It comes from the Physical Self Inventory-10 item (PSI-10), which comes from the Physical Self Inventory -25 items, a validated questionnaire for French population.

Method

In all, 108 patients with myopathy or neuropathy and 129 individuals from the general population answered to the ISP-10 and the Rosenberg's self-esteem scale.
