Purpose: Adolescents are particularly vulnerable to suicide attempts, which is a major risk factor for completed suicide in this age group. However, most research on suicide prevention interventions comes from high-income countries with predominantly white participants and English protocols. This study examines interventions that have been tested in Latin America and Spain. Methods: A systematic review was conducted to include interventions aimed at reducing suicide ideation, attempts, and increasing knowledge about it in these regions. Results: Sixteen articles were selected, and Dialectical Behaviour Therapy, Problem Solving Therapy, and Trauma-Focused Cognitive Behavioural Therapy were found to be more effective than standard treatments or wait-list conditions in reducing the outcomes. Discussion: This review highlights the need for more research on preventive interventions in Latin America and Spain. While all interventions evaluated were effective, further research and replication studies are necessary to strengthen the evidence base for these interventions. [ABSTRACT FROM AUTHOR]

Textbooks are frequently used as a resource to teach children how to solve word problems in mathematics classes. The solving models explicitly proposed by textbooks, and the kind of problems they propose, can therefore have a decisive influence on the way in which students learn to solve them. This paper analyses the extent to which the problem solving models proposed by the books include reasoning as one of the steps needed to solve a problem. To do this, the processes and steps articulated in the models proposed in the books by Anaya, SM and Santillana are categorized according to data, reasoning, choice of operation, strategies, execution of operations, expression of results, checking and inventing. The results indicate that reasoning processes are hardly ever found in the models, especially in lower year courses. It is concluded that mathematical textbooks provide incomplete solving models that fail to promote reasoning. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
