Abstract
in English, Spanish

Background/objective: This study aims to analyze the psychometric properties of the Satisfaction with Life Scale (SWLS), examining the reliability of scale scores and providing validity evidence for its use with breast cancer patients. We provide validity evidence based on internal structure and on relationships with positive psychological variables and other variables indicative of psychological adjustment.

Method: Participants were 222 Spanish women with a diagnosis of breast cancer. They completed the SWLS and a battery of questionnaires measuring positive and negative affect, self-esteem, resilience, emotional intelligence, flourishing, optimism, depression, anxiety, and stress.

Results: Confirmatory factor analysis supported a single-factor structure for the SWLS, S-B χ2 (5) = 7.36, p = .19, CFI = .99, NNFI = .99, RMSEA = .046. The reliability of test scores estimated with McDonald's omega yielded a value of .80. Validity evidence was provided by a positive correlation between SWLS scores and positive affect, self-esteem, resilience, emotional intelligence (specifically, clarity and repair), flourishing, and optimism (range: .24, .69), and by a negative correlation with negative affect, pessimism, depression, anxiety, and stress (range: -.25, -.59).

Conclusions: The Spanish version of the SWLS showed satisfactory psychometric properties and it is an appropriate measure for use in the breast cancer context.

Antecedentes/objetivo: El objetivo deestudio es examinar las propiedades psicométricas de la Escala de Satisfacción con la Vida (SWLS), analizando la fiabilidad de sus puntuaciones y aportando evidencias para su uso en pacientes con cáncer de mama. Se proporcionan evidencias de validez basadas en la estructura interna y en la relación con otras variables psicológicas positivas y con otras indicativas de ajuste psicológico.

Método: Han participado 222 mujeres españolas diagnosticadas de cáncer de mama, que cumplimentaron la SWLS y medidas de afecto positivo y negativo, autoestima, resiliencia, inteligencia emocional, florecimiento, optimismo, depresión, ansiedad y estrés.

Resultados: El análisis factorial confirmatorio indicó una estructura unidimensional, S-B χ2(5) = 7,36, p = 0,19, CFI = 0,99, NNFI = 0,99, RMSEA = 0,046. La fiabilidad de las puntuaciones estimadas con omega de McDonald fue de 0,80. Las evidencias de validez mostraron correlaciones positivas entre las puntuaciones de SWLS y afecto positivo, autoestima, inteligencia emocional (específicamente, claridad y reparación), florecimiento y optimismo (rango 0,24 0,69), así como correlaciones negativas con afecto negativo, pesimismo, depresión, ansiedad, y estrés (rango -0,25 - 0,59).

Conclusiones: La versión española de la SWLS muestra adecuadas propiedades psicométricas, siendo una medida apropiada para utilizarla en pacientes de cáncer de mama.
