Study type
Interventional
Description of intervention(s) / exposure
The content of the intervention module will mainly be adapted from “Partner to Improve Diabetes Education” (PRIDE) (permission has been granted from the owner from Vanderbilt University). However, this module will be tailored to the needs of the community, cultural sensitivity, diet and diabetic treatment of Malaysian people specifically in a rural area. The module content focus was based on Social Cognitive Theory approach as its theoretical framework. The intervention education will be held for about one month. The intervention session will be in a group format, coordinate and facilitate by the trained (diabetic education) post-graduate students who are not part of the research team at the selected health clinics. The intervention language will be in Bahasa Malaysia The intervention will focus on empowerment of respondents to change their lifestyle, behaviour and glycaemic control by improving their health literacy on Type 2 Diabetes Mellitus based on the adapted “Partner to Improve Diabetes Education” (PRIDE) module.
This intervention will incorporate general information about diabetes, diabetes nutrition information, diabetes medication treatment, lifestyle management, behaviour changes and foot care. In addition, the participants also will be given Malaysia Healthy Plate (quarter-quarter half) and diabetes self-management flip chart as take-home materials for their own references. The take-home material (flip chart) will be printed in Bahasa Malaysia.
All intervention sessions will be conducted in a group of 6-8 respondents at a private room in a health clinic and will be conducted by one trained (diabetic education) post-graduate students. In a group, the trained postgraduate will explain about the diabetes self-management and open a conversation with the respondents for discussion.
The whole intervention process would take about half-day (4 hours) for each respondent consists of 2 sessions, each session will take about 2 hours. Food and beverages will be provided to minimized discomfort to the respondents.
Session 1 (2 hours) consists of:-
1) general information about diabetes
2) diabetes nutrition information
3) diabetes medication treatment
Session 2 (2 hours) consists of:-
1) lifestyle management
2) behaviour changes
3) foot care
For this research, I will be teaching the module with the help of trained (diabetic education) post-graduate students. No treatment will be given to the respondents except they will continue with their own medication.
For the followup sessions, it will be held in 2 times:-
1) After 3 months of intervention
- Assessing respondent knowledge by using the same questionnaire at baseline.
- Take respondent latest HbA1c reading.
2) After 6 months post-baseline
- Assessing respondent knowledge by using the same questionnaire at baseline.
- Take respondent latest HbA1c reading.
For the duration of the followup session, it may take about 40 minutes - 1 hour for each participant.

Comparator / control treatment
The control group will continue their diabetic education receive from diabetic health clinic at Tanjong Karang Health Clinic. The module used is based on the Ministry of Health Malaysia. The session will consist of diet, medication adherence and exercise. It will be delivered verbally in Bahasa Malaysia. No take-home material or booklet will be given. The teaching session will be held at Tanjong Karang Health Clinic. It will be 2 hours session for every two weeks in a month. The respondents are selected from their diabetic patient's list from the health clinic.

Statistical methods / analysis
The formula for calculating sample size in hypothesis testing by comparing means was used (Lwanga, Lemeshow, & Organization, 1991). Two population mean formula is used due to comparing two groups for hypothesis testing. This is based on a patient's HbA1c level difference pre and post-intervention between control and intervention group with a response rate of 90%
Where,
N = Sample size
2s2 = estimated standard deviation (assumed to be equal for each group) is 16.7
??1 - a/2 = Z statistics for level of 95% confidence = 1.96
??1 – ß = Z statistics for 80% power =0.842
µ1 = estimated mean HbA1c reading after the intervention is 72.88 (Protheroe et al., 2016)
µ2 = estimated mean HbA1c reading for the control group is 66.19 (Protheroe et al., 2016)
By substituting the values using the above formula, we can have the calculation sequence as follows:
N = 2(16.7)2 [1.96+0.842]2 / (72.88 – 66.19)2
= 558.44 [7.851204] / 44.75
= 4384.42 / 44.75
N = 97.9 ˜ 98
Based on the above formula, the required minimum sample size for each group, n is 98.
After adjusting for 20% of non-response rate
N = 98 / 0.8
= 122.5 ˜ 123 particpants (for 1 group)
Participants in intervention group =123
Participants in control group = 123
TOTAL participants overall study = 246

Statistical analysis:-
Statistical analysis will be performed using IBM Statistical Package for Social Science (SPSS) for windows version 23.0. The purpose of these analyses is to answer all the research questions (HbA1c level, health literacy, quality of life, physical activity, knowledge and self-efficacy constructs of social cognitive theory). The level of significance for all statistical test will be set at alpha less than 0.05. Odds numbers will be allocated for the intervention group, so they represent the responses and score of participants in the intervention group, whereas even number will be allocated for the control group, as they represent the responses and scores of participants in the control group.
The researcher will verify the accuracy of data entry with the help of a professional statistician. Descriptive and inferential analyses will be analysed in this research.
Descriptive results will be presented as:-
1)mean
2)median
3)frequency
4)percentage
Inferential statistics will be utilized where appropriate
The confidence interval will be set at 95% for the estimation mean. The level of significance will be set at p less than 0.05. To access comparability of the intervention and control during baseline, Chi-square will be used in categorical data whereas independent T-test will be used in continuous data.
Data analysis will be done in different stage. within-subject analysis and between-subject analyses. A repeated measure ANOVA will be used to compare the difference between and within the intervention group and control group from baseline to post-intervention. Multivariate analysis of covariance (MANCOVA) will be used to compare the difference between and within intervention group and control group from baseline to post-intervention after controlling for covariates sociodemographic characteristics (age, gender, ethnic and marital status), socioeconomic characteristics (income status, education background and occupation) and medical profiles (types of medication and duration of having Type 2 Diabetes Mellitus).
