Psychometric validation of the Chinese version of the PaArticular Scales
among elderly residents in long-term care facilities with joint
contractures
Abstract
Rationale, aims and objectives: Joint contractures are common
complications among elderly residents in long-term care facilities,
causing activity limitations and participation restrictions and
affecting quality of life (QOL). The aim of this study is to examine the
psychometric properties of the Chinese version of the PaArticular Scales
in joint contractures population. Methods: A cross-sectional study
design. A sample of elderly residents aged over 64 years with joint
contractures in one important joint who have lived at a facility for
more than 6 months in twelve long-term care facilities in Taiwan (n =
243). The Chinese version of the PaArticular Scales of joint
contractures was generated through 5 stages: translation, review,
back-translation, a panel of specialists, and a pretest. Test-retest
reliability, internal consistency reliability, construct validity, and
criterion validity were evaluated, and the results were compared with
those for the WHOQOL-BREF and WHODAS 2.0-36 items. Criterion validity
was assessed using correlation coefficients to examine changes in the
activity limitations and participation restrictions subdomain and
predict QOL. Results: The Activities and Participation subscales had
excellent internal consistency (Cronbach’s α coefficient = .975; SD =
17.34). The correlation coefficients between the PaArticular Scales and
the WHODAS 2.0-36 items (r = .770, p < .001) and WHOQOL-BREF
were significant and highly correlated (r = -.553, p < .001).
Conclusions: The underlying theoretical model of the Chinese version of
the PaArticular Scales functions well in Taiwan, and the Chinese version
has acceptable levels of reliability and validity.
