Abstract
Background:
Religious health fatalism belief that health outcome is only determined by God without seeking treatment. Tools are needed to measure fatalism among patients with chronic disease, especially diabetic foot ulcer (DFU) patients. The aim of this study was to conduct psychometric test of religious health fatalism questionnaire (RHFQ) including translation, validation, reliability, and cut-off point among DFU out-patients.
Design and methods:
This study employed cross sectional design, using self-report questionnaire. Data were collected from diabetes clinic in five hospitals, Indonesia. The inclusion criteria were patients who had history of DFU more than 2 years. Total sample in this study was 184 patients. This study was conducted from April to June 2021. Permission to use the RHFQ was permitted by the original author. We conducted translation and adaptation questionnaire to Bahasa. We employed reliability test with internal consistency, construct validity, and convergent validity. Construct validity was evaluated using exploratory factor analysis (EFA). Cut-off point RHS was analyzed using receiver operating characteristic (ROC). ROC was evaluated using correlation score between total score RHFQ and CDRISC-25 Indonesia version. Previous study mentioned that resilience is a predictor of religious. The Cronbach’s alpha for RHFQ Indonesia version was adequate.
Results:
EFA showed adequate with Kaiser–Meyer-Olkin (KMO) value of 0.72 and the Bartlett’s test of sphericity was significant. According to ROC curve analysis, the cut-off point at a score 67.5 indicated the best sensitivity and specificity.
Conclusions:
RHFQ Indonesia version had reliability and validity for screening religious health fatalism among DFU outpatients.
Introduction
Diabetic foot ulcer (DFU) is potentially complication of diabetes, and it can be life threating. 1 The burden of DFU patients very high, such as more frequent to visit hospital as well as most commonly admitted at hospital compare with diabetic patients without foot ulcer. 2 These conditions will increase the economic expenditure 3 as well as mental health problems such as depression 4 and anxiety among DFU patients. 5 Depression and anxiety will decrease self-adherence among DFU patients and increase morbidity and mortality.6,7
Religious beliefs affect health behavior. It has significant impact on self-adherence, especially among patients with chronic diseases 8 such as diabetes. 9 Individuals who have religious health fatalism tends to give up easily. Fatalism is negatively correlated with self-adherence and positively correlated with seeking treatment 10 and belief that health outcome is only determined by God without seeking treatment. 11 Health education and health promotion for individual with religious health fatalism is needed. So it was required tool to understand this fatalism.
Tools are needed to measure religious health fatalism and screen fatalism among patients with chronic disease, 12 especially among DFU patients. This tool can be used for public health strategies, to prevent fatalism and increase self-adherence. 13 Several tools have been created to assess fatalism among patients with chronic diseases such as the Powe ism Inventory for cancer patients 14 and also fatalism scale with dimension of predetermination, luck, and pessimism. 15 In addition, the religious health fatalism questionnaire (RHFQ) was widely used to determine health fatalism related health behaviors. RHFQ had good validity and reliability. 11 RHFQ has never been translated into Bahasa and based on our knowledge, no study has been conducted to evaluate the psychometric test. So, the aim of this study was to conduct psychometric test of RHFQ, including translation, validation, reliability, and cut off point among diabetic foot ulcer (DFU) out-patients.
Methods
Participants and setting
This study employed cross sectional design, using self-report questionnaire through Google-Form. Data were collected from outpatients from diabetes clinic in five hospitals, South Kalimantan, Indonesia. The inclusion criteria were patients who had history diabetic foot ulcer (DFU) more than 2 years based on Wagner Scale, aged 18–75 years old. The exclusion criteria was patients disagreed to participate in this study. Total sample in this study was 184 patient and RHFQ had 17 parameters. It was recommended to include 5–20 observations for each parameter. The minimum sample that we need in this study was 85. 16
Instruments
Resilience (CD RISC-25)
Resilience was measured using Connor-Davidson Resilience Scale-25 (CD RISC-25) Indonesian version. 17 We already granted from original author CD RISC 25 consist of 25 items and 7 domains, including hardiness (items 5, 10, 11, 12, 22, 23, 24), coping (items 2, 7, 13, 15, 18), adaptability/flexibility (items 1, 4, 8), meaningfulness/purpose (items 3, 9, 20, 21), optimism (items 6, 16), regulation of emotion and cognition (items 14, 19), and self-efficacy (items 17, 25). Higher score indicates higher resilience, and lower score indicates that individual tends to depress, anxious, and post-traumatic stress disorder. This original questionnaire had good convergent validity and adequate reliability with Cronbach alpha 0.902. 18
Religious health fatalism questionnaire (RHFQ)
Religious was measured using religious health fatalism questionnaire (RHFQ) created by Franklin et al. We already get permission to use this questionnaire. This questionnaire was used to assess health fatalism and preventive health behavior. It is 17-item test and consist of three dimensions: (1) Belief that God will provide good health (Item number 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11) was used to measure individual belief that God will provide health, (2) The destined plan (items 12, 13, 14, and 15) was used to measure that health was determined by God, (3) Helpless inevitability (items 16 and 17) was used to assess about individual had no control over one’s own health. This scale was used Likert scale from 1 = strongly disagree to 5 = strongly agree. Total score between 17 and 85. Higher score indicates fatalism. The original RHF has acceptable validity and reliability. 11

Procedures
This study was conducted from April to June 2021. Permission to use the RHFQ and CD RISC 25 Indonesia version was permitted by the original author. We conducted translation and adaptation English questionnaire to bahasa based on previous studies.13,19 The initial step was forward translation from original version into Bahasa; expert panel to review the result of translation, namely two expert panel who have expertise in nursing and psychology reviewed after translation into Bahasa, then we conducted back translation from bahasa to English and compare the result with the original one, and the last we conducted pilot study to 50 DFU Patients to examine whether the Bahasa questionnaire was understood by them. In the end, we tested final version of questionnaire to assess psychometric test using google form. The researcher asked the hospitals for permission to conduct this study. After getting permission, the researcher explained the study and asked the informed consent to participate in the study. The participants were allowed to withdraw from the study. Only the researchers who can access the answer of participants.
Statistical analyze
All analyze used SPSS (version 22) for windows. Descriptive statistics were computed to evaluate minimum and maximum value, mean and standard deviation (SD). Inter-item correlation and item-total correlation was calculated using Pearson correlation; correlation more than 0.2 means satisfactory. 16 We employed reliability test with internal consistency, the cronbach alpha more than 0.5 was considered reliable.20,21 Validity tests in this study were construct validity and convergent validity. Construct validity was evaluated using exploratory factor analysis (EFA), with principal components extraction and varimax rotation, using Kaiser–Meyer–Olkin (KMO) and Bartlett’s test of sphericity indicators. 22 KMO value must greater than 0.5 and Bartlett’s test of sphericity must be significant (p < 0.001).23,24
Confirmatory factor analysis (CFA) was used to evaluate the structural model fit of RHFQ. Goodness of fit was tested using AMOS software and it was evaluated using goodness of fit index (GFI), adjusted goodness-of-fit index (AGFI), normed fit index (NFI) >0.925 and root-mean-square error of approximation (RMSEA) ≤0.10. 26 Convergent validity was evaluated using factor loading, average variance extracted (AVE) and composite reliability (CR). Factor loading >0.32, 27 composite reliability (CR) >0.7028 meanwhile average variance extracted (AVE) >0.50; or AVE > 0.40 if CR>0.60. 29 Cut-off point RHS was analyzed using ROC (receiver operating characteristic). ROC was evaluated using correlation score between total score RHFQ and CDRISC-25. Previous study mentioned that resilience is a predictor of religious. 30

Discussion
The aim of this study was to conduct psychometric test of RHFQ, including translation, validation, reliability, and cut off point among Diabetic Foot Ulcer (DFU) out-patients. The results showed that RHFQ Indonesia was a stable instrument to measure religious health fatalism and similar with original RHFQ. 11
Reliability
Cronbach alpha of RHFQ Indonesia version was 0.707. The result showed that RHFQ Indonesia version had acceptable internal consistency and similar with original RHFQ, 11 it was 0.79. Previous study from Turkey showed that the cronbach alpha for RHFQ was 0.93. 31 However previous studies recommended that cronbach’s alpha >0.5 was considered reliable.20,21
Construct validity and convergent validity
RHFQ Indonesia version was supported by construct validity. Exploratory factor analysis was used to extract 17 items of RHFQ. Compare with the original RHFQ, the results of this study showed that some changes in the factor structure, however, all items was supported by factor loading more than 0.32. 27
The first factor of RHFQ original version consists of items 1–11. While the Indonesian version, the first factor consists of items 1–9. The second factor of RHFQ original version, consists of four items (item 12, 13, 14, and 15). While the Indonesian version has five items (item 12, 13, 14, and 15) with additional item 16. The third factor for the original version, consists of item 16 and 17. While the Indonesian version had three items (item 10, 11, and 17). Items in each factor of the RHFQ Indonesia version similar with original version. However, there were some changes in three items, such as item 10: I trust God not man, to heal me, item 11: if person has enough faith, healing will occur, healing will occur without doctor to do anything. Both of items were included in Helpless inevitability dimension. This condition may occur because the characteristic of respondent of DFU patients that often visit health services. They also feel worry due to the complications 5 or the risk of amputation. 32 This situation makes them helpless and only trust their condition to God.
We also conducted confirmatory factor analysis (CFA) to assess construct validity from RHFQ Indonesia version. Structure model of RHFQ Indonesia version was measured using indices, especially RMSEA. RMSEA was used to evaluate model and it was recommended ≤0.1. 26 This RHFQ had adequate model with factor loading more than 0.32 (Figure 1).
Receiver operating characteristic (ROC)
Receiver operating characteristic curve showed that RHF has a cut-off point of 67 (Figure 2). This is the first study to determine religious health fatalism scores in DFU patients. Previous studies showed that the higher score indicates the more fatalism. This study showed that score ≥67 means high fatalism or they believe that God control health.11,31 This situation must also be interpreted carefully according to the culture of each country 33 because most of participants were Muslim (Islam), so they believe that God control everything, However, Islam still emphasize to make effort in everything as well before giving up to God. 34
This study had limitation, such as the heterogeneous sample in length of suffering DFU and the age of participants, and thus, length of suffering DFU had effect on anxiety and how to control their health. However this study showed that RHFQ Indonesia version was valid and reliable to measure Religious health fatalism.

Significance for public health
Religious health fatalism affect health behavior. Religious health fatalism belief that health outcome is only determined by God without seeking treatment. Tools are needed to measure religious health fatalism and screen fatalism among patients with chronic disease, especially diabetic foot ulcer (DFU) patients. Tools are needed to measure religious health fatalism and screen fatalism among patients with chronic disease. This tool can be used for public health strategies, to prevent fatalism and increase self-adherence. This study, therefore, aims to evaluate psychometric properties of Religious health fatalism questionnaire (RHFQ) including translation, validation, reliability, and cut off point among DFU out-patients. So it can be used to screen health fatalism and to prevent it.
