This study compared the effectiveness of the Wellness Model of Supervision (WELMS; Lenz & Smith, 2010) against other models of supervision for developing the wellness constructs, total personal wellness, and helping skills among CITs. Participants in were 44 masters level Caucasian counseling students (9 men) completing their practicum and internship requirements in a CACREP accredited counseling program who were Caucasian (N = 27) Hispanic/ Latino (N = 12) and African American (N = 5) young adults (M = 32 years, SD = 9.96) of predominately heterosexual affectional orientation (96%). Pretest and Posttest measures of wellness construct, total wellness, and counseling skills were analyzed using a Split Plot Analysis of Variance. Results indicated that participants in the WELMS condition developed their personal construct of wellness and total wellness noticeably more when compared to participants receiving other models of supervision. Additionally, no differences in counseling skills development were noted between groups suggesting that the WELMS does not negate essential functions of supervisory and training practices. Implications for counselor development, meeting ethical requirements for self-care and monitoring, demonstrating student learning outcomes, and conducting empirical evaluations of supervisory practices are provided. The following are appended: (1) Preliminary Questionnaire; and (2) Counseling Skills Scale-Modified.
