The Journal of Developmental and Physical Disabilities is an interdisciplinary forum for the publication of original research and clinical reports from a variety of fields serving persons with developmental and physical disabilities. Efforts by professionals in the fields of psychology, rehabilitation, special education, counseling, social work, psychiatry, nursing, and rehabilitation medicine are considered. Investigations utilizing group comparisons as well as single-case experimental designs are of primary interest. In addition, case studies that are of particular clinical relevance or that describe innovative evaluation and intervention techniques are published. All research and clinical reports should contain sufficient detail so that readers can clearly understand what was done, how it was done, and why the strategy was selected. In addition, reviews and theoretical discussions that contribute substantially to our understanding of the problems and strengths of persons with developmental and physical disabilities are also published. In response to the need for increased clinical and research endeavors with persons with developmental and physical disabilities, the journal is cross-categorical and unbiased methodologically.
