Norms of the Attitudes Toward Intellectual Disability Questionnaire

Area of Science:

• Psychology
• Public Health
• Sociology

Background:

• The Attitudes Toward Intellectual Disability Questionnaire (ATTID) measures attitudes towards intellectual disability (ID) using affective, cognitive, and behavioral dimensions.
• Existing research highlights the ATTID's psychometric strengths for diverse adult populations.
• Normative data for the ATTID in general population samples are currently unavailable.

Purpose of the Study:

• To establish normative data for the ATTID based on a representative sample of the Quebec general adult population.
• To provide a benchmark for evaluating attitudes toward intellectual disability (ID) across different demographic groups.
• To facilitate comparisons of attitudes toward ID in various contexts, including public health campaigns and international research.

Main Methods:

• A sample of 1605 adults from the general population of Quebec was recruited.
• The Attitudes Toward Intellectual Disability Questionnaire (ATTID) was administered via phone interviews.
• The sample was stratified to ensure representativeness of the Quebec adult population by gender and age.

Main Results:

• Normative data for the ATTID are presented as percentile scores, stratified by gender and age categories.
• Significant differences in attitudes toward intellectual disability (ID) were observed based on gender and age.
• The influence of gender and age on attitudes varied across the five factors measured by the ATTID.

Conclusions:

• The established norms serve as a vital tool for comparing attitudes toward intellectual disability (ID) across different groups.
• These norms will aid in assessing the impact of interventions and public campaigns aimed at fostering positive attitudes toward individuals with ID.
• The availability of these norms will enable international comparisons of attitudes toward intellectual disability (ID).
