ObjectiveColleges continue to experience a high number of referred students because of campus alcohol violations. Subsequently, there has been a trend to use peer-implemented minimal interventions (PMIs), often using motivational interviewing (MI). However, little is known about how PMIs facilitate behavior change. This study aims to examine the mechanisms of behavior change within PMIs and their influence on alcohol reduction among mandated students.MethodParticipants (N = 146; mean age = 18.7 years; 67% male; 94% White) were college students who violated campus alcohol policy at a Northeastern liberal arts college who received a 15-minute PMI addressing their alcohol use. The Motivational Interviewing Skill Code (Miller et al., 2003) was used to identify peer counselor behaviors that were MI consistent (MICO), client change talk (CT), and client self-exploration.ResultsMICO behaviors were positively associated with CT and self-exploration. Client CT and self-exploration were negatively associated with alcohol-related outcomes. Furthermore, mediational models examining MICO behaviors revealed effects for two paths: (a) from MICO to client CT to reduced alcohol use; and (b) from MICO to client self-exploration to reduced alcohol-related consequences and use.ConclusionsThese data support the primary causal chain examining the influence of MICO on in-session client behaviors and related post-session behavior change in PMIs among at-risk students.

Soy isoflavones have functional similarity to human estrogens and may protect against breast cancer as a result of their antiestrogenic activity or increase risk as a result of their estrogen-like properties. We examined the relation between isoflavone supplementation and mammographic density, a strong marker for breast cancer risk, among postmenopausal women. The Osteoporosis Prevention Using Soy (OPUS) study, a multi-site, randomized, double-blinded, and placebocontrolled trial assigned 406 postmenopausal women to 80 or 120 mg/d of isoflavones each or a placebo for 2 y. Percent densities were assessed in digitized mammograms using a computer-assisted method. The mammogram reader did not know the treatment status and the time of mammograms. We applied mixed models to compare breast density by treatment while considering the repeated measures. The mammographic density analysis included 358 women, 88.2 % of the OPUS participants; 303 had a complete set of 3 mammograms, 49 had 2, and 6 had only 1 mammogram. At baseline, the groups were similar in age, BMI, and percent density, but mean breast density differed by study site (P = 0.02). A model with all mammograms did not show a treatment effect on any mammographic measure, but the change over time was significant; breast density decreased by 1.6%/y across groups (P< 0.001). Stratification by age and BMI did not reveal any effects in subgroups. In this randomized 2-y trial, isoflavone supplements did not modify breast density in postmenopausal women. These findings offer reassurance that isofiavones do not act like hormone replacement medication on breast density.

Comorbidity is common with posttraumatic stress disorder, and alcohol use disorder (AUD) is among the most common co-occurring disorders. When viewed through the lens of avoidance behaviors, AUD can shape an individual's response to distressing trauma reminders by dulling the emotional response and promoting disengagement from the traumatic memory. Over time, this response strengthens posttraumatic distress by reinforcing the belief that traumatic memories and their emotional responses are themselves dangerous and intolerable. In turn, this belief may impede treatment progress. Concurrent trauma-focused therapy and AUD treatment can serve to establish more adaptive coping strategies. Reducing reliance on alcohol for coping while engaging safely and effectively with trauma memories allows the individual to process the memories, build tolerance to emotional distress, and ultimately reframe maladaptive trauma-related beliefs and decrease the intensity of reactions. This case presents concurrent psychopharmacology and cognitive processing therapy for co-occurring posttraumatic stress disorder and AUD. We explore how alcohol use, and emotional avoidance more broadly, become targets for change., (© Copyright 2022 Physicians Postgraduate Press, Inc.)
