Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will involve a Cognitive Behavioural Therapy (CBT) based self-help program called “Helping Health Anxiety” developed by the Centre for Clinical Interventions (CCI). There are nine modules providing the following intervention components: psychoeducation; attention training; worry postponement; thought diaries; reducing unhelpful checking and reassurance seeking; challenging avoidance and safety behaviours (exposure); adjusting health rules and assumptions; healthy living; and self- management planning (Anderson, Saulsman, & Nathan, 2011). Each week, over nine weeks, one module will be sent to the participants via email. Each module takes approximately 1 hour to complete, plus any time the participant spends on doing the associated practice tasks throughout the week. Each week the participants are required to complete a questionnaire via email, before they are sent the module, in order to tracks their Health Anxiety.
Their experience of the modules will also be explored during the follow-up interview (a month after the intervention is completed).

Post-test (post-intervention) scores will be compared to each individual's Pre-test (pre-intervention) scores.
