Mindfulness-based cognitive therapy (MBCT) appears to be a promising intervention for the prevention of relapse in major depressive disorder, but its efficacy in patients with current depressive symptoms is less clear. Randomized clinical trials of MBCT for adult patients with current depressive symptoms were included (k = 13, N = 1046). Comparison conditions were coded based on whether they were intended to be therapeutic (specific active controls) or not (non-specific controls). MBCT was superior to non-specific controls at post-treatment (k = 10, d = 0.71, 95% confidence interval [CI] [0.47, 0.96]), although not at longest follow-up (k = 2, d = 1.47, [-0.71, 3.65], mean follow-up = 5.70 months across all studies with follow-up). MBCT did not differ from other active therapies at post-treatment (k = 6, d = 0.002, [-0.43, 0.44]) and longest follow-up (k = 4, d = 0.26, [-0.24, 0.75]). There was some evidence that studies with higher methodological quality showed smaller effects at post-treatment, but no evidence that effects varied by inclusion criterion. The impact of publication bias appeared minimal. MBCT seems to be efficacious for samples with current depressive symptoms at post-treatment, although a limited number of studies tested the long-term effects of this therapy.

Posttraumatic stress disorder (PTSD) and alcohol dependence (AD) frequently co-occur, although results of both cross-sectional and longitudinal studies evaluating the nature of their relationship have been mixed. There has been varied support for competing models explaining how these conditions influence one another. To assess both the self-medication and mutual maintenance models, as well as examine the potential moderating role of drinking motives, the current study used Generalized Estimating Equations to evaluate daily associations for an average of 7.3 days between PTSD symptoms and alcohol use in a mixed-gender sample of individuals who met criteria for both PTSD and AD. Results generally supported a self-medication model with elevated PTSD symptoms predictive of greater alcohol use on that same day and on the following day. Contrary to a mutual maintenance model prediction, drinking did not predict next-day PTSD symptoms. Results also indicated that both coping and enhancement drinking motives were significant moderators of the PTSD and drinking relationships, suggesting that these relationships may be more or less salient depending on an individual's particular drinking motivations. For example, among those higher on coping drinking motives, a 1-unit increase in PTSD symptom severity was associated with a 35% increase in amount of alcohol consumed the same day, while among those low on coping drinking motives, a 1-unit PTSD increase was associated with only a 10% increase in alcohol consumption. We discuss implications of these findings for the larger literature on the associations between PTSD and alcohol use as well as for clinical interventions.

Background:  Current medications for alcohol dependence (AD) show only modest efficacy. None target brain noradrenergic pathways. Theory and preclinical evidence suggest that noradrenergic circuits may be involved in alcohol reinforcement and relapse. We therefore tested the α‐1 adrenergic receptor antagonist, prazosin, as a pharmacotherapy for AD.Methods:  We randomized 24 participants with AD but without posttraumatic stress disorder to receive either prazosin or placebo in a 6‐week, double‐blind pilot study. Medication was titrated to a target dose of 4 mg QAM, 4 mg QPM, and 8 mg QHS by the end of week 2. Participants received 5 medical management treatment sessions. Participants were reminded 3 times each day via a text pager to take medications and to call a telephone monitoring system once daily to provide self‐reports of alcohol consumption and craving, the primary outcome measures. Results were analyzed using mixed linear regression adjusted for drinking days per week at baseline and week number.Results:  Twenty of the 24 (83%) subjects completed. Among the completers, the prazosin group reported fewer drinking days per week than the placebo group during the final 3 weeks of the study. Since only 1 woman was randomized to placebo and only three women completed the trial, the following results focus on the 17 male completers. The prazosin group reported fewer drinking days per week and fewer drinks per week during the final 3 weeks of the study; average total number of drinking days for the placebo group 5.7 (SEM 1.9) versus 0.9 (SEM 0.5) for the prazosin group, and average total number of drinks 20.8 (SEM 6.5) for the placebo group versus 2.6 (SEM 1.3) for the prazosin group. Rates of adverse events were equivalent across conditions.Conclusions:  Prazosin holds promise as a pharmacologic treatment for AD and deserves further evaluation in a larger controlled trial.

Over the past 20 years, numerous treatments addressing comorbid Posttraumatic Stress Disorder (PTSD) and Substance Use Disorder (SUD) have been developed and tested. The current meta-analysis examined the efficacy and acceptability of the two central treatment types– trauma-focused and non-trauma-focused – compared with all comparators and with cognitive-behavioral manualized SUD treatments immediately post-treatment and at longest follow-up. Twenty-eight randomized clinical trials (N = 3247) were included. There were small to large within-group effects for all forms of active treatment (gs = 0.30–1.11). Trauma-focused but not non-trauma-focused treatments outperformed all comparators on PTSD outcomes at post-treatment. Neither trauma-focused nor non-trauma-focused treatment outperformed all comparators on SUD outcomes at post-treatment. Neither trauma- nor non-trauma-focused treatment outperformed manualized SUD treatments on PTSD outcomes at either time point. Manualized SUD treatments outperformed trauma-focused treatments on SUD outcomes at post-treatment and non-trauma-focused treatments on PTSD outcomes at follow-up. Regarding treatment retention, neither trauma-focused nor non-trauma-focused treatments significantly differed from all comparators or from manualized SUD treatments. Between-group results were largely unchanged in trim-and-fill analyses, but were not robust to fail-safe N. Few moderators were detected. Taken together, results suggest that trauma-focused, non-trauma-focused, and manualized SUD interventions are sound options for individuals with comorbid PTSD/SUD.
