This research examines the internal consistency, convergent validity, and sensitivity, specificity, and positive and negative predictive value of the Spanish version of the Eating Disorder Examination-Self-Report Questionnaire (S-EDE-Q), as a screening questionnaire for eating disorders (ED) in a community sample. Participants were 1543 male and female Spanish-speaking students (age range: 12-21 years), who volunteered to complete the S-EDE-Q and the EAT-40. The Spanish version of the Eating Disorders Examination (S-EDE) interview, 12th edition, was administered to 602 of the students. Acceptable internal consistency for the four subscales of the S-EDE-Q was obtained (α ≥ .74). Corrected pointbiserial correlation performed with the 22 items included in the S-EDE-Q subscales showed acceptable values for all the items. The EAT-40 Dieting subscale correlated highly and positively with the four S-EDE-Q subscales (r ≥ .70). Acceptable results in sensitivity, specificity, and positive and negative predictive value when compared with the EDE were found. Correlation between S-EDE and S-EDE-Q diagnoses was positive and significant. Overall, results support the psychometric adequacy of the S-EDE-Q as a screening questionnaire for ED in community samples.

Resumen: El objetivo de esta investigación es evaluar empíricamente la eficacia de un programa de intervención breve y específico para el tratamiento del trastorno de estrés postraumático (TEPT) en mujeres víctimas de violencia doméstica. Participaron 34 mujeres mexicanas víctimas de malos tratos por parte de su pareja, todas con diagnóstico de TEPT (DSM-IV-TR). El programa de tratamiento, aplicado en formato grupal, consta de ocho sesiones, incluyendo psicoeducación, entrenamiento en control de la activación, terapia cognitiva y terapia de exposición. Se utilizó un diseño cuasiexperimental de medidas repetidas (en el pretratamiento, postratamiento y seguimientos a l y 3 meses). En el postratamiento y en los seguimientos se consigue une mejora significativa tanto en la sintomatología postraumática (superación del TEPT en más del 85% de las participantes) como en los problemas asociados: Depresión, autoestima, inadaptación social y cogniciones postraumá-ticas. Se comentan las implicaciones de este estudio para la práctica clínica.Palabras clave: Trastorno de estrés postraumático, mujeres maltratadas, terapia cognitiva, terapia de exposición. Evaluation of the short term effectiveness of a treatment program for the posttraumatic stress disorder in Mexican women victims of domestic violenceAbstract: The objective of this investigation is to evaluate empirically the effectiveness of a brief and specific intervention program for the treatment of post-traumatic stress disorder (PTSD) in women victims of domestic violence. The participants were 34 Mexican women battered by their partner, all with a diagnosis of PTSD (DSM-IV-RT). The treatment program was applied in groups and consists of eight sessions comprising psychoeducation, training for activation control, cognitive therapy and exposure therapy. A cuasi-experimental design of repeated measures was used (pretreatment, post-treatment and 1 and 3 months' follow-up). The results at post-treatment and both follow-ups show a significant improvement in PTSD symptoms (elimination of PTSD in 85% of participants) as well as in related symptoms: depression, self-esteem, social maladaptation and posttraumatic ideation. The implications of this study for clinical practice are commented.

The inclusion of Internet Gaming Disorder (IGD) in the DSM-5 has generated controversy over its diagnosis, and it therefore seems necessary to establish a clear cutoff point to identify when excessive gaming becomes problematic. Such identification is especially difficult in adolescents and young people, who frequently dedicate a great deal of time to online games. The goal of this systematic review was to analyze the instruments developed to assess IGD in adolescents and young people since its inclusion in the DSM-5. We identified 13 studies which included validations of seven assessment instruments for IGD in adolescents and young people. Each instrument and its validations in different languages are described. In comparison to previous reviews, a lower diversity of assessment instruments, a reduction in the number of items and a more uniform form of measurement was observed, maintaining high internal consistency and good criterion validity. However, problems related to sample selection, the lack of sensitivity and specificity studies, and the establishment of cut points and profiles of gamers remain. Advances in the analysis of the psychometric qualities of the instruments and their validation in different countries are needed, and cultural differences should be considered in order to allow the prevalence of this problem to be compared.
