Validation of the developmental work personality model and scale

The construct of work personality has been linked to the development of effective work behaviors and overall vocational adjustment for individuals with disabilities. One conceptualization of work personality that has received consideration in the rehabilitation research literature is the construct of developmental work personality (DWP). The primary strengths of the DWP model are that it is grounded in developmental, learning, and work theories that have been widely validated with multiple populations in a variety of contexts and that the model is designed to explain components of the work personality, described by Neff as being "semi-autonomous." The purpose of this study is to provide evidence of the psychometric properties of the DWP scale in samples of persons eligible to receive vocational rehabilitation services. The results of this three-phase study reveal empirically defined factors of the scale that correspond to the DWP model, adequate convergent validity measures, and adequate to good internal and temporal reliability coefficients in a sample of students. Recommendations for best use of the model and scale are included.
