A pilot study of behavioral activation for veterans with posttraumatic stress disorder.

A pilot study was conducted to investigate the feasibility and effectiveness of behavioral activation (BA) therapy for veterans with posttraumatic stress disorder (PTSD). Eleven veterans seeking treatment at a Veterans Administration outpatient PTSD clinic were enrolled in the study protocol, consisting of 16-weekly individual sessions of BA. Nine veterans completed the protocol, one participant completed 15 sessions, and one dropped out after one session. Clinician-rated PTSD symptom severity showed significant pre- to posttreatment improvement and was associated with a moderate effect size. A number of participants also were improved on measures of depression and quality of life, but changes did not reach statistical significance. Findings suggest that BA is a well-tolerated, potentially beneficial intervention for veterans with chronic symptoms of PTSD.

Problems assessment for substance using psychiatric patients: development and initial psychometric evaluation.

BACKGROUND: Persons with co-occurring Axis I mental disorders and substance use disorders often experience multiple negative consequences as a result of their substance use. Because no existing measure adequately assesses these population-specific problems, we developed the Problems Assessment for Substance Using Psychiatric Patients (PASUPP). This paper describes the scale development and factor structure, and provides initial reliability and validity evidence for the PASUPP. METHODS: An initial pool of 54 items was assembled by reviewing existing measures for relevant items and generating new items. Then, 239 patients (90% male, 61% White) with documented Axis I psychiatric and current substance use disorders rated the lifetime and last 3-month occurrence of each problem, and completed additional measures of substance use and related functioning. RESULTS: Lifetime endorsements ranged from 31 to 95%, whereas 3-month endorsements ranged from 24 to 78%. Item analyses reduced the set to 50 items. The PASUPP is internally consistent (alpha = 0.97) and unidimensional. Scale validity was suggested by moderate correlation with other measures of substance problem severity. CONCLUSIONS: Promising psychometric properties are reported for a population-specific measure of substance use problems. Such a measure could be useful for initial assessments and outcome evaluations with substance using psychiatric patients.

Feasibility of a skills training approach to reduce substance dependence among individuals with schizophrenia.

A novel treatment for persons who have both schizophrenia and substance abuse was evaluated by incorporating cognitive-behavioral drug relapse prevention strategies into a skills training method originally developed to teach social and independent living skills to patients with schizophrenia. Thirty-four of 56 patients completed treatment and a three-month follow-up assessment. Participants learned substance abuse management skills and reported that they found the treatment relevant, useful, and satisfying, and their drug use decreased. Improvements were noted in medication adherence, psychiatric symptoms, and quality of life. This manual-driven therapy may play an important role in the treatment of substance abuse among patients with schizophrenia.

Test-retest reliability of alcohol measures: is there a difference between internet-based assessment and traditional methods?

This study compared Web-based assessment techniques with traditional paper-based methods of commonly used measures of alcohol use. Test-retest reliabilities were obtained, and tests of validity were conducted. A total of 255 participants were randomly assigned to 1 of 3 conditions: paper-based (P&P), Web-based (Web), or Web-based with interruption (Web-I). Follow-up assessments 1 week later indicated reliabilities ranging from .59 to .93 within all measures and across all assessment methods. Significantly high test-retest reliability coefficients support the use of these measures for research and clinical applications. Furthermore, no significant differences were found between assessment techniques, suggesting that Web-based methods are a suitable alternative to more traditional methods. This cost-efficient alternative has the advantage of minimizing data collection and entry errors while increasing survey accessibility.
