Does Gender Moderate Factors Associated With Whether Spouses Are the Sole Providers of IADL Care to Their Partners?

The authors explored whether gender moderated the influence of other factors on solo spousal caregiving. The subsample (n = 452) from the Asset and Health Dynamics Among the Oldest Old study included elderly care recipients (CRs) receiving assistance with instrumental activities of daily living (IADLs) and their spouses. Logistic regression was used to model the likelihood of solo spousal IADL care. Gender moderation was tested by product terms between CRs' gender and measures of partners' health, potential helpers, and sociodemographic characteristics. As numbers of CRs' IADLs and couples' proximate daughters increased, wives less often received care solely from their husbands, but husbands' receipt of care from their wives was unaffected. Age differences between spouses and CRs affected solo spousal caregiving to wives and husbands in opposite ways. Regardless of gender, CRs' numbers of limitations in activities of daily living and spouses with limitations in IADLs or activities of daily living reduced the likelihood of solo spouse care. Identifying circumstances influencing solo spouse caregiving differently among couples with frail wives and husbands facilitates gender-sensitive services.
