 Objectives : To examine psychometric properties of a newly developed measurement to assess perceived influence on life through family caregiving, consisting of eight items with a 4-point Likert scale, constructed by means of a qualitative research on family caregivers and some comprehensive measures for caregivers' cognitive appraisal.

 Design and Participants : Based on cross-sectional questionnaire survey, response data were obtained anonymously from 1,020 primary caregivers, and 980 without missing the information on gender of age of primary caregivers(757 women and 223 men)were analyzed.

 Results : After checking the response frequencies, a confirmatory factor analysis revealed the two higher-order components, such as “negative influence on life(NEG)” and “positive influence on life(POS)” through family caregiving, with each two underlying(first-order)components, i.e., “social dysfunctioning” and “self-sacrifice” under the NEG, and “positive feeling” and “self- & family growth” under the POS, respectively. The internal consistency reliabilities of all but one scale/subscales were at a satisfactory level. Multi-sample test confirmed the measuring equivalence of this scale between men and women. Structural equation modeling(SEM)analysis indicated the convergent and discriminant validity of the four subscales against caregivers' cognitive appraisal and coping strategies. Furthermore, SEM suggested that “social dysfunctioning” and “positive feeling” might be significant precursors to “self-sacrifice” and “self- & family growth,” respectively.

 Conclusion : These findings suggests that this measurement is a convenient but psychometrically-sound tool to capture the caregiver's perception of positive and negative influences on life through family caregiving.
