Abstract

Abstract : Objective: We examined the psychometric properties of the Dialectical Behavior Therapy (DBT) Barriers to Implementation Scale (BTI‐S). Method: Participants were clinicians completing a bipartite training, separated by 6 months of self‐study, to implement DBT. Exploratory factor analysis was conducted with data collected from the initial training period ( N = 790), while confirmatory factor analysis was based on data from the final training period ( N = 660). Results: The final model included 26 items and 4 factors with overall acceptable fit, χ 2 (293, N = 660) = 460.989, p < .001, comparative fit index = .909, Tucker‐Lewis index = .899, root mean square root mean square error of approximation (90% confidence interval) = .015. The internal reliability of the scores was low (range = .56 to .72). Conclusion: The final model fits reasonably well and measures four domains considered important for implementation of DBT. However, the low reliability of the scores indicates that the BTI‐S would be improved with further development.
