Sunburn is associated with an increased risk for skin cancer. Denmark has one of the highest incidences of melanoma in the world, although it is a relatively northern country. The objective of this study was to determine whether sunburn is associated with demographic factors and health behaviour among young Danes. Cross-sectional data of >55,000 15- to 25-year-old students participating in the Danish National Youth Study were collected in 2014. Multilevel logistic regression analysis was used to determine associations...

INTRODUCTION: Supervised community treatment (SCT) for people with serious mental disorders has become accepted practice in many countries around the world. In England, SCT was adopted in 2008 in the form of community treatment orders (CTOs). CTOs have been used more than expected, with significant variations between people and places. There is conflicting evidence about the effectiveness of SCT; studies based on randomised controlled trials (RCTs) have suggested few positive impacts, while those employing observational designs have been more favourable...

OBJECTIVES: Internet gambling is often considered as a risk factor for gambling problems compared with land-based gambling. In parallel, this online activity generates data that can be useful to characterize Internet gambling behaviours. The objectives were to define a typology of online lotteries and scratch games gamblers' behaviours in order to identify early risky gambling behaviours and to classify gamblers in order to identify individuals with global risky gambling behaviours. METHODS: We performed a multilevel latent class cluster based on player account-based data of 10,000 gamblers from a French online operator...

To promote physical activity (PA) among children, few studies have reported long-term effects of playground marking during school recess. The aim of this study was to investigate the impact of a playground design on children's recess PA across 12 months and to evaluate the influence of covariates on the intervention effects with accelerometry data. Two hundred and eighty-three children (aged 6-11 years) were selected from 3 elementary schools. Two experimental schools received a recess-based intervention; the third one served as a control group...

This article meta-analytically reviews the research on the association between therapist positive regard (PR) and treatment outcome. The history of the construct of unconditional PR in client-centered theory and the efforts to clearly operationalize and measure this construct are reviewed. Several clinical examples are presented. The updated meta-analysis, which features expanded inclusion criteria and a larger number of studies (k = 64) than previous analyses, yielded a small positive association between PR and treatment outcome, g = ...

The timing of events (e.g., how long it takes a child to exhibit a particular behavior) is often of interest in developmental science. Multilevel survival analysis (MSA) is useful for examining behavioral timing in observational studies (i.e., video recordings) of children's behavior. We illustrate how MSA can be used to answer 2 types of research questions. Specifically, using data from a study of 117 children 36 months old (SD = .38) during a frustration task, we examined the timing of their recurring anger expressions, and how this is related to (a) negative affectivity, a dimension of temperament related to the ability to regulate emotions, and (b) children's strategy use (distraction, bids to their mother)...

A great range of person perception phenomena may be conceptualized in terms of how much perceivers know about the targets, how much they like the targets, and how these factors relate to the extent to which target descriptions reflect actual target characteristics and/or evaluative bias. We present a comprehensive empirical analysis of this interplay in two studies, the second (targets: N = 189, informants: N = 1352) being a preregistered replication of the first (targets: N = 73, informants: N = 549). Using multilevel profile analyses, we investigated how liking and knowing are differentially associated with judgments' normative accuracy (i...

The objective of this work was to develop a multilevel (hierarchical) model based on isocratic reversed phase high-performance chromatographic data, collected in methanol and acetonitrile for 58 chemical compounds. Such multilevel model is a regression model of the analyte-specific chromatographic measurements, in which all the regression parameters are given a probability model. It is a fundamentally different approach from the most common approach where parameters are separately estimated for each analyte (without sharing information across analytes and different organic modifiers)...

Both living with children and alcohol consumption are positively associated with intimate partner violence (IPV). We assessed their combined relationship with physical IPV (P-IPV) victimization and perpetration, and explored possible moderating roles of sex and culture. Data included 15 surveys of 13,716 men and 17,832 women in 14 countries from the GENACIS (Gender, Alcohol, and Culture: An International Study) collaboration. P-IPV was measured as victim of physical aggression by an intimate partner (Vic-Only), perpetrator of physical aggression toward a partner (Perp-Only), or both victim and perpetrator (i...

BACKGROUND: Within public health research, generalised trust has been considered an independent predictor of morbidity and mortality for over two decades. However, there are no population-based studies that have scrutinised both contextual-level and individual-level effects of generalised trust on all-cause mortality. We, therefore, aim to investigate such associations by using pooled nationally representative US General Social Survey (GSS) data linked to the National Death Register (NDI)...

Liver injury remains a significant global health problem and has a variety of causes, including oxidative stress (OS), inflammation, and apoptosis of liver cells. There is currently no curative therapy for this disorder. Sanwei Ganjiang Prescription (SWGJP), derived from traditional Chinese medicine (TCM), has shown its effectiveness in long-term liver damage therapy, although the underlying molecular mechanisms are still not fully understood. To explore the underlining mechanisms of action for SWGJP in liver injury from a holistic view, in the present study, a systems pharmacology approach was developed, which involved drug target identification and multilevel data integration analysis...

Background and Objectives: The general view is that partner-caregiver burden increases over time but findings are inconsistent. Moreover, the pathways underlying caregiver burden may differ between men and women. This study examines to what degree and why partner-caregiver burden changes over time. It adopts Pearlin's Caregiver Stress Process Model, as it is expected that higher primary and secondary stressors will increase burden and larger amounts of resources will lower burden. Yet, the impact of stressors and resources may change over time...

BACKGROUND: The obesity epidemic presents a major public health challenge, and a poor diet quality has been identified as one of the most important contributing factors. Whereas a sufficient fruit and vegetable consumption has been associated with several positive health outcomes, the long-term effect on overweight and obesity is unclear. Thus, the aims of this study were to investigate if one year with free school fruit had any effect on weight status 14 years later, and if it affected the birth weight of the participants' children...
