Objectives: To evaluate the associations of physical education (PE) with school violence and bullying. Design: Systematic review. Method: Using a systematic search in Medline, PsycINFO, SPORTDiscus, Web of Science, and Scopus, relevant studies with a quantitative and qualitative design were identified that met previously established eligibility criteria. Quality was assessed (bias risk analysis) and data were extracted from a previously elaborated template. Results: The systematic review finally included 16 studies, of which 10 had a quantitative design (n = 12795), 5 a qualitative design (n = 79) and 1 a mixed design (n = 86). The high heterogeneity presented by the measures used in the included studies hindered the comparison of the outcomes and prevented meta-analysis of the data. Although there is insufficient evidence about the positive impact of PE on bullying prevention, the results of this review indicate that some aspects of PE programs could improve students’ skills to cope with these situations. Conclusions: The results of this review suggest the importance of PE in the prevention of bullying. Secondly, it is emphasized that bullying situations have a negative impact on students’ enjoyment of PE, leading to detrimental consequences for their physical and psychological health. Thirdly, the figure of the PE teacher as a key element to prevent and/or encourage bullying was obvious.

Vitamin and fatty acid deficiency in children diagnosed with autism has been linked to the etiology and course of the disease but the results have been inconsistent. In our work, we present a narrative review, which includes 20 observational studies that provide data on the blood levels of vitamin D, folate, or fatty acids of children diagnosed with ASD (Autism Spectrum Disorder—AG group), and of a control group (children without this disorder—CG group). The main characteristics and results are presented in a summary table. Of the 20 above-mentioned studies, a meta-analysis of vitamin D and folate levels was carried out in 14 of them, with a total of 2269 children (AG = 1159, CG = 1110). Vitamin D levels were lower in AG compared to CG: SMD, 95% CI = − 0.83 [− 1.15, − 0.50]. In terms of folate levels, a total of 299 children (AG = 148, CG = 151) were analyzed, finding no significant differences with the control group: SMD, 95% CI = − 0.16 [− 0.63, 0.32]. Only one study that provided data on fatty acids in children with ASD was included in the review although it was not possible to include it in the meta-analysis. We conclude that the nutritional status (vitamin and fatty acid levels) of patients diagnosed with ASD should be taken into account, as correct adjustment of these levels—may produce an improvement in the course of the disease and could also reduce the risk of its development.

Dating violence in the young adult population is reaching alarming levels. However, the instruments used to measure it and their results are still heterogeneous. The main aim of this study was to validate the Conflict in Adolescent Dating Relationships Inventory questionnaire for a young adult Spanish university population aged between 19 and 25 years old, and to describe the types of violence perpetrated and suffered. Material and Methods. Observational, descriptive, cross-sectional study. A validity analysis was carried out through a confirmatory factor analysis. The relative frequencies for each type of violence and the Chi2 test for two dichotomous variables were used to describe the different types of violence perpetrated and suffered. Results: The sample consisted of 976 young adults aged 19–25 years old (M = 21.7 years. SD = 1.8). The confirmatory factor analysis had an adequate structure and a good fit to the model. The types of violence perpetrated and suffered were described according to the sex of the participants, with significant differences found for verbal-emotional violence and physical violence exerted. Conclusions: The confirmatory factor analysis allowed us to consider the application of the questionnaire to be correct for the study population.

Externalizing Behavior Disorders are one of the most common mental health problems among adolescents, and they have a severe impact on family, school, and social settings. The purpose of this study was to compare adolescents from the general population without an externalizing behavior diagnosis with adolescents from a clinical sample in a series of variables identified as predictors of externalizing behavior. The study included adolescents aged between 12-15 years from the Region of Murcia. A cross-sectional, descriptive, analytical design was used with a sample of 327 adolescents, who were distributed as follows: (a) Clinical Group, made up of 59 participants, and (b) General Group, made up of 268 adolescents.The results of this study indicate that externalizing behavior is mainly related to Impulsivity, although modulated by factors related to the adolescent's family and cultural socialization. The adolescents of the clinical sample described the parental styles they received as more authoritarian and less inductive than those of the adolescents from the general population.

According to the World Health Organization, one out of every four violent workplace acts takes place in the health setting. The aims of the study are to adapt the Healthcare-workers’ Aggressive Behavior Scale-Users (HABS-U) to mental health professionals, to establish the frequency of exposure to hostile indicators and to determine which professional group is most exposed. Study through qualitative and quantitative methodology in MH professionals of the Region of Murcia (Spain). In the qualitative phase, 12 in-depth interviews were conducted, and during the quantitative phase, the instrument was applied to 359 professionals of Mental Health Services (MHS). Non-medical and nursing staff were found to be the professional group most exposed, as well as Brief Psychiatric Inpatient and Medium-Stay Inpatient Services. The resulting scale shows excellent psychometric properties. The distribution of user violence is not homogeneous among the different professional groups of MHS. The adaptation of the scale may be useful to detect user violence, as well as to evaluate the efficacy of intervention programs.
