Objective: The aims of the present study were to examine the presence of sluggish cognitive tempo (SCT) symptoms in children; associations of the symptoms with sociodemographic characteristics of the children; and relationships between SCT symptoms and symptoms of ADHD, dyslexia, academic performance, and behavioral problems. Method: We evaluated Catalan schoolchildren aged 7 to 10 years in Barcelona, 2012-2013. Parents filled out the SCT–Child Behavior Checklist (SCT-CBCL), the Strengths and Difficulties Questionnaire (SDQ), and a questionnaire concerning sociodemographic characteristics. Teachers completed the ADHD criteria of Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) (ADHD-DSM-IV), a list of dyslexia symptoms, and evaluated the children’s academic performance. SCT symptoms were studied as a continuous and dichotomous variable. Results: In all, 11% of the children in our sample scored above the clinical cut-off on the SCT-CBCL scale. We observed a higher rate of SCT symptoms in boys, children whose father was unemployed, those whose maternal educational level was lower, children with a high socioeconomic vulnerability index at home, those who reported maternal smoking during pregnancy and current second-hand smoke exposure at home, and children with an ADHD diagnosis. More SCT symptoms were associated with inattention symptoms, symptoms of dyslexia, academic problems, and emotional and peer relationship problems. Conclusion: We observed a higher prevalence of SCT symptoms in our sample than expected in the general population. While girls are less prone to SCT symptoms, some socioeconomic indicators, dyslexia, and inattention symptoms as well as exposure to smoking at home increase the risk of SCT and must be taken into account during assessments.

Resumen: Las autolesiones en adolescentes han adquirido mayor relevancia en los últimos años, por el aumento de prevalencia, el mayor riesgo de realizar una tentativa autolítica y de desarrollar un trastorno límite de la personalidad o un trastorno depresivo mayor. Nuestro objetivo es revisar la bibliografía referente a tratamientos psicológicos para las autolesiones no suicidas (non-suicidal self-injury; NSSI). Se incluyen estudios que evalúan una intervención psicoterapéutica para el tratamiento de las autolesiones. Los resultados indican que ningún tratamiento para las autolesiones ha demostrado sufi ciente evidencia en adolescentes. La terapia basada en mentalización (MBT-A) ha demostrado efi cacia en un estudio y la terapia dialéctica-conductual (DBT-A) ha demostrado efectividad. La variedad y heterogeneidad de resultados difi culta extraer conclusiones más específi cas, como cuáles son los componentes activos efi caces. Valoramos la necesidad de estandarizar criterios e instrumentos en el campo del tratamiento de las autolesiones para mejorar la validez y utilidad de los resultados.

Non-suicidal self-harm in adolescents: A review of psychological treatmentsAbstract: Self-harm in teenagers has become more important in recent years, given its increased prevalence and the greater risk involved of making a suicidal attempt and developing a borderline personality disorder or a major depressive disorder. We aim to review the literature as to psychological treatments for non-suicidal self-injury (NSSI). Studies assessing a psychotherapeutic intervention for self-harm have been included. The results indicate that no treatment for self-harm has demonstrated enough evidence in adolescents. Mentalization based therapy (MBT-A) has shown effi cacy in one study and the dialectical behavior therapy (DBT-A) has shown effi cacy. However, the variety and heterogeneity of results make it diffi cult to draw more specifi c conclusions, such as regards the effective active components. Criteria and instruments in the fi eld of the treatment of NSSI need to be standardized in order to improve the validity and clinical utility of results.
