Comorbidity between anxiety and depression symptoms is often high in children. Person-oriented statistical approaches are useful to detect heterogeneity of individuals and diverse patterns of response to treatment. This study aimed to explore the different profiles in a sample of Spanish children who received the Super Skills for Life (SSL) transdiagnostic program, to identify which profile of individuals benefited most from the intervention and the likelihood of transition of symptom patterns over time. Participants were 119 children (42.9% were female) aged 8–12 years old (M = 9.39; SD = 1.26). Children completed anxiety and depression measures at the baseline, postintervention, and 12-months follow-up. Results from latent transition analysis (LTA) revealed two groups depending on the severity of the anxiety and depression symptoms: low symptoms (LS) and high symptoms (HS). LS group remained stable and HS decreased by 25%, switching to the LS group. Children with greater social anxiety benefited most from the program over time. Furthermore, older children were more likely to improve rapidly one year after the intervention compared to younger children. This study provides information to consider when implementing preventive interventions for schoolchildren and to tailor them according to the target population characteristics to increase their effectiveness.

焦虑和抑郁症状之间的合并症在儿童中通常很高。以人为本的统计方法有助于检测个体的异质性和对治疗的不同反应模式。本研究旨在探索接受超级生活技能 (SSL) 跨诊断计划的西班牙儿童样本中的不同特征，以确定哪些个体特征从干预中受益最大，以及症状模式随时间转变的可能性。参与者为 8-12 岁的 119 名儿童（42.9% 为女性）（M = 9.39；SD= 1.26)。儿童在基线、干预后和 12 个月的随访中完成了焦虑和抑郁测量。潜在转换分析 (LTA) 的结果根据焦虑和抑郁症状的严重程度揭示了两组：低症状 (LS) 和高症状 (HS)。LS组保持稳定，HS下降25%，转为LS组。随着时间的推移，社交焦虑程度较高的儿童从该计划中受益最多。此外，与年龄较小的儿童相比，年龄较大的儿童在干预一年后更有可能迅​​速改善。本研究提供了在对学童实施预防性干预措施时需要考虑的信息，并根据目标人群特征对其进行调整以提高其有效性。
