The Life Orientation Test has been widely used with various populations since its development, but its psychometric properties among older adults have not been assessed. This study employed exploratory factor analysis to examine the factor structure of a modified version of the test for 90 frail older women. The results do not support a unidimensional conceptualization of optimism. Internal consistency reliability was lower for the entire scale than for separate factors representing positively versus negatively framed questions. Some support for construct validity was shown by small to moderate correlations with several related constructs. The results were likely to have been affected both by the modification of the test to simplify data collection with an elderly population and by a differing manifestation of the construct among functionally impaired older adults as compared to previous research with younger, healthier samples.

Abstract The Life Orientation Test (LOT; Scheier & Carver, 1985) was developed as a measure of dispositional optimism. Optimism has been linked to positive life outcomes and is associated with psychological (Carver & Gaines, 1987; Scheier & Carver, 1985) and physical (Scheier & Carver, 1987; Scheier et al. 1989) well-being. The current study assessed 520 people placed into three age groups: young adult (n =149), middle-age adult (n = 252), and older adult (n = 119). The mean age for the young group was 19.24 (SD = 2.01), middle-aged (47.68 (SD = 4.75), and old was 71.99 (SD = 7.21). Data were submitted for a confirmatory factor analysis (CFA) which tested for invariance across the age groups. Previous factor analyses have identified two distinct factors representing optimism and pessimism. Results from the CFA showed that both Configural and Metric invariance models demonstrated acceptable fit for the two factor model (□2(df=57) = 61.92, p = 0.3047; □2(df=69) = 78.77, p = 0.1974). In contrast, Scalar invariance resulted in a poor fit across the three age groups (□2(df=81) = 139.288, p < 0.0001). Model comparisons revealed no significant differences between Configural and Metric models (□2(df=12) = 16.996, p = 0.1498). Model comparisons between Configural and Scalar and Metric and Scalar were (□2(df=24) = 78.947, p < 0.0001; □2(df=12) = 61.764, p < 0.0001). These results confirm previous research that shows a correlated two factor model consistent with the concept that optimism and pessimism are correlated elements rather than two ends of a continuum.

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.

Life orientation test-revised (LOT-R) is a common scale used to assess dispositional optimism. There is no consensus regarding the dimensionality of this scale. To date, no psychometric study regarding this scale has been conducted among patients with esophageal cancer. In this Swedish nationwide population-based study, we conducted a series of confirmatory factor analysis to assess the dimensionality of LOT-R among patients with esophagectomy for cancer. In total, 197 patients were included. Based on the results, we removed the first negatively worded item, and adopted the one general factor (dispositional optimism) model with correlated errors between reversed negatively worded items.

Zusammenfassung. Ziel der vorliegenden Studie ist die Untersuchung der psychometrischen Eigenschaften, faktoriellen Struktur und konvergenten Validität der deutschsprachigen Version des Parent Rated Life Orientation Test of Children (PLOT) zur Messung von Optimismus und Pessimismus bei 4 bis 6-jährigen Vorschulkindern. Eltern von 145 Kindergartenkindern (77 Mädchen; Alter: M = 5.0, SD = 0.6 Jahre) schätzten Optimismus und Pessimismus sowie Emotionsregulation der Kinder ein. Außerdem wurde das Problemverhalten der Kinder (Eltern- und Erzieherinneneinschätzung) erfasst. Konsistent zu Studien mit Schulkindern und Jugendlichen zeigte sich eine zweidimensionale Faktorenstruktur mit einem Optimismus- und einem Pessimismusfaktor. Die Ergebnisse ergaben theoriekonforme Zusammenhänge mit Problemverhalten und Emotionsregulation der Kinder. Insgesamt weisen die gefundenen Reliabilitäts- und Validitätswerte auf eine gute Verwendbarkeit des PLOT bei Vorschulkindern hin. Das neue Messverfahren kann einen Beitrag zum besseren Verständnis von Zukunftserwartungen bei Vorschulkindern leisten und als Screening-Instrument zur Identifikation von Kindern mit einem Entwicklungsrisiko dienen.

El presente estudio tuvo por objetivo determinar la relación existente entre autoconepto personal, nivel de ansiedad y comprensión lectora en estudiantes de educación secundaria. El diseño que se reporta es descriptivo correlacional. La muestra estuvo constituida por 260 estudiantes varones y mujeres del VII ciclo de educación secundaria del colegio N°0025, del distrito de Ate, de la Urbanización San Gregorio, a quienes se les aplicaron los siguientes instrumentos: el cuestionario de autoconcepto personal (APE) de Eider Goñi Palacios (2009); la escala de ansiedad, el LOT, y el LOT-R; Life Orientation Test, de Sheier, Carver y Bridges (1994); y la prueba de comprensión lectora de Cabanillas (2004). A partir del análisis de los resultados, se concluye que existe una relación significativa entre autoconcepto personal, nivel de ansiedad y comprensión lectora en estudiantes de educación secundaria.
