Children and adolescents are increasingly susceptible to issues related to anxiety and depression symptoms. The literature does not present a consensus on the composition of indicators that make predictions, prognostic algorithms, or management strategies in mental health promotion and prevention. Most studies primarily focus on the consequences observed in adulthood. This study develops a multidimensional representation of the propensity of children and adolescents to have difficulties in the field of anxiety and depression. The Ordered Weighted Averaging (OWA) operator was used to create a composite indicator, and three quality tests validated the results. For this, it uses information about different dimensions associated with adversity in childhood and adolescence from 54 countries sourced from UNICEF’s Multiple Indicator Cluster Surveys to compare the values of proposed dimensions across continents. The generated composite indicator reveals that, on average, countries in Africa show a higher propensity for children and adolescents to present difficulties in the anxiety and depression fields. In the opposite position, the Americas have the lowest average propensity for these mental health conditions. The validation of the results through quality tests reinforces confidence in the direction indicated by the findings, enhancing the decision-making process when dealing with multidimensional phenomena.儿童及青少年愈发容易受到焦虑与抑郁相关症状类心理问题的影响。现有文献对于心理健康促进与预防领域中用于预测的指标构成、预后算法及管理策略尚未形成统一共识。绝大多数研究主要聚焦于成年群体中观测到的心理后果。本研究针对儿童及青少年罹患焦虑与抑郁相关困境的易感性，构建了多维表征体系。本研究采用有序加权平均（Ordered Weighted Averaging, OWA）算子构建综合指标，并通过三项质量检验验证研究结果。为此，本研究依托联合国儿童基金会（UNICEF）多指标类集调查（Multiple Indicator Cluster Surveys, MICS）的数据，纳入来自54个国家的儿童及青少年期逆境相关多维度信息，用以对比不同大洲的所提出的维度得分。所生成的综合指标显示，非洲国家的儿童及青少年在焦虑与抑郁相关领域出现困境的平均易感性更高。与之相反，美洲地区的此类心理健康问题平均易感性最低。通过质量检验完成的结果验证，进一步强化了研究发现所指向结论的可信度，可为处理多维心理现象的决策流程提供支撑。
