The Multidimensional Wellbeing in Youth Scale (MWYS): Development and Psychometric Properties_Syntax

Syntax for Study 1 and 3 In the present multi-sample mixed method study, we developed a novel assessment tool of youth wellbeing, the Multidimensional Wellbeing in Youth Scale (MWYS). In Study 1, an online survey study among Dutch-speaking adolescents and young adults (<em>N</em> = 339, <em>M</em>age = 18.44 years, <em>SD</em> = 3.53, 79 % females) was conducted to inspect which initial MWYS-items were viewed as being important for their wellbeing. In Study 2, we co-evaluated the original MWYS-items and co-created new items with adolescents and young adults (<em>N</em> = 25) via focus groups. In Study 3, we examined the validity and reliability of the updated MWYS in a new sample of Dutch-speaking adolescents and young adults (<em>N</em> = 239, <em>M</em>age = 19.68 years, <em>SD</em> = 4.40, 68 % females). Principal Components Analyses revealed five preliminary components of adolescent wellbeing: 1) having impact, purpose, and meaning; 2) dealing with stress and worry; 3) family relationships; 4) self-confidence; and 5) feeling respected, appreciated, and loved. These MWYS-components were related to other measures of mental health and wellbeing, and the MWYS showed good internal consistency and test-retest reliability. In conclusion, the MWYS was found to be a valid and reliable measure of youth wellbeing.

研究1与研究3的实施规范
在这项多样本混合方法研究中，我们开发了一款全新的青少年幸福感测评工具——青少年多维幸福感量表（Multidimensional Wellbeing in Youth Scale, MWYS）。
在研究1中，我们针对荷兰语使用者青少年与青年群体开展线上调查研究（有效样本量N=339，平均年龄Mage=18.44岁，标准差SD=3.53，女性占比79%），旨在探明初始版MWYS的哪些条目被受访者认为对自身幸福感至关重要。
研究2中，我们通过焦点小组访谈的形式，与25名青少年及青年共同评估了初始版MWYS条目，并协作开发了新的量表条目。
研究3中，我们在全新的荷兰语青少年与青年样本（N=239，平均年龄Mage=19.68岁，标准差SD=4.40，女性占比68%）中，对修订后的MWYS的效度与信度进行了检验。
主成分分析结果显示，青少年幸福感可初步划分为5个维度：1）拥有影响力、目标与意义感；2）应对压力与焦虑情绪；3）家庭关系；4）自信心；5）被尊重、被认可与被爱。
上述MWYS维度与其他心理健康及幸福感测评工具的结果存在显著关联，且MWYS表现出良好的内部一致性与重测信度。
综上，青少年多维幸福感量表（MWYS）是一款效度与信度俱佳的青少年幸福感测评工具。
