This guide is intended to assist rehabilitation counselors, school guidance personnel, and others involved in administering and interpreting the results of the Vocational Decision-Making Interview (VDMI). (The VDMI is a structured interview instrument that was developed to facilitate the assessment of an individual's vocational decision-making capabilities, identification of an interviewee's unique decision-making needs, and development of an individual vocational decision-making profile.) The first part of the guide traces the development of the VDMI; summarizes selected research results with the VDMI; outlines its structure; and describes its special applications in the following areas: vocational evaluation, general counseling and guidance, Individualized Education Program (IEP)) and Individualized Written Rehabilitation Plan (IWRP) planning, determination of group characteristics, and program development. Discussed next are the following aspects of VDMI administration: preparing the interviewing environment (interviewer and interviewee preparation), selecting an appropriate and qualified interviewer and heeding certain interviewing cautions, and administering and scoring the VDMI. The third section, which deals with interpreting VDMI results, covers clinical versus open-ended interpretations, normative comparisons, and procedures for profiling subcategories. The fourth section consists of tables of norms. A profile sheet and a copy of the VDMI are included with the manual. (MN)
