Abstract
Adolescent well-being is increasingly scrutinized due to its decline. This study was conducted to validate a theory-driven instrument for the measurement of well-being needs with a sample of Dutch adolescents. The short (15-item) Social Production Function Instrument for the Level of well-being (SPF-ILs) measures whether a person’s needs for stimulation, comfort, behavioural confirmation, affection and status are met. In this study, its psychometric properties for adolescents were examined. Data collected in spring 2018 (T1) and spring 2019 (T2) from 1,304 Dutch adolescents (53.0% girls) aged 11–17 (mean, 13.7 ± 1.1) years were used. The instrument’s factor structure, internal consistency, construct validity, and gender and age factorial invariance were evaluated. The results showed that the SPF-ILs is valid and reliable for the assessment of adolescents’ well-being needs realisation. Confirmatory factor analyses supported the five-factor (stimulation, comfort, behavioural confirmation, affection and status) model, showing good internal consistency (α = 0.86 at T1, 0.88 at T2), convergent/divergent validity, as well as gender and age factorial invariance. Comparison across groups revealed the expected differences in the realisation of physical (comfort and stimulation) and social (behavioural confirmation, status and affection) well-being needs between girls and boys and over time. SPF-ILs use increases our understanding of how adolescents achieve well-being via the fulfilment of well-being needs. The maintenance of adolescents’ well-being is a global challenge, and this study revealed clear differences in adolescents’ realisation of well-being needs, increasing our understanding of what interventions are needed to support such realisation.
