Factors associated with trajectories of psychological distress for Australian fathers across the early parenting period

Purpose: Little is known about the course of fathers' psychological distress and associated risk factors beyond the postnatal period. Therefore, the current study aimed to: (a) assess the course of distress over 7 years postnatally; (b) identify classes of fathers defined by their symptom trajectories; and (c) identify early postnatal factors associated with persistent symptoms. Method: Data from 2,470 fathers in the Longitudinal Study of Australian Children were analysed using latent growth modelling. Fathers' psychological distress was assessed using the Kessler-6 (Kessler et al. in Arch Psychiatry 60:184-189, 2003) when their children were aged 0-1, 2-3, 4-5 and 6-7 years. Results: Overall, distress was highest in the first postnatal year and then decreased over time. Two distinct trajectories were identified. The majority of fathers (92 %) were identified as having minimal distress in the first postnatal year which decreased over time, whilst 8 % had moderate distress which increased over time. Low parental self-efficacy, poor relationship and job quality were associated with 'persistent and increasing distress'. Conclusions: Early postnatal factors associated with fathers' persistent distress were identified, providing opportunities for early identification and targeted early intervention.
