Arm && Interventions

Group	Intervention	Description
Stated-Preferences Observational Group	Discrete Choice Experiment	A discrete choice experiment will be conducted with participants with peripheral neuropathic pain in the stated-preferences observational group. The instrument will measure patient preferences for topical versus systemic pain treatment.

Primary Outcome Measures

Name	Time	Method
Patient preferences for topical and systemic pain treatment attributes	20 minutes after survey start	Utility values obtained via multinominal logit estimates from discrete choice experiment

Secondary Outcome Measures

Name	Time	Method
Relevance of attributes attributed with topical and systemic pain treatment	5 minutes after survey start	Derived from Likert scale
Marginal rate of substitution against pain reduction	20 minutes after survey start	Derived from discrete choice experiment
