| Issue/Objective | Robust measurement of implementation outcomes is central to translating evidence into equitable health impact, particularly in humanitarian contexts where intervention uptake, fidelity, and sustainability are highly context dependent. Despite widespread use, the psychometric performance of the Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), and Feasibility of Intervention Measure (FIM) has not been adequately evaluated among conflict-displaced populations. This study assessed the reliability, dimensionality, and construct validity of these measures among internally displaced persons (IDPs) in Nigeria to strengthen implementation accountability and evidence translation. |
|---|---|
| Methodology/Approach | Data were drawn from the baseline of the RESETTLE-IDP cluster randomized trial conducted in two IDP camps (Durumi and Wassa) in Abuja, Nigeria. A total of 224 participants completed all 12 AIM, IAM, and FIM items. Psychometric evaluation included internal consistency (Cronbach's α and composite reliability), exploratory factor analysis with parallel analysis, confirmatory factor analysis (CFA), average variance extracted, and heterotrait-monotrait ratios. Distributional properties, including ceiling effects, were assessed. Non-parametric tests examined associations with sociodemographic characteristics, and Spearman correlations assessed relationships with well-being and resilience. |
| Results | Internal consistency was acceptable to good across scales (α = 0.77-0.86), indicating adequate inter-item reliability. CFA demonstrated acceptable fit (CFI = 0.957; RMSEA = 0.077), but latent factor correlations were high (r = 0.82-0.92), and heterotrait-monotrait ratios exceeded 0.85, indicating limited discriminant validity. Mean scores were elevated (AIM = 4.72; IAM = 4.71; FIM = 4.60), with 51-55% of respondents at maximum values. Feasibility scores were significantly lower than acceptability and appropriateness (p < 0.05). Camp site was the only significant correlate (p < 0.05). |
| Discussion/Conclusion | Findings indicate acceptable reliability but limited construct discriminability. Feasibility may provide greater sensitivity to contextual constraints. Refinement and contextual adaptation of implementation measures are essential to improve accountability and ensure interventions are implementable and scalable in humanitarian settings. |
