Thus, studying self-compassion with a multidimensional approach provides valuable insight. The aim of this study is to investigate the predictor role of behavioral inhibition/activation system and mother acceptance-rejection level (as an early life experience) on self-compassion. Method: The sample of the study consists of 301 participants; 192 female (63.8%) and 109 male (36.2%). The mean age of the sample is 24.56 (SD?=?5.95). Socio-demographic form, Self-Compassion Scale-Short Form, Behavioral Inhibition System/Behavioral Activation System Scales (BIS/BAS scale) and Parental Acceptance-Rejection Questionnaire (mother form) were conducted. Results: The results of the hierarchical regression analysis revealed that in the first step BIS negatively predicted self-compassion (R2?=?.27, p?<?.01). When mother hostility/aggression was added (2.step), it also predicted self-compassion negatively and made a small change in the explained variance (R2 change = .01, p?<?.05). Thus, BIS is a stronger predictor than mother hostility/aggression for self-compassion. Conclusions: Consequently, BIS and mother hostility/aggression both predict self-compassion. To our knowledge this is the first empirical study that investigated self-compassion with the role of biological systems and early childhood experiences together. These findings provide valuable knowledge to consider motivational systems (BIS/BAS) in the self-compassion interventions.eninfo:eu-repo/semantics/openAccessConference Object581818818Q1WOS:00114461000549010.1002/ijop.13054
