The role of mental health and challenging behaviour in the quality of life in people with intellectual disabilities in Spain

Abstract

Purpose

The purpose of this paper is to determine the relation between quality of life (QoL), mental illness, challenging behaviour and institutionalisation in an adult population with intellectual disabilities (ID).

Design/methodology/approach

The study assessed the QoL and its conditioning factors in 142 subjects with different degrees of ID. The GENCAT and Quality of Life in Late Stage Dementia scale were used to evaluate QoL, the Psychiatric Assessment Schedule for Adults with Developmental Disability and Diagnostic Assessment for the Severely Handicapped-II scale to assess mental illness and the Inventory for Client and aetiology Planning scale to assess challenging behaviour.

Findings

Individuals who live in residential care homes were found to have significantly impaired QoL (<0.001). Individuals with challenging behaviour presented significantly lower QoL, regardless of ID aethiology and degree, while psychiatric disorders did not seem to have a direct influence on individual QoL.

Originality/value

This paper provides new insight into the importance of challenging behaviour and psychiatric disorders in the QoL of individuals with ID.
