Insights
Low socioeconomic status (SES) is linked to more childhood emotional disorders. This study finds that pessimistic thinking, influenced by adversity, contributes to this link in children.
Area of Science:
- Child Psychology
- Developmental Psychology
- Social Determinants of Health
Background:
- Low socioeconomic status (SES) is correlated with increased rates of emotional disorders in children.
- Cognitive biases, such as pessimism, may contribute to the disparity in mental health outcomes between different SES groups.
Purpose of the Study:
- To investigate the role of cognitive bias, specifically pessimistic attributional style, in mediating the relationship between SES and emotional disorders in children.
- To examine whether persistent, pervasive adversity mediates the link between SES and pessimism.
Main Methods:
- Assessed attributional style (pessimism) and childhood emotional problems in 341 9-year-olds across a wide SES range.
- Measured SES using income-to-needs ratio, poverty history, and parental education.
- Examined mediation pathways involving SES, adversity, pessimism, and emotional problems.
Main Results:
- Lower SES children exhibited a higher prevalence of pessimistic attributional style (effect sizes 0.18-0.24).
- Persistent, pervasive adversity predicted pessimism and mediated the SES-pessimism association.
- Pessimistic attributional style mediated the relationship between SES and childhood emotional problems.
Conclusions:
- Pessimism, exacerbated by adversity, plays a significant role in the link between low SES and childhood emotional disorders.
- Interventions targeting cognitive biases may help mitigate mental health disparities associated with socioeconomic disadvantage.
Abstract:
Low socioeconomic status (SES) is associated with higher rates of emotional disorders in childhood and beyond. Here we assessed one possible contributor to this disparity, a cognitive bias in the interpretation of negative events, in a group of 341 9-year-olds (49% female, 94% White) ranging widely in SES. This cognitive bias, known as pessimism in the attributional style literature, is the tendency to interpret negative events as persistent (Stable) and pervasive (Global). It was found to be more common among lower SES children (effect sizes = 0.18-0.24 depending on SES measures: income to needs ratio, proportion of poverty from birth to age 9, and parental educational attainment). Moreover, persistent, pervasive adversity in children's lives predicted this bias and mediated the SES-pessimism link. Pessimistic attributional style, in turn, was related to childhood emotional problems and mediated the relation between SES and these problems. Finally, evidence for serial mediation of the SES-mental health problems relationship was found via persistent, pervasive adversity and pessimism, respectively.
