BACKGROUND Effective dissemination of cognitive behavioural therapy (CBT) has been assisted by clearly defined competencies, skills and activities, and validated scales used to measure therapist competence and adherence. However, there is no validated measure of the resource and infrastructure support therapists require to enable them to deliver CBT in line with best practice. AIMS This study aimed to validate an index of resource infrastructure and support for the delivery of CBT. METHOD This study took an existing questionnaire developed by Groom and Delgadillo (2012) and aimed to establish its psychometric properties through expert review and a pilot study. RESULTS This resulted in a shorter questionnaire with good content validity, internal consistency (α = 0.80) and temporal stability (r = 0.74, p < .00). The index consists of six components, and construct validity was demonstrated through positive association with measures of work engagement (r = 0.31, p < .00) and practitioner wellbeing (r = 0.47, p < .00). CONCLUSIONS The questionnaire provides a valid and reliable index of service support for delivering CBT, and is positively related to engagement and wellbeing among CBT practitioners.
