Identity profiles and digital engagement among Finnish high school students

2018

Developing a stable personal identity is considered a more precarious task in today’s society than hitherto. Skilful digital engagement may, however, constitute a valuable asset in necessary identity exploration and commitment. Applying a person-oriented approach, we examined for the first time how identity profiles are associated with digital engagement, operationalized as digital competence, gaming seriousness, type of internet activity and excessive ICT use. After controlling for gender, life satisfaction and parental SES, this study of a Finnish high school sample (N = 932) revealed that adolescents with future commitments and some exploration of options (achievement, searching moratori…

Influential Periods in Longitudinal Clinical Cardiovascular Health Scores

2021

Abstract The prevalence of ideal cardiovascular health (CVH) among adults in the United States is low and decreases with age. Our objective was to identify specific age windows when the loss of CVH accelerates, to ascertain preventive opportunities for intervention. Data were pooled from 5 longitudinal cohorts (Project Heartbeat!, Cardiovascular Risk in Young Finns Study, The Bogalusa Heart Study, Coronary Artery Risk Development in Young Adults, Special Turku Coronary Risk Factor Intervention Project) from the United States and Finland from 1973 to 2012. Individuals with clinical CVH factors (i.e., body mass index, blood pressure, cholesterol, blood glucose) measured from ages 8 to 55 year…

Genetic and Environmental Effects on the Individual Variation and Continuity of Participation in Diverse Physical Activities

2021

INTRODUCTION Participation in diverse physical activities has beneficial health effects. However, little is known on how genetic and environmental factors affect this trait. Thus, we examined to what extent these factors explain participation in diverse leisure-time physical activities from late adolescence to adulthood using a twin study design. METHODS The participants were Finnish twins who reported their participation in diverse leisure-time physical activities at ages 17 (n = 5429) and 34 yr (n = 4246). The number of physical activities engaged in was analyzed using applications of structural linear modeling for twin data. RESULTS On average, the total number of physical activities eng…

Perceived threat and prejudice towards immigrants in Finland : A study among early, middle, and late Finnish adolescents

2017

ABSTRACTUsing integrated threat theory, this study examined how perceived threat, or fear of immigrants, manifests among early, middle, and late Finnish adolescents, and the relationship between perceived threat and prejudice among early, middle, and late adolescents. The sample consisted of 795 Finnish adolescents between 11 and 19 years of age. Realistic and symbolic threats were the most perceived threats and were more prevalent among late adolescents. There was a positive relationship between prejudice and realistic threat, and between prejudice and symbolic threat, but a negative relationship between prejudice and negative stereotyping, and this relationship remained relatively stable …

Psychosocial maladjustment in adolescence: parental socialization, self-esteem, and substance use

2018

Este estudio analiza la vulnerabilidad de los adolescentes a par- tir de la autoestima y el consumo de sustancias, y la protección o riesgo del estilo de socialización. La muestra fue de 1445 adolescentes españoles (59.4% mujeres), 600 tempranos de 12 a 15 años (41.5%) y 845 tardíos de 16 a 17 años (58.5%). Las familias se clasificaron en una de las cuatro tipo- logías: indulgente, autorizativa, autoritaria y negligente. El ajuste de los hijos se midió con autoestima (emocional, familiar y física) y consumo de sustan- cias (alcohol, tabaco, cannabis y drogas de síntesis). Los resultados mostra- ron que en la adolescencia tardía la vulnerabilidad fue mayor que en la tem- prana. Se encontró u…

2015

Recent evidence suggests a rather gradual developmental trajectory for processing vertical relational face information, lasting well into late adolescence (de Heering and Schlitz, 2012). Results from another recent study (Tanaka et al., 2014) indicate that children and young adolescents use a smaller spatial integration field for faces than do adults, which particularly affects assessment of long-range vertical relations. Here we studied sensitivity to replacement of eyes and eyebrows (F), variation of inter-eye distance (H) and eye height (V) in young adolescents (11-12 years), young (21-25 years) and middle-age adults (51-62 years). In order to provide a baseline for potential age effects…

Effects of acute bupropion administration on locomotor activity in adolescent and adult mice

2005

Responses to some psychoactive substances seem to differ between adolescents and adults. Bupropion, an antidepressant which is also used for smoking cessation, induces a dose-dependent increase in locomotor activity in adult mice, although its behavioral actions in adolescents have not been evaluated. In the present study the effects of acute bupropion administration (5, 10, 15 and 20 mg/kg) on locomotor activity were examined in early adolescent (postnatal day (pnd): 29-31 days), late adolescent (pnd: 47-49 days) and adult (pnd > 70 days) male NMRI mice, using an infrared photocell system. Locomotion was recorded for a total period of 90 min. Results indicated that there were significant d…

Genetics of Perceived Family Interaction From 12 to 17 Years of Age

2019

We analyzed how the effects of genetic and environmental factors on the perceptions of family interaction change from early to late adolescence. The data were collected by postal surveys on Finnish twins (N = 4808) at 12, 14 and 17 years of age and analyzed using genetic twin modeling. Additive genetic factors explained a modest share of the variation in perceived relational support (a2 = 0.30 in boys and 0.18 in girls) and relational tensions (a2 = 0.13 and 0.14, respectively) at 12 years of age, with the proportions becoming larger through 17 years of age (a2 = 0.53 in boys and 0.49 in girls for relational support; a2 = 0.35 in boys and 0.33 in girls for relational tensions). Simultaneous…

Genetic and environmental influences on pubertal timing assessed by height growth

2008

Secular trends towards earlier puberty, possibly caused by new environmental triggers, provide a basis for periodic evaluation of the influence and interaction of genetic and environmental effects on pubertal timing. In such studies, a practical marker that reflects timing of puberty in both genders needs to be used. We investigated genetic and environmental influences on pubertal timing by using change in the relative height between early and late adolescence (HD:SDS, height difference in standard deviations) as a new marker of pubertal timing. HD:SDS correlated well with age at peak height velocity in a population of men and women with longitudinal growth data. In 2,309 twin girls and 1,8…

When is Meaning in Life Most Beneficial to Young People? Styles of Meaning in Life and Well-Being Among Late Adolescents

2017

The purpose of this article was to investigate the relationships between different dimensions of meaning in life and subjective and psychological well-being (PWB) among late adolescents. Three hundred and eighty four Polish participants completed The Personal Meaning Profile scale, The Satisfaction With Life Scale, The Positive and Negative Affect Schedule, The PWB scale, and the Meaning in Life Questionnaire. Two studies were conducted. In Study 1, the findings revealed that personal meaning had strong relations with subjective well-being (SWB) and PWB. In addition, the dimensions of personal meaning were more strongly associated with the cognitive dimension of SWB than with PWB. In Study …
