Determination and comparison of changes in overall illness perception (Based on a qualitative criterion out of 80) before and 4 weeks after the intervention between the two groups
| Overall illness perception (Qualitative) | Intervention group | Control group | Significance level* | Effect size** |
|---|---|---|---|---|
| Before the Intervention(out of 80) | P = 0.842 | r = 0.05 | ||
| High(0–27) | 2 (3.6%) | 1 (1.8%) | ||
| Moderate(28–55) | 46 (83.6%) | 47 (85.5%) | ||
| Low(56–80) | 7 (12.7%) | 7 (12.7%) | ||
| 4 Weeks After the Intervention (out of 80) | P = 0.001 | r = 0.40 | ||
| High (0–27) | 15 (23.7%) | 1 (1.8%) | ||
| Moderate (28–55) | 40 (72.7%) | 49 (89.1%) | ||
| Low (56–80) | 0 (0%) | 5 (9.1%) | ||
* Chi-square test
** Effect size interpretation: 0.1–0.3 = small effect, 0.3–0.5 = moderate effect, > 0.5 = large effect
