Terry, P. and Barron, J. (2011) Factorial and concurrent validity of two anxiety measures and anxiety responses among vision-impaired people. In: 46th Australian Psychological Society Annual Conference 2011, 4-8 Oct 2011, Canberra, Australia.
The present research tested the factorial and concurrent validity of a revised version of the Competitive State Anxiety Inventory -2 (CSAI-2), a commonly-used measure of anxiety in competitive domains since its development by Martens, Vealey and Burton in 1990. A revised 17-item version of the CSAI-2, known as the CSAI-2R, was created by Cox, Martens and Russell in 2003, which has shown superior psychometric characteristics and is now favoured over the original by researchers. Another measure, the Emotion and Mood Components of Anxiety Questionnaire (EMCA-Q), developed by Beedie, Lane and Terry in 2005, was used as the concurrent measure. Using a retrospective recall approach, and with the assistance of specialist Job Access With Speech (JAWS) software, 152 adult vision-impaired participants completed an on-line questionnaire that included a range of demographic information plus the CSAI- 2/CSAI-2R and EMCA-Q. The usual context of the measures, competitive sport, was re-contextualised to a personally-important event in which the participants had recently ―performed.‖ Principal components analysis with promax rotation showed that the CSAI-2R provided a better fit to the data than the original CSAI-2, explaining 63% of the variance compared to 59%, but complex solutions were found for both measures including several cross-loading items. The factorial validity of the EMCA-Q was supported. The concurrent validity of the CSAI-2R and EMCA-Q was supported via inter-correlations between subscale scores that were exactly in line with theoretical predictions. Group comparisons using single-factor MANOVAs showed no significant differences in anxiety responses among the vision impaired population by gender, age and level of vision impairment. Those with a previously diagnosed anxiety disorder reported higher anxiety scores than those without such a diagnosis. Finally, participants who resided in Australia reported higher level of anxiety scores than those residing outside Australia. The EMCA-Q appears to be a valid measure to use for the vision-impaired people in terms of its factor structure, internal consistency and variance explained, whereas further validation work would be required before the CSAI-2R could be considered validated for use with vision-impaired populations.
