Average reported practice score of the respondents in the STI intervention arm before the intervention was 17.6 (range 1 28, median 18), and after the intervention 21.8 (range 0 34; median 23); for the control arm it was 14.8 (range 1 26; median 16) and 18.5 (range 3 33; median 19), respectively.
Mean and median for the total knowledge score and total practice score were calculated.
Total composite score was classified into poor and better food-hygiene practice based on the median score of the population, i.e. food-hygiene practice score ≤ 19 was considered as being poor (n = 168), while a score > 19 was considered as being better practice (n = 168).
The following candidate covariates had the following β coefficients and p values before removal from practice score model: monthly income >20,000 Hong Kong dollars, β = −0.036, p = 0.956; above median avian influenza (H5N1) susceptibility score, β = 0.171, p = 0.797; above median avian influenza (H5N1) perceived severity score, β = −0.965, p = 0.143.
Mean (SD) practice score computed from 4 items (three measured on 0 3 and one 0 1), was 2.68 (2.09), with a median of 3 and range: 0 10.
Age was associated with better ranking of "help patient decide" and "make sure patient understand" statements (p < 0.001 and p = 0.002, respectively), which were ranked 1 3 by only 46%and42%2% of respondents from the current practice perspective (median ranking score 4 [2,6], p < 0.001 vs. norm perspective for both).
Overall, median scores at practice level were high (see Table 3) with relatively low variation.
A higher median knowledge score for preventive practices for toxoplasmosis was associated with a higher level of education, a planned pregnancy, having a partner, not smoking during pregnancy and ever having worked as a health care professional.
Dimension 2 ('accommodation') and 4 ('physical therapist's approach') scored highest with a median score at practice level of 100.
Significantly, only one in 11 suggested measures from the subgroup named 'An expected level of computerization in PHC practices' got a median score of 8.5, while all the others got the median score of 9.
