Using data from the Fragile Family Child Wellbeing Study, we examined the Psychometric Properties of the Parental Distress Subscale of the parenting stress index--short form. Unlike previous studies, we found that the two-factor model did not fit the data significantly better than the one-factor model. Moreover, the results indicated that both the one-factor and the two-factor models provided only a marginal fit to the data. This finding was consistent across two time periods. Implications of these findings and future research are discussed.
