Optimism & Pessimism Scale

Multidimensional Properties of the Lot-R: Effects of Optimism and Pessimism on Career and Well-Being Related Variables in Adolescents

“…Mroczek et al (1993) reported a moderate correlation (-.28). Dember, Martin, Hummer and Melton (1989) reported an average correlation of -.55 across two samples. Marshall, Wortman, Kuslas, Hervig and Vicers (1992) reported correlations of -.54 and -.47 in two young male samples.…”

“…Researchers have identified that there is a greater degree of independence of the constructs in older adult samples than in younger samples. The studies that have found moderate correlations of .40 or greater have generally utilised younger populations (Dember et al 1989;Marshall et al 1992;Myers & Steed, 1999). A cognitive developmental view has been proposed to account for these findings.…”

“…Lai and Wong (1998), also used confirmatory factor analysis with a Hong Kong Chinese sample and found that their adapted version of the LOT-R (C-RLOT) was best represented by a one-factor model. On the other hand, Burke, Joyner, Czech and Wilson (2000) who contrasted the LOT-R with the Optimism/Pessimism Scale (OPS; Dember et al 1989), demonstrated that the two scales were not measuring similar constructs and found only a modest correlation between LOT-R optimism and LOT-R pessimism (-.30), concluding that the two dimensions were relatively independent.…”
