HUBUNGAN ANTARA KELEKATAN TIDAK AMAN DAN HARGA DIRI DENGAN PERILAKU PEOPLE PLEASING PADA USIA DEWASA AWALNIM.: 22107010055Sastya Putri Al HasniauthorEarly adulthood is a phase of emerging adulthood characterized by identity exploration, emotional instability, and the need for social acceptance. This condition can encourage individuals to excessively adjust themselves and avoid conflict, thereby giving rise to people-pleasing behavior, which is the tendency to prioritize others’ needs in order to gain approval and avoid rejection. This behavior is influenced by several factors, including Kelekatan tidak aman and harga diri, where Kelekatan tidak aman is associated with fear of rejection and conflict in interpersonal relationships that stems from Kelekatan tidak amanexperiences in childhood, while low harga diri increases dependence on others’ acceptance. This study aims to examine the relationship between Kelekatan tidak aman and harga diri with people-pleasing behavior in early adulthood. This study used a quantitative approach with a correlational design. The research subjects consisted of 200 respondents with the characteristics of individuals aged 18-30 years who reside in the Special Region of Yogyakarta. The sampling technique used was convenience sampling. Data collection was conducted online using Google Forms with three psychological scales, namely a people-pleasing scale translated into Indonesian based on the concept of Braiker (2001), an Kelekatan tidak aman scale using the Inventory of Parent and Peer Attachment (IPPA) modified version by the researcher, and a harga diri scale using The Coopersmith Harga diri Inventory (CSEI) modified version by the researcher. Data analysis used multiple regression techniques. The results of the study indicate that the major hypothesis is accepted, meaning that there is a significant relationship between Kelekatan tidak aman and harga diri with people-pleasing behavior. However, partially (minor hypotheses), Kelekatan tidak aman does not have a significant relationship with people-pleasing, while harga diri has a negative and significant relationship with people-pleasing.150 Psikologi2026-05-06UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU SOSIAL DAN HUMANIORAThesis
