Abstract

OBJECTIVES

Measuring severity of psychopathological symptoms using self-assessment questionnaires is important for clinical and scientific research. However, there is no widely-available Polish tool which measures both overall functioning and severity of a broad spectrum of psychopathological symptoms. This paper describesthe designing of such a tool -the General Functioning Questionnaire (GFQ-58).

METHODS

Three studies were conducted to verify the validity and reliability of the GFQ-58: (1)a study comparing 30 individuals diagnosed with schizophrenia and 30 with no psychiatric diagnosis; (2) a correlational study on 602 individuals exploring relationships between the GFQ-58 and tendency for rumination and quality of life; and (3) a study on 37 patients from a ward which treats neurotic and personality disorders, exploring the relationships between the GFQ-58 and tools for measuring severity of psychopathological symptoms, overall functioning and neurotic personality.

RESULTS

The first study revealed large differences between individuals suffering from schizophrenia and healthy individuals in the overall score of the questionnaire (p < 0.001; d = 1.30) and some of its subscales. The second study showed strong relations between the GFQ-58 and both severity of rumination (p < 0.001; . = 0.64) and quality of life (p < 0.001; .=-0.81). The third study identified relationships between the GFQ-58 and tools measuring various psychopathological symptoms, overall functioning and neurotic personality. These relationships were moderate or strong (all p . 0.001; r =0.43-0.86). Reliability of the overall score was satisfactory in all studies (Cronbach's . = 0.89-0.92).

CONCLUSIONS

The GFQ-58 has satisfactory validity and reliability. It can be used in both scientific and clinical research as a screening tool for measuring overall functioning and severity of psychopathological symptoms.

摘要

目的

使用自我评估问卷衡量精神病理学症状的严重程度对临床和科学研究很重要。然而，目前还没有广泛使用的波兰语工具可以同时衡量广泛的精神病理学症状的整体功能和严重程度。本文描述了这样一种工具的设计——一般功能问卷（GFQ-58）。

方法

进行了三项研究来验证 GFQ-58 的有效性和可靠性：（1）一项比较 30 名精神分裂症患者和 30 名无精神诊断个体的研究；（2）一项对 602 名个体进行的相关性研究，探讨 GFQ-58 与沉思倾向和生活质量之间的关系；（3）一项对神经症和人格障碍病房 37 名患者的研究，探讨 GFQ-58 与衡量精神病理学症状严重程度、整体功能和神经质人格的工具之间的关系。

结果

第一项研究显示，精神分裂症患者和健康个体在问卷总分（p<0.001；d=1.30）和一些子量表上存在显著差异。第二项研究表明，GFQ-58 与沉思严重程度（p<0.001；.=0.64）和生活质量（p<0.001；.=-0.81）之间存在很强的关系。第三项研究确定了 GFQ-58 与衡量各种精神病理学症状、整体功能和神经质人格的工具之间的关系。这些关系是中度或高度相关（所有 p<0.001；r=0.43-0.86）。在所有研究中，总体得分的可靠性均令人满意（Cronbach's.=0.89-0.92）。
