: The assessment of dangerousness and risk of recidivism are crucial aspects of forensic psychiatric evaluations, influencing therapeutic and security measures. This study aimed to develop and validate a new tool, the Dangerousness Index in Forensic Psychiatry (IPPML), following a psychometric scale construction methodology. The sample consisted of 261 participants (157 males, 104 females) aged 19-75 years, divided into an experimental group ( = 126) with a history of forensic psychiatric examination and a control group ( 135) diagnosed with schizophrenia. : Exploratory factor analysis revealed two factors, Performance and Social, explaining 45.55% of the data variance. The IPPML demonstrated adequate internal consistency (α = 0.881) for the entire sample, with Factor 1 showing strong consistency (α = 0.896) and Factor 2 exhibiting acceptable consistency (α = 0.628). Reliability ranged from 89.6% to 62.8% when administered to participants with psychoses undergoing forensic psychiatric evaluation, decreasing to 42.5% for legally evaluated patients and increasing from 58.7% to 84.3% for participants with schizophrenia without forensic psychiatric evaluation. Discriminant validity analysis indicated higher psychiatric dangerousness with forensic implications in males. : The IPPML shows promise as a tool for assessing dangerousness in forensic psychiatry and aiding medical decision-making regarding the risk of antisocial and potentially harmful acts.
危险性评估和再犯风险评估是法医精神病学评估的关键方面，会影响治疗和安全措施。本研究旨在遵循心理测量量表构建方法，开发并验证一种新工具——法医精神病学危险性指数（IPPML）。样本包括261名年龄在19至75岁之间的参与者（157名男性，104名女性），分为有法医精神病学检查史的实验组（n = 126）和被诊断为精神分裂症的对照组（n = 135）。探索性因素分析揭示了两个因素，即表现因素和社会因素，解释了45.55%的数据方差。IPPML在整个样本中显示出足够的内部一致性（α = 0.881），其中因素1显示出很强的一致性（α = 0.896），因素2表现出可接受的一致性（α = 0.628）。在对接受法医精神病学评估的精神病患者进行测试时，信度范围为89.6%至62.8%，在接受法律评估的患者中降至42.5%，在未接受法医精神病学评估的精神分裂症患者中从58.7%升至84.3%。判别效度分析表明，男性在法医方面的精神病危险性更高。IPPML有望成为评估法医精神病学中危险性的工具，并有助于就反社会和潜在有害行为的风险做出医疗决策。
