This systematic review examined how physical activity outcomes were assessed in interventions involving older adults. The authors reviewed 45 articles identified through PubMed, CINAHL, and PsycInfo, considering study design, activity type, assessment methods, and reported reliability and validity. Most studies used self-report measures, which were often not tailored to older adults; device-based studies frequently applied differing cutoff points. Studies using either approach seldom reported their own reliability and validity assessments. The review concludes that inconsistent measurement methods hinder comparisons and supports efforts to standardize assessment in this field.
Key findings
- The review included 45 articles on physical activity intervention assessments among older adults.
- Most studies used self-report measures, which were often not tailored to older adult populations.
- Device-measured studies frequently used varying cutoff points to assess physical activity levels.
- Studies using self-report or device-based approaches seldom reported their own reliability and validity assessments.
Why it matters
Inconsistent outcome measures make it difficult to compare physical activity interventions and draw conclusions about which strategies are effective. More consistent approaches could improve the interpretability of research and support clearer evaluation of intervention outcomes in older adults.
What to keep in mind
The review describes measurement practices across the included articles; the abstract does not report a quantitative synthesis of intervention effects.
