Active Support Measure: a multilevel exploratory factor analysis.

Humphreys et al. (2024) · Journal of intellectual disability research : JIDR 2024
★ The Verdict

The Active Support Measure splits into two staff skill domains, so score engagement and interaction separately during residential audits.

✓ Read this if BCBAs who supervise or consult in group homes for adults with intellectual disability.
✗ Skip if Clinicians focused only on clinic-based skill acquisition or early-intervention home programs.

01Research in Context

01

What this study did

The team looked at the 12-item Active Support Measure. This short checklist rates how well staff help adults with intellectual disability join in everyday activities.

They ran a multilevel exploratory factor analysis on scores from group homes. The goal was to see if the items clump into clear skill areas.

02

What they found

Two clean factors emerged. Factor 1 covers staff efforts to engage residents in tasks. Factor 2 covers warm, respectful talk and body language.

The two-factor model fit the data well. Auditors can now score each domain separately instead of using one total.

03

How this fits with other research

Oliver et al. (2002) showed that active-support training boosts resident engagement, but only for adults with severe ID and no challenging behavior. The new measure gives you a quick way to check if staff still use those skills years later.

Dudley et al. (2019) also built a staff scale with factor analysis, yet theirs targets physical-activity support. Both papers prove brief tools can reliably capture different staff behaviors.

Cashon et al. (2013) validated a 12-item resident satisfaction scale in the same setting. Together the studies let you audit both staff actions and resident happiness with one quick packet.

04

Why it matters

You now have a two-factor lens for supervision. Score Factor 1 when you want more activity participation. Score Factor 2 when you want kinder interactions. Separate feedback helps staff see exactly where to improve, making audits faster and training sharper.

03Original abstract

BACKGROUND: Active Support is a person-centred practice that enables people with intellectual disabilities (IDs) to engage in meaningful activities and social interactions. The Active Support Measure (ASM) is an observational tool designed to measure the quality of support that people with IDs living in supported accommodation services receive from staff. The aim of the study was to explore the underlying constructs of the ASM. METHODS: Multilevel exploratory factor analysis was conducted on ASM data (n = 884 people with IDs across 236 accommodation services) collected during a longitudinal study of Active Support in Australian accommodation services. RESULTS: Multilevel exploratory factor analysis indicated that 12 of the ASM's 15 items loaded on two factors, named Supporting Engagement in Activities and Interacting with the Person. CONCLUSIONS: The 12-item ASM measures two dimensions of the quality of staff support. Both technical and interpersonal skills comprise good Active Support.
