The Fear of Spiders Questionnaire (FSQ), an 18-item self-report questi
onnaire assessing spider phobia, was developed in an attempt to comple
ment the information provided by the Spider Phobia Questionnaire (SPQ)
. Data obtained from 338 undergraduates revealed that the FSQ was able
to discriminate phobics from nonphobics, and indicated decrements in
phobic responding from pretest to posttest following cognitive therapy
. Test-retest data, obtained from no-treatment control groups, indicat
ed that scores on the FSQ are stable over a one month period. The FSQ
also demonstrated adequate convergent validity due to its significant
correlations with the SPQ and a behavioral avoidance test. Finally, a
factor analysis revealed two factors accounting for 55% of the varianc
e. It is argued that, compared to the SPQ, items on the FSQ are more e
xplicit regarding the time period to be assessed, and may be more sens
itive to differences between phobics and nonphobics and decrements in
phobic responding following treatment.
