This study focuses on the psychometric characteristics of a self-report instrument, the Delusion and Voices Self-Assessment (DV-SA) questionnaire, to assess delusions and auditory hallucinations from the clients' perspective.
The DV-SA was administered to 70 schizophrenic patients in treatment in an outpatient mental health clinic in Naples, Italy. It was administered twice to determine the test-retest reliability. A clinician who was blind to the patients' DV-SA ratings also rated the Brief Psychiatric Rating Scale (BPRS). Sensitivity to change was assessed in 30 patients who completed a 24-week course of cognitive-behavioural therapy sessions.
The DV-SA showed good internal consistency and structure, and an acceptable average of item-total correlation. The test-retest reliability was very satisfactory. The comparison between DV-SA and BPRS showed a good association for illness severity.
The DV-SA may be a reliable, valid and sensitive instrument for assessing subjective experiences on delusions and auditory hallucinations. The brevity and limited need for assistance make it an efficient instrument to assess patients' evolution during therapy.
本研究聚焦于一种自我报告工具——妄想与幻听自我评估（DV-SA）问卷的心理测量特性，旨在从患者角度评估妄想和幻听。
DV-SA问卷被发放给意大利那不勒斯一家门诊心理健康诊所正在接受治疗的70名精神分裂症患者。问卷发放了两次以确定重测信度。一名对患者的DV-SA评分不知情的临床医生同时对简明精神病评定量表（BPRS）进行评分。对30名完成了为期24周认知行为治疗课程的患者评估了变化敏感性。
DV-SA显示出良好的内部一致性和结构，以及可接受的项目总分相关性平均值。重测信度非常令人满意。DV-SA与BPRS之间的比较显示出在疾病严重程度方面有良好的相关性。
DV-SA可能是一种用于评估妄想和幻听主观体验的可靠、有效且敏感的工具。其简短性以及对协助的有限需求使其成为评估患者治疗期间进展情况的有效工具。
