Internet-delivered psychotherapy has been demonstrated to be effective in the treatment of depression. Nevertheless, the study of the adherence in this type of the treatment reported divergent results. The main objective of this study is to analyze predictors of adherence in a primary care Internet-based intervention for depression in Spain. A multi-center, three arm, parallel, randomized controlled trial was conducted with 194 depressive patients, who were allocated in self-guided or supported-guided intervention. Sociodemographic and clinical characteristics were gathered using a case report form. The Mini international neuropsychiatric interview diagnoses major depression. Beck Depression Inventory was used to assess depression severity. The visual analogic scale assesses the respondent's self-rated health and Short Form Health Survey was used to measure the health-related quality of life. Age results a predictor variable for both intervention groups (with and without therapist support). Perceived health is a negative predictor of adherence for the self-guided intervention when change in depression severity was included in the model. Change in depression severity results a predictor of adherence in the support-guided intervention. Our findings demonstrate that in our sample, there are differences in sociodemographic and clinical variables between active and dropout participants and we provide adherence predictors in each intervention condition of this Internet-based program for depression (self-guided and support-guided). It is important to point that further research in this area is essential to improve tailored interventions and to know specific patients groups can benefit from these interventions.

Arithmetic word problem (AWP) solving is a highly demanding task for children with learning disabilities (LD) since verbal and mathematical information have to be integrated. This study examines specifically how syntactic awareness (SA), the ability to manage the grammatical structures of language, affects AWP solving. Three groups of children in elementary education were formed: children with arithmetic learning disabilities (ALD), children with reading learning disabilities (RLD), and children with comorbid arithmetic and reading learning disabilities (ARLD). Mediation analysis confirmed that SA was a mediator variable for both groups of children with reading disabilities when solving AWPs, but not for children in the ALD group. All groups performed below the control group in the problem solving task. When SA was controlled for, semantic structure and position of the unknown set were variables that affected both groups with ALD. Specifically, children with ALD only were more affected by the place of the unknown set.

La destreza de escribir correctamente los números se adquiere en los primeros años de educación primaria. Sin embargo, existen niños a los que se les dificulta realizar el cambio del código verbal al arábigo, cometiendo errores de omisión, adición e inversión de números hasta finales de la educación primaria. El objetivo de este trabajo ha sido analizar la escritura de números de unidades, decenas y centenas en función del nivel de rendimiento en matemáticas. En este caso se encontró que la escritura de centenas es una variable capaz de discriminar a los niños con dificultades de aprendizaje en matemáticas (DAM) de otros grupos. A raíz de estos resultados, se procedió a un análisis cualitativo de los tipos de errores en escritura de centenas cometidos por los distintos grupos evidenciando una predominancia de los errores léxicos sobre los sintácticos en todos los grupos de rendimiento, específicamente se evidenció que los errores de codificación literal, inversión y omisión son más frecuentes en los grupos DAM y rendimiento bajo.
