“…This is consistent with previous research showing most participants in clinical trials improved after 12 sessions (Hansen et al, 2002). It may be that fewer than 10 sessions is not sufficient for reduction of symptoms with individuals who have been exposed to such extreme events.…”

High levels of trauma-related psychological distress have been documented among ethnically diverse refugees. As the number of refugees worldwide continues to grow, determining the efficacy of established methods of trauma-focused therapy for this population is crucial. This meta-analysis examined the results of randomized controlled trials of psychotherapeutic intervention for traumatized adult refugees. Comparisons of 13 trauma-focused therapies to control groups from 12 studies were included in the analysis. The aggregate effect size for the primary outcome, posttraumatic stress disorder (PTSD), was large in magnitude, Hedge's g = .91, p < .001, 95% CI [.56, 1.52]. The aggregate effect size for depression, assessed in 9 studies, was also large g = .63, p < .001, 95% CI [.35, .92]. We used metaregression to evaluate potential moderators of the PTSD effect size. Number of sessions significantly predicted magnitude of the effect size, and studies that utilized an active control group (e.g., supportive counseling) had significantly smaller effect size than those with a passive control group. There was no difference in outcome for studies where an interpreter was used to facilitate sessions and those where no interpreter was used. There also was no difference in outcome based on type of PTSD assessment. Results provide evidence in the efficacy of trauma-focused models for treating refugees, and also shed light on important areas for future research.

“…First, it may be the case that the present sample of trainee clinicians, on average, possesses relatively high EL A second, perhaps more likely, explanation is that the clinicians who were less confident in their abilities (including El) and/or their clients' outcomes chose not to participate in the study (though none indicated this when declining participation). The general trends of these findings, however, appear to be consistent with the broader literature reviews (e.g., Hansen, Lambert, & Forman, 2002;Shimokawa, Lambert, & Smart, 2010), in that the greatest percentages of clients experienced no change.…”

Narrative descriptions of incompetent trainee clinicians suggest that such trainees may have unacceptably low emotional intelligence (EI), which is consistent with a lack of the requisite baseline competencies necessary for more advanced practicum competency development. There further remains a need to identify standardized instruments that could facilitate gate-keeping decisions and support trainee development. The purpose of this study, which included 32 trainee clinicians and their respective 133 clients, was to characterize trainee EI while taking into account the potential effect (s) of personality factors. Results revealed that neuroticism, as measured by Costa and McCrae's five-factor inventory (P. T. Costa, Jr. and R. R. McCrae, 1992, NEO PI-R professional manual: Revised NEO Personality Inventory {NEO Pl-R) and NEO Five-Factor Inventory (NEO-FFI), Odessa, FL, Psychological Assessment Resources), significantly predicted client change (as measured by the Outcome Questionnaire 45.2; M. J. Lambert et al., 1996, Administration and Scoring Manual for the OQ-45.2, Stevenson, MD, American Professional Credentialing Services), with EI, as measured by the MSCEIT (J. D. Mayer, P. Salovey, & D. Caruso, 2002, Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) user's manual. Toronto, ON, Canada: Multi-Health Systems), moderating this relationship. The model accounted for 46% of the variance in client outcomes. Drawing on the private self-consciousness literature, an explanation for the valuable interaction between EI and neuroticism in producing client change is discussed and implications for training, practice, and future research are identified.

“…Thus, offering stepped care to patients with low social functioning might to a certain extent adjust for differences in treatment outcome compared to patients with high social functioning. This may reflect a treatment doseeresponse effect, as the content of the guided self-help program and the FtF-CBT had a considerable overlap, adding up to a longer period with treatment and support (Hansen, Lambert, & Forman, 2002).…”
