38-5 Development and Validation of a Supervisory Relationship Scale
The purpose of this study was to develop a valid and reliable measure of supervisory relationship from the perspective of supervisees. Qualitative data obtained from a previous study and information generated from a review of the literature were used to construct a 78 item self-report questionnaire measure. After an evaluation by six professionals who used a constructive model to analyze the content validity of the scale, 4 items were combined into 2 and 24 items with CVI lower than .80 were deleted, resulting in a 52-item original version of Supervisory Relationship Scale (SRS). The scale was administered to 198 counseling supervisees with diverse background characteristics on gender, training level, affiliated universities, institutions, and geographical areas. The principal components analysis identified seven components for the construct of SRS. Due to having only one single item, the seventh component was removed. Finally the SRS was comprised of six components and 51 items in total. The components were labeled: ”Safe Supervisory Environment and Personal Characteristics”, ”Trustworthy Supervision and Professional Traits”, ”Supervision Intervention Facilitating Cognitive Development”, ”Formative Feedback and Role Modeling”, ”Helping Awareness and Situated Intervening”, and ”Supervisor Self Disclosure” . The amount of variance in SRS explained by the six factors was 61.715%. The results of the analyses for the scale's concurrent validity, internal consistency and split-half reliability were favorable. The SRS demonstrated good concurrent validity (γ=.871, p＜.001), high internal consistency (α=.978), and good splithalf reliability (γxx=.959). On the basis of the findings of the study, the applications of this instrument for counselor and supervisor training and for future research are forwarded.
