Abstract

Rationale, aims, and objectives: The aim of the study was to evaluate the reliability and validity of the Turkish version of the EmPHasis-10 questionnaire to ensure cultural adaptation.

Methods: This study involved translation, back translation, and cross-cultural adaptation. One hundred and one patients who were diagnosed as having pulmonary hypertension (PH) for at least 6 months were evaluated using the Turkish version of EmPHasis-10. Turkish version of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used as gold standard to assess the validation of the Turkish version of the EmPHasis-10 questionnaire. Relationship between MLHFQ and EmPHasis-10 was analysed using Spearman correlation analysis to assess the validation. Cronbach alpha (internal consistency) and exploratory factor analyses were used to assess the questionnaire's reliability.

Results: The statistical analysis showed that the EmPHasis-10 questionnaire showed a high validity with MLHFQ (r = 0.85) (P = 0.001). Reliability analysis showed that EmPHasis-10 had a high level of Cronbach alpha (α = 0.98) and internal consistency (ICC = 0.97).

Conclusions: The Turkish version of EmPHasis-10 is a quality of life questionnaire specific to PH. It has a high-level validity and reliability questionnaire that can be used by researchers and physicians.

Keywords: pulmonary hypertension; quality of life; reliability; validity.
