Using data from a longitudinal study, the present study employed a latent class mover-stayer analytical strategy to examine both the cross-sectional and longitudinal (+33 months) relationship between membership of stress classes, and subjective life expectancy. Participants were from 21 High schools in Scotland and Northern Ireland. Data were collected in the first year of High school (mean age = 12.5 years), and at +33 months (fourth year, or school year 11). Sample 1 consisted of 1171 adolescents (40.82% females, 2.56% unreported) in Northern Ireland. Sample 2 consisted of 1059 adolescents (52.79% females, 1.32% unreported) in Scotland. Adolescents with the lowest levels of stress projected the highest subjective life expectancy scores. Longitudinal analyses were jumbled and not in keeping with cross-sectional results. More research may be needed on the trajectory of subjective life expectancy over time before it can be depended upon as a reliable outcome variable in adolescent development.
利用一项纵向研究的数据，本研究采用潜在类别转变者-留存者分析策略，同时考察了压力类别成员身份与主观预期寿命之间的横断面和纵向（+33 个月）关系。参与者来自苏格兰和北爱尔兰的 21 所高中。数据在高中第一年（平均年龄为 12.5 岁）和+33 个月（第四年，即 11 年级）收集。样本 1 由北爱尔兰的 1171 名青少年（40.82%为女性，2.56%未报告）组成。样本 2 由苏格兰的 1059 名青少年（52.79%为女性，1.32%未报告）组成。压力水平最低的青少年预测的主观预期寿命得分最高。纵向分析混乱，与横断面结果不一致。在将主观预期寿命作为青少年发展的可靠结果变量之前，可能需要对其随时间的轨迹进行更多研究。
