BACKGROUND Likert-type scales are increasingly being used among people with intellectual disability (ID). These scales offer an efficient method for capturing a wide range of variance in self-reported attitudes and behaviours. This review is an attempt to evaluate the reliability and validity of Likert-type scales in people with ID. METHODS Fifty-one studies reporting response rates, response bias, reliability and validity of Likert-type scales among adolescents and adults with ID were…

Reliability of a method for establishing the capacity of individuals with an intellectual disability to respond to Likert scales

It is recommended that the pretest protocol be modified to improve its reliability, and this modified version be used with study participants who have an intellectual disability to ascertain the appropriate level of choice to be used for items that use a Likert response format.

The quality of life perceptions of people with intellectual disability and their proxies†

The results indicated that the QOL scores among respondents did not seem to be interchangeable, and different perspectives should be included in QOL assessments.

Reliability and validity of the Dutch version of the Glasgow Anxiety Scale for people with an Intellectual Disability (GAS-ID).

The Dutch version of the GAS-ID is a reliable screening instrument with satisfactory sensitivity, but moderate specificity for anxiety disorders, justifying referral for psychiatric assessment of false-positives.

Adapting Self-Report Measures of Mental Health for Children with Intellectual Disability

Self-report measures of mental health can be completed by children with intellectual disability but may need pilot testing and modifications to make them more appropriate for this population.

Psychometric Properties of Self-reported Quality of Life Measures for People with Intellectual Disabilities: A Systematic Review

This article aimed to review outcome measure instruments of self-reported Quality of Life (QOL) in people with Intellectual Disability (ID). Instruments were identified from five electronic databases

Review: a systematic review of quality of life measures for people with intellectual disabilities and challenging behaviours.

More instruments that measure QOL need to be developed and rigorously validated, especially for high-needs disability populations like those individuals that exhibit challenging behaviour or have severe to profound ID, as it is questionable whether existing measures can be used with these populations.

International Classification of Functioning, Disability and Health categories explored for self-rated participation in Swedish adolescents and adults with a mild intellectual disability.

OBJECTIVE To explore internal consistency and correlations between perceived ability, performance and perceived importance in a preliminary selection of self-reported items representing the

This preliminary study suggests that the GAS-ID offers a psychometrically robust and practical (5-10 min) approach to the appraisal of anxiety in this population of people with intellectual disability.

Use of the Strengths and Difficulties Questionnaire to assess the mental health needs of children and adolescents with intellectual disabilities

The extended SDQ appears to provide a simple robust measure of the mental health needs of children and adolescents with intellectual disabilities.

The Glasgow Social Self‐Efficacy Scale—a new scale for measuring social self‐efficacy in people with intellectual disability

This paper describes the development of the Glasgow Social Self-Efficacy Scale (GSSES) and reports preliminary details of its psychometric properties. The scale was found to have a test–retest

Assessment of Anxiety and Depression in Adolescents with Mental Retardation

Assessment of psychopathology instruments in referred mentally retarded adolescents with a depressive and anxiety disorders found anxiety measures were positively correlated; they correlated with PIMRA and CBCL total scores, as well as with the internalizing score of CBCL.

The Measurement of Stress in People with an Intellectual Disability: A Pilot Study

This research investigates the feasibility of assessing the self‐perceived stress levels of people with mild intellectual disabilities by self‐report. People with intellectual disabilities generally

A Psychometric Evaluation of 4-Point and 6-Point Likert-Type Scales in Relation to Reliability and Validity.

Reliability and validity of 4-point and 6-point scales were assessed using a new model-based ap proach to fit empirical data. Different measurement models were fit by confirmatory factor analyses of

Assessment of depression in persons with mental retardation.

The psychometric characteristics of the Self-Report Depression Questionnaire (SRDQ), a 32-item self-report measure of depressive symptomatology in persons with mental retardation, were examined and criterion-related validity was demonstrated.

Staff and self-reports of health behaviours, somatic complaints, and medications among adults with mild intellectual disability

The results suggest the utility of both self-reports and staff reports among adults with mild ID for identifying areas of health concern as well as targeting areas for further health promotion efforts.
