From: Mental and physical comorbidity in an Arab primary health care setting
Number of physical illnessesa | PHQ-15: Somatization | GAD-7: Anxiety | PHQ-9: Depression |
|---|---|---|---|
Mean (SD) | Mean (SD) | Mean (SD) | |
No physical illness (n = 376) | 6.8 (4.7) | 4.6 (4.5) | 5.6 (4.9) |
One physical illness(n = 275) | 8.5 (5.9) | 5.9 (5.3) | 6.8 (6.2) |
Two physical illnesses (n = 148) | 9.6 (6.3) | 6.9 (6.2) | 8.1 (6.9) |
Three or more physical illnesses (n = 33) | 11.1 (6.2) | 8.6 (7.7) | 8.7 (6.5) |
Statistics, p value | F3, 828 = 18.9, p < 0.001 | F3, 828 = 13.9, p < 0.001 | F3, 828 = 10.8, p < 0.001 |
Multiple comparisons | 3 & 2 illnesses > 1 and no illness | 3 & 2 illnesses > 1 and no illness | 3, 2, and 1 illnesses > no illness |
Specific physical illness | |||
Diabetes mellitus (n = 248) | 8.3 (5.9) | 6.3 (6.0) | 7.0 (6.6) |
Hypertension (n = 229) | 8.9 (5.9) | 6.5 (6.3) | 7.4 (6.6) |
Heart disease (n = 48) | 10.0 (6.4) | 7.5 (7.1) | 8.2 (6.8) |
Asthma (n = 82) | 11.8 (6.6) | 7.3 (5.2) | 8.9 (6.2) |
p value | F3,603 = 7.4; p < 0.01 for asthma vs. diabetes and hypertension | P > 0.05 | F = 1.9; p > 0.05. But for asthma vs. diabetes: t = 2.4, p < 0.02 |
