SB Stanford–Binet, IQ intelligence quotient, MHT Moray House test. Multivariate results were derived from a generalised linear model including all predictors showing a bivariate association of p < 0.1. The combined total of early-life stressors was modelled separately from the contributing totals of childhood and early-adulthood stressors. Significant results at p < 0.05 (without correcting for multiple comparisons) are highlighted in bold
