Psychometric properties of the Spanish adaptation of the Social Problem-Solving Inventory-Revised (SPSI-R)

The Social Problem Solving Inventory-Revised (SPSI-R) has been translated and adapted to a Spanish population. Covariance structure analysis was used to replicate the five factor model for this questionnaire and to assess whether the Spanish and English versions were factorially invariant. The questionnaire was found to be only partially factorially invariant, as one of the dimensions measured by the questionnaire, impulsivity/carelessness style (ICS), appears to be measured differently across populations. As a result, the correlations between the ICS scale and the remaining SPSI-R scales differ across populations. The correlations among the remaining SPSI-R scales are comparable across populations. Furthermore, the scalesʹ means were found to be linearly related across populations and so were the scalesʹ standard deviations. Hence, the scalesʹ metrics can be linked linearly across populations. The scales of the Spanish version of the SPSI-R showed adequate reliability and, as in North American samples, gender differences were found in NPO in the Spanish sample.
