This study examined the psychometric properties of the Family Questionnaire (FQ): a self-report measure of relatives' perceptions of the behaviours and symptoms of schizophrenic patients in terms of three dimensions: the frequency of symptoms, the relatives' concern (primary appraisal) and their ability to cope (secondary appraisal) with the symptoms.
Factor analysis of the FQ, test-retest and inter-rater reliability, and measures of validity were examined.
Factor analysis supported the validity of five subscales labelled negative symptoms, antisocial behaviours, interpersonal problems, affective symptoms and psychotic symptoms. Test-retest reliability for all scales was good and the prediction that there would be limited correspondence between two different relatives' scores was supported for the subscales of negative symptoms and affective symptoms. Concurrent measures of relatives' distress, burden and patients' symptomatology indicated that the FQ showed acceptable validity. In particular, the study showed that high expressed emotion relatives have higher scores on the appraisal dimensions of some subscales.
The study provides evidence that the FQ is a useful tool for measuring relatives' perceptions of schizophrenic illness, particularly within the context of family interventions where it may be utilized to help to understand the factors mediating relatives' burden and distress.
本研究检验了家庭问卷（FQ）的心理测量特性，这是一种自我报告测量工具，用于从三个维度衡量亲属对精神分裂症患者行为和症状的看法：症状频率、亲属的担忧（初级评估）以及他们应对症状的能力（次级评估）。
对FQ进行了因素分析、重测信度和评分者间信度检验以及效度测量。
因素分析支持了五个分量表的效度，分别标记为阴性症状、反社会行为、人际问题、情感症状和精神病性症状。所有量表的重测信度良好，阴性症状和情感症状分量表支持了不同亲属得分之间相关性有限这一预测。亲属痛苦、负担以及患者症状的同时测量表明，FQ显示出可接受的效度。特别是，研究表明高情感表达亲属在某些分量表的评估维度上得分更高。
该研究提供了证据，证明FQ是衡量亲属对精神分裂症疾病看法的有用工具，尤其是在家庭干预的背景下，它可用于帮助理解介导亲属负担和痛苦的因素。
