Effect of Peer Victimization on the Long-Term Mental Health Status among Adults Users of Intellectual Disability Services: A Longitudinal Follow-Up Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19074196. [PMID: 35409878 PMCID: PMC8998512 DOI: 10.3390/ijerph19074196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 03/18/2022] [Accepted: 03/29/2022] [Indexed: 02/04/2023]
Abstract
Caregiving for mental health among people with intellectual disabilities (IDs) in the ID services was reported as insufficient. The purposes of this study were to investigate five types of peer victimization (PV) experiences among adults with ID using ID services, and to gain a deeper understanding of the influence of PV experience on adults with ID’s long-term mental health status. A one-year longitudinal follow-up study was conducted from eight long-term care ID services (n = 176). Logistic regression analysis was applied to variables comprising personal characteristics, various types of PV experience and polyvictimization to predict period prevalence of psychiatric symptoms. The data indicated that nearly one-third of individuals with ID experienced at least one psychiatric symptom. The three most common psychiatric symptoms prevalent after one year were adjustment disorder, anxiety disorder, and somatoform disorder. Over the 1-year study period, approximately 40% of adults with ID reported experiencing PV. The most frequently reported types of PV were physical force (26%) and verbal victimization (22%). Polyvictimization was experienced by approximately a quarter of adults with ID. The findings suggest that PV is a common experience among adults in ID services. Thus, for a clearer understanding of mental health risks, caregivers should pay attention to adults with ID who experienced PV.

Melville CA, Johnson PCD, Smiley E, Simpson N, McConnachie A, Purves D, Osugo M, Cooper SA. Statistical modelling studies examining the dimensional structure of psychopathology experienced by adults with intellectual disabilities: Systematic review. RESEARCH IN DEVELOPMENTAL DISABILITIES 2016; 53-54:1-10. [PMID: 26852278 DOI: 10.1016/j.ridd.2016.01.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2015] [Revised: 12/22/2015] [Accepted: 01/25/2016] [Indexed: 06/05/2023]
Abstract
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 in the general population, but dimensional models have not had a significant impact on our understanding of mental ill-health and problem behaviours 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.

Abstract
Psychopathology prior to the last four decades was generally viewed as a set of problems and disorders that did not occur in persons with intellectual disabilities (ID). That notion now seems very antiquated. In no small part, a revolutionary development of scales worldwide has occurred for the assessment of emotional problems in persons with ID. The first standardized test to emerge was the Psychopathology Instrument for Mentally Retarded Adults (PIMRA) in 1984. Since that time, an impressive number of measures of general psychopathology have emerged for adults and children as well as for persons across the full range of levels of ID. The purpose of this review was to provide a description of available measures, to review papers published on these measures, and to discuss emerging trends in test development. The trends in this body of information for enhancing differential diagnosis of psychopathology in persons with ID are discussed.

Bakken TL, Helverschou SB, Eilertsen DE, Heggelund T, Myrbakk E, Martinsen H. Psychiatric disorders in adolescents and adults with autism and intellectual disability: a representative study in one county in Norway. RESEARCH IN DEVELOPMENTAL DISABILITIES 2010; 31:1669-1677. [PMID: 20493660 DOI: 10.1016/j.ridd.2010.04.009] [Citation(s) in RCA: 83] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2010] [Accepted: 04/19/2010] [Indexed: 05/29/2023]
Abstract
UNLABELLED Few studies assess psychiatric disorders in representative samples of individuals with autism and ID. Symptoms of autism and psychiatric disorders have been confounded. PAC, a conceptually analysed and validated screening instrument, was used. AIMS Assess prevalence of psychiatric disorders in individuals with intellectual disability only (ID-only) and with combination of autism and ID (autism). Sixty-two (autism) and 132 (ID-only) participants were screened for psychiatric disorders with the Psychopathology in Autism Checklist (PAC); included general adjustment problems (GAP), and severe adjustment problems (SGAP) in one county in Norway. Psychosis, depression, anxiety, and OCD were addressed. Both SGAP and a high psychiatric disorder score were required to screen a psychiatric disorder. "Diagnostic overlap" was defined as more than one psychiatric disorder concurrent with autism. Psychiatric disorders and SGAP were found to be high both in the autism (53.2%) and ID-only group (17.4%). More than 50% of the autism and approximately 20% of ID-only group had SGAP. The differences were significant. The autism-psychiatric disorder interaction was significant. The largest differences between the prevalence in the autism and the ID-only group were shown in individuals with anxiety. The majority of the individuals in both study groups were afflicted with more than one psychiatric disorder. About 60% were found to have more than one disorder. The individuals with more severe psychiatric symptoms had higher degrees of diagnostic overlap. Having an intellectual disability seem to imply high risk for developing adjustment problems, and it seems especially difficult for individuals with autism to master every-day challenges.
