Development and psychometric properties of the Attitudes Toward Intellectual Disability Questionnaire - Short Form.

Morin et al. (2019) · Journal of intellectual disability research : JIDR 2019
★ The Verdict

The 35-item ATTID-SF keeps the five attitude factors intact and saves time when you need a quick read on how people view intellectual disability.

✓ Read this if BCBAs who run staff training or inclusion programs in schools and day programs.
✗ Skip if Clinicians who already use the full ATTID and have plenty of time.

01Research in Context

01

What this study did

The team trimmed the long Attitudes Toward Intellectual Disability (ATTID) survey down to 35 questions.

They kept the same five attitude areas: knowledge, contact, negative feelings, positive feelings, and social distance.

The short form was tested with a new group of adults to be sure it still measured the same ideas reliably.

02

What they found

The 35-item ATTID-SF held on to the five-factor shape and good reliability.

The authors say the short form is ready to use, but they want other labs to try it too.

03

How this fits with other research

Nikolov et al. (2009) did the same trick with the QABF. They cut 40 questions to 15 and kept the five-function map and strong stats.

Chen et al. (2001) shrank the 73-item ABS-RC to 24 items and still hit near-perfect match scores.

Balboni et al. (2022) later showed the Italian DABS can also save time while keeping Vineland-level accuracy for ID diagnosis.

Together these papers build a clear rule: you can slim ID-related scales without losing signal.

04

Why it matters

Long surveys tire out staff and families. The ATTID-SF gives you attitude data in half the time, so you can spot stigma early and track attitude change after inclusion programs. Swap it in the next staff training cycle or family intake packet.

03Original abstract

Abstract Background Understanding public attitudes towards people with intellectual disability (ID) can help orient activities to promote the social inclusion of this group. The ATTitudes toward Intellectual Disability (ATTID) questionnaire is a validated 67‐item tool used to assess attitudes towards people with ID from a multidimensional perspective. It is based on a five‐factor model tapping into cognitive, emotional and behavioural components of attitudes. In order to facilitate international research, the goal of this study was to develop a short version that would retain the long form's psychometric properties. Methods Analyses were conducted on a sample of 1608 respondents who completed the full‐length ATTID. A four‐step test refinement procedure was used to reduce the number of items. The first two steps involved a Cronbach's alpha analysis. Items retained were then reviewed to assess face validity. Correlations between factors were calculated, and a factor analysis was performed to compare the original and short forms. Results The number of items in the ATTID was reduced from 67 to 35. The short form maintained good overall reliability. The correlational pattern between factors in both the long and short form is generally the same. The factor analysis of the short form showed a similar five‐factor structure with some loss of variance. Conclusions We recommend the short form be used when administration time is an issue, particularly in a research context. Replication studies with new samples are needed to further assess the psychometric properties of the ATTID‐Short Form.
