Counselor trainees' stress and coping resources have the potential to influence the relationships formed with supervisors and clients. Two hundred thirty two (N = 232) Master-level counselor trainees completed surveys designed to measure perceived stress, coping resources, the working alliance, and the supervisory working alliance. Participants completed a demographic questionnaire, the Working Alliance Inventory-Short Form Therapist Version (WAI-S; Tracey & Kokotovic, 1989), the Supervisory Working Alliance Inventory-Trainee Version (SWAI-T; Efstation, Patton, & Kardash, 1990), the Perceived Stress Scale-Short Form (PSS; Cohen, Kamarck, & Mermelstein, 1983), and the Coping Resources Inventory for Stress-Short Form (CRIS; Curlette & Matheny, 2008). The working alliance was negatively correlated with Perceived Stress ( r = -0.25, p less than 0.01) and positively correlated with the coping resources Situational Control, ( r = 0.23, p less than 0.01), Emotional Control ( r = 0.18, p = 0.01), Social Support From Family ( r = 0.19, p less than 0.01), Mental Tension Control ( r = 0.18, p less than 0.01), and Making Plans ( r = 0.15, p less than 0.05). The supervisory working alliance was negatively correlated with Perceived Stress ( r = -0.23, p less than 0.01) and positively correlated with the coping resources Situational Control ( r = 0.17, p less than 0.01), Emotional Control ( r = 0.18, p less than 0.01), Social Support From Friends ( r = 0.14, p less than 0.05), Mental Tension Control ( r = 0.22, p less than 0.01), Asserting One's Rights ( r = 0.13, p less than 0.05), and Trusting Oneself ( r = 0.14, p less than 0.05). After controlling for the primary internship setting, Stress (delta R[superscript 2] = 0.055, beta = -0.21, p less than 0.001) and Social Support from Family (delta R[superscript 2] = 0.021, beta = -0.21, p less than 0.025) explained 7.6% of the variance in the working alliance, F (10, 221) = 3.71, p less than 0.001. After controlling for the number of counseling sessions and total number of weekly individual counseling hours, Perceived Stress (delta R[superscript 2] = 0.047, beta = -0.14, p less than 0.10) and Situational Control (delta R[superscript 2] = 0.026, beta = 0.18, p less than 0.025) explained 7.3% of the variance in the supervisory working alliance, F (4, 170) = 7.73, p less than 0.001. Implications for counselor training and implications for research are discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
