Diagnostic and Treatment Overshadowing Bias Across Disabilities: Are Rehabilitation Professionals Immune?
The concept of diagnostic overshadowing has historically been applied only to clients with mental retardation. The possibility that diagnostic overshadowing impacts other disability categories was explored in this study. This study examined the robustness of diagnostic overshadowing bias when applied to rehabilitation counselor judgments about clients with physical disabilities, as well clients with mental retardation. A total of 89 rehabilitation professionals were presented with a case scenario which was identical except for the specific disability condition described. The professionals then completed a questionnaire that related to diagnostic impressions and treatment recommendations. Diagnostic overshadowing was exhibited with both mental retardation and physical disabilities. However, no overshadowmg was noted for treatment recommendations.
