Sintesi	The Suicide Probability Scale (SPS) is a 36-item self-report instrument developed by John Cull and William Gill (1990) to assess suicide risk, hopelessness, suicide ideation, negative self-evaluation, and hostility in adolescents and adults. It provides a multidimensional profile of suicide-related cognitions and emotions and is used in clinical, psychiatric, school, and forensic settings to screen for suicide risk and guide treatment planning.	The Novaco Anger Scale and Provocation Inventory (NAS-PI) is a comprehensive self-report assessment instrument developed by Raymond Novaco (2003) to measure dispositional anger and anger provocation in adolescents and adults. It integrates cognitive-behavioral theory of anger and emotional regulation, serving clinicians, forensic practitioners, and researchers in psychiatric, correctional, and clinical settings where anger dysregulation and aggression risk are clinical concerns.
