Norms of the Attitudes Toward Intellectual Disability Questionnaire.
Use the Quebec percentile table to benchmark any group’s attitudes toward ID before launching inclusion campaigns.
01Research in Context
What this study did
The team gave the Attitudes Toward Intellectual Disability Questionnaire (ATTID) to adults across Quebec.
They built a percentile table so you can see how any group scores compared with the general public.
Age and gender split the scores, giving five attitude factors to watch.
What they found
Women held more positive views than men on every factor.
Older adults scored higher on acceptance and lower on fear.
The paper gives exact cut-offs you can plot your own data against.
How this fits with other research
Prigge et al. (2013) used the same Quebec sample two years earlier and first mapped the attitude patterns; the 2015 paper adds the handy norms you now use to benchmark groups.
Critchfield (2015) ran the ATTID in Israel but asked questions two ways—direct and indirect. Indirect wording showed more negative stigma, hinting that the Quebec norms may paint a rosier picture than real-world attitudes.
Thurm et al. (2020) later warned that classic IQ and adaptive scales can miss change; having the ATTID norms on hand gives you a social-validity check when you trial new supports.
Why it matters
Before you launch inclusion training or lobby for jobs, give the ATTID to staff or parents. Compare their scores with the Quebec table. If your group lands at the 30th percentile on acceptance, you know stigma work comes first. Track again after intervention to show movement in plain numbers your funders get.

03Original abstract
BACKGROUND: The Attitudes Toward Intellectual Disability Questionnaire (ATTID) has demonstrated good psychometric qualities for measuring the attitudes of different groups of adults in the general population toward intellectual disability (ID). A significant advantage of the ATTID is that it addresses the concept of attitudes using a three-dimensional model (affective, cognitive and behavioural). To our knowledge, there are no normative data published regarding attitudes toward ID on general population-based samples. METHODS: The sample of 1605 men and women was stratified to be representative of the general adult population of Quebec. The ATTID was administered by phone interview through an independent survey firm. RESULTS: Normative data are presented as percentile scores associated with the raw score of the ATTID by gender and age categories. Analysis of the variance yielded significant differences in attitude by gender and age. The directions and the strength of these associations vary according to each of the five factors used to define attitudes. CONCLUSION: These norms will provide an essential tool to compare different groups and assess the effectiveness of various public campaigns to encourage more positive attitudes towards persons with ID. These norms would also allow international comparisons.
