The purpose of this correlational, explanatory mixed methods study was to explore subject matter experts’ (SME) perceptions and justifications of those perceptions, regarding how assumptions and fundamental core constructs for the OA model and the VdTMoCA model compare with each other for use within the practice of occupational therapy. Fourteen SMEs (n = 9 OA; n = 5 VdTMoCA) participated in an online quantitative survey. Nine of those SMEs agreed to participate in a qualitative interview (n = 5 OA; n = 4 VdTMoCA). Quantitative outcome measures included a researcher created survey containing paired assumption and key core constructs and a “shared” statement from both OA and VdTMoCA, forming an item group. SMEs indicated agreement or disagreement to each statement using a 1 – 4 Likert scale. Qualitative data included interview data informed by the survey responses. Descriptive statistics, intraclass correlation coefficient (ICC), and Cronbach alpha (a) were used to analyze the quantitative data. Qualitative data thematic analysis including descriptive and values coding methods were conducted. The ICC and Cronbach alpha analysis revealed an excellent level of agreement across all item group statements at .91 (p <.001), and a good/excellent level of absolute agreement at .88 (p <.001). The qualitative data revealed three major themes: terminology and meanings of terms used, cultural applicability of models and the need for review and timely revision of models. The need for continued alignment with current trends in practice and world events were revealed. Results indicate that OA and VdTMoCA are similar and comparable practice models based on assumptions and key core constructs.
