Psicothema was founded in Asturias (northern Spain) in 1989, and is published jointly by the Psychology Faculty of the University of Oviedo and the Psychological Association of the Principality of Asturias (Colegio Oficial de Psicología del Principado de Asturias).
We currently publish four issues per year, which accounts for some 100 articles annually. We admit work from both the basic and applied research fields, and from all areas of Psychology, all manuscripts being anonymously reviewed prior to publication.

Background: The short S-UPPS-P is a 20-item self-report tool for assessing impulsivity in adolescents, differentiating five dimensions: Negative Urgency, Lack of Perseverance, Lack of Premeditation, Sensation Seeking, and Positive Urgency. This study aimed to evaluate the psychometric properties of the Spanish S-UPPS-P and to establish normative data for adolescents in Spain. Method: Participants were 8,944 adolescent students (ages 11-19) from 66 high schools and 789 adolescent psychotherapy patients from 7 centers. Results: The expected 5-factor model, evaluated with confirmatory factor analysis (CFA), showed insufficient fit (CFI and TLI ≤ .90, RMSEA = .076). However, an exploratory approach yielded satisfactory results (CFI and TLI ≥ .97, RMSEA ≤ .036), with full measurement invariance across age, gender and sample type. Internal consistency reliability ranged from moderate to excellent (ω = .67-.82). Convergent validity with the Barratt Impulsiveness Scale total score was satisfactory (r = .47-.59). No significant differences in scale scores were observed across gender, age, or sample type, providing the use of a single norm. Conclusions: These findings support the S-UPPS-P as a valid, reliable tool for assessing impulsivity in Spanish adolescents. The availability of standardized norms enhances its utility in clinical and educational contexts.
Antecedentes: El S-UPPS-P es un instrumento de 20 ítems para evaluar la impulsividad en adolescentes, diferenciando cinco dimensiones: Urgencia Negativa, Falta de Perseverancia, Falta de Premeditación, Búsqueda de Sensaciones y Urgencia Positiva. Este estudio evaluó sus propiedades psicométricas y estableció datos normativos en adolescentes españoles. Método: Participaron 8.944 estudiantes (11-19 años) de 66 institutos y 789 pacientes adolescentes de salud mental. Resultados: El modelo de cinco factores, evaluado mediante análisis factorial confirmatorio (AFC), mostró ajuste insuficiente (CFI y TLI ≤ .90, RMSEA = .076). Sin embargo, un enfoque exploratorio mostró resultados satisfactorios (CFI y TLI ≥ .97, RMSEA ≤ .036), con invariancia completa del modelo de medida en función de la edad, género y tipo de muestra. La consistencia interna fue moderada a excelente (ω = .67-.82), y la validez convergente con la Escala de Impulsividad de Barratt fue adecuada (r = .47-.59). No se hallaron diferencias significativas en las puntuaciones según género, edad o muestra, permitiendo el uso de un único baremo. Conclusiones: Estos resultados apoyan al S-UPPS-P como un instrumento válido y fiable para evaluar la impulsividad en adolescentes españoles. La disponibilidad de baremos aumenta su utilidad en contextos clínicos y educativos.
