Table 5. Population attributable risk proportions (PARPs)* of lifetime DSM-IV/CIDI disorder types associated with childhood adversities by life course stage.

Overall Childhood (ages 4-12) Adolescence (ages 13-19) Early adulthood (ages 20-29) Middle-later adulthood (ages 30+)

Mood 26.2 57.1 30.5 24.7 20.5
Anxiety 32.4 39.5 28.7 31.3 29.8
Substance 21.0 26.1 25.6 32.1
Disruptive behavior 41.2 34.4 38.9
Any 32.4 44.6 32.0 28.6 25.9

PARPs were calculated using simulation methods to generate individual-level predicted probabilities of the outcome disorders twice from the coefficients in the best-fitting model: the first time using all the coefficients in the model (probability of disorder among those exposed to CAs) and the second time assuming that the coefficients associated with the CAs were all zero (probability of disorder among those unexposed). One minus the ratio of the predicted prevalence estimates in the two specifications was then used to calculate PARP. In the pooled dataset, the PARP value is the average PARP across all disorders included in the calculation based on a constant model across disorders.

Too few cases available in cells to estimate PARP.

Disruptive Behavior Disorders are restricted to respondents <= 44 years of age at interview
