Mood change and computer anxiety: A comparison between computerised and paper measures of negative affect

摘要

The lack of equivalence between computerized and pencil-and-paper administration in measures of negative affect have been attributed to variance created by negative affect towards computers or computer anxiety (CA). In the current study, paper baseline computer anxiety and state/trait anxiety measures were obtained from 51 first-year psychology undergraduate volunteers. Further measures were taken by either paper or computer before and after students received their grade for the first research methods practical report of the course. Levels of state anxiety (SA) were found to increase significantly at this time. A lexical decision task was completed at each measurement stage as an additional behavioural mood indicator. Results revealed that CA was only related to SA prior to receipt of grade, at a point where equivalence between administration method of measures had been demonstrated. Non-equivalence in measurement of SA occurred after students had received their mark, in that levels of anxiety increased in the computer condition and decreased in the paper condition. Lack of equivalence, therefore, appears to be a function of psychological stress, characterised by affective modulation rather than CA.
