When Deep Learning Outperforms Conventional Models in Long-Term Forecasting
Forecasting long-term health trajectories from intensive longitudinal data (ILD) is essential for timely interventions. Growth Curve Models (GCMs) provide a conventional multilevel framework that o
A qualitative evaluation of a novel mHealth physical activity intervention with just-in-time prompts in people living with prediabetes and type 2 diabetes
Background Physical inactivity and prolonged sitting are major risk factors for prediabetes and type 2 diabetes (T2DM). Despite this, individuals with prediabetes and T2DM often face challenges in maintaining adequate physical activity. The ENERGISED trial aimed to address this by using a mobile health (mHealth) intervention combining wearable Fitbit devices, just-in-time context-sensitive text messages (JITAI), and telephone counselling, tailore…
Examining the Reciprocal Relationship Between Social Media Use and Perceived Social Support Among Adolescents
Adolescents commonly use smartphone social media apps, which can affect their perceived social support (PSS). However, study results on social media’s effect on PSS differ, because they employ a self-reported time in social media use and concentrate only on between-person differences. They often neglect the social-anxiety level, which might be important. Our study investigated whether the within-person day-to-day changes in the time spent in two …
A Three-Generation Perspective on Physical Activity and Sedentary Behavior of School-Aged Children
This scoping review assesses the different roles parents and grandparents play in supporting children’s physical activity and how their roles may interact to create a family climate conducive to physical activity. Systematic searches were conducted in the Web of Science, Scopus, PubMed, and EBSCO databases, following the PRISMA reporting standards. Selected studies (N = 11) examined the intergenerational influences on children’s physical activity…
The temporal dynamics of the association between daily physical activity and life satisfaction
PURPOSE: Life satisfaction (LS) is increasingly recognized as a crucial indicator and predictor of health and well-being across the lifespan. The impact of LS may be enhanced through physical activity (PA), although studies exploring the dynamic and bidirectional nature of the relationship are scarce. One principal goal of this project is to examine the dynamic, personalized interactions between LS and PA and exercise identity (the degree to whic…
(In)accuracy and convergent validity of daily end-of-day and single-time self-reported estimations of smartphone use among adolescents
Understanding the measurement inaccuracy and bias introduced by self-reports of smartphone use is essential for making meaningful inferences about smartphone use and its effects. Evidence for the self-reports of smartphone use in intensive longitudinal studies is largely missing. Based on self-reported and digital trace data from 137 Czech adolescents (41% girls, Mage = 14.95 years), this study examined the accuracy, directional bias, and converg…
Participatory development of an mHealth intervention delivered in general practice to increase physical activity and reduce sedentary behaviour of patients with prediabetes and type 2 diabetes (Energi…
The participatory development of the ENERGISED mHealth intervention, incorporating just-in-time prompts, has the potential to significantly enhance the capacity of general practitioners for personalised behavioural counselling on physical activity in (pre)diabetes patients, with implications for broader applications in primary care
Are smartphones detrimental to adolescent sleep? An electronic diary study of evening smartphone use and sleep
Previous research associated smartphone use with worsened sleep among adolescents. However, the prior findings were mainly based on cross-sectional, self-reported data, and a between-person level of analysis. This study examined between- and within-person associations for adolescents' smartphone use and multiple sleep outcomes: sleep onset time, sleep onset latency, sleep duration, subjective sleep quality, and subjective daily sleepiness. The pa…

Physical activity in an air-polluted environment
The design of the study will allow for (1) the assessment of both short-term variation and long-term change in behavioral parameters, (2) evaluation of the incidence of musculoskeletal injuries and psychological factors impacting behavior and injury recovery, and (3) the impact that air pollution status (and change) has on behavior, psychological resilience, and injury recovery. Furthermore, the integration of MRI techniques and cognitive assessm…
Does living together or apart matter? A longitudinal analysis of relationship formation in later life in association with health, well-being, and life satisfaction
Despite a growing body of research on later-life relationship formation, little is known about the health predictors and outcomes of later-life Living-Apart-Together (LAT) relationships. A LAT living arrangement is understood to be a possible way for older adults with age-related limits to partner and balance the consequences of being single. Using both selection and resource models to capture the links between health and relationship status, we …
Running and Physical Activity in an Air-Polluted Environment
Far too little attention has been paid to health effects of air pollution and physical (in)activity on musculoskeletal health. The purpose of the Healthy aging in industrial environment study (4HAIE) is to investigate the potential impact of physical activity in highly polluted air on musculoskeletal health. A total of 1500 active runners and inactive controls aged 18-65 will be recruited. The sample will be recruited using quota sampling based o…
Weekly Fluctuations in College Student Leisure Activities and Well-Being
College students’ well-being is declining. Differences in students’ leisure activity participation have been linked to their psychological well-being. This study examined how weekly fluctuations in leisure allocation (i.e., frequency of volunteer, cognitive, social, club, religious, and physical activities) related to well-being in college students. Students completed weekly leisure time allocation assessments. Generalized linear multilevel analy…
Validation of Geriatric Depression Scale–5 Scores Among Sedentary Older Adults
This study examined the validity of Geriatric Depression Scale–5 (GDS-5) scores among older sedentary adults based on its structural properties and relationship with external criteria. Participants from two samples ( Ns = 185 and 93; M ages = 66 and 67 years) completed baseline assessments as part of randomized controlled exercise trials. Confirmatory factor analysis supported a single-factor model for the GDS-5, the GDS-5 exhibited adequate sens…
Physical activity enhances long-term quality of life in older adults
BACKGROUND: Physical activity has been effective in enhancing quality of life (QOL) of older adults over relatively short periods of time. However, little is known about the long-term effects of physical activity and even less about the possible mediators of this relationship. PURPOSE: We examined the mediating effects of psychological variables on the relationship between physical activity and global QOL (satisfaction with life) in older adults …
Physical Activity, Self-Efficacy, and Self-Esteem
We examined the structure of the expanded version of the Exercise and Self-Esteem Model in a sample of older adults (N = 174; age, M = 66.7 years) across a 4-year period. A panel analysis revealed support for the indirect effects of physical activity (PA) and self-efficacy (SE) on physical self-worth and global esteem through subdomain levels of esteem. These relationships were consistent across the 4-year period. Over time, older adults reportin…
