Orientation Test

A Scheier és Carver (1985) által kidolgozott Életszemlélet Teszt (Life Orientation Test, LOT) a vonásoptimizmus mérésére leggyakrabban használt mérőeszköz. Az optimizmus (fizikai) egészségre (úm. testi tünetek száma, gyógyulás sebessége, mortalitás és immunfunkciók) vonatkozó prediktív erejét számos vizsgálatban igazolták. A mérőeszköz eredeti (LOT), majd annak átdolgozott (LOT–R) változatát, valamint az optimizmus konstruktumát azonban sok kritika érte és éri a mai napig, amelyek egy része a mérőeszköz faktorszerkezetét, másik része pedig a vonásoptimizmus diszkriminációs validitását, illetve az úgynevezett harmadik változó problémát érinti. A skála és a fogalom, valamint az azokat ért kritikák rövid bemutatása után ismertetjük a LOT–R magyar változatának validitási, reliabilitási adatait és a feltáró és konfirmatív faktorelemzéssel kapott eredményeket. A teszt hazai változatának reliabilitás- és validitásadatai a külföldi eredményekkel összhangban jónak adódtak. A LOT–R faktorszerkezetére vonatkozó eredmények azonban nem támasztják alá egyértelműen a teszt egy- vagy kétfaktoros modelljét.

El objetivo principal de esta investigación fue adaptar y evaluar culturalmente las propiedades psicométricas del Life Orientation Test para el contexto deportivo (LOT-S). La muestra consistió en 953 jóvenes atletas brasileños de ambos sexos, con una edad media de 16 años. Los resultados del análisis factorial confirmatorio produjeron dos dimensiones correlacionadas, que reflejan optimismo y pesimismo, y brindaron apoyo para un modelo de dos factores. Se encontró un ajuste satisfactorio para LOT-S con 6 ítems (χ2=10.96, df=8; RMSEA=.020 (IC 90%=.021-.049); CFI=.995; TLI=990; NFI=.980; GFI=.996; SRMR=.032). También se generaron pruebas satisfactorias de consistencia interna a través del análisis de cargas factoriales y valores t. Los índices alfa de Cronbach (.68/ .65) y la Fiabilidad Compuesta (.72/ .65) fueron adecuados en las variables latentes Optimismo y Pesimismo, respectivamente. Los valores de varianza promedio extraídos fueron insatisfactorios, sin embargo, las correlaciones positivas con Optimismo y las correlaciones negativas con Pesimismo entre Motivación, Resiliencia y Bienestar fueron indicativas de validez convergente. Las correlaciones entre las variables latentes en comparación con las raíces cuadradas de los valores de varianza promedio extraídos de cada constructo mostraron que el modelo tiene validez discriminante. Se logró la invariancia configuracional, métrica y escalar, lo que indica que LOT-S puede medir atletas de ambos sexos por igual. Aunque se necesitan más estudios para confirmar las propiedades psicométricas del instrumento, la adaptación de LOT al contexto deportivo fue el primer paso en el futuro sobre la influencia del Optimismo en el rendimiento deportivo Palabras clave: optimismo; pesimismo; dimensionalidad; estudio de validación   The main objective of this research was to culturally adapt and evaluate the psychometric properties of the Life Orientation Test version for the sports context (LOT-S). The sample consisted of 953 young Brazilian athletes of both sexes, with a mean age of 16 years. The results of the confirmatory factor analysis produced two correlated dimensions, reflecting optimism and pessimism, and provided support for a two-factor model. A satisfactory fit for LOT-S with six items was found (χ2=10.96, df=8; RMSEA=.020 (IC 90%=.021-.049); CFI=.995; TLI=990; NFI=.980; GFI=.996; SRMR=.032). Satisfactory tests of internal consistency were also generated through the analysis of factorial loads and t-values. Cronbach's alpha (.68/ .65) and Composite Reliability (.72/ .65) were adequate in Optimism and Pessimism, respectively. The values of average variance extracted were unsatisfactory, however, positive correlations with optimism and negative with pessimism between Motivation, Resilience and Well-Being were indicative of convergent validity. The correlations between the latent variables compared to the square roots of the average variance extracted values of each construct showed that the model has discriminant validity. The configural, metric and scalar invariance was achieved, indicating that the LOT-S can measure athletes of both sexes equally. Although more studies are needed to confirm the psychometric properties of the instrument, adapting the LOT to the sport context was the first step in the future works about the influence of Optimism on sports performance.

The current study examined the factor structure and psychometric properties of the Chinese version of the Revised Life Orientation Test (CLOT-R) in a sample of 342 community-dwelling older Chinese immigrants in Canada (mean age = 71.99, SD = 5.62; 58.5% female). Confirmatory factor analysis demonstrated that the CLOT-R yields a two-factor model with one item cross-loading on two latent constructs of optimism and pessimism. Analysis further revealed poor internal consistency and convergent validity. Evidence for discriminant and convergent validity was found between optimism and perceived stress, as well as optimism and quality of life. Compared with the factor structure reported in previous Chinese-speaking samples, the modified two-factor structure found in the current group of older Chinese immigrants could be attributed to the heterogeneity of the sample and possible configural variance across culture and age. Overall, the current findings suggest that the CLOT-R may not be a reliable and valid measure to assess dispositional optimism and pessimism among older Chinese immigrants. Theoretical implications and suggestions for further scale development and research is discussed.

The psychometric properties of Scheier and Carver's 1985 Life Orientation Test (LOT), which is a measure of optimism, were examined as part of a study of education, training, work experience, and expectations of sentenced adult prisoners in Western Australia. All prisoners at five metropolitan public prisons were invited to participate and 453 accepted. This represented a response rate overall of about 41%, with response rates at each of the individual prisons ranging from 13% to 90%. The average age of the prisoner sample was 34.4 yr. ( SD= 10.2 yr.). The proportion of men in the sample was 79.7%. Mean sentence length was 66.9 mo. (58.5 for women and 69.2 for men), and the number of months of sentence remaining averaged 44.4 mo. (41.0 for women and 45.3 for men). Means and standard deviations of the LOT scores for prisoners were similar to those of other groups, and demographic differences between prisoners were not statistically significantly related to scores. The internal reliability of the LOT scores was acceptable. Confirmatory factor analyses indicated that the two-factor item-keying model fitted the prisoner data better than a one-factor model. However, the two factors did not simply reflect underlying optimism and pessimism constructs but were substantially affected by item keying.

Orientation Test

The Life Orientation Test–Revised (Scheier, Carver, & Bridges, 1994) is a widely used self-report measure of optimism. The present study examined the test's psychometric properties in a Japanese cultural context. 448 Japanese university students completed a Japanese version of the Life Orientation Test–Revised along with measures of neuroticism, extraversion, and depression. Exploratory factor analysis yielded the same two factors, positively phrased optimistic items and negatively phrased pessimistic items, as Scheier and Carver reported. Internal consistency of optimism and pessimism was acceptable. Confirmatory factor analysis of the Life Orientation Test–Revised with another group of 205 Japanese university students showed the superiority of a two-factor model of optimism–pessimism. The bidimensionality was partly due to the difference in responses between positively and negatively worded items. The Japanese data provide additional psychometric support for the Life Orientation Test–Revised and enhance the generalization of prior findings on U.S. samples to Japanese samples.
