Construct validity of the BESTest, mini-BESTest and briefBESTest in adults aged 50 years and older.

摘要: Abstract Background The Balance Evaluation Systems Test (BESTest) and its two abbreviated versions (mini-BESTest briefBESTest) are functional balance tools that have yet to be validated in middle aged elderly people living the community. Objective Determine construct validity of three BESTest by comparing them with commonly-used measures balance, confidence physical activity, examining their ability discriminate between groups respect falls fall risk. Methods This was a secondary analysis data from 79 adults (mean age 68.7 ± 10.57 years). Pearson correlation coefficients were used examine relationships each measure Activities-Specific Confidence (ABC) scale, Physical Activity Scale for Elderly (PASE), Timed Up Go (TUG) Single Leg Stance (SLS) test. Independent t-tests differences fallers (≥1 previous year) non-fallers individuals classified at low versus high risk using Falls Screening (EFST). Results showed moderate associations ABC scale TUG (r = 0.62–0.67 −0.60 −0.68 respectively), fair (r = 0.33–0.40) PASE (r = 0.67–0.77) SLS. Fallers trend (p = 0.054) lower scores on original BESTest, had significantly all versions. Conclusions These findings support mini-BESTest briefBESTest over 50 years old.
