Validation and Adaptation of the Brief Self-Control Scale With Spanish Adolescents: Factorial Structure and Evidences of Reliability, Validity, and Factor Invariance Across Gender and Age

During adolescence, the difficulty to control impulses is especially notable. The Brief Self-Control Scale has been used in different countries for years to study associations between self-control and other variables. However, its factor structure is not completely clear, and it is necessary to have a scale with psychometric assurances that evaluates self-control in adolescents. The aim of this study was to examine the factorial structure of the Brief Self-Control Scale and to provide evidences of reliability, validity, and factor invariance across gender and age in a sample of Spanish adolescents. Participants were 693 adolescents from Southeastern Spain, aged 13 to 18 years. Data supported an excellent fit to a two-dimensional model and evidences of reliability, validity and factor invariance across gender and age were obtained. This study provides new data on the two-dimensionality of self-control. The need of this tool becomes increasingly relevant to the susceptibility of new emerging addictions, such as mobile phones or internet.

Assessing Equivalency of PSC-17 Ratings: Does It Matter if Mixed or Grouped Item Format Is Used?

This study investigated the effect of item position on descriptive statistics, psychometric information, and factor structure of the Pediatric Symptoms Checklist 17-item social-emotional screening instrument (PSC-17). The goal was to determine whether item position, either grouped by factor or mixed across constructs, produced similar results. Descriptive statistics, reliability estimates, and model-data fit were similar across the two versions of the screener. Factor invariance tests supported strict invariance across the two versions, and very small differences between latent means for the three factors measured by the PSC-17. Both forms are equivalent for use with screening activities.
