The study showed multiparity had a positive correlation (0.52 CI 0.32 0.85, p-value 0.009) with acceptability of labour analgesia, while age and education did not affect acceptability (p-values > 0.08).
Only 35.5% of respondents perceived A/H1N1 influenza illness as a severe disease and 12.7% had experienced A/H1N1 cases in their close relationships with higher acceptability (p<.0001 and p = .006, respectively).
The correlation coefficient between willingness-to-use and composite conditional acceptability was 0.45 (P < 0.0001), meaning that cross-structure validity of two acceptability measures was supported.
Independent factors associated with acceptability included: male sex (p = .0001); older age (p = .002); highest or lowest level of education (p = .016); non-clerical occupation (p = .011); having only one child (p = .008); and having received seasonal flu vaccination in prior 3 years (p<.0001).
Ethnic differences in acceptability of "sudden death" (p = 0.035) and "immediate death" (p = 0.033) were observed, with Indian subjects finding these descriptors less acceptable than Chinese or Malay subjects.
Two important concepts of the acceptability of an argument p in such systems are credulous acceptance to capture the notion that pcan be 'believed'; and sceptical acceptance capturing the idea that if anything is believed, then pmust be.
Data also shows a certain correlation between active and attitudinal acceptability (r = 0.491, p < 0.001); respondents who are negative towards the concept itself are less willing to actively report own travel data.
