Disparate prevalence estimates of PTSD among service members who served in Iraq and Afghanistan: Possible explanations

The authors reviewed 29 studies that provide prevalence estimates of posttraumatic stress disorder (PTSD) among service members previously deployed to Operations Enduring and Iraqi Freedom and their non-U.S. military counterparts. Studies vary widely, particularly in their representativeness and the way PTSD is defined. Among previously deployed personnel not seeking treatment, most prevalence estimates range from 5 to 20%. Prevalence estimates are generally higher among those seeking treatment: As many as 50% of veterans seeking treatment screen positive for PTSD, though much fewer receive a PTSD diagnosis. Combat exposure is the only correlate consistently associated with PTSD. When evaluating PTSD prevalence estimates among this population, researchers and policymakers should carefully consider the method used to define PTSD and the population the study sample represents.

Transactional sex among men and women in the south at high risk for HIV and other STIs.

Transactional sex refers to selling sex (exchanging sex for money, drugs, food, shelter, or other items) or purchasing sex (exchanging money, drugs, food, shelter, or other items for sex). These activities have been associated with a higher risk for HIV and other sexually transmitted infections in a variety of populations and settings. This paper examines correlates of purchasing and selling sex in a large sample of drug users, men who have sex with men, and sex partners of these groups. Using respondent-driven sampling, participants were recruited between 2005 and 2008 in two urban and two rural counties in North Carolina. We used multiple logistic regressions to examine separate models for selling and purchasing sex in men and women. In addition, we estimated direct and indirect associations among independent variables in the logistic regression models and transactional sex using structural equation models. The analysis shows that factors associated with women selling and buying sex include being homeless, use of stimulants, bisexual behavior, and neighborhood disorder. There was also a significant difference by race. For men, the factors associated with selling and buying sex include being homeless, bisexual behavior, and not being in a relationship. Although neighborhood violence and disorder show significance in bivariate associations with the outcome, these associations disappear in the structural equation models.

Group motivational interviewing for adolescents: change talk and alcohol and marijuana outcomes.

OBJECTIVE Little is known about what may distinguish effective and ineffective group interventions. Group motivational interviewing (MI) is a promising intervention for adolescent alcohol and other drug use; however, the mechanisms of change for group MI are unknown. One potential mechanism is change talk, which is client speech arguing for change. The present study describes the group process in adolescent group MI and effects of group-level change talk on individual alcohol and marijuana outcomes. METHOD We analyzed 129 group session audio recordings from a randomized clinical trial of adolescent group MI. Sequential coding was performed with the Motivational Interviewing Skill Code (MISC) and the CASAA Application for Coding Treatment Interactions software application. Outcomes included past-month intentions, frequency, and consequences of alcohol and marijuana use; motivation to change; and positive expectancies. RESULTS Sequential analysis indicated that facilitator open-ended questions and reflections of change talk increased group change talk. Group change talk was then followed by more change talk. Multilevel models accounting for rolling group enrollment revealed group change talk was associated with decreased alcohol intentions, alcohol use, and heavy drinking 3 months later; group sustain talk was associated with decreased motivation to change, increased intentions to use marijuana, and increased positive alcohol and marijuana expectancies. CONCLUSIONS Facilitator speech and peer responses each had effects on change and sustain talk in the group setting, which were then associated with individual changes. Selective reflection of change talk in adolescent group MI is suggested as a strategy to manage group dynamics and increase behavioral change.

A randomized controlled trial of a group motivational interviewing intervention for adolescents with a first time alcohol or drug offense

Group motivational interviewing (MI) interventions that target youth at-risk for alcohol and other drug (AOD) use may prevent future negative consequences. Youth in a teen court setting [n=193; 67% male, 45% Hispanic; mean age 16.6 (SD=1.05)] were randomized to receive either a group MI intervention, Free Talk, or usual care (UC). We examined client acceptance, and intervention feasibility and conducted a preliminary outcome evaluation. Free Talk teens reported higher quality and satisfaction ratings, and MI integrity scores were higher for Free Talk groups. AOD use and delinquency decreased for both groups at 3 months, and 12-month recidivism rates were lower but not significantly different for the Free Talk group compared to UC. Results contribute to emerging literature on MI in a group setting. A longer term follow-up is warranted.

Developing a Group Motivational Interviewing Intervention for First-Time Adolescent Offenders At-Risk for an Alcohol or Drug Use Disorder

This study examined how teens who had committed a first-time alcohol or other drug (AOD) offense responded to a motivational interviewing (MI) group intervention. Participants were 101 first-time AOD adolescent offenders (M = 15.88; 63% male, 54% Hispanic). The authors developed and tested a six-session curriculum called Free Talk and solicited feedback from different teens after each session. Groups were recorded and transcribed. Feedback was categorized using the Motivational Interviewing Treatment Integrity scale (MITI 3.0). Feedback indicated high levels of evocation, collaboration, autonomy/support, and empathy. The current study highlights that utilizing group MI can be an acceptable approach for at-risk youth.

Exploring productivity outcomes from a brief intervention for at-risk drinking in an employee assistance program.

Brief intervention (BI) research has traditionally examined alcohol and drug use outcomes; however it is unknown whether BIs can also impact on-the-job productivity. This exploratory study examines changes in workplace productivity and related costs for clients receiving a BI for at-risk drinking in the employee assistance program (EAP). Participants were 44 clients attending the EAP for behavioral health concerns, screened for at-risk drinking, assigned to BI+Usual Care (n=25) or UC alone (n=19), and who completed 3-month follow-up. Absenteeism, presenteeism, and productivity costs were derived as outcomes. At follow-up, participants in the BI+UC group had improved productivity when at work (presenteeism) compared to the UC group. The estimated cost savings from improved productivity for the BI+UC group was

Developing an integrated treatment for substance use and depression using cognitive–behavioral therapy

1200 per client over the UC group. Groups did not differ by absenteeism (missed days of work). Preliminary evidence suggests the broad impact BIs may have. Implications for future BI research are discussed.

Collaborative Care for Opioid and Alcohol Use Disorders in Primary Care: The SUMMIT Randomized Clinical Trial

Providing a unified treatment approach to meet the substance abuse and mental health needs of clients is the preferred model for addressing co-occurring disorders. We developed a group-based cognitive-behavioral (CBT) integrated treatment for depression and substance use disorders (SUD) that could be delivered by counselors in SUD treatment settings and evaluated its feasibility and acceptability. We conducted an in-depth case study examining one implementation of the treatment using 15 focus groups with clients (n = 7) and semistructured interviews with counselors (n = 2) and administrators (n = 3). Using CBT as a treatment approach to integrate the treatment was widely accepted by clients, counselors, and administrators. Clients stated the treatment was applicable to multiple aspects of their lives and allowed them to recognize their clinical improvements over time. Counselors and administrators discussed challenges for long-term feasibility. Key decisions used to develop the treatment and recommendations for implementing integrated care in SUD settings are discussed.

Assessing Motivational Interviewing Integrity for Group Interventions with Adolescents

Importance Primary care offers an important and underutilized setting to deliver treatment for opioid and/or alcohol use disorders (OAUD). Collaborative care (CC) is effective but has not been tested for OAUD. Objective To determine whether CC for OAUD improves delivery of evidence-based treatments for OAUD and increases self-reported abstinence compared with usual primary care. Design, Setting, and Participants A randomized clinical trial of 377 primary care patients with OAUD was conducted in 2 clinics in a federally qualified health center. Participants were recruited from June 3, 2014, to January 15, 2016, and followed for 6 months. Interventions Of the 377 participants, 187 were randomized to CC and 190 were randomized to usual care; 77 (20.4%) of the participants were female, of whom 39 (20.9%) were randomized to CC and 38 (20.0%) were randomized to UC. The mean (SD) age of all respondents at baseline was 42 (12.0) years, 41(11.7) years for the CC group, and 43 (12.2) yearsfor the UC group. Collaborative care was a system-level intervention, designed to increase the delivery of either a 6-session brief psychotherapy treatment and/or medication-assisted treatment with either sublingual buprenorphine/naloxone for opioid use disorders or long-acting injectable naltrexone for alcohol use disorders. Usual care participants were told that the clinic provided OAUD treatment and given a number for appointment scheduling and list of community referrals. Main Outcomes and Measures The primary outcomes were use of any evidence-based treatment for OAUD and self-reported abstinence from opioids or alcohol at 6 months. The secondary outcomes included the Healthcare Effectiveness Data and Information Set (HEDIS) initiation and engagement measures, abstinence from other substances, heavy drinking, health-related quality of life, and consequences from OAUD. Results At 6 months, the proportion of participants who received any OAUD treatment was higher in the CC group compared with usual care (73 [39.0%] vs 32 [16.8%]; logistic model adjusted OR, 3.97; 95% CI, 2.32-6.79; P < .001). A higher proportion of CC participants reported abstinence from opioids or alcohol at 6 months (32.8% vs 22.3%); after linear probability model adjustment for covariates (&bgr; = 0.12; 95% CI, 0.01-0.23; P = .03). In secondary analyses, the proportion meeting the HEDIS initiation and engagement measures was also higher among CC participants (initiation, 31.6% vs 13.7%; adjusted OR, 3.54; 95% CI, 2.02-6.20; P < .001; engagement, 15.5% vs 4.2%; adjusted OR, 5.89; 95% CI, 2.43-14.32; P < .001) as was abstinence from opioids, cocaine, methamphetamines, marijuana, and any alcohol (26.3% vs 15.6%; effect estimate, &bgr; = 0.13; 95% CI, 0.03-0.23; P = .01). Conclusions and Relevance Among adults with OAUD in primary care, the SUMMIT collaborative care intervention resulted in significantly more access to treatment and abstinence from alcohol and drugs at 6 months, than usual care.

Longitudinal Family Effects on Substance Use Among an At-Risk Adolescent Sample

The group format is commonly used in alcohol and other drug (AOD) adolescent treatment settings, but little research exists on the use of motivational interviewing (MI) in groups. Further, little work has assessed the integrity of MI delivered in group settings. This study describes an approach to evaluate MI integrity using data from a group MI intervention for at-risk youth. Using the Motivational Interviewing Treatment Integrity (MITI) scale, version 3.1, we coded 140 group sessions led by 3 different facilitators. Four trained coders assessed the group sessions. Agreement between raters was evaluated using a method based on limits of agreement, and key decisions used to monitor and calculate group MI integrity are discussed. Results indicated that there was adequate agreement between raters; we also found differences on use of MI between the MI-intervention group and a usual-care group on MI global ratings and behavioral counts. This study demonstrates that it is possible to determine whether group MI is implemented with integrity in the group setting and that MI in this setting is different from what takes place in usual care.
