The influence of husband and wife personality on marital social support interactions

The influence of extraversion and negative affectivity on support interactions among married couples was examined. One hundred married couples were observed in two 10-minute interactions that were designed to elicit supportive behaviors. Extraverted support providers gave more support to their spouse than did introverts. Reciprocity in the exchange of support behaviors was also observed: The amount of support given by the individual in the first interaction predicted the amount of support provided to him or her during the second interaction. Negative affectivity was negatively correlated with ratings of interaction supportiveness, even when controlling for the number of supportive and negative behaviors received from the spouse. Extraverts showed higher sensitivity to emotional support behaviors than did introverts. The same level of emotional support behaviors from the spouse led to higher ratings of interaction supportiveness among those high on extraversion than among those low on extraversion. Results highlight the importance of integrative models of support that consider characteristics of the individual and his or her social environment.
