Validation of the attitudes toward intellectual disability: ATTID questionnaire.

Morin et al. (2013) · Journal of intellectual disability research : JIDR 2013
★ The Verdict

The ATTID is a ready-to-use five-factor survey that reliably tracks attitude change toward people with intellectual disability.

✓ Read this if BCBAs who train staff, run anti-stigma programs, or need pre-post attitude data for grant reports.
✗ Skip if Clinicians looking only for quick staff screening; the full ATTID is longer than newer tools like BAID.

01Research in Context

01

What this study did

The team built a new survey called the ATTID. It measures how people feel about individuals with intellectual disability.

They gave the survey to adults and ran math checks. They wanted five clear attitude areas and steady scores over time.

02

What they found

The survey held together. The five attitude factors stayed solid and scores were reliable week to week.

That means you can use the ATTID before and after a stigma class and trust any change you see.

03

How this fits with other research

Scior et al. (2011) made the shorter IDLS first. The IDLS tracks basic knowledge and stigma. The ATTID widens the lens by adding feelings and action items.

Van der Molen et al. (2010) built the ADS for any disability. The ATTID keeps the tight focus on intellectual disability and gives you more detail with its five factors.

McQuaid et al. (2024) later trimmed the idea down again. Their BAID scale measures physician bias with just 12 items, showing the field keeps refining tools for specific users.

04

Why it matters

If you run staff training or school talks, the ATTID gives you a free, proven yardstick. Give it before the session, teach, give it again, and show the difference in numbers. The five scores tell you exactly which attitude piece moved, so you can tweak your next class.

03Original abstract

BACKGROUND: Individuals with an intellectual disability (ID) continue to experience major obstacles towards social, educational and vocational integration. Negative attitudes toward persons with ID has remained relevant over time and has led to discrimination and stigma. OBJECTIVE: The present study describes the development of a new questionnaire for tapping into the general population's attitudes toward individuals with ID and addresses its psychometric properties. METHODS: Adopting a multidimensional perspective, the Attitudes Toward Intellectual Disability Questionnaire (ATTID) was developed from a series of previously validated instruments and principles from the Montreal Declaration on Intellectual Disability (2004). The ATTID was administered by phone to 1605 randomly selected adult men and women, stratified by region in the Province of Quebec, Canada. RESULTS: The ATTID yielded a five-factor structure overlapping the tri-partite model of attitudes. The cognitive component was represented by two factors: knowledge of capacity and rights and knowledge of causes of ID. The affective component tapped into two factors: discomfort and sensitivity/compassion. Finally, the behavioural component emerged as a single factor. The ATTID had good internal consistency with Cronbach's alpha coefficients ranging from 0.59 to 0.89 for the five factors and of 0.92 for the overall questionnaire. Test-retest reliability yielded correlations from 0.62 to 0.83 for the five factors. CONCLUSION: The ATTID can be used to measure attitudes among different populations and allows comparisons over time within the same population as a function of various intervention strategies for de-stigmatising ID.
