Translation, Cross-Cultural Adaptation, and Psychometric Analysis of the Attitudes Towards Homelessness Inventory for Use in Sweden.

BACKGROUND

Homelessness is an increasing problem worldwide, and the origins of homelessness in high-income countries are multifaceted. Due to stigma and discrimination, persons in homelessness delay seeking health care, resulting in avoidable illness and death. The Attitudes Towards Homelessness Inventory (ATHI) was developed to cover multiple dimensions of attitudes toward persons in homelessness and to detect changes in multiple segments of populations. It has, however, not previously been translated to Swedish.

AIMS

The aim of the present study was to translate, cross-culturally adapt, and psychometrically test the ATHI for use in a Swedish healthcare context.

METHODS

The project used a traditional forward- and back-translation process in six stages: (1) two simultaneous translations by bilingual experts; (2) expert review committee synthesis; (3) blind back-translation; (4) expert review committee deliberations; (5) pre-testing with cognitive interviews including registered nurses (n = 5), nursing students (n = 5), and women in homelessness (n = 5); and (6) psychometric evaluations. The final ATHI questionnaire was answered by 228 registered nurses and nursing students in the year 2019.

RESULTS

The translation process was systematically conducted and entailed discussions regarding semantic, idiomatic, experiential, and conceptual equivalence. Confirmatory factor analysis was used to examine if the collected data fitted the hypothesized four-factor structure of the ATHI. Overall, it was found that the model had an acceptable fit and that the Swedish version of ATHI may be used in a Swedish healthcare context.

LINKING EVIDENCE TO ACTION

The ATHI has been shown to be a psychometrically acceptable research instrument for use in a Swedish healthcare context. The systematic and rigorous process applied in this study, including experts with diverse competencies in translation proceedings and testing, improved the reliability and validity of the final Swedish version of the ATHI. The instrument may be used to investigate attitudes toward women in homelessness among nursing students and RNs in Sweden.
