Short-term work and nonwork stressor pile-up on parent and adolescent diurnal cortisol, physical symptoms, and sleep.","abstract":"= 465 daily observations with cortisol) were used to test the study hypotheses. Parent work stressor pile-up and adolescent stressor pile-up were associated with increased daily physical symptom likelihood in parents and adolescents, respectively. Counter to expectations, parent nonwork stressor pile-up was associated with steeper daily cortisol slopes. Additionally, we found curvilinear crossover effects for sleep quantity, such that parent nonwork stressor pile-up and adolescent stressor pile-up were associated with shorter sleep duration among adolescents and parents (respectively), but this relationship plateaued and reversed as daily pile-up increased to more extreme levels. Our article explores conceptual and operational pile-up definitions (level of analysis, length of time window, inclusion of the current-day stressor events). Individual-level analyses supported more consistent, positive linear relationships between stressor pile-up and strains. Time window had little consequences for conclusions, but inclusion of the current day yields some alternative conclusions. We discuss implications for understanding stressor pile-up across domains and across parent-child dyads as it relates to daily strain within the family system.
