Inventory of Altered Self-Capacities (IASC)

The IASC is a self-report questionnaire designed to explore difficulties related to emotional regulation, identity, interpersonal relationships, and certain coping patterns frequently associated with psychological trauma, particularly developmental trauma and complex trauma. It helps the psychologist objectify alterations in self-functioning that are not always captured by scales focused solely on anxiety, depression, or posttraumatic stress disorder. The tool is particularly useful in the clinical assessment of adults with a history of abuse, neglect, repeated victimization, or marked disturbances of attachment and emotional stability. Its interpretation is based on a profile of subdimensions rather than a single categorical diagnosis, which makes it a relevant instrument for screening, case formulation, and therapeutic follow-up.
