The validity and reliability of the Turkish Version of Attitudes Toward Intellectual Disability Questionnaire (ATTID) – Short Form (eng)

Abstract

INTRODUCTION: Despite the excessive healthcare needs, persons with Intellectual Disability (ID) experience an inadequate access to healthcare services. Evaluating the attitudes of health personnel and community toward ID is important in terms of determining the factors affecting the social inclusion of persons with ID and the effectiveness of the services provided to these persons. The aim of this study was to adapt the Attitudes Toward Intellectual Disability Questionnaire (ATTID)-Short Form to Turkish, which consists of cognitive, emotional and behavioural dimensions of attitude, and to evaluate its validity and reliability. METHODS: This study is a methodological type of research conducted on 1-6th grade medical faculty students studying in 2019. Exploratory factor analysis, simultaneously applied scale correlation analysis, Cronbach's alpha and test-retest correlation analysis were carried out in data analyses. RESULTS: In this study, as a result of the exploratory factor analysis, five factors were determined whose items were compatible with the original items of the questionnaire. The factor loads of the items in the five factors were between 0.33-0.80, and five factors explained 52.49% of the total variance. As a result of the reliability analysis, the Cronbach's alpha coefficient in the factors of the Turkish version of the ATTID-Short Form varied between 0.76-0.87, and it was 0.88 in the whole questionnaire. DISCUSSION AND CONCLUSION: Analyses conducted to determine the validity and reliability of the Turkish version of the ATTID-Short Form demonstrated that the questionnaire was accepted as a valid and reliable measurement tool.
