Table 1 A priori formulated hypotheses to evaluate construct validity
From: Psychometric properties of the psychosocial screening instrument for physical trauma patients (PSIT)
No. | Hypothesis |
|---|---|
1 | Strong and positive correlations (r ≥ 0.50) were expected between PSIT subscale 1 and the PHQ-9, STAI-S, IES-R, and a strong and negative correlation (r ≥ − 0.50) between PSIT subscale 1 and domain 2 of the WHOQOL-Bref. |
2 | Strong and positive correlations (r ≥ 0.50) were expected between PSIT subscale 2 and the STAI-S, IES-R, and the PHQ-9. |
3 | A moderate and negative correlation (r ≥ −0.30 but < −0.50) was expected between PSIT subscale 2 and domain 1 of the WHOQOL-Bref. |
4 | Strong and negative correlations (r ≥ −0.50) were expected between PSIT subscale 3 and the RSES and domains 2 and 3 of the WHOQOL-Bref. |
5 | A moderate and negative correlation (r ≥ −0.30 but < −0.50) was expected between PSIT subscale 3 and domain 1 of the WHOQOL-Bref. |
