Maturity-associated variation in sport-specific skills of youth soccer players aged 13 – 15 years

The aim of this study was to estimate the contribution of experience, body size and maturity status to variation in sport-specific skills of adolescent soccer players. The participants were 69 players aged 13.2?–?15.1 years from three clubs that competed in the highest division for their age group. Height and body mass were measured and stage of pubic hair development was assessed at clinical examination. Years of experience in football was obtained at interview. Six football skill tests were administered: ball control with the body, ball control with the head, dribbling with a pass, dribbling speed, shooting accuracy and passing accuracy. Multiple linear regression analysis was used to estimate the relative contributions of age, stage of sexual maturity, height, body mass and years of formal training in soccer to the six skill tests. Age, experience, body size and stage of puberty contributed significantly but in different combinations to the variance in four of the six skill tests: dribbling with a pass (21%; age, stage of maturity), ball control with the head (14%; stage of maturity, height, body height × body mass interaction), ball control with the body (13%; stage of maturity, years of training) and shooting accuracy (8%; stage of maturity, height; borderline significance, P?=?0.06). There were no significant predictors for the tests of dribbling speed and passing accuracy. In conclusion, age, experience, body size and stage of puberty contributed relatively little to variation in performance in four of the six soccer-specific skill tests in adolescent footballers aged 13?–?15 years.     

Child physical abuse – High school students’ mental health and parental relations depending on who perpetrated the abuse

The aim of this study was to contribute to the research of child physical abuse (CPA) by examining if there were any differences in high school students’ mental health (in this study symptoms of depression and anxiety, self-esteem and sense of coherence) and/or, in how they perceive their parents, depending on whether or not they had been subjected to CPA during childhood. In addition, if high school students reported different mental health and/or, relationships with their parents, depending on if their mother, father or both parents were the perpetrators of CPA.A representative national sample of high school students (N = 3288, data collected 2009) participated in the study. Participants completed the following: questions about CPA and alleged perpetrators, the Hopkins Symptom Checklist, Rosenberg Self-Esteem Scale, the Sense of Coherence Scale and Parental Bonding Instrument.The results showed students who reported experiences of CPA were more likely to report symptoms of mental illness and negative perceptions of their parents’ parenting. However, there were no mental health differences depending on whether their mother, father or both parents were the perpetrators of CPA. Still, there were differences in perceived parenting indicating that mothers’ parenting was perceived as more negative when mothers only or both parents were perpetrators of the abuse than when only fathers were perpetrators.     

One-sided and mutually aggressive couples: Differences in attachment,conflict prevalence,and coping

This study investigated concurrent links between adolescent romantic couples’ reports of aggression (relational and physical) and relationship functioning (e.g., attachment security, conflict prevalence, coping strategies, jealousy, and affiliative and romantic relationship quality) using a pattern-oriented approach. The sample included 194 romantic partner dyads (Mage = 16.99 years for females and Mage = 18.41 years for males). A hierarchical cluster analysis identified five distinct subgroups of dyads based on male and female reports of relational and physical aggression, ranging from nonaggressive couples (42%), to those characterized by aggressive females (18%), aggressive males (14%), physically aggressive females (20%), and mutually aggressive females and males (6%). Clusters in which one partner was perceived as either relationally or physically aggressive were characterized by higher rates of conflict, less adaptive coping, and more jealousy (particularly in males). The mutually aggressive couples showed the least adaptive relationship functioning, with high rates of conflict, a deficit in reflection and emotion regulation in conflict situations, and a lack of affiliative relationship qualities. The discussion focuses on the formative character of aggression in these early romantic relations, the aggravating impact of mutual aggression on relationship functioning, and the gender-specific functions of aggression in relationships characterized by unilateral aggression.     

Analysis of demographic,psychological and cultural aspects associated with the practice of sexting in Mexican and Spanish adolescents

Sexting is an increasingly frequent phenomenon among adolescents, and it involves risky behaviors such as sextortion or even grooming. This study aims to analyze demographic, psychological, and cultural variables that may explain the nature of this phenomenon. The sample consisted of 471 adolescents from 12 to 18 years old from two countries, Spain and Mexico, with dissimilar levels of gender inequality. Results highlight important differences in sexting behavior between the two countries. We have found higher levels of sexting behaviors in Mexican adolescents (41.5 %) than in Spanish adolescents (24.6 %) as well as an earlier start in Mexican adolescents. Moreover, adolescents in Mexico engage in sexting more frequently. There are no differences, however, in age showing a growing pattern in the two countries, nor in gender, self-esteem or impulsivity. These results are interpreted from a cultural perspective and highlight the importance of studying the phenomenon of sexting within the framework of cultural influences, especially sexism. Considering cultural factors is necessary, in order to implement differential preventive strategies according to each culture. Prevention in countries with high inequality, such as Mexico, should be earlier.     

When in Rome… A longitudinal investigation of the predictors and the development of student sojourners’ host cultural behavioral engagement

International educational mobility is an important instrument for immersing multicultural diversity into the thinking, feeling, and acting of young global citizens. Yet, little is known about the development of students’ host-cultural behavioral engagement during a stay abroad and the individual characteristics that predict it. We adapted the theory of planned behavior to investigate the dynamic longitudinal interplay between individual predictors and students’ host-cultural behavioral engagement over the course of the stay abroad. Data come from the first four waves of the project Mobility and acculturation experiences of students (MAPS; N = 1,225). Results confirmed the influence of acculturation attitudes, subjective norms, and multicultural self-efficacy on host-cultural behavioral engagement over time. Simultaneously, host-cultural behavioral engagement was identified as a relevant predictor of adolescents’ individual development abroad.     

There are two I’s in motivation: Interpersonal dimensions of science self-efficacy among racially diverse adolescent youth

With the increased growth of career opportunities in STEM fields, educators and policymakers have sought to better understand the nature and development of students’ motivation to pursue science academic and career pathways successfully. However, our understanding of motivational constructs such as self-efficacy has mostly been based on studies of predominantly White samples, neglecting the perspectives and experiences of students from historically marginalized groups underrepresented in STEM academic and career pathways. In the present study, we examined science motivation in six high school students of color who participated in a brief, near peer mentoring program with undergraduate mentors of color. Deductive and inductive coding of semi-structured interviews with mentees and mentors revealed that science self-efficacy not only has a salient future-oriented component, but also centers around the importance of forming and maintaining interpersonal connections with others through proxy agency and help-seeking behaviors. These data point to the utility of a sociocultural perspective in expanding our understanding of self-efficacy—and motivational processes more generally—in a way that is more inclusive of the experiences of racial and ethnic minority youth.     

The developmental trajectories of mathematics anxiety: Cognitive,personality, and environmental correlates

Students who are highly anxious about mathematics-related activities generally exhibit lower mathematics achievement and motivation compared to their less anxious counterparts. Despite negative implications of mathematics anxiety (MA) on mathematics learning, there is a paucity of research examining how MA develops over time. Using the Longitudinal Study of American Youth dataset (N = 3116), the present study investigated two main questions regarding the development of MA in secondary school: (1) Is the development of MA characterized by a heterogeneous subset of growth trajectories? (2) How are time-varying personal and environmental factors (e.g., mathematics achievement; perceptions of math teachers) related to specific MA growth trajectories? Student MA was repeatedly assessed in six annual waves spanning across middle and high school. Using growth mixture modeling, we identified four growth trajectories of MA: (1) The non-anxious group that exhibited chronically low MA; (2) The highly anxious group which displayed moderately high MA over time; (3) The resilient group that exhibited high initial MA that steadily decreased over time; and (4) The vulnerable group that reported low initial MA that drastically increased over time. In addition, significant differences in the development of mathematics achievement, personality hardiness, and perceptions of mathematics teachers were found in these four MA groups. Findings highlight heterogeneity in the development of MA, identify middle school as a critical period for MA development, and emphasize the importance of examining developmental changes in cognitive, personality, and environmental factors to help clarify distinct MA trajectories across middle and high school.     

Connectedness and suicidal ideation among adolescents involved with child welfare: A national survey

Using data from the National Survey of Child and Adolescent Well-Being, this study examined the relationship between connectedness in major social domains (i.e., caregiver, peers, deviant peers, and school) and suicidal ideation among adolescents (11–17 years old) investigated by child welfare agencies (N = 995). Weighted logistic regression models were used to evaluate the relationships between connectedness variables and suicidal ideation, after adjusting for covariates. Youths with a stronger connection to caregivers were much less likely to report suicidal ideation, whereas youths with stronger deviant peer relationships were significantly more likely to report suicidal ideation. Significant associations found between primary caregiver and deviant peer connectedness and suicidal ideation highlight the need for attentive consideration of these relationships when working with this highly vulnerable population. Identifying domain-specific connectedness factors related to suicidal ideation presents an opportunity for the development of targeted early intervention for child welfare-involved youths.     

Sexual harassment victimization in adolescence: Associations with family background

Sexual harassment has been studies as a mechanism reproducing inequality between sexes, as gender based discrimination, and more recently, as a public health problem. The role of family-related factors for subjection to sexual harassment in adolescent has been little studied. Our aim was to study the role of socio-demographic family factors and parental involvement in adolescent's persona life for experiences of sexual harassment among 14–18-year-old population girls and boys. An anonymous cross-sectional classroom survey was carried out in comprehensive and secondary schools in Finland. 90 953 boys and 91 746 girls aged 14–18 participated. Sexual harassment was elicited with five questions. Family structure, parental education, parental unemployment and parental involvement as perceived by the adolescent were elicited. The data were analyzed using cross-tabulations with chi-square statistics and logistic regressions. All types of sexual harassment experiences elicited were more common among girls than among boys. Parental unemployment, not living with both parents and low parental education were associated with higher likelihood of reporting experiences of sexual harassment, and parental involvement in the adolescent's personal life was associated with less reported sexual harassment. Parental involvement in an adolescent's life may be protective of perceived sexual harassment. Adolescents from socio-economically disadvantaged families are more vulnerable to sexual harassment than their more advantaged peers.     

Individual and familial risk and protective correlates of physical and psychological peer victimization

The purpose of this study was to explore the association between youth characteristics, parenting behavior, and family violence and risk of physical and/or psychological peer victimization using a sample of 856 adolescents aged 10–17. Additionally, we examined whether the relation between parenting behaviors and victimization was moderated by age and gender. Data for this study were drawn from the first wave of the Developmental Victimization Survey. The results revealed unique associations between youth and familial correlates and odds for experiencing physical, psychological, and both types of victimization. Gender was found to be a statistically significant moderator of the relation between parental monitoring and odds of experiencing both physical and psychological peer victimization. Implications for bully prevention and intervention are discussed.
