Objective: Informational social support can have both positive and negative effects on employees. This research aims to examine the curvilinear relationship between informational social support and employees' cognitive processes, specifically cognitive depletion and creativity. Additionally, we investigate the moderating role of emotional stability on this curvilinear relationship, particularly regarding cognitive depletion.

Methods: A total of 108 male employees in South Korea participated in the study, completing 864 two-wave, time-lagged daily diary questionnaires. The surveys measured informational social support, cognitive depletion, creativity, and emotional stability.

Results: The findings reveal that informational social support enhances employees' cognitive processes up to a certain threshold, after which its effects become detrimental, demonstrating a curvilinear pattern. Furthermore, emotional stability moderates this relationship: emotionally stable employees show a linear relationship between informational social support and cognitive depletion, while emotionally unstable employees exhibit a curvilinear relationship.

Conclusion: Our results suggest that excessive informational social support may harm employees' cognitive processes, indicating that there is an optimal level of support, beyond which the effects become counterproductive.

This field study set out to test whether consumers' history of making decisions in a particular choice context moderated the effectiveness of a nudge intervention to reduce meat consumption. In a Danish hospital canteen that served both staff members and visitors, a combination of nudges (Chef's recommendation sticker + prominent positioning) was implemented to promote vegetarian sandwiches. The sales of these sandwiches increased from 16.45% during the baseline period to 25.16% during the nudge intervention period. Most notably, this increase was caused by the visitors, who had weak location-bound preferences. Hospital staff members (who had strong location-bound preferences) were unaffected by the nudge in their choice. This is an important finding because the two consumer groups did not differ on their person-bound preferences for meat. It seems that behaviour change is best predicted by location-bound preferences, whereas the behaviour itself is best predicted by person-bound preferences. These findings can help organizations in estimating whether a nudge intervention has enough potential for behaviour change, or whether more directive policies are required.

Background: Family carers of people living with comorbid dementia and cancer (CDC) play a vital supportive role, but this may be particularly burdensome and adversely impact their own health and wellbeing.

Objective: To examine the experiences and psychosocial support needs of caregivers of people with CDC.

Methods: A flyer advertising the study was distributed to relevant UK voluntary sector organisations and shared across social media. 13 carers of people with CDC were recruited. In-depth semi-structured interviews were conducted and transcripts were analysed using reflexive thematic analysis, underpinned by an inductive phenomenological approach.

Results: Complex interactions of dementia and cancer resulted in heightened responsibility for carers, who played a crucial role in recognition/management of symptoms, performing difficult cancer-related care, and treatment decision-making that posed difficult ethical challenges. Care-recipients had reduced insight into their cancer diagnosis and prognosis, so carers often carried the emotional burden alone. Responsibilities faced by carers were compounded by a lack of targeted, accessible information/support for CDC. Carers expressed a desire to talk to and learn from others who understand the unique challenges of navigating cancer-related decision-making, treatment and care for people who are also living with dementia.

Conclusions: Cancer alongside dementia presents complex challenges for carers, who desire more cancer-related information and support which is tailored to people living with dementia and their family caregivers.

There is a growing body of research on improving health behaviours through future thinking but that in improving eating behaviour remains unclear. Hence, we conducted a systematic review and meta-analysis on the effectiveness of time perspective manipulation in improving adult eating behaviours. Articles published from inception through 17 March 2022 were retrieved from eight databases (CINAHL, Embase, ProQuest, PsycINFO, PubMed, Scopus, The Cochrane library, and Web of Science). Meta-analysis was conducted using random effects models with effect sizes reported in Hedges' g. Sixteen experimental studies were included, representing 1,914 participants with mean ages ranging from 20.5 to 44.1 years old and mean baseline BMI of 22.0 kg/m² to 37.2 kg/m². The interventions included were episodic future thinking (EFT; n = 12), message framing (n = 2), and varying inter-meal intervals (IMI; n = 2) in improving food choices, food intake and portion size. Two studies reported significant interventional effectiveness for domain-specific EFT while all studies on message framing and IMI reported significant interventional effectiveness. Message framing seemed to be more effective when both temporal distance and valence frames were manipulated. However, the pooled effect sizes of all the interventions did not result in a significant interventional effect (n = 5; g = -0.49; 95% confidence interval (CI) = -1.44, 0.47; p = 0.23; I²=87.2%). More rigorous research is needed to ascertain the effectiveness of manipulating time perspective in improving eating behaviours before such interventions are more widely used.

Objective.

Job strain has been implicated in a variety of adverse health outcomes, particularly cardiometabolic and inflammatory diseases. However, the mechanisms underlying these effects remain largely unknown. One possibility is that the maladaptive coping response to stress, (perseverative cognition (PC); the cognitive representation of past stressful events (rumination) or feared future events (worry)), either in work or more generally, mediates the relationship between job strain and physical disease. The aim of this study was thus to test the potential role of both general, and work- related PC as a mediating, or potentially moderating, mechanism between job strain and ill- health outcomes.

Design & Measures.

Using an online cross- sectional design, 650 full- time employees completed measures of job strain, general and work- related PC (rumination & worry) and health outcomes (burnout, somatization, health behaviours & sleep quality).

Results.

General and work- related worry and rumination significantly mediated, often independently, the relationship between job strain and burnout, somatization, and sleep quality. No significant mediation effects were observed for health behaviours and no type of PC (general or work- related) moderated job strain- health outcome relations.

Conclusion.

Both general and work- related worry and rumination are likely to play important, and partly independent, roles in understanding the adverse relationships between job strain and various health outcomes.

Purpose: Research investigating depressive symptoms among cancer patients rarely distinguish between core symptoms of depression (motivational and consummatory anhedonia, and negative affect). This distinction is important as these symptoms may show different trajectories during the course of the illness and require different treatment approaches. The aim of the present study is to investigate fluctuations in core depressive symptoms in patients with colorectal cancer (CRC). It is hypothesized that these core depressive symptoms fluctuate differently during the course of the illness and depend on the phase of the illness (diagnostic, treatment, recovery and palliative phase).

Method: This study is based on data from the PROCORE study. PROCORE is a prospective, population-based study aimed to examine the longitudinal impact of CRC and its treatment on patient-reported outcomes. Eligible patients completed self-report questionnaires (i.e. Multifactorial Fatigue Index, Hospital Anxiety and Depression scale, EORTC-C30) after diagnosis, after surgery and at one and two years after diagnosis.

Results: In total, 539 patients participated of whom 68 have died until March 1ste 2021. Core depressive symptoms fluctuated differently during the course of the illness with higher levels of motivational anhedonia during treatment and palliative phase (P<.001), consummatory anhedonia at the palliative phase (p < .001) and negative affect at the diagnostic and palliative phase (P<.001).

Conclusion: It is important to distinguish between different core depressive symptoms as they fluctuate differently during the course of an illness like CRC. The various depressive symptoms may require a different treatment approach at specific moments during the illness process.

Objective: The aims of this study were to investigate trajectories of anxiety and depression symptoms among gynaecological cancer (GC) patients having curative-intent radiotherapy (RT) treatment and identify which patient characteristics predict anxiety and depression trajectories.

Methods and measures: Latent profile analysis (LPA) was used to identify unique trajectories of anxiety and depression symptoms, spanning prior to the start of RT until 12-month post-RT, among 151 GC patients in the PeNTAGOn randomized control trial. Demographic and clinical characteristics were assessed at baseline, and anxiety and depression symptoms were assessed five times over 12 months. A bias-adjusted 3-step maximum likelihood approach was used to identify demographic and clinical predictors of trajectory profiles.

Results: Four latent profiles each were identified for anxiety and depression trajectories. Most patients had minimal to mild levels of anxiety or depression that remained steady or declined over 12 months following treatment. A minority of patients were in profiles that exhibited clinically significant distress; either 'High fluctuating' anxiety or 'Mild-moderate fluctuating' depression. Anxiety and depression profiles were predicted by clinical and demographic factors, such as age, living arrangements, RT type, cancer stage, physical symptom distress and use of support services.

Conclusions: Psychological care of patients in the higher distress trajectories is paramount and, importantly, they could be identified prior to treatment based on the factors identified. Review for at least a month post-RT is warranted.

Objective: High quality obstetric anaesthetic care is integral to reducing preventable maternal deaths in Low-and-Middle-Income-Countries (LMICs). We applied behavioural science to evaluate SAFE Obstetrics, a 3-day Continuing Professional Development (CPD) course, on physician and non-physician anaesthetists' practice behaviours across 3 LMICs.Methods: Seven anaesthetist Fellows from Bangladesh, Nepal and Tanzania were trained in qualitative methods and behavioural science. Structured interviews were undertaken by Fellows and two UK behavioural scientists with course participants. Interviews were based on the Theoretical Domains Framework: a comprehensive framework of influences on behaviour change. Interviews were recorded, transcribed and analysed using content and thematic analysis.Results: 78 physician and non-physician anaesthetists participated (n = 26 Bangladesh, n = 24 Nepal and n = 28 Tanzania). Participants reported positive improvements in patient-centered working, safety, teamwork and confidence. Across countries, we found similar barriers and facilitators: environmental resources, a strong professional identity and positive social influences were key facilitators of change.Conclusion: This multi-country theory-based evaluation highlighted the impact of SAFE Obstetrics on participants' clinical practice. A supportive work environment was crucial for implementing learning following training; CPD courses in LMICs must furnish participants with skills and equipment to address training implementation challenges. Building local behavioural science capacity can strengthen LMIC health intervention evaluations.

Objective: Physical activity is important for health, yet most young adults are insufficiently active. Physical activity is regulated in part, by habit, typically operationalised as automaticity. Little is known about the characteristics of automaticity, or whether broad bandwidth unidimensional measures of automaticity for physical activity are superior to narrower bandwidth multi- dimensional measures. Design: This secondary analysis (N = 238) investigated the nature of automaticity, and relations between the dimensions of automaticity, global automaticity, and physical activity.Main Outcome Measures: The structure of the Generic Multifaceted Automaticity Scale (GMAS) was examined by confirmatory factor analyses. Structural equation models were estimated to evaluate relations between automaticity (measured on the GMAS and the Self- Report Behavioral Automaticity Index, SRBAI) and device- measured activity.Results: The hypothesised 3- factor structure of the GMAS was rejected, in favour of a 2- factor solution. Lack of intention/control and efficiency were associated with global automaticity, but not physical activity. Global automaticity was associated with moderate to vigorous physical activity and daily steps, but not light physical activity.Conclusion: Multi- dimensional measures of automaticity may not provide a more nuanced understanding of automaticity when predicting overall physical activity.

Objective: While the stigma experienced by non-drinkers is well-documented, little is known about the factors that influence it. This study aims to test a sequential mediation model in which the amount of alcohol consumed by a drinker, predicts their experienced alcohol-related harm, which in turn predicts the concern they have for drinking and their negative attitudes towards non-drinkers.

Methods: A sample of 787 Australian drinkers (M_age = 38.4 years, SD = 11.4) completed online measures of alcohol consumption, alcohol-related harms, concern for drinking and the Cheers Attitudes towards Non-drinker Scale (CANS): a scale that measures the negative attitudes toward non-drinkers via three threats non-drinkers are perceived to pose to drinkers (Threat to Fun, Connection, and Self).

Results: The model was shown to be a good fit and demonstrated a sequential mediation with significant indirect effects from alcohol consumption via experienced alcohol-related harms and concern, to each CANS subscale: Threat to Self (β = 0.402, p < 0.001), Fun (β = 0.096, p = 0.006) and Connection (β = 0.165, p < 0.001).

Conclusion: The findings suggest that the stigma directed at non-drinkers may be enacted as a defence against an unwanted self-reflection from a drinker's concern for their own drinking.
