Social Comparison Theory

출력 (발췌)

H1: Adolescents who spend more daily time on image-focused social media will report lower body-image satisfaction than those who spend less time.
H2: The negative relationship between image-focused social media use and body-image satisfaction will be stronger for adolescents with lower baseline self-esteem.
H3: Following appearance-focused accounts will predict greater upward social comparison, which in turn predicts lower body-image satisfaction.

Each is grounded in Social Comparison Theory's premise that exposure to idealized images drives unfavorable self-evaluation.

H1: There is a significant difference in weekly billable output between employees on a four-day work week and those on a five-day week.
H2: Work-week structure is significantly associated with reported employee engagement.
