Is the sequencing of change processes by stage consistent across health problems? A meta-analysis.

Clinicians and researchers applying the transtheoretical model (J.O. Prochaska, C.C. DiClemente, & J.C. Norcross, 1992) to health promotion often assume that relationships of processes and stages observed in smoking cessation can be generalized to other problems. A reanalysis of 47 cross-sectional studies determined that use of change processes varies by stage, but the sequencing of processes is not consistent across health problems. In smoking cessation, cognitive processes were used in earlier stages than were behavioral processes. In exercise adoption and diet change, use of behavioral and cognitive processes increased together. Results for substance abuse and psychotherapy were less consistent. Substituting new behaviors, making a commitment, considering consequences, seeking information, controlling cues, and using rewards varied most by stage. Future longitudinal studies should assess these processes as potential mediators of lifestyle change.

Effectiveness of national implementation of prolonged exposure therapy in Veterans Affairs care.

IMPORTANCE Posttraumatic stress disorder (PTSD) is a pervasive and often debilitating condition that affects many individuals in the general population and military service members. Effective treatments for PTSD are greatly needed for both veterans returning from Iraq and Afghanistan and veterans of other eras. Prolonged exposure (PE) therapy has been shown to be highly efficacious in clinical trials involving women with noncombat trauma, but there are limited data on its effectiveness in real-world clinical practice settings and with veterans. OBJECTIVE To evaluate the effectiveness of PE as implemented with veterans with PTSD in a large health care system. DESIGN, SETTING, AND PARTICIPANTS This evaluation included 1931 veterans treated by 804 clinicians participating in the Department of Veterans Affairs (VA) PE Training Program. After completing a 4-day experiential PE training workshop, clinicians implemented PE (while receiving consultation) with a minimum of 2 veteran patients who had a primary diagnosis of PTSD. MAIN OUTCOMES AND MEASURES Changes in PTSD and depression symptoms were assessed with the PTSD Checklist and the Beck Depression Inventory II, measured at baseline and at the final treatment session. Multiple and single imputation were used to estimate the posttest scores of patients who left treatment before completing 8 sessions. Demographic predictors of treatment dropout were also examined. RESULTS Intent-to-treat analyses indicate that PE is effective in reducing symptoms of both PTSD (pre-post d = 0.87) and depression (pre-post d = 0.66), with effect sizes comparable to those reported in previous efficacy trials. The proportion of patients screening positive for PTSD on the PTSD Checklist decreased from 87.6% to 46.2%. CONCLUSIONS Clinically significant reductions in PTSD symptoms were achieved among male and female veterans of all war eras and veterans with combat-related and non-combat-related PTSD. Results also indicate that PE is effective in reducing depression symptoms, even though depression is not a direct target of the treatment.

VA Practice Patterns and Practice Guidelines for Treating Posttraumatic Stress Disorder

Little is known about how recent ISTSS practice guidelines (E. B. Foa, T. M. Keane, & M. J. Friedman, 2000) compare with prevailing PTSD treatment practices for veterans. Prior to guideline dissemination, clinicians in 6 VA medical centers were surveyed in 1999 (n = 321) and in 2001 (n = 271) regarding their use of various assessment and treatment procedures. Practices most consistent with guideline recommendations included psychoeducation, coping skills training, attention to trust issues, depression and substance use screening, and prescribing of SSRIs, anticonvulsants, and trazodone. PTSD and trauma assessment, anger management, and sleep hygiene practices were provided less consistently. Exposure therapy was rarely used. Additional research is needed on training, clinical resources, and organizational factors that may influence VA implementation of guideline recommendations.

Relationships among PTSD symptoms, social support, and support source in veterans with chronic PTSD

The present study examined the temporal relationship between posttraumatic stress disorder (PTSD) and social support among 128 male veterans treated for chronic PTSD. Level of perceived interpersonal support and stressors were assessed at two time points (6 months apart) for four different potential sources of support: spouse, relatives, nonveteran friends, and veteran peers. Veteran peers provided relatively high perceived support and little interpersonal stress. Spouses were seen as both interpersonal resources and sources of interpersonal stress. More severe PTSD symptoms at Time 1 predicted greater erosion in perceived support from nonveteran friends, but not from relatives. Contrary to expectations, initial levels of perceived support and stressors did not predict the course of chronic PTSD symptoms.

Using administrative data to identify mental illness: what approach is best?

The authors estimated the validity of algorithms for identification of mental health conditions (MHCs) in administrative data for the 133 068 diabetic patients who used Veterans Health Administration (VHA) nationally in 1998 and responded to the 1999 Large Health Survey of Veteran Enrollees. They compared various algorithms for identification of MHCs from International Classification of Diseases, 9th Revision (ICD-9) codes with self-reported depression, posttraumatic stress disorder, or schizophrenia from the survey. Positive predictive value (PPV) and negative predictive value (NPV) for identification of MHC varied by algorithm (0.65-0.86, 0.68-0.77, respectively). PPV was optimized by requiring ≥2 instances of MHC ICD-9 codes or by only accepting codes from mental health visits. NPV was optimized by supplementing VHA data with Medicare data. Findings inform efforts to identify MHC in quality improvement programs that assess health care disparities. When using administrative data in mental health studies, researchers should consider the nature of their research question in choosing algorithms for MHC identification.

Sixand Ten-Item Indexes of Psychological Distress Based on the Symptom Checist-90:

Clinicians, provider organizations, and researchers need simple and valid measures to monitor mental health treatment outcomes. This article describes development of 6and 10-item indexes of psychological distress based on the Symptom Checklist-90 (SCL-90). A review of eight factor-analytic studies identified SCL-90 items most indicative of overall distress. Convergent validity of two new indexes and the previously developed SCL-10 were compared in an archival sample of posttraumatic stress disorder patients (n = 323). One index, the SCL-6, was further validated with archival data on substance abuse patients (n = 3,014 and n = 316) and hospital staff (n = 542). The three brief indexes had similar convergent validity, correlating .87 to .97 with the SCL-90 and Brief Symptom Inventory, .49 to .76 with other symptom scales, and .46 to .73 with changes in other symptom measures over time. These results indicate the concise, easily administered indexes are valid indicators of psychological distress.

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.

Causes of death among male veterans who received residential treatment for PTSD.

Previous studies have shown elevated mortality among psychiatric and substance abusing patients, including veterans with PTSD. Although early studies showed elevated deaths from external causes among Vietnam veterans in the early postwar years, more recent studies have also shown increased health problems among veterans with PTSD. This study compared mortality due to behavioral causes versus other diseases among 1,866 male veterans treated for PTSD. Death certificates obtained for 110 veterans indicated behavioral causes accounted for 62.4% of deaths, standardized mortality ratio = 3.4–5.5, including accidents (29.4%), chronic substance abuse (14.7%), and intentional death by suicide, homicide, or police (13.8%). Results suggest possible opportunities to improve outcomes of this at-risk patient population through harm reduction interventions and improved continuity of care.

Preschoolers' pretend play and theory of mind: The role of jointly constructed pretence

As they develop, preschool children make great strides in their ability to take and understand multiple perspectives, sometimes referred to as the development of a theory of mind. Recently, the role of pretend play in that development has been investigated. In the present study, 2 experiments were conducted with 85 preschoolers. Children were observed during naturalistic spontaneous play on three independent occasions and then tested on their ability to differentiate appearance and reality and to understand false belief. Results suggest that children who displayed more jointly constructed pretence in their play better distinguished the apparent and real identity of visually deceptive objects. This was true after controlling for age and, in the second experiment, verbal intelligence. Solitary pretend play was not as strongly associated with theory of mind ability. These findings suggest that makebelieve play, particularly socially interactive role play, develops concurrently with childrens understanding of multiple representational tasks.

Predicting high-risk behaviors in veterans with posttraumatic stress disorder.

The present study sought to identify posttraumatic stress disorder (PTSD) patients at high risk for negative behavioral outcomes (violence, suicide attempts, and substance use). The Mississippi Scale for Combat-Related PTSD, the Beck Depression Inventory, and demographic and behavioral data from 409 male combat veterans who completed a VA residential rehabilitation program for PTSD were analyzed using signal detection methods (receiver operating characteristics). A validation sample (N = 221) was then used to test interactions identified in the signal detection analyses. The best predictors of behaviors at follow-up were those same behaviors shortly before intake, followed by depressive and PTSD symptoms. However, for each of the models other than that for hard drug use, cutoffs determined at the symptom level did not lend themselves to replication. Recent high-risk behaviors, rather than patients’ history, appear to be more predictive of high-risk behaviors postdischarge.
