Effects of a Serious Game for Adolescent Mental Health on Cognitive Vulnerability: Pilot Usability Study.

Adolescent mental health is of utmost importance. E-mental health interventions, and serious games in particular, are appealing to adolescents and can have beneficial effects on their mental health. A serious game aimed at improving cognitive vulnerability (ie, beliefs or attitudes), which can predispose an individual to mental health problems, can contribute to the prevention of these problems in adolescents. This study aimed to assess the feasibility of the prototype of a serious game called "Silver." The prototype of the serious game was developed using a user-centered participatory design. The prototype of Silver focused on 1 aspect of a serious game for improving cognitive vulnerability in adolescents, that is, the recognition and identification of cognitive distortions. Through the game, players were required to identify and classify the character's thoughts as helpful or unhelpful. Upon successful advancement to the next level, the task becomes more challenging, as players must also identify specific types of cognitive distortions. A pre- and posttest uncontrolled design was used to evaluate the game, with a 1-week intervention phase in which participants were asked to play the game. Participants aged 12-16 years were recruited in schools. The outcomes of interest were the recognition of cognitive distortions and presence of participants' cognitive distortions. The game was also evaluated on its effects, content, and usefulness. A total of 630 adolescents played Silver and completed the assessments. Adolescents were significantly better at recognizing cognitive distortions at the pretest (mean 13.09, SD 4.08) compared to the posttest (mean 13.82, SD 5.09; t629=-4.00, P<.001). Furthermore, their cognitive distortions decreased significantly at the posttest (mean 38.73, SD 12.79) compared to the pretest (mean 41.43, SD 10.90; t629=7.98, P<.001). Participants also indicated that the game helped them recognize cognitive distortions. Many participants considered the game appealing (294/610, 48.2%) but boring (317/610, 52%) and preferred a more comprehensive game (299/610, 49%). Findings from this study suggest that a serious game may be an effective tool for improving cognitive vulnerability in adolescents. The development of such a serious game, based on the prototype, is recommended. It may be an important and innovative tool for the universal prevention of mental health problems in adolescents. Future research on the effects of the game is warranted.

Neighborhood material versus social deprivation in Canada: different patterns of associations with child and adolescent mental health problems.

In a nationwide study, we aimed to study the association of neighborhood deprivation with child and adolescent mental health problems. We used data from the Canadian Health Survey on Children and Youth (N = 47,871; age range: 1-17years) and linked these to Neighborhood Material and Social Deprivation data calculated using Canada's Census of Population. Using a series of logistic regressions, we studied the association between living in deprived areas and mental health problems among children and youth. We used bootstrap replicate weights for all analyses and adjusted them for individual sociodemographic characteristics. In the adjusted model, the parent-reported developmental disorder was associated with more socially deprived neighborhoods (OR 1.29; 95% CI 1.07, 1.57 for most vs. least deprived quintiles). However, mental health service need or use was associated with living in less materially deprived areas (OR 0.78; 95% CI 0.63, 0.96 for most vs. least deprived quintiles). Among mental health problemsreported by the youth (12-17years old), poor/fair general mental health, alcohol drinking, and cannabis use were associated with neighborhood social deprivation in the adjusted models. In contrast, poor/fair general mental health, suicide ideas, alcohol drinking, and cannabis use were all negatively associated with higher materially deprived quintiles. Our study provides further support for the existing evidence on the association between neighborhood deprivation, particularly social deprivation, and the mental health of children and adolescents. The findings can help public health policymakers and service providers better understand and address children's mental health needs in their neighborhoods.

Art Education as a Healing Method Helps Sensitive Teenagers Grow up in Modern Chinese Family Education

With the Chinese society&amp;#39;s emphasis on education, adolescent mental health problems have become increasingly prominent. Especially in the high-pressure family education environment, the emotional needs and psychological difficulties of highly sensitive adolescents are more prominent. This study not only focuses on the mental health of adolescents, but also aims to provide a new solution for family education and adolescent mental health through the unique perspective of art therapy. Art therapy integrates art and emotional connection to help promote the spiritual recovery of the individual. By exploring the restorative role of art in modern Chinese family education, we expect to provide new educational ideas for parents and educators, and promote the comprehensive and healthy development of adolescents.

Unraveling the core symptoms of mental health in senior grade three students- a network analysis.

Adolescence is not only an important transitional period of many developmental challenges, but also a high risk period for mental health problems. Psychotherapy is recommended for mental health problems in adolescents, but its effectiveness is not always satisfactory. One possible contributing factor may be the lack of clarity surrounding core symptoms. In this study, we investigated the mental health status of senior grade three students, a group of adolescents facing college entrance exams, by the Middle School Student Mental Health Test (MHT) and analyzed the core symptoms by network analysis. This study was conducted through an online survey platform (www.xiaodongai.com) from 15 February 2023 to 28 March 2024. The subjects scanned a QR code with their mobile phone to receive the questionnaire. The mean age of these 625 students were 18.11 ± 2.90 years. There are 238 male participants and 387 female participants. 107 individuals scored above 56 (107/461, 23.2%), with individual scale scores over 8 up to over 60% of participating students. Notably, the top three prominent symptoms were "academic anxiety", "allergic tendency" and "somatic symptoms". However, upon conducting network analysis, it became evident that three strongest edges in this network were "somatic symptoms" and "impulsive tendency", "academic anxiety" and "social anxiety" as well as "social anxiety" and "Loneliness tendency". "somatic symptoms", "social anxiety" and "self-blame tendency" exerted the highest expected influence. This suggests that, statistically speaking, these three symptoms exhibited the strongest interconnections within the network. Cross-sectional analysis; Bias in self-reported variables. These findings can deepen the knowledge of mental health among senior grade three students and provide some implications (i.e., targeting symptoms having highest expected influence) for clinical prevention and intervention to address the mental health needs of this particular group.

Perceived causal symptom network of adolescent mental health issues

Adolescent mental health is difficult to capture in categories such as depression or specific anxiety disorders. An alternative is to approach psychiatric symptoms as causal networks, potentially revealing feedback loops that maintain a pathological state. One approach to creating such networks, implemented in the PECAN methodology, is to ask adolescents about their perceptions of the causes to their symptoms. For this purpose, a transdiagnostic item list was created, and adolescents who screened positive for depression (N = 55) completed twice in two weeks a survey quantifying perceptions of causality between their mental health problems. A network that was averaged across all participants was reliable and revealed three strong feedback loops: a first loop running through stress, insomnia, fatigue, procrastination, and back to stress; a second loop between stress and overthinking; and a third loop between stress and procrastination. Although all adolescents in the study screened positive for depression, symptoms of depression were not particularly central to the network. Instead, the most central symptoms were procrastination and overthinking. The average test-retest reliability for individual networks was low, limiting clinical application. In conclusion, PECAN was found to be reliable and useful when creating a group-level network of adolescent mental health problems. While informative at a group level, the method should be improved before it can be used to inform treatment at the individual level.

The Relative Frequency of Anxiety and Its Correlation with Individual and Family Factors Among Adolescents in Shiraz, 2020: A Cross-Sectional Study

Background: Anxiety disorders are the most common mental health problems in adolescents. Uncontrolled anxiety disorders during this period not only negatively affect adolescents' current performance but can also have long-term negative consequences on their physical and mental health. Objectives: This study is designed to investigate the relative frequency of anxiety and its correlation with individual and family characteristics among first-grade high school students in Shiraz, 2020. Methods: This is a descriptive and analytical cross-sectional study, conducted on 360 first-grade high school students who were selected using a multi-stage sampling method in Shiraz, Iran. Data were collected through online questionnaire software, which included the Beck Anxiety Inventory and a Demographic Questionnaire, and were analyzed using SPSS software version 24. Results: The relative frequency of anxiety disorders in the study samples was 59.7% (60.9% in girls and 56.6% in boys); among them, 13.1% experienced severe anxiety, 16.9% had moderate anxiety, and 29.7% had mild anxiety. The results of univariate analysis showed correlations between anxiety disorders and factors such as father's unemployment (P = 0.04), a history of physical and mental problems in teenagers (P = 0.04 and P = 0.001, respectively), and the lack of friendly relations between family members (P = 0.001). Additionally, the results of logistic regression analysis indicated that adolescents with mental illness and those lacking friendly relationships within their family had higher chances of experiencing anxiety disorders compared to other participants (OR = 5.00, P = 0.04 and OR = 9.95, P = 0.002, respectively). Conclusions: In this study, mental illness and the lack of friendly relations between family members emerged as significant factors contributing to adolescents' anxiety. Therefore, identifying and addressing these related factors, along with timely diagnosis and treatment of this disorder in adolescents, should be prioritized by mental health officials.

A case study in developmental discontinuity: PROSPER Interventions and adolescent substance use trajectories shape young adult substance use and mental health problems.

The loss of John Schulenberg reverberates across the developmental and prevention sciences. In honor of his many contributions, this paper applies his ideas of developmental continuity and discontinuity to understand the process by which PROSPER delivered universal prevention programs (delivered in Grades 6 and 7) affect young adult outcomes. Guided by these developmental models, we deconstructed adolescent substance use initiation trajectories into two discrete phases-early and late adolescence, demarcated by substance use initiation levels at the end of 9th grade. We evaluated the effects of PROSPER interventions on these phases, and in turn, the effects of adolescent substance use initiation on young adult antisocial behavior, alcohol and drug use consequences, and depression symptoms. This sample included 1,984 young adults who participated in the PROSPER intervention trial in Grade 6 (two cohorts, 2002 and 2003), followed over 8 adolescent measurement occasions (Fall and Spring of Grade 6; Spring of Grades 7-12). Young adult outcomes were averaged across three waves (collected at ages 20, 23, and 25). PROSPER interventions were associated with reduced substance use initiation in early adolescence, but not escalation during late adolescence. In turn, substance use in both early and late adolescence was uniquely associated with young adult antisocial behavior, depression symptoms, and substance use consequences. PROSPER interventions were associated with young adult antisocial behavior and problematic substance use via reduced risk for early initiation status. Findings are discussed in terms of developmental continuity and discontinuity.

Secular trends in risk factors for adolescent anxiety and depression symptoms: the Young-HUNT studies 1995-2019, Norway.

In recent decades, increases in mental health problems in adolescents have been reported from several large population-based surveys. This raises questions about changes in underlying risk and protective factors that can inform future intervention strategies. Population data were collected from 1995 to 2019 in three waves of the Young-HUNT studies in Norway to map decennial trends in the prevalence of established risk factors for, and their associations with, adolescent mental health problems. All adolescents (aged 13-19years) attending lower and upper secondary school in the county of Trøndelag were invited, representing three historical cohorts of 25,245 unique adolescents. Mental health problems (HSCL-5) and established mental health risk factors were self-reported. Using a generalized linear model and linear regression, we calculated changes in relative and absolute differences between risk factors and mental health problems. Overall, the prevalence of established risk factors for mental health problems in adolescence increased markedly between 1995 and 2019, especially in girls. Prominent increases were observed for fatigue, bullying, musculoskeletal pain and migraine, loneliness, and overweight. Furthermore, with the exception of excess alcohol use and family economy, associations between each risk factor and adolescent mental health problems strengthened over the same time span in girls, but less among boys. Our findings suggest that several modifiable risk factors for poor mental health in adolescence are increasing, especially among girls, and should be targeted in community, school, and in clinical settings.

IJCM_341A: Prevalence Of Depression And Anxiety Among High School Adolescents Of Urban Area, Belagavi - A Cross Sectional Study

Background: Adolescence, which lasts from the ages of 10-19, is the stage of life between childhood and adulthood. Health issues like alcohol and drug use, poor nutrition, and physical inactivity are widespread among adolescents. Notably, mental health stands out as one of the most prevalent and significant concerns in this age group. Schools are beneficial in recognizing the mental health care needs of adolescents, given that a substantial amount of their time is spent at school. Hence the study was conducted in school to investigate prevalence of depression and anxiety among adolescent students. Objective: To assess the prevalence of depression and anxiety among high school adolescents and to know the determinants associated with it. Methodology: A cross-sectional study was carried out among high school adolescent students of schools in urban area of Belagavi. After getting approval from IEC, the data was collected from 100 students using pre-designed, pretested questionnaire. And Depression and Anxiety were assessed using the Becks Depression Inventory (BDI) scale and Hamilton Anxiety Rating Scale (HAM-A) respectively. Results: Depression prevalence was 45% among students, categorized as mild (23%), borderline (9%), moderate (8%), and severe (5%) based on Becks Depression Inventory. Mean BDI score was 11.31±8.40. Surprisingly, 97% had anxiety with 76% mild, 17% moderate,4% severe anxiety as per Hamilton Anxiety Rating Scale, with mean HAM-A score of 10.72±8.18. Most affected students were 16 years old, Class-2 socioeconomic status, Hindus, from nuclear families, residing in pucca houses, consuming mixed diet, facing learning difficulties and lacking relationship affairs. A statistically significant association existed between depression and house type, as well as history of child abuse (p&lt;0.05). Conclusion: Almost half of high school students experience varying mental health issues. Supported counseling centers in schools, implementing periodic screening, and integrating mental health education into routine activities are crucial recommendations for reducing adolescent mental health problems.

Network analysis of maternal parenting practices and adolescent mental health problems: a longitudinal study

BackgroundAn extensive literature has shown a strong connection between maternal parenting practices and adolescent mental health problems. However, it has been difficult for previous research to map a dynamic concurrent and prospective relationships within and between types of parenting practices and adolescent mental health problems. The present study addressed these issues using a network analysis approach and a longitudinal design.MethodsThis study involved 591 Chinese adolescents (249 males; mean age at T1 = 13.53) and their mothers (mean age at T1 = 39.71) at two time points (T1 and T2) with eighteen months apart. Mothers reported their parenting practices including warmth, monitoring, inductive reasoning, hostility, and harshness, while adolescents reported their mental health problems including anxiety, depression, aggression, and conduct problems. Network analysis was conducted for contemporaneous networks at T1 and T2 and temporal networks from T1 to T2.ResultsThe contemporaneous networks revealed the negative association between monitoring and conduct problems served as the main pathway through which parenting practices and adolescent mental health mutually influenced each other, and further, warmth was the most influential parenting practice on adolescent mental health. The temporal network revealed that maternal hostility exerted the most influence on adolescent mental health problems, whereas adolescents’ depression was most influenced by maternal parenting practices. Moreover, maternal hostility was most predicted by maternal harshness.ConclusionsThis study presents a novel perspective to gain a better understanding of the dynamics between and within maternal parenting practices and adolescent mental health problems. Findings highlight maternal harshness and warmth as potential prevention and intervention targets for adolescent mental health problems.

Childhood adversity and psychopathology: the dimensions of timing, type and chronicity in a population-based sample of high-risk adolescents.

Research on childhood adversity and psychopathology has begun investigating the dimension of timing, however the results have been contradictory depending on the study population, outcome and how adverse life events (ALEs) were operationalized. Additionally, studies so far typically focus only on a narrow range of psychiatric diagnoses or symptoms. The current cross-sectional study aimed to examine the association between timing, type and chronicity of ALEs and adolescent mental health problems. Adolescents from a population-based cohort oversampled on emotional and behavioral problems (mean age 14.8; range 12-17, N = 861) were included in the current analysis. Primary caregivers were interviewed on what ALEs adolescents experienced. ALEs were defined in two ways: (1) broad operationalization, including school difficulties, parental divorce, and family sickness; and (2) physically threatening abuse only, including physical and sexual violence. After looking at lifetime ALEs, we turned to chronicity, timing and sex differences. We focused on overall psychiatric symptoms as well as specific domains of emotional and behavioral problems, assessed using the Youth Self Report (YSR) and psychotic experiences assessed using the Prodromal Questionnaire-16 (PQ-16). A series of linear models adjusted for sociodemographic and parental factors were used. Lifetime ALEs were associated with all types of psychopathology, with relatively bigger effect sizes for broad than for physical ALEs. The latter associations were found to be more robust to unmeasured confounding. The 9-12 age period of experiencing both broad and physical ALE's was most saliently associated with any psychopathology. Girls were more at risk after experiencing any ALEs, especially if the adversity was chronic or ALEs took place after the age of 12. Broad as well as physical ALEs are associated with psychopathology, especially ALEs experienced during the 9-12 age period. Physical ALEs may be more useful in investigating specific etiological factors than broad ALEs. Sex differences may not emerge in lifetime measures of ALEs, but can be important for chronic and later childhood adversity.

Negative life events and their association with anxiety in adolescents with subthreshold depression

Subthreshold depression (SD) is a serious mental health problem in adolescents, and there is increasing evidence that depressive symptoms frequently occur alongside anxiety. Despite this, the extent to which negative life events (NLEs) are an associated factor in adolescents with SD comorbid with anxiety remains unclear. A total of 371 Chinese adolescents with SD were recruited (204 girls, 166 boys and missing data), ranging in age from 14 to 19 years (M = 16.34, SD = 0.96). All subjects were rated on the Centre for Epidemiological Studies Depression Scale (CES-D), the Multidimensional Anxiety Scale for Children (MASC), the Individualism-Collectivism Scale (ICS), the Adolescent Life Events Questionnaire (ALEQ), and the Neuroticism Extraversion-Openness Five-Factor Inventory (NEO-FFI-N). The SD adolescents with higher anxiety had higher neuroticism scores, more self-reported negative life events and vertical individual orientation than those with low anxiety, and more of them were female than male (all p < 0.05). Further logistic regression indicated that gender, severity of depressive symptoms, vertical individualism orientation, and neuroticism were significantly associated with anxiety symptoms (p < 0.05). Our cross-sectional study could not explain the causal relationship between the severity of individual anxiety and risk factors in SD adolescents. Our results suggest that SD adolescents with high anxiety are more likely to experience NLEs than SD adolescents with low anxiety. Gender, severity of symptoms, vertical individualism orientation, and neuroticism are independent risk factors for anxiety in SD adolescents.

A Cross-Sectional Analysis of Parental Behavior and Adolescent Mental Health in Mexico: Insights into Excessive Alcohol Intake, Tobacco Use, Suicidal Behavior, and Depressive Symptomatology.

Depression, suicidal behavior, excessive alcohol intake, and tobacco use are the main mental health problems in adolescents. To address these problems, it is necessary to understand the many factors associated with them, including parental factors. The aim of this study was to assess the associations between parental behavior and mental health problems in adolescents in Mexico. Data from the National Health and Nutrition Survey (ENSANUT) 2018-2019, representative for Mexico, were used. Households in which a parent-adolescent child pairing was identified (regardless of family type) were selected; n = 8758 households. The four outcomes of interest that were measured in the adolescents were: excessive alcohol intake, tobacco use, suicidal behavior, and depressive symptomatology. Logistic regression models using the adjusted odds ratio (AOR) and 95% confidence interval (95% CI) were estimated. Adolescents whose parents used alcohol or tobacco and reported depressive symptoms and suicidal behavior were more likely to present these behaviors themselves (AOR = 1.47, 95% CI: 1.17-1.85; AOR = 2.26, 95% CI: 1.51-3.39; AOR = 2.61, 95% CI: 1.88-3.61; AOR = 1.74, 95% CI: 1.16-2.61, respectively). Child sexual abuse was also strongly associated with the four outcomes of interest in adolescents (AOR = 1.89, 95% CI: 1.06-3.36 for excessive alcohol intake; AOR = 2.97, 95% CI: 1.49-5.91 for tobacco use; AOR = 5.15, 95% CI: 3.27-8.09 for depressive symptoms; AOR = 6.71, 95% CI: 4.25-10.59 for suicidal behavior). The family constitutes the central nucleus of care for children and adolescents; therefore, any effort to promote adolescent mental health must necessarily involve their parents and family.

This community service aims to prevent mental health problems in adolescents by providing adolescent cadres with stress management training, recognizing mental health problems, and providing mental health cadre training to adolescents. This community service was carried out through the observation, problem formulation, preparation, implementation, and evaluation stages. The method of implementing this service used training, discussion, and simulation. The evaluation instrument used was a pre-test and post-test. Data analysis used the Wilcoxon statistical test because the data was not normally distributed. The results showed % increase in knowledge among teenage cadres who had been trained by 25%. It also showed the influence of providing youth mental health cadre training on cadre knowledge (p-value=0.000 &lt;0.05). There was a need to strengthen knowledge through outreach activities and training for cadres who have been trained continuously.

Strict regulations on energy drinks to protect Minors' health in Europe – It is never too late to set things right at home

The consumption of energy drinks poses significant risks to minors' health, and strict regulations are urgently needed to protect them. The high caffeine, high sugar, and high caloric content of energy drinks have drawn concern from health professionals. The consumption of energy drinks has been linked to unhealthy dietary behaviors, obesity, and mental health problems in adolescents. The psychoactive and stimulant effects of energy drinks are particularly worrisome, and the marketing of these drinks on social media platforms is also a cause for alarm. In light of these concerns, we strongly recommend policy measures, such as restrictions on the sale of energy drinks to minors, to prevent their health risks. The evidence clearly suggests that energy drinks pose significant risks to minors' health and well-being, and regulatory standards must be implemented without further delay.

Building resilience: Key to protecting adolescent mental health

Building resilience: Key to protecting adolescent mental health Essi Viding, Pasco Fearon, Tom Wu, Alexander Lloyd, Laura Lucas, Roslyn Law, and Jaime Smith discuss new approaches to preventing adolescent mental health problems from emerging. Adolescence is a period of heightened vulnerability to developing mental health problems. Rates of mental health disorder among adolescents have increased in the last decade(1). In light of the vast associated interpersonal and economic costs(2,3) , it is striking how few resources have been invested in advancing our understanding of how to effectively prevent mental health problems developing before they become entrenched, particularly in adolescents who are at high risk.

An integrated model: marital effect on adolescent behavioral problems through siblings.

Few studies have simultaneously focused on the effects of marital conflict and marital intimacy on adolescent development, and little is known about the role of sibling relationships. Thus, this study examined the association between marital relationships and adolescent behavioral problems, including depressive symptoms and aggressive behavior. At the same time, we explored the mediating role of sibling hostility and sibling affection and the moderating effect of birth order in multichild families in China. Participants included 842 adolescents (Mage = 12.60, 46.2% boys) from Henan Province. Marital relationship, sibling relationship, birth order, depressive symptoms and aggressive behavior were assessed by a self-administered questionnaire. SEM was then used to examine the role of sibling relationships and birth order in the association between marital relationship and adolescent behavioral problems. Our results showed that marital intimacy was negatively correlated with depressive symptoms and aggressive behavior, while marital conflict was positively correlated with them. Marital intimacy was associated with depressive symptoms and aggressive behavior through both sibling hostility and sibling affection. Marital conflict was indirectly associated with depressive symptoms and aggressive behavior through sibling hostility. In addition, the first-born adolescents were more sensitive to marital intimacy. Given that the occurrence of adolescent behavioral problems is more common in contemporary society, our findings suggest that establishing a more intimate and warmer family atmosphere and promoting positive interactions between siblings may help control adolescent mental health problems.

COVID-19 pandemic impact on adolescent mental health: a reassessment accounting for development.

Current prospective reports suggest a pandemic-related increase in adolescent mental health problems. We examine whether age-related change over 11-14years accounts for this increase. Mothers and adolescents in a UK-based birth cohort (Wirral Child Health and Development Study; WCHADS; N = 737) reported on adolescent depression and behavioural problems pre-pandemic (December 2019-March 2020), mid-pandemic (June 2020-March 2021) and late pandemic (July 2021-March 2022). Analysis used repeated measures models for over-dispersed Poisson counts with an adolescent-specific intercept with age as a time-varying covariate. Maturational curves for girls, but not for boys, showed a significant increase in self-reported depression symptoms over ages 11-14years. Behavioural problems decreased for both. After adjusting for age-related change, girls' depression increased by only 13% at mid-pandemic and returned to near pre-pandemic level at late pandemic (mid versus late -12%), whereas boys' depression increased by 31% and remained elevated (mid versus late 1%). Age-adjusted behavioural problems increased for both (girls 40%, boys 41%) and worsened from mid- to late pandemic (girls 33%, boys 18%). Initial reports of a pandemic-related increase in depression in young adolescent girls could be explained by a natural maturational rise. In contrast, maturational decreases in boys' depression and both boys' and girls' behavioural problems may mask an effect of the pandemic.
