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. Submissions from researchers, clinicians, and related professionals in the fields of psychology, rehabilitation, special education, kinesiology, 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 welcome. All research and clinical reports should contain sufficient procedural detail so that readers can clearly understand what was done, how it was done, and why the strategy was selected. Rigorously conducted replication studies utilizing group and single-case designs are welcome irrespective of results obtained. In addition, systematic reviews, meta-analyses, and theoretical discussions that contribute substantially to understanding the problems and strengths of persons with developmental and physical disabilities are considered for publication. Authors are encouraged to preregister empirical studies, replications, systematic reviews, and meta-analyses in a relevant public database and to include such information with their submission to the journal. Authors are also encouraged, where possible and applicable, to deposit data that support the findings of their research in a public repository (see detailed “Research Data Policy” module in the journal’s Instructions for Authors). 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.
