    Abstract Evidence-based treatments for posttraumatic stress disorder (PTSD) are underutilized by active duty service members in the United States. Social support may help service members overcome avoidance and facilitate treatment utilization. In turn, treatment utilization may improve social support. To evaluate these possibilities, the aim of the current study was to examine potential reciprocal associations between social support and treatment utilization among service members. Secondary analyses were conducted on a randomized controlled trial of 161 U.S. military service members with PTSD. Participants completed assessments of perceived social support and attendance at individual therapy sessions at baseline and 3- and 6-month follow-ups. To determine reciprocal relations between social support and treatment utilization, a Bayesian approach was used to estimate a random-intercept cross-lagged panel model with a two-part variable for treatment utilization (i.e., any therapy, and if so, dose). There were no between-person associations between average social support and treatment utilization. One prospective cross-lagged within-person association emerged as significant: social support at 3 months was negatively associated with any therapy use at 6 months; the model explained 26.1% of the variance in this observed variable. The findings revealed that low social support promoted subsequent treatment utilization, but such treatment did not lead to changes in social support. This suggests service members with PTSD may have been motivated to attend individual therapy in pursuit of social connection and support. Future research is needed to determine if reciprocal associations between various forms of social support and therapy utilization differ by treatment modality.

    Abstract Eight states and the District of Columbia have legalized the recreational use of cannabis for adults and more are expected to follow suit. After alcohol, cannabis is the most commonly used drug by adolescents. Consumption of this drug during this developmental period poses unique risks. Therefore, attention must be paid both to how legalization affects adolescents and how tailored interventions can effectively address their needs for assistance. This commentary offers considerations for how legalization might be crafted so as to benefit adolescents. It additionally focuses on how services might be designed to reach and intervene with teens who are questioning their use or are experiencing a cannabis use disorder and desire assistance in quitting.

    Abstract Young adults with first episode psychosis use cannabis at high rates. In light of progressively tolerant attitudes toward cannabis, decreased perceptions of risk, and limited implementation of substance use modules within coordinated specialty care (CSC) programs, this study sought to describe factors contributing to CSC providers' intentions to implement motivational enhancement therapy (MET) for cannabis reduction. Two focus groups were conducted with CSC providers (n = 14), with questions guided by theory of planned behavior. Content and thematic analyses were conducted to identify salient themes associated with the theory. Participants generally indicated intentions to implement MET; limiting factors included concerns about clients' willingness to discuss cannabis use, perception of support for abstinence-only goals, and concerns about intervention mechanics such as computerized assessments. To reduce barriers limiting provider intention to implement MET, authors recommend training on assessment protocols, the merits of harm-reduction, and strategies for lower-risk cannabis use.Please confirm if the author names are presented accurately and in the correct sequence.

    Abstract Objective: Posttraumatic stress disorder (PTSD) prevalence in the military is high and effective treatments are underutilized. Motivational enhancement therapy (MET) "check-ups" are brief interventions to elicit treatment uptake for those who are nontreatment seeking. The aim of the current study was to test the efficacy of a novel MET intervention designed to promote treatment engagement among active-duty U.S. military personnel with untreated PTSD.
    Method: One hundred and sixty-one active-duty service members who met the criteria for PTSD were randomized to MET or treatment as usual (TAU, treatment resource and referral). MET participants (
    Results: Mixed effect model results indicated treatment uptake significantly increased over time but there were no significant differences between conditions or interactions. PTSD symptom severity significantly decreased for both conditions. There was also a significant three-way interaction with baseline readiness-to-change confidence. Those low in baseline readiness-to-change saw more favorable effects of MET (relative to TAU) at 6-month follow-up.
    Conclusions: Results suggest both MET and high-quality referral options have promise as a means of increasing evidence-based treatment uptake and decreasing PTSD for service members with PTSD. MET may be particularly useful for individuals with low confidence in their ability to address PTSD. Given the individual and societal costs of PTSD, there is a need for interventions facilitating treatment uptake. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

    Abstract Introduction: The current study investigated providers' perceived barriers, supports, and need for adopting a screening, brief intervention, and referral to treatment model (SBIRT) intervention related to cannabis reduction into their community based primary care clinics.
    Methods: Eleven pediatric primary care providers from regional community-based clinics participated in focus groups discussing a proposed adolescent cannabis use SBIRT reduction intervention, perceived need, and potential barriers to implementation within their clinic.
    Results: Seven primary themes emerged regarding barriers to implementing a cannabis reduction SBIRT in primary care including provider ambivalence to adolescent cannabis use.
    Conclusion: Further research is needed to understand evolving provider perceptions of adolescent cannabis use and how these views impact the adoption of SBIRT for the reduction of cannabis use among their adolescent patients.

    Abstract Objective: Posttraumatic stress disorder (PTSD) with comorbid substance use disorders (SUDs) has been associated with poorer treatment outcomes. The present study examined associations between provisional PTSD at baseline and 3 months with 6-month treatment outcomes from either a one-session motivational enhancement therapy (MET) or education intervention addressing substance use.
    Method: Secondary analyses were conducted on a randomized clinical trial comparing a novel MET intervention to an educational intervention for Army personnel with SUD who were not engaged in SUD treatment (
    Results: Individuals with unremitted provisional PTSD were at increased risk for moderate/severe alcohol use disorder at 6 months relative to those without baseline provisional PTSD (odds ratio = 4.53,
    Conclusions: Both interventions were effective in reducing drinking even for those with provisional PTSD, although, compared with education, MET had slightly better effects on reducing drinking quantity for those with remitted PTSD. Findings suggest that PTSD remission may serve as an early prognostic indicator of long-term alcohol use changes, or alternatively, delivery of MET during heightened transitory distress may be most effective for reducing alcohol use.

    Abstract Objective: Young adults experiencing a first episode of psychosis (FEP) have high rates of cannabis use and cannabis use disorder (CUD). No evidence-based practice effectively treats CUD for people with FEP, and little is known about factors that influence intentions to reduce or stop using. A critical inquiry was conducted to identify salient factors contributing to intentions of young adults with FEP to reduce or discontinue cannabis use, guided by theory of planned behavior (TPB).
    Method: Online focus groups (
    Results: Participants identified benefits of cannabis reduction and cessation for pursuing life goals, but most maintained regular use. Participants perceived cannabis as a facilitator of social interactions, enjoyable activities, and improved mental health (and reduced dysthymia). Many were concerned about reducing or discontinuing cannabis without replacement strategies to compensate for its benefits.
    Conclusions and implications for practice: In spite of life goals incompatible with cannabis use, cessation was not favored given the perceived benefits of cannabis and participants' lack of replacement strategies to facilitate social interactions, enjoyable activities, and euthymia. Interventions may be improved by addressing motivations for use and by teaching skills to build positive social support, schedule enjoyable activities, and ameliorate dysthymia.
