The Refugee Integration Survey and Evaluation (RISE) study assessed refugee integration longitudinally within a cohort of 467 newly arrived adult refugees over the course of four years (overall participant retention was 70 per cent). The RISE instrument measured 10 ‘pathways’ to integration, as well as Overall Integration, based on Ager and Strang’s integration framework. Results show varying patterns of engagement with specific pathways over time, suggesting that members across the cohort deal with similar issues during different phases of integration. On average, the Overall Integration increased steadily over time. Men had statistically higher means than women each year on Overall Integration, although the rate of change between the two was the same. Statistical differences in rates of integration were observed by ethnicity and age. Overall Integration among refugees who were 55 years or older progressed significantly less than younger refugees. Approximately 5 per cent of the participating refugee cohort regressed to a lower level of integration each year. This study addressed a need for longitudinal research into refugee integration, using a valid and statistically reliable survey that can be adapted to other contexts worldwide.
