This study aims to adapt and validate the scale of Positive Parental Practices of the Caregiver (SP + C), in the version for children from 0 to 3 years. First, the process of cross-cultural adaptation was performed. Subsequently, for the validation of the scale, we analyzed a sample of 950 participants, with children aged between 0 and 3 years. The participants’ native language was Spanish or it was the language spoken at home. Exploratory Factor Analysis (EFA) was performed with Sample 1 (n = 483 participants), yielding 7 factors: Daily Involvement, Mentalization, Sensitivity, Promoting Learning, Attention and Organization of Daily Life, Monitoring of Parental Activity, and Parental Self-Care. Confirmatory Factory Analysis (CFA) was performed with Sample 2 (n = 467), which confirmed the factor structure of the scale. Reliability analysis showed that the scale had an adequate internal consistency. To determine criterion validity, bivariate correlations were calculated with other variables that evaluate parental competence, expecting to find significant positive relationships between them. This paper provides the standardization of the Spanish scale scores. In conclusion, the final validated scale is composed of 27 items and 7 subscales, with adequate psychometric properties. It is considered useful for the evaluation of parental competences in parents of young children.
