COVID-19 pandemic and comfort food consumption based on gender in a Brazilian sample: which variables are related to this behavior?

PurposeThis study aims to identify comfort food (CF) consumption and its associated factors during the pandemic period. The study also involves an online survey conducted five months after the quarantine started in Brazil. Design/methodology/approachData on lifestyle, eating habits and anthropometric data were collected before and during the pandemic, and the differences in these habits were analyzed. Univariate and multivariate logistic regression models were performed to identify predictors of CF consumption by gender. FindingsA total of 1,363 individuals were included in the sample, with a median age of 31 years old, of whom 80.3% were women. Since individuals were free to respond about the food consumed without predetermined categories, it was possible to carry out a faithful assessment of the occurrence of this behavior. At the same time, allowing the subjectivity and symbolism inherent to the concept of CF to be embraced. CF consumption was present for 54%, with "sweets" being the most mentioned group by both genders. The factors associated with CF consumption in women during the pandemic were increased snacking, increased bread, candies and alcoholic beverage intake, increased time spent at work, worsened sleep quality, reduced meals, perceived stress (PS), emotional eating (EE), age and increased frequency of meat intake. In men, the predictors for CF consumption were remote full-time work/study, PS, EE and early waking time. For both genders, CF consumption during the pandemic period was associated with PS and EE. Originality/valueThis study provides an important overview of the possible contributions of the pandemic on behaviors and food choices related to the consumption of CF in Brazilians. This information is valuable to support further studies to investigate and treat the impacts of the pandemic on lifestyle, eating habits and behavior, mental health and other factors in the postpandemic period.

Crowdfunding platforms: a systematic literature review and a bibliometric analysis

Due to the financial crisis caused by the COVID-19 pandemic, entrepreneurs and small businesses have had multiple difficulties accessing conventional types of financing. Crowdfunding platforms have gained popularity as an alternative means of online financing. The main objective of this research is to analyze the most important articles that may influence future studies on crowdfunding platforms in Latin America. This article analyzes the Scopus and Web of Science databases considering three of the four categories of crowdfunding based on capital flows: Reward, Equity, and Lending, using a systematic review of the literature and bibliometric analysis. This research resulted in a total of 1032 articles which, after applying the appropriate criteria, resulted in 55 selected articles. The results show that the number of studies conducted in the field of crowdfunding platforms is increasing. Crowdfunding platforms provide a great opportunity for entrepreneurs to obtain alternative financing and a new way for investors to invest their capital. Future lines of research include conducting studies that involve a stronger focus on the technology used in crowdfunding platforms. With systematized access to information, the different actors can understand how the dynamics of crowdfunding platforms can stimulate the development of business projects, as well as the decision-making factor when investing. This document is of great interest to researchers and professionals who wish to increase their knowledge of crowdfunding platforms, especially those of Reward, Equity, and Lending, in addition to gaining knowledge on relevant conclusions and suggestions for future research. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Mediating role of resilience in relationship between occupational stress and depression of staff of centers for disease control and prevention.

[Background] Since the outbreak of the COVID-19 epidemic, staff of the centers for disease control and prevention (CDC) have been burdened with heavy epidemic prevention control, and excessive occupational stress can cause depression and other psychological problems. [Objective] To explore the status of occupational stress, resilience, and depression of CDC staff and potential relationships between them. [Methods] From December 2020 to April 2021, a survey was conducted at provincial and municipal levels, and the stratified cluster sampling method was used at county (district) level to select a total of 3 514 samples. Their occupational stress, resilience, and depression status were evaluated using the Chinese Effort-Reward Imbalance Scale (ERI), the Chinese Connor-Davidson Resilience Scale (CD-RISC), and the Patient Health Questionnaire (PHQ-9). Independent sample t test, analysis of variance, chi2 test, Pearson correlation analysis, and mediation test (structural equation model) were conducted. [Results] The positive rate of occupational stress was 34.29% in the CDC staff, the resilience score was 66.28+/-15.32, and the positive rate of depression was 48.58%. Significant differences were found in the positive rates of occupational stress among different groups of gender, age, education background, marital status, administrative duty, weekly exercise frequency, chronic disease prevalence, and participation in epidemic control (P < 0.05);in the resilience scores among different groups of gender, age, administrative duty, weekly exercise frequency, chronic disease prevalence, and participation in epidemic control (P < 0.05);in the positive rates of depression among different groups of gender, age, educational background, personal monthly income, weekly exercise frequency, chronic disease prevalence, and participation in epidemic control (P < 0.05). Occupational stress was negatively correlated with resilience (r=-0.165, P < 0.01). Resilience was negatively correlated with depression (r=-0.383, P < 0.01). Occupational stress was positively correlated with depression (r=0.343, P < 0.01). The structural equation embracing a partial mediating effect of resilience on the relationship occupational stress and depression was established, and the partial mediating effect was 0.039, accounting for 10.46% of the total effect. [Conclusion] High positive rates of occupational stress, reduced resilience, and depression are shown among CDC staff in the context of the COVID-19 epidemic, and resilience partially mediates the effect of occupational stress on depression. The study findings suggest that improving resilience may reduce occupational stress and depression in CDC staff.Copyright © 2022, Shanghai Municipal Center for Disease Control and Prevention.

Occupational stress and its influencing factors of primary health care workers during COVID-19.

[Background] Since the outbreak of COVID-19, primary health care workers have been facing un-precedented work pressure, and their occupational stress should be taken seriously. [Objective] To analyze the occupational stress situation and its influencing factors of primary health care workers in Guangdong Province, and to propose targeted interventions. [Methods] Using a multi-stage stratified random sampling method, each prefecture-level city in Guangdong Province was classified into "good", "medium", or "poor" category based on its gross domestic product (GDP) in 2019 released by the Guangdong Provincial Bureau of Statistics. In September 2021, four primary health care institutions were randomly selected from each stra-tum, and a total of 1 327 staff members were selected for the study. The Core Occupational Stress Scale (COSS) and a basic information questionnaire designed by the authors were used. Mann-Whitney U test was used to compare the means between two groups, and Kruskal-Walis H test was used to compare the means among multiple groups. The comparison of categorical data was performed by trend chi2 test or Pearson chi2 test;the analysis of factors influencing occupational stress was performed by dichotomous multiple logistic regression analysis. [Results] There were 365 health care workers reporting occupational stress in this survey, and the positive rate of occupational stress was 27.5%. The total occupational stress score in M (P25, P75) and the scores of social support, organization and reward, demand and effort, and control were 45.0 (40.0, 50.0), 20.0 (17.0, 21.0), 14.0 (12.0, 17.0), 12.0 (10.0, 15.0), and 5.0 (4.0, 6.0), re-spectively. The results of dichotomous multiple logistic regression analysis showed that high education, low income, doctor positions, long working hours in a day, and shift work were associated with the occurrence of reporting occupational stress (P < 0.05). [Conclusion] Education, average monthly income, job category, daily working hours, and shifts are factors influencing the occurrence of reporting occupational stress in primary health care workers;targeted interventions should be implemented to reduce their occupational stress levels.Copyright © 2023, Shanghai Municipal Center for Disease Control and Prevention.

The effectiveness of financial incentives for COVID-19 vaccination: A systematic review.

Financial incentives are a controversial strategy for increasing vaccination. In this systematic review, we evaluated: 1) the effects of incentives on COVID-19 vaccinations; 2) whether effects differed based on study outcome, study design, incentive type and timing, or sample sociodemographic characteristics; and 3) the cost of incentives per additional vaccine administered. We searched PubMed, EMBASE, Scopus, and Econlit up to March 2022 for terms related to COVID, vaccines, and financial incentives, and identified 38 peer-reviewed, quantitative studies. Independent raters extracted study data and evaluated study quality. Studies examined the impact of financial incentives on COVID-19 vaccine uptake (k = 18), related psychological outcomes (e.g., vaccine intentions, k = 19), or both types of outcomes. For studies of vaccine uptake, none found that financial incentives had a negative effect on uptake, and most rigorous studies found that incentives had a positive effect on uptake. By contrast, studies of vaccine intentions were inconclusive. While three studies concluded that incentives may negatively impact vaccine intentions for some individuals, they had methodological limitations. Study outcomes (uptake versus intentions) and study design (experimental versus observational frameworks) appeared to influence results more than incentive type or timing. Additionally, income and political affiliation may moderate responses to incentives. Most studies evaluating cost per additional vaccine administered found that they ranged from $49-75. Overall, fears about financial incentives decreasing COVID-19 vaccine uptake are not supported by the evidence. Financial incentives likely increase COVID-19 vaccine uptake. While these increases appear to be small, they may be meaningful across populations.

Increased consumption despite fewer occasions: A longitudinal analysis of COVID-19 lockdown effects on soft drink consumption in England.

We examined the impact of a COVID-19 lockdown in England on the frequency of consumption occasions and amount of soft drinks consumed. Beverage consumption is strongly associated with specific, often social, consumption situations (e.g., going out). We reasoned that lockdown would affect consumption behaviour because it removed typical soft drink consumption situations. Specifically, we hypothesised that soft drink consumption occasions and amount would be reduced during lockdown compared to before and after lockdown, especially in typical soft drink consumption situations. In two surveys (Dec. 2020 and May 2021) among the same participants (N = 211, N = 160; consuming soft drinks at least once/week), we assessed the frequency of soft drink and water consumption occasions before, during, and after the Nov./Dec. 2020 lockdown, across typical soft drink and water drinking situations. This presents a detailed picture of the situations in which participants drink soft drinks and water, and how this was affected by a lockdown. We also assessed the daily amount of soft drinks and water consumed in each period, and perceived habitualness of drinking soft drinks and water. As predicted, participants reported fewer occasions of drinking soft drinks during lockdown compared to before and after, especially in typical soft drink consumption situations. Unexpectedly, however, the daily amount of soft drinks consumed increased during lockdown, compared to before and after, especially among participants with stronger perceived habitualness of soft drink consumption. Exploratory analyses suggest that during lockdown, participants increased their soft drink consumption at home. Water consumption, on the other hand, was not systematically affected by the lockdown. These findings suggest that even if some typical consumption situations disappear, consumption may be hard to disrupt if the behaviour is rewarding.

Work Ability, Work-Related Health, and Effort–Reward Imbalance: A Cross-Sectional Study among University Staff during the COVID-19 Pandemic in Thailand

During the COVID-19 pandemic, university policies and public health measures resulted in university staff facing hazardous work environments and psychological health problems. This cross-sectional study aimed to analyze the association between sociodemographic characteristics, health conditions, work-related health, effort and reward imbalance (ERI), and work ability among university staff in southern Thailand. Data were collected using stratified random sampling of 381 participants between April and September 2022. Descriptive statistics and binary logistic regression analyses were used to examine the associations between the variables. The majority of the participants were female (63.5%) and aged below 45 years old (52%). Nearly 70% of the participants reported the absence of non-communicable diseases (NCDs), while half of them were overweight, and 54.9% had an effort–reward ratio (ERR) greater than one. Most participants reported good-to-excellent work ability (82.4%). The probability of having poor-to-moderate work ability was higher among staff working from home (adj. OR = 2.4;95% CI: 1.3, 4.6), those with NCDs (adj. OR = 3.5;95% CI: 2.0, 6.4), those who followed poor health behaviors (adj. OR = 2.6;95% CI: 1.4, 4.9), and those who had an ERR greater than one (adj. OR = 2.8;95% CI: 1.5, 5.6). In conclusion, the majority of university staff in southern Thailand had good-to-excellent work ability. Work ability was associated with the presence of NCDs, poor health behavior, working from home, and ERI. Therefore, universities should create suitable occupational health programs and resources to mitigate the negative effects of work conditions, including ERI, and promote healthy behaviors for their staff during the COVID-19 pandemic and future disasters.

Psychosocial Work Stress and Occupational Stressors in Emergency Medical Services.

Emergency medical service (EMS) professionals often experience work stress, which escalated during COVID-19. High job demand in the EMS profession may lead to progressive decline in physical and mental health. We investigated the prevalence of psychosocial job stress in the three levels of EMS: basic, advanced, and paramedic, before and during the COVID-19 pandemic. EMS professionals (n = 36) were recruited from EMS agencies following the Institutional Review Board approval. Participants took surveys on demographics, personal characteristics, chronic diseases, and work schedules. Job stress indicators, namely the effort-reward ratio (ERR) and overcommitment (OC), were evaluated from survey questionnaires using the effort-reward imbalance model. Associations of job stress indicators with age, sex, body mass index, and working conditions were measured by logistic regression. Psychosocial work stress was prevalent with effort reward ratio > 1 in 83% of participants and overcommitment scores > 13 in 89% of participants. Age, body mass index, and work hours showed strong associations with ERR and OC scores. The investigation findings suggested that a psychosocial work environment is prevalent among EMS, as revealed by high ERR, OC, and their correlation with sleep apnea in rotating shift employees. Appropriate interventions may be helpful in reducing psychosocial work stress in EMS professionals.

Sensitivity of the reward system in post-COVID-fatigue

Background: The health consequences of the SARS-CoV-2 pandemic are dominating the international healthcare systems. More than 15% of patients with supposedly mild SARS-CoV-II disease develop persisting symptoms (Sudre et al., 2021). In addition to known internal limitations, such as respiratory distress or tachycardia, severe neurological deficits are prominent. For example, fatigue persisting for months, cognitive impairment, and a marked increase in daytime sleepiness, sometimes accompanied by an inability to work, are described (Taquet et al., 2021). Previous research indicates that hospitalized patients suffering from COVID-19 often develop fatigue or muscle weakness (63%), difficulties in sleep (26%) and psychiatric disorders, such as anxiety and depression (23%) (Taquet et al., 2021). This constellation of symptoms can lead to severe limitations in the everyday lives of the people concerned. The pathophysiology of this multifaceted neurological and dysautonomic symptom complex is not yet understood but now becoming the focus of interdisciplinary research in the context of the global pandemic. A similar disease is chronic fatigue syndrome (CFS). Affected patients suffer from very comparable limitations, especially persistent fatigue. Evidence suggests an alteration of the specific cerebral reward system in CFS, an important modulator of learning processes involved in various homeostatic regulatory processes (Wylie and Flashman, 2017). Objective(s): Based on the similarity of symptoms in CFS and Post-COVID fatigue this study aims to investigate whether a reduced sensitivity of the reward system in the context of postviral fatigue syndrome is present. We hypothesize that the sensitivity of the reward system in patients with Post-COVID syndrome is reduced compared to healthy adults. Method(s): 24 subjects with a diagnosed Post-COVID syndrome and 20 healthy individuals between the age of 18-55 without relevant neurological or psychiatric disorders in the medical record participated in the study. Magnetoencephalography and electroencephalography were used for the characterization of the reward system during the monetary incentive delay task, a classic paradigm used in existing publications (Frank et al., 2004;Opitz et al., 2022). In addition, standardized questionnaires were used to obtain further information about the included individuals' living conditions and the severity of symptoms. Result(s) and Conclusion(s): Results of the study will help to better characterize reward network changes in the context of fatigue symptoms to open up therapeutic options for medication or psychotherapeutic interventions. Data analysis will be completed by the start of the conference.Copyright © 2023

Beyond pleasure: Effects of depression, anhedonia, and COVID-19 stress on hedonic and eudaimonic reward functioning

Reward processing encompasses multiple psychological processes, including appraisals of the incentive value of a reward (reward valuation), behavioral motivation to earn it (reward wanting), and affective responses to its receipt (reward liking). Disruptions in reward processing and the vulnerability of this system to chronic stress are argued to contribute to the development of a depressive disorder and anhedonia specifically. However, research has been limited to examining responses to "hedonic" rewards as the study of "eudaimonic" reward processing presents methodological challenges. Addressing these aims, this study developed the Hedonic and Eudaimonic Incentive Delay Task (HEID) for a comprehensive assessment of reward processing across multiple reward domains, including hedonic (HE), eudaimonic (EU), and neutral-intrinsic (NT-I) rewards. The central objectives were to examine the effects of (1) depression and anhedonia-related symptoms (e.g., wellbeing, anhedonia), (2) chronic stress exposure, using the COVID-19 pandemic and case fatality rates (CFR) as objective stress measures, and (3) interventions, such as the cultivation of dispositional mindfulness and self-affirmation, on reward processing across multiple reward domains. Two samples of participants were recruited, before (N = 180) and during the COVID-19 pandemic (N = 189), completing self-report measures of depression, anhedonia, wellbeing, and mindfulness, and the HEID. Participants during COVID-19 were also randomly assigned to one of three induction conditions (Stressor Salience, Self-Affirmation, Control) to investigate stress and intervention effects. Consistent with hypotheses, (1) depression and anhedonia were associated with impaired reward processing;however, depression was more robustly associated with impairments in reward wanting, particularly the wanting of EU rewards, while reward valuation and liking were uniquely implicated in anhedonia. Chronic stress hypotheses (2) were partially supported, such that COVID-19 was associated with blunted reward wanting across reward domains (particularly NT-I), but not reward valuation and liking. Consistent with theory (3), self-affirmation helped buffer the effects of stress on reward wanting, but only at high CFR, while dispositional mindfulness was associated with greater wellbeing during COVID-19 by virtue of enhanced reward valuation and liking. This study provides new insights into reward pathways underlying stress, depression, and wellbeing/anhedonia, shedding light on disruptions to target in treatment.

Identifying Correlates of Emergent Behaviors in Agent-Based Simulation Models Using Inverse Reinforcement Learning

In large agent-based models, it is difficult to identify the correlate system-level dynamics with individual-level attributes. In this paper, we use inverse reinforcement learning to estimate compact representations of behaviors in large-scale pandemic simulations in the form of reward functions. We illustrate the capacity and performance of these representations identifying agent-level attributes that correlate with the emerging dynamics of large-scale multi-agent systems. Our experiments use BESSIE, an ABM for COVID-like epidemic processes, where agents make sequential decisions (e.g., use PPE/refrain from activities) based on observations (e.g., number of mask wearing people) collected when visiting locations to conduct their activities. The IRL-based reformulations of simulation outputs perform significantly better in classification of agent-level attributes than direct classification of decision trajectories and are thus more capable of determining agent-level attributes with definitive role in the collective behavior of the system. We anticipate that this IRL-based approach is broadly applicable to general ABMs. © 2022 IEEE.

Prototype of Covid Tracer Management Application

As the world battles against the COVID-19 pandemic, a significant part of the world is trying to ease lockdowns while rapidly identifying individuals who may have been infected. Yet, such contact tracing is commonly a relentless and slow cycle that depends on face-to-face meetings, which is also dangerous. The government has come up with a contact tracing application, but such solutions are deemed by the public as too intrusive and non-beneficial, especially when it is obvious that this pandemic will be with us for a long time. As such, by integrating a reward-based approach to contact tracing, it would increase the level of awareness and interest in actively using such solutions among the public. The aim of this application is to increase the number of users using the contact tracing application. The usage of this mobile application would be beneficial to the users, which would increase the number of users of this application. The function of a contact tracing application would be more effective with the presence of a rewards system as more people would use the application to check-in at the places they go. The system is developed using Android Studio and uses Google Firebase as the database. © 2022 IEEE.

Leadership Styles of Nurse Managers and Employees' Organizational Commitment during the COVID-19 Pandemic

Objective: The aim of this study was to determine the leadership styles of nurse managers and then determine the relationship of the respective styles with the organizational commitment of the nurse managers during the COVID-19 pandemic. Method(s): A quantitative correlational study design was employed in this investigation. Simple random sampling yielded 259 nurses who participated in this study. It was conducted between October and November 2021 at the government hospitals of the Hail Region, Kingdom of Saudi Arabia. Result(s): The nurses' perceived that their nurse managers employed an idealized influence leadership style (9.15). Age, years of experience, and ward assignment were found to have no statistically significant difference on organizational commitment;however, a significant difference was found with nationality. No significant difference was found regarding age with idealized influence, inspirational motivation, intellectual stimulation, or management by exception;however, it differed significantly with individualized consideration, contingent reward, and laissez-faire leadership. No significant differences were found with the years of experience to idealized influence, inspirational motivation, intellectual stimulation, individual consideration, or management by exception;however, it was found significantly different with the contingent reward and laissez-faire leadership. Concerning nationality, a significant difference was found with idealized influence and inspirational motivation. However, no significant difference was found between nationality and intellectual stimulation, individual consideration, contingent reward, management by exception, or laissez-faire leadership. With the ward assignment, no significant difference was found with idealized influence, inspirational motivation, intellectual stimulation, or contingent reward management by exception;however, a significant difference was found with individual consideration and laissez-faire leadership. Conclusion(s): During the pandemic, nurse managers employed idealized influence leadership styles. Age, years of experience, and ward assignment were found to be of no significant difference to organizational commitment, but they did have a significant difference to nationality. Age differed significantly with individualized consideration, contingent reward, and laissez-faire leadership. Years of experience was found to be significantly different with contingent reward and laissez-faire leadership. Concerning nationality, a significant difference was found with idealized influence and inspirational motivation. With the ward assignment, a significant difference was found with individual consideration and laissez-faire leadership.Copyright © 2023 The Author(s). Published by S. Karger AG, Basel.

The Effect of Ethics in Business on Happiness, Aggressiveness and Inconsistency of Efforts and Rewards

The present study investigates the effect of business ethics on happiness, aggression and inconsistency of effort and reward of auditors in Iran and Iraq. The statistical population of the present study includes all partners, managers and auditors working in audit institutions in Iran and partners of the audit institutions, assistant auditors, auditors, individual second rank and individual first rank, with a total of 365 questionnaires completed by Iranian respondents out of 450 questionnaires and 250 questionnaires completed by Iraqi respondents out of 350 questionnaires, a total of 615 questionnaires from the two countries in 2022. Also, the methods of variance analysis and ordinary least squares regression and Smart PLS 3 and Stata 15 software were used to analyze the data and test the hypotheses. The results from testing this research's hypotheses indicate a negative and significant relationship between business ethics and aggression, effort-reward mismatch and a positive and significant relationship between business ethics and happiness. Since the current research was conducted in the emerging financial markets of Iran and Iraq, which are highly competitive, along with having special economic conditions, and since the occupation of the ISIS terrorist group, the civil wars in Iraq, severe world economic sanctions against Iran and the global crisis of Covid-19 in Iran and Iraq have led to special conditions, the current research can bring helpful information to readers and help the development of science and knowledge in this field. © 2023 by the authors.

Effects of the COVID-19 Pandemic on Neural Responses to Reward: A Quasi-experiment.

BACKGROUND: The COVID-19 pandemic has been a prolonged period of stress due to social isolation, illness, death, and other major life disruptions. Neural reward sensitivity, essential for healthy functioning, may become reduced under major naturalistic stressors, though few studies have examined this. The present study sought to test whether neural responses to rewards were significantly blunted by the stress of the pandemic. METHODS: We compared 2 groups of young adult participants, who completed a monetary reward task while an electroencephalogram was recorded, at 2 time points, 1 to 3 years apart. Our measure of reward sensitivity was the reward positivity (RewP), a neural marker enhanced to gain relative to loss feedback. The magnitude of the RewP is sensitive to stress exposure and can prospectively predict depression. The pre-pandemic group (n = 41) completed both time points before the pandemic, while the pandemic group (n = 39) completed the baseline visit before the pandemic and the follow-up visit during its second year. RESULTS: The pandemic group reported having experienced significant stressors over the course of the pandemic. We did not observe a significant decrease in the RewP from baseline to follow-up in the pre-pandemic group. In contrast, in the pandemic group, the RewP was significantly blunted at the follow-up visit to the extent that it no longer distinguished gain from loss feedback. CONCLUSIONS: These results suggest that prolonged naturalistic stressors can result in adaptations in neural responses to rewards. Our findings also highlight a possible mechanism linking stress to the development of depression.

Brain Reward Circuits Promote Stress Resilience and Health: Implications for Reward-Based Interventions.

From the COVID-19 global pandemic to racial injustice and the continued impact of climate change on communities across the globe, the last couple of years have demonstrated the need for a greater understanding of how to protect people from the negative consequences of stress. Here, I outline a perspective on how the brain's reward system might be an important, but often understudied, protective mechanism for stress resilience and stress-related health outcomes. I describe work suggesting that reward system engagement inhibits the stress response and is associated with improved health outcomes including reduced depressive symptomatology and slowed cancer progression. I then highlight important future directions for translational research and illustrate the value of this perspective for improving behavioral interventions in clinical psychology and beyond.

Outcomes and process evaluation of a cluster-randomised participatory organisational intervention among German healthcare workers.

BACKGROUND: In the present investigation the results of the outcome and process evaluation of a participatory workplace intervention are reported. The intervention aimed to increase the workers' self-assessed physical and mental work ability. METHODS: The intervention was a two-arm, cluster-randomised trial with healthcare workers in 10 hospitals and one elderly care centre in Germany. Outcome data on workers were collected in questionnaires at baseline, and two follow-ups between 2019 and 2021. The intervention consisted of interviews and workshops, in which employees proposed measures for reducing the physical and psychosocial load and strengthening resources at work. Outcome data were analysed with linear-mixed regression models. The process evaluation was based on the thematic criteria proposed in previous literature and the collection of the type of intervention measures and their implementation status. RESULTS: The regression analysis did not provide evidence of treatment differences or reductions of psychosocial load in the intervention wards. The process evaluation suggested that the measures did not address specifically the self-assessed work ability. In addition, there was no indication that the intervention measures were causally related to the intended goals. CONCLUSIONS: The planning and implementation of organisational interventions require a careful consideration of the definition of intervention goals, the theoretical rationale of the intervention and a project-oriented action plan during the delivery phase.
