Content:
A total of n=57 items were developed after reviewing pertinent literature, collecting "expert opinion" and discussions within the project team. Nine content domains proposed for the test were mapped against collaborative practice and teamwork attributes found in existing instruments developed by Baggs (1994); Way, et al., (2000); Millward & Jeffries, 2001; Temkin-Greener, et al., (2004); Lemieux & Jeffries, (2001); and Sutter, et al. (2009).
Response Process:
During the first pilot test, after completing the CPAT items, respondents completed 10 addition questions concerning the clarity of statements, time and effort to complete, clarity of instructions, item content, adequacy of scale, and relevance to their practice setting. Modifications, deletions, and additions were made as a result of this feedback, and also based on results from the exploratory factor analysis (see below). The most significant additions were 5 new items that measure the level of patient involvement in the team's practice.
Internal Structure:
Results of the exploratory factor analysis for the original 57 items found support for 7 domains (factors), each with an eigenvalue of around 3.0, which collectively explained roughly 50% of the variance. Cronbach's alpha estimates were were adequate to very good (between 0.70 and 0.90) for the 7 factors. The confirmatory factor analysis for the revised 56 item instrument reported good results for the Normed Fit Index and the Comparative Fit Index, based on 8 factors. Cronbach's alpha estimates were adequate to good for each factor (0.67 - 0.89). It was unclear what proportion of score variance was accounted for by these 8 factors; nor were their Eigenvalues reported.
