“…Our criteria excluded instruments that only incorporate one general scale that does not differentiate among domains of psychopathology (e.g., the maladaptive behavior section of the Vineland Scales; Sparrow, Balla, & Cicchetti, 1984); does not contain empirically derived psychopathology domains (e.g., part II of the AAMD Adaptive Behavior Scale-School Edition; Lambert, Windmiller, Tharinger, & Cole, 1981); were not developed or adapted for use in children with a broad range of levels of ID (e.g., the Rutter scales; Rutter, Tizard, & Whitmore, 1970; the Child Behavior Checklist, Achenbach, 1991a); were not developed or adjusted for school-aged children (e.g., psychopathology instrument for mentally retarded adults; Matson, Kazdin, & Senatore, 1984;Watson, Aman, & Singh, 1988); cannot be completed by lay informants (e.g., the maladaptive behavior section of the Vineland Scales; Sparrow et al, 1984); and focus only on specific domains of psychopathology (e.g., the Emotional Disorders Ratings Scale for Children with MR; Feinstein, Kaminer, Barrett, & Tylenda, 1988). We refer to Aman (1991) for an overview of excluded instruments.…”

Children, including adolescents, with intellectual disability (ID) are at higher risk than children without ID for developing psychopathology, a term we use to subsume similar terms such as mental illness or health problems, psychiatric or behavior disorders, and behavior and emotional problems. Psychopathology in children with ID is also more likely to go unrecognized and untreated. Psychopathology may have a major effect on their general well-being, personal independence, school and social functioning, and quality of life, as well as on family and other caregivers. The combination of ID and psychopathology can also give rise to further stigmatization, prejudices, and misunderstandings, which may decrease the likelihood of full integration.

“…Independent replications indicate that the PIMRA, in its present form, is inadequate for diagnosing this population (Aman, Watson, Singh, Turbott, & Wilsher, 1986;Linaker & Nitter, 1990;Watson, Aman, & Singh, 1988). Data indicated that most clients meeting the criteria for a personality disorder on the PIMRA also met the criteria for more than one diagnostic category, suggesting that PIMRA is prone to over-identification.…”

Diagnosis and treatment considerations with comorbid developmentally disabled populations

Differential diagnosis in client populations presenting with complexities of developmental disabilities has become a time honored psychodiagnostic practice. Standard practice has been to ignore comorbidity in client groups where mental disorders and retardation coexist. In persons with mental retardation, differential diagnosis prioritizes the many presenting symptoms, identifying a single causation. Attention deficit hyperactivity disorders, mood disorders, pervasive developmental disorders, stereotypic movement disorders, and mental disorders due to a general medical condition often coexist with mental retardation. As mentally retarded populations move from institutional to community residency, comorbidity appears more prevalent, often becoming a client management issue. Dual diagnosis is important in considering treatment plans, obtaining access and funding for services. interdisciplinary communication, and generating epidemiological data.

“…None of the studies were primarily aimed at examining de novo dimensional models of psychopathology. However, two studies did give consideration to the relevance of their findings to the underlying structure of psychopathology (Watson et al, 1988;Sturmey et al, 1996). We believe that the initial data from all 20 studies provides a useful evidence-base to inform future statistical modelling studies.…”

“…Seven studies reported the statistical software package used in the factor analysis; three used the Statistical Package for the Social Sciences (SPSS: (Linaker, 1991;Sturmey et al, 2005;Gerber & Carminati, 2013) and four used the Statistical Analysis System (SAS: Watson et al, 1988;Gustafsson & Sonnander, 2002;Gustafsson & Sonnander, 2005;Janssen & Maes, 2013). None of these seven papers reported the use of the programs for EFA of categorical data in SPSS (CATPCA) and SAS (PRINQUAL).…”

Diagnosing mental ill-health using categorical classification systems has limited validity for clinical practice and research. Dimensions of psychopathology have greater validity than categorical diagnoses but dimensional models have not had a significant impact on our understanding of mental ill-health experienced by adults with intellectual disabilities. This paper systematically reviews the methods and findings from intellectual disabilities studies that use statistical methods to identify dimensions of psychopathology from data collected using structured assessments of psychopathology. The PRISMA framework for systematic review was used to identify studies for inclusion. Study methods were compared to best-practice guidelines on the use of exploratory factor analysis. Data from the 20 studies included suggest that it is possible to use statistical methods to model dimensions of psychopathology experienced by adults with intellectual disabilities. However, none of the studies used methods recommended for the analysis of non-continuous psychopathology data and all 20 studies used statistical methods that produce unstable results that lack reliability. Statistical modelling is a promising methodology to improve our understanding of mental ill-health experienced by adults with intellectual disabilities but future studies should use robust statistical methods to build on the existing evidence base.3
