Abstract

The World Health Organization five-item Well-Being Index has been widely used to assess adolescents' well-being. However, its structural properties and measurement invariance at both between- and within-country levels have been underexamined in this population. The present study aimed to fill this gap. Relying on a nationally representative sample of 9,007 school attendees in Luxembourg (M_AGE = 14.7; SD_AGE = 2.4; 48.7% female) and on both classical test theory and item response theory, I assessed the scalability, reliability, monotonicity, factorial structure, convergent validity, and sociodemographic measurement invariance of the WHO-5. Measurement invariance was investigated across groups differing in terms of academic performance, country of birth, language, sex, socioeconomic status, and type of school. The WHO-5 exhibited strong scalability (Loevinger's H = .550) as well as satisfactory reliability (McDonald's ω = .84), monotonicity, factorial validity, and convergent validity. Measurement invariance held across all the examined subgroups. This study suggests that the WHO-5 is a sound, unidimensional measure of well-being that can be used for comparisons across various sociodemographic adolescent groups.

卢森堡青少年WHO-5幸福指数的心理测量评价和社会人口测量不变性。

世界卫生组织的五项幸福指数被广泛用于评估青少年的幸福。然而，在这一人群中，其结构特性和国家之间和国家内部水平的测量不变性尚未得到充分研究。本研究旨在填补这一空白。根据卢森堡9,007名学校参与者的全国代表性样本（MAGE = 14.7; SDAGE = 2.4； 48.7%为女性），以及经典测试理论和项目反应理论，我评估了WHO-5的可扩展性、可靠性、单调性、因子结构、收敛效度和社会人口学测量不变性。测量的不变性在不同的学习成绩、出生国家、语言、性别、社会经济地位和学校类型的群体中进行了调查。WHO-5具有较强的可扩展性（Loevinger’s H = 0.550），令人满意的信度（McDonald’s ω = 0.84）、单调性、析因效度和收敛效度。在所有被检查的子组中保持测量不变性。这项研究表明，世卫组织-5是一种可靠的、单向度的福祉衡量标准，可用于不同社会人口统计学青少年群体之间的比较。

期刊介绍： The Journal of Personality Assessment (JPA) primarily publishes articles dealing with the development, evaluation, refinement, and application of personality assessment methods. Desirable articles address empirical, theoretical, instructional, or professional aspects of using psychological tests, interview data, or the applied clinical assessment process. They also advance the measurement, description, or understanding of personality, psychopathology, and human behavior. JPA is broadly concerned with developing and using personality assessment methods in clinical, counseling, forensic, and health psychology settings; with the assessment process in applied clinical practice; with the assessment of people of all ages and cultures; and with both normal and abnormal personality functioning.
