Psychiatric disorders are common in individuals with intellectual disability (ID), but the accurate diagnosis of psychopathology in this population is problematic for a number of reasons, including but not limited to linguistic barriers, difficulty separating symptoms of mental illness from long-term consequences of abnormal brain development, institutionalization, and learned behaviors. In addition, many assessment tools used to diagnose psychopathology in individuals with ID lack reliability or validity for use with this population. The Diagnostic Manual -Intellectual Disability (DM-ID): A Clinical Guide for Diagnosis of Mental Disorders in Persons with Intellectual Disability (Fletcher, Loschen, Stavrakaki, & First, 2007a) is a diagnostic system grounded in evidence-based methods, and supported by expert consensus, that reflects the current best clinical practice to diagnose psychiatric disabilities in persons with an ID. This study converted the behavioral observations found in the DM-ID indicative of psychopathology in individuals with ID with the aim to create a diagnostic screening tool that leads to a more accurate diagnosis of psychiatric disorders in this population. This study describes the development of the items of the Screen for Symptoms of Psychopathology for Individuals with Intellectual Disability (SSP-ID), including critiques by experts in the field. The SSP-ID developed in this study requires further empirical testing to evaluate its validity and reliability. However, once reliability and validity have been established, this tool will make a valuable addition to the DM-ID because it ensures that all possible symptoms of psychopathology specific to ID are not overlooked or misinterpreted, that all relevant diagnostic options are considered, and that the adapted diagnostic criteria in the DM-ID are reviewed prior to making a diagnosis. By taking into consideration the fact that the symptom presentation and manifestation of a psychiatric disorder ma (open full item for complete abstract)
