The survey was conducted from October 16, 2023, to November 16, 2023. There were 303 participants in all. The survey had a 100% response rate. Of the total, 123 (40.6%) were men and 180 (59.4%) were females. Their ages ranged from 18 to 94 years old, with a mean of 55.9±12.9 years. The male age, 57.4 ± 12.8 years, did not differ significantly from female age, 54.9 ± 12.9 years (t-value, 1.590 and P, 0.113). The duration of diabetes ranged from 1 to 40 years, with a mean of 9.1± 6.9 years. There is only one patient under the age of fourteen. Seven (2.3%) of the 303 patients were under 25, 107 (35.3%) were between the ages of 25 and 50, and 189 (62.4%) were beyond 50.
About 2.3% of the study group consisted of pregnant patients with gestational diabetes, while type 2 diabetes afflicted the majority of participants (n = 287; 94.7%). Nine (3%) of the 303 people did not know what kind of diabetes they had. Most participants (87.1%) believe that speaking with a medical professional is the best way to learn about diabetes. For 15 (5%) of all patients, social media was thought to be the best way to proceed and 18 (5.9%) think that the best sources of information regarding diabetes are social media and medical professionals. Out of the 303 participants, 6 (2%) believe that diabetes awareness events, brochures, and posters are suitable means of educating people about diabetes. Table-1 illustrates the frequency distribution of the participants' responses to 15-item Likert scale that ranged from strongly agree to strongly disagree,

3.1 Reliability of the questionnaire: Cronbach's alpha is most commonly used to quantify internal consistency (also known as "reliability"). The Likert scale we used had a high degree of internal consistency, with a Cronbach's alpha of 0.832 for the 15 items. After removing the statements (n= 5) that result in a greater Cronbach's alpha if deleted, the final Cronbach's alpha increased to 0.900. The Cronbach's Alpha item-total statistics for the final 10 item Likert scale are displayed in Table 2.

Forty of the 303 participants took the test (survey) again, and the total Likert scores of those individuals (60.2± 4.9) were compared using Pearson's Correlation to see if there was any correlation with their results from the initial measurement (60.2± 4.7). The two measurements showed an extremely significant association (r, 0.864; P, 0.000). Thus, the survey's test-retest reliability is excellent, we might conclude. This indicates that the study group was able to memorize it with ease. The regression line between the two measurements is shown in Figure 1. the figure shows a highly significant linear association between the two measurements by regression analysis.
3.2 Validity of the questionnaire:
- Content and face validity: As previously stated under the study's tool, the Likert scale's was face and content valid.
- Construct validity: To evaluate the Likert scale's construct validity for health education, exploratory factor analysis (EFA) was used. Utilizing the 10 Likert scale variables (items) that were obtained from the previously described Cronbach alpha analysis, factor analysis (also known as principal component analysis, or PCA) was performed. To determine whether the data were suitable for factor analysis, KMO and Bartlett's test were performed first. The data are appropriate for factor analysis since the Kaiser-Meyer-Olkin sampling adequacy score was 0.870 (P, 0.000).
Table-3 shows that the number of factors with Eigenvalues greater than one is limited to two. In the factor analysis, both factors account for 68.6% (54.7 for Factor-1 and 13.9 for Factor-2) of the total loading variance. According to the factor analysis Scree Plot, Component 2 has an "elbow" joint in it. This is the tipping point where it might not be as advantageous to extract more components. We selected two components with Eigenvalues greater than one (high-quality factors) using the scree plot, as shown in Figure-2.

▲, Extraction method: Principal component analysis
To determine the name of the component, the researcher examined the factor analysis Component Matrix, which displays Pearson's correlation coefficients of different Items (variables) with the two components that were extracted. Question 7 (general information about diabetes) had the highest correlations with component one. The strongest association between Factor-2 and Question-15 (diabetes and travel) is found. Thus, we may deduce that component-1 is titled "General Information about Diabetes," while component-2 is titled "Diabetes and Travel".
The findings of a rotated component matrix are shown in Table-4 to help identify the variables that have a strong correlation with each component. Factor-1 (Component-1) exhibited noteworthy associations with Q5: Diabetes risk factors and prevention, Q6: Prediabetes (causes, symptoms, and treatment), Q7: General information about diabetes (disease causes, diagnosis, symptoms, and kinds), and Q8: Pancreas and insulin Q9: Common oral medications for treating hypoglycemia; Q8: HbA1c and normal blood glucose levels; and Q12: Acute problems related to diabetes, such as hypoglycemia and diabetic ketoacidosis. On the other hand, Q15: Diabetes and travel; Q16: Diabetes and fasting; Q13: Chronic complications of diabetes, causes, symptoms, and treatment; and Q14: The significance of the yearly eye screening to prevent the diabetic eye complications were the Likert scale items that were contributing more and were linked to compenent-2 (Diabetes and travel). Table 4 shows the final standardized Likert scale items, which has excellent reliability and validity.
