Associations between cortisol measures and psychosocial stressors at time 1 (age 11–14 years) and total Prodromal Questionnaire (PQ) score at time 2 (age 17–21 years). Added-variable plots showing relationships between the cortisol awakening response (A), diurnal cortisol (B), daily stressors (C), and negative life events (D) at time 1 and total PQ scores at time 2 as derived from the full model (Table 3). AUCg, area under the curve with respect to ground; AUCi, area under the curve with respect to increase; pc, principal component (score for first pc); sqrt, square root transformed.
