Psychometric properties of the KPAS in diverse ethnic groups of midlife women.

The Kaiser Physical Activity Survey (KPAS), designed specifically for diverse activity domains (housework, caregiving, occupational activity), is used to assess physical activity among multiethnic midlife women. This study evaluates KPAS reliability and validity (not widely documented) in measuring physical activity among 341 groups in this classification. Internal consistency coefficients are adequate for all ethnic groups except non-Hispanic (N-H) African Americans. To evaluate construct validity, the researchers use multiple analytic approaches, including correlation between behavioral intention and KPAS scores and factor analysis. KPAS scores correlate positively with behavioral intention scores among all ethnic groups. Eight factors are extracted among all groups except N-H Asian Americans. In the convergent validity test, N-H African Americans and N-H Asian Americans show unique patterns. Overall, the KPAS proves reliable as a reasonably accurate instrument to assess physical activities among multiethnic groups of midlife women. However, cultural sensitivity among N-H African Americans and N-H Asian Americans needs further examination.
