This thesis examines the extent to which Human-Computer Interaction (HCI) factors influence the equivalence of computer-based testing (CBT) and conventional paper-&-pencil (P&P) questionnaires in the context of mood measurement. The assessment of mood discussed in this dissertation deal largely with variation in the affective state at a fixed moment or over a short period in time. This approach permits one to characterise what dimensions of feeling there are, the degree to which they are interrelated with each other, and allows an orderly search for individual characteristics associated with affective ratings. Over 200 women volunteered to take either a CBT or a P&P version of mood assessment to test the hypothesis that accuracy of disclosure on sensitive issues is greater with a computer interaction. The CBT version showed heightened negative mood with respect to the phases of the menstrual cycle compared to the P&P administration. Heightened negative mood in CBT did not correlate with individual tendency to respond in a socially desirable way, nor familiarity with computer use. The influence of item presentation factors on affective ratings was examined, by employing a card administration of mood assessment which simulated the CBT format as closely as possible in terms of item presentation and time-to-completion. Despite controlling for the above, psychometric differences in affective ratings were found between the two modalities. Item presentation format alone therefore does not account for the non-equivalence result.
