Abstract

Receiving support may yield negative outcomes, although these can be offset by reciprocating support. Here, we argue that support receipt and reciprocation should be considered with reference to two separate needs, for relatedness/communion and competence/agency, which underlie differential effects of equity on affective versus relational outcomes. To test these, we go beyond earlier studies by (a) examining equity along a (daily) continuum, (b) using the novel analytic approach of polynomial regression with response surface analyses, and (c) indexing equity from both monadic and dyadic perspectives. Using dyadic daily diaries (NDays = 35, NCouples = 80), we found personal outcomes (positive affect [PA] and negative affect [NA]) to be worst on inequitable days, particularly overbenefit ones. In contrast, equity did not play the same role with regard to relational outcomes (closeness/satisfaction), for which overbenefit proved more positive. Interestingly, the monadic and dyadic perspectives converged more with personal than with relational outcomes.
