This paper describes pre-injury and injury-related predictors of life satisfaction 3 months after injury for 563 of the 566 Māori participants in the POIS. The Te Whare Tapa Whā model of overall health and well-being was used to help inform the selection of post-injury life satisfaction predictor variables. Ninety-three percent of participants reported satisfaction with life pre-injury; 71% were satisfied with life at 3 months post-injury. In multivariate analysis for life satisfaction 3 months after injury, participants with an injury severity NISS >6 were less likely to be satisfied with life 3 months after injury compared with those with injury severities of NISS 1–3 (RR 0.80). In addition, those who were not satisfied with pre-injury social relationships or had poor general self-efficacy pre-injury were less likely to be satisfied with life 3 months after injury.
