Notes: N = 144 substance abuse treatment practitioners prior to MI training. Internal consistency reflects Cronbach’s α coefficients. Corrected subscale-scale metric reflects correlation (e.g., r) of the subscale with the full-scale instrument when the subscale is not included in the full-scale instrument score. Corrected item-subscale correlation reflects correlation of the item with the subscale score when the item is not included in the subscale score. Corrected item-scale correlation reflects correlation of the item with the full-scale instrument when the item is not included in the full-scale instrument score.
