When employing adaptive behaviors to a changing environment, ability and motivation work hand in hand. Our goal was to investigate how ability and motivation interact when utilizing Facebook for social support and friendship. We predicted that well-being and perceived social support would be negatively related to motivation to use Facebook for social support and friendship. We also predicted that computer-mediated communication (CMC) competence would positively related to these motives. A survey of 282 college students tested our mediational model. Results indicated that perceived social support mediated the relationship between well-being and motivations to use Facebook for social support, but only when CMC competence was high, meaning students experienced this relationship only when both motivated and able to use Facebook for the purpose of seeking social support. The results suggest that interventions to increase CMC competence through Facebook use can help students garner greater social support and improve overall well-being.
