Table 5. Transitional class proportions from time 1 to time 2 based on the estimated longitudinal latent transition analysis.
| LTA class | Time 1 | Time 2 | N (n=1275) | Trajectory |
|---|---|---|---|---|
| 1 | Class 1 (comorbid) | Class 1 (comorbid) | 79 (0.06) | Persistent (P) |
| 2 | Class 1 (comorbid) | Class 2 (low symptom) | 53 (0.04) | Recovery (R) |
| 3 | Class 1 (comorbid) | Class 3 (depression) | 135 (0.11) | Persistent (P) |
| 4 | Class 2 (low symptom) | Class 1 (comorbid) | 76 (0.06) | Incident (I) |
| 5 | Class 2 (low symptom) | Class 2 (low symptom) | 251 (0.20) | Low symptom (L) |
| 6 | Class 2 (low symptom) | Class 3 (depression) | 94 (0.07) | Incident (I) |
| 7 | Class 3 (depression) | Class 1 (comorbid) | 148 (0.12) | Persistent (P) |
| 8 | Class 3 (depression) | Class 2 (low symptom) | 246 (0.19) | Recovery (R) |
| 9 | Class 3 (depression) | Class 3 (depression) | 193 (0.15) | Persistent (P) |
Note: derivation of four rational trajectories based on the longitudinal transition classes:
(1) persistent trajectory=(LTA classes 1+3+7+9=555, 43.5); (
2) recovery trajectory=(LTA classes 2+8=299, 23.5); (
3) incident trajectory=(LTA classes 4+6=170, 13.3); (
4) low-symptom trajectory=(LTA class 5=251, 19.7).
