“…MCC is commonly measured through counselor self-report, supervisor ratings, client ratings, observer ratings (Worthington, Soth-McNett, & Moreno, 2007), or case conceptualization as a type of performance-based assessment (e.g., Calfa, Van Horne Kerne, & McCarthy, 2013; Ladany, Inman, Constantine, & Hofheinz, 1997; Schomburg & Prieto, 2011); however, MCC has most often been operationalized through the use of self-report measures. Although scholars have noted that self-report MCC may be an important construct (particularly as conceptualized as a type of self-efficacy), it also has considerable limitations when used as the only method of assessing MCC (Lantz, Pieterse, & Taylor, 2020; Wilcox, Franks, Taylor, Monceaux, & Harris, 2020; Constantine & Ladany, 2000; Worthington & Dillon, 2011). Still, self-report remains most widely used, which is arguably due to the ease with which self-report measures can be administered as compared to other methods of assessing MCC.…”
