概要	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.	The Attachment Style Questionnaire is a self-report instrument measuring adult romantic attachment patterns based on attachment theory. Developed following Hazan and Shaver's seminal 1987 work extending John Bowlby's attachment theory to adult romantic relationships, the ASQ assesses individual differences in attachment anxiety (fear of abandonment and desire for closeness) and attachment avoidance (discomfort with intimacy and emotional dependence). The ASQ is used extensively in relationship research, couple therapy, and studies examining how childhood attachment experiences predict adult romantic functioning.
