The Perceived Sensitivity to Medicines Scale™

The Perceived Sensitivity to Medicines Scale (PSM™) assesses personal sensitivity to the positive and negative effects of medicines.

How does it work?

The scale is comprised of five items which assess beliefs about the self in relation to medicines; specifically, personal sensitivity to the positive and negative effects of medicines. High scores on the PSM™ are likely to be associated with a higher incidence of adverse effects and early discontinuation of treatment due to side effects.

Where can it be used?

The PSM™ was originally developed and tested within samples of HIV, hypertension and travel vaccination patients. This provided initial support of its validity and reliability. It has since been used in a range of disease areas including:

  • HIV
  • Travel vaccination
  • Stroke
  • Diabetes
  • Hypertension
  • Epilepsy
  • Asthma
  • Rheumatoid Arthritis

Where has it been used?

The PSM™ scale has been used within the UK, New Zealand, Norway, China, and Greece (Greek version.)
