THE ASSESSMENT OF POSITIVITY AND NEGATIVITY IN SOCIAL NETWORKS: THE RELIABILITY AND VALIDITY OF THE SOCIAL RELATIONSHIPS INDEX

摘要

The Social Relationships Index (SRI) was designed to examine positivity and negativity in social relationships. Unique features of this scale include its brevity and the ability to examine relationship positivity and negativity at the level of the specific individual and social network. The SRI’s psychometric properties were examined in three studies. The SRI demonstrated good psychometric properties, including test–retest reliability for the assessment of positivity and negativity, and of relationship classifications across social networks. Additionally, discriminant and convergent validity was established with existing social relationship and personality scales. Finally, the SRI showed some generalizability across different contexts. These studies suggest that the SRI is a reliable and valid alternative measure for use in health studies that require a shorter assessment of relationships.
