V. Egan et al., DOES THE PERSONAL QUESTIONNAIRE PROVIDE A MORE SENSITIVE MEASURE OF CARDIAC-SURGERY RELATED ANXIETY THAN A STANDARD PENCIL-AND-PAPER CHECKLIST, Personality and individual differences, 24(4), 1998, pp. 465-473
Fifty-five men undergoing cardiac bypass surgery completed the state m
easure of Spielberger's State-Trait Anxiety Inventory (STAI-S) and an
anxiety-investigating personal questionnaire (PQ) using the Shapiro me
thod. Of the 55 men tested at baseline, 29 were seen immediately befor
e surgery and 51 post-operatively; 48 were followed-up 8 weeks later.
PQs were not more sensitive to anxiety than the STAI-S; when made comp
arable, both were similar in their sensitivity to anxiety. The psychom
etric properties of the PQ and the STAI-S were very similar. PQ reliab
ility was negatively correlated with lower verbal ability and higher t
rait anxiety, suggesting these characteristics affect PQ responses. PQ
techniques are psychometrically rigorous, but provide no advantage in
measurement. Concurrent personality assessment at the first and final
test sessions using the revised, abridged Eysenck Personality Questio
nnaire (EPQRA) found all four subscales of the measure highly reliable
over time (minimum test-retest r = 0.59); the only subscale to show a
significant change was a slight reduction in self-reported Psychotici
sm at followup. Despite a significant reduction in state anxiety after
life-transforming, radically health-improving cardiac bypass surgery,
the major traits of personality remained essentially stable. (C) 1998
