Low mood, worry and mind wandering in children.

Previous research with adults and adolescents has established that mind wandering-characterized by a shift in attention from external tasks to internal thoughts-is associated with negative affect and reduced psychological well-being, particularly when focused on past events. This study explored the relations between low mood, worry, and the frequency and temporal orientation of mind wandering in children aged 8-12 years (N = 77). In a testing session conducted via videoconferencing software, we assessed mind wandering using intermittent thought probes during a listening activity and collected mood and worry data through self-report questionnaires and carer reports. Our findings indicate that children's minds wandered approximately 23% of the time, aligning with existing literature. We found a significant association between lower mood and increased mind wandering. Specifically, children with lower mood showed a higher propensity for mind wandering. Moreover, low mood was a significant predictor of past-oriented mind wandering, and a significant relation was observed between worry and future-oriented thought. These results highlight the need for future research using experimental designs to clarify the causal relationships between children's mood, worry, and mind wandering. A deeper understanding of these dynamics is essential for developing targeted interventions that aim to enhance emotional well-being in children.
