The Integrated Developmental Model of supervison: Scale development and validation procedures.

Despite the growing empirical evidence for developmental models of supervision, the need for reliable, valid assessment procedures for identifying a trainee's level of development exists. This study sought to address this need by administering an instrument designed to assess constructs relevant to C. D. Stoltenberg and U. Delworth's (1987) Integrated Development Model (IDM) to counseling and clinical psychology trainees of varying levels of graduate education, counseling, and supervision experience. Primary data provided support for the IDM and suggested construct validity for the Supervisee Levels Questionnaire—Revised because scores on the instrument differed for certain trainee groups who varied in amount of previous training and experience.
