Understanding factors that contribute to an individual’s decision to use an innovation can increase the public health impact of innovations in children’s mental health services. Objective. This study examined whether and to what extent therapists’ innovation-specific judgements (e.g., innovation is easy to use, socially desirable) were associated with intentions to use an innovation using constructs from one of the most robust theories of innovation use–the Unified Theory of Acceptance and Use of Technology (UTAUT). Method. Two aims were addressed using data collected from 95 therapists and 28 supervisors who participated in a multi-site cluster randomized trial. Therapists used either a coordinated set of knowledge resources or traditional knowledge resources. For aim one, a multiple regression analysis was conducted to explore the proportion of variance in use intentions explained by the UTAUT constructs. For aim two, a series of multilevel models were constructed to assess the predictive utility of the UTAUT relative to individual and organizational variables in the literature (e.g., attitudes towards evidence-based practice, organizational climate). Results. Innovation-specific judgements explained approximately 74% of the variance in therapist intentions to use their respective knowledge resources. Additionally, innovation-specific judgements explained more than twice the variance in use intentions relative to the individual and organizational variables, and remained statistically significant predictors of use intentions after controlling for individual and organizational variables. In contrast, the individual and organizational variables only explained an additional 3% of the variance in use intentions after accounting for the innovation-specific judgements and were no longer statistically significant. Conclusions. This study demonstrated that therapists’ innovation-specific judgements can be strong indicators of intentions to use an innovation. Results are discussed within the context of implementation interventions.
