Abstract
The factor structure of an initial item pool of 207 positive parenting items was investigated (Manila; n = 520, 538) to develop the Positive Parenting Schema Inventory. Single group and multigroup confirmatory factor analyses of the Positive Parenting Schema Inventory showed invariance of the factor structure in six out of the seven levels on two other independent samples (Eastern, Indonesia; n = 366, 383; Western, the United States; n = 204, 214). Good values for reliability were obtained for its seven subscales (50 items) using coefficient omegas (.71 to .95). Evidence of validity based on test content, response processes (item responses to desired inferences), internal structure (exploratory and confirmatory factor analyses), relations to other variables (correlations with other instruments), and consequences of testing (correlations with positive schemas) were demonstrated. A core tenet of schema therapy theory was supported in that recall of past positive parenting patterns were associated with current levels of positive schemas.
