Abstract

The objectives were to translate the University of Jyvaskyla Active Aging Scale (UJACAS) to Swedish, to establish semantic equivalence and evaluate psychometric properties for use among persons 55 years and older in Sweden. The UJACAS contains 17 items to be self-assessed regarding goals, abilities, opportunity, and activity. Psychometric properties content validity, data quality including floor and ceiling effects, test-retest reliability, internal consistency, and construct validity were evaluated with different samples in three phases, using state-of-the-art statistics. After translating and establishing semantic equivalence, content validity was assessed as high. With ICC = 0.88 (95% CI 0.80–0.93) test-retest reliability was moderate. Internal consistency was high (Cronbach alpha = 0.84–0.91), and 84% of the questions reached the cut-off value of 0.3 for corrected item-total correlation. Construct validity hypotheses were confirmed. Results indicate that the UJACAS is reliable and valid for use among persons 55 and older in Sweden.
