Results of multivariate analyses of variances of physical and psychosocial variables of the STarT Back screening tool (SBST) subgroups (N = 595)
| Effect | df | Pillai | F-value | df (num, den) | p-value |
|---|---|---|---|---|---|
| SBST | 2 | 0.66 | 31.76 | 14, 896 | < 0.001* |
| Age | 1 | 0.02 | 1.49 | 7, 447 | 0.171 |
| Gender | 1 | 0.03 | 2.09 | 7, 447 | 0.043 |
| BMI | 1 | 0.11 | 8.20 | 7, 447 | < 0.001* |
| SBST:Age | 2 | 0.03 | 0.91 | 14, 896 | 0.553 |
| SBST:Gender | 2 | 0.03 | 1.13 | 14, 896 | 0.325 |
| SBST:BMI | 2 | 0.04 | 1.25 | 14, 896 | 0.236 |
BMI: body mass index; df: degrees of freedom; Pillai: Pillai’s trace statistic; F-value: multivariate test statistic, representing the ratio of model variance to error variance; num: numerator; den: denominator; p-value: significance value, interpreted against a Bonferroni-corrected alpha of 0.0167 (0.05/3) because 3 MANOVAs were performed.
