Mediators of behaviour change (eg, beliefs about pleasure, motivation, knowledge, self-efficacy), behavioural outcomes (including condom use, STI testing, communication with partner/s) and cumulative STI incidence (self-reported and from clinical notes) will be measured.
46 We could have streamlined our behavioural measures further in the interests of shortening the questionnaire but guided by our evaluation framework we considered it essential to retain a degree of contextual specificity in our measures, both of walking and cycling behaviours and of the putative correlates and mediators of those behaviours.
The survey measured nurses': role satisfaction, perceived utility of training, frequency, and potential behavioural mediators of, preventive delivery.
Correlation co-efficients (Pearson's r or Spearman's rho) appropriate to each item's level of measurement were used to examine the uni-variate associations between demographic characteristics, job satisfaction, utility of training and potential behavioural mediators of preventive delivery with the five measures of frequency of preventive delivery.
In order to identify those potential behavioural mediators of preventive delivery (theoretically amenable to change), that were most strongly and independently associated with the preventive outcomes, multivariable linear regression models were run using a stepwise variable selection method with a strict p < 0.001 for model entry.
Interviews with men checked their understanding of questions, the clarity of questions, and content suitability for the selected measures of behavioural outcomes and mediators of those outcomes.
The latter study used a different behavioural test, i.e., sweetened milk intake, therefore, alternative explanations for the lack of effect of COX-2 specific inhibition in our study might be that different phases of behavioural changes and different types of behaviour (e.g., exploratory, anxiety, sickness) are regulated by different mediators.
After the analysis of behavioural changes, mice were sacrificed and tissue collected for analysis of inflammatory mediators in serum and brain.
Self-efficacy is a stronger predictor of behavioural change, and has also been found to be an important mediator of the relation between knowledge and behaviour [ 18, 19].
