Quality of Life in Adults With Intellectual Disability: Observation‐Measurement Findings and Social Validity Among Direct Service Providers

Luiselli et al. (2026) · Behavioral Interventions 2026
★ The Verdict

A one-page DSP checklist can reliably spot quality-of-life highs and lows in adult group homes.

✓ Read this if BCBAs who supervise residential services for adults with intellectual disability.
✗ Skip if Clinicians who work only in day programs or family homes.

01Research in Context

01

What this study did

Luiselli and colleagues built a short form for direct-support staff to watch and rate quality-of-life moments.

They tried it in adult group homes for people with intellectual disability. Observers checked items like social contact, activity choice, and comfort.

The team then asked the staff if the form felt useful and easy.

02

What they found

Staff agreed with each other on most items, so the form proved reliable.

Ratings leaned positive, showing residents often experienced good moments.

Staff also said the tool was helpful and quick to use.

03

How this fits with other research

Joslyn et al. (2018) used a similar checklist in secure forensic homes and likewise found good observer agreement. Their earlier work gives confidence the method travels across settings.

Leung et al. (2010) and Boets et al. (2011) both built short staff scales for service needs and therapy notes. All four papers show practitioners can complete valid paper tools during routine work.

Hagopian et al. (2005) paint a darker picture: residents with profound disability received only 3.8 hours of mostly passive leisure each weekend. The new Luiselli form shows positive staff views, but the 2005 data remind us low activity levels still lurk beneath upbeat ratings.

Why it matters

You now have a free, staff-friendly checklist that tracks real-time quality of life. Add it to monthly supervision, pick one low-scoring area, and plan an activity to boost it. Five extra minutes of observation can steer goals and show families clear data.

03Original abstract

ABSTRACT The quality of life (QoL) of persons with intellectual disability should be a fundamental concern for behavior analysis practitioners. In this pilot study, we designed an observation‐measurement form for direct service providers (DSPs) to record QoL indicators at two residential homes operated by a human services organization. The observation‐measurement form had good interobserver agreement, yielded many positive ratings of 12 QoL indicators, and suggested several areas of QoL that could be improved. Also, the DSPs completed a social validity questionnaire that revealed desirable impressions of QoL among adults living in the homes. Though preliminary, the study suggests a methodology for measuring QoL objectively at behavior analysis service organizations and monitoring QoL systematically by practitioners who support persons with intellectual disability.
