Does Early Child Language Predict Internalizing Symptoms in Adolescence? An Investigation in Two Birth Cohorts Born 30 Years Apart

The role of language in mental health during the transition from primary to secondary education

We report a preregistered analysis to test whether children meeting diagnostic criteria for language disorder (LD) have higher self-reported and/or parent-reported mental health symptoms during the transition from primary to secondary education. Data are from a UK-based longitudinal cohort study, The Surrey Communication and Language in Education Study (SCALES). SCALES oversampled children at risk of LD at school entry. Language was measured using a battery of standardised assessments in Year 1 (age 5-6 years, n = 529), and mental health symptoms were measured using self and parent report in Year 6 (age 10-11 years, n = 384) and Year 8 (age 12-13 years, n = 246). Social experiences were also measured using self-report measures in Year 6. Mental health symptoms were stable during the transition from primary to secondary school. Symptom rates did not differ between children with and without LD based on self-report, but children with LD had higher parent-reported mental health symptoms than their peers with typical language. Similarly, early language was negatively associated with parent-reported but not self-reported mental health symptoms. Early language was associated with fewer child-reported positive social experiences in Year 6, but social experiences did not mediate the association between language and mental health. We found poor agreement between parent and self-reported child mental health symptoms across language groups. Future studies should aim to determine sources of disagreement between parent and child report, particularly for children with communication difficulties who may struggle to accurately self-report mental health symptoms.

Communication and Emotional Vocabulary; Relevance for Mental Health Among School-Age Youths

Background

The association between language and mental health may be connected to several aspects of language. Based on the known associations, emotional vocabulary could be an important contribution to mental health and act as a risk, protective or resilience factor for mental health in general. As a preliminary test of this hypothesis, an assessment of emotional vocabulary was constructed and used among youths in school age. Cross-sectional associations and prediction models with parent-reported youth mental health as outcome were examined for emotional vocabulary as well as general vocabulary, non-verbal problem solving and social communication, controlled for age, gender and subsamples.

Results

Emotional vocabulary, general vocabulary and non-verbal problem solving were directly associated with each other and similarly associated with age and gender. However, they were not significantly associated with social communication skills or mental health in the expected direction. Only social communication skills showed significant negative associations with behavioral mental health problems, suggesting these skills to be potential resources related to mental health.

Implication

Future research should investigate whether behavioral problems may be prevented or improved by developing better social communication skills among community school-age youths. However, our results suggest that merely expanding emotional vocabulary is not likely to produce such effects unless this is integrated with improving social communication.
