Daily receiving and providing of social support at work: identifying support exchange patterns in hierarchical data

The norm of reciprocity proposes that one who receives support feels obliged to return obtained benefits. Yet how employees regulate the mutual flow of social support with one another does not always follow a reciprocal dynamic, which may have different implications for employee outcomes based on whether social exchanges gain, drain or conserve resources. To better understand support exchange patterns and their relationship with basic need satisfaction (for autonomy, competence and relatedness) and emotional exhaustion in employees' daily lives, we performed a multilevel latent profile analysis (N = 124 employees, 894 days). At the day level, we identified four support exchange profiles differing in low vs high received and provided social support (i.e., low-reciprocating, under-reciprocating, over-reciprocating and high-reciprocating days). At the person level, we identified three support exchange classes of employees, differing in the degree to which employees showed certain support exchange profiles over time (i.e., over-reciprocators, low-reciprocators and high-reciprocators). Pairwise comparisons with multinomial logistic regression revealed that over-reciprocating days were associated with the highest levels of need satisfaction for autonomy and relatedness and the lowest levels of emotional exhaustion. Moreover, over-reciprocators were most likely to satisfy their needs for autonomy. We discuss theoretical and practical contributions of our findings.
