Standardized response means (SRMs). The higher the score the more impact from the intervention. Standardized response means show the responsiveness of a certain parameter’s effect on HRQoL. Thus equals the estimated HRQoL for the standard Swedish population. Responsiveness is showing the validity of SF-36 on gallstone surgery. High responsiveness proves that the instrument used for measuring the improvement after gallstone surgery, in this case SF-36, is reliable.

Evaluation of SRM [10]: (i) <0.20: trivial effect; (ii) 0.20–0.50: small effect; (iii) 0.50–0.80: moderate effect; (iv) >0.80: large effect. |
