This study aims to investigate the influence of household unpredictability on HPA axis functioning and emotional distress in early childhood.
Sample of 44 children averaging 5.44 years assessed using the CHAOS scale for household unpredictability.
Cortisol levels measured through salivary samples collected at three time points to evaluate HPA axis activation.
Hierarchical regressions analyzed the relationship between household chaos and cortisol reactivity, controlling for age, sex, threat, and deprivation.
No significant associations found between household chaos and cortisol levels or emotional distress.
No evidence for cortisol mediation between household chaos and distress.
Exploratory analyses highlighted inconsistencies in cortisol collection across participants.
