Validation of the Persian version of the attitudes toward intellectual disability

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.

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.

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.

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.
