Empathy involves understanding and sharing another person's emotional state or experience. It has advantages like improved relationships and performance, but can also make one feel uncomfortable. When providing social support, one should focus on the other person rather than oneself. Visible support that undermines the recipient's self-efficacy can be unhelpful, while invisible support maintaining both parties' efficacy is most supportive. The most distressing type of support is visible support that implies recipient inefficacy, while invisible mutual-efficacy support is generally seen as most supportive.
