Abstract
The aim of this study was to examine the psychometric properties of the Solution-Focused Inventory (SFI) in a Spanish population, replicating the original validation study of Grant et al. (2012). The SFI, designed to evaluate solution-focused thinking, is a 12-item scale with three subscales: Problem Disengagement, Goal Orientation and Resource Activation. The instrument was adapted and translated into Spanish, then two studies were carried out to examine its psychometric properties. The first study confirmed the instrument´s structure, and its good internal consistency. The second study confirmed its convergent validity; SFI was positively correlated with measures of well-being, resilience, satisfaction with life and perspective taking, and negatively correlated with psychopathology. This second study confirmed the stability of the SFI scores across time. In sum, these two studies provide additional support for the reliability and validity of the SFI as a measure of solution-focused thinking, and open its use to Spanish-speaking populations.
