Abstract

There is an increasing awareness of the need to promote behaviors consistent with the understanding that individuals with dementia deserve adequate respect. Person-centered attitudes on the part of a care facility’s staff can affect care practices and relationships with residents. This study examined the psychometric properties of the Korean version of the Personhood in Dementia Questionnaire (KPDQ), which measures staff’s person-centered attitudes toward individuals with dementia. The KPDQ was translated and adapted based on commonly used guidelines from the World Health Organization. For psychometric testing, the data obtained from a total of 269 participants in 13 long-term care facilities were analyzed. Factor analysis, item fit, convergent validity, and known-group validity were examined. Reliability and differential item functioning (DIF) based on Rasch analysis were also assessed. The KPDQ consists of 20 items with three subscales (“agency”, “respect for personhood” and “psychosocial engagement”). Item fit statistics indicated that each item fits well with the underlying construct. The KPDQ demonstrated satisfactory convergent validity, known-group validity and internal consistency reliability. There was no DIF by subgroup according to age or educational status. Results indicated that the KPDQ is a reliable and valid tool for measuring long-term care staff’s beliefs about personhood.

Highlights

Increasing evidence indicates that person-centered care is an essential dimension of care for patients with dementia living in long-term care facilities [1]
To develop the KPDQ, we adapted the English version of the Personhood in Dementia Questionnaire (PDQ) and conducted Rasch analysis to examine internal consistency reliability, item fit and differential item functioning (DIF)
The results showed that the instrument reliably and validly measured the person-centered attitudes of staff working in Korean long-term care facilities

Summary

Introduction

Increasing evidence indicates that person-centered care is an essential dimension of care for patients with dementia living in long-term care facilities [1]. Person-centered care supports health by attending to the individual patient’s values and preferences [2] It focuses on improving quality of life by delivering individualized care based on the dignity of each human being [3]. 8) suggested person-centered care as the basis for dementia care and developed the concept of personhood in dementia care, defining it as “a standing or status that is bestowed upon one human being, by others, in the context of relationship and social being. Respect, and trust.” Person-centered care in long-term care settings has a beneficial effect on residents’ psychological well-being and behavioral symptoms, in addition to reducing the need for psychotropic medication [5]
