Abstract

We examined internal consistency and test-retest reliability of a measure of dispositional optimism, the Life Orientation Test — Revised, in 121 opiate-dependent patients seeking methadone treatment. Internal consistency was adequate at baseline (α = .69) and follow-up (α = .72). Low socioeconomic status and being on disability were significantly associated with reduced internal consistency; ethnic and educational differences approached significance. Test-retest reliability was good (ICC = .72), varying across gender, race, ethnicity, education, employment and income (ICC Range = .24 –.85). Criterion validity was strong; the LOT-R was significantly negatively correlated with hopelessness (r = -.65, p < .001) and depression (r = -.60, p < .001). Findings support the use of this measure of optimism and pessimism to assess positive cognitive and emotional attributes and improve treatment strategies for opiate-dependent individuals. Future research should address the measurement and significance of optimism in minority, low socioeconomic status and poorly-educated individuals.
