Answers on behavioural items, considered to be susceptible to socially desirable answer's, showed no significant differences between the two methods. The result show that the means of both sites do not differ significantly. These constructs were tested empirically by means of a questionnaire. Multiple items are designed into a scale to measure the same construct. Reliability analysis with item-analysis were used to construct summated rating scales.
Reliability analyses measure how consistently constructs are.
The lowest a we found was .59 and the highest .91. Only the most reliable scales were used in the analyses. In terms of multiple regression, the analysis technique used, the latter concepts are predictors or independent variables and the first concepts are called the dependent variables or the variables to be predicted. The concept here is that of variance. One purpose is to find out which are the most important predictors and how much of the variance of the dependent concepts they can explain.
