The domains and items of MeRS
A total of initial 112 items in the English language were generated from a literature review and these items were grouped into control, resourceful, growth, and involvement domains. During the research meeting, the items were reviewed by all researchers based on the TOP (trait, outcome, process) approach, and a consensus was reached for 89 items of MeRS 1.0 representing the four resilience domains. The final definition of the resilience domain and the total number of items representing each domain are summarized in Table 1. These items are rated against a four Likert scale; 1 (strongly disagree), 2 (disagree), 3 (agree), and 4 (strongly agree).

Content validity index
14 expert panels from various related specialties were invited for the content validation study. Six expert panels accepted the invitation and returned the completed content validation form. The expert panels comprised of two psychiatrists, two medical educationists, one clinical psychologist, and one community counselor.
The S-CVI score was 0.84. Out of 89 items, 36 were accepted without modification, 26 were rejected (I-CVI of less than 0.80), and 27 were reviewed by the researchers based on the expert panels' qualitative feedback. The researchers reached a consensus to revised 17 items and deleted 10 items due to, redundancy or ambiguity. This eventually created MeRS 2.0 with a total of 53 items.
Face validity index
18 medical officers were invited through mailing invitations. 10 medical officers participated in the face validation study. Based on the rating, the S-FVI was 0.82. 12 items with I-FVI of less than 0.80 were removed and MeRS 3.0 was created with a total of 41 items.
Internal Structure Assessment through Exploratory Factor Analysis
Out of 167 invited medical officers, 160 returned the questionnaires with a response rate of 95.8%. Most participants were 31 to 35 years old (75.6%), female (50.6%), Malay (68.1%), married (71.9%), were in medical-based specialties (54.4%), and had a clinical experience of more than five years (90.6%). The data was found to have a normal distribution, a significant Bartlett's test, and a Kaiser-Mayer-Olkin (KMO) value of 0.84, suggesting excellent sampling adequacy.
EFA was conducted on all 41 items using Principal Axis Factoring (PAF). Initial EFA analysis suggested a total of 12 factors may be extracted. Guided by the domain identification stage and the scree plot, only the first four factors with the highest eigenvalues were rotated. 37 items were found to have acceptable factor loadings from 0.407 to 0.764. Four items were removed due to factor loading was less than 0.40; ‘I never give up in any situation’, ‘I know my limit when working on challenging task’, ‘I find different ways to handle difficult situations’ and ‘I find it worth to do same things over again’.
As the items that load highly on factor 1 were related to the future state and internal conditions, factor 1 was named as the growth domain. The items that loaded on factor 2 all were influenced by the present state and internal conditions, hence named as the control domain. The items that loaded on factor 3 were influenced by the present state and external condition, hence labeled as the involvement domain. Finally, all four items that loaded on factor 4 were related to the ability to find appropriate solutions from available resources and named as the resourceful domain.
Reliability Analysis
The final 37 items were found to have a Cronbach’s coefficient alpha of 0.914 (scale level). The Cronbach’s coefficient alpha for the involvement domain was 0.719, the resourceful domain was 0.779, the control domain was 0.818, and the growth domain was 0.891.
Scoring of MeRS
Similar to other resilience instruments, a higher score of MeRS indicates a greater resilience and vice versa. There was no reverse scoring as there were no negative items. Three levels of resilience competency (exceptional, established, and developing) were established based on the highest 27% and the lowest 27% score respectively (29) as shown in Table 2.
