Children’s ego-resilience (within-person capacities that facilitate psychological resistance) and irritability (increased proneness to experience negative affective states following environmental stressors) are critical determinants of their mental health. Here, we investigated how ego-resilience engages with irritability when linked to symptoms of anxiety and depression. We analyzed cross-sectional survey data from a combined clinical and nonclinical sample. Overall, 228 children ( Mage = 12.52, SDage = 2.69; 41.7% female) reported on symptoms of depression/anxiety, ego-resilience, and irritability. Moderated hierarchical regression analyses showed that ego-resilience was negatively associated with symptoms of anxiety and depression and that irritability was positively related to heightened symptom levels. Ego-resilience and irritability had overall stronger associations with symptoms of depression than anxiety. Irritability moderated the association between ego-resilience and depression, such that the effects of ego-resilience were stronger among highly irritable children. We discuss our findings within environmental and biological sensitivity frameworks. Future research must substantiate our findings and determine whether sensitivity frameworks help better understand the potentially interrelated impact of ego-resilience with irritability on children’s mental health.
Anxiety and depression are among the disorders with highest prevalence during childhood. Previous research has substantiated that individual’s high irritability promotes the occurrence of associated symptoms while high ego-resilience protects against them. So far, little is known about how ego-resilience could engage with irritability for symptom development. We investigated interactional effects of irritability with ego-resilience on symptoms of anxiety and depression. Overall, 228 children from a combined clinical and nonclinical sample aged 7 to 18 years participated in a cross-sectional self-report survey. They reported on internalizing symptoms, ego-resilience, and irritability. A moderated hierarchical regression analysis showed that ego-resilience was negatively associated with symptoms of anxiety and depression, and that irritability was positively related to heightened symptom levels. Ego-resilience and irritability were overall stronger associated with symptoms of depression than anxiety. Irritability moderated the association between ego-resilience and depression such that effects of ego-resilience were stronger among highly irritable participants. Our results suggest that highly irritable children could benefit to a larger extent from ego-resilience capacities, possibly yielding a protective role of irritability for buffering internalizing symptoms. Our findings highlight differential psychopathological mechanisms that underlie depression and anxiety. They also pinpoint to a dynamic systems approach when assessing determinants of psychopathology which are traditionally interpreted as either risk-increasing or protective. Furthering research that considers irritability within environmental/biological sensitivity frameworks could help better understanding our findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
