Efficacy
Statistical methods / analysis
This is a feasibility study to determine safety, cultural appropriateness and to explore and trends in efficacy for people post mild TBI and so no formal sample size calculation was conducted.
Quantitative Analyses: Descriptive data on the time in weeks between referral, pre-intervention assessment, commencement of the intervention, consent rate and timeframe of the intervention sessions will be provided. Chi square tests or Fisher’s Exact tests (where relevant) will be used to determine if there are any differences in the proportion of participants completing all intervention sessions between the two groups and consent and attrition rates of eligible Maori and Pasifika participants compared to Europeans. The numbers of participants meeting the eligibility criteria recruited per month will be recorded and total time taken to meet the recruitment target for this feasibility study will be calculated. An effect size for the full trial will be estimated based on group comparisons controlling for baseline scores to refine the power calculation for the main trial and determine the necessary sample size to ensure statistical power of the main trial.

Qualitative Analysis: Following completion of the intervention, a qualitative interview will explore participant’s experiences of the intervention, their understanding of the approach and its techniques, aspects of the intervention that were helpful or unhelpful and any changes they feel would be beneficial. Participants will be asked about the relevance of the intervention and techniques to them and whether they felt the intervention was responsive to their culture. The qualitative analysis will identify whether further modifications to the programmes or study procedures are needed. Qualitative data will be analysed using the qualitative descriptive approach to identify how the intervention helped or hindered participants recovery. The qualitative data will be used to augment the interpretation of the quantitative analysis
