title: Spanish version of the savings inventory-revised: adaptation, psychometric properties, and relationship to personality variables.
abstract: The factor structure, psychometric properties, and relationship with personality variables of a Spanish version of the Savings Inventory-Revised (SI-R) are investigated in a sample of 381 undergraduate students. A maximum likelihood factor analysis suggests a three-factor structure, which is similar but not identical to that of the original English version. The three factors mirror the three hypothesized domains of compulsive hoarding: acquisition, difficulty discarding, and clutter. The Spanish SI-R demonstrates acceptable high internal consistency and test-retest reliability, but its divergent validity is weaker than expected because of a significant overlap with depressive symptoms. Different SI-R factors are associated with different personality traits: Whereas the difficulty discarding dimension is predominantly associated with susceptibility to punishment, the acquisition dimension is predominantly associated with susceptibility to reward. The authors conclude that the Spanish SI-R is a promising instrument to measure hoarding symptoms.
