title: Use of the Life Optimism Test among adolescents in a clinical setting: a report of reliability testing.
abstract: This study examined the consistency and reliability of the Life Optimism Test (LOT) among patients attending an adolescent medicine clinic. The LOT had good internal consistency (Cronbach's alpha ranging from 0.56 at pretest to 0.76 at posttest) and good 1-week test-retest reliability (intraclass correlation = 0.84). These data support use of the LOT to measure optimism among adolescents.
