The Self-Report Symptom Inventory (SRSI) is a novel tool designed to detect symptom overreporting and other forms of noncredible responding. Unlike existing scales, the SRSI includes genuine and pseudosymptoms scales covering cognitive, affective, motor, pain, and post-traumatic stress disorder domains. The present study aims to investigate the psychometric properties of the Italian Version of the SRSI (SRSI-It), in particular, its factor structure, reliability, convergent and discriminant validity, and diagnostic accuracy. Data from 1180 healthy participants showed a hierarchical structure with higher-order constructs for genuine symptoms and pseudosymptoms, each comprising five subscales. The SRSI-It showed a strong convergent validity with the Structured Inventory of Malingered Symptomatology and discriminant validity through low correlations with the Psychopathic Personality Inventory-Revised. Receiver operating characteristic analysis determined cut scores of 6 (95% specificity) and 9 (98% specificity) for pseudosymptoms, with a Ratio Index score of 0.289 (82% specificity). In summary, the SRSI-It appears to be a promising tool for identifying symptom exaggeration in clinical and forensic contexts, ultimately enhancing the quality and reliability of evaluations in these contexts.
自我报告症状量表（SRSI）是一种旨在检测症状过度报告和其他形式不可信反应的新型工具。与现有量表不同，SRSI包括涵盖认知、情感、运动、疼痛和创伤后应激障碍领域的真实症状量表和伪症状量表。本研究旨在调查意大利版SRSI（SRSI-It）的心理测量特性，特别是其因子结构、信度、收敛效度和区分效度以及诊断准确性。来自1180名健康参与者的数据显示出一种层次结构，其中真实症状和伪症状具有高阶结构，每个结构包含五个子量表。SRSI-It与伪装症状结构化量表显示出很强的收敛效度，并且通过与修订后的精神病态人格量表的低相关性显示出区分效度。接受者操作特征分析确定伪症状的临界分数为6（特异性95%）和9（特异性98%），比率指数分数为0.289（特异性82%）。总之，SRSI-It似乎是一种很有前景的工具，可用于在临床和法医环境中识别症状夸大，最终提高这些环境中评估的质量和可靠性。
