Note. Table entries for b are unstandardized regression coefficients. All non-dichotomous variables were centered at the total sample mean. CR = care recipient. IADL = Instrumental Activities of Daily Living. ADL = Activities of Daily Living. The overall F value for Model 1 = 3.30 (p = .003). The overall F value for Model 2 = 3.18 (p = .005). For the variables included in interaction terms with Gender (CR number of IADLs, CR number of health conditions, Couple’s number of proximate daughters, and Spouse’s age – CR’s age) the interpretation of the b coefficients differ for Model 1 and Model 2 (Jaccard, 2001). In Model 1, b represents the slope of each of these variables on the likelihood of solo spousal caregiving for all couples. In Model 2 b represents the slope of the relationship between each of these variables and the likelihood of solo spousal caregiving among couples for whom gender was coded 0, i.e., couples in which the husband was the CR.
0 = No, 1 = Yes.
0 = Non-Hispanic White, 1 = Non-Hispanic Black/African American.
0 = CR husband, 1 = CR wife.
