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 a nd adapted to a Spanish population. Covariance structure analysis was used to replicate the five factor model for this questionnaire and to assess whe ther the Spanish and English versions were factorially invariant. The quest ionnaire was found to be only partially factorially invariant, as one of th e 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 SP SI-R scales are comparable across populations. Furthermore, the scales' mea ns were found to be linearly related across populations and so were the sca les' standard deviations. Hence, the scales' 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.
