The purpose of the present study was to examine the relationship between different levels of cognitive, emotional, and spiritual development with adult psychological well-being. A sample consisted of 700 adults in ages between (20-60) was selected using a convenience sampling method. Questionnaires consisted of Social Paradigm Belief Inventory (SPBI), Spiritual Well-Being (SHALOM), Interpersonal Reactivity Index (IRI), Spiritual Assessment Inventory (SAI), BUSS & Perry Aggression Questionnaire – Short form (BPAQ – SF), Connor-Davidson Resilience Scale– Short form (CD-RISC-SF), Maladaptive Hedonism Questionnaire, Difficulties in Emotion Regulation Scale (DERS), Psychopathic Personality Inventory-Revised(PPIR), Gratitude Questionnaire (GQ-6), Altruistic Behavior Questionnaire, Symptom Checklist-90-Revised (SCL-90-R), and Depression, Anxiety and Stress Scale (DASS-21). Research data were analyzed using structural equation modeling. The findings showed that relativistic thought affects stress, empathy, and difficulties in emotion regulation. Dialectical thought has a positive effect on empathy and spiritual well-being. Egocentrism has a positive effect on difficulties in emotion regulation and spiritual weakness and a negative effect on Spiritual well-being. Stress has a positive effect on difficulties in emotion regulation. Difficulties in emotion regulation positively affect spiritual weakness and negatively affect Spiritual well-being. Also, Empathy has a positive effect on spiritual wellbeing. Spiritual weakness positively affects aggression, depression, and maladaptive hedonism. But, it negatively affects altruism. Spiritual well-being negatively affects depression and maladaptive hedonism and positively affects resilience, altruism, and gratitude.
