Development and psychometric evaluation of the Caregiver Reciprocity Scale II.
Caregiver reciprocity is the collective affective and behavioral expression of exchanges given and received between a caregiver and care receiver, and among family members. This psychometric investigation was designed to further examine the reliability and validity of the revised Caregiver Reciprocity Scale II (CRS II). Items were rewritten to reflect valued exchanges and balance among the entire family network, including spouses. An alpha of .83 for Warmth and Regard; .73 for Intrinsic Rewards of Giving; .83 for Love and Affection; and .75 for Balance Within Family Caregiving indicated acceptable internal consistency. The study, conducted with 176 spouse or adult children caregivers, provides additional support for the conceptual model of the four-factor solution. Construct validity was supported by the standardized factor loadings and goodness-of-fit indices obtained from confirmatory factor analysis. The results of the analysis of the measurement model, taken as a whole, demonstrate that the CRS II has adequate psychometric properties. Model parsimony was supported by an AGFI of .87, combined with an adjusted chi-square between 1.0 to 3.0. All but two item loadings were greater than .50. This, combined with the fact that all standardized loadings were twice the standardized errors and t-values were greater than 2.0, contributes to concluding that convergent validity was strong. Discriminant validity, evaluated by variance extracted estimates, and confidence interval (+/- two standard errors) around the correlation estimate between factors, was adequate. This study provided evidence to support the reliability and validity of the CRS II.
