We used the General Self-Efficacy Scale, the Life Orientation Test Revised, and the Revised Oxford Happiness Scale to investigate the correlations among dispositional optimism, self-efficacy, and subjective well-being in 2,578 college students. The results showed that self-efficacy, dispositional optimism, and well-being were significantly positively correlated with one another. In addition, the influence of dispositional optimism on subjective well-being was partially mediated by self-efficacy, with the mediating effect accounting for 31.6% of the total effect.

An investigation of the cognitive bias observed in optimism and the influence of optimism on psychological well-being was conducted. The cognitive bias was assumed to be related to the repressive style of information processing, represented by the trait scale of the State-Trait Anxiety Inventory and the Social Desirability scale. Optimism and well-being were measured by the Life Orientation Test and the Social Optimism scale as well as by the Life Satisfaction and Depression scales, respectively. These scales were applied to a sample of 200 individuals. Trait Anxiety and Social Desirability led to a high multiple correlation with the Life Orientation Test ( R = .54) and a moderate multiple correlation with the Social Optimism scale ( R = .30). Higher correlations were obtained for the expectation of a positive than of a negative future. Both the Life Orientation Test and the Social Optimism scale contributed to the high multiple correlation with psychological well-being ( R= .52).

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 objective of the study was to find the impact of Life Satisfaction and Life Orientation on Psychological wellbeing of Doctors working at SMS Medical College and Jaipur Dental College. The sample for the study consisted of 112 Doctors aged between 32 to 55 years (Male=60 & Female=52). Scale of Life Satisfaction Test, Revised Life Orientation Test and Bradburn Scale of Psychological Well-Being were administered on the participants. Results showed that life orientation and life satisfaction was the significant predictors of Psychological well being among Doctors. Therefore the immediate implication of this study was to ensure that prevailing working environment should enhance positive orientation towards ones living and thus in turn enhance life satisfaction for their betterment.

This research was conducted to investigate the correlation between optimism and self-esteem in midwifery college students, diploma III program. Sample from this study are midwifery college students, diploma III program who are in the region DKI Jakarta, West Java, Banten and West Sumatera. Overall, 571 midwefery student was participated in this research by filling out the questionnaire optimism and self-esteem. Optimism was measured by Life Orientation Test-Revised (LOT-R) constructed by Scheier, Carver dan Bridges (1994), while self-esteem was measured by Rosenberg’s Self-esteem Scale (RSE) constructed by Rosenberg (1965). The result show that there is a significant positive relationship between optimism and self-esteem (r = 0.378, p = 0.000). Implication of this study is, the result can be considered in designing an intervention program, in order to increase candidates midwife’s internal quality in Indonesia.

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.
