Sleep patterns and their associations with psychiatric symptoms among Chinese healthcare workers: a latent profile analysis

BackgroundHealthcare workers often encounter inadequate sleep conditions. However, limited research has examined the underlying sleep patterns among healthcare workers. This study aimed to identify sleep patterns in healthcare workers, explore predictors associated with various sleep patterns, and investigate the relationship between sleep patterns and psychiatric symptoms.MethodsThis cross-sectional study was conducted in Shenzhen, China, from April 2023 to June 2023. In total, data from 1,292 participants were included using a convenience sampling method. A latent profile analysis was conducted to identify sleep patterns based on the seven dimensions of the Pittsburgh Sleep Quality Index. Multinomial logistic regression analysis was conducted to investigate the influence of socio-demographic variables on each profile. A one-way ANOVA test was employed to examine the relationships between sleep patterns and psychiatric symptoms.ResultsThree distinct profiles were identified: good sleepers (63.9%), inefficient sleepers (30.3%), and poor sleepers (5.7%). Multinomial logistic regression analysis indicated that gender and marital status were predictors of various sleep patterns. The ANOVA revealed significant differences in psychiatric symptoms scores among the three sleep patterns; poor sleepers exhibited the highest levels of mental distress.ConclusionThis study identified three distinct sleep patterns in healthcare workers and their significant associations with psychiatric symptoms. These findings contribute to the development of targeted intervention strategies aimed at improving sleep and reducing psychiatric symptoms among healthcare workers.

The impact of the COVID-19 pandemic on nostalgic social media use

IntroductionDespite popular speculation that nostalgic social media use skyrocketed during the COVID-19 pandemic, this has yet to be formally investigated in the scientific literature.MethodsInterrupted time series analysis (ITSA) using a segmented regression model was performed to examine the changes in the weekly volume of searches for nostalgic songs on Douyin (the Chinese version of TikTok), as a proxy for nostalgic social media use, before and after the lockdown of Wuhan (signaled the start of the pandemic on a national scale in China).ResultsAcross the study period (January 1, 2019–February 28, 2021), an immediate and significant increase in nostalgic social media use was observed when the pandemic initially started (95% CI = [47314.30, 154969.60], p < 0.001) compared with the pre-pandemic baseline.DiscussionThis study provides empirical evidence for the impact of the pandemic on nostalgic social media use. It also advances our understanding of the increased usage of social media during the pandemic. Additionally, as nostalgia has drawn increasing attention from media researchers, this study offers methodological insights into the quantification of nostalgia.

An international estimate of the prevalence of differing visual imagery abilities

The aim of this research was to establish prevalence estimates for aphantasia, hypophantasia, typical imagery ability, and hyperphantasia in a large multi-national cohort. In Study 1, the Vividness of Visual Imagery Questionnaire was completed by 3,049 participants. Results indicated prevalence estimates of 1.2% for aphantasia, 3% for hypophantasia, 89.9% for typical imagery ability, and 5.9% for hyperphantasia. In Study 2, to replicate these findings in a larger sample, the Study 1 data were combined with openly available data from previous prevalence studies to create a total sample of 9,063 participants. Re-analysis of this data confirmed prevalence estimates of 0.9% for aphantasia, 3.3% for hypophantasia, 89.7% for typical imagery ability, and 6.1% for hyperphantasia. These robust and up-to-date estimates provide enhanced clarity to researchers regarding the prevalence of differing visual imagery abilities and provide a platform for future studies exploring the role of visual imagery in various cognitive and behavioral tasks.

Activity-based mindfulness: large-scale assessment of an online program on perceived stress and mindfulness

Background and objectiveMindfulness has emerged as key construct in mental health over past decades. While current mindfulness-based interventions (MBIs) are usually rooted in Asian contemplative traditions, mindfulness practices can equally be found in other knowledge systems, including integrative medicine systems such as anthroposophic medicine (AM). The Activity-Based Stress Release (ABSR) program incorporates the latter as part of an 8-week-long online intervention combining mindfulness exercises, behavioral self-observation, and mindful movement practices derived from this integrative medicine frame. The program could offer additional means for cultivating mindfulness, thereby addressing the necessity for diverse approaches in conjunction with individual differences, diverse clinical demands, or restricted capacities to perform certain mindfulness practices. Using an observational repeated-measures design, the current study aimed to assess a large-scale online implementation of this program in terms of its feasibility, assessing perceived stress and mindfulness.MethodIndividuals who enrolled in any of the 37 ABSR program iterations carried out during 2023 and agreed to participate in the study completed online surveys including validated stress and mindfulness scales at the beginning, middle, end, and follow up of the intervention. Linear-mixed models were used for data analysis.ResultsA total of 830 individuals took part in the study, of which 53.5% filled in at least 2 surveys. In line with our expectation, mindfulness scores increased significantly over the course of the intervention, while stress scores decreased significantly in this timeframe. We further found differential effects of self-practice frequency and duration on the outcomes.ConclusionThis study provides a first indication of stress reduction in conjunction with the online implementation of this novel MBI. The work further suggests that this AM-based intervention indeed targets mindfulness, as do other MBIs, and that it is adaptable to an online format. However, given the observational single-arm design, controlled studies will be necessary to confirm these results. Nonetheless, the study adds a novel contribution to existent MBIs, which is significant in view of the need for diverse approaches to meet the heterogeneity of individual predispositions and clinical requirements. It remains to established by forthcoming research for which groups of individuals or clinical features this approach could be especially beneficial or less suitable.

The role of socio-emotional attributes in enhancing human-AI collaboration

This article delves into the dynamics of human interaction with artificial intelligence (AI), emphasizing the optimization of these interactions to enhance human productivity. Employing a Grounded Theory Literature Review (GTLR) methodology, the study systematically identifies and analyzes themes from literature published between 2018 and 2023. Data were collected primarily from the Scopus database, with the Web of Science used to corroborate findings and include additional sources identified through a snowball effect. At the heart of this exploration is the pivotal role of socio-emotional attributes such as trust, empathy, rapport, user engagement, and anthropomorphization—elements crucial for the successful integration of AI into human activities. By conducting a comprehensive review of existing literature and incorporating case studies, this study illuminates how AI systems can be designed and employed to foster deeper trust and empathetic understanding between humans and machines. The analysis reveals that when AI systems are attuned to human emotional and cognitive needs, there is a marked improvement in collaborative efficiency and productivity. Furthermore, the paper discusses the ethical implications and potential societal impacts of fostering such human-AI relationships. It argues for a paradigm shift in AI development—from focusing predominantly on technical proficiency to embracing a more holistic approach that values the socio-emotional aspects of human-AI interaction. This shift could pave the way for more meaningful and productive collaborations between humans and AI, ultimately leading to advancements that are both technologically innovative and human-centric.

Influence of slow and rapid weight loss periods on physiological performance, mood state and sleep quality in male freestyle wrestlers: a study from Sichuan Province, China

ObjectiveThis study aims to investigate the changes in physiological performance, mental state and sleep quality during the weight reduction phase prior to competition in male freestyle wrestlers.MethodsThis study included 16 male freestyle wrestlers from Sichuan Province, China. Participants were evaluated at three time points: the first day of slow weight reduction (T1, March 26), the first day of rapid weight reduction (T2, April 26) and the day before the competition (T3, May 3), and measurements were taken for physiological performance, mood state and sleep quality.ResultsThe most relevant findings indicated the following: Morning heart rate, creatine kinase and fatigue scores increased by 12.6, 64.6, and 19.0%, respectively, from T1 to T2 (p < 0.05), and decreased by 14.1, 36.6, and 16.8%, respectively, from T2 to T3 (p < 0.05). Hemoglobin and testosterone levels decreased by 3.0 and 16.8%, respectively, from T1 to T3 (p < 0.05), and by 2.9 and 18.2%, respectively, from T2 to T3 (p < 0.05); The secondary findings revealed the following: The total mood disturbance scores decreased by 3.8% from T2 to T3 (p = 0.072), positive mood scores decreased by 9.0% from T1 to T2 (p = 0.090), the Pittsburgh Sleep Quality Index total scores increased by 14.4% from T1 to T2 (p = 0.323) and total work output and average power output decreased by 7.3 and 7.8%, respectively, from T1 to T3 (p = 0.067, p = 0.052); Regression analyses predicted negative mood (Y1 = 62.306–0.018 × maximum power output) and sleep quality (Y2 = 2.527 + 0.278 × Immunoglobulin G) during the weight reduction period.ConclusionThe combined slow and rapid weight reduction approach effectively minimized body fat in athletes with limited effect on their physiological performance and sleep quality. However, the effects were adverse on certain health variables and anaerobic power in Chinese male freestyle wrestlers. The identified correlations between negative mood and maximum power, and between sleep quality and immunoglobulin G, shed new light on factors influencing athletes’ well-being during weight reduction, and underscored the need for careful monitoring of physiological variables in future weight management strategies.

Applying a new theoretical and methodological approach for behavior-change campaign planning: identifying the critical determinants for reducing littering and evaluating the resulting large-scale campaign

IntroductionThis paper presents a theoretical concept and methodological approach for identifying critical determinants for behavior change interventions. The approach is based on established theories and constructs but represents them in an intervention- instead of questionnaire-oriented form. Six discriminant and targetable dimensions of behavior determinants are proposed: Consideration, feasibility, instrumental evaluation, norms and goals, affective evaluation, and needs and tension states.MethodsFor estimating the importance of these dimensions for a specific behavior to be changed in a specific situation and population, a quasi-experimental approach is proposed, in which interventions are designed to have effects on one of these dimensions but none on the other dimensions. By measuring changes of the target behavior or its consequences, the impact of each dimension on changing the behavior can be estimated in-situ without questionnaires. The approach was applied to develop a campaign for reducing picnic littering in an urban park in Zurich (Switzerland). In 2019, posters targeting four dimensions were set up during three waves in up to four zones with two control zones without posters. Before, between, and after the intervention waves, for at least 2 weeks, no interventions were in place. The volume of litter was measured on 119 days at 55 points.ResultsIn some cases, the amount of litter was too small for effects to be detected, but where enough littering occurred, posters providing information, inducing positive emotions, or activating reciprocity norms—as well as providing the option of separating fractions of waste for recycling as a structural measure—reduced litter significantly. Interventions targeting the tension state of disgust had no effect. Posters targeting descriptive and injunctive norms increased the amount of litter.DiscussionBased on the results of the preparative study, a large-scale campaign was designed, implemented, and evaluated in 2022, which led to promising effects.

A multimodal physiological-psychological data-driven study on differentiation in miners’ job burnout and risk preferences

BackgroundExisting research indicates that the personality traits of miners influence their emotional regulation strategies, and these strategies in turn affect their performance in work fatigue. However, whether there is an intermediary or moderating role among these factors remains unclear. Additionally, while some studies suggest an increased likelihood of unsafe behavior among miners following fatigue, physiological data concerning their cognition remains incomplete and requires further exploration. This study aims to explore the mediating and moderating effects of emotional regulation strategies among miners regarding their personality traits and work fatigue, and to expand understanding of the cognitive and physiological data related to miners’ risk decision-making following fatigue.MethodFifty adult miners (Mage = 25, aged 18–40, 100% male) were selected as participants. Emotional regulation tendency, significant levels of personality traits based on the Big Five Personality Traits questionnaire, and the three-dimensional levels of work fatigue were measured using emotional regulation strategy scale, Big Five Personality Traits questionnaire, and work fatigue scale, respectively. The eye–brain consistency hypothesis posits that eye movement trajectories and fixation points reflect the brain’s cognitive processes and focus. Therefore, combining eye-tracking experiments, miners’ preferences in risk decision-making were further measured.ResultsExpressive suppression strategies mediated between conscientiousness and depersonalization; expressive suppression strategies moderated between agreeableness and emotional exhaustion. In eye-tracking physiological experiments, significant differences were found in eye movement data among miners with varying levels of emotional exhaustion.ConclusionPreferences in emotional regulation strategies play mediating and moderating roles between miners’ Big Five Personality Traits and work fatigue. The levels and dimensions of work fatigue are influenced not only by personality traits but also by individual tendencies in emotional regulation strategies, which significantly affect performance in risk decision-making. The findings of this study can further enrich theories related to work fatigue among miners and provide insights for personalized safety management in mining.

A study of a PERMA-based positive psychological intervention programme in subthreshold depressed patients with newly diagnosed breast cancer: formulation and application

BackgroundDepression seriously affects the quality of life of breast cancer patients and even hinders treatment and recovery after diagnosis. Subthreshold depression should be worthy of attention, and the risk of subthreshold depression developing into depression increases if timely intervention is not available. However, there is limited research on interventions for subthreshold depression, especially for newly diagnosed breast cancer patients.ObjectiveExploring the efficacy of a PERMA-based positive psychological intervention programme in newly diagnosed breast cancer patients with subthreshold depression.MethodsUsing PERMA as a framework, we constructed the intervention programme through a literature review and expert discussion approach, and revised the programme using the Delphi method. Then we selected 84 newly diagnosed breast cancer patients for a randomised controlled trial. The control group received conventional care (primary care, specialist care, psychological care, etc.), and the observation group received a PERMA-based positive psychological intervention programme. Patient data were collected before and after the intervention, and the dataset consisted of patient responses to general information, the Depression Screening Scale (CES-D), the Hamilton Depression Inventory (HAMD-17), and the Questionnaire on Psychosocial Adjustment in Breast Cancer Patients.ResultsA total of 79 patients completed the study (38 patients in the observation group and 41 patients in the control group), and before the intervention, there were no statistical differences in the comparison of general information, subthreshold depression scores, and psychosocial adaptation scores between the two groups (p > 0.05). After the intervention, the subthreshold depression (CES-D and HAMD-17 scores) scores of the observation group were lower than those of the control group (p < 0.01), and the psychosocial adaptation scores were significantly higher than those of the control group (p < 0.01).ConclusionA positive psychological intervention programme using PERMA as a framework was more effective in reducing subthreshold depression levels and promoting levels of psychosocial adjustment in newly diagnosed breast cancer patients.Implications for practiceInterventions for subthreshold depression are not limited to the traditional aftercare model, but rather from a positive psychology perspective. Especially for patients newly diagnosed with breast cancer, this is a new endeavour that has important implications for them. Because, instead of focusing on their negative emotions, we help them gradually adapt to their new identity and treatment process from a positive aspect during their most difficult period, thus reducing their subthreshold depression level and preventing it from developing into a more severe depression.

Gaze behavior in response to affect during natural social interactions

Attention in social interactions is directed by social cues such as the face or eye region of an interaction partner. Several factors that influence these attentional biases have been identified in the past. However, most findings are based on paradigms with static stimuli and no interaction potential. Therefore, the current study investigated the influence of one of these factors, namely facial affect in natural social interactions using an evaluated eye-tracking setup. In a sample of 35 female participants, we examined how individuals' gaze behavior responds to changes in the facial affect of an interaction partner trained in affect modulation. Our goal was to analyze the effects on attention to facial features and to investigate their temporal dynamics in a natural social interaction. The study results, obtained from both aggregated and dynamic analyses, indicate that facial affect has only subtle influences on gaze behavior during social interactions. In a sample with high measurement precision, these findings highlight the difficulties of capturing the subtleties of social attention in more naturalistic settings. The methodology used in this study serves as a foundation for future research on social attention differences in more ecologically valid scenarios.

Weight-control compensatory behaviors patterns and correlates: a scoping review

ObjectiveWeight-control compensatory behaviors appear to be a commonly utilized strategy for health management. Individuals engaging in such behaviors believe that the negative consequences from unhealthy behaviors will be neutralized by the positive consequences of healthy behaviors. Existing research has not reached a consensus on whether such behaviors are beneficial to health. This review aims to (1) summarize the patterns of weight-control compensatory health behaviors in different populations, (2) highlight correlates, predictors, and consequences of compensatory health behaviors, and (3) identify gaps for future research.MethodThis review identified existing literature using online databases, CINAHL and PubMed. Primary research articles published after 2000 with non-clinical participants of 12 years or older who engaged in compensatory behaviors for weight control purposes were selected. Descriptive statistics were extracted from 35 studies.ResultsDifferent patterns for weight-control compensatory behaviors emerged between the female and male sexes. Meanwhile, no clear association of such behaviors was found across weight status. Studies reviewed also highlighted three main areas of compensatory behaviors for weight management, namely dietary behaviors, physical activity, and alcohol consumption. Weight-control compensatory behaviors had significant negative correlations with mental health indicators, such as psychosocial functioning, emotional differentiation ability, and body esteem.ConclusionWeight-control compensatory behaviors may be a widely used weight management strategy and can be presented in diverse ways. Although believed to be promoting health, such behaviors appear to be associated with poor psychological well-being. This emerging topic warrants more in-depth investigation to establish the direction of causation. Future research may investigate the relationship between weight-control compensatory behaviors and various aspects of health over longer time periods, examine the engagement of multiple weight-control compensatory behaviors, and focus on high-risk populations.

From the lab to the field and back: the effects of need satisfaction on reconciliation among Germans and Israelis

IntroductionPrevious lab experiments supported the needs-based model of reconciliation, which posits that discussing historical transgressions enhances the need for acceptance in groups perceived as perpetrators and empowerment in groups perceived as victims. Addressing these needs (e.g., through accepting or empowering messages from outgroup members) increases willingness to reconcile. This study tests this model in a real-world settings.MethodsStudy 1 examined 143 German and Israeli Jewish participants from youth exchange programs, measuring their feelings of acceptance/empowerment, program satisfaction, outgroup attitudes, and keeping in touch with outgroup members. Study 2 examined 293 Israeli Jews, manipulating the salience of the conflict between Israelis and Palestinians in a pre-registered laboratory experiment and measuring responses to accepting versus empowering messages from Germans.ResultsAs expected, Study 1 (N =143) found Germans’ feelings of acceptance were linked to program satisfaction, positive outgroup attitudes, and keeping in touch. For Israeli Jews, feelings of empowerment were linked to satisfaction and positive attitudes, but keeping in touch was unexpectedly linked to acceptance. This unexpected effect maybe because keeping in touch is done mainly through social networks that focus on the conflict between Israelis and Palestinians, often with a focus on Israel’s transgressions against Palestinians. Consistent with this explanation, Study 2 (N=293, pre-registered) showed that Israeli Jews viewed accepting messages from Germans as more conciliatory when presented with transgressions against Palestinians, and empowering messages as more effective when presented with reminders of historical victimization by Nazis.DiscussionThe findings from Study 1 partially support the needs-based model of reconciliation and additionally suggest that reconciliation needs vary with context. Implications for people-to-people peace-building interventions are discussed.

“I feel so small and big at the same time”—exploring body experience and binge eating disorder following inpatient treatment: a qualitative study

BackgroundLimited research into binge eating disorder (BED), a low treatment rate, and a lack of treatment rights, reflects a marginalized disorder in society and a treatment context.AimThe aim of this study was to gain a deeper understanding of the psychopathology of BED, by exploring the patients’ meanings related to the disorder and the role of the body in the treatment of BED.MethodQualitative methodology using a reflexive thematic analysis. The data material is based on semi-structured in-depth interviews with six cis-gendered women who had previously completed an inpatient treatment program for BED at a department for EDs and met the criteria for 307.51 Binge Eating Disorder in DSM-5.ResultsThe qualitative analysis rendered two meta-themes comprising six themes and 12 subthemes. The initial meta-theme was “Relational challenges and feelings could not be talked about at home.” The secondary meta-theme was “Body contempt disturbs the experience of self and others” and the third was “Their body has not been a theme in previous treatment.” This categorization depicts a narrative of the disorder in terms of development, current condition, and experiences with prior treatment.DiscussionThe findings indicate that shame and disgust are central to playing pivotal roles in the embodiment of BED, highlighting the significance of addressing one’s relationship with their body for achieving recovery and preventing an experienced repetition of the perceived rejection as a child.

Do emotional demands and exhaustion affect work engagement? The mediating role of mindfulness

AimThe current paper seeks to elucidate the interrelationships among emotional demands (ED), emotional exhaustion (EE), mindfulness, and work engagement (WE), with an explanation of the mediating role of mindfulness within indicated relationships.BackgroundNurses working in a stress-related environment face some emotional challenges. New methods such as mindfulness should be learned; therefore, positive outcomes occur along with new developments.MethodResponses were received from nurses through a self-report questionnaire using the convenience sample technique. Four hundred and twenty-nine nurses from health institutions in Istanbul participated in the study. The PLS-SEM technique was used to test the research model.ResultsED and mindfulness, EE and mindfulness, and mindfulness and WE relationships were found. While mindfulness was a mediator between EE and WE, it was not a mediator between ED and WE.ConclusionIt has been revealed that nurses cope with job-related challenges by being present at the moment with high awareness. Furthermore, mindful nurses also foster positive outcomes.Implications for nursing managementPrecautions should be taken because of the nursing shortage. It is better to provide mindfulness training to nursing students in schools before their professional lives. Implementing and using technologies might be helpful for nurses.

Intellectual humility and the learning sciences: can self-reports and behavioral measures coexist to understand civic engagement?

Recent political events across the globe have illustrated a resurgence in people’s intolerance to ideas different from their own. We mobilize the idea of intellectual humility to assess how extant psychological theories account for individual differences in people’s tolerance for conflicting ideas. Then, we introduce concepts from the Learning Sciences to determine how alternative methodologies could augment research on intellectual humility and civic engagement. Last, we summarize these analyses by pointing to their relations with three intersecting challenges and solutions regarding studying IH in multiple contexts and with new multiple data sources.

More cognitive gains from social activity in the oldest-old: evidence from a 10-year longitudinal study

BackgroundPrevious research has indicated that engagement in social activities has proven advantageous for diminishing the likelihood of cognitive decline. However, no study has examined whether such cognitive benefits were to a similar extent for the young-old, the old–old, and the oldest-old groups. The purpose of this research was to determine whether aging would have an impact on the changes in cognitive function that would occur in older adults with varying degrees of social involvement.MethodsThe sample for this study comprised 4,481 older adults who participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) during the waves spanning from 2008 to 2018. At baseline, participants were classified into the young-old (60–69 years; Mage = 66.66; SD = 1.87), the old–old (70–79 years; Mage = 74.21; SD = 2.82), and the oldest-old (80 years or older; Mage = 86.46; SD = 5.71) groups.ResultsThe level of cognitive function decreased as participants aged. Importantly, compared to those lacking social activities, individuals who were got involved in social engagement at baseline had slower rates of cognitive decline over time. Furthermore, compared with the young-old group and the old–old group, the impact of social activity engagement on slowing cognitive decline was more salient for the oldest-old group.ConclusionActive engagement in social activities can slow age-related cognitive decline, particularly for the oldest-old group. To preserve cognitive function with aging, attention and resources should be allocated to encourage social activity engagement.

Variations in online self-regulated learning abilities among Chinese K-12 teachers across different regions and levels

IntroductionOnline self-regulated learning (OSRL) is crucial for online learners’ success and lifelong learning. This study investigated the OSRL characteristics of K-12 teachers in China, who embody the dual roles of learners and educators. It also analyzed the differences in OSRL abilities across different genders, education stages, and school locations, and examined the correlation between education qualifications, years of service, and OSRL abilities.MethodsA self-report measure was used to assess K-12 teachers’ OSRL, with data collected from 1,443 K-12 teachers (394 males and 1,049 females) in northeastern China. Descriptive statistical analysis was utilized to explore the characteristics of their OSRL. Independent t-tests and ANOVA were employed to investigate differences in OSRL among different genders, regions, and educational stages. Correlation analysis was conducted to examine the relationships between education qualifications, years of service, and OSRL among K-12 teachers.ResultsThe data analysis revealed that K-12 teachers scored the lowest in Online Learning Self-Efficacy (OLSE), followed by Online Learning Management Strategies (OLMS), and then Online Learning Resource Management (OLRM). Notably, urban K-12 teachers exhibited higher OLSE abilities than their rural counterparts, while high school teachers scored higher in OLSE and OLMS compared to primary school teachers. Furthermore, a positive correlation was observed between education qualifications and K-12 teachers’ OLSE, whereas a negative correlation was identified between years of service and K-12 teachers’ OLSE.ConclusionThe findings reveal an uneven development across various dimensions of online self-regulated learning among K-12 teachers, necessitating support for the advancement of OLSE, OLMS, and OLRM. Particular attention should be given to the OLSE of teachers with longer teaching years and rural teachers. Encouraging K-12 teachers with lower education qualifications to pursue further education is also recommended. This study provides evidence and a novel perspective for teacher educators to develop online professional development programs, which is significant for optimizing online learning experiences and enhancing educational outcomes.
