Midlife Cardiovascular Status and Old Age Physical Functioning Trajectories in Older Businessmen

2019

Objectives The associations between cardiovascular disease (CVD) risk and later physical functioning have been observed, but only a few studies with follow-up into old age are available. We investigated the association between cardiovascular status in midlife and physical functioning trajectories in old age. Design Prospective cohort study. Setting Helsinki Businessmen Study. Participants We studied white men born between 1919 and 1934 in the Helsinki Businessmen Study (HBS, initial n = 3490). Measurements Three CVD status groups were formed based on clinical measurements carried out in 1974: signs of CVD (diagnosed clinically or with changes in ECG, chronic disease present or used medicati…

Barriers to outdoor physical activity and unmet physical activity need in older adults

2014

Abstract Objective To profile participants based on reported outdoor physical activity barriers using a data-driven approach, describe the profiles and study their association with unmet physical activity need. Method Cross-sectional analyses of 848 community-dwelling men and women aged 75–90 living in Central Finland in 2012. Barriers to outdoor physical activity and unmet physical activity need were enquired with a questionnaire. The latent profiles were identified by profiling participants into latent groups using a mixture modeling technique on the multivariate set of indicators of outdoor physical activity barriers. A path model was used to study the associations of the profiles with u…

Trajectories of Perceived Employability and Their Associations With Well-Being at Work

2014

The first aim of this study was to identify trajectories of perceived employability (PE) with a longitudinal person-centered approach, accounting for both the level of PE and changes in PE. The second aim was to examine how the trajectories were related to well-being at work (i.e., vigor at work, job satisfaction, and job exhaustion) with a variable-centered approach. The data were collected in two Finnish universities (N = 926) during 2008–2010 with three measurement points. Growth Mixture Modeling identified four trajectories, which differed in level, stability, and change in PE across time: we established two trajectories with stable PE (88% of the participants), and two trajectories wi…

Trajectories of change in reading self-efficacy: A longitudinal analysis of self-efficacy and its sources

2021

The beliefs children hold about their capabilities as readers are known to influence their reading achievement. The aim of this study was to extend previous work by examining trajectories of change in reading self-efficacy among primary school students (N = 1327) and the relations between the trajectories of self-efficacy and their hypothesized sources over 11 months. Using growth mixture modeling, we identified four trajectories of change in reading self-efficacy, involving increasing, stable, and declining trends. These trajectories of change in reading self-efficacy were associated with students’ varying experiences with the four sources of self-efficacy over time. Higher levels of maste…

Developmental trajectories of school burnout: Evidence from two longitudinal studies

2014

Abstract To examine school burnout trajectories, in Study 1, 15-year-old adolescents ( N  = 614) completed the School Burnout Inventory twice during their final term of comprehensive school and twice after the transition to upper secondary high school or vocational school. In Study 2, school burnout in 17-year-old adolescents was measured twice annually ( N  = 575) during their upper secondary education. In Study 1, growth mixture modeling for school burnout yielded a four-latent-group solution: 60% of the adolescents showed a low and stable level of school burnout, 29% increasing burnout, 3% strongly increasing burnout and 8% high-decreasing school burnout. In Study 2, we identified two la…

Career goal-related success expectations across two educational transitions: A seven-year longitudinal study

2013

The purpose of this seven-year longitudinal study was to examine the trajectories of adolescents' career goal-related success expectations during two educational transitions. Altogether 850 (48% female, M Age = 16) participants reported their success expectations for their career-related goals, first in the last year of comprehensive school and four times during the following seven years. Overall, the success expectations showed a significant increase. However, there was considerable heterogeneity in the development of these expectations. Growth Mixture Modeling showed that four trajectories fitted the data best: high-increasing (78%), low-increasing (9%), decreasing (6%) and U-shaped (7%).…

The effectiveness of increased support in reading and its relationship to teachers' affect and children's motivation

2016

Abstract The aims of this study were, firstly, to identify different groups of teacher–child dyads on the basis of the longitudinal associations between teachers' individual support in reading and children's reading skills, and, secondly, to examine whether the groups thus identified differ with respect to various teacher- and child-related factors. A total of 372 teacher–child dyads were examined. The reading skills of 6- to 7-year-old Finnish-speaking children were measured at the beginning and end of Grade 1. The amount of teachers' support in reading for a particular child was gathered from teachers by questionnaires. Regression Mixture Modeling identified three latent groups of teacher…

Change and stability of sense of coherence in adulthood: Longitudinal evidence from the Healthy Child study

2007

Abstract The main aim of this three-wave 35-year follow-up study among Finnish employees ( n  = 532) was to investigate whether Sense of Coherence (SOC) is more stable among those with high SOC compared to those with low SOC, as hypothesized by Antonovsky [Antonovsky, A. (1987). Unraveling the mystery of health: how people manage stress and stay well. San Francisco, CA, US: Jossey-Bass], using two measurement points over 13 years. The participants were first studied in adolescence in 1961–1963, after which they responded to two postal questionnaires measuring SOC, first in 1985, and again in 1998. The results of the Factor Mixture Modeling identified two groups of individuals with different…

Antecedents and Consequences of Student-Athletes’ Identity Profiles in Upper Secondary School

2020

The present study examined the identity profiles that upper-secondary-school Finnish student-athletes show, and the extent to which these profiles were associated with their athletic and academic achievements and withdrawal from sports and school. A total of 391 adolescent athletes (51% females) completed assessments of student and athletic identity four times during their time in upper secondary school. Using growth mixture modeling, three groups were identified: (a) dual identity (77%), (b) changing identity (5%), and (c) athletic identity (18%). The higher the academic achievement was at Time 1, the more likely the athletes were to show dual identity than athletic identity profile. Simil…
