Integrated primary care (IPC) has received substantial support with its demonstrated ability to improve access to care, quality of care and health outcomes. Although the benefits of IPC are clear, the integration process has met barriers. One barrier is limited understanding of behavioral health professionals’ (BHP) attitudes towards IPC. Better understanding could allow us to improve BHP training and motivation for IPC practice. This study aimed to develop Transtheoretical Model (TTM) measures to assess BHP attitudes toward and readiness to practice IPC using split-half cross-validation procedures. The sample consisted of 319 licensed and practicing BHPs with a stage distribution of Precontemplation 50.6%, Contemplation 2.8%, Preparation 1.6%, Action 6.0%, and Maintenance 39.0%. Exploratory principal components analyses yielded a 2-factor (Pros α=.90; Cons α=.83) 16-item scale for the decisional balance (DCBL) measure, a 1-factor 5-item scale for the self-efficacy (SE) measure (α=.93) and a 2-factor 12-item scale for the IPC Behavior measure (Consultation/Practice Management α=.915; Intervention/Knowledge α=.891). Confirmatory analyses replicated the hypothesized scale structures for DCBL (CFI=.89, AASR=.05, loadings.51-.81), SE (CFI=.90, AASR=.03, loadings .60-.90) and IPC Behavior (CFI=.934, AASR= .04, loadings .63-.91). MANOVA results by stage of change replicated hypothesized patterns for each construct Wilk’s Λ= .55, F(15, 834.09)= 13.55,p
