Abstract: Objectives: This study aimed to determine the extent to which Cognitive Behavioral Therapy for Insomnia (CBT-I) influences participant willingness to seek treatment for behavioral health conditions. We hypothesized that, relative to sleep hygiene control, CBT-I would be associated with increased willingness to seek treatment for alcohol use, depression, anxiety, PTSD, and chronic pain. Since all participants had insomnia, we also tested CBT-I effects on willingness to seek treatment for residual or future episodes of insomnia. Method: Data were derived from a randomized controlled trial comparing the efficacy of CBT-I to sleep hygiene control among heavy-drinking Veterans with insomnia (N=70; 57 men, 13 women; age M=37.6, SD=9.4). Willingness to seek treatment was measured on a scale from 0 (strongly disagree) to 4 (strongly agree). Results: At the end of treatment, across both groups, participants reported most willingness to seek treatment for insomnia (M=3.08, SD=1.04), followed by chronic pain (M=2.82, SD=1.21), anxiety (M=2.76, SD=1.24), depression (M=2.75, SD=1.29), PTSD (M=2.61, SD=1.27), and alcohol use (M=2.51, SD=1.19). Relative to those in sleep hygiene, CBT-I participants reported increased willingness to seek treatment for insomnia [F(1,48)=10.25, p=.002, d=0.86] and chronic pain [F(1,48)=5.76, p=.02, d=0.60]. No other group-by-time interactions were significant. Conclusions: CBT-I does increase willingness for future treatment, but only targeting insomnia and chronic pain. Continued research on how to engage Veterans in evidence-based treatment for common mental health concerns (e.g. alcohol use, depression, anxiety, and PTSD) is needed.
