In an attempt to facilitate the dissemination and regular implementation of behaviour treatments in real-world settings, research has examined staff attitudes that may pose barriers to these treatments. The purpose of the study reported in this paper is to examine the construct validity of perceived organisational barriers to behavioural programs. One hundred and eighteen staff working in community-based treatment programs for adults and children with severe mental illness completed the Barriers to the Implementation of Behavior Therapy Test. An analysis from a previous study (Corrigan, Kwartarini, & Pramana, 1992) identified two reliable and valid factors that suggested perceived organisational barriers: institutional constraints and insufficient collegial support. Results of a confirmatory factor analysis on data from this study supported the earlier factor structure. Research participants also completed team functioning measures of individual staff burnout, collegial network satisfaction, organisational culture, and team leadership. Attitudes about institutional constraints and insufficient collegial support were found to be associated with burnout, collegial network satisfaction, and organisational culture. Strategies for disseminating behavioural programs must target organisational barriers too.
