Work strain in midlife and 28-year work ability trajectories

2011

We investigated the 28-year development trajectories of work ability among initially middle-aged male and female municipal employees and the association of perceived mental and physical work strain in midlife by work ability trajectory groups.The baseline data of the Finnish longitudinal study of municipal employees (FLAME) were collected in 1981 (N=6257) with follow-ups in 1985, 1992, 1997, and 2009. Work ability was assessed in all the waves as present perceived work ability relative to lifetime best. Altogether, N=2690 had work ability data in 1981 and 2009, and at least for one wave in between these years, and were included in group-based semi-parametric mixture modeling trajectory anal…

Do low burnout and high work engagement always go hand in hand? Investigation of the energy and identification dimensions in longitudinal data

2011

The aim of the present 2-year follow-up study among young managers (N=433) was to investigate the intraindividual developmental patterns of burnout and work engagement as well as their interconnections. More specifically, we examined the interconnectedness of the varying patterns (i.e., latent classes) of exhaustion and vigor (i.e., the energy dimension) and cynicism and dedication (i.e., the identification dimension) across time. The latent class solutions supported by the growth mixture modeling indicated four latent classes for exhaustion and five for vigor. In addition, four latent classes were found for cynicism and six for dedication. Cynicism and dedication represented opposites with…

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…

Is Autonomy Always Beneficial for Work Engagement? A Six-year Four-Wave Follow-Up Study.

2021

Work engagement is expected to result from job resources such as autonomy. However, previous results have yielded that the autonomy–work engagement relationship is not always particularly strong. Whereas previous longitudinal studies have examined this relationship as an average at a specific point in time, this study examined whether this relationship is different within individuals from one time to another over the years. Furthermore, experiences of work engagement are expected to affect how employees benefit from autonomy, but no studies have so far investigated whether the initial level of work engagement affects the autonomy–work engagement relationship. This study aimed to first ident…

Development of School and Sport Burnout in Adolescent Student-Athletes: A Longitudinal Mixed-Methods Study.

2018

We investigated the development of school and sport burnout in adolescent student-athletes (N Time 1 = 391, N Time 2 = 373) during their first year in upper secondary school using an embedded mixed-methods design. The questionnaire-based data were analyzed with growth mixture modeling and four burnout profiles were identified among student-athletes. From the found burnout profiles, two were typical for the interviewed subsample of elite athletes (n = 17), that is, burnout risk and non risk profiles. We generated rich descriptions of well-being and ill-being, showing that elite athletes in two burnout profiles differed in their experienced demands and resources related to individual and envi…

Development of need for recovery from work over one year: A person-centered approach

2011

This longitudinal questionnaire study conducted among 274 Finnish employees (57% women, average age 45.9 years) in a variety of jobs aimed at identifying groups of employees who share similar mean levels and changes in need for recovery and finding out whether factors regarded as antecedents of need for recovery distinguish between the different groups of need for recovery across one year. Using mixture modeling eight groups of need for recovery were identified. The individuals identified as closely resembling each other with respect to need for recovery and its change across one year were considered to belong to the same need for recovery group. Five of these groups indicated stable (low, …

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%).…

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…

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…
