Validation of the Persian version of the attitudes toward intellectual disability

Abstract

Background: Attitudes toward individuals with intellectual disability (ID) are the most important factor affecting their social integration and can cause them to experience a sense of achievement or discrimination. The present study aimed to evaluate the latent factor structure and validity of the Persian version of the Attitudes toward Intellectual Disability (ATTID) Short-Form questionnaire.

Methods: The latent factor structure of the Persian version of the ATTID Short-Form was established in a convenient sample of the general population (N = 280) in Iran. The structural validity and temporal reliability, internal consistency and confirmatory factor analysis were evaluated. Data analysis was done with SPSS v23 Windows edition and R v4.2.1.

Results: The Persian version of the ATTID Short-Form was shown to have a five-factor structure: discomfort, knowledge of capacity, interaction, sensitivity and knowledge of cause. The structure was appropriately fit according to the fit indices (χ²(485) = 530.12), (P-value = 0.077). All the subscales had good temporal reliability.

Conclusions: Findings suggest that the Persian version of the Short-Form of ATTID is a brief, valid and reliable measure that can be used in research and clinical practice.
