[Factor structure and internal consistency of the Spanish version of the Parenting Stress Index-Short Form].

The aim of this study was to analyze the psychometric properties of the Spanish version of Parenting Stress Index-Short Form. After translating the instrument from English into Spanish using the forward-backward translation method, it was administered to a sample of 129 mothers of children aged between 10 and 39 months olds. The exploratory factor analysis identified two factors: Childrearing Stress and Personal Distress, which accounted for 48.77% of the variance. The internal consistency of these factors was high (Childrearing Stress: .90 and Personal Distress: .87). Implications of these findings and suggestions for future research are discussed.
