Cross-cultural adaptation and psychometric testing of the Quality of Dying and Death Questionnaire for the Spanish population

Psychometric Properties of the Brazilian Version of the Quality of Dying and Death for Adult Family Members of ICU Patients

Death is a complex, subjective phenomenon that requires an understanding of experiences to be qualified to provide care during the end-of-life process. This study aimed to analyze the psychometric properties of the Portuguese version (Brazil) of the Quality of Dying and Death (QODD) scale on family members of patients who died in adult intensive care units. A methodological study was conducted with 326 family members of patients that died in three ICUs of public hospitals in the state of São Paulo, Brazil. For this study, the QODD 3.2a (25 items and six domains) was administered during the period from December 2020 to March 2022. The analysis was performed using the classic theory of the tests and the goodness of fit of the model was tested using confirmatory factor analysis. We have used Spearman's correlation coefficients between the scores of the overall scale and domains. Cronbach's alpha coefficient and the intraclass correlation coefficient (ICC) were used for the evaluation of internal consistency and temporal stability, respectively. The Horn's parallel analysis indicated two factors that were not confirmed in the exploratory factor analysis. A single factor retained 18 of the initial 25 items and the analysis of the goodness of fit to the unidimensional model resulted in the following: CFI = 0.7545, TLI = 0.690, chi-squared = 767.33, df = 135, RMSEA = 0.121 with 90%CI, and p = 5.04409. The inter-item correlations indicated a predominance of weak correlations among the items of the instrument. The items with the largest number of moderate correlations were questions 13b, 9b, and 10b and a strong correlation was found between questions 15b and 16b. Cronbach's alpha coefficient was 0.8 and the ICC was 0.9. The Quality of Dying and Death-Version 3.2a (intensive therapy) in Brazilian Portuguese has a unidimensional structure and acceptable reliability. However, it did not obtain a good fit to the proposed factorial model.

Protocol for the development and multisite validation of the Quality of Dying and Death-Revised Global Version scale

INTRODUCTION

Evaluating the quality of dying and death is essential to ensure high-quality end-of-life care. The Quality of Dying and Death (QODD) scale is the best-validated measure of the construct, but many items are not relevant to participants, particularly in low-resource settings. The aim of this multisite cross-sectional study is to develop and validate the QODD-Revised Global Version (QODD-RGV), to enhance ease of completion and relevance in higher-resource and lower-resource settings.

METHODS AND ANALYSIS

This study will be a two-arm, multisite evaluation of the cultural relevance, reliability and validity of the QODD-RGV across four participating North American hospices and a palliative care site in Malawi, Africa. Bereaved caregivers and healthcare providers of patients who died at a participating North American hospice and bereaved caregivers of patients who died of cancer at the Malawian palliative care site will complete the QODD-RGV and validation measures. Cognitive interviews with subsets of North American and Malawian caregivers will assess the perceived relevance of the scale items. Psychometric evaluations will include internal consistency and convergent and concurrent validity.

ETHICS AND DISSEMINATION

The North American arm received approval from the University Health Network Research Ethics Board (21-5143) and the University of North Carolina Institutional Review Board (21-1172). Ethics approval for the Malawi arm is being obtained from the University of North Carolina Institutional Review Board and the Malawian National Health Science Research Committee. Study findings will be disseminated through publication in peer-reviewed journals and conference presentations.

Translation and Cultural Adaptation into Portuguese of the Quality of Dying and Death Scale for Family Members of Patients in Intensive Care Units

The translation and cultural adaptation of the Quality of Dying and Death in Brazil may provide a reliable and reproducible scale for collecting and analyzing data on the process of dying and death, given the absence of Brazilian studies that have produced or used scales in this topic. The purpose of this study was to perform the translation and cultural adaptation of the Quality of Dying and Death (QODD 3.2a) scale for intensive care patients' relatives into Portuguese (Brazil). This methodological study was carried out in a public university of the São Paulo State University (UNESP) medical school, São Paulo, Brazil, in three stages: translation and back-translation by two native-speaking independent professionals, analysis by a committee of specialists, and a pre-test phase. The final version was created by seven experts after making semantic, idiomatic, and cultural changes to 16 items. The results indicated a satisfactory content validation index (CVI ≥ 0.80). This version was applied on 32 relatives of patients who were hospitalized in a public hospital in the interior of São Paulo. No item was excluded from the instrument. The content and face validity were achieved to a satisfactory standard, in addition to reaching the minimum parameters recommended in the literature. The Portuguese version of QODD 3.2a for relatives of deceased patients in intensive care is appropriate and culturally adapted for use in Brazil.

Translation, Validity and Internal Consistency of the Quality of Dying and Death Questionnaire for Brazilian families of patients that died from cancer: a cross-sectional and methodological study

BACKGROUND

The Quality of Dying and Death Questionnaire (QoDD) may prove to be an important evaluation tool in the Brazilian context, and, therefore, can contribute to a more precise evaluation of the dying and death process, improving and guiding the end-of-life patient care.

OBJECTIVE

To translate and cross-culturally adapt the QoDD into Brazilian Portuguese and measure its validity (convergent and known-groups) and internal consistency.

DESIGN AND SETTING

A cross-sectional, methodological study was conducted at the Hospital de Câncer de Barretos, Brazil.

METHODS

A total of 78 family caregivers participated in this study. Semantic, cultural, and conceptual equivalences were evaluated using the content validity index. The construct validity was assessed through convergent validation and known groups analysis [presence of family members at the place of death; feel at peace with dying; and place of death (hospital versus home; hospital versus Palliative Care)]. Internal consistency was evaluated using Cronbach's alpha.

RESULTS

The questionnaire was translated into Brazilian Portuguese and presented evidence of a clear understanding of its content. Cronbach's alpha values were ≥ 0.70, except for the domains of treatment preference (α = 0.686) and general concerns (α = 0.599). The convergent validity confirmed a part of the previously hypothesized correlations between the Palliative Care Outcome Scale-Brazil (POS-Br) total scores and the QoDD domain scores. The QoDD-Br domains could distinguish the patients who died in palliative care and general wards.

CONCLUSION

The QoDD-Br is a culturally adapted valid instrument, and may be used to assess the quality of death of cancer patients.

Validation of the Quality of Dying and Death Questionnaire among the Chinese populations

OBJECTIVE

This study reports the evaluation of the original 31-item Quality of Dying and Death Questionnaire (QODD) using a sample of caregivers of recently deceased older adults in China, and the validation of a shortened version (QODD-C) derived from the original scale.

METHODS

The translation was performed using a forward and back method. The full scale was tested with 212 caregivers of decedents in four regions of China. Confirmatory factor analysis tested the model fit between the full Chinese version and the original conceptual model and generated the QODD-C. The psychometric analysis was performed to evaluate the QODD-C's internal consistency, content validity, construct validity, and discriminant validity.

RESULTS

A five-domain, 18-item QODD-C was identified with excellent internal consistency reliability (Cronbach's α = 0.933; split-half Pearson's value = 0.855). The QODD-C total score was significantly associated with constructs related to five domains. The caregiver's relationship with the decedent, the decedent's age at death, death reason, and death place was significantly associated with the QODD-C total score.

SIGNIFICANCE OF RESULTS

The QODD-C is a valid and reliable instrument for assessing the quality of dying and death among the Chinese populations.

Validation of the Chinese Version of the Quality of Dying and Death Questionnaire for Family Members of ICU Patients

CONTEXT

The quality of end-of-life care services directly affects the end-of-life quality of life of patients and their families. At present, there are no standard tools in China for assessing the quality of dying and death (QODD) of critical intensive care unit (ICU) patients.

OBJECTIVES

This study aimed to introduce the Chinese version of the QODD questionnaire for family members of ICU patients, after transcultural adaptation and validation, to provide an effective instrument for assessing the quality of end-of-life care of ICU patients in China, fill the gap in the evaluation of the quality of end-of-life care of critical ICU patients in China, and offer a theoretical basis and practical guidance during purposeful intervention.

METHODS

This study involved the main adult caregivers or principal family members of 149 dying critically ill patients. The original QODD scale was translated using the double forward and backward method. Nine cultural adaptation experts adapted the Chinese version of the QODD scale for completion by family members of ICU patients. Then, we carried out content validity, structural validity, internal consistency, confirmatory factors, and item correlation analysis of the modified scale.

RESULTS

The Chinese version of the QODD for family members of ICU patients was developed after some items were deleted or modified. The content validity index was 0.93, indicating that all items were correlated with the measurement of death quality. The Kaiser-Meyer-Olkin value was 0.797, suggesting that the correlations between items were high. The Cronbach's α was 0.865, indicating good internal consistency. In confirmatory factor analysis, the fit indices were χ² = 207.327, non-normed fit index = 0.916, root mean square error of approximation = 0.033, and comparative fit index = 0.93, indicating a good fit of the five-factor model of the Chinese version of the QODD questionnaire for family members of ICU patients.

CONCLUSION

The Chinese version of the QODD questionnaire for family members of ICU patients is a reliable and effective instrument for evaluating the quality of death among patients who die in the ICU and can be applied to clinical practice and research.

Psychometric Testing of the Spanish Modified Version of the Mini-Suffering State Examination

Background: The mini-suffering state examination is a valid and reliable measure that have been used to assess suffering in patients with advanced cancer. The aim of this study was to carry out a psychometric analysis of the Spanish version of the mini-suffering state examination. Method: A validation study was conducted. Seventy-two informal caregivers of deceased patients in palliative care were included in this study. A psychometric testing of content validity, internal consistency, and convergent validity with the Spanish version of the quality of dying and death questionnaire was performed. Results: The original instrument was modified to be used by informal caregivers. The content validity was acceptable (0.96), and the internal consistency was moderate (α = 0.67). Convergent validity was demonstrated (r = −0.64). Conclusion: The Spanish modified version of the MSSE showed satisfactory measurement properties. The Spanish modified version of MSSE can be useful to facilitate screening, monitor progress, and guide treatment decisions in end-of-life cancer patients.

The Quality of Dying and Death of Advanced Cancer Patients in Palliative Care and Its Association With Place of Death and Quality of Care

The quality of dying and death is currently considered an objective to achieve at the end of life. The aim of this study is to analyze the quality of dying and death of advanced cancer patients in palliative care and its association with place of death and quality of care from the perspective of family caregivers. This is a cross-sectional study. The study sample included 72 family caregivers of advanced cancer patients in palliative care. For the evaluation of the quality of dying and death, the Spanish version of the Quality of Dying and Death Questionnaire was used. Quality of care was evaluated with the Palliative Care Outcome Scale. The mean (SD) total score on the Spanish version of the Quality of Dying and Death Questionnaire was 64.56 (20.97). The quality of dying and death was higher when the patients died at home, 70.45 (19.70), and it was positively correlated with quality of care (r = 0.61). Palliative care contributes to achieving a satisfactory quality of dying and death in Spanish advanced cancer patients. Further studies that evaluate interventions for improving the quality of dying and death in the advanced cancer population are needed.

Translation, Cultural, and Age-Related Adaptation and Psychometric Properties of Persian Version of "Quality of Dying and Death" in Nurses Working in Neonatal Intensive Care Units

Background:

Death and dying care is an area with less attention in nursing. This even is evidenced as more challenging in some populations such as neonates. Neonatal intensive care unit (NICU) nurses should be aware of the quality of care they provide for dying neonates and their families to find the areas which need attention.

Objective:

The aim of this study was to assess the psychometric features of the Quality of Dying and Death (QODD) questionnaire in NICU nurses in Tehran, the capital city of Iran.

Methods:

This methodological study was conducted in 2017. For this purpose, using census method, 130 NICU nurses working in selected hospitals participated. After the backward–forward translation, based on the method proposed by the International Test Commission, the psychometric properties of the Persian QODD were examined through the assessment of the face, content and construct validity, internal consistency, and stability.

Results:

Final Persian QODD's content and face validity were accepted through a qualitative method. In the confirmatory factor analysis, the original version of QODD was not confirmed. Subsequently, an exploratory factor analysis was carried out in which phrases were included in three dimensions (symptom control, preparation for death of neonate, and professional attention) that explained 75% of the variance. Cronbach's alpha values ranged from 0.82 to 0.88 for these three dimensions. The intraclass correlation coefficient (ICC) was ICC = 0.94 between two tests performed with a 2-week interval on twenty eligible nurses.

Conclusions:

The Persian version of QODD has acceptable psychometric properties in nurses working with the neonatal population and can be used to investigate the NICU nurses' opinion on the QODD provided in NICU patients.
