摘要:
目的 探讨社会支持与学校联结对青少年自我效能感发展轨迹的影响,并分析其群组效应,为增强青少年自我效能感提供依据。 方法 采用整群随机抽样法,于2023年10月(T1)、2024年4月(T2)、2024年10月(T3)选取湖南省湘西自治州4所中学930名在校初一学生进行3次追踪调查,使用自我效能感量表(GSES)、社会支持量表(SSS)、学校联结量表(SCS)进行问卷调查,运用潜变量增长混合模型(LGMM)分析青少年自我效能感的不同类别,采用多元Logistic回归分析青少年自我效能感发展轨迹与社会支持和学校联结的关联。 结果 青少年自我效能感发展轨迹分为3个类别,类别1为低效能-快速增长组(53名,6.6%),类别2为中效能-平稳增长组(793名,84.1%),类别3为高效能-快速下降组(84名,9.3%)。以低效能-快速增长组为参考,社会支持水平高的学生归为中效能-平稳增长组(OR=1.06,95%CI=1.03~1.08)和高效能-快速下降组(OR=1.06,95%CI=1.03~1.09)的概率大,学校联结水平高的学生归为高效能-快速下降组(OR=1.10,95%CI=1.03~1.18)的概率大(P值均 < 0.05)。以是否住宿分组,低效能-快速增长组自我效能感T1(t=2.10)与高效能-快速下降组社会支持(t=-2.15)均出现群组效应(P值均 < 0.05);以是否独生子女分组,中效能-平稳增长组自我效能感T2(t=2.05)出现群组效应(P < 0.05)。 结论 青少年自我效能感发展轨迹具有群体异质性,住宿和独生子女在青少年自我效能感发展轨迹上存在群组效应。增强社会支持和学校联结有助于提高青少年自我效能感。 Abstract:Objective To explore the influence of social support and school connectedness on the developmental trajectory of self-efficacy in adolescents and analyze its subgroup effects, so as to provide a basis for enhancing adolescents' self-efficacy. Methods Using a cluster random sampling method, 930 first-year middle school students from four schools in Xiangxi Autonomous Prefecture, Hunan Province, were selected for three longitudinal surveys in October 2023 (T1), April 2024 (T2), and October 2024 (T3). The General Self-efficacy Scale (GSES), Social Support Scale (SSS), and School Connectedness Scale (SCS) were administered. Latent growth mixture modeling (LGMM) was used to identify different developmental trajectories of self-efficacy in early adolescence. Multivariate Logistic regression was employed to examine the associations of self-efficacy trajectories with social support and school connectedness in adolescents. Results The developmental trajectory of self-efficacy in adolescents was classified into three categories: category 1 was low efficacy-rapid growth group (53 students, 6.6%), category 2 was moderate efficacy-stable growth group (793 students, 84.1%), and category 3 was high efficacy-rapid decline group (84 students, 9.3%). Using the low efficacy-rapid growth group as the reference, students with higher social support were more likely to belong to the moderate efficacy-stable growth group (OR=1.06, 95%CI=1.03-1.08) and the high efficacy-rapid decline group (OR=1.06, 95%CI=1.03-1.09), students with higher school connectedness were more likely to belong to the high efficacy-rapid decline group (OR=1.10, 95%CI=1.03-1.18) (all P < 0.05). Subgroup analysis revealed significant effects for boarding status (low efficacy-rapid growth group at T1, t=2.10; high efficacy-rapid decline group in social support, t=-2.15) and only-child status (moderate efficacy-stable growth group at T2, t=2.05) (all P < 0.05). Conclusions The developmental trajectory of self-efficacy in adolescents exhibits group heterogeneity, with boarding status and only-child status showing subgroup effects. Enhancing social support and school connectedness can help improve self-efficacy in adolescents. -
