Mesker et al. (2025) · Journal of intellectual disability research : JIDR 2025
★ The Verdict

A 134-adult study shows a new self-report emotional-development questionnaire is almost ready for clinical use.

✓ Read this if BCBAs assessing emotional skills in adults with mild–moderate ID.
✗ Skip if Clinicians serving only children or adults with severe/profound ID.

01Research in Context

01

What this study did

The team built a new self-report questionnaire that tracks emotional growth in adults with mild or moderate intellectual disability.

They tested it with 134 adults. The questions use plain words and picture cues so people can answer on their own.

This is the first time the Scale of Emotional Development was turned into a form that the person with ID fills out instead of a caregiver.

02

What they found

The new tool showed good reliability and validity, but a handful of items confused some adults.

The authors say the questionnaire works, yet it needs a few wording fixes before clinics adopt it.

03

How this fits with other research

Yuwiler et al. (1992) and Schaal (1996) proved adults with ID can reliably self-report mood when you adapt child scales. Mesker et al. (2025) now widen the lens from single moods to full emotional development.

Wilson et al. (2023) and Pellicano et al. (2022) recently validated self-report wellbeing and depression scales for youth with ID. The new questionnaire mirrors their method but targets adults and the broader construct of emotional growth.

Timberlake (1993) used caregiver reports of the Children’s Depression Inventory for adults with ID. The current study flips the perspective: it keeps the adult voice front and center, showing the field is moving from proxy to self-report.

04

Why it matters

You now have a draft tool that lets adults with mild–moderate ID describe their own emotional skills. Use it during intake to spot growth areas, but double-check confusing items before scoring. When the final version lands, you can replace caregiver guesses with the client’s own words.

03Original abstract

BACKGROUND: In people with intellectual disabilities, emotional development progresses more slowly or stagnates, which can result in challenging behaviours. The Scale of Emotional Development-Questionnaire was designed to chart people's own emotional development, providing insight into basic emotional needs and resilience, while reducing prejudice, enhancing self-awareness and improving emotional expression. METHODS: The questionnaire was completed by 134 participants with moderate to borderline intellectual disabilities. Reliability, validity, internal structure and item performance were analysed to identify areas for improvement. RESULTS: Preliminary analyses indicated the questionnaire captures key aspects of emotional development, with most items showing strong factor loadings (51.79%). However, multiple items may require refinement due to moderate loadings (30.00%), low loadings (18.21%), limited variance (3.93%) and negative-low correlations. CONCLUSION: The Scale of Emotional Development-Questionnaire is a promising self-report interview of emotional development, complementing the proxy perspective of the Scale of Emotional Development-Short. The findings highlight areas for improvement and the need for further research post-revision.
