OBJECTIVES: Measuring poverty in health care settings may contribute to identifying patients in poverty and subsequently getting appropriate management. Although many scales are available to measure poverty in health, less attention has been paid to the poverty related quality of life. The purpose of this methodological study was to adapt the Poverty Related Quality of Life Questionnaire developed by Boyer and others (2014) into Turkish and to evaluate its psychometric properties for a Turkish patient population.  METHODS: The scale was adapted into Turkish through a translation and back-translation process. The content validity of the scale was assessed using expert approval. The psychometric properties of the scale were investigated by collecting data from 300 patients in 3 emergency departments from random selected hospitals in Ankara during the period of 1 April–30 May 2015.  RESULTS: An exploratory factor analysis identified that the seven-factor structure accounted for 80.1% of the total variance. A confirmatory factor analysis indicated a sufficient model fit for the construct validity of the scale:  root mean square error of approximation, 0.041; comparative fit index, 0.93; general fit index, 0.97; standardized root mean square residual, 0.050. Cronbach’s alpha for the total scale was 0.83 and each item achieved the 0.40 standard for item internal consistency. Significant associations with socioeconomic and clinical indicators showed good discriminant validity.  CONCLUSIONS: This study supports the validity and reliability of the Turkish version of Poverty Related Quality of Life Questionnaire. This instrument can be used to measure multiple aspects of poverty in the health care settings; however, as poverty and quality of life are  contextual facts, further work is needed to test the psychometric properties of this scale both in Turkish and different cultures.
