Table 2.
An Example 23 Factorial Trial Design for a Palliative Care Intervention
| Condition | Component #1 | Component #2 | Component #3 |
|---|---|---|---|
| 1 | 1 session | 1 session | 1 session |
| 2 | 1 session | 1 session | No session |
| 3 | 1 session | No session | 1 session |
| 4 | 1 session | No session | No session |
| 5 | 3 sessions | 1 session | 1 session |
| 6 | 3 sessions | 1 session | No session |
| 7 | 3 sessions | No session | 1 session |
| 8 | 3 sessions | No session | No session |
This factorial design should not be considered an 8-arm trial in which 7 conditions are compared to a control condition.
