This study explored the relationship between certain educational and professional variables that influence the adherence to empirically supported practices in cognitive-behavioral therapy for insomnia (CBT-I). The variables of interest included the practitioner’s level of training as measured by the number of hours of advanced training in CBT-I, the total number of hours practicing CBT-I out of the total annual clinical practice hours, and the total number of years practicing CBT-I. The final variable of interest was treatment preference and practice knowledge. The study used a one-time, cross-sectional, web-based survey. The participants consisted of 165 mental health and medical professionals of various disciplines who were trained in CBT-I. The results suggested that individuals with more training were significantly more likely to apply CBT-I. Practitioners with more training had a higher percentage of CBT-I on their caseloads than those with less training. The total number of training hours did not significantly predict adherence, with all practitioners scoring similarly.
