How Does Tele-Mental Health Affect Group Therapy Process? Secondary Analysis of a Noninferiority Trial

OBJECTIVE Video teleconferencing (VTC) is used for mental health treatment delivery to geographically remote, underserved populations. However, few studies have examined how VTC affects individual or group psychotherapy processes. This study compares process variables such as therapeutic alliance and attrition among participants receiving anger management group therapy either through traditional face-to-face delivery or by VTC. METHOD The current study represents secondary analyses of a randomized noninferiority trial (Morland et al., in press) in which clinical effectiveness of VTC delivery proved noninferior to in-person delivery. Participants were male veterans (N = 112) with posttraumatic stress disorder (PTSD) and moderate to severe anger problems. The present study examined potential differences in process variables, including therapeutic alliance, satisfaction, treatment credibility, attendance, homework completion, and attrition. RESULTS No significant differences were found between the two modalities on most process variables. However, individuals in the VTC condition exhibited lower alliance with the group leader than those in the in-person condition. Mean self-leader alliance scores were 4.2 (SD = 0.8) and 4.5 (SD = 0.4), respectively, where 5 represents strongly agree and 4 represents agree with positive statements about the relationship, suggesting that participants in both conditions felt reasonably strong alliance in absolute terms. Individuals who had stronger alliance tended to have better anger outcomes, yet the effect was not strong enough to result in the VTC condition producing inferior aggregate outcomes. CONCLUSION Our findings suggest that even if group psychotherapy via VTC differs in subtle ways from in-person delivery, VTC is a viable and effective means of delivering psychotherapy.

Identifying patterns of symptom change during a randomized controlled trial of cognitive processing therapy for military-related posttraumatic stress disorder.

Cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) has been shown to reduce symptoms of PTSD in a veteran population. This study explored patterns of self-reported symptom change during CPT. Veterans (N = 60) with PTSD were randomized to receive CPT immediately or after 10 weeks. We hypothesized that those treated immediately would evidence initial symptom stability followed by decline compared with those who waited, whose PTSD symptoms would remain stable. The best model fit based on deviance statistics and Bayesian information criteria comparisons was one in which participants treated immediately showed more rapid initial decline followed by a slower rate of PTSD symptom improvement relative to those who waited, who showed a stable level of symptomatology. Findings suggest that CPT produces quick and maintained improvements in veterans. The effect sizes for change between those who received CPT immediately and those who waited were approximately medium sized. Implications of findings are discussed.

“Strength at Home” Group Intervention for Military Populations Engaging in Intimate Partner Violence: Pilot Findings

In this brief report, we present information on the Strength at Home intervention to treat male active duty or military veteran perpetrators of intimate partner violence (IPV) as well as preliminary pilot study findings. Strength at Home is a 12-session cognitive-behavioral group intervention developed by the authors that is based on a social information processing model of IPV perpetration. Six men referred to two intervention groups and five collateral female partners participated in this pilot study. Findings indicated large reductions for most indices of physical and psychological IPV from pre-treatment to 6-month follow-up. These initial results are promising though the small sample size and other study limitations preclude our ability to draw firm conclusions.

Changes in Social Adjustment With Cognitive Processing Therapy: Effects of Treatment and Association With PTSD Symptom Change

The current study sought to determine if different spheres of social adjustment, social and leisure, family, and work and income improved immediately following a course of cognitive processing therapy (CPT) when compared with those on a waiting list in a sample of 46 U.S. veterans diagnosed with posttraumatic stress disorder (PTSD). We also sought to determine whether changes in different PTSD symptom clusters were associated with changes in these spheres of social adjustment. Overall social adjustment, extended family relationships, and housework completion significantly improved in the CPT versus waiting-list condition, η(2) = .08 to .11. Hierarchical multiple regression analyses revealed that improvements in total clinician-rated PTSD symptoms were associated with improvements in overall social and housework adjustment. When changes in reexperiencing, avoidance, emotional numbing, and hyperarousal were all in the model accounting for changes in total social adjustment, improvements in emotional numbing symptoms were associated with improvements in overall social, extended family, and housework adjustment (β = .38 to .55). In addition, improvements in avoidance symptoms were associated with improvements in housework adjustment (β = .30), but associated with declines in extended family adjustment (β = -.34). Results suggest that it is important to consider the extent to which PTSD treatments effectively reduce specific types of symptoms, particularly emotional numbing and avoidance, to generally improve social adjustment.

A Randomized Controlled Clinical Trial of the Strength at Home Men’s Program for Partner Violence in Military Veterans

OBJECTIVE We evaluated the efficacy of the Strength at Home Mens Program (SAH-M), a trauma-informed group intervention based on a social information processing model to end intimate partner violence (IPV) use in a sample of veterans/service members and their partners. To date, no randomized controlled trial has supported the efficacy of an IPV intervention in this population. METHOD Participants included 135 male veterans/service members and 111 female partners. Recruitment was conducted from February 2010 through August 2013, and participation occurred within 2 Department of Veterans Affairs hospitals. Male participants completed an initial assessment that included diagnostic interviews and measures of physical and psychological IPV using the Revised Conflict Tactics Scales and were randomly assigned to an enhanced treatment as usual (ETAU) condition or SAH-M. Those randomized to SAH-M were enrolled in this 12-week group immediately after baseline. Those randomized to ETAU received clinical referrals and resources for mental health treatment and IPV services. All male participants were reassessed 3 and 6 months after baseline. Female partners completed phone assessments at the same intervals that were focused both on IPV and on the provision of safety information and clinical referrals. RESULTS Primary analyses using hierarchical linear modeling indicated significant time-by-condition effects such that SAH-M participants compared with ETAU participants evidenced greater reductions in physical and psychological IPV use (β = -0.135 [SE = 0.061], P = .029; β = -0.304 [SE = 0.135], P = .026; respectively). Additional analyses of a measure that disaggregated forms of psychological IPV showed that SAH-M, relative to ETAU, reduced controlling behaviors involving isolation and monitoring of the partner (β = -0.072 [SE = 0.027], P = .010). CONCLUSIONS Results provide support for the efficacy of SAH-M in reducing and ending IPV in male veterans and service members. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01435512.

Cognitive-behavioral conjoint therapy for PTSD improves various PTSD symptoms and trauma-related cognitions: Results from a randomized controlled trial.

Numerous studies document an association between posttraumatic stress disorder (PTSD) and impairments in intimate relationship functioning, and there is evidence that PTSD symptoms and associated impairments are improved by cognitive-behavioral conjoint therapy for PTSD (CBCT for PTSD; Monson & Fredman, 2012). The present study investigated changes across treatment in clinician-rated PTSD symptom clusters and patient-rated trauma-related cognitions in a randomized controlled trial comparing CBCT for PTSD with waitlist in a sample of 40 individuals with PTSD and their partners (N = 40; Monson et al., 2012). Compared with waitlist, patients who received CBCT for PTSD immediately demonstrated greater improvements in all PTSD symptom clusters, trauma-related beliefs, and guilt cognitions (Hedges gs -.33 to -1.51). Results suggest that CBCT for PTSD improves all PTSD symptom clusters and trauma-related cognitions among individuals with PTSD and further supports the value of utilizing a couple-based approach to the treatment of PTSD.

Examining trauma and posttraumatic stress disorder symptoms in court-mandated intimate partner violence perpetrators

There is a dearth of empirical literature characterizing the various forms of trauma experienced by men court mandated to intervention for intimate partner violence (IPV) perpetration. We investigated the potentially traumatic events (PTEs) experienced by men (N = 217) court mandated to enroll in a 41-week group IPV perpetrator program, as well as the relationships between PTEs, posttraumatic stress disorder (PTSD) symptoms, and IPV. Findings indicated that 94% of participants reported experiencing at least 1 PTE in their lifetime, and participants experienced an average of over 6 out of 14 types of PTEs. A significant association was found between the number of PTEs experienced and frequency of self-reported perpetration of physical and psychological IPV. PTSD symptoms were also related to both forms of IPV perpetration and mediated the relationship between experiencing PTEs and psychological IPV perpetration. Our findings have implications for understanding how trauma and PTSD symptoms may increase risk for IPV and for developing trauma-informed interventions for this population.

Associations between functioning and PTSD symptom clusters in a dismantling trial of cognitive processing therapy in female interpersonal violence survivors

This study conducted secondary analyses of a published trial and sought to determine if different domains of psychosocial functioning (e.g., daily living, work, nonfamily relationships) improved following trauma-focused treatment for posttraumatic stress disorder (PTSD). Cognitive processing therapy (CPT), an empirically supported treatment that involves evaluating trauma-related beliefs and written trauma accounts, was compared to its components: CPT without the written accounts or written accounts only in a sample of 78 women with PTSD secondary to interpersonal violence. Overall and individual domains of functioning significantly improved with treatment and results were similar across treatment groups, Fs (2, 150) ≥ 11.87, ps < .001. Additionally, we investigated whether changes in different PTSD symptom clusters were associated with outcomes in domains of psychosocial functioning, after collapsing across treatment condition. Multiple hierarchical linear regression analyses revealed that overall clinician-assessed PTSD symptom reduction was associated with outcomes in all domains of functioning, βs = .44 to .68, ps < .001. Additionally, improvements in the emotional numbing symptom cluster were associated with outcomes in the nonfamily relationships domain, β = .42, p < .001, and improvements in the hyperarousal symptom cluster were associated with outcomes in the overall, daily living, and household tasks domains, βs = .34 to .39, ps < .01. Results suggest that it may be important to monitor improvements in emotional numbing and hyperarousal symptoms throughout treatment to increase the likelihood of changes in psychosocial functioning.

Couple Treatment for Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) affects not only the people suffering from the disorder but also those surrounding them. PTSD is one of the mental health difficulties most strongly associated with relationship distress (Whisman et al. 2000); it has a strong association with a range of family problems, including mental health difficulties in partners and children (Monson et al. 2009; Renshaw et al. 2011; Taft et al. 2011). PTSD can elicit responses from friends and family that are well-meaning but may maintain the symptoms of PTSD, such as helping the individual with PTSD avoid reminders of the trauma, which may over time erode these relationships and place increased burden on family members, leading to negative mental health outcomes (Caska and Renshaw 2011). These accommodative behaviors may also reinforce avoidance associated with PTSD (Figley 1989). Consistent with research documenting that negative social interactions in the wake of trauma are among the most robust risk factors for PTSD (e.g., see Wagner et al. under review for a review), negative family interactions have been linked to poorer individual cognitive-behavioral therapy outcomes (Monson et al. 2005; Tarrier et al. 1999). Moreover, individual evidence-based treatments for PTSD do not consistently improve relational functioning (e.g., Galovski et al. 2005; Monson et al. 2012a, b, c; Lunney and Schnurr 2007). Consequently, there have been efforts to develop and test dyadic treatments that improve relational functioning and PTSD and, in some cases, also improve the health and well-being of partners. The current chapter describes different ways to conceptualize couple treatment in the case of PTSD and reviews the efficacy of these interventions.

Use and Experience of Recent Intimate Partner Violence Among Women Veterans Who Deployed to Iraq and Afghanistan

Background: Women veterans may be at high risk for intimate partner violence (IPV), which increases susceptibility for negative physical and mental health. IPV experiences and use have not previously been studied among the newest generation of women veterans who deployed to the conflicts in Iraq and Afghanistan. Method: This study examined the correlates of IPV in a sample of 102 women veterans who had deployed to the conflicts in Iraq or Afghanistan and who were in current intimate relationships. Using an anonymous web-based survey, participants completed measures of combat and sexual harassment exposure during deployment, measures of mental health and substance abuse, intimate relationship satisfaction, and recent IPV. Results: Results indicated that 63% of the sample reported experiencing any IPV in the past 6 months, whereas 73% reported using IPV toward their partner in the past 6 months. Linear regressions indicated intimate relationship satisfaction explained significant variance in recent psychological IPV, whereas alcohol misuse and recent psychological IPV experiences explained significant variance in physical IPV experiences and use and sexual IPV experiences. Conclusion: Women veterans in this study reported high levels of recent IPV experiences as well as the use of IPV. Results suggest the need to assess for both IPV use and IPV experiences in medical settings, and that for some women veterans, IPV prevention that focuses on healthy relationship functioning may be beneficial.
