Social functioning is a primordial aspect of mental health and it should be considered as an important outcome measure in psychiatric treatments and studies. Few short and simple assessment instruments are available in French. Recently, the Questionnaire de Fonctionnement Social (QFS) was developed to study social behavior of psychiatric patients. The QFS is a 16-item self-report questionnaire assessing the frequency of and the satisfaction with social behavior during the last two weeks. The aim of the present study is to explore QFS psychometric properties in a sample of patients with borderline personality disorder.
Eighty-six outpatients (78 women and eight men, mean age: 30.5+/-8.6) with borderline personality disorder and 100 healthy matched control subjects (89 women and 11 men, mean age: 30.2+/-7.7) completed the QFS. The convergent and divergent validities of the QFS were tested with the following instruments: Social Adaptation Self-Evaluation Scale (SASS), Brief Symptom Inventory (BSI), Beck Depression Inventory (BDI), Beck Hopelessness Scale (BHS) and a visual scale of suffering (EVS). Test-retest reliability of the QFS was calculated in a sub-sample of 28 subjects and its sensitivity to change was measured for 45 patients.
Internal consistency of the QFS' global index was satisfying (Cronbach alpha from 0.59 to 0.84). Test-retest reliability of the QFS indexes ranged from 0.77 to 0.79 (intraclass correlation coefficient). Correlations between QFS and SASS demonstrated moderate convergent validity (r>0.59) whilst associations with others psychological measures (BSI, BDI, BHS, EVS) showed satisfying divergent validity (-0.42<r<-0.12). Discriminate validity was excellent as the group of healthy control subjects scored significantly higher than the group of patients in all variables (Mann-Whitney all p<0.001). QFS sensitivity to change after psychotherapeutic treatment was good as shown by the significant change observed in Frequency and Satisfaction index (Wilcoxon respectively p=0.002 and p<0.001).
The QFS demonstrated satisfying psychometric properties in the studied population. This study confirms it is a valuable tool to assess social functioning of borderline personality disorder patients.
社会功能是心理健康的一个基本方面，在精神科治疗和研究中应将其视为一项重要的结果指标。法语版的简短且简单的评估工具很少。最近，社会功能问卷（QFS）被开发出来用于研究精神科患者的社会行为。QFS是一份包含16个条目的自陈式问卷，用于评估过去两周内社会行为的频率及满意度。本研究的目的是在边缘型人格障碍患者样本中探索QFS的心理测量学特性。
86名边缘型人格障碍门诊患者（78名女性和8名男性，平均年龄：30.5±8.6岁）和100名匹配的健康对照者（89名女性和11名男性，平均年龄：30.2±7.7岁）完成了QFS。使用以下工具对QFS的收敛效度和区分效度进行测试：社会适应自我评估量表（SASS）、简明症状量表（BSI）、贝克抑郁量表（BDI）、贝克绝望量表（BHS）以及痛苦视觉量表（EVS）。在28名受试者的子样本中计算QFS的重测信度，并对45名患者测量其对变化的敏感性。
QFS总体指数的内部一致性令人满意（克朗巴哈α系数从0.59至0.84）。QFS各指数的重测信度在0.77至0.79之间（组内相关系数）。QFS与SASS之间的相关性显示出中等程度的收敛效度（r>0.59），而与其他心理测量指标（BSI、BDI、BHS、EVS）的相关性显示出令人满意的区分效度（-0.42<r<-0.12）。区分效度极佳，因为在所有变量上，健康对照组的得分显著高于患者组（曼-惠特尼检验所有p<0.001）。心理治疗后QFS对变化的敏感性良好，频率和满意度指数出现了显著变化（威尔科克森检验分别为p=0.002和p<0.001）。
