In this systematic review, we assessed available evidence for cross-cultural measurement invariance of assessment scales for child and adolescent psychopathology as an indicator of cross-cultural validity. A literature search was conducted using the Medline, PsychInfo, Scopus, Web of Science, and Google Scholar databases. Cross-cultural measurement invariance data was available for 26 scales. Based on the aggregation of the evidence from the studies under review, none of the evaluated scales have strong evidence for cross-cultural validity and suitability for cross-cultural comparison. A few of the studies showed a moderate level of measurement invariance for some scales (such as the Fear Survey Schedule for Children-Revised, Multidimensional Anxiety Scale for Children, Revised Child Anxiety and Depression Scale, Revised Children's Manifest Anxiety Scale, Mood and Feelings Questionnaire, and Disruptive Behavior Rating Scale), which may make them suitable in cross-cultural comparative studies. The remainder of the scales either showed weak or outright lack of measurement invariance. This review showed only limited testing for measurement invariance across cultural groups of scales for pediatric psychopathology, with evidence of cross-cultural validity for only a few scales. This study also revealed a need to improve practices of statistical analysis reporting in testing measurement invariance. Implications for future research are discussed.

Summary: This study evaluated the effects of depression and anxiety disorder symptoms on the health‐related quality of life (HRQOL) of children and adolescents with epilepsy. Sixty children and adolescents and their parents participated in the study. Symptoms of anxiety disorders were identified by the Screen for Child Anxiety Related Emotional Disorders questionnaire (SCARED) and symptoms of depression by the Mood and Feeling Questionnaire (MFQ). The Pediatric Quality of Life Inventory (PedsQL) was used for HRQOL assessments. A series of simple and partial correlations revealed that the levels of HRQOL significantly decrease as symptoms of depression or anxiety disorders increase and vice versa. Stepwise regression method of children’s ratings resulted in a final model of school achievement and symptoms of generalized anxiety and separation anxiety disorder as predictors that explain 50.9% of the variation in HRQOL (F = 11.21, p < 0.000). For parents’ ratings, the final model included symptoms of depression and separation anxiety disorder as predictors that explain 38.4% of the variation in HRQOL (F = 10.82, p < 0.000). In summary, symptoms of depression and generalized and separation anxiety disorders have the most significant impact on HRQOL.

Aims.: This study evaluated the measurement invariance of the strengths and difficulties questionnaire (SDQ) self-report among adolescents from seven different nations.Methods.: Data for 2367 adolescents, aged 13–18 years, from India, Indonesia, Nigeria, Serbia, Turkey, Bulgaria and Croatia were available for a series of factor analyses.Results.: The five-factor model including original SDQ scales emotional symptoms, conduct problems, hyperactivity–inattention problems, peer problems and prosocial behaviour generated inadequate fit degree in all countries. A bifactor model with three factors (i.e., externalising, internalising and prosocial) and one general problem factor yielded adequate degree of fit in India, Nigeria, Turkey and Croatia. The prosocial behaviour, emotional symptoms and conduct problems factor were found to be common for all nations. However, originally proposed items loaded saliently on other factors besides the proposed ones or only some of them corresponded to proposed factors in all seven countries.Conclusions.: Due to the lack of a common acceptable model across all countries, namely the same numbers of factors (i.e., dimensional invariance), it was not possible to perform the metric and scalar invariance test, what indicates that the SDQ self-report models tested lack appropriate measurement invariance across adolescents from these seven nations and it needs to be revised for cross-country comparisons.
