Abstract
This study aimed to use machine learning (ML) models to predict the risk of self-harm and suicide attempts in adolescents. We conducted secondary analysis of cross-sectional data from the Longitudinal Study of Australian Children dataset. Several key variables at the age of 14-15 years were used to predict self-harm or suicide attempt at 16-17 years. Random forest classification models were used to select the optimal subset of predictors and subsequently make predictions. Among 2809 participants, 296 (10.54%) reported an act of self-harm and 145 (5.16%) reported attempting suicide at least once in the past 12 months. The area under the receiver operating curve was fair for self-harm (0.7397) and suicide attempt (0.7220), which outperformed the prediction strategy solely based on prior suicide or self-harm attempt (AUC: 0.6). The most important factors identified were similar, and included depressed feelings, strengths and difficulties questionnaire scores, perceptions of self, and school- and parent-related factors. The random forest classification algorithm, an ML technique, can effectively select the optimal subset of predictors from hundreds of variables to forecast the risks of suicide and self-harm among adolescents. Further research is needed to validate the utility and scalability of ML techniques in mental health research.

Abstract
An adolescent’s knowledge of him/herself (positive aspects and weaknesses) is shaped by interactions with external and internal factors, including the family context and the educational environment. The assessment of this knowledge serves to construct the concept of self-esteem. The main objective of the present study was to examine the prevalence of self-reported emotional and behavioral symptoms in a representative sample of Italian adolescents and their relationship with gender and age, using Goodman’s Strengths and Difficulties Questionnaire (SDQ). A total of 440 adolescents (49.8% female) aged 15–18 years from the southern Italy region participated. The results show the prevalence of emotional and behavioral symptoms in the analyzed sample. Gender differences were also found in the variables under study. In conclusion, the SDQ test is offered as an agile, simplified, and effective tool, to be proposed to all formative agents who are concerned with the interest and care not only of young people, but also of the future of socio-political realities.

Abstract
Suicide rates continue to rise among children and adolescents; suicide is the second leading cause of death in the United States. Although research studies have identified factors associated with suicide risks for youths, none distinguishes those who have suicidal ideation from those who most likely will make an attempt or die by suicide. Most studies focus on psychiatric diagnoses associated with suicide risks. Recent studies suggest that cross-cutting symptom profiles may be a stronger predictor of risks for suicide than diagnosis. This article provides an overview of emotional dysregulation as it relates to suicidal ideation, intent, and behaviors for youth.

Abstract
Determining the comorbidity patterns leading to suffering behavioural eating disorders (BED) that are identifiable in the early stages of life, can help prevent their becoming chronic, as well as preventing the consequences deriving from the cost and effectiveness of intervention programs. The paper focuses mainly on analysing the association between behavioural/emotional risk factors and body image, body satisfaction and diet in school children, as well as confirming whether there are differences based on sex. Several questionnaires (Strengths and Difficulties Questionnaire and several items of Health Behaviour in School-age Children) including these variables were distributed and completed by the 647 adolescents (16 year olds on average) who took part in the research project. The findings confirmed a differentiated risk profile in adolescent girls in that they had greater prevalence of emotional symptoms as a general psychopathological trait, although this was offset with their prosocial behaviour. Additionally, the findings also allowed us to conclude that the factors that predict vulnerability to BEDs are sex, the presence of emotional symptoms and social and behavioural issues. At the end of this paper, we discuss some implications and consequences that should be taken into account for future work.

The Mediating Role of Impulsivity in the Relationship Between Suicidal Behavior and Early Traumatic Experiences in Depressed Subjects. Front Psychiatry 2020; 11:538172. [PMID: 33240115 PMCID: PMC7683571 DOI: 10.3389/fpsyt.2020.538172] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Accepted: 10/20/2020] [Indexed: 01/10/2023] Open
Abstract
Background: Depressed patients with early traumatic experiences may represent a clinically and biologically distinct subtype, with worse clinical outcomes and greater risk of suicide. Since early traumatic experiences alter development of systems that regulate the stress response, increasing sensitivity to stress and mood disorders later in life, certain personality features may influence coping strategies, putting individuals with depression and a history of early traumatic experiences at greater risk of suicidal behavior. Objective: To determine whether impulsivity mediates the relationship between early traumatic experiences and suicidal behavior in patients with major depressive disorder (MDD). Methods: The total sample consists of 190 patients [mean age (SD) = 53.71 (10.37); females: 66.3%], with current MDD (DSM-5 criteria). The Childhood Trauma Questionnaire-Short Form (CTQ-SF), the List of Threatening Experiences (LTE), and the Barratt Impulsiveness Scale-11 (BIS-11) were used to assess childhood and adulthood adverse life events and impulsivity, respectively. We developed mediation models by bootstrap sampling methods. Results: Eighty-one (42.6%) patients had a history of previous suicide attempts (SA). CTQ-SF-Total and BIS-11-Total scores were significantly higher in MDD patients with previous SA. Correlation analyses revealed significant correlations between the CTQ-SF-Total and BIS-11-Total, CTQ-SF-Total and HDRS-Total, and BIS-11-Total and HDRS-Total scores. Regression models found that CTQ-SF-Total, BIS-11-Total, and HDRS-Total scores were associated with SA. Mediation analyses further revealed the association between CTQ-SF-Total and SA was mediated by the indirect effect of the BIS-11-Total score (b = 0.007, 95% CI = 0.001, 0.015), after statistically controlling for sex, the HDRS-Total, and the LTE-Total. Discussion: Data suggest that impulsivity could mediate the influence of childhood trauma on suicidal behavior. This will help understand the role of risk factors in suicidal behavior and aid in the development of prevention interventions focused on modifiable mediators when risk factors are non-modifiable.
