The role of body mass index,weight change desires and depressive symptoms in the health-related quality of life of children living in urban disadvantage: Testing mediation models

Objectives: This study was undertaken to ascertain whether or not the body mass index (BMI) of urban disadvantaged children indirectly affects their health-related quality of life (HRQoL) through weight change desires and depressive symptoms and whether such mediation is conditional upon age and gender.

Design: A total of 255 children aged 7–12 years (50% male) were recruited from 7 schools in urban disadvantaged districts in Ireland using consecutive sampling. A prospective longitudinal design was employed whereby children completed, at two time points, the Kidscreen-27, the Children’s Depression Inventory, and the Health Related Behaviour Questionnaire, and had their BMI measured. The analyses involved multiple-, half-longitudinal- and moderated-mediation.

Results: Results showed that the depressive symptoms of children wanting to change their weight may have lead, in large part, to poorer HRQoL (specifically psychological well-being when considering longitudinal data) rather than weight status per se. The mediation effect of weight change desires occurred regardless of age or gender.

Conclusions: Childhood obesity programmes that traditionally focus on the negatives of obesity and the need to control weight may need to take a more positive approach to health and well-being by, for example promoting intuitive eating, an active lifestyle, body acceptance and good mental health.     

Effect of a behavioral intervention on dimensions of self-regulation and physical activity among overweight and obese adults with type 2 diabetes: a pilot study

The purpose of this pilot study was to determine the preliminary effect of a behavioral intervention on the use of self-regulation strategies and moderate-to-vigorous physical activity (MVPA) in overweight and obese adults with type 2 diabetes. 23 individuals recruited from ResearchMatc.org and campus advertisements were randomized into an intervention (n = 12) and control (n = 11) group. The intervention group received a behavioral intervention that used goal setting, time management, and self-monitoring to target dimensions of self-regulation and MVPA. The control received information regarding their PA habits. MVPA was measured via BodyMedia Armbands at pre- and post-test. The use of self-regulatory strategies for MVPA was assessed at pretest and posttest using the Self-Regulation for Exercise Scale. Cohen’s d effect sizes were calculated to determine the practical impact of the intervention. The intervention had a large effect on all dimensions of self-regulation across time: including total self-regulation (3.15), self-monitoring (4.63), goal setting (3.17), social support (1.29), self-reward (1.98), time management (4.41), and overcoming barriers (2.25). The intervention had no impact on dimensions of MVPA across time. This pilot study demonstrated the ability of a behavioral intervention to improve the use of self-regulation strategies for MVPA in a sample of adults with type 2 diabetes. These findings can further inform the development of health promotion programs to promote self-regulation. Future research should focus on determining ability of improvements in self-regulation to stimulate behavior change.     

Do hotter temperatures increase the incidence of self-harm hospitalisations?

A relationship between air temperature and the incidence of suicide has been established in a number of previous studies. Interestingly, the relationship between geographical variation in temperature and suicide incidence has generally been found to be negative, while the relationship between temporal variation in temperature and suicide incidence has generally been found to be positive. It is less clear, however, how temperature relates to the incidence of self-harm. This topic is of particular importance given the presence of ongoing global warming. This study investigated the relationship between temperature and the incidence of self-harm resulting in hospitalisation in New Zealand. Self-harm hospitalisations by date and district for 1993–2009 were obtained from the Ministry of Health. Meteorological data was obtained from NIWA. Generalised linear mixed models were used to estimate the effects of three different components of variation in temperature: geographical, seasonal and irregular. Irregular (random) daily variation in temperature had a modest positive relationship with the incidence of acts of self-harm resulting in hospitalisation, with about 0.7% extra incidents for every 1 °C increase in temperature. However, there was no strong evidence for a positive effect of either seasonal or geographical variation in temperature. We conclude that temperature does appear to bear some relation to the incidence of self-harm, with irregular daily variation in temperature having a positive effect. However, inconsistencies in the effects of different components of variation in temperature make it challenging to accurately predict how global warming will influence the incidence of self-harm.     

Le bilan de compétences : effets sur l’état émotionnel des bénéficiaires

Bilan de compétences (BC)’ effects on workers’ emotional states remain little explored. BC may reduce work-related negative emotional states and enhance positive ones. This was tested using a two-study design. In the first study, 38 respondents filled in the POMS-f, a questionnaire on emotional states, at the beginning or/and at the end of their BC. Six of them were also interviewed one week after the end of their BC. In the second study, 59 respondents filled in the same questionnaire at the beginning and at the end of their BC. In both studies, BC significantly reduced most of negative emotional states and increased positive ones.     

Factorial invariance and latent mean differences of the Beck Depression Inventory – second edition (BDI-II) across gender in South African university students

This study examined the measurement invariance of scores from the BDI-II as well as the differences in latent mean scores by gender. Participants were 919 South African university students (females = 72%). They completed the BDI-II, which is a measure of Negative Attitude (NA), Performance Difficulty (PD), Somatic Complaints (S) and Depression (D). The data were analysed utilising multigroup confirmatory factor analyses (MCFA). Evidence of factorial invariance was established at the level of configural, metric and scalar invariance, across gender groups. Females scored significantly higher latent means on measures of NA and S compared to males.     

Developing a Validity Argument Through Abductive Reasoning with an Empirical Demonstration of the Latent Class Analysis

This article proposes and demonstrates a methodology for test score validation through abductive reasoning. It describes how abductive reasoning can be utilized in support of the claims made about test score validity. This methodology is demonstrated with a real data example of the Canadian English Language Proficiency Index Program (CELPIP)-General test—a program assessing functional English language ability in the community and workplace. Abductive reasoning seeks the enabling conditions through which a claim about a person's ability makes sense. For example, it makes sense that a person has strong functional language proficiency if he or she has been regularly using English to write emails and meet with colleagues at work. A valid test score should be affected by the extent of a person's engagement with such enabling conditions. Empirical evidence that warrants such an abductively reasoned claim is illustrated through a latent class analysis within a structural equation model. Evidence is examined to investigate whether certain classes of test takers who have been differentially engaging in the enabling conditions do, in fact, predict a person's CELPIP-General performance. The steps of the methodology are summarized in the closing section.     

Consequences of voluntary job changes in Germany: A multilevel analysis for 1985–2013

Analyzing the development of the consequences of voluntary job changes in Germany between 1985 and 2013, the study focuses on income gains and job satisfaction increases. Drawing on arguments of the job-search literature on the one hand and the proliferation of choices on the other we investigate whether the returns of job changes have increased or decreased. Results show that income gains have decreased over time while the job satisfaction surplus has remained stable. We further conclude that in determining the outcomes of job changes over time, structural factors seem to be more important than individual ones.     

Changes in disengagement coping mediate changes in affect following mindfulness‐based cognitive therapy in a non‐clinical sample

Past research has shown that mindfulness‐based interventions increase positive affect in non‐clinical populations. However, the mechanisms underlying this increase are poorly understood. On the basis of previous empirical and theoretical accounts, we hypothesized that a decreased use of disengagement coping strategies in daily life would explain the benefits of a mindfulness‐based intervention in terms of increased positive affect. We analysed the data of 75 healthy adult participants (58 women; 17 men) of different ages (M = 49 years old; SD = 13; age range 19–81) who had been randomly allocated to 8‐week Mindfulness‐Based Cognitive Therapy (MBCT) or to a waitlist control group. The results confirmed our hypothesis: Participants in the MBCT group showed significant improvements in positive affect compared to the control group, with decreased use of disengagement coping styles mediating these improvements. The implications of this study are discussed.
