  Purpose

This project assesses the usability and feasibility of a multi-behavioral computerized, tailored intervention (CTI) or expert system delivered via the Internet for veterans with Post-Traumatic Stress symptoms. Three behavioral health risk factors, (1) smoking, (2) depression, and (3) stress, that are associated with Post-Traumatic Stress Disorder (PTSD), are included in the Computerized, Tailored Intervention (CTI) system. The project adapts and modifies an existing CTI system built on the Transtheoretical Model of Behavior Change (TTM) to make it relevant to a veteran population. The system has been successfully utilized with general adult populations. The study utilizes methods that are characteristic of a product development project. Each of the four project phases are sequential and build upon the results of the previous phase. Phase 1 focuses on the review of current CTI programs on smoking cessation, stress management, and depression prevention, and integrating them into a multi-behavioral program for application with veterans. Phase 2 includes the development and adaptation of text-based feedback messages and multimedia components for smoking cessation, stress management, and depression prevention for veterans. Initial testing of the modified CTI programs commences in Phase 3. Cognitive and usability testing with veterans are performed, and additional modifications to the behavioral modules are made based on the test results. Phase 4 focuses on a feasibility study to test the multi-behavioral CTI system with veterans online.

Primary Outcome Measures:
  • Change in PCL-M Score (PTSD Symptom Checklist-Military [PCL-M], Weathers et al., 1993) [ Time Frame: Change in PCL-M score from baseline (T1) to final 3 mos. follow-up (T3) ] [ Designated as safety issue: No ]
    Developed by researchers at the VA National Center for PTSD, PCL is a self-report questionnaire that consists of 17 questions that map directly onto DSM-IV criteria for PTSD. Respondents are asked how often they have been bothered by each symptom in the past month on a 5-point Likert scale (1=not at all to 5=extremely). Previous research has shown internal consistency coefficients were high for the total scale (.97) and for each subscale (.92 - .93). Test-retest reliability over 2-3 days was shown to be .96. Scores can range from 17-85, with a score of 48 typically indicating PTSD in military populations. The National Center for PTSD recommends using 5 points as a minimum threshold for determining whether an individual has responded to treatment and 10 points as a minimum threshold for determining whether the improvement is clinically meaningful. A higher score indicates more PTSD symptoms, therefore, a score reduction from T1 to T3 is a better outcome than an increase.


Secondary Outcome Measures:
  • Change in QOLS Score T1 to T3 (Quality of Life Scale [QOLS], Flanagan, 1978, 1982) [ Time Frame: Change in QOLS score from baseline (T1) to final 3 mos. follow-up (T3) ] [ Designated as safety issue: No ]
    The QOLS contains 16 items that represent five conceptual domains of quality of life. QOLS was developed with more consideration to cultural diversity and individual perspectives than other commonly used measures. It uses a unique 7-item Likert scale that allows responses regarding different aspects of life to range from "delightful" to "terrible". It has been found to be internally consistent with alpha from .82 to .92 and showed high test-retest reliability over 3-weeks (r = 0.78 to r = 0 .84). The QOLS is scored by adding up the score on each item to yield a total score for the instrument. Scores can range from 16 to 112. Previous validation research showed that patients who participated in a treatment program and rated their symptoms as improved by 60% or gained on average 7 to 8 points on the QOLS total score. A higher QOLS score indicates better quality of life, therefore, a positive score change is a better outcome.

  • Change in PSS From T1 to T3 (The Perceived Stress Scale [PSS] Cohen, Kamarck, & Mermelstein, 1983) [ Time Frame: Change in PSS score from baseline (T1) to final 3 mos. follow-up (T3) ] [ Designated as safety issue: No ]
    The PSS is the most widely used psychological instrument for measuring the perception of stress. It is a 10-item questionnaire that measures an individual's subjective evaluation the stressfulness of situations in their life in the past month. Items are designed to tap how unpredictable, uncontrollable, and overloaded respondents find their lives. The items are of a general nature and relatively free of content specific to any subpopulation. Internal consistency reliability of the PSS has been shown to be moderate (Cronbach alpha coefficient =.78) and that it has good test-re-test reliability. Scores can range from 0-40 as items are scored 1-4 points each. A higher score indicates more stress, so a negative change from baseline (T1)to 3-month follow-up (T3) is a better outcome.

  • Change in PHQ-8 From T1-T3 (Patient Health Questionnaire [PHQ-8], Kroenke & Spitzer, 2002; Spitzer, Kroenke, & Williams, 1999) [ Time Frame: Change in PHQ-8 score from baseline (T1) to final 3 mos. follow-up (T3) ] [ Designated as safety issue: No ]
    The PHQ-9 is the self-administered depression module of the Patient Health Questionnaire that assesses common mental disorders. Eight of the 9 items in the scale are included in the Depression Prevention Assessment and is also known as the PHQ-8. Item 9, which assesses suicidality has been omitted in the online version. The PHQ-8 has been shown to have a sensitivity of 81% and specificity of 99% for scores 15 and above in diagnosing major depression, with a positive predictive value of 94%. Scores range from 0 to 24, with 10-14 indicating minor depression, 15-19 moderately severe major depression, and >19 indicating sever major depression. An initial drop of 5 points is considered adequate treatment response for 3 counseling sessions over 4-6 weeks. A higher score indicates more depression, so a reduction in score from baseline (T1) to 3-month follow-up (T3) is a better outcome.

Arms Assigned Interventions
Experimental: All STR2IVE Participants
All participants who met study criteria, consented and were enrolled, were asked to complete online assessments at three timepoints(baseline, 1-month, and 3-months) and complete 2 or more behavioral programs each month. Behavioral programs and assessments were provided online via the Multibehavioral, Computerized Tailored Intervention STR2IVE.
Behavioral: Multibehavioral, Computerized Tailored Intervention STR2IVE
All participants were provided with the same multibehavioral CTI system and chose two or three behavior programs to complete (smoking cessation, stress management, and/or depression prevention)monthly. They were asked to complete an assessments at baseline, 30-days, and 90-days. They were allowed to access the system workbook anytime but they must wait a minimum of 25 days between assessments and programs at time points 1 and 2, and 55 days between time points 2 and 3.
