Gender differences in avoidance and repetitive negative thinking following symptom provocation in men and women with spider phobia.

OBJECTIVES

Women's greater prevalence of anxiety disorders compared to men is widely assumed to be partly due to gender differences in cognitive and behavioural factors that perpetuate anxiety, such as repetitive negative thinking (RNT) and avoidance. However, past studies assessing this assumption have not controlled for gender differences in baseline symptom severity, the type of stressful life experiences against which RNT and avoidance are measured, or emotional reactivity to these experiences.

DESIGN

Using a two-group design, the present study controlled for these confounds by comparing avoidance and RNT in relation to a controlled symptom provocation task in spider phobic men and women with equivalent spider fear severity on the Fear of Spiders Questionnaire.

METHODS

Participants engaged in a behavioural approach test (BAT) involving a live spider, during which they were assessed for avoidance (physical proximity to the spider) and subjective distress. Two weeks later, participants reported on their levels of negative affect and RNT experienced during the preceding weeks in relation to the BAT.

RESULTS

Women exhibited greater avoidance and reported greater RNT than men, despite reporting comparable distress and negative affect. Gender remained a significant predictor of avoidance when accounting for distress and also remained a significant predictor of RNT when accounting for depressive symptoms and negative affect.

CONCLUSIONS

These results provide in vivo evidence that heightened avoidance and RNT may perpetuate anxiety symptoms in women independently of gender differences in symptom severity, daily experiences, or emotional reactivity.

PRACTITIONER POINTS: Following symptom provocation, men and women with spider phobia differ in cognitive and behavioural coping responses. Women exhibit greater avoidance and repetitive negative thinking than men, and these differences are not attributable to gender differences in symptom severity or emotional reactivity. These findings provide novel evidence for gender differences in maintaining factors that perpetuate anxiety disorders whilst accounting for confounding factors present in prior research.
