Development and initial validation of a hospital stress questionnaire.

Background: Hospitalisation can be a traumatic experience, where inpatients are exposed to an abundance of physical and psychological stressors. Evidence suggests that these hospital-related stressors negatively impact health: a phenomenon known as post-hospital syndrome. The current study aimed to identify hospital-related stressors, and to develop and provide initial validation for a new measure of in-hospital stress. Methods: Measure development occurred in three stages: (i) semi-structured interviews, (ii) item generation, and (iii) pilot testing. Twenty-one patients were interviewed regarding their recent hospital experiences, and a list of hospital-related stressors was produced. These stressors were compiled into a questionnaire and piloted on 200 recent inpatients to provide initial evidence of internal consistency and construct validity. Results: Stressors identified from the interviews captured all relevant questions from three previous hospital stress measures, plus 12 more. The most reported stressor was 'poor sleep'. These hospital-related stressors were developed into 67 questions, forming the Hospital Stress Questionnaire (HSQ). The HSQ showed excellent internal consistency and construct validity, and correlated with feelings of vulnerability and being unprepared to go home. Conclusion: The HSQ is a promising self-report tool for measuring in-hospital stress. Future research ought to investigate its psychometric properties further in larger and more diverse samples. The measure has potential to be used to monitor patient risk of post-hospital syndrome.

Loneliness, sleep and daily stress: Evidence of direct and indirect effects.

This study investigated: i) the effects of loneliness on self-reported sleep outcomes and daily stress/hassles, ii) whether the effects of loneliness on sleep outcomes were mediated through prior-day stress/hassles and iii) if the effects of loneliness on daily stress/hassles were mediated through prior-night sleep measures. Using a 7-day diary design, this study aimed to investigate relationships between loneliness, daily sleep outcomes and daily stress/hassles. Participants (N = 174, Mage 19.95, 86.2% female) completed the UCLA Loneliness Scale once before a 7-day online diary twice per day. Measures of daily stress and hassles were completed before bed and sleep outcomes the following day. Multilevel modelling found higher levels of loneliness were associated with poorer sleep quality, greater pre-sleep arousal, morning tiredness, fewer total hours slept and higher levels of daily stress and hassles across the 7-day study. Loneliness was found also to have indirect effects on sleep quality, pre-sleep arousal and morning tiredness through prior-day daily stress and hassles. In addition, loneliness also had indirect effects on daily stress and hassles through prior night sleep measures. The current findings suggest that interventions aimed at mitigating the effects of loneliness should also incorporate components that target modifiable risk factors such as sleep and stress.

Childhood trauma and suicide risk: Investigating the role of adult attachment.

BACKGROUND: Suicide is a leading cause of death globally and a serious public health concern. Childhood trauma has been found to be associated with adult suicide vulnerability. Recent research has turned attention to investigating the role of attachment in the context of the childhood trauma-adult suicide relationship. The current study investigated for the first time whether attachment influences and moderates the childhood trauma-suicidality relationship, using a daily diary design, in the general population. METHODS: 481 participants completed questionnaires assessing experiences of childhood trauma, attachment patterns, and history of suicidality. 243 participants continued to a daily diary phase where measures of daily stress, defeat and entrapment were completed for 7 consecutive days. RESULTS: Higher levels of childhood trauma were associated with a history of suicide ideation and attempt and also higher levels of daily defeat, entrapment and stress during the 7 day study. Similarly, higher levels of attachment anxiety and avoidance were associated with a history of suicide ideation and attempt together with higher levels of daily defeat, entrapment and stress. However, the effects of childhood trauma on suicide history and on daily suicide vulnerability factors were not moderated by attachment anxiety or avoidance. LIMITATIONS: The measure of childhood trauma was a retrospective self-report tool that may be influenced by memory biases. CONCLUSIONS: Childhood trauma and insecure attachment are implicated in adult suicide risk. Interventions aimed at mitigating the negative effects of childhood trauma and insecure attachment should also incorporate components that target modifiable risk factors such as defeat, entrapment and stress.

Could breaks reduce general practitioner burnout and improve safety? A daily diary study.

BACKGROUND: Rates of burnout are currently at record high levels, and GPs experience higher burnout than many other specialties. Organisational interventions may reduce burnout, but few studies have investigated these in primary care. AIM: The current study investigated whether breaks, both with and without social interactions, were associated with burnout and patient safety perceptions in GPs. DESIGN: A within-subjects, interval contingent, quantitative daily diary design. SETTING: UK GP practices. METHOD: Participants completed questionnaires at baseline measuring demographic variables, burnout and patient safety perceptions. They then completed a questionnaire in the evening each day for a week which captured whether they had taken a break that day, whether it involved a positive social interaction, burnout (comprising subscales of disengagement and exhaustion), positive and negative affect and patient safety perceptions. The data were analysed using hierarchical linear modelling to assess same-day and next-day associations. RESULTS: We included 241 responses from 58 GPs for analysis. Taking at least one break (involving any or no social interactions) was associated with lower disengagement that day and lower exhaustion the next day. Taking at least one break involving a positive interaction was associated with 1) lower disengagement, exhaustion, overall burnout and negative affect on the same day, as well as higher positive affect and improved perceptions of patient safety, and 2) lower exhaustion and improved patient safety perceptions on the next day. CONCLUSION: Organizing daily team or practice breaks where staff can socialise may help to reduce burnout and improve perceptions of patient safety.

Selective outcome reporting in trials of behavioural health interventions in health psychology and behavioural medicine journals: a review.

Selective outcome reporting can result in overestimation of treatment effects, research waste, and reduced openness and transparency. This review aimed to examine selective outcome reporting in trials of behavioural health interventions and determine potential outcome reporting bias. A review of nine health psychology and behavioural medicine journals was conducted to identify randomised controlled trials of behavioural health interventions published since 2019. Discrepancies in outcome reporting were observed in 90% of the 29 trials with corresponding registrations/protocols. Discrepancies included 72% of trials omitting prespecified outcomes; 55% of trials introduced new outcomes. Thirty-eight percent of trials omitted prespecified and introduced new outcomes. Three trials (10%) downgraded primary outcomes in registrations/protocols to secondary outcomes in final reports; downgraded outcomes were not statistically significant in two trials. Five trials (17%) upgraded secondary outcomes to primary outcomes; upgraded outcomes were statistically significant in all trials. In final reports, three trials (7%) omitted outcomes from the methods section; three trials (7%) introduced new outcomes in results that were not in the methods. These findings indicate that selective outcome reporting is a problem in behavioural health intervention trials. Journal- and trialist-level approaches are needed to minimise selective outcome reporting in health psychology and behavioural medicine.

A registered report survey of open research practices in psychology departments in the UK and Ireland.

Open research practices seek to enhance the transparency and reproducibility of research. While there is evidence of increased uptake in these practices, such as study preregistration and open data, facilitated by new infrastructure and policies, little research has assessed general uptake of such practices across psychology university researchers. The current study estimates psychologists' level of engagement in open research practices across universities in the United Kingdom and Ireland, while also assessing possible explanatory factors that may impact their engagement. Data were collected from 602 psychology researchers in the United Kingdom and Ireland on the extent to which they have implemented various practices (e.g., use of preprints, preregistration, open data, open materials). Here we present the summarized descriptive results, as well as considering differences between various categories of researcher (e.g., career stage, subdiscipline, methodology), and examining the relationship between researcher's practices and their self-reported capability, opportunity, and motivation (COM-B) to engage in open research practices. Results show that while there is considerable variability in engagement of open research practices, differences across career stage and subdiscipline of psychology are small by comparison. We observed consistent differences according to respondent's research methodology and based on the presence of institutional support for open research. COM-B dimensions were collectively significant predictors of engagement in open research, with automatic motivation emerging as a consistently strong predictor. We discuss these findings, outline some of the challenges experienced in this study, and offer suggestions and recommendations for future research. Estimating the prevalence of responsible research practices is important to assess sustained behaviour change in research reform, tailor educational training initiatives, and to understand potential factors that might impact engagement.

Effects of a self-affirmation intervention on responses to bowel cancer screening information.

OBJECTIVE: To investigate the effect of two brief self-affirmation interventions, immediately prior to reading standard information about bowel cancer screening, on state anxiety, message acceptance and behavioural intention to screen for bowel cancer. METHODS: 242 adults aged 49 were randomised to one of two self-affirmation interventions (health or values) or one of two control conditions, before reading an NHS England bowel cancer screening leaflet. Participant friend and family history of bowel cancer, state anxiety, message acceptance, behavioural intention to screen, trait self-esteem and spontaneous self-affirmation were measured. Data were analysed using between-participants analysis of variance, planned contrasts and moderated regression. RESULTS: No main effects of experimental condition on levels of state anxiety, message acceptance and behavioural intention were found. However, planned contrasts showed participants who self-affirmed about their health or values (conditions-collapsed) were significantly less anxious and reported significantly higher behavioural intentions compared to participants in the controls (conditions-collapsed). Irrespective of condition, higher levels of spontaneous self-affirmation and trait self-esteem were correlated with lower anxiety, higher intentions, and message acceptance. CONCLUSION: There was some evidence of the effect of health-based self-affirmation on lowering anxiety; however, further research is needed to explore the effectiveness of different self-affirmation interventions in larger samples.

The effects of childhood trauma on stress-related vulnerability factors and indicators of suicide risk: An ecological momentary assessment study.

BACKGROUND: Childhood trauma is experienced by approximately one third of young people in the United Kingdom and has been shown to confer an increased risk for mental health difficulties in adulthood. Understanding the associations between these factors before negative health outcomes manifest in adulthood is imperative to help inform the development of interventions. The aims of this study were two-fold; first, to investigate the effects of childhood trauma on daily stress-related vulnerability factors over a period of 7 days and to test whether any observed relationships were moderated by protective or risk factors. Second, to explore the indirect effects of childhood trauma on reasons for living, optimism, daily suicide ideation, defeat and entrapment through the daily stress-related vulnerability factors. METHODS: 212 participants were recruited to an ecological momentary assessment study to complete three diaries per day for a 7-day period. Participants completed daily measures of stress, hassles, executive functioning, impulsivity, sleep quality (stress-related vulnerability factors) as well as measures of reasons for living, optimism, daily thoughts of suicide, defeat and entrapment. The Childhood Trauma Questionnaire was also completed at baseline. RESULTS: Analyses found that childhood trauma was significantly associated with higher scores on the daily stress-related vulnerability factors and positively related to each of the daily indicators of suicide risk. The study also uncovered key pathways whereby trauma had indirect effects on reasons for living, optimism, daily thoughts of suicide, defeat and entrapment through executive functioning, impulsivity, sleep quality and stress. LIMITATIONS: The measures of executive function and sleep were self-reported and future research ought to replicate the current findings using more objective methods. DISCUSSION: The findings from this study highlight the complexity of childhood trauma and its damaging effects on stress-related vulnerability factors and poorer mental health outcomes. Greater understanding of pathways by which trauma may impact later health outcomes is essential for development of interventions.

COVID Protection Behaviors, Mental Health, Risk Perceptions, and Control Beliefs: A Dynamic Temporal Network Analysis of Daily Diary Data.

BACKGROUND: To control infections, behavioral non-pharmaceutical interventions (NPIs) such as social distancing and hygiene measures (masking, hand hygiene) were implemented widely during the COVID-19 pandemic. At the same time, adherence to NPIs has also been implied in an increase in mental health problems. However, the designs of many existing studies are often poorly suited to disentangle complex relationships between NPI adherence, mental health symptoms, and health-related cognitions (risk perceptions, control beliefs). PURPOSE: To separate between- and temporal within-person associations between mental health, health-related cognitions, and NPI adherence. METHODS: Six-month ecological momentary assessment (EMA) study with six 4-day assessment bouts in 397 German adults. Daily measurement of adherence, mental health symptoms, and cognitions during bouts. We used dynamic temporal network analysis to estimate between-person, as well as contemporaneous and lagged within-person effects for distancing and hygiene NPIs. RESULTS: Distinct network clusters of mental health, health cognitions, and adherence emerged. Participants with higher control beliefs and higher susceptibility were also more adherent (between-person perspective). Within-person, similar findings emerged, additionally, distancing and loneliness were associated. Lagged findings suggest that better adherence to NPIs was associated with better mental health on subsequent days, whereas higher loneliness was associated with better subsequent hygiene adherence. CONCLUSIONS: Findings suggest no negative impact of NPI adherence on mental health or vice versa, but instead suggest that adherence might improve mental health symptoms. Control beliefs and risk perceptions are important covariates of adherence-both on between-person and within-person level.

Adhering to COVID protective behaviors might be less detrimental for mental health than some previous claims: Over 6 months in 2021­2022, adults from Germany who adhered to COVID protection recommendations (mask-wearing, hand hygiene, social distancing) on any one day reported better mental health the following days.

Effects of a modified invitation letter to follow-up colonoscopy for bowel cancer detection.

OBJECTIVE: To investigate whether modifications made to the current National Health Service (NHS) invitation letter for follow-up colonoscopy examination affect participant state anxiety and behavioural intentions to attend. METHODS: Five hundred and thirty-eight adults of bowel cancer-eligible screening age (56-74) were randomized to receive the current NHS invitation letter or the modified version of the letter as a hypothetical scenario. Modifications to the letter included fewer uses of the term cancer and awareness of alternative screening options. The history of the colonoscopy invitation, anticipated state anxiety, behavioural intention to attend the nurse appointment, and colonoscopy concerns upon reading the letter were measured. RESULTS: Behavioural intentions were high in both conditions; however, participants reading the current letter reported significantly higher behavioural intentions compared to the modified letter. There was no main effect of previous invite status or interaction between previous invite status and letter condition on behavioural intentions. However, the effect of the letter on levels of anxiety depended on the participant's invitation history. Those never invited for a colonoscopy were more anxious when reading the modified letter compared to the current letter. Conversely, previous colonoscopy invitees were less anxious following reading the modified letter than those reading the current letter. Those never invited for a colonoscopy were more concerned about embarrassment and test invasiveness. All findings remained the same when controlling for age and education. CONCLUSION: Modifications to the invitation letter were not beneficial to levels of screening intention or anxiety.

Social network size moderates the association between loneliness and cardiovascular reactivity to acute stress.

Loneliness and objective measures of social isolation (e.g., social network size) have been associated with increased risk of cardiovascular disease (CVD). However, the evidence is mixed and the precise causal mechanisms remain unclear. Cardiovascular reactivity (CVR) to acute stress has been posited as a proposed mechanism. This study aimed to investigate: (i) effects of loneliness and social isolation on CVR to stress and, (ii) whether the loneliness - CVR relationship was moderated by social network size. Two hundred and six participants from the Pittsburgh Cold Study underwent a modified version of the Trier Social Stress Task. Cardiovascular measures of systolic (SBP) and diastolic blood pressure (DBP) and heart rate (HR) were taken throughout the laboratory stress trial. Hierarchical regression analyses found that social network size was positively associated with DBP reactivity (ß = 0.19 95 % CI [0.05, 0.29] p = 0.005), while loneliness was not. In addition, social network size moderated the loneliness - DBP reactivity relationship such that a higher number of outer social network ties were beneficial at lower levels of loneliness but not higher. The current study contributes new evidence linking loneliness and social network size to cardiovascular psychophysiology but raises questions about the loneliness - CVD relationship. The findings confirm the importance of social network size and highlight that the characteristics of the networks may be more important than the number of networks.

Curb the spread: Leveraging intensive longitudinal data to unravel within- and between-person processes in adherence to nonpharmaceutical interventions during COVID-19.

OBJECTIVES: Adhering to behavioral recommendations and nonpharmaceutical interventions (NPIs) is a key to control COVID-19 infection rates. However, rates have decreased globally, and potentially modifiable determinants of ongoing adherence and their interaction with social and physical momentary environments are still poorly understood. Here, we comprehensively examine within-person variations and between-person differences in known behavioral determinants (capability and motivation), as well as the moderating role of situational variable environmental factors (opportunity) in predicting adherence to hygiene and social distancing behaviors. METHOD: Ecological momentary assessment study over 6 months with monthly assessment bouts (4 days each and five daily assessments) in 623 German adults. Repeated daily assessments of capability, opportunity, motivation, and behavior (COM-B) model factors. Bayesian multilevel logistic regression models were estimated to examine main effects of COM-B factors and moderating effects of momentary environmental factors. RESULTS: Momentary adherence to NPIs was predicted by within-person changes in COM-B factors (motivation: intentions, goal conflict, and control beliefs; opportunities: regulations and norms). Between-person differences in capabilities (habit strength) and motivation (intentions and control beliefs) predicted adherence across situations. Situation-specific environmental factors moderated the motivation-behavior association (regulation measures increased; goal conflict and nonadherent others decreased the association). CONCLUSIONS: Individual momentary (within-person) and stable (between-person) motivation indicators predicted adherence. However, situational environmental factors such as regulations or norms have strong main effects and moderate the motivation-behavior translation. These findings have policy implications, supporting recent claims to not rely on the narrative of "personal responsibility," but instead combine health education measures to increase individual motivation with consistent regulation.

Social Norms in Cervical Cancer Screening.

Cancer screening aims to check the body for cancer before symptoms develop. Social norms theory suggests people falsely perceive the attitudes and/or behaviours of similar others to be different from their own and correcting these perceptions can lead to behaviour change. Across two studies, we tested if women underestimate peer levels of cervical screening behaviour and whether a social norms manipulation increases intention to attend cervical cancer screening. In study 1, participants completed a survey on cervical cancer screening norms. In study 2, participants were randomised to receive no norm information, norm information, or norm information plus statement on value of norms in decision making. In study 1, participant estimates of peer level of cervical screening behaviour were significantly lower than nationally reported levels. In study 2, a social norm plus value statement intervention led to stronger intentions to attend screening. This effect was consistent across demographic factors and screening status. Participants significantly underestimate rates of cervical screening behaviour in their peers. A brief, online social norms plus values manipulation increased intentions to attend cervical cancer screening across all groups.

Effects of childhood trauma on sleep quality and stress-related variables in adulthood: evidence from two multilevel studies.

Childhood trauma has been found to have serious negative consequences for mental and physical health. However, the precise mechanisms through which trauma influences health outcomes are unclear. Childhood trauma-related disruptions to sleep in adulthood represent an important potential mechanism. Two 7-day multilevel studies investigated the effects of childhood trauma on daily sleep outcomes and stress-related variables and whether the effects of trauma on sleep outcomes were mediated through these stress-related variables (or vice versa). Participants completed the Childhood Trauma Questionnaire before a 7-day online daily diary study. Measures of daily stress, perseverative cognition, and sleep were completed daily. Multi-level modelling found that higher levels of childhood neglect were associated with poorer daily sleep quality, shorter sleep duration, longer sleep onset latency, and higher daily stress and rumination levels. Higher childhood abuse was associated with shorter sleep duration, greater morning tiredness, and higher levels of daily stress, rumination, and worry. Childhood trauma was found also to have bidirectional, indirect effects on sleep quality and morning tiredness through daily stress-related variables. The current findings suggest that interventions aimed at mitigating the negative effects of childhood trauma should also incorporate components that target modifiable risk factors, such as sleep, stress, worry, and rumination.

Evaluation of the reboot coaching workshops among urology trainees: A mixed method approach.

Background: Urology trainees experience high burnout, and there is an urgent need for acceptable and effective interventions. The current study evaluated Reboot coaching workshops (Reboot-C), a tailored intervention based on cognitive-behavioural principles, with urology trainees. Objective: Our primary objective was to evaluate the acceptability of Reboot-C among urology trainees. In addition, this study aimed to investigate whether there were changes in confidence, resilience, depression and burnout levels. Materials and method: A single-arm design was used, including pre- and post-online questionnaires and semi-structured interviews. Result: Twenty-one urology trainees replied to the survey, attended both Reboot-C workshops and responded to the post-intervention questionnaire. Thirteen of 21 (61%) urology trainees participated in the interview. Participating in Reboot-C was associated with significant improvements in resilience and confidence and a significant reduction in burnout. However, there was no significant reduction in depression. Qualitative data indicated that Reboot was acceptable and helped participants develop useful skills. Conclusion: These findings pave the way for more conclusive studies on the efficacy of Reboot-C for surgeons.

Understanding a constellation of eight COVID-19 disease prevention behaviours using the COM-B model and the theoretical domains framework: a qualitative study using the behaviour change wheel.

Background: The use of behavioural science and behaviour change within local authorities and public health has supported healthful change; as evidenced by its importance and contribution to reducing harm during the COVID-19 pandemic. It can provide valuable information to enable the creation of evidence-based intervention strategies, co-created with the people they are aimed at, in an effective and efficient manner. Aim: This study aimed to use the COM-B model to understand the Capability, Opportunity and Motivation of performing a constellation of eight COVID-19 disease prevention behaviours related to the slogans of 'Hands, Face, Space, Fresh Air'; 'Find, Isolate, Test, (FIT), and Vaccinate' in those employed in workplaces identified as high risk for transmission of the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) to support intervention development. Methods: This qualitative study recruited twenty-three participants (16 female, 7 male), who were interviewed from three environments (schools, care homes, warehouses) across three local authorities. Semi-structured interviews were analysed using thematic analysis. Findings: Ten core themes were identified inductively; (1) knowledge and skills, (2) regulating the behaviour, (3) willingness to act, (4) necessity and concerns, (5) emotional impact, (6) conducive environment, (7) societal influence, (8) no longer united against COVID-19, (9) credible leadership, and (10) inconsistent adherence to COVID-19 prevention behaviours. Themes were then deductively mapped to the COM-B model of behaviour change and the theoretical domains framework and a logic model using the behaviour change wheel (BCW) was produced to inform intervention design. Conclusion: This study offers a novel approach to analysis that has included eight behaviours within a single thematic analysis and COM-B diagnosis. This will enable local authorities to direct limited resources to overarching priorities. Of key importance, was the need for supportive and credible leadership, alongside developing interventions collaboratively with the target audience. COVID-19 has had an emotional toll on those interviewed, however, promoting the value of disease prevention behaviours, over and above their costs, can facilitate behaviour. Developing knowledge and skills, through education, training, marketing and modelling can further facilitate behaviour. This supports guidance produced by the British Psychological Society COVID-19 behavioural science and disease prevention taskforce.

Do British and Chinese adolescents snack for different reasons? A cross-country study using the Theory of Planned Behaviour and eating styles.

Snacking is prevalent in adolescents and can have significant health impacts, but there is considerable individual and cross-country variation in determinants on adolescent snacking. The present study examined the role of eating styles (i.e. restrained eating, emotional eating, external eating, mindful eating) and the constructs of an extended Theory of Planned Behaviour (TPB) (i.e. attitudes, subjective norms, perceived behavioural control, habit strength) in predicting adolescent snacking, and the moderating effects of country. A survey was completed by adolescents aged 16-19 years from China (N = 182; mean age = 16.13, SD = 0.87) and England (N = 96; mean age = 17.04, SD = 0.74). Compared to British adolescents, Chinese adolescents showed higher restrained eating (p = .009), lower external eating (p = .004), less positive attitudes (p < .001) and subjective norms (p = .007) to, and less strong habit strength (p = .005) for unhealthy snacking. Mindful eating significantly predicted lower consumption of unhealthy snacks (p = .008) and beverages (p = .001), while restrained eating predicted higher consumption of fruit (p < .001) and vegetables (p < .001), regardless of country. Country showed significant moderating effects of TPB constructs on unhealthy beverages (p = .008) and fruit (p < .001) consumption, and effects on unhealthy snack (p = .023) and vegetable (p = .015) consumption approaching significance. Subjective norms predicted unhealthy snacking frequency regardless of country (p = .001). Habit strength predicted consumption of beverages (p < .001) and fruit (p < .001) only in English adolescents. Mindful eating may be a positive intervention approach to help reduce adolescent unhealthy snacking. TPB-based snacking interventions should carefully consider the country context. Acknowledging country-specific determinants of snacking are recommended.

A latent class analysis using the integrated motivational-volitional model of suicidal behaviour: Understanding suicide risk over 36 months.

BACKGROUND: The use of latent class analysis (LCA) to understand suicide risk is often not guided by theoretical frameworks. This study used the Integrated Motivational-Volitional (IMV) Model of Suicidal Behaviour to inform the classification of subtypes of young adults with a suicidal history. METHODS: Data from young adults in Scotland (n = 3508) were used in this study including a subgroup of participants (n = 845) with a history of suicidality. LCA using risk factors from the IMV model was conducted on this subgroup, and the subgroups and non-suicidal control group were compared. Trajectories of suicidal behaviour over 36 months was compared between the classes. RESULTS: Three classes were identified. Class 1 (62 %) had low scores on all risk factors, Class 2 (23 %) had moderate scores, and Class 3 (14 %) had high scores on all risk factors. Those in Class 1 had a stable low risk of suicidal behaviour, while those in Class 2 and 3 showed marked variation over time, although Class 3 had the highest risk across all timepoints. LIMITATIONS: The rate of suicidal behaviour in the sample was low, and differential dropout may have impacted the findings. CONCLUSIONS: These findings suggest that young adults can be classified into different profiles based on suicide risk variables derived from the IMV model, which still distinguishes them 36 months later. Such profiling may help determining who is most at risk for suicidal behaviour over time.

Daily stress and eating behaviors in adolescents and young adults: Investigating the role of cortisol reactivity and eating styles.

Stress-related eating has been well documented in previous literature. However, there is limited research investigating the role of cortisol reactivity in daily stress-eating associations in samples of adolescents and young adults. 123 participants completed a baseline questionnaire and the Trier Social Stress Test in groups. Four saliva samples were taken at - 10, + 00, + 10 and + 40 min during the stress-induction task. Following this, participants completed an online daily diary each evening for 14 consecutive days to record daily stress and between-meal snack consumption. Multilevel modelling indicated that daily stress was positively associated with daily snack intake, particularly for ego-threatening and work/academic stressors. Emotional and external eating styles were found to moderate the stress-snacking relationship. Cortisol reactivity also moderated stress-eating associations, such that as cortisol reactivity levels increased from lower to higher levels, the impact of stress on eating decreased. The current findings highlight the importance of cortisol reactivity status and eating styles in understanding the complex relationship between daily stress and eating behavior in adolescents and young adults. Future research should continue investigating stress-eating associations in these groups and explore the role of other aspects of hypothalamic-pituitary-adrenal axis functioning.

Open Science in Health Psychology and Behavioral Medicine: A Statement From the Behavioral Medicine Research Council.

ABSTRACT: Open Science practices include some combination of registering and publishing study protocols (including hypotheses, primary and secondary outcome variables, and analysis plans) and making available preprints of manuscripts, study materials, de-identified data sets, and analytic codes. This statement from the Behavioral Medicine Research Council (BMRC) provides an overview of these methods, including preregistration; registered reports; preprints; and open research. We focus on rationales for engaging in Open Science and how to address shortcomings and possible objections. Additional resources for researchers are provided. Research on Open Science largely supports positive consequences for the reproducibility and reliability of empirical science. There is no solution that will encompass all Open Science needs in health psychology and behavioral medicine's diverse research products and outlets, but the BMRC supports increased use of Open Science practices where possible.
