Sport burnout inventory–Dual career form for student-athletes: Assessing validity and reliability in a Finnish sample of adolescent athletes
2020
Background: The pressure of pursuing an athletic career simultaneously with education may set adolescent student-athletes at risk for sport and school burnout. Although the 2 life domains of student-athletes are strongly intertwined, so far, there has not been an instrument for investigating sport burnout parallel to school burnout. The aim of the present study was to introduce a sport burnout measure for adolescents in a dual career context and investigate its validity and reliability by using confirmatory factor analysis. Methods: The participants were 391 student-athletes (51% females) who filled in a questionnaire of sport burnout and background variables in the beginning of upper secon…
Genetic Influences on Alcohol Use Behaviors Have Diverging Developmental Trajectories: A Prospective Study Among Male and Female Twins
2014
Background Both alcohol-specific genetic factors and genetic factors related to externalizing behavior influence problematic alcohol use. Little is known, however, about the etiologic role of these 2 components of genetic risk on alcohol-related behaviors across development. Prior studies conducted in a male cohort of twins suggest that externalizing genetic factors are important for predicting heavy alcohol use in adolescence, whereas alcohol-specific genetic factors increase in importance during the transition to adulthood. In this report, we studied twin brothers and sisters and brother–sister twin pairs to examine such developmental trajectories and investigate whether sex and cotwin se…
Pressure to drink but not to smoke: Disentangling selection and socialization in adolescent peer networks and peer groups
2010
Contains fulltext : 90699.pdf (Publisher’s version ) (Closed access) This paper examined the relative influence of selection and socialization on alcohol and tobacco use in adolescent peer networks and peer groups. The sample included 1419 Finnish secondary education students (690 males and 729 females, mean age 16 years at the outset) from nine schools. Participants identified three school friends and described their alcohol and tobacco use on two occasions one year apart. Actor-based models simultaneously examined changes in peer network ties and changes in individual behaviors for all participants within each school. Multi-level analyses examined changes in individual behaviors for adole…
Linguistic relevance of duration within the native language determines the accuracy of speech-sound duration processing.
2003
As indexed by electrophysiological measures, in native speakers of a language with linguistically significant opposition between short and long phonemes, the pre-attentive detection accuracy of duration changes in speech sounds was tuned in comparison with that in non-speech sounds. This was not observed in advanced second-language users of the same language, suggesting that second-language acquisition does not lead to speech-specific tuning of the duration processing as does native language acquisition in early childhood.
Genetic and environmental effects on body mass index during adolescence: a prospective study among Finnish twins
2009
To study genetic and environmental factors affecting body mass index (BMI) and BMI phenotypic correlations across adolescence. Prospective, population-based, twin cohort study. We used twin modeling in 2413 monozygotic and same-sex and opposite-sex dizygotic Finnish twin pairs born in 1983–1987 and assessed using self-report questionnaires at 11–12, 14 and 17 years of age. Heritability of BMI was estimated to be 0.58–0.69 among 11–12- and 14-year-old boys and girls, 0.83 among 17-year-old boys and 0.74 among 17-year-old girls. Common environmental effects shared by siblings were 0.15–0.24 among 11–12- and 14-year-old boys and girls but no longer discernible at 17 years of age. Unique enviro…
Does health literacy explain the link between structural stratifiers and adolescent health?
2019
Abstract Background The concept of health literacy (HL) may help us to better understand the mechanisms leading to health disparities, and to focus on the factors that can be influenced. However, not much is yet known about how HL is related to health disparities, or whether the association exists among adolescents. The aim of the study was to examine the associations between structural stratifiers, HL and health indicators among adolescents. Methods The nationally representative Finnish Health Behaviour in School-aged Children survey data (n=3833) were collected from 13- and 15-year-old pupils in the spring of 2014. Pearson correlation coefficients were calculated, and separate path models…
Physical Fitness and Hormonal Profile During an 11-Week Paratroop Training Period.
2015
Physical fitness and serum hormone concentrations have been shown to change during military training. The purpose was to examine these chronic changes in paratroopers (n = 52 male conscripts) during an 11-week training period, including acute changes induced by strenuous 5-day military field training. Hormonal profiles, body mass, maximal strength, muscle endurance, and 12-minute running test were assessed at several time points during paratrooper training. In the latter part of the training period, conscripts were involved in strenuous military field training (5 days). At week 7, during specialized military training period, aerobic performance decreased (3,146 ± 163 m) but recovered back t…
Use of the Perceived Physical Competence Scale with Adolescents with Disabilities
1995
The construct validity and reliability of the 1987 Perceived Physical Competence Scale of Lintunen were examined to assess the applicability of the instrument for use with adolescents with disabilities. Subjects were 51 girls and 34 boys ( M age = 15.1 yr.) from several schools in central Finland. Principal component factor analysis with varimax rotation yielded the same two factors for adolescents with disabilities as reported for nondisabled adolescents in the related literature. Cronbach alphas for the two factors were .89 and .56. It was concluded that the scale is an appropriate measure for adolescents with disabilities. Statistical analysis indicated no gender differences for adolesc…
Adolescents' knowledge and attitudes concerning HIV infection and HIV-infected persons: how a survey and focus group discussions are suited for resea…
1999
The purpose of this article is to examine how two different corpora of material are suited for researching the sexuality of youth on the basis of material gathered via a structured questionnaire (N = 1183 response rate 87%) and via eight focus group discussions (FGDs) and to investigate the knowledge and opinions of adolescents at the age of 15 years about HIV infection and HIV-infected persons. Both boys and girls showed a good level of knowledge about HIV infection and AIDS. While their level of knowledge was good their attitude was that the threat of an HIV infection was not a personal issue. Furthermore negative attitudes to those having HIV/AIDS became more pronounced the more socially…
Cross-country comparisons of trends in adolescent psychosomatic symptoms : a Rasch analysis of HBSC data from four Nordic countries
2018
BACKGROUND: To analyse the psychometric properties of the HBSC Symptom Checklist (HBSC-SCL) on psychosomatic symptoms with a focus on the operating characteristics of the items, and on the impacts of measurement distortions on the comparisons of person measures across time and between countries.METHODS: Data were collected in 1993/94, 1997/98, 2001/02, 2005/06, 2008/09, 2013/14 in Denmark, Finland, Norway and Sweden as part of the Health Behaviour in School-aged Children (HBSC) study. Data comprised 116,531 students 11, 13 and 15 years old. Rasch analysis was conducted of the HBSC-SCL consisting of eight items with a focus on Differential Item Functioning (DIF) and item threshold ordering. …
