The Forensic Restrictiveness Questionnaire (FRQ) is a self-administered questionnaire for forensic mental health inpatients about their subjective experiences of restrictiveness. The present paper describes the validation of the German version of the FRQ.
Patients were recruited from eight forensic psychiatric hospitals in Germany. Internal consistency was explored using Cronbach's α. The German version of the EssenCES (assessing ward climate), the MQPLa (assessing quality of life) and the Mental Health Component subscale of the SF-12 were used to explore convergent validity. The Physical Health Component subscale of the SF-12 was used to explore divergent validity. Patient's levels of leave (Lockerungen), substance use behavior and occurrence of incidents were used to describe criterion validity.
The analysis indicated very good internal consistency according to Cronbach's α. Convergent validity could be confirmed as the FRQ-G mean score was significantly negatively correlated with the EssenCES mean score and the MQPLa mean scores. No sufficient correlation could be shown for the Mental Health Component of the SF-12. A low correlation was found with the physical component of the SF-12, indicating discriminant validity. Very few significant correlations were found to establish criterion validity.
The data indicate the FRQ-G to have good construct validity (structural, convergent, divergent) but failed to fully demonstrate criterion validity. Possible reasons include an underpowered sample size and possible measurement errors. Implications for future research are discussed.
法医限制问卷（FRQ）是一份针对法医精神科住院患者的关于其限制主观体验的自填式问卷。本文描述了FRQ德文版的验证情况。
从德国八家法医精神病医院招募患者。使用克朗巴赫α系数探索内部一致性。使用德文版的埃森病房氛围量表（EssenCES，评估病房氛围）、生活质量问卷（MQPLa，评估生活质量）以及SF-12心理健康分量表来探索收敛效度。使用SF-12身体健康分量表来探索区分效度。患者的请假水平、物质使用行为和事件发生率用于描述效标效度。
分析表明，根据克朗巴赫α系数，内部一致性非常好。由于FRQ-G的平均得分与EssenCES平均得分和MQPLa平均得分显著负相关，因此可以确认收敛效度。对于SF-12的心理健康分量表，未显示出足够的相关性。发现与SF-12的身体分量表相关性较低，表明具有区分效度。发现很少有显著相关性来确立效标效度。
数据表明FRQ-G具有良好的结构效度（结构效度、收敛效度、区分效度），但未能充分证明效标效度。可能的原因包括样本量不足和可能的测量误差。讨论了对未来研究的启示。
