This article examines factors associated with adolescent self-concept and the impact of adolescent self-concept on psychological and physical health and health behaviour in young adulthood.
The data are from the household cross-sectional (1994/95) and longitudinal (1994/95 to 2000/01) components of Statistics Canada's National Population Health Survey.
Scores on self-concept indicators in 1994/95 were compared between the sexes and age groups (12 to 15 versus 16 to 19). Multivariate analyses were used to examine cross-sectional and longitudinal associations between adolescent self-concept and depression, self-perceived health, physical activity and obesity, controlling for other possible confounders.
Self-concept tends to be low among girls compared with boys. Cross-sectionally, adolescent self-concept was associated with household income and emotional support. For girls and for young adolescents, a weak self-concept in 1994/95 was related to the incidence of depression over the next six years; it was also predictive of physical inactivity among boys, and obesity among both sexes. A strong self-concept had a positive long-term effect on girls' self-perceived health.
本文探讨与青少年自我概念相关的因素，以及青少年自我概念对青年期心理和身体健康及健康行为的影响。
数据来自加拿大统计局全国人口健康调查的家庭横断面（1994/95年）和纵向（1994/95年至2000/01年）部分。
比较了1994/95年不同性别和年龄组（12至15岁与16至19岁）自我概念指标的得分。采用多变量分析来研究青少年自我概念与抑郁、自我感知健康、体育活动和肥胖之间的横断面和纵向关联，并控制其他可能的混杂因素。
与男孩相比，女孩的自我概念往往较低。横断面研究表明，青少年自我概念与家庭收入和情感支持有关。对于女孩和青少年，1994/95年自我概念薄弱与未来六年的抑郁症发病率有关；它还预示着男孩缺乏体育活动，以及男女两性的肥胖情况。强大的自我概念对女孩的自我感知健康有积极的长期影响。
