Adolescent Effortful Control as Moderator of Father's Psychological Control in Externalizing Problems: A Longitudinal Study.
2018
This longitudinal study investigates the moderating role of a temperamental trait, the effortful control, in the relation between father's psychological control and externalizing problems. In Wave 1, the participants included 507 adolescents attending the second classes of two public schools situated in two Italian cities; in Wave 2, 482 adolescents attending the fifth classes of high school participated again in the study. The results demonstrated a positive contribution of paternal achievement-oriented psychological control to externalizing problems and a moderator effect of effortful control in the relationship between the father's psychological control and externalizing problems. These …
Two distinct pathways for Developmental Coordination Disorder: Persistence and resolution
2003
This article describes the perceptual motor, educational and social outcome of early motor delay in a group of 17-18 year old Finnish adolescents who were originally evaluated at age 5. The study group consisted of 65 adolescents: 22 with significant motor problems (or developmental coordination disorder, DCD), 23 with minor motor problems (intermediate group) and 20 controls. The goal of this study was to reassess the results obtained when they were age 15 and to determine whether the variables used earlier could still discriminate the adolescents at age 17. The results showed that at age 17 all perceptual motor tasks differentiated the three groups. The DCD group performed less well than …
Inattentiveness, parental smoking and adolescent smoking initiation
2004
Aims To examine how adolescents’ inattentive behaviour, together with parental smoking patterns, predicts smoking initiation by age 14. Design, settings A prospective, longitudinal study: baseline at ages 11–12, follow-up at age 14. A population-based sample of Finnish twins, born 1983–1987, with parents and classroom teachers as additional informants. Two groups were formed, allocating the co-twins of each family into separate groups: the study sample and a replication sample. Participants Twin individuals (n = 4552), aged 11–12 at baseline and 14 (average 14.04 years) at follow-up. Measurements At baseline, inattentiveness was assessed with the Multidimensional Peer Nomination Invento…
Genetic and environmental factors affecting self-esteem from age 14 to 17: a longitudinal study of Finnish twins.
2007
ABSTRACTBackgroundWe analysed genetic and environmental influences on self-esteem and its stability in adolescence.MethodFinnish twins born in 1983–1987 were assessed by questionnaire at ages 14 (n=4132 twin individuals) and 17 years (n=3841 twin individuals). Self-esteem was measured using the Rosenberg global self-esteem scale and analyzed using quantitative genetic methods for twin data in the Mx statistical package.ResultsThe heritability of self-esteem was 0·62 [95% confidence interval (CI) 0·56–0·68] in 14-year-old boys and 0·40 (95% CI 0·26–0·54) in 14-year-old girls, while the corresponding estimates at age 17 were 0·48 (95% CI 0·39–0·56) and 0·29 (95% CI 0·11–0·45). Rosenberg self-…
Leisure Reading (But Not Any Kind) and Reading Comprehension Support Each Other—A Longitudinal Study Across Grades 1 and 9
2019
This study examines associations between leisure reading and reading skills in data of 2,525 students followed from age 7 to 16. As a step further from traditional cross-lagged analysis, a random intercept cross-lagged panel model was used to identify within-person associations of leisure reading (books, magazines, newspapers, and digital reading), reading fluency, and reading comprehension. In Grades 1-3 poorer comprehension and fluency predicted less leisure reading. In later grades more frequent leisure reading, particularly of books, predicted better reading comprehension. Negative associations were found between digital reading and reading skills. The findings specify earlier findings …
Low-dose vitamin D supplementation and incident frailty in older people: An eight year longitudinal study.
2018
Hypovitaminosis D is associated with frailty, but if vitamin D supplementation may prevent the onset of frailty is poorly known. Therefore, we aimed to investigate whether vitamin D supplementation is associated with a lower risk of frailty. In this longitudinal study, 4,421 individuals at high risk or having knee osteoarthritis free from frailty at baseline (mean age: 61.3, females = 58.0%) were followed for 8 years. Details regarding vitamin D supplementation were captured by asking whether the participant took vitamin D during the previous year, at least once per month. Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the presence of at least two of the followi…
Transitions in frailty phenotype states and components over 8 years: Evidence from The Irish Longitudinal Study on Ageing
2020
Abstract Aim Fried's frailty phenotype (FP) is defined by exhaustion (EX), unexplained weight loss (WL), weakness (WK), slowness (SL) and low physical activity (LA). Three or more components define the frail state, and one or two the prefrail. We described longitudinal transitions of FP states and components in The Irish Longitudinal Study on Ageing (TILDA). Methods We included participants aged ≥50 years with FP information at TILDA wave 1 (2010), who were followed-up over four longitudinal waves (2012, 2014, 2016, 2018). Next-wave transition probabilities were estimated with multi-state Markov models. Results 5683 wave 1 participants were included (2612 men and 3071 women; mean age 63.1 y…
Associations between sexual activity and weight status: Findings from the English Longitudinal Study of Ageing.
2019
Objective To investigate the association between weight status and sexual activity in middle-aged and older adults. Methods Cross-sectional analysis on Wave 6 (2012/13) of the English Longitudinal Study of Ageing. Data were from 2,200 men and 2,737 women aged ≥50 years (mean 68.2 years). The explanatory variable was weight status, defined as normal-weight (BMI: ≤24.9), overweight (BMI: 25.0–29.9) or obese (BMI: ≥30) based on objective measurements of height and weight. Outcome variables were any self-reported sexual activity in the last year (yes/no) and, if yes, frequency of sexual intercourse in the last month. Covariates included a range of sociodemographic, lifestyle, and health-related…
Antisocial and human capital pathways to socioeconomic exclusion: A 42-year prospective study.
2017
Nordic welfare states have been very successful at reducing poverty and inequality among their citizens. However, the presence of a strong social safety net in these countries has not solved the problem of socioeconomic exclusion, manifesting in such outcomes as chronic unemployment and welfare dependency. In an effort to understand this phenomenon, the current study builds on the assumption that psychological risk factors emerge as important determinants of socioeconomic disadvantage in an environment where ascribed characteristics have less impact on educational and occupational attainment. Using data from Finland, this research examined a life course model linking childhood differences i…
Neurophysiology in preschool improves behavioral prediction of reading ability throughout primary school.
2009
BACKGROUND: More struggling readers could profit from additional help at the beginning of reading acquisition if dyslexia prediction were more successful. Currently, prediction is based only on behavioral assessment of early phonological processing deficits associated with dyslexia, but it might be improved by adding brain-based measures. METHODS: In a 5-year longitudinal study of children with (n = 21) and without (n = 23) familial risk for dyslexia, we tested whether neurophysiological measures of automatic phoneme and tone deviance processing obtained in kindergarten would improve prediction of reading over behavioral measures alone. RESULTS: Together, neurophysiological and behavioral m…
