This article reports on a 2-year follow-up study (443 Algerian children). Using a variety of satisfaction measures, along with detailed questions relating to family, school, local area, material deprivation, and daily activities, we aim to explore changes in the self-reported well-being of children from age 12 to 14. Satisfaction with health and friends remained stable, meanwhile satisfaction with school decreased more for boys than for girls, but satisfaction with family, time use, and material possessions decreased for girls. This pattern was further confirmed by children's reports on the selected activities, experiences, and facilities provided to them. Regression analyses indicated that satisfaction with material possessions predicted satisfaction with life and positive affect, meanwhile satisfaction with family life and friends predicted eudaimonia.
