The purpose of the present study was to develop and validate a brief screening instrument (F-SozU K-3) for the measurement of perceived social support in large scale surveys by shortening a well-established German questionnaire (F-SozU K-6).
First, a brief three-item version of the F-SozU was developed based on a representative sample of = 2482 respondents using exploratory and confirmatory factor analysis. Second, the newly developed brief three-item questionnaire was evaluated and standardized in an independent second representative population sample ( = 2501).
A suitable three-item solution with a good internal consistency (α = 0.89, ω = 0.89) was identified. Full invariance across sex and partnership was established. Construct validity of the brief three-item form was established. Younger age, female sex, partnership status, and current employment were positively associated with higher social support scores. Norm values for the general sample and separately for sex and partnership status were reported.
The newly developed F-SozU K-3 is a reliable and valid screening instrument. It can be used as an economical alternative to previous longer instruments, especially in large scale surveys.
本研究的目的是通过缩短一份成熟的德语问卷（F-SozU K-6），开发并验证一种用于大规模调查中测量感知社会支持的简短筛查工具（F-SozU K-3）。
首先，基于2482名受访者的代表性样本，采用探索性和验证性因素分析，开发了一个简短的包含三个条目的F-SozU版本。其次，在一个独立的第二代表性人群样本（n = 2501）中对新开发的简短的包含三个条目的问卷进行评估和标准化。
确定了一个合适的包含三个条目的方案，具有良好的内部一致性（α = 0.89，ω = 0.89）。建立了跨性别和伴侣关系的完全不变性。建立了简短的包含三个条目的形式的结构效度。年龄较小、女性、伴侣关系状态和当前就业与较高的社会支持得分呈正相关。报告了一般样本以及按性别和伴侣关系状态分别的常模值。
新开发的F-SozU K-3是一种可靠且有效的筛查工具。它可以作为先前较长工具的经济替代方案，特别是在大规模调查中。
