Data Publication for: A Brief Measure of Complete Subjective Well-Being in Germany: A Population-Based Validation of a German Version of the Flourish Index (FI) and the Secure Flourish Index (SFI)

Measuring subjective well-being in a multidimensional, valid, reliable, and parsimonious way is important for both social science research and social policy. Here, we present an efficient measure of distinct domains of subjective well-being and overall flourishing. The Flourishing Index (FI) consists of five sub-domains: 1. happiness and life satisfaction, 2. physical and mental health, 3. meaning and purpose, 4. character and virtue, and 5. close social relationships. The Secure Flourishing Index (SFI) adds the sub-domain financial and material stability, which is thought to be necessary to sustain the other domains over time. We developed a German version of these measures in a multi-stage translation and scale testing process. The results of an exploratory factor analysis in Study 1 (N=192) suggest a unidimensional structure of the FI and a two-dimensional structure of the SFI. Moreover, both indices (and most sub-domains) revealed acceptable to good reliability. The factor structures were confirmed in Study 2 (N=13,268). We provide indications for measurement invariance of both indices with regard to gender and age. We furthermore examined inter-correlations with related constructs such as importance of health, self-efficacy, and social support. Study 3 (N=317) finds evidence for high convergent validity of both the FI and the SFI with overall well-being as well as sub-scores of the PERMA-Profiler. These results suggest that the FI and the SFI are efficient measures of distinct domains of subjective well-being and overall flourishing. Our translation of the FI and SFI, along with the empirical relationships that we found among the measures that we reviewed, will help scholars in Germany (and beyond) explore an expanded range of domains of well-being, including the comparatively neglected domains of character and virtue, physical health, and financial and material stability.

以多维度、有效、可靠且简约的方式衡量主观幸福感（subjective well-being），无论是对于社会科学研究还是社会政策制定而言都具有重要意义。本文提出了一种针对主观幸福感不同维度以及整体幸福充盈状态的高效测评工具。幸福充盈指数（Flourishing Index, FI）包含五个子维度：1. 幸福感与生活满意度；2. 生理与心理健康；3. 意义与目标；4. 品格与德行；5. 亲密社会关系。安全型幸福充盈指数（Secure Flourishing Index, SFI）则新增了财务与物质稳定性这一子维度，该维度被认为是长期维持其他子维度的必要条件。本研究通过多阶段翻译与量表测试流程，开发了上述测评工具的德语版本。研究1（N=192）的探索性因素分析结果显示，FI为单维结构，而SFI为二维结构。此外，两项指数（以及大部分子维度）均表现出可接受至优秀的信度水平。研究2（N=13268）验证了上述因素结构。本研究还证实了两项指数在性别与年龄维度上的测量恒定性。此外，本研究还考察了两项指数与健康重要性、自我效能感（self-efficacy）以及社会支持等相关构念之间的相关关系。研究3（N=317）的结果表明，FI与SFI均与整体幸福感以及PERMA-Profiler的子维度得分具有较高的聚合效度。上述结果证实，FI与SFI均为针对主观幸福感不同维度以及整体幸福充盈状态的高效测评工具。本研究开发的FI与SFI德语版本，结合我们所梳理的测评工具间的实证关联，将有助于德国乃至全球学者拓展幸福感维度的研究范畴，包括此前相对被忽视的品格与德行、生理健康以及财务与物质稳定性等维度。
