Validation of the psychometric properties of the Malay advance care planning questionnaire

Abstract

Background There is a growing interest among the developing countries on advance care planning (ACP) due to the reported benefits of planning ahead in the developed countries. Validated instruments in various languages have been developed to facilitate study on the views of public prior to its implementation. However, instrument to explore the views on ACP in Malay has not been developed and validated yet, even though Malay is spoken extensively by approximately 220 million people in the Malay Archipelago. There is also a need for instrument in Malay language to facilitate the assessment of knowledge, attitude and practice (KAP) of Malaysians regarding ACP. Therefore, the aim of this study was to validate the psychometric properties of the Malay Advance Care Planning Questionnaire (ACPQ-M). Methods The ACPQ was translated according to international guidelines. This validation study was conducted from January to June 2018. Participants who were ≥ 21 years old, and able to understand Malay were recruited from an urban primary care clinic and a tertiary education institution in Malaysia. A researcher administered the ACPQ-M to participants via a face-to-face interview at baseline and 2 weeks later. Each interview took approximately 10–20 min. Results A total of 222/232 participants agreed to participate (response rate = 96.0%). Exploratory factor analysis and confirmatory factor analysis found that the ACPQ-M was a 4-factor model. The Cronbach’s α values for the four domains ranged from 0.674–0.947. Only 157/222 participants completed the test-retest (response rate = 71%). At test-retest, quadratic weighted kappa values for all domains ranged from 0.340–0.674, except for two domains which ranged from − 0.200-0.467. Conclusions The ACPQ-M was found to be a 4-factor model, and a valid and reliable instrument to assess the KAP regarding ACP. This instrument can contribute to profound understanding of the KAP of Malaysians regarding ACP, and assist policy makers in determining the readiness for legislation of ACP in Malaysia.

Psychometric properties of Persian Version of Advance Care Planning Questionnaire among Older Adults in Iran

“…The original study performed in Malaysia had not performed con rmatory validity (25). However, similarly the study by Lim et al has also con rmed the four-dimensional model of this instrument (45). Thus, considering the con rmation of the four dimensions of the model in the present study as well as the original study together with its con rmation in the study by Lim et al, it seems that the four-dimensional model is also suitable in Persian language.…”

Psychometric properties of Persian version of advance care planning questionnaire among older adults in Iran

“…In the study by Lim et al, the translation was performed as back-and-forth, and the English questionnaire was translated to Malaysian. Next, the face and content validity were confirmed by a specialist panel consisting of two first aid physicians, three pharmacists, and one pharmacist currently involved in the field of ACP in Malaysia [ 47 ].…”

“…In the dimension of “justifications for advance care planning”, there was no change in the Persian version of the tool according to the Malaysian version [ 53 ]. According to the results of this study, this dimension was not changed in the Malay version [ 47 ].…”

“…In line with this study, in the research by Lim et al, again KMO in all dimensions was above 0.6 and the factor loading values were also above 0.4. Furthermore, they reported suitable exploratory factor analysis for the ACPQ [ 47 ]. We are not able to compare the study results with more studies since only one study has dealt with translation and psychometric properties determination of this study.…”

Development and validation of the advance care planning practice preference scale for clinical nurses

“…Therefore, the evaluation of ACP practice preference is of great significance for developing targeted ACP interventions among clinical nurses and updating their professional roles to improve nurse‐led ACP practice. Currently, relevant assessment instruments are mainly focused on patients and surrogate decision makers (Lasmarías et al, 2021; Lim et al, 2021; Van Scoy et al, 2019), and there is a lack of quantifiable instruments to measure ACP practice preference for clinical nurses.…”
