Cross-cultural adaptation and psychometric properties of the Herth Hope Index in Kinyarwanda: adapting a positive psychosocial tool for healthcare recipients and providers in the Rwandan setting

Abstract

Background: The lack of culturally appropriate instruments to measure hope across cultural settings is a barrier to assessing and addressing the relationship between hope and health outcomes. The study aim was to adapt and evaluate the psychometric properties of the Herth Hope Index (HHI) in Kinyarwanda in a population of healthcare recipients and healthcare workers in Rwanda. Methods: A transcultural translation and adaptation of the HHI was conducted using qualitative methods (n = 43) to achieve semantic, content, and technical equivalence. The adapted instrument was administered to a purposive sample (n = 206) of Rwandan healthcare patients and providers. Temporal reliability, internal reliability using Cronbach's alpha, and construct validity using confirmatory factor analysis (CFA) were assessed. Results: The Herth Hope Index-Kinyarwanda (HHI-K) was found to have strong internal consistency (α = 0.85) and test-retest reliability (r = 0.85). The original HHI three-factor structure fit the data well in CFA (normed chi-square = 1.53; root mean square error of approximation = 0.05; standardized root mean square residual = 0.05; comparative fit index = 0.96; Tucker-Lewis Index = 0.95). Conclusion: This article presents the first rigorous cultural adaptation of the HHI in a low-income country. The HHI-K has acceptable psychometric properties, resulting in a new useful tool for research, program development, and evaluation in Rwandan healthcare settings. The HHI-K instrument can be used to assess the effectiveness of programs that aim to promote hope and health outcomes across health system-and individual-levels. The process also provides a feasible model for adaptation of a positive psychosocial tool for both patients and providers in lowresource settings.

Study on the Effect of Hope Theory Combined with Psychological Intervention on the Improvement of Prognosis

“…In general, patients can improve their negative psychology to a certain extent by giving short-term rehabilitation guidance. However, lack of a personalized nursing plan will make the later treatment effects of patients not ideal [ 3 ]. Hope is a subjective, abstract, and complex multidimensional concept.…”
