The aim of this article was to analyze the construct validity and reliability of the Love Attitude Scale (LAS, Hendrick & Hendrick, 1986). The sample consisted of 381 undergraduate students (61.7 % of them women) between the ages of 17 and 25 years old. The LAS and the I- PANAS - SF (adapted by Gargurevich, 2010) that evaluates positive and negative affect were applied. The exploratory factor analysis resulted in six factors (Eros, Ludus, Storge, Pragma, Mania and Ágape), that explained 47.87 % of the total variance. The correlations between the score of Eros and Pragma styles and positive affect were positive and significant; while Manía and Ludus styles had positive and significant relationships with negative affect. Reliability by the method of internal consistency of the six factors found was from .62 to .85; while the stability coefficients for test- retest method were .44 to .77. These results allow concluding that the LAS and their scores are valid and reliable to measure attitudes toward love in the college population of Lima. / El objetivo de este estudio fue analizar la validez de constructo y la fiabilidad de la Escala de Actitudes sobre el Amor (Love Attitudes Scale [LAS]) de Hendrick & Hendrick (1986). La muestra estuvo compuesta por 381 estudiantes universitarios de Lima, Perú, (61.7 % mujeres) de entre 17 y 25 años de edad. Aparte del LAS, se aplicó el I-PANAS-SF adaptado por Gargurevich (2010), el cual evalúa el afecto positivo y negativo. Como resultados, el análisis factorial exploratorio del LAS arrojó una solución de seis factores (Eros, Ludus, Storge, Pragma, Manía y Ágape) que explicaron el 47.87 % de la varianza total. Las correlaciones entre las puntuaciones de los estilos Eros y Pragma y el afecto positivo fueron positivas y significativas; mientras que los estilos Manía y Ludus tuvieron correlaciones positivas y significativas con el afecto negativo. Utilizando el método de consistencia interna, la fiabilidad de los seis factores encontrados fue de .62 a .85; mientras que con el método testretest, los coeficientes de estabilidad fueron de .44 a .77. Estos resultados permiten concluir que el LAS y sus puntuaciones son una medida válida y fiable para medir las actitudes hacia el amor en la población de universitarios de Lima, Perú.

The problem of this study was to investigate the relationship between attitudes of love and marital adjustment through seven stages of the marital life cycle. The purpose of the investigation was to determine the changes which occur in attitude toward love and marital adjustment through the marital life cycle. The average number of subjects in each of the seven marital groups was 16, for a total of 114 couples or 228 subjects. All subjects were volunteers from three North Texas church populations.
