Abstract

Background and objectives

The Functioning Assessment Short Test (FAST) is widely used to assess psychosocial functioning across psychiatric conditions. Despite extensive international validation, a validated French version of the self-administered FAST is currently lacking. This study aimed to evaluate the psychometric properties of the self-administered French FAST in a general adult population.

Methods

A total of 508 French-speaking adults aged 18–65 completed the FAST alongside standardized measures of depression and anxiety. Exploratory and confirmatory factor analyses and bifactor modeling evaluated the original six-factor structure. Reliability was assessed using Cronbach’s alpha and McDonald’s omega. Convergent validity was evaluated through multitrait-multimethod (MTMM) analysis and correlations with depression and anxiety. Generalized additive models (GAMs) examined non-linear associations between symptom severity and FAST scores, controlling for demographic covariates.

Results

The original six-factor structure was confirmed, and the bifactor model further supported interpretation of both total and subscale scores. Reliability was strong for the total FAST score (α = .86; ω = .90), whereas subscale reliability (α = .58–.80), with lower values for autonomy, cognitive, and leisure. MTMM analysis demonstrated moderate-to-high monotrait correlations (.51–.84), and moderate correlations with depressive (r = .46) and anxiety (r = .35) symptoms, supporting convergent validity. GAM analyses revealed a non-linear relationship between depressive symptoms and psychosocial impairment (edf = 2.91, F = 19.87, p < .001), alongside significant effects of anxiety (p = .024) and employment status (p = .003).

Conclusions

The French self-administered FAST demonstrates robust psychometric properties and appears suitable for assessing psychosocial functioning in general adult populations, though caution is advised when interpreting autonomy, cognitive, and leisure subscales in non-clinical samples until further clinical validation is available.

自我管理法语版功能评估短测验（FAST）的心理计量学验证：因素结构、信度、效度和社会人口预测因子

背景和目的功能评估短测试（FAST）被广泛用于评估精神疾病的社会心理功能。尽管得到了广泛的国际认可，但目前还缺乏经过验证的法语版自我管理FAST。本研究旨在评估一般成年人自我管理的法语FAST的心理测量特性。方法共有508名年龄在18-65岁的法语成年人完成了FAST，并进行了标准化的抑郁和焦虑测量。探索性和验证性因子分析和双因子模型评估了原来的六因子结构。采用Cronbach 's alpha和McDonald 's omega评估信度。通过多特质-多方法（MTMM）分析评估收敛效度，并与抑郁和焦虑进行相关性分析。广义加性模型（GAMs）检验了症状严重程度和FAST评分之间的非线性关联，控制了人口统计学协变量。结果原来的六因子结构得到证实，双因子模型进一步支持总分和分量表得分的解释。FAST总分的信度较高（α = 0.86; ω = 0.90），而次量表的信度较高（α = 0.58 - 0.90）。80)，自主性、认知和休闲的价值较低。MTMM分析显示了中至高的单性状相关性（0.51 -）。84)，并且与抑郁（r = 0.46）和焦虑（r = 0.35）症状有中度相关性，支持收敛效度。GAM分析显示，抑郁症状与心理社会障碍之间存在非线性关系（edf = 2.91, F = 19.87, p < .001），焦虑（p = 0.024）和就业状况（p = 0.003）也有显著影响。结论：法国自我管理的FAST显示出强大的心理测量特性，似乎适用于评估一般成年人的社会心理功能，尽管在解释非临床样本的自主性、认知和休闲亚量表时建议谨慎，直到进一步的临床验证可用。

期刊介绍： The European journal of psychiatry is a quarterly publication founded in 1986 and directed by Professor Seva until his death in 2004. It was originally intended to report “the scientific activity of European psychiatrists” and “to bring about a greater degree of communication” among them. However, “since scientific knowledge has no geographical or cultural boundaries, is open to contributions from all over the world”. These principles are maintained in the new stage of the journal, now expanded with the help of an American editor.
