective factors for suicidal ideation, but the interaction process is not clear. In this study, we investigated the effects of psychological pain on suicidal ideation and constructed a moderated mediation model. 445 men with substance use disorder in China were recruited to complete the Chinese version of the Psychological Pain Scale, Regulatory Emotional Self-efficacy Scale, Suicidal Ideation Scale, and Intolerance of Uncertainty Scale. The results demonstrated that psychological pain significantly and positively predicted suicidal ideation among people with substance use disorder, and that regulatory emotional self-efficacy played a mediating role between psychological pain and suicidal ideation. Intolerance of uncertainty moderated the top and bottom halves of the intermediate process paths. This study suggests that intolerance of uncertainty and regulatory emotional self-efficacy can be improved by interventions among people with substance use disorder, which in turn can reduce their suicidal ideation and improve quality of life.

Exploring the interplay of abstinence self-efficacy, locus of control, and perceived social support in substance use disorder recovery

INTRODUCTION

Substance use disorder (SUD) poses a significant public health challenge globally, with substantial impacts on physical and social well-being. This study investigates the interplay between abstinence self-efficacy (ASE), locus of control (LOC), perceived social support (PSS), and various socio-demographic and psychosocial factors among individuals undergoing SUD rehabilitation.

METHODS

Researchers obtained permission from drug rehabilitation centers in Assam, India, and conducted orientation programs for prospective participants. A total of 144 participants, aged 18-65 years, predominantly from rural areas participated in the study. Data was collected through one-to-one interviews, covering socio-demographic history, drug abuse, and administering scales for ASE, LOC and PSS. Collected data underwent digitization and subsequent descriptive and inferential statistical analyses.

RESULTS

Significant associations were found between ASE and socio-demographic variables, family dynamics, and drug use history, highlighting the importance of considering these factors in SUD rehabilitation. Disturbed family relationships were linked to diminished ASE and higher risk of relapse, emphasizing the role of family support in recovery. Additionally, a negative correlation was observed between ASE and LOC, suggesting that individuals with higher ASE tend to have a more internal locus of control, which positively influences recovery outcomes. Moreover, positive correlations were found between ASE and PSS, particularly from family members, underscoring the importance of social support in fostering recovery. Regression analysis further elucidated the relationships between ASE, LOC, and PSS, emphasizing the predictive value of LOC and the impact of family support on ASE.

CONCLUSION

Findings of this study have several implications for developing targeted interventions aimed at strengthening ASE, promoting internal locus of control, and enhancing social support systems.

Beyond the mean: examining associations between intraindividual variability in posttraumatic stress disorder symptoms and posttrauma reckless behaviors

BACKGROUND/OBJECTIVES

Posttrauma reckless behaviors have been linked to the onset and exacerbation of posttraumatic stress disorder (PTSD) symptoms. However, PTSD symptoms fluctuate across time, triggered by environmental stimuli in daily life, referred to as (intraindividual) variability in PTSD symptoms.

DESIGN

We utilized experience sampling methods to investigate associations between engagement in posttrauma reckless behaviors and variability in PTSD symptoms and the moderating role of emotion dysregulation in this association.

METHODS

Data from 166 trauma-exposed university students (Mage = 21.43 ± 5.07, 85.4% women) were collected between January 2019 to August 2020. Participants completed baseline and follow-up surveys to assess engagement in posttrauma reckless behaviors and daily surveys (10-days) to assess variability in PTSD symptoms. Results. Analyzes indicated greater baseline engagement in posttrauma reckless behaviors was associated with greater 10-day variability in PTSD symptoms (β = 0.23, p = .031), and baseline emotion dysregulation moderated this association (β = -0.33, p = .003). Additionally, greater 10-day variability in PTSD symptoms was associated with greater follow-up engagement in posttrauma reckless behaviors (β = 0.14, p = .045).

CONCLUSIONS

Findings substantiate the interplay between engagement in posttrauma reckless behaviors and daily fluctuations in PTSD symptoms and support therapeutically targeting both engagement in posttrauma reckless behaviors and emotion dysregulation to impact PTSD symptoms.

Effects of medical cannabis use on physical and psychiatric symptoms across the day among older adults

INTRODUCTION

Older adults are increasingly using medical cannabis (MC). It is unclear if therapeutic effects increase problematic use patterns. The current study addresses this issue by examining symptom trajectories across the day and using trajectories to predict problematic use.

METHODS

One-hundred six older adults (age range 55-74) who endorsed medical conditions approved for treatment using MC were recruited online. Participants received six text messages/day to assess momentary symptoms for 15 days.

RESULTS

Participants provided 5,156 momentary assessments across 1,106 use days. Symptom trajectories were examined across the day. There was a decline in all symptoms following use. Negative affect, pain, and nausea evinced momentary negative reinforcement associations with cannabis intoxication. Momentary negative reinforcement was associated with adverse cannabis outcomes. Declines in post-use trauma symptoms and momentary negative reinforcement effects for negative affect were both associated with cannabis use disorder symptoms.

DISCUSSION

These data suggest that MC may be effective in reducing common symptom clusters. However, the negative reinforcing effect (i.e., the link between use and symptom relief at the event level) may complicate the therapeutic nature (i.e., symptom reduction). Identifying interventions to maximize benefits while minimizing costs may increase the efficacy and safety of MC in older adults.

An examination of cannabis use motives among couples with intimate partner violence and alcohol use disorder

BACKGROUND AND OBJECTIVES

Cannabis use is highly prevalent among individuals with a history of intimate partner violence (IPV) and among people who drink alcohol. Motives for cannabis use are important correlates of consumption and problem severity. However, no research has examined cannabis use motives among couples with IPV. The goals of the study were to examine (1) the associations between a person and their partner's cannabis use motives; and (2) examine the extent to which each partners' cannabis use motives are related to their own and their partner's cannabis consumption.

METHODS

Participants were 100 couples (n = 92 different-sex couples, n = 8 same-sex couples) who reported physical IPV in their current relationship.

RESULTS

Certain cannabis motives (coping and conformity) and behaviors (cannabis use frequency, quantity and drug-related problems) were positively associated between intimate partners. One's own higher coping motives were associated with greater frequency of cannabis consumption; higher conformity motives were associated with less quantity of consumption; higher social motives were associated with greater quantity of cannabis consumption; and one's partner's social motives were associated with less quantity of cannabis consumption. DISCUSSION AND CONCLUSIONS: Findings suggest that couples report similar motives for cannabis use, and that one's own and their partner's motives may differentially influence frequency and quantity of use.

SCIENTIFIC SIGNIFICANCE

This study provides novel information on congruency between cannabis use motives and behaviors between intimate partners, as well as how both an individual and their partner's motives for use can influence an individual's cannabis use behaviors.

What Is the Role of Affective Cognition in Trauma and Posttraumatic-Stress-Disorder-Related Drinking? A Systematic Review

Trauma and posttraumatic stress disorder (TR/PTSD) are implicated in deleterious alcohol outcomes, yet the processes that undergird these associations remain elusive. Affective (i.e., emotionally laden) cognitions may play key roles in TR/PTSD-related drinking that could inform prevention and intervention. The present review synthesized extant literature (k = 58) on affective cognitions and their role in negative and positive reinforcement TR/PTSD-related drinking, including alcohol-specific (e.g., drinking motives, alcohol expectancies) and non-alcohol-specific (e.g., emotion regulation cognitions, perception and attentional biases) cognitions. Findings generally supported the importance of alcohol-specific cognitions in negative more so than positive reinforcement drinking. Non-alcohol-specific affective cognitions were considerably less researched. Several gaps in the knowledge base emerged; studies were overwhelmingly cross-sectional, conducted mainly within homogenous college samples, and often did not disaggregate effects of trauma exposure from those of PTSD. Future research is needed to address these gaps to optimally inform clinical efforts to reduce TR/PTSD-related drinking risk.

Vicarious heterosexism-based stress induces alcohol, nicotine, and cannabis craving and negative affect among sexual minority young adults: An experimental study

Purpose

Sexual minority young adults are at increased risk for hazardous drinking and alcohol use disorder compared to heterosexual adults. Heterosexism-based stressors contribute and often explain inequities in alcohol outcomes. However, the extant research primarily relies on correlational designs, and often neglects the importance of alcohol craving, despite its foundational role in addiction. Leveraging a novel experimental mood induction paradigm, this study examined the effects of exposure to vicarious heterosexism-based stress on alcohol craving and negative affect among sexual minority young adults who drink heavily. We also examined its effects on cannabis and nicotine craving among participants who used cannabis and nicotine, respectively. Lastly, we examined moderating factors that could influence the impact of exposure to heterosexism-based stress on alcohol craving.

Methods

Participants were 101 heavy drinking sexual minority young adults, ages 20-35 (M = 26.46 years old; SD = 3.49), recruited from the community (51.5% female sex assigned at birth; 76.3% cisgender; 51.5% plurisexual; and 42.6% racial and ethnic minorities). They completed three mood induction trials counterbalanced over three visits on different days: heterosexism stress, general stress, and neutral. Structured interviews assessed criteria for DSM-5 alcohol use disorder (AUD) and substance use, and self-report measures assessed lifetime traumatic stressors.

Results

Most participants met criteria for past-year AUD (74.7%). Exposure to heterosexism stress produced more negative affect and substance craving than the neutral mood induction, even while controlling for demographic variables and lifetime exposure to traumatic and heterosexism stressors. Exposure to heterosexism-based stress had large effects on alcohol craving among participants who had greater drinking to cope motives and heterosexism-specific rejection sensitivity, whereas the effects were small for those who had lower drinking to cope motives and heterosexism-specific rejection sensitivity. Demographic, lifetime stress, prior alcohol use, and AUD symptom severity variables were not significant moderators. Greater substance craving induced by heterosexism-based stress in the laboratory was associated with greater recent and current substance use.

Conclusions

This study findings show that vicarious exposure to heterosexism elicits negative mood and alcohol, cannabis, and nicotine craving among sexual minority young adults who engaged in heavy drinking. The effects for alcohol craving were largest among those who endorse high levels of drinking to cope motives and heterosexism-based rejection sensitivity. These findings have implications for oppression-based stress and motivational models of addiction.

Supporting treatment adherence for resilience and thriving (START): protocol for a mHealth randomized controlled trial

BACKGROUND

Although behavioral interventions show some promise for reducing stimulant use and achieving durable viral suppression in sexual minority men (SMM) with HIV, scalable mHealth applications are needed to optimize their reach and cost-effectiveness.

METHODS

Supporting Treatment Adherence for Resilience and Thriving (START) is a randomized controlled trial (RCT) testing the efficacy and cost-effectiveness of a mHealth application that integrates evidence-based positive affect regulation skills with self-monitoring of adherence and mood. The primary outcome is detectable HIV viral load (i.e., > 300 copies/mL) from self-collected dried blood spot (DBS) specimens at 6 months. Secondary outcomes include detectable DBS viral load at 12 months, self-reported stimulant use severity, anti-retroviral therapy (ART) adherence, and positive affect over 12 months. A national sample of up to 250 SMM with HIV who screen positive for stimulant use disorder and reporting suboptimal ART adherence is being recruited via social networking applications through April of 2024. After providing informed consent, participants complete a run-in period (i.e., waiting period) including two baseline assessments with self-report measures and a self-collected DBS sample. Those who complete the run-in period are randomized to either the START mHealth application or access to a website with referrals to HIV care and substance use disorder treatment resources. Participants provide DBS samples at baseline, 6, and 12 months to measure HIV viral load as well as complete self-report measures for secondary outcomes at quarterly follow-up assessments over 12 months.

DISCUSSION

To date, we have paid $117,500 to advertise START on social networking applications and reached 1,970 eligible participants ($59.77 per eligible participant). Although we identified this large national sample of potentially eligible SMM with HIV who screen positive for a stimulant use disorder and report suboptimal ART adherence, only one-in-four have enrolled in the RCT. The run-in period has proven to be crucial for maintaining scientific rigor and reproducibility of this RCT, such that only half of consented participants complete the required study enrollment activities and attended a randomization visit. Taken together, findings will guide adequate resource allocation to achieve randomization targets in future mHealth research SMM with HIV who use stimulants.

TRIAL REGISTRATION

This protocol was registered on clinicaltrials.gov (NCT05140876) on December 2, 2021.

The Mediating Role of Problematic Alcohol Consumption on the Association Between Pandemic-Related Strains and Domestic Violence Across Six Countries

Research has documented that domestic violence increased worldwide during the COVID-19 pandemic. Studies have also suggested that alcohol use, which also increased during COVID-19, is a risk factor for domestic violence victimization. However, research has yet to examine whether alcohol consumption mediated the relationship between pandemic-related stressful events and domestic violence. Using structural equation modeling, the current study examines the impact of three types of pandemic-related strains (financial problems, familial problems, and work problems) on individual assessments about whether their drinking became problematic during the pandemic and then whether problematic alcohol use increases the risk of psychological and physical domestic violence. This model was analyzed across six countries: Ukraine, The Netherlands, Pakistan, Denmark, Guatemala, and the United States. Results indicate that the associations between pandemic-related strains and self-assessed problematic drinking varied by country. However, across all countries, problematic alcohol consumption was associated with increased physical and psychological domestic violence victimization. Overall, the findings of the current study support the use of programs that aim to reduce problematic consumption of alcohol with the hopes that they may, in turn, reduce psychological and physical domestic violence victimization.

Does how individuals handle social situations exacerbate the relationship between physique anxiety and food addiction? The role of emotional expressive suppression and social avoidance and distress

Background

Research on food addiction has increased significantly in recent years. It has been demonstrated that food addiction can lead to impairments in physiological, psychological, and social functioning in individuals. However, there is a lack of studies investigating the influence of how individuals handle social situations on food addiction and the specific mechanisms involved.

Method

A cross-sectional survey was conducted with 1,151 university students, with a mean age of 21.44 (SD = 4.77) years. The sample comprised 74.46% female and 25.54% male students. Participants completed the Chinese version of the modified Yale Food Addiction Scale 2.0, the Social Physique Anxiety Scale, the Expressive Suppression Scale, and the Social Avoidance and Distress Scale. Statistical analyses were performed using SPSS 26.0 and the Process (Version 3.4) plug-in.

Result

The results of the study supported our hypothesis that the association between social physique anxiety and food addiction symptoms could be partially explained by expressive suppression and social avoidance and distress. This association remained significant even after adjusting for covariates such as gender, number of cigarettes smoked per day, bedtime, education, and BMI. Specifically, more severe social physique anxiety was found to be associated with frequent use of expressive suppression and social avoidance and distress, which in turn was associated with more severe food addiction symptoms.

Conclusion

This study explored the role of expression suppression and social avoidance and distress in the relationship between social physique anxiety and food addiction symptoms. The findings provide a theoretical basis for developing interventions for food addiction in college students. These interventions could include helping students develop a healthy perception of body image, encouraging emotional expression, and promoting active social participation to reduce food addiction symptoms.

Cigarette Smoking in Women Victims of Police-Reported Intimate Partner Violence: The Role of Childhood Maltreatment, Type of Partner Abuse, and Psychological Distress Symptoms

Existing research on the relationship between intimate partner violence (IPV) and cigarette smoking primarily involves low-risk, physical IVP-focused studies on community women. As a result, the risks associated with cigarette smoking in women victims of severe IPV have not been fully explored. This study examined the association between exposure to different forms of childhood maltreatment, exposure to physical, psychological, and sexual IPV, and current psychological distress symptoms with cigarette smoking in a high-risk sample of women victims of police-reported severe IPV. Participants included 162 women victims of police-reported severe IPV recruited in shelters for domestic violence and Child Protective Services in Portugal. Participants provided self-reports on childhood maltreatment physical, psychological, and sexual violence), physical, psychological, and sexual IPV, psychological distress symptoms (anxiety, depressive, somatic, and posttraumatic stress disorder symptoms), and daily cigarette consumption. Results revealed significant associations between daily cigarette consumption and exposure to IPV, physical abuse during childhood, psychological IPV, and anxiety symptoms in women experiencing police-reported severe IPV. Childhood maltreatment may increase vulnerability for emotion dysregulation, promoting addictive behaviors to regulate distress. Smoking can be an unhealthy regulating strategy to reduce the distress related to chronic exposure to psychological IPV. Future effective health promotion interventions in women facing severe forms of IPV may target emotional regulation and incorporate a trauma-focused approach.

The Indirect Influence of Cannabis Use Disorder Symptoms on PTSD Symptom Severity Through Psychological Inflexibility

Background: One in five college students (21%) report using cannabis in the past month, and approximately 10% develop cannabis use disorder (CUD). Further, college students have high rates of trauma exposure, and CUD is prospectively linked to posttraumatic stress disorder (PTSD). Given the high rate of co-occurrence, research is needed to understand transdiagnostic, modifiable factors that could account for the relationship between CUD and PTSD. Psychological inflexibility (PI) is one such factor and refers to difficulty adapting thoughts or behaviors to various situations that reflect of one's personal values. Objectives: PI predicts worse PTSD symptom severity and has been established as a maintaining factor between alcohol use and PTSD, albeit no studies have examined this relationship with CUD. Results: College students (N = 336) completed self-report measures of CUD, PI, and PTSD. A cross-sectional mediation model explained 54% of the variance in PTSD symptom severity, F(5, 330) = 78.86, p < .001. After controlling for age, gender, and probable alcohol use disorder, CUD was not directly associated with PTSD symptom severity, yet was indirectly associated with PTSD through higher PI. Specifically, CUD was associated with higher PI (b = 0.31, p < .05, 95% CI [0.07, 0.54]), and higher PI was associated with greater PTSD symptom severity (b = 1.07, p < .001, 95% CI [0.95, 1.19]). Conclusion: Although CUD has been previously linked with worse PTSD symptoms, results suggest that this occurs through PI. Importantly, PI is malleable, and may be an important treatment target for co-occurring CUD and PTSD in college students.

Aversion-induced drug taking and escape behavior involve similar nucleus accumbens core dopamine signaling signatures

Dopamine release in the nucleus accumbens core (NAcC) has long been associated with the promotion of motivated behavior. However, inhibited dopamine signaling can increase behavior in certain settings, such as during drug self-administration. While aversive environmental stimuli can reduce dopamine, it is unclear whether such stimuli reliably engage this mechanism in different contexts. Here we compared the physiological and behavioral responses to the same aversive stimulus in different designs to determine if there is uniformity in the manner that aversive stimuli are encoded and promote behavior. NAcC dopamine was measured using fiber photometry in male and female rats during cocaine self-administration sessions in which an acutely aversive 90 dB white noise was intermittently presented. In a separate group of rats, aversion-induced changes in dopamine were measured in an escape design in which operant responses terminated aversive white noise. Aversive white noise significantly reduced NAcC dopamine and increased cocaine self-administration in both male and female rats. The same relationship was observed in the escape design, in which white noise reduced dopamine and promoted escape attempts. In both designs, the magnitude of the dopamine reduction predicted behavioral performance. While prior research demonstrated that pharmacologically reduced dopamine signaling can promote intake, this report demonstrates that this physiological mechanism is naturally engaged by aversive environmental stimuli and generalizable to non-drug contexts. These findings illustrate a common physiological signature in response to aversion that may promote both adaptive and maladaptive behavior.

Substance use trajectories among urban college students: associations with symptoms of stress, anxiety, and depression before and during COVID-19

This study explored substance use trajectories and associations with mental health among an ethnically/racially diverse college student sample before and during the COVID-19 pandemic. We combined repeated cross-sections and panel data from a total of 3,247 college students assessed with an online survey in 2018, 2019, and in three waves in 2020. We estimated trends in substance use and their relation to mental health over the survey waves using generalized estimating equations (GEE). Our results revealed notable associations between 30-day substance use patterns, time of assessment, and psychological well-being. These findings suggest a complex interplay between access to substances, context of substance use, and mental health. We discuss several initiatives that have been launched in response to the results of this ongoing study. Such initiatives may serve as examples for expanding similar efforts to other commuter colleges to prevent further increases in mental health problems and risky substance use.

Hair cortisol and substance use among women currently experiencing intimate partner violence: The role of PTSD symptom severity

INTRODUCTION

Substance use is highly prevalent among women experiencing intimate partner violence (IPV) and has been associated with dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis and resulting cortisol response. Posttraumatic stress disorder (PTSD) symptoms may play an important role in exacerbating the association between cortisol levels and substance use behaviors.

PURPOSE

This study examined the role of PTSD symptoms in the relation between cortisol and past month substance use behaviors. The current study used hair cortisol as an index of past 30-day HPA-axis functioning and ecological momentary assessment (EMA) to characterize substance use behaviors more accurately over a 30-day period.

METHOD

Participants were 90 community women who had experienced physical or sexual IPV in the past 30 days by their current male partner and used any amount of alcohol or drugs (M age = 40.71; 54.4 % white). Participants completed (a) a baseline interview, (b) EMA for 30-days, and (c) a follow up interview where they were asked to provide a hair sample for cortisol analyses. Data collection took place from 2018 to 2020.

RESULTS

PTSD severity moderated the relations between cortisol and days of drinking and binge drinking. In the context of high PTSD symptomology, women with high cortisol levels spent, on average, an additional 7.4 days drinking and 8.1 days binge drinking in the past 30 days compared to women with low cortisol levels, in a model adjusted for age.

CONCLUSIONS

Results highlight the prominent role of PTSD symptoms in the association between cortisol and alcohol use among women experiencing IPV.
