LPFS-BF (Level of Personality Functioning Scale - Brief Form)
ECR-R (Experiences in Close Relationships - Revised)
RSES (Rosenberg Self-Esteem Scale)) one time. Group 2: Group 2 (outpatient group): The outpatients from psychiatric services will complete the same questionnaires as the outpatient clinical group (OPD
BSI (Brief Symptom Inventory)
RSES (Rosenberg Self-Esteem Scale)) one time. Group 3: Group 3 (non-clinical): The non-clinical participants will complete the OPD-SQS (questionnaire on psychic structure or personality functioning) a
