This study examined the predictive value of the three dimensions of youth psychopathic personality towards delinquency, on delinquency through the application of hierarchical regression analysis, while controlling for gender. Dimensions being: Callous/Unemotional-, Impulsive/Irresponsible-, and Grandiose/Manipulative traits. The study included 891 (48% female) Swedish adolescents from a community sample with a mean age of 14.28 (SD=.94) years. A self-report instrument was used to assess psychopathic traits in youth, the Youth Psychopathic Traits Inventory (YPI), consisting of 50 items and is specifically designed to lower the risk of response bias. Results: It was discovered that Impulsivity/Irresponsible behavior predicted statistically significant 14% of the variance in delinquency, and gender significantly predicted 4%. Callous/Unemotional predicted non-significant 0,3% and Grandiose/Manipulative predicted none of the variance in delinquency and was not significant. The findings regarding dimensions contradict the majority of research on the subject which has focused on CU-traits as main predictor of antisocial behavior, but in line with recent studies using a similar analytical approach showing Impulsivity/Irresponsible behavior as main predictor. The findings regarding gender are in line with previous research.

The aim of the study was to identify the factors that have an influence on the completion rates of undergraduate students in the fields of science, technology, engineering and mathematics (STEM). Using Tinto's retention rate theory as the theoretical foundation, data were collected from freshman who were enrolled in the years 2005 to 2008. Results showed gender and first-generation status were significant predictors of STEM completion and time taken to complete the degree. Institutional bias played a role in race/ethnicity not being a factor affecting completion rates, as this study was conducted at a Predominantly White Institution. SAT scores and first and second-year college GPA showed to have the most prominent influence on both STEM completion rate and time taken to complete the degree. Females with higher first-year college GPA and higher high school rank finished faster. Similar results were found with first-generation students as well. Students belonging to ethnic minority groups with higher SAT scores and college GPA had greater success in STEM fields as well. The study results can be used to increase completion rates of underrepresented students in the STEM fields, given what we know about the interactions between underrepresented student groups and the most important predictors.

Studien undersökte förekomsten av brottsligt beteende hos ungdomar i allmänhet och hur sociala och personliga resurser kan fungera som skydds- eller riskfaktorer i synnerhet samt vilka skillnader som finns mellan flickor och pojkar. Undersökningen gjordes på 1324 ungdomar i årskurs nio genom projektet LoRDIA. Data analyserades med t-test, Spearman's korrelationsanalys och hierarkisk multipel regressionsanalys. Resultaten visade att den starkaste prediktorn för ungdomars brottsliga beteende var deras kamraters brottsliga beteende. Socialt välbefinnande visade sig vara en viktigare personlig resurs för flickorna när det handlade om att predicera brottsligt beteende. Psykologiskt välbefinnande var viktigare för pojkarna Överlag låg studiens resultat i linje med tidigare forskning. Avvikande resultat diskuterades. Undersökningen relaterades till möjlighetshorisonter och ungdomars uppfattning om vilka studie och yrkesval de stod inför. Slutligen föreslogs hur företag och branschorganisationer kan tänka och agera från studiens resultat. / The study examined the prevalence of criminal behavior among adolescents in general and how social and personal resources can act as protection or risk factors in particular and also what differences exist between girls and boys. The survey was conducted on 1324 youths in ninth grade through the LoRDIA project. Data was analyzed by t-test, Spearman's correlation analysis and hierarchical multiple regression analysis. The results showed that the strongest predictor of young people's criminal behavior was peer delinquency. Social well-being turned out to be an important personal resource for the girls when it was about predicting criminal behavior and psychological well-being was important for the boys. While overall the results were in line with previous research, some divergent results were also discussed. The study was related to horizons of opportunities and to young people's perception of the educational and career choices they faced. Finally ways for companies and organizations to think and act on the results of the study were suggested.

Contexte: L’arthrite juvénile idiopathique (AJI) est l’une des maladies chroniques auto-immune les plus répandues chez les enfants et est caractérisée par des enflures articulaires (maladie active), de la douleur, de la fatigue et des raideurs matinales pouvant restreindre leur niveau de participation aux activités quotidiennes (par exemple: les loisirs, l’activité physique, la mobilité et les soins personnels) à la maison comme à l’école. Participer aux activités de loisirs et à l’activité physique a des bienfaits au niveau de la santé et du développement de tous les enfants et démontrent aussi des effets positifs qui réduisent les symptômes des maladies chroniques telle l’AJI. Malgré ces bienfaits la participation aux loisirs chez les jeunes avec l’AJI demeure largement sous-étudiée. Objectifs: Cette étude vise à évaluer le niveau de participation aux loisirs et à l’activité physique chez les enfants et les adolescents atteints d’AJI, ainsi qu’à identifier les facteurs liés à la maladie, la personne et l’environnement. Méthodes : L’évaluation du niveau de participation et l’exploration des facteurs associés aux loisirs et à l’activité physique ont été complétés par l’entremise d’une revue systématique de la littérature, l’analyse de données d’un échantillon national représentatif d’enfants canadiens atteints d’arthrite âgés entre 5 et 14 ans (npondéré = 4350), ainsi que l’analyse standardisée du niveau de participation aux loisirs à l’aide du Children’s Assessment of Participation and Enjoyment (n=107) et la mesure objective de l’activité physique par accéléromètre (n=76) auprès d’un échantillon d’enfants (âgés entre 8 et 11 ans ) et d’adolescents (âgés entre 12 et 17 ans) suivis en clinique de rhumatologie à l’hôpital de Montréal pour enfants, Centre Universitaire de Santé McGill. Les résultats cliniques ont été comparés à des données normatives, ainsi qu’à un groupe contrôle sans AJI. Nous avons exploré les facteurs associés avec le niveau de participation aux loisirs et à l’activité physique en utilisant les modèles de régression linéaire multiple et l’analyse hiérarchique. Résultats : Les enfants et les adolescents atteints d’AJI participent à une multitude d’activités de loisirs; cependant ils sont moins souvent impliqués dans des activités physiques et de raffinement en comparaison aux autres types d’activités de loisirs. Ceux avec l’AJI étaient en général moins actifs que leurs pairs sans arthrite et la plupart n’atteignaient pas les recommandations nationales d’activité physique. Les garçons avec l’AJI participent plus souvent à des activités physiques et moins aux activités sociales, de raffinement et de développement de soi en comparaison avec les filles ayant l’AJI. En général, être un garçon, être plus âgé, avoir une meilleure motivation pour participer aux activités de motricité globale, avoir un statut socio-économique plus élevé et être d’origine culturelle canadienne sont associés à un niveau de participation plus élevé aux activités physiques. La préférence pour les activités de raffinement, un niveau d’éducation maternelle plus élevé et être une fille étaient associés à un niveau de participation plus élevé aux activités de raffinement. Conclusion: La participation aux loisirs et à l’activité physique en AJI est un concept complexe et semble surtout être expliqué par des facteurs personnels et environnementaux. L’identification des facteurs associés aux loisirs et à l’activité physique est très importante en AJI puisqu’elle peut permettre aux professionnels de la santé de développer des interventions significatives basées sur les activités préférées des enfants, améliorer l’observance au traitement et promouvoir des habitudes de vie saine. / Background: Juvenile idiopathic arthritis (JIA), one of the most common chronic childhood autoimmune diseases, is a heterogeneous inflammatory condition characterised by joint inflammation (i.e. active disease), chronic pain, fatigue and morning stiffness, which may interfere with age-appropriate daily activities (i.e. leisure and physical activity, mobility and self-care), both at home and at school. Involvement in leisure and physical activity is beneficial to the health and development of all children and adolescents, and has also shown to help mitigate the effects of disease among those with chronic conditions such as JIA. Despite the benefits of leisure participation this subject remains vastly understudied in JIA. Objective: The aim of this thesis was to assess participation in leisure and physical activity among children and adolescents with JIA, as well as identify associated disease-related, personal and environmental factors. Methods: The assessment of patterns and exploration of potential predictors of participation in leisure and physical activity in children and adolescents with JIA was completed through a systematic review of the literature, analysis of survey data from a nationally representative sample of Canadian children with arthritis (age range = 5 to 14 years, nweighted = 4350), as well as the standardized assessment of leisure with the Children’s Assessment of Participation and Enjoyment (n=107) and the objective measurement of physical activity with accelerometer (n=76) among a clinical sample of children (age range = 8 to 11 years) and adolescents (age range = 12 to 17 years) with JIA followed at the Rheumatology clinic at the Montreal Children’s Hospital, McGill University Health Center. Clinical data were also compared to normative data and children and adolescents without JIA. We explored factors associated with participation in leisure and physical activity using multiple linear regression models and hierarchical analysis. Results: Children and adolescents with JIA participated in an array of leisure activities; however involvement was least frequent in active physical and skill-based leisure activities compared to other types of activity. Those with JIA were generally less physically active than healthy peers without JIA, and most with JIA did not meet national recommendations for physical activity. Boys with JIA were more likely to engage in physical activities, and less likely to take part in social, skill-based and self-improvement activities than girls with JIA. In general, being a boy, older age, greater mastery motivation for gross motor skills, higher socio-economic status and being of Canadian cultural background were associated with increased participation in more physical activities. Preference for skill-based activities, higher maternal education and being a girl were associated with increased participation in skill-based activities. Conclusion: Participation in leisure and physical activity in JIA is a complex concept and is mostly explained by personal and environmental factors. The identification of factors associated with leisure participation and physical activity is of utmost importance in JIA as it may aid health care professionals to tailor meaningful intervention plans based on preferred activities, improve adherence to treatment and help promote healthier lifestyles.

<p>This dissertation investigated a psychoeducational intervention’s effectiveness in nurturing concern for others in adolescents with high intellectual abilities. The intervention was implemented at two research sites in a city in western India with 130 participants. Concern for others was conceptualized as an interplay of empathy, compassion, and prosocial behavior, and interrelationships among them were examined using correlational and regression analyses of self-reported survey data. Results indicated that prosocial behavior is positively associated with empathy (i.e., perspective taking and empathic concern) and other-compassion (i.e., compassion for others and compassion for other living beings) with correlations ranging from medium to strong (.46 ≤ <em>r</em> ≤ .79). Compassion for self, however, is not associated with prosocial behavior (<em>r</em> = .01) or any other key variables of having a concern for others (-.06 ≤ <em>r</em> ≤ .09). Compassion for others and perspective taking are the strongest predictors of prosocial behavior. Predicted self-reported prosocial behavior in girls is, on average, significantly greater than that in boys. Participants were then randomly assigned to treatment and control (delayed treatment) groups. The intervention’s effectiveness was evaluated using a convergent mixed-methods design by combining repeated-measures multivariate analysis of variance (RM-MANOVA) of self-reported survey data and thematic analysis of interview data. Classroom quality was perceived to be high. Moreover, on average, participants’ level of adherence to the intervention was high, especially for session attendance (93%), and self-reported home activity completion (89%). The RM-MANOVA results showed that the self-reported concern for others varied significantly over the time of participants’ participation in the intervention with a large effect (treatment group: ηp2 = .57; delayed treatment group: ηp2 = .47); however, the effects did not seem to sustain over the next three months. Univariate <em>post-hoc</em> analyses indicated significant differences with moderate effect size in prosocial behavior and compassion for others. Overall, the intervention was perceived to be a largely positive experience—appealing, meaningful, and supportive of belongingness—yet there is a scope for improvement, especially regarding active participation. Emotional regulation, mindful engagement, responsible communication, relationship building, kindness, and gratitude were described as key intervention affordances. The mixed-methods integration of results provided preliminary evidence for the effectiveness of the intervention. (IRB #1812021447)</p>
