Profiling a Spectrum of Mental Job Demands and their Linkages to Employee Outcomes.

Working life is becoming more mentally demanding and intense due to technological acceleration. The present study explored employees' experiences of different mental job demands (MJDs) and their outcomes (job burnout, job performance, and meaning of work). We focused on intra- and inter-individual variations and possible harmful combinations of MJDs, which we explored via latent profile analysis (LPA).

Do Aging Employees Benefit from Self-Regulative Strategies? A Follow-Up Study.

SOC-strategies (selection, optimization, and compensation) are crucial for well-being and adaptation throughout the life course. The workforce is aging rapidly, thus the age-conditional premises of SOC theory require attention. This study explored (1) whether older employees used SOC strategies more often (compared to younger employees), and (2) whether older employees benefited more from SOC strategies in relation to occupational well-being (job burnout, work engagement).

Intensified job demands and job performance: does SOC strategy use make a difference?

We examined intensified job demands (IJDs) and selecting-optimizing-compensating (SOC) strategies as predictors of job performance (task performance, organizational citizenship behavior). We also investigated SOC strategy use as a moderator in the linkages between IJDs and performance. We sampled three disparate occupational groups (N=4,582).

Nicotine matters in predicting subsequent smoking after e-cigarette experimentation: A longitudinal study among Finnish adolescents.

Background: Several studies indicate an association between e-cigarette use and subsequent smoking among youth. However, most previous studies lack measures of the nicotine content of e-liquid and have not usually measured regular smoking.

Methods: We tested the association between e-cigarette use, with and without nicotine, and subsequent daily use of conventional cigarettes and nicotine e-cigarettes among study population of 3474 students.

Low schoolwork engagement and schoolwork difficulties predict smoking in adolescence?

Background: Low academic achievement has been associated with smoking but factors behind this association are poorly known. Such factors could include schoolwork disengagement and schoolwork difficulties. To assess the extent to which they contribute to the explanation of how health inequalities emerge, we study in a longitudinal design whether these have an independent effect on smoking or whether their effect is mediated through academic achievement.

Psychosocial Problems, Indoor Air-Related Symptoms, and Perceived Indoor Air Quality among Students in Schools without Indoor Air Problems: A Longitudinal Study.

The effect of students' psychosocial problems on their reporting of indoor air quality (subjective IAQ) and indoor air-related (IA-related) symptoms has not been studied in schools in a longitudinal setting. Therefore, we analyzed whether changes in students' psychosocial problems (socioemotional difficulties and perceived teacher⁻student relations) between the beginning of seventh grade (age 12⁻13 years) and the end of ninth grade (15⁻16 years) predicted subjective IAQ and IA-related symptoms at the end of ninth grade. In order to explore the independent effect of psychosocial factors, we focused only on students in schools without observed indoor air problems.

A Longitudinal Study of Predictors for Adolescent Electronic Cigarette Experimentation and Comparison with Conventional Smoking.

Little is known of the predictors of electronic cigarette (e-cigarette) use among adolescents, even though the use is increasing. We studied here the predictors for e-cigarette experimentation (tried and tried more than twice) and compared them with predictors for conventional smoking. A baseline school survey was conducted in the Helsinki metropolitan area, Finland, in 2011 for seventh graders (12 to 13-year-olds).

Health as a Predictor of Students' Academic Achievement: A 3-Level Longitudinal Study of Finnish Adolescents.

Background: Studies have shown a relationship between students' health and their academic achievements, but whether health of classmates and schoolmates impacts individual students' school achievement is less known. We studied these effects on students in lower secondary school in Finland.

Methods: Students (seventh grade, age 12-13 years, N = 7779, 123 schools, 565 classes) participated in a classroom survey measuring health (externalizing and internalizing problems, daily health complaints, and long-term illness) and academic achievement.
