Comparison of the validity of four fall-related psychological measures in a community-based falls risk screening.

We examined the measurement properties offall-related psychological instruments with a sample of 133 older adults (M age = 74.4 years, SD = 9.4). Measures included the Comprehensive Falls Risk Screening Instrument, Falls-efficacy Scale-International (FES-I), Activities-specific Balance Confidence (ABC), modified Survey ofActivities and Fear ofFalling in the Elderly (mSAFFE), Consequences of Falling (CoF), Physical Activity Scale for the Elderly (PASE), and 36-Item Short-Form Health Survey (SF-36). The FES-I, ABC, mSAFFE, and CoF were significantly correlated with each othe, with SF-36, and with mobility. The ABC and mSAFFE were significantly correlated with PASE. The ABC differentiated between fallers and nonfallers and predicted total falls risk. Findings can assist with the selection of psychological instruments in a falls risk screening context.

Measurement of fall-related psychological constructs among independent-living older adults: a review of the research literature.

OBJECTIVES: Falls and the fall-related psychological concerns associated with these events pose a serious public health problem among aging adults. The measurement of fall-related psychological concerns can serve as important endpoints for fall prevention programs, yet there is some confusion regarding the best method of defining and measuring fall-related psychological constructs. Consequently, greater attention should be devoted to investigating fall-related psychological constructs and their measurement. Therefore, the purpose of this paper was to review the published research literature on the measurement of fall-related psychological constructs among independent-living older adults. METHOD: Electronic searches of PubMed, EBSCO, Academic Search Premier, PsycINFO, CINAHL and online library catalogs were conducted using search terms including but not limited to 'fear of falling', 'falls efficacy', 'fall-related self-efficacy', 'balance confidence', 'fall-related psychological outcome(s)' and 'independent-living'. RESULTS: Each of these constructs is unique, yet instruments are often employed to measure constructs other than those the instruments were designed to assess. Inconsistencies were also revealed both within and across studies in terms of providing evidence of validity for these instruments. CONCLUSION: Fall-related psychological constructs, although similar in nature, are unique constructs and should be measured as such.

Construct validation of physical activity surveys in culturally diverse older adults: a comparison of four commonly used questionnaires.

The purpose of this study was to establish validity evidence of four physical activity (PA) questionnaires in culturally diverse older adults by comparing self-report PA with performance-based physical function. Participants were 54 older adults who completed the Continuous Scale Physical Functional Performance 10-item Test (CS-PFP10), Physical Activity Scale for the Elderly (PASE), HAMPS Physical Activity Questionnaire for Older Adults, Yale Physical Activity Survey (YPAS), and modified Baecke questionnaire. The total PASE score, three outcome scores for the CHAMPS, and three summary indices for the YPAS were significantly correlated with total CS-PFP10 score. The modified Baecke exhibited no correlations with CS-PFP10 scores. The PASE, CHAMPS, and YPAS appear to be the most valid PA self-report questionnaires for culturally diverse older adults.
