Visual working memory (VWM) plays a crucial role in temporarily maintaining and manipulating visual information. Retro-cue benefit (RCB) refers to the enhancement of memory performance when attention is directed toward a subset of items in VWM after their initial encoding. Our recent electroencephalogram (EEG) studies indicate that cue validity affects the mechanisms underlying RCB formation. However, previous research has not thoroughly examined whether these mechanisms differ between completely valid and highly valid cue conditions. This study investigates the consistency of RCB mechanisms under conditions of complete (100%) and high (80%) retro-cue validity. We manipulated retro-cue validity and examined cognitive processing mechanisms under different validity conditions using EEG. Specifically, we focused on the N2pc component, which reflects attentional resource allocation, and the contralateral delay activity (CDA) component, which reflects the quantity of information retained in VWM. The results, encompassing both behavioral and event-related potential (ERP) findings, show that participants in both the 100% and 80% cue validity conditions exhibit robust RCB. Notably, the degree of RCB remains consistent across these conditions, indicating that participants utilize retro-cues to enhance VWM performance to the same extent. In the 80% cue validity condition, a significant retro-cue cost (RCC) was observed, indicating that participants selectively discarded uncued items from VWM. In invalid trials, response accuracy drops to chance levels, supporting the removal hypothesis. ERP results reveal that attentional resource allocation (N2pc) and the quantity of retained information (CDA) remain uniform across cue validity conditions. The mechanism responsible for RCB formation appears to involve an all-or-nothing process of discarding uncued information rather than a flexible resource allocation strategy. This study provides insights into attention allocation and information-processing mechanisms in VWM, suggesting that conclusions drawn from tasks with completely valid retro-cues can be integrated with findings from highly valid cue tasks. These findings also illuminate the flexibility of internal attentional resource allocation during RCB formation and contribute to our understanding of attention processes in VWM.

Background: The occupational stress that contributes to the development of burnout syndrome remains one of the greatest scientific challenges. Despite years of research into burnout and its determinants, burnout continues to attract the attention of researchers, and healthcare workers (HCWs) continue to experience burnout in large numbers. Burnout has a significant impact on both the mental and physical well-being of HCWs and reduces patient-centered healthcare. This review aims to identify the factors affecting healthcare workers' burnout (FAHCWB) and their conceptual models.

Methods: The review was conducted according to Arksey and O'Malley's framework using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Searches were conducted in PubMed, Scopus, Wiley, ProQuest, Sage, Science Direct, and EBSCO using the following keywords: healthcare professionals, burnout, and internal/external factors. Empirical, qualitative, quantitative, and mixed-design research articles published in English with full-text access in peer-reviewed journals that investigated the FAHCWB were included. For an in-depth analysis of the included articles, the authors developed a data synthesis table, and thematic analysis was applied to the analysis.

Results: According to the inclusion criteria, 38 articles were selected for further data analysis. Six main themes were identified: (1) FAHCWB; (2) conceptual models of FAHCWB; (3) research tools for studying FAHCWB; (4) findings on FAHCWB in the context of different models; (5) differences between findings from different models; (6) what is known and not known about FAHCWB. The results of the review show that most researchers conduct research on factors affecting burnout (FAB) based on factors related to the work environment, with fewer studies based on individual factors, including personality factors. Most of the research is based on the model developed by Maslach et al. The Maslach Burnout Inventory (MBI) has been used in most studies.

Conclusions: Despite years of research, burnout continues to evolve rapidly, indicating that scientific research needs to be re-focused. Research should be conducted using different conceptual models and new research tools that allow the syndrome to be studied from a multidimensional perspective, including both the work environment and individual factors.

Background: Perinatal depression has become a global public health issue with a high prevalence rate. Multiple studies have confirmed the effectiveness of music intervention. Still, the current form of offline intervention ignores issues such as convenient transportation and the stigma of diseases that pregnant women are concerned about, resulting in poor adherence. This randomized controlled study will evaluate the impact of music intervention on depression, anxiety, and stress in perinatal women through the WeChat application. In addition, the usability of the WeChat application and the adherence of PND women will also be evaluated.

Methods: This randomized, open, single-center parallel controlled trial randomly divided 110 women with perinatal depression who met the inclusion criteria into a smartphone-based music intervention group and usual care group in a 1:1 ratio. The main outcome measures will consist of EPDS and WeChat application usability score. The secondary outcome measures will consist of GAD-7, CPSS, and Knowledge-Attitude-Practice questionnaire scores.

Discussion: This study will test the effectiveness of music intervention based on the WeChat application for perinatal depression and the usability of the WeChat application, to provide practical guidance for perinatal mental health care.

Deception is a common occurrence in daily life and has been shown to impair memory. This study investigated the memory-undermining effects of deception in a simulated daily life scenario, focusing on the potential moderating effect of the liars' role (i.e., actor vs. eyewitness). In a 2 × 2 between-subjects design, 128 participants were randomly assigned to one of four conditions: actors who told the truth, actors who lied, eyewitnesses who told the truth, and eyewitnesses who lied. Participants engaged in a simulated shopping task, followed by an interview where they either provided truthful or deceptive responses about the items they bought (actors) or observed (eyewitnesses). Two days later, participants completed a series of memory tests assessing item memory, source memory, destination memory, and non-believed memories. Results showed that deception impaired source memory, with a greater impairment observed for actors than eyewitnesses. Deception also led to more non-believed memories and impaired item and destination memory, regardless of the liars' role. These findings suggest that the role of liars moderates the effects of deception on memory, with self-related deception (actors) leading to greater memory impairments than other-related deception (eyewitnesses).

Background: A growing body of literature focuses on the role of benevolent childhood experiences (BCEs) in predicting adulthood well-being, in addition to adverse childhood experiences (ACEs). However, cross-cultural differences are generally ignored in this endeavor. Hence, this study aimed to explore the role of BCEs in predicting life satisfaction, resilience, and hopelessness. We also examined the potential of resilience and the role of hopelessness in mediating the relationship between BCE and life satisfaction.

Methods: A total of 850 university students from Turkey (n = 371), Portugal (n = 248), and India (n = 231), aged 17 to 58 years (M = 22.12, SD = 4.41), participated in the study. Participants completed an online protocol consisting of measures to assess BCEs, life satisfaction, resilience, and hopelessness.

Results: BCEs, hopelessness, and life satisfaction have significantly differed among the samples based on the country of residence. BCEs were positively correlated to resilience and life satisfaction and negatively to hopelessness. In the sequential mediation model, after controlling for country and sex, resilience and hopelessness sequentially mediated the relationship between BCEs and life satisfaction. BCEs were associated with life satisfaction, resilience, and hopelessness across countries and sexes. The model explains 42.8% of the variability.

Conclusion: Despite differences between countries, BCEs are important predictors of adult well-being in all three countries and should be monitored along with ACE. Further, resilience seems to have an important role in lowering the negative consequences of lower BCEs and feelings of hopelessness, pointing to the need to strengthen psychological resilience among adults.

Background: Attitudes towards medication can affect treatment outcomes and adherence through mechanisms such as placebo and nocebo effects. Questionnaires assessing both negative and positive attitudes towards medication in general, which can be used across a variety of settings and in both patient and non-patient samples, are however lacking. To fill this gap, we developed and validated the General Attitude towards Medication Questionnaire (GAMQ).

Methods: Items were selected and adapted from existing questionnaires by a group of experts. Validation of the original Dutch version took place in 4 samples: 2 recruited from the general population (n = 508; n = 279) and 2 patient samples (patients with rheumatoid arthritis, n = 121; patients with atopic dermatitis, n = 70). We evaluated the psychometric properties of the GAMQ by determining the factor structure and its stability across samples, internal consistency, and convergent validity.

Results: The GAMQ contains 6 positive and 6 negatively worded items. A factor structure was observed with three subscales, representing 'Trust in medication', 'Concerns about medication', and 'Reluctance to use medication'. The fit of the factor structure was satisfactory across samples, considering classic cut-offs, with an adequate or close to adequate fit. The total scale showed good internal consistency, good convergent validity with related scales (i.e., Beliefs about Medicines Questionnaire - General and a single medication attitude scale), and concurrent validity as reflected in associations with expectations about pain- and itch-relieving medication. It was not consistently or strongly associated with demographic or health-related characteristics.

Conclusions: The newly developed GAMQ showed satisfactory psychometric properties in a variety of populations, although limitations should be considered. The GAMQ is the first scale to assess both positive and negative attitudes towards medication in general, providing indicators of Trust, Concerns, and Reluctance regarding medication. The scale may be an informative measure for predicting treatment outcomes and adherence, as well as placebo and nocebo effects in diverse samples.

Based on the moral relativism theory, the current study proposes that individuals with indirect multicultural experiences may exhibit a "moral neutrality pattern" in complete moral judgments, that is, they may perceive others' immoral actions as less immoral and moral actions as less moral. In Study 1, using publicly available CGSS data and our large-scale survey, we found positive correlations between multicultural experiences and a tendency to express less blame for immoral behavior, and less praise for moral behavior. In Study 2, the behavioral results indicated that individuals with high multicultural experiences (HM) expressed less praise than those with low multicultural experiences (LM) for "slightly moral condition". The ERP time-domain results suggested that the HM group tended to exhibit lower LPP differential wave amplitudes than the LM group across different moral conditions (extremely immoral, slightly immoral, slightly moral, and extremely moral minus neutral moral conditions, respectively). Notably, the difference in LPP differential wave amplitude between the HM and LM groups was more pronounced for "slightly moral condition", starting from 500-700ms and continuing to 900-1100ms. Overall, this study provides preliminary behavioral and neural evidence for the moral neutrality pattern of individuals with multicultural experiences. This echoes the global concerns for ethics in today's globalization and enriches our understanding of the how individuals with indirect multicultural experiences form complete moral judgments.

Adolescents who experience poor mental health may develop chronic pain. Similarly, those with chronic pain may develop mental health symptoms. Little is known concerning how these co-occurring symptoms are associated with adolescent functioning. Our online cross-sectional quantitative study compared the specific nature of challenges to psychosocial functioning, across 4 groups: (1) adolescents with co-occurring chronic pain and mental health symptoms; (2) adolescents who only experience chronic pain symptoms; (3) adolescents who only experience mental health symptoms, and (4) adolescents who do not report either symptom. Participants completed self-report questionnaires assessing pain experiences, mental health symptoms and psychosocial functioning. After controlling for pain intensity, findings revealed significant differences, in physical, social, and family functioning across all groups. Significantly worse physical functioning was reported by adolescents with co-occurring pain and mental health symptoms and those with pain-only symptoms compared with adolescents with mental health-only symptoms and those without symptoms. Social functioning was significantly worse for adolescents who experienced co-occurring chronic pain and mental health symptoms compared with adolescents who experienced pain-only symptoms, and those with no symptoms. Significantly worse family functioning was reported by adolescents with mental health-only symptoms compared with adolescents reporting pain-only symptoms and no symptoms. Results suggest the combined impact of pain and mental health symptoms mainly influences adolescent social functioning. Future research is needed to develop standardised assessment and treatment plans to facilitate a thorough understanding of symptoms presented by adolescents who experience co-occurring pain and mental health symptoms.This study identifies that the combined impact of pain and mental health symptoms influences adolescent social functioning when compared to adolescents who experience pain-only or those without symptoms. Research is needed to develop standardised assessment and treatment plans to fully understand the symptoms presented by adolescents with co-occurring symptoms.

Background: Psychological flexibility (PF) is defined as the ability to pursue valuable life goals despite the existence of distress. The Personalized Psychological Flexibility Index (PPFI) is a new measure of psychological flexibility that can address existing deficiencies. This study aimed to translate and validate the psychometric characteristics of the Chinese version of the PPFI among medical college students.

Methods: The study was conducted in two phases. Phase 1 involved the translation and cross-cultural adaptation of the PPFI according to guidelines recommended by the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Phase 2 was a cross-sectional survey conducted on 945 medical college students in China. The psychometric performances of the scale were assessed using construct validity, divergent validity, criterion validity, incremental validity, internal consistency, and test-rest reliability.

Results: The exploratory factor analysis (EFA, n1 = 440) showed that the Chinese version of the PPFI consisted of 3 factors, with a total of 15 items. The confirmatory factor analysis (CFA, n2 = 440) showed that the three-factor structure fit well (χ²/ $\mathrm{df}$ =2.469, SRMR = 0.051, RMSEA = 0.058, GFI = 0.94, CFI = 0.985). The total Chinese PPFI score had a moderate positive association with the Comprehensive Assessment of Acceptance and Commitment Therapy (CompACT, r = 0.344) and a negative association with the Acceptance and Action Questionnaire-II (AAQ-II, r = -0.334). Furthermore, the Chinese PPFI demonstrated good internal consistency (Cronbach's α = 0.826) and test-retest reliability (ICC = 0.817, p < 0.001).

Conclusion: The 15-item Chinese version of the PPFI is a reliable and valid tool for measuring PF in Chinese medical students. However, additional studies are needed to validate its psychometric properties in more generalizable samples and other contexts.
