Abstract

Introduction: Quality of the Carer-Patient Relationship (QCPR) is a specific scale for testing the quality of relationships between the caregiver and the care recipient. Aims: The aim of the study was to translate, culturally adapt and validate the Polish language version of the QCPR questionnaire. Material and methods: The study was conducted in a group of 102 people who agreed to participate in this study. The group included 43 seniors with early and intermediate dementia and 59 carers of people with dementia. The snowball method was used in the selection of the sample. All respondents lived in the following provinces: Małopolskie and Śląskie. Respondents completed the paper version of the QCPR questionnaire once. The research was carried out in January 2020. Results: Cronbach's alpha reliability coefficients (α) for the Polish language version was α = 0.93α, which means that a very high level of internal compliance was noted. Conclusions: The proposed Polish language version of the Quality of the Carer-Patient Relationship (QCPR) questionnaire allow to assess the quality of relationships between people creates dyads. It should be noted that the analysis concerns a single-factor variant. The level of reliability of the top-down scales is admittedly high (warmth: α = 0.93; criticism: α = 0.75), nevertheless the analyzes show that it is a purely arbitrary, content division, and the responses of the respondents do not combine in the scales highlighted in the original version of the questionnaire.
