Development and initial validation of the Performance Skills Questionnaire (PSQ).

Orit and colleagues built a new parent form called the Performance Skills Questionnaire (PSQ).

Parents of preschoolers with mild or moderate developmental delay filled it out twice.

The team checked if answers stayed the same over time and if the scores matched other measures.

The PSQ showed strong, consistent answers across both rounds.

Scores lined up with other tests of daily-living skills and differed from unrelated tests.

The authors say the tool is ready for clinical use.

Rosenberg et al. (2010) did almost the same work in the same year. They made the Environmental Restriction Questionnaire for the same age group and also found good reliability and validity. Together the two papers give BCBAs a matched pair: one form captures what the child can do (PSQ), the other captures what the world lets them do (ERQ).

McQuaid et al. (2024) later showed that parent ratings on the Social Responsiveness Scale stay stable from preschool to school age. That backs the idea that parent reports like the PSQ can be trusted over time.

Barrett et al. (2015) validated the DCDQ-Italian for older children. Their motor-coordination checklist and the PSQ both had strong test-retest numbers, showing parent forms work across different skill areas and cultures.

You now have a free, brief parent form that reliably maps a preschooler’s everyday skills. Pair it with the ERQ to see if low scores come from child limits or environmental blocks. Use the results to pick goals that fit real-life settings and to show parents clear before-and-after numbers.
