External factors which might influence intervention acceptability and suitability

Factors affecting intervention acceptance	Methods to address these factors
Scepticism and resistance	Clear information at screening about the nature and style of the intervention (cognitive behavioural therapy) and about the link between what we do, the way we think and our physical symptoms
Some will be sceptical and resistant to the idea of a ‘counselling’ approach to preventing chronic widespread pain
Timing	Intervention impact may be increased if offered earlier rather than later, for example, when participants are experiencing low to moderate pain.
Timing of the intervention offer could impact on acceptability and suitability
Baseline Knowledge	Intervention screening should include assessment of baseline knowledge and existing use of self-help and CBT pain management techniques
Intervention most useful for those with little or no prior experience of CBT pain management techniques
Presenting Symptoms	Intervention screening should include assessment of symptoms experienced. Intervention is likely to be most helpful for those with Musculoskeletal pain.
The presenting symptoms experienced may impact on acceptability and suitability
