Reactive and Regulatory Temperament: Longitudinal Associations with Internalizing and Externalizing Symptoms through Childhood.

ABSTRACT: Previous studies of the relationship between temperament and psychopathology have been limited by focusing on main effects of temperament on psychopathology, reliance solely on maternal reports of child temperament, and predominately using cross-sectional designs. This study extended this work by focusing on interactions between reactive (positive emotionality/PE; negative emotionality/NE) and regulatory (effortful control) dimensions of temperament, using laboratory observations of temperament, and focusing on longitudinal prediction of internalizing and externalizing behavior problems. 536 children (46.1% Female, 92.4% White) were followed in a prospective, longitudinal study of the relationship between temperament and psychopathology. Temperament was assessed using laboratory observations when children were at age 3. Mothers and fathers reported on internalizing and externalizing symptoms in their children at ages 3, 6, and 9. Multilevel modeling analyses examined associations between the interaction of temperament traits and patterns of change in internalizing and externalizing psychopathology. Interactions between reactive PE traits (Sociability, Exuberance), but not NE traits (Dysphoria, Fear), and regulatory temperament (Disinhibition) were associated with the slope of maternal-reported internalizing and paternal-reported externalizing symptoms such that youth low in PE traits and high in effortful control experienced a greater decline in symptoms over time. In conclusion, among children with lower levels of PE traits, strong regulatory abilities are associated with greater reductions in internalizing and externalizing symptoms over time. These models highlight the complex interaction between reactive and regulatory temperament and expand current understanding of temperamental risk for psychopathology.

Project description:ImportanceLittle is known about the long-term economic and social outcomes for children with longitudinally assessed comorbid externalizing and internalizing symptoms, especially compared with children with externalizing symptoms or internalizing symptoms only.ObjectiveTo examine the association between childhood trajectories of externalizing, internalizing, and comorbid symptoms and long-term economic and social outcomes.Design, setting, and participantsA 32-year prospective cohort study linked with administrative data was conducted in school-aged participants aged 6 to 12 years in the Québec Longitudinal Study of Kindergarten Children (N = 3017) followed up from 1985 to 2017. Data analysis was conducted between August 1, 2021, and March 31, 2022.ExposuresTeacher-rated behavioral symptoms were used to categorize children from age 6 to 12 years into developmental profiles using group-based trajectory modeling.Main outcomes and measuresMultivariable regression models were used to test the association between childhood symptom profile group and adult employment earnings, welfare receipt, intimate partnership status, and having children living in the household. Participant sex, IQ, and socioeconomic background were adjusted for.ResultsOf 3017 participants in this sample, 1594 (52.8%) were male and 1423 (47.2%) were female. Per confidentiality rules established by Statistics Canada, income variables were rounded to base 100 and count variables were rounded to base 10; the mean (SD) age was 37 (0.29) years at follow-up. Four symptom profiles were identified: no/low (n = 1369 [45.4%]), high externalizing (882 [29.2%]), high internalizing (354 [11.7%]), and comorbid (412 [13.7%]) symptoms. Compared with the no/low symptom profile, participants in the high externalizing-only profile earned $5904 (95% CI, -$7988 to -$3821) less per year and had 2.0 (95% CI, 1.58-2.53) times higher incidence of welfare receipt, while participants in the high internalizing group earned $8473 (95% CI, -$11 228 to -$5717) less per year, had a 2.07 (95% CI, 1.51-2.83) higher incidence of welfare receipt, and had a lower incidence of intimate partnership (incident rate ratio [IRR], 0.89; 95% CI, 0.80-0.99). Participants in the comorbid profile fared especially poorly: they earned $15 031 (95% CI, -$18 030 to -$12 031) less per year, had a 3.79 (95% CI, 2.75-5.23) times higher incidence of annual welfare receipt, and were less likely to have an intimate partner (IRR, 0.71; 95% CI, 0.63-0.79) and children living in the household (IRR, 0.86; 95% CI, 0.80-0.92). Estimated lost earnings over a 40-year working career were $140 515 for the high externalizing, $201 657 for the high internalizing, and $357 737 for the comorbid profiles.Conclusions and relevanceIn this cohort study, children exhibiting sustained childhood high externalizing, high internalizing, or comorbid symptoms were at increased risk of poor economic and social outcomes into middle age. These findings suggest that children exhibiting comorbid problems were especially vulnerable and that early detection and support are indicated.

Project description:ImportanceMental health problems in early life are associated with labor market marginalization, especially in youths with persistent internalizing and externalizing problems. However, previous research has not adjusted for familial (genetic and shared environmental) factors.ObjectiveTo examine associations of early-life internalizing and externalizing problems with adulthood unemployment and work disability, adjusting for familial factors.Design, setting, and participantsThis population-based prospective cohort study included Swedish twins who were born in 1985-1986 and surveyed at 4 consecutive waves across childhood and adolescence until 2005. Through linkage to nationwide registries, participants were followed up from 2006 to 2018. Data analyses were conducted between September 2022 and April 2023.ExposuresInternalizing and externalizing problems, assessed with the Child Behavior Checklist. Participants were differentiated regarding duration of internalizing and externalizing problems (persistent, episodic, and noncases).Main outcomes and measuresUnemployment (180 days or more of being unemployed) and work disability (60 days or more of being sickness absent or disability pensioned) during follow-up. Cox proportional hazards regression models were calculated to obtain cause-specific hazard ratios (HRs) with 95% CIs in the whole cohort and exposure-discordant twin pairs.ResultsOf 2845 participants, 1464 (51.5%) were female. Incident unemployment was experienced by 944 (33.2%) and incident work disability by 522 (18.3%) participants. Compared with noncases, persistent internalizing problems were associated with unemployment (HR, 1.56; 95% CI, 1.27-1.92) and work disability (HR, 2.32; 95% CI, 1.80-2.99). Similarly, compared with noncases, persistent externalizing problems were associated with unemployment (HR, 1.87; 95% CI, 1.55-2.26) and work disability (HR, 2.38; 95% CI, 1.87-3.03). Persistent cases had overall higher risks of adverse outcomes than episodic cases. After adjustment for familial factors, associations with unemployment were no longer statistically significant, whereas associations with work disability remained or were only slightly reduced.Conclusions and relevanceIn this cohort study of young Swedish twins, familial factors explained the associations between early-life persistent internalizing and externalizing problems and unemployment; such factors were comparatively less important for the association with work disability. This suggests nonshared environmental factors may be important for the risk of future work disability among young individuals with persistent internalizing and externalizing problems.
