The Indirect Relationship Between Interpersonal Trauma History and Alcohol Use via Negative Cognitions in a Multisite Alcohol Treatment Sample

Predictors of Treatment Completion among Women Receiving Integrated Treatment for Comorbid Posttraumatic Stress and Substance Use Disorders

Background: Retention in treatment for individuals with comorbid posttraumatic stress disorder (PTSD) and substance use disorders (SUD) is an area of concern in treatment outcome studies. The current study explores key variables related to retention in a group of women with comorbid PTSD and SUD enrolled in community SUD treatment randomized to eight weekly sessions of a trauma adapted mindfulness-based relapse prevention (TA-MBRP) or an integrated coping skills (ICS) group intervention. Methods: Two unadjusted and adjusted logistic discrete failure time (DFT) models were fit to examine associations between participants and the time (in weeks) to treatment completion status. Key covariates of interest, including time-varying PTSD Symptom Scale-Self Report (PSS) total score, time-varying Five Factors Mindfulness Questionnaire (FFMQ) total score, group assignment, baseline endorsements of substance use and demographics such as age, race and employment status were fit into the model. Results: In the adjusted PSS model, increased levels of PTSD symptom severity (PSS) scores at week 5 and 7 (PSS OR: 1:06: OR 1.13, respectively) were associated with higher odds of non-completion. In the FFMQ model, increased levels of FFMQ scores at week 6 (OR: 0:92) were associated with lower odds of non-completion. In both models, assignment to the ICS control group and unemployment were associated with lower odds of completion and baseline use of cocaine and sedatives were associated with higher odds of completion. Conclusion: Monitoring PTSD symptom severity and measures of mindfulness can inform providers on strategies to enhance retention early in treatment for individuals with comorbid PTSD/SUD.ClinicalTrials.gov # NCT02755103.

Posttraumatic cognitions and sexual assault: Understanding the role of cognition type in posttraumatic stress symptoms and problematic alcohol use

Identifying potential mechanisms underlying the association between posttraumatic stress symptoms (PTSS) and problematic alcohol use is an important target among college women who have experienced sexual assault. This study examined the role of posttraumatic cognitions in this association among college women (N = 530) who experienced either an alcohol-involved assault or non-alcohol-involved assault, using baseline assessment data from a larger study examining cognitive and emotional risk factors for problem drinking. Conditional path analysis was used to examine the indirect effects of posttraumatic cognitions on the association between PTSS and alcohol use consequences, with assault type as a moderator. The findings revealed a significant indirect path from PTSS to alcohol use consequences through posttraumatic cognitions, B = 0.21, SE = 0.04, p < .001, 95% CI [0.13, 0.29], β = .16, R² = .32. Exploratory analyses revealed a significant conditional indirect effect through self-blame cognitions, R² = .31, whereby the indirect effect of self-blame on the association between posttraumatic stress and alcohol consequences was present among participants who experienced alcohol-involved assault, B = 0.10, SE = 0.03, p < .001, 95% CI [0.06, 0.16], β = .07, but not among those who experienced a non-alcohol-involved assault, B = 0.03, SE = 0.03, p = 0.32, 95% CI [-0.02, 0.08], β = .02. Posttraumatic cognitions are a potential mechanism underlying the link between posttraumatic stress and alcohol consequences. Addressing posttraumatic cognitions, particularly those related to self-blame, may be an important target for interventions promoting healthy recovery following alcohol-involved assault.

Longitudinal associations between childhood sexual abuse-related PTSD symptoms and passive and active suicidal ideation among sexual minority men

BACKGROUND

Sexual minority men report high rates of childhood sexual abuse (CSA) and adulthood suicidality. However, mechanisms (e.g., PTSD symptoms) through which CSA might drive suicidality remain unknown.

OBJECTIVE

In a prospective cohort of sexual minority men, we examined: (1) associations between CSA and suicidal thoughts and behaviors; (2) prospective associations between CSA-related PTSD symptoms and suicidal ideation; and (3) interpersonal moderators of these associations.

PARTICIPANTS AND SETTING

Participants included 6305 sexual minority men (M_age = 33.2, SD = 11.5; 82.0% gay; 53.5% White) who completed baseline and one-year follow-up at-home online surveys.

METHODS

Bivariate analyses were used to assess baseline demographic and suicidality differences between CSA-exposed participants and non-CSA-exposed participants. Among CSA-exposed participants, multivariable logistic regression analyses were used to regress passive and active suicidal ideation at one-year follow-up on CSA-related PTSD symptoms at baseline. Interactions were examined between CSA-related PTSD symptoms and interpersonal difficulties.

RESULTS

CSA-exposed sexual minority men reported two-and-a-half times the odds of suicide attempt history compared to non-CSA-exposed men (95% CI = 2.15-2.88; p < 0.001). Among CSA-exposed sexual minority men, CSA-related PTSD symptoms were prospectively associated with passive suicidal ideation (adjusted odds ratio [aOR] = 1.38; 95% CI = 1.19; 1.61). Regardless of CSA-related PTSD symptom severity, those with lower social support and greater loneliness were at elevated risk of active suicidal ideation at one-year follow-up.

CONCLUSIONS

CSA-related PTSD symptom severity represents a psychological mechanism contributing to CSA-exposed sexual minority men's elevated suicide risk, particularly among those who lack social support and report loneliness.
