RESUMO

Mass Casualty Incidents (MCIs) rapidly overwhelm the ability of local medical resources to deliver comprehensive and definitive medical care and they have been occurring more frequently in recent decades and affect countries of all socioeconomic backgrounds (Hart et al., 2018). As such, it is important to understand how individuals make such decisions in these events and what factors can hinder or help the process. In this study we focused on the critical role of maximization within MCI triage. Triaging an MCI requires juggling the demand and supply of resources, time, and focus, likely leading to various decisions involving compromise/sacrifice. In a vignette study, hosted on Amazon Mturk (n = 235, Mean age = 38.05, 51.49% self-identified as male), which involved triaging over 100 patients we found that trait differences maximization impacted the willingness to use a "black tag". Furthermore, maximization also impacted how much information an individual needed about the patient before being willing to use a black tag. Overall, this research demonstrates the importance of understanding factors that create individual differences in how people make decisions during MCI events, especially those decisions that involve the use of potentially lifesaving treatments.

RESUMO

Food insecurity - defined as having limited access to nutritious foods - is linked with obesity. Previous research has also shown that food insecurity is associated with lower levels of leisure-time physical activity (physical activity performed outside of essential activities). This association may occur in part due to concerns about preserving levels of energy during times of food shortage. Currently, no scale exists which measures this construct. Therefore, we aimed to develop and validate such a scale - the food insecurity physical activity concerns scale (FIPACS). Participants (N = 603, individuals with food insecurity = 108) completed an online survey, consisting of the FIPACS, the International Physical Activity Questionnaire short-form (IPAQ), the restraint subscale of the Dutch Eating Behaviour Questionnaire (DEBQ), the amotivation subscale of the Behaviour Regulation In Exercise Questionnaire-2 (BREQ-2), and the Behavioural Inhibition System/Behavioural Approach System Reactivity scale (BIS/BAS) to assess convergent and divergent validity. An exploratory factor analysis revealed a four-factor model of the FIPACS - namely 'Concerns relating to hunger', 'Concerns of replenishment and calories', 'Concerns of physiological effects of exercise' and 'Compensatory behaviours' which was verified through a confirmatory factor analysis. To assess test-retest reliability, 100 participants completed the FIPACS again two weeks later. The FIPACS had good internal, test-retest reliability and divergent validity. However, there was limited evidence of convergent validity. Future studies could incorporate this scale when investigating the association between food insecurity and physical activity.

RESUMO

OBJECTIVE: Mothers of premature infants are more likely to develop anxiety during the first postpartum year than mothers of term infants. However, commonly used measures of anxiety were developed for general adult populations and may produce spurious, over-inflated scores when used in a postpartum context. Although perinatal-specific tools such as the Postpartum Specific Anxiety Scale [PSAS] offer a promising alternative form of measurement, it is not clear whether the measure performs similarly in mothers of premature infants as it does in mothers of term infants. The objective of the current study was to identify whether items on the Postpartum Specific Anxiety Scale - Research Short Form (PSAS-RSF) are being interpreted in the same manner in mothers of term infants and mothers of premature infants. Mothers (N = 320) participated in an international on-line survey between February 2022 and March 2023 (n = 160 mothers of premature infants, n = 160 mothers of term infants) where they completed the PSAS-RSF. Data were analysed using a measurement invariance analysis to assess whether constructs of the PSAS-RSF are performing in a similar manner across the two groups. RESULTS: Whilst the PSAS-RSF achieved configural invariance and so retains its four-factor structure, metric invariance was not reached and so items are being interpreted differently in mothers of premature infants. Items concerning infant-separation, finance, and anxieties surrounding infant health are potentially problematic. Future research must now modify the PSAS-RSF for specific use in mothers of premature infants, to ensure measurement of anxiety in this population is valid.

RESUMO

Introduction: It is well established that a premature birth increases the likelihood of developing anxiety during the postpartum period, and that the environment of the neonatal intensive care unit (NICU) might be a contributing factor. Mothers of earlier premature infants may experience these anxieties to a higher degree compared to mothers of later premature infants. The aim of this study was to explore the association between prematurity and postpartum-specific anxiety, and the relationship between postpartum-specific anxiety and stress in the NICU. Materials and methods: Mothers (N = 237) of infants aged between birth and 12 months completed an online survey containing the Postpartum Specific Anxiety Scale - Research Short Form (PSAS-RSF) and the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS:NICU). Structural equation modeling was used to analyze the relationship between gestational age and postpartum-specific anxiety, with one-way ANOVAs used to analyze this relationship with respect to categories of gestational age. Hierarchical regression models analyzed the relationship between postpartum-specific anxiety and stress in the NICU. Results: For the PSAS-RSF, Practical Infant Care Anxieties (p = 0.001), Maternal Competence and Attachment Anxieties (p = 0.033), and Infant Safety and Welfare Anxieties (p = 0.020) were significantly associated with week of gestation. Practical Infant Care and Infant Safety and Welfare Anxieties were significantly higher for mothers of late premature infants, compared to mothers of term infants (p < 0.001; p = 0.019). There were no significant between-group differences with respect to Maternal Competence and Attachment Anxieties. After controlling for potential confounders, Infant Safety and Welfare Anxieties were significantly associated with increased stress in the NICU (p < 0.001) as measured by the PSS:NICU. Conclusions: Our findings highlight the need for interventions for mothers with premature infants, which specifically target anxieties reflected in the PSAS-RSF, such as routine care and increasing maternal self-efficacy.

RESUMO

Food marketing in television and digital media negatively affects appetitive sensations and eating behaviour in children, but effects are less well understood for outdoor food advertising and adults. This research used Ecological Momentary Assessment (EMA) to explore associations between exposures to food advertising in various contexts (television, digital, outdoors) and adults' hunger and craving for highly advertised food categories. Over one week, participants provided ratings of cravings for types of food (fast food, soft drinks, snacks/confectionery, other) and hunger on a smartphone app up to six times per day when they saw a food advertisement (reactive assessment) and at random intervals (random assessment). Fifty-four participants (70.4 % female; 21.24 ± 3.84 years) provided 1223 assessments (24.7 % reactive, 75.3 % random). Data were analysed in R using multilevel multivariable linear regression models. Participants reported feeling hungrier (X2(1) = 5.85, p = .016, ΔAIC = 3.9) and having stronger cravings (X2(1) = 20.64, p < .001, ΔAIC = 318.6) after seeing food advertisements vs. random assessments. This was driven by greater hunger following television advertising exposure vs. random assessments (ß = 1.58, SE = 0.61, p = .010, 95 %CIs 0.38 to 2.78), food advertising via digital devices or outdoors was not associated with hunger. Participants experienced stronger craving after seeing a food advertisement on television (ß = 0.52, SE = 0.19, p = .006, 95 %CIs 0.15 to 0.89), outdoors (ß = 0.39, SE = 0.12, p < .001, 95 % CIs 0.16 to 0.62) and in digital media (ß = 0.36, SE = 0.14, p = .012, 95 % CIs 0.08 to 0.64), vs. random assessments. Cravings were (largely) specific to the advertised food category. EMA can be effective for assessing food marketing associations in adults. The current study provides evidence that food marketing is associated with hunger and craving in adults, which may, with replication, have implications for public health policy.

RESUMO

Food and non-alcoholic beverage (hereafter: food) marketing is prevalent in digital media and predominantly for foods high in fats, salt and/or sugar (HFSS). However, little is known about food marketing in videogame livestreaming platforms - a hybridisation of social and gaming media where individuals can watch influencers (i.e., streamers) play videogames. No studies have explored food cues within the streamed content or content likely to be viewed by adolescents. The current study analysed the food cues in Twitch (the leading videogame livestreaming platform) videos (n = 52, 52h) uploaded to the platform during October 2020-September 2021 by influencers likely to be popular with adolescents. Food cues (n = 133, 2.56 per hour) were coded for exposure (e.g., display type, healthfulness) and power (e.g., presentation) using a World Health Organization (WHO) protocol and the UK Nutrient Profile Model. The majority (70.7%) of cues were HFSS, with energy drinks being the most featured food category (62.4%). Most cues were branded (80.5%) and featured as either product placement (44.4%) or a looping image (40.6%). Influencers were more likely to consume healthy (88.5%) than HFSS items (33.4%). The mean duration of each food cue was 20 min and 25 s per hour. Only 2.3% of cues had an advertising disclosure. This study provides the first empirical assessment of food cues on Twitch in livestreamed content likely to be popular with adolescents and has implications for digital food marketing policy development.

RESUMO

BACKGROUND: The IBD-Control Questionnaire is a simple, generic measure of patient-perceived disease control used increasingly in clinical practice and research. We aimed to address knowledge gaps in its psychometric performance, to ensure that it can be used with confidence in a variety of contexts. METHODS: We analysed 7341 responses to the IBD Registry COVID-19 survey, sent to 40 911 patients who completed an online self-assessment tool during the pandemic. Questions covered demographics, comorbidities, inflammatory bowel disease [IBD] sub-type, and IBD-Control Questionnaire and symptom scores [CD-PRO2 or UC-PRO2]. Psychometric properties of IBD-Control-8 were tested overall and within subgroups (Crohn's disease [CD], ulcerative colitis [UC] and IBD unclassified; male and female; ≤65 and >65 years; number of co-morbidities; deprivation status). RESULTS: Internal consistency was very strong overall [α: 0.84, ω: 0.89] and for each subgroup [α range: 0.81-0.85; ω: 0.86-0.90]. Construct validity was demonstrated by moderate correlation of each item with global rating [VAS] [rs range: 0.47-0.65], strong correlation between IBD-Control-8 score and VAS [rs = 0.74], moderate-to-strong with PRO2 scores [CD: rs = -0.718; UC: rs = -0.602] and significantly higher IBD-Control-8 scores for PRO2-remission vs PRO2-active, consistent across subgroups. Exploratory and confirmatory factor analyses demonstrated a two-factor model (items loading onto 'Health-related Quality of Life' [HRQoL] or 'Treatment' domains). Extensive tests for factorial invariance confirmed consistency. CONCLUSIONS: IBD-Control-8 is a psychometrically robust scale which can be used across a range of populations. It offers a quick, reliable, and valid method of assessing patient-perceived control. The construct of 'control' includes traditional HRQoL and a novel domain relating to treatment perception.

RESUMO

BACKGROUND/OBJECTIVE: Sugar-sweetened beverages are a substantial source of dietary sugar that can contribute to weight gain and the risk of type 2 diabetes. Dietary guidelines recommend non-nutritive sweetened (NNS) beverages to reduce sugar consumption, however, there is a need for long-term randomised controlled trials on their use. We aimed to compare the effects of NNS beverages and water on body weight during weight loss and maintenance in a behavioural weight management programme. METHODS: In this parallel-group, open-label, controlled equivalence trial, adults with a BMI of 27-35 kg/m2 who regularly consumed cold beverages were randomised 1:1 to water or NNS beverages. Participants underwent a group behavioural weight management programme comprising weekly (during the 12-week weight-loss phase) then monthly (during the 40-week weight-maintenance phase) meetings. The primary endpoint was weight change at week 52 (equivalence: two-sided P > 0.05). Secondary endpoints included changes in anthropometrics, cardiometabolic risk factors, appetite and activity levels. RESULTS: Of 493 participants randomised (water: n = 246; NNS beverages: n = 247), 24.1% were NNS-naïve. At week 52, water and NNS beverages were non-equivalent, with significantly greater weight loss in the NNS beverages group. Participants consuming water maintained a weight loss of 6.1 kg over 52 weeks versus 7.5 kg with NNS beverages (difference [90% CI]: 1.4 kg [-2.6, -0.2]; p < 0.05). CONCLUSIONS: During a 52-week behavioural weight management programme, water and NNS beverages were non-equivalent, with weight loss maintained to a statistically greater extent with NNS beverages compared with water. However, this difference was not clinically significant. CLINICAL TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov: NCT02591134.

RESUMO

OBJECTIVE: Children's exposure to unhealthy food marketing contributes to poor diets by influencing the foods that children like, request, buy and consume. This study aimed to use confirmatory mediational analyses to test a hypothetical model of marketing effects, to better understand the mechanisms behind food marketing's impacts on children. DESIGN: Children responded to a cross-sectional online survey about their attitudes towards, and purchase and consumption behaviours of, ten frequently promoted food/beverage brands and their media use. Structural equation modelling tested a priori potential pathways for the effects of food marketing exposure on children's diets. PARTICIPANTS: 10-16-year-old children (n 400). SETTING: Australia. RESULTS: There was a significant positive correlation between children's commercial screen media use and their attitudes towards brands (related to perceived social norms) and their brand purchasing behaviours, including their own purchases and requests to parents. The use of strategies to avoid advertising in commercial screen media reduced but did not remove the association between media use and brand purchases. Other brand exposures (on clothing, outdoor advertising, sponsorships) had a positive association with children's perceived social norms about brands and their brand purchases and requests. Non-commercial screen media use was not associated with any brand-related outcomes. CONCLUSIONS: Commercial screen media use and other brand exposures were strongly positively associated with children's perceptions and purchasing behaviours of frequently marketed food/beverages. Regulations to restrict children's exposures to food marketing on-screen and through other media are required to reduce the effect of marketing exposure on children's food purchasing behaviours.

RESUMO

Introduction: While often positive, the lifecourse transition to motherhood is susceptible to the risk for developing mood disorders. Postpartum anxiety has often been overshadowed by other perinatal-specific mental health disorders, such as postpartum depression, and therefore has not been at the forefront or center of as much empirical study. This has meant there is a lack of effective and reliable tools with which to measure it, despite growing evidence suggesting its detrimental impact on mothers, their babies, wider family and social contacts, and on healthcare systems. This current study aimed to translate and validate the Postpartum Specific Anxiety Scale [PSAS] into the Italian language, and to validate the tool for its use in detecting anxiety specific to motherhood. Methods: The study (N = 457) comprised 4 stages: English-Italian translation and back-translation to obtain the Italian version [PSAS-IT]; a preliminary pilot study to adapt the PSAS to the characteristics of the Italian population; measurement invariance; and internal reliability of subscales. Results: The PSAS-IT demonstrates similar psychometric properties as the original English-language PSAS, with acceptable acceptability, construct and convergent validity, and internal consistency. Confirmatory factor analysis for multiple groups (Italy and United Kingdom) showed that the factor structure of the PSAS was valid for both groups [χ2 (2436) = 4679.481, p < 0.001, TLI = 0.969, CFI =0.972, RMSEA = 0.045, SRMR =0.064]. Discussion: The resulting findings offer a reliable measure of postpartum anxiety in Italian language up to six months after birth.

RESUMO

Videogame livestreaming platforms are an emerging form of digital media, popular with young people, where users watch gaming influencers play videogames. Food and non-alcoholic beverage (hereafter: food) brands have a substantial presence on these platforms, yet no studies have examined the impact of this food marketing on young people. This systematic review and meta-analysis examined the evidence (quantitative or mixed-method) for a relationship between exposure to digital game-based or influencer food marketing, and food-related (brand awareness, attitudes, preferences, purchase, and consumption), and post-consumption (weight, body mass index [BMI], and dental caries) outcomes in young people (≤18 years). Twenty-three databases were searched in March 2021. Twenty-two studies met the inclusion criteria, of which 20 were included in the quantitative synthesis. Meta-analyses indicated food marketing was associated with more positive attitudes and greater preferences (OR = 1.74, p < 0.001 [95%CI: 1.355, 2.232]), and increased consumption (SMD = 0.37, p < 0.001 [95%CI: 0.219, 0.529]). Narrative synthesis indicated that food marketing may increase brand awareness but not pester intent, although data were limited. Evidence suggests that there is a relationship between exposure to food marketing via influencers and digital gaming media, and several food-related outcomes. This is the first quantitative synthesis to demonstrate these relationships; this work has implications for food marketing policy.

RESUMO

BACKGROUND: Statistics anxiety is common among social science students. Despite much evidence examining statistics anxiety and test performance, little research has explored the role of student self-prediction on test performance in a higher education setting. OBJECTIVE: The purpose of this study was to investigate the relationship between statistics anxiety and both students' self-prediction of their future exam performance and actual test performance on a formal statistics assessment at undergraduate level in psychology students in the UK. METHOD: Using a cross-sectional design, two hundred and two students were required to complete Statistics Anxiety Rating Scales, the Mathematical Prerequisites for Psychometrics Scale, and provided self-predicted test performance scores. Test performance data was obtained from a formal statistics assessment. RESULTS: As predicted, we demonstrated statistics test anxiety to be negatively associated with self-predicted performance. Additionally, we found statistics anxiety was positively associated with test performance. CONCLUSION: The findings highlight the complex relationship between statistics anxiety and test performance, suggesting there may be an optimal level of anxiety for performance in statistics assessments. IMPLICATIONS: The results we report have implications for psychology research methods and statistics instructors who may wish to incorporate the findings into statistics instruction modules in order to assuage high levels of statistics anxiety and foster student well-being.

RESUMO

OBJECTIVE: The aim of this study was to compare non-nutritive sweetened (NNS) beverages versus water for weight loss after a 12-week behavioral weight-management program. METHODS: This is an ongoing, 2-year, parallel-group, open-label, controlled equivalence trial; week-12 data are reported. Adults with BMI of 27 to 35 kg/m2 who regularly drank cold beverages were randomized 1:1 to intention-to-treat water or NNS beverages while undergoing a weekly 12-week group behavioral weight-management program. Weight change to week 12 was the primary end point (equivalence: two-sided p > 0.05); changes in waist and hip circumference, blood pressure, glycemic control markers, fasting lipid profiles, liver function tests, hunger (visual analog scale), sugar and sweetener consumption, and activity levels were secondary end points. RESULTS: Overall, 493 participants were randomized (water: n = 246; NNS beverages: n = 247); 24.1% were NNS beverage naïve. Weight change was equivalent with water versus NNS beverages (-5.6 vs. -5.8 kg; difference [90% CI]: -0.2 kg [-0.7 to 0.4]). There were no significant differences between groups for secondary end points except reductions in waist circumference (greater with NNS beverages vs. water), glycated hemoglobin, and consumption of any type of sweetener (both greater with water vs. NNS beverages). CONCLUSIONS: Weight loss was equivalent with NNS beverages and water following a 12-week behavioral weight-management program.

RESUMO

Dietary temptations and lapses challenge control over eating and act as barriers toward successful weight loss. These are difficult to assess in laboratory settings or with retrospective measures as they occur momentarily and driven by the current environment. A better understanding of how these experiences unfold within real-world dieting attempts could help inform strategies to increase the capacity to cope with the changes in appetitive and affective factors that surround these experiences. We performed a narrative synthesis on the empirical evidence of appetitive and affective outcomes measured using ecological momentary assessment (EMA) during dieting in individuals with obesity and their association with dietary temptations and lapses. A search of three databases (Scopus, Medline, and PsycInfo) identified 10 studies. Within-person changes in appetite and affect accompany temptations and lapses and are observable in the moments precipitating a lapse. Lapsing in response to these may be mediated through the strength of a temptation. Negative abstinence-violation effects occur following a lapse, which negatively impact self-attitudes. Engagement in coping strategies during temptations is effective for preventing lapses. These findings indicate that monitoring changes in sensations during dieting could help identify the crucial moments when coping strategies are most effective for aiding with dietary adherence.

RESUMO

Digital media has become an integral part of adolescents' lives. Mirroring this trend, food and non-alcoholic beverage (hereafter: food) brands increasingly promote products in digital media to maximise reach with young consumers. Videogame livestreaming platforms, where individuals can broadcast or watch streamed videogame footage, are a growing form of digital media. The top three platforms (market share by hours watched) are Twitch (72%), YouTube Gaming (13%), and Facebook Gaming Live (9%), with a combined 34.6 billion hours watched in 2021. These platforms represent a hybridisation of two popular digital trends amongst teenagers: viewing online video content and playing videogames. On these platforms, gaming influencers promote food brands and products, with energy drinks and fast-food restaurants representing the most frequently promoted categories. Evidence suggests that food marketing via Twitch is associated with food craving, purchasing and consumption in adults. Yet, despite the evident teenage appeal and prevalence of food marketing on these platforms, research is yet to explore its associations with adolescent eating behaviour. Adolescents (n = 490, Mage = 16.81, 30.2% female) completed an online cross-sectional questionnaire exploring their recall of food marketing on the top three videogame livestreaming platforms, and relevant behavioural (purchase, consumption) and health (Body Mass Index) outcomes. Structural equation modelling was used to explore hierarchical relationships between the key variables. Results showed that recall of unhealthy food marketing on these platforms was significantly associated with purchase and consumption of marketed food categories. Attitudes towards unhealthy foods mediated this relationship. Findings are the first to demonstrate the relationships between unhealthy food marketing via videogame livestreaming platforms and adolescent eating behaviours, which has implications for the design of policies to restrict digital food marketing to young people.

RESUMO

BACKGROUND: COVID19, and associated lockdown restrictions, have impacted on people's daily lives. Understanding the mental health and wellbeing implications of these impacts has been identified as a public health research priority. AIMS: Building on an earlier cross-sectional study, the current study sought to investigate whether capability-based quality of life changed during the first 5-months of lock-down restrictions in the UK, and whether capability-based quality of life was predictive of future levels of depression and anxiety. METHODS: An initial convenience sample of 594 participants were followed up at three different timepoints spanning a 20-week time-period between March 2020 and August 2020. Participants provided demographic information and completed the Oxford Capabilities Questionnaire - Mental Health (OxCAP-MH), and the Hospital Anxiety and Depression Scale (HADS). RESULTS: The mean scores indicated that levels of both depression and anxiety decreased across the three timepoints, whereas capability-based QoL (as assessed by the OxCAP-MH) decreased over time. Capability-based QoL predicted additional levels of variance in both depression and anxiety levels when time and sociodemographic factors were controlled for. Cross-lagged panel model analyses indicated that capability-based QoL over a month into lockdown restrictions predicted levels of depression and anxiety 5 months into the restrictions. CONCLUSIONS: The study findings suggest that the capability-limiting impact of public health emergencies and related lockdown restrictions are important for understanding peoples' levels of depression and anxiety. The implications that the findings have for the provision of support in the context of public health emergencies and associated restrictions are discussed.

RESUMO

Menu energy labelling has been implemented as a public health policy to promote healthier dietary choices and reduce obesity. However, it is unclear whether the influence energy labelling has on consumer behaviour differs based on individuals' demographics or characteristics and may therefore produce inequalities in diet. Data were analysed from 12 randomized control trials (N = 8508) evaluating the effect of food and drink energy labelling (vs. labelling absent) on total energy content of food and drink selections (predominantly hypothetical) in European and US adults. Analyses examined the moderating effects of participant age, sex, ethnicity/race, education, household income, body mass index, dieting status, food choice motives and current hunger on total energy content of selections. Energy labelling was associated with a small reduction (f2 = 0.004, -50 kcal, p < 0.001) in total energy selected compared to the absence of energy labelling. Participants who were female, younger, white, university educated, of a higher income status, dieting, motivated by health and weight control when making food choices, and less hungry, tended to select menu items of lower energy content. However, there was no evidence that the effect of energy labelling on the amount of energy selected was moderated by any of the participants' demographics or characteristics. Energy labelling was associated with a small reduction in energy content of food selections and this effect was similar across a range of participants' demographics and characteristics. These preliminary findings suggest that energy labelling policies may not widen existing inequalities in diet.

RESUMO

BACKGROUND: Increased weight-related stigma during the COVID-19 pandemic has amplified the need to minimise the impacts on mental wellbeing. We investigated the relationship between the perceived changes in the representation of obesity in the media and mental wellbeing during the pandemic in a sample of people with obesity across 10 European countries. We also investigated the potential moderating effect of loneliness. METHODS: Between September to December 2020 during the COVID-19 pandemic, participants reported data on demographics, mental wellbeing (measured by World Health Organisation Five Wellbeing Index and Patient Health Questionaire-4), loneliness (measured by De Jong Gierveld short scale), and perceived change in the representation of obesity in media (measured by a study-specific question) using the online, cross-sectional EURopean Obesity PatiEnt pANdemic Survey (EUROPEANS). Data were analysed using linear mixed-effects models, controlling for age, gender, body mass index, and shielding status, with random incept for country. RESULTS: The survey was completed by 2882 respondents. Most identified as female (56%) and reported their ethnicity as White or White-mix (92%). The total sample had a mean age of 41 years and a BMI of 35.4 kg/m2. During the peak of the pandemic, compared to pre-pandemic, perceiving more negative representation of people with obesity on social media was associated with worse psychological distress, depression, and wellbeing. Perceiving more positive representation, compared to no change in representation, of people with obesity on television was associated with greater wellbeing, yet also higher psychological distress and anxiety. Loneliness, as a moderator, explained ≤0.3% of the variance in outcomes in any of the models. CONCLUSIONS: Perceiving negative representation of obesity on social media was associated with poorer mental wellbeing outcomes during the pandemic; positive representation on television was associated with both positive and negative mental wellbeing outcomes. We encourage greater media accountability when representing people with obesity.

RESUMO

Research shows cognitive and neurobiological overlap between sign-tracking [value-modulated attentional capture (VMAC) by response-irrelevant, discrete cues] and maladaptive behaviour (e.g. substance abuse). We investigated the neural correlates of sign-tracking in 20 adults using an additional singleton task (AST) and functional magnetic resonance imaging (fMRI). Participants responded to a target to win monetary reward, the amount of which was signalled by singleton type (reward cue: high value vs. low value). Singleton responses resulted in monetary deductions. Sign-tracking-greater distraction by high-value vs. low-value singletons (H > L)-was observed, with high-value singletons producing slower responses to the target than low-value singletons. Controlling for age and sex, analyses revealed no differential brain activity across H > L singletons. Including sign-tracking as a regressor of interest revealed increased activity (H > L singletons) in cortico-subcortical loops, regions associated with Pavlovian conditioning, reward processing, attention shifts and relative value coding. Further analyses investigated responses to reward feedback (H > L). Controlling for age and sex, increased activity (H > L reward feedback) was found in regions associated with reward anticipation, attentional control, success monitoring and emotion regulation. Including sign-tracking as a regressor of interest revealed increased activity in the temporal pole, a region related to value discrimination. Results suggest sign-tracking is associated with activation of the 'attention and salience network' in response to reward cues but not reward feedback, suggesting parcellation between the two at the level of the brain. Results add to the literature showing considerable overlap in neural systems implicated in reward processing, learning, habit formation, emotion regulation and substance craving.

RESUMO

The Postpartum Specific Anxiety Scale [PSAS] was developed and validated as a research tool with a four-factor structure; with predictive validity corroborated in studies examining infant-feeding and maternal bonding outcomes. The PSAS has not been examined in relation to birth experiences. We aimed to confirm the PSAS four-factor structure and examine these domains of anxiety in relation to subjective and objective birth experiences. Postpartum mothers (≤ 12-months; N = 500) completed the PSAS alongside measures of subjective birth satisfaction and objective obstetric interventions/complications. Confirmatory factor analyses [CFA] tested eight models, theoretically derived from the preceding exploratory work. Structural equation modelling [SEM] tested associations between each PSAS factor and birth experience variables in the best-fitting model. An identical 51-item four-factor model fits the data well. SEM analyses revealed associations between lower perceptions of quality of intrapartum care and increased maternal competence and attachment anxieties, practical infant care anxieties, and infant safety and welfare anxieties. High subjective stress and negative emotional response to labour were associated with increased psychosocial adjustment to motherhood anxieties. Specific associations were found between neonatal care unit admission and practical infant care anxieties; and infant asphyxia and infant safety and welfare anxieties. Findings confirm construct and convergent validity of the four-factor PSAS and its use in measuring postpartum anxiety. Unique associations were also identified, indicating specific subjective and objective experiences occurring during birth may elicit a differential anxiety response, in that they are related to specific forms of postpartum anxiety which occur during the first postpartum year.
