Interpersonal Emotion Regulation as a Transdiagnostic Target in Adult Psychopathology
Interpersonal Emotion Regulation as a Transdiagnostic Target in Adult Psychopathology

Summary/Abstract: This review study comparatively examines three fundamental theoretical approaches attachment theory, social exchange theory, and the investment model in explaining the phenomenon of loyalty in close relationships. Loyalty is conceptualized as a multidimensional value encompassing trust, commitment, and continuity, and the psychological and behavioral processes associated with this value are evaluated within the framework of these theories. Attachment theory emphasizes the influence of individuals’ early attachment patterns on adult relationship satisfaction and tendencies toward loyalty. Social exchange theory argues that individuals make rational decisions in relationships based on a reward–costbalance, explaining loyalty through the evaluation of benefits and alternatives. The investment model conceptualizes loyalty as a commitment dynamic shaped by the interaction of relationship satisfaction, the quality of alternatives, and the magnitude of investments made in the relationship. The study also evaluates the effects of digitalization and changing social structures on these theoretical approaches. Findings from recent research indicate the effects of social media use, digital privacy, online jealousy, and dating applications on loyalty. The contributions of all three theories to explaining loyalty are comparatively analyzed, revealing the psychological depth of attachment theory, the rational structure of social exchange theory, and the investment model’s emphasis on relational sustainability.
