Testing the final version of HAGOS Missing data HAGOS: Few individual items were missing. At baseline, 9 items from a total of 101 patients x 37 items = 0.2%, were missing. A total score could be calculated for all subjects for all subscales except for PA, where a total score could be calculated for all but one subject. At retest, 1 item of 44 patients x 37 items = 0.1% was missing. Test-retest analyses could be performed for 44 subjects for all subscales except for PA, where test-retest analysis could be calculated for 43 subjects. At the 4-month follow-up, 21 items of 87 patients x 37 items = 0.7%, were missing. SF-36: Few individual items were missing. At the baseline measurement, 7 items of 101 patients x 36 items = 0.2% were missing. A total score could be calculated for all subjects for all subscales. Test-retest reliability and measurement error Table 8 shows ICCs, SEM and SDC of all subscales of the HAGOS. Retest was completed within a mean of 11 days, and a range of 7 to 21 days. For all subscales of the HAGOS, the ICCs were between 0.82 and 0.92 indicating good test-retest reliability. The SDC at the individual level ranged from 17.7 to 33.8 points and at group level from 2.7 to 5.2 points for the different subscales. Construct validity Generally higher correlations were found between the HAGOS subscales and the SF-36 subscales of Physical Function, Physical Role and Bodily Pain (convergent construct validity) than between the HAGOS and the SF-36 subscales of Mental Health, Vitality, Role-Emotional, Social Functioning, and General Health (divergent construct validity) (Table 9). 44
As hypothesized, the correlations between the HAGOS subscales ADL and Sport/Rec and the SF-36 subscale Physical Function were at least 0.5, and higher than for the other HAGOS subscales (Pain, Symptoms, PA and QOL). The correlations between the HAGOS subscales Pain and Symptoms and the SF-36 subscale Bodily Pain were at least 0.5 and 0.4 respectively and as hypothesized, higher than for the HAGOS subscales PA and QOL, but not higher than for the HAGOS subscales Pain and Symptoms. The subscale QOL was moderately correlated to the SF-36 subscale Mental Health, at 0.38 but did not reach the hypothesized threshold of being at least 0.4. Table 9.
