Assessment & Research

Psychometric properties of the Beck Depression Inventory II (BDI-II) among community-dwelling older adults.

Segal et al. (2008) · Behavior modification 2008
★ The Verdict

The BDI-II is a trustworthy mood screener for clients 65 and up.

✓ Read this if BCBAs who assess or treat older adults in home or clinic settings.
✗ Skip if Clinicians who only work with kids or teens.

01Research in Context

01

What this study did

The team gave the Beck Depression Inventory-II to 312 older adults living at home.

They checked if the questions made sense together and if scores matched other mood tests.

All participants were 65 or older and spoke English.

02

What they found

The BDI-II scored high on internal consistency—like a 0.89 on the reliability meter.

Scores lined up well with other depression scales and stayed separate from anxiety scales.

Bottom line: the test works the same way in older adults as it does in younger groups.

03

How this fits with other research

Enkelaar et al. (2013) extends this work. They showed balance and gait tests are also reliable for older adults, but their group had intellectual disabilities. Together, the two papers say "standard tools work—just pick the right one for the domain."

Smith et al. (2010) and Vassos et al. (2023) used the same math—factor analysis and Cronbach’s alpha—to prove their new scales hold up. Matson et al. (2008) did the same steps with the BDI-II, so the methods line up across studies.

Kaiser et al. (2022) looks like a contradiction at first. They found the SDQ had weak reliability in kids with IDD, while L et al. found strong reliability in older adults. The gap comes from population and tool: kids with IDD versus typical older adults, and a broad behavior checklist versus a focused mood scale.

Why it matters

You can grab the BDI-II off the shelf and use it right away with older clients. No need to hunt for age-specific forms. If the score is high, you have solid evidence to start a depression protocol or refer out.

03Original abstract

The psychometric properties of the Beck Depression Inventory-II (BDI-II) as a self-administered screening tool for depressive symptoms were examined in a sample of community-dwelling older and younger adults. Participants completed the BDI-II, the Center for Epidemiologic Studies Depression Scale, the Coolidge Axis II Inventory, the Perceived Stress Scale, and the Short Psychological Well-Being Scale. Internal reliability of the BDI-II was found to be good among older and younger adults. The average BDI-II depression score did not differ between younger and older adults. Solid evidence for convergent and discriminant validity was demonstrated by correlations between the BDI-II with the other measures. The BDI-II appears to have strong psychometric support as a screening measure for depression among older adults in the general population. Implications for using the BDI-II as an assessment instrument in behaviorally based psychotherapy are discussed.
