Model fit: Bi-directional associations between pain and fatigue with activPAL3µ™-assessed sedentary and standing time (longitudinal)
| Health variable | Behaviour variable | χ 2 | CFI | Tucker Lewis Index | RMSEA | 90% CIs | PCLOSE | Model fit |
|---|---|---|---|---|---|---|---|---|
| Pain | Sedentary time | 4.19, P = 0.76 | 1.00 | 1.06 | 0.00 | 0.00, 0.12 | 0.81 | Excellent |
| Pain | Standing time | 4.72, P = 0.69 | 1.00 | 1.06 | 0.00 | 0.00, 0.13 | 0.76 | Excellent |
| Fatigue | Sedentary time | 6.91, P = 0.44 | 1.00 | 1.00 | 0.00 | 0.00, 0.17 | 0.53 | Excellent |
| Fatigue | Standing time | 6.82, P = 0.45 | 1.00 | 1.00 | 0.00 | 0.00, 0.17 | 0.54 | Excellent |
For χ2, degrees of freedom were 7. RMSEA encompasses 90% CIs (lower, upper) and PCLOSE for assessing model fit. χ2: χ2 statistic; CFI: comparative fit index; RMSEA: root mean square error of approximation; PCLOSE: closeness of fit.
