Background: The Pervasiveness and Impact of Self-Criticism

 

Self-criticism is a common human experience, characterized by a harsh, judgmental stance toward oneself. While a degree of self-reflection can be adaptive, chronic and excessive self-criticism is widely recognized in psychological literature as a significant contributor to various forms of psychological distress and impairment. It involves evaluating one's thoughts, feelings, and behaviors negatively, often accompanied by feelings of shame, guilt, and worthlessness . This internal dialogue can become a pervasive pattern, impacting emotional regulation, interpersonal relationships, and overall functioning (Nicola Petrocchi et al., 2019). Research consistently links high levels of self-criticism to increased vulnerability to conditions such as depression, anxiety, eating disorders, and personality disorders (Iona Naismith et al., 2019) (Nicola Petrocchi et al., 2019) (Montero-Marín et al., 2016). The physiological correlates of self-criticism often involve activation of the threat system, including amygdala hyperactivity and HPA-axis activation, leading to the secretion of stress hormones like cortisol (Iona Naismith et al., 2019). This physiological response underscores the profound biological impact of a critical inner voice.
