Cross-cultural adaptation and measurement properties of the Dutch knee self efficacy scale (K-SES)

Table 1 Hypotheses about the relation between K-SES-D and other variables

1	K-SES-D will show 2 dimensions in exploratory factor analysis: present and future self-efficacy.
2	K-SES-D will fit the proposed 2 dimension model using confirmatory factor analysis.
2	K-SES-D_present will have a high positive correlation with knee function (KOOS) (0.50 < r < 0.80).
3	K-SES-D_future will have a low correlation with knee function (KOOS) (0.30 < r < 0.50).
4–5	K-SES-D_present and K-SES-D_future., both have moderate to high correlations with TSK (0.50 < r < 0.80).
6–7	K-SES-D_present, K-SES-D_future. both will have strong correlations with PCS (0.50 < r < 0.80).
8	K-SES-D_present, K-SES-D_future., both will have low association with MHLC (0.30 < r < 0.50).
9	K-SES-D_present, K-SES-D_future., both will have low association with HADS (0.30 < r < 0.50).
