Compassion is the capacity for being moved by the suffering of others and wanting to help alleviate it. Compassion may mediate the health benefits and hazards of social networks and relationships. The monitoring and management of the level of compassion across social networks and relationships may be critical to the preservation of the health benefits and the prevention of the health hazards of social networks and relationships. We developed a 10-item self-report measure of compassion and evaluated its psychometric properties among 310 respondents drawn from the University and its surrounding communities. The mean total score was 3.62 (SD=1.09). The item-to-total correlations ranged from 0.50-0.71. The mean inter-item correlation was 0.33. The internal consistency was 0.82. The scale correlated well with the Sprecher and Fehr's Compassionate Love Scale (r=0.66; p=.000). Two method factors measuring the same construct explained 57% of the variance in the sample. The scale is user-friendly, easy to score, and characterized by good psychometric properties. It can be used to foster the understanding of the impact of the level of compassion on disease occurrence and outcomes across social networks and relationships.
