The aim of this study was to develop a questionnaire for measuring depressed patients' knowledge of their disease.
55 patients suffering from depressive episodes answered a 77-items questionnaire.
Item analysis showed a discriminative power higher than 30 for 40 items, all of which applied to one factor. The items were arranged into two thematically similar 20 items forms. We added four additional items (discriminative power between 0.20 and 0.29) because future research may lead to different results concerning discriminative power. The questionnaires DEWIPA-A and DEWIPA-B consists of 24 items each. The average difficulty is equal for both DEWIPA forms and they both possess significant discriminative power.
Our results support the hypothesis that DEWIPA is a valid and reliable instrument to determine patients' knowledge of symptoms, causes and the psychopharmacological treatment of depression.
本研究旨在开发一份用于测量抑郁症患者疾病知识的问卷。
55名患有抑郁发作的患者回答了一份包含77个条目的问卷。
项目分析显示，40个条目的区分度高于30，所有这些条目都适用于一个因素。这些条目被整理成两个主题相似的各含20个条目的形式。我们又增加了4个条目（区分度在0.20至0.29之间），因为未来的研究可能会在区分度方面得出不同结果。DEWIPA - A和DEWIPA - B问卷各由24个条目组成。两种DEWIPA形式的平均难度相同，且都具有显著的区分度。
我们的结果支持以下假设，即DEWIPA是一种有效且可靠的工具，可用于确定患者对抑郁症症状、病因及心理药物治疗的了解程度。
