Friendship Quality Questionnaire

The Friendship Quality Questionnaire is a self-report instrument designed to assess the quality and characteristics of friendships in children, adolescents, and adults. Developed by Jeffrey Parker and Steven Asher in 1993 and expanded by Bukowski and colleagues, the FQQ measures dimensions of friendship quality including companionship (spending time together), conflict, help and guidance, intimate disclosure, closeness, loyalty, and conflict resolution. The FQQ is widely used in developmental psychology, peer relationship research, and clinical assessment of social functioning across the lifespan.
