Implementing Computer-Based Psychotherapy among Veterans in Outpatient Treatment for Substance Use Disorders
psychotherapy interventions (CBPIs) are increasingly offered as first-level
access to evidence-based mental health treatment. However, their implementation
has not been evaluated in public-sector outpatient settings.
evidence-based CBPI for insomnia was implemented with provider and patient
education sessions, on-site Internet access, and clinician telephone support.
Persons receiving care at a Veterans Health Administration substance abuse
treatment clinic were screened for chronic insomnia and offered CBPI access.
The feasibility of this strategy was evaluated in a pre-post design, which
assessed engagement and completion rates, participant-reported acceptability,
and clinical outcomes.
veterans referred, 51 enrolled in the program, of whom 22 (43%) completed all
sessions, 13 (26%) partially completed the program, and 16 (31%) did not
engage. There were no statistically significant differences between these three
groups in baseline characteristics. In the total sample, Insomnia Severity
Index (ISI) scores decreased (improved) by 32% (mean±SD of 6.3±6.2 points,
t=6.82, df=44, p<.001). Veterans who completed all six sessions displayed
clinically and statistically significant improvements on the ISI compared with those
who did not engage, as shown in a regression analysis that controlled for
baseline insomnia severity, time between assessments, and sedative-hypnotic
medication use (F=3.87, df=4 and 40, p≤.004). Among all participants, 67%
agreed that they would engage in another CBPI in the future. When questioned
about potential barriers, 36% of the full sample endorsed a preference for
strategy of brief provider and patient education, on-site Internet access, and
telephone support was feasible and effective for implementing CBPIs in
outpatient substance abuse treatment settings for veterans.
