To gain knowledge on psychosocial characteristics that predict the propensity of participation in longitudinal studies, attrition was analysed in a cohort of 3020 adolescents participating in the baseline survey of a longitudinal study with repeated followup focusing on adolescents' tobacco use. During the followup surveys, the proportion of responders was constantly at or above 90%. There were 941 adolescents (31.2%) who failed to participate in at least one of the six followup surveys. Boys had a fifty percent increased risk of nonparticipation compared with girls. Adolescents in families with experience of divorce, unemployment, and change of residence had a higher risk of nonparticipation. An increasing number of stressful life events during the previous year, uptake of tobacco use, number of friends, perceived performance at school, truancy, and alcohol use during the last term also independently associated with nonparticipation. Diverse psychosocial characteristics are independently associated with nonparticipation of youths in longitudinal studies.
为了解预测参与纵向研究倾向的心理社会特征，我们对3020名青少年组成的队列进行了失访分析，这些青少年参与了一项关于青少年烟草使用的纵向研究的基线调查，并进行了多次随访。在随访调查期间，应答者的比例一直保持在90%或以上。有941名青少年（31.2%）至少未参与六项随访调查中的一项。与女孩相比，男孩不参与的风险增加了50%。有离婚、失业和搬家经历的家庭中的青少年不参与的风险更高。前一年生活压力事件增多、开始使用烟草、朋友数量、在学校的自我认知表现、逃学以及上学期饮酒也与不参与独立相关。多种心理社会特征与青少年不参与纵向研究独立相关。
