The distressed (Type D) personality mediates the relationship between remembered parenting and psychological distress in cardiac patients

Objective: Both the distressed (Type D) personality (i.e. the combination of negative affectivity and social inhibition traits) and dysfunctional parenting styles are associated with anxiety and depression. As parenting styles have been related to personality development, dysfunctional parenting styles may also be associated with Type D personality. We examined whether remembered parenting was associated with anxiety and depression in cardiac patients and whether Type D personality mediated this relationship.

Methods: Our sample comprised 435 patients treated with percutaneous coronary intervention (PCI) and 123 patients with congestive heart failure (CHF). Patients completed the Hospital Anxiety and Depression Scale, Type D Scale (DS14), and Remembered Relationship with Parents (RRP¹⁰) scale.

Results: Remembered parenting was significantly associated with higher anxiety and depression levels and Type D personality. In multivariable linear regression analyses, Type D personality accounted for 25–29% of the variance in anxiety and 23–46% of the variance in depression, while remembered parenting was no longer significantly associated with these domains. Sobel tests and bootstrapping indicated that Type D personality mediated the relationship between remembered parenting and anxiety and depression.

Conclusion: Type D personality mediated the relationship between remembered parenting and anxiety and depression in both PCI and CHF patients.     

Adolescents’ movement towards cessation of smoking: Role and relative value of the processes of change and nicotine dependence

The present study addresses the applicability of the Transtheoretical Model's processes of change in explaining adolescents’ readiness to quit smoking. Furthermore, the association between nicotine dependence and readiness to quit was assessed both directly, as well as indirectly through the processes of change. A cross-sectional survey was conducted, identifying 1547 weekly smokers aged 14–18 years. Structural equation modelling showed that the processes of change were only marginally associated with readiness to quit. Adding nicotine dependence to the model showed a direct association between nicotine dependence and readiness to quit. Only one process of change, self-liberation (i.e. choice/commitment to change and belief in the ability to change), was found to mediate this association. Nicotine dependence appeared to be highly important in adolescents’ readiness to quit.     

Depressive mood and smoking onset: A comparison of adolescents with and without asthma

This prospective population-based study aimed to compare associations between depressive feelings and smoking behaviour of adolescents with and without asthma. Data were collected from a two-wave 22–24 months prospective study among 5938 adolescents who completed self-report questionnaires. Logistic regression analyses showed that depressive feelings and smoking were related both cross-sectionally and longitudinally. Smoking behaviour was similar for adolescents with and without asthma, as well as its correlation with depressive feelings. However, participants with asthma were more likely to report depressive feelings than those without asthma, implying an indirect relationship between asthma and smoking behaviour. Implications for prevention are addressed.     

How highlighted utensils influence consumption in a dark setting

Abstract

Objective: Previous research has shown that people consume less food in the dark compared to normal vision conditions. While this effect is commonly attributed to increased attention to internal cues, it could also be caused by increased difficulty to maneuver in a dark setting. This study investigated this potential alternative explanation.

Design: A 2 (dark versus normal vision setting)?×?2 (highlighted versus non-highlighted utensils) between-subjects design was employed.

Main outcome measures: Perceived difficulty of maneuvering and consumption of yoghurt were assessed as main outcome measures.

Results: Participants consumed marginally less in dark compared to normal vision conditions, and experienced higher difficulty of maneuvering. Importantly, both effects were qualified by a significant interaction with highlighting, which increased consumption and reduced perceived difficulty compared to no highlights. Difficulty of maneuvering did not mediate the interactive effect of vision and highlighting on consumption.

Conclusion: Difficulty to maneuver should be considered when investigating eating behaviour under dark conditions. In line with an embodied cognition account, results also reveal the necessity of visual information for interaction with objects in the environment and imply that detail-deprived object information may be sufficient for activation of the motor system.     

Relationship between the number of life events and memory capacity in children

Stressful life events can result into declined memory performance at later age. One hypothesis suggests that stress affects the hippocampus, a brain area important for memory functioning. This study explored a potential relationship between the number of negative stressful life events and hippocampus-dependent declarative but not hippocampus-independent procedural memory performance in a community sample of 255 children, aged 6–12 years. The findings revealed that negative stressful life events were negatively related to verbal declarative memory, but not to nonverbal declarative and procedural memory. The memory impairments could not be accounted for by attention and sleep disturbances, and parenting characteristics as perceived by the child did not influence the vulnerability for the stress-related memory impairments. These findings provide further insight into the deleterious effects of negative stressful life events on learning in school-aged children.     

Compositions of different phases appearing during devitrification of Zr46.75Ti8.25Cu7.5Ni10Be27.5 bulk metallic glass

The devitrification process of Zr_46.75Ti_8.25Cu_7.5Ni₁₀Be_27.5 metallic glass during annealing in the supercooled liquid region has been studied by conventional, high-resolution and analytical transmission electron microscopy (TEM). Two kinds of particle appear during devitrification: quasicrystals and crystalline precipitates. Nanoanalysis with energy-dispersive X-ray spectroscopy and electron energy-loss spectroscopy reveal that quasicrystals are Be free, while the crystallites have the ZrBe₂ hexagonal structure. These experiments confirm the key role of Be during devitrification. They also indicate that quasicrystals can form in the system Zr–Ti–Cu–Ni (without Be), as further evidenced by direct synthesis and an in situ neutron diffraction investigation, according to the chemical composition deduced from the TEM analysis.     

An anxiety-induced bias in the perception of a bistable point-light walker

Human sensitivity for social cues is exquisite, as illustrated by the ease with which simplified point-light movements invoke social and emotional responses. Compared to faces, these biological motion stimuli only recently started to be used to explore questions regarding social cognition and anxiety. We presented human point-light walkers that could be perceived as facing towards or facing away from the observer, and tested whether participants with high social anxiety would perceive these bistable stimuli differently, because this type of stimuli has particular relevance for them. The results showed that observers with high social anxiety tended to see walkers as facing away more frequently than those with low social anxiety. This may mean that high socially anxious observers are biased towards the more positive perceptual alternative because they are motivated to protect themselves against threatening social experiences, but we also explore alternative explanations. The findings are in line with the evidence for a positivity bias in perception, also called wishful seeing, but in contrast with the attentional negativity bias often found in social anxiety. We discuss reasons for this divergence and possible limitations of the current study.     

The psychosocial well-being of a “forgotten” South African community: the case of Ndumo,KwaZulu-Natal

This study investigated the psychosocial well-being of an indigenous cultural community in South Africa, using a sequential explanatory mixed-methods design. Data on life satisfaction and emotional, social and psychological well-being were collected from 521 local residents (48% female) of Ndumo in KwaZulu-Natal, South Africa using the Satisfaction-with-Life Scale and Mental Health Continuum. In addition, interviews were conducted with 20 Ndumo residents (35% female). Findings revealed that community members had above-average levels of psychosocial well-being and exhibited significant resilience towards countering socio-economic under-resourcing, including poverty and unemployment. The community resources found to aid resilient living included being able to live off the land, a pleasant climate, personal safety, hope for a better future, and instrumental, material, and social support from philanthropic organisations.     

Psychological strengths and subjective well-being in South African white students

This study investigated the role of individual resources, notably self-efficacy, gratitude, and hope, in subjective well-being of white dormitory students at a historically white institution of higher learning. Using a convenience sample of white students (N?=?227), we tested the role of generalised self-efficacy, gratitude, and hope as indicators of a latent factor, labelled personal resources, in a structural equation model with subjective well-being as the latent output variable, measured by self-esteem and satisfaction with life. Path analyses indicated a reasonable fit between the data and our hypothesised theoretical model which proposed positive relations between levels of generalised self-efficacy, gratitude, dispositional hope, self-esteem and satisfaction with life. White students were psychologically doing well, considering above-midpoint levels obtained for levels of generalised self-efficacy, gratitude, dispositional hope, and satisfaction with life However, scores obtained for self-esteem and adult dispositional hope were below the mid-point and neutral respectively, indicating that White students do not agree that they experience high levels of these two psychological strengths. White female students experienced higher levels of hope, gratitude, and life satisfaction, while no significant gender differences were found for generalised self-efficacy and self-esteem. The results of this study highlight the potential for using psychological strengths to promote well-being in racially diverse students.     

Psychological Empowerment,Work Engagement and Turnover Intention: The Role of Leader Relations and Role Clarity in a Financial Institution

This study investigated the relationship between leader-member exchange, role clarity, psychological empowerment, engagement and turnover intention within a financial institution in South Africa. A cross-sectional survey design was used. A convenience sample (N = 278) was taken (males =31%, females =60%; 88% younger than 35 years; 57% with 2–5 years service) from the total population (N = 889). They completed the Leader-Member Exchange Questionnaire (Liden, Wayne, & Stilwell, 1993) Role Conflict and Ambiguity Questionnaire (Rizzo, House, & Lirtzman, 1970), Measuring Empowerment Questionnaire (Spreitzer, 1995), Engagement Questionnaire (May, Gilson, & Harter, 2004) and Intention-to-leave Scale (Sjöberg & Sverke, 2000). A path model was tested with SPSS to determine the relationships of the variables. Furthermore, a theoretical model was tested through the use of structural equation modelling (Arbuckle, 2008). The latent variables included LMX (consisting of two parcels), role clarity (consisting of two parcels), psychological empowerment (consisting of four variables, namely meaning, competence, impact, and self-determination), work engagement (consisting of two parcels), and turnover intention (a manifest variable). Role clarity mediated the relationship between leader-member exchange and psychological empowerment, while psychological empowerment mediated the relationship between role clarity and work engagement as well as turnover intention. Leader-member relations lead to better understanding of roles, while role clarity empowers and engages employees.
