Abstract
The Hamilton Depression Rating Scale (HAMD) is widely used in studies to measure change in the severity of depression.
Th ere are reports of established reliability and validity of the HAMD in both inpatient and outpatient psychiatric patients.
However, there are no published psychometric studies of the HAMD in a methamphetamine using population. Given that
the symptoms of depression and intoxication or withdrawal from methamphetamine overlap, it is possible that the HAMD
does not measure severity of depression in individuals who use methamphetamine. Th us, we are conducting a psychometric
evaluation of the HAMD in methamphetamine users with and without depression. Th is evaluation is currently underway, and
we anticipate having results in 6-8 weeks.
