The main objective of the current study was to investigate the symptoms of social anxiety in Chinese adolescents by conducting latent profile analysis (LPA), a person-centered statistical approach, with items from the Social Anxiety Scale for Adolescents (SAS-A).
In total, a sample of 2,755 adolescents aged 11‒19 years were recruited from six urban public schools in the Beijing District and Sichuan Province, China. Latent profile analysis, regression mixture modelling, and multinomial logistical regression were adopted to investigate the latent profiles and profiles validity.
A four-profile model was suggested as the optimum: low group with diffuse social anxiety, moderate group with difficulties in new situations, moderate group with cognitive disturbance, and high group with diffuse social anxiety. With regression mixture modelling, results showed a greater possibility for older adolescents and girls fall into the high group with diffuse social anxiety. Finally, to examine the validity and interpretability of the social anxiety profiles, two cognitive factors-post-event rumination and self-focused attention-were adopted for their potential to significantly predict the moderate and high group social anxiety profiles.
The current study, which was the first effort to investigate the features of social anxiety among Chinese adolescents with LPA, supports an innovative model of social anxiety symptoms in a large, non-Western sample. Limitations and clinical implications are included.
本研究的主要目的是通过采用潜类分析（LPA），一种以人为中心的统计方法，使用青少年社交焦虑量表（SAS-A）的项目，来探讨中国青少年的社交焦虑症状。
共招募了来自中国北京市和四川省六所城市公立学校的 2755 名 11-19 岁的青少年。采用潜类分析、回归混合模型和多项逻辑回归来探讨潜在类别和类别有效性。
建议采用四种类别模型作为最优模型：低类别表现为弥漫性社交焦虑，中等类别表现为新情境困难，中等类别表现为认知障碍，高类别表现为弥漫性社交焦虑。通过回归混合模型，结果表明，年龄较大的青少年和女孩更有可能归入高类别表现为弥漫性社交焦虑。最后，为了检验社交焦虑类别的有效性和可解释性，采用了事后反刍和自我关注这两个认知因素，因为它们有可能显著预测中等和高类别社交焦虑类别的出现。
本研究首次采用潜类分析方法探讨了中国青少年的社交焦虑特征，支持了一种在大型非西方样本中社交焦虑症状的创新模型。本研究还包括了局限性和临床意义。
