Background: Limited research has been conducted on the relationship between inflammatory markers and psychological status in medical staff fighting COVID-19.

Objective: This article examines the psychological and inflammatory conditions of medical personnel working on the front lines of the battle against COVID-19.

Methods: A total of 102 clinical staff members were included in this study. All subjects received the Symptom Checklist-90 questionnaire (SCL-90) and Posttraumatic Stress Disorder Checklist-Civilian questionnaires for assessing different mental symptoms. The levels of various inflammatory markers, including IL-1β, IL-2, IL-6, IL-8, TNF-a, and IFN-γ, along with GDNF, were evaluated.

Results: Spearman correlation analysis showed that the levels of IL-6 were positively associated with the anxiety score (Spearman's rho = .230, p = .021), obsessive-compulsive symptoms (Spearman's rho = .201, p = .042). The levels of IL-8 were negatively associated with the anxiety score (Spearman's rho = -.223, p = .028), obsessive-compulsive symptoms (Spearman's rho = -.252, p = .012), hyperarousal (Spearman's rho = -.221, p = .028). The levels of TNF-α were positively associated with the anxiety score (Spearman's rho = .201, p = .045), obsessive-compulsive symptoms (Spearman's rho = .222, p = .035).

Conclusion: Generally, our results suggested that IL-6, IL-8 and TNF-α might play a role in the development of psychological symptoms among medical staff.

Background: Dieting is a common practice around the world. People who wish to lose weight, improve their eating habits, or reach a desired level of health often diet. Rumination, a pattern of repetitive negative thoughts and emotions, is typically found when individuals diet. The current study aimed to identify physical and psychological differences between maladaptive and normative eating behaviors in a sample from Lebanon.

Methods: A cross-sectional design was adopted for the current study. It occurred between June and July 2022. Four hundred participants aged 18 and above participated. The research team used a snowball sampling method to recruit volunteers from all governorates of Lebanon.

Results: Beta values were used to compare independent variables in order to infer those that have the strongest effect on the dependent ones. Higher Body Mass Index, and belonging to cluster 3 (restriction of food intake and rumination) and cluster 1 (maladaptive eating behavior and rumination) compared to cluster 2 (normative eating behavior and thought) were significantly related to more dieting. Higher physical activity index and belonging to cluster 3 (restriction of food intake and rumination) and cluster 1 (maladaptive eating behavior and rumination) compared to cluster 2 (normative eating behavior and thought) were significantly related to higher levels of orthorexia nervosa tendencies.

Conclusions: The current research demonstrated a relationship between Body Mass Index, physical activity, rumination, and maladaptive eating patterns including restriction of food intake, dieting, and orthorexia nervosa. These results can help with identifying physical and psychological factors associated with maladaptive eating patterns, as well as guide interventions within the Lebanese population.

Background: Social support is relevant to studying well-being, quality of life, and health during aging, particularly in people over 50. Therefore, brief instruments that allow its measurement within the clinical evaluation and research processes are necessary. The ENRICH Social Support Scale (ESSI) is a brief and easy-to-use instrument that measures the perception of social support; however, its psychometric properties in people over 50 in the Chilean context have yet to be tested.

Method: This study had a non-experimental, longitudinal panel design in which a sample of 303 people over 50 years of age (M = 55.14 years, SD = 5.19; 52% women) were administered a survey incorporating sociodemographic variables, the ESSI and the Newsom Social Negativity Scale. 277 participants completed the follow-up survey (M = 56.75 years, SD = 5.15; 54% women). Confirmatory factor analysis (CFA), structural equation modeling (SEM), invariance analysis, and internal consistency tests were performed to determine the psychometric properties.

Results: The six items from the scale load in a single-factor model obtained an excellent fit to the data and reliability coefficients (α = 0.902; ω = 0.904). The SEM analysis evidenced an inverse correlation between the ESSI and Newsom's social negativity scale, demonstrating evidence of construct validity. Furthermore, in the sex invariance analyses, the scalar level was reached, implying that the items' meanings are the same for men and women. Finally, the residual level was reached in the temporal invariance analyses, which means that the scale items are consistent in time.

Conclusions: The ESSI is a reliable and valid tool to be used in the Chilean context both in the clinical setting and in research on people over 50. The evidence obtained supports its usability to appropriately measure the perception of social support, which is relevant considering that it has been associated with reports of higher quality of life and lower mortality and morbidity during aging.

Background: The recognition of facial expressions of emotions is an essential skill for social functioning, as it enables recognizing the possible intentions of others.

Main body: Cultural context is an important aspect to consider in this skill, as it tends to modulate the recognition of facial expressions.

Objective: To develop and validate a set of facial expressions of basic emotions of Brazilian individuals considering the population distribution of the country according to age group, sex, and race.

Methods: A procedure with three phases was created to generate basic emotions and photograph facial expressions. A total of 459 Brazilians were then asked to identify the emotions of these facial expressions. Content validity was investigated based on the analysis of specialists and the recognition of emotions by Brazilian individuals.

Results: The final database consists of 56 high-quality color images. A good level of agreement was found for the expressions perceived by the assessors (81.6%).

Conclusion: The percentage of correct recognition of each emotion and the characteristics of the models are presented so that future studies can choose the most adequate images to meet their specific needs.

Objectives: This article starts with increasing emotions through cognitive reappraisal and explores the impact of state gratitude emotions on interpersonal trust among college students under cognitive reappraisal.

Method: In study 1, we used a questionnaire survey and experimental design to collect data, which we processed/analyzed using SPSS 23.0. We employed, the Rotter Interpersonal Trust Scale (ITS), as adapted by Xu Huiyan, consisting of 25 items, to measure the interpersonal trust levels among college students and to explore the potentially significant differences in interpersonal trust levels among the students based on their demographic variables, including gender. We collected 347 survey questionnaires, with 143 from males and 204 from females, with a mean age of 20.93 (SD = 2.703). In study 2, we utilized a univariate inter-subject experimental design, with the independent variable being the state gratitude emotion (awakened vs. not awakened) under cognitive reappraisal, and the dependent variable was the level of interpersonal trust. Thirty participants participated in the pre-experiment, followed by 119 participants in the formal experiment to assess the impact of state gratitude emotion on interpersonal trust among college students, using motivation reappraisal strategy (t = - 4.028, p < 0.01).

Results: This study found that (1) the overall interpersonal trust of college students was moderate to low (M = 38.01, SD = 9.13); (2) no significant differences in interpersonal trust levels were found among college students based on gender, grade, and whether they had children; however, the significant differences in interpersonal trust levels were observed among college students based on their the area of residence (F = 3.675, p < 0.05), school type (F = 3.04, p < 0.05), and family type (t = - 3.034, p < 0.01); (3) cognitive reappraisal has been shown to enhance individuals' gratitude emotions in situations, thereby, raising their interpersonal trust level.

Conclusions: We conclude that cognitive reappraisal enhances individuals' positive emotions and levels of interpersonal trust in social interactions, offering a reference for promoting positive emotions and interpersonal trust levels among college students.

Background: The role of parent support for adolescents has been validated in online learning. However, less attention has been paid to undergraduates.

Main body: The research used self-reported questionnaires to investigate the mediating effects of self-regulation in parent autonomy support and academic engagement (cognitive, behavioral, and emotional dimensions) within the online environment in the context of Chinese culture.

Objective: The present study recruited 1908 undergraduates in China.

Methods: The students completed measures of parent autonomy support, self-regulation and three sub-dimensions of academic engagement.

Results: The results indicated that parent autonomy support exerted a direct and significant effect on the three sub-dimensions of academic engagement in online learning. Self-regulation partially mediated the relations between parent autonomy support and three sub-dimensions of academic engagement.

Conclusion: These findings showed parents should autonomously support students to promote their cognitive, behavioral, and emotional engagement. Moreover, the partial mediation explained how parent autonomy support affected three sub-dimensions of academic engagement. Limitations and educational implications were also discussed.

Objective: Studies have demonstrated a morphological decomposition process in the initial stages of visual word recognition based on orthographically defined morphemes and independent of semantic and lexical information. The present study sought to investigate this phenomenon in adult Brazilian Portuguese-speaking readers.

Method: Participants performed a lexical decision task preceded by primes at two Stimulus Onset Asynchrony (SOA): 33 or 250 ms. The primes had one of the following relations with the target word: morphological (porteiro [DOORKEEPER]-PORTA [DOOR]), morpho-orthographic (cordeiro [LAMB]-CORDA [ROPE]), orthographic (abril [APRIL]-ABRIU [OPENED]), semantic (abelha [BEE]-MEL [HONEY]), or no relation (pessoa [PERSON]-DADO [DICE]).

Results: Priming effects were observed for the morphological and semantic conditions at both SOAs but not for the orthographic and morpho-orthographic conditions.

Conclusion: Our results suggest that semantic representations mediate morphological priming in Brazilian Portuguese since the early stages of visual word recognition.

Background: Previous studies have shown that the Gaming Disorder Test (GDT) and Gaming Disorder Scale for Adolescents (GADIS-A) have promising validity and reliability when assessing symptoms of gaming disorder among young adults. However, validity and reliability properties of the two scales have not been established among a Vietnamese population.

Objective: The present study translated the GDT and GADIS-A into Vietnamese and examined their factor structures, measurement invariance, convergent validity, concurrent validity, and divergent validity among university students.

Methods: A total of 610 young adults (mean age = 21.09 years; 63.4% females) were recruited using convenience sampling and who completed a paper-and-pencil survey between April and June 2023. All participants completed a demographic questionnaire, GDT, GADIS-A, and six standardized scales related to gaming disorder, social media addiction, smartphone addiction, and psychological distress. Confirmatory factor analysis (CFA), internal consistency testing, and Pearson's correlations were performed.

Results: CFA showed that the GDT had a one-factor structure and the GADIS-A had a two-factor structure. The internal consistency was excellent for both scales among this population. Moreover, both GDT and GADIS-A showed convergent, concurrent, and divergent validity with other standardized scales.

Conclusion: The Vietnamese versions of the GDT and GADIS-A have good psychometrics, which may be utilized in future research regarding gaming disorder among Vietnamese populations.

Background: The stress experienced by parents in fulfilling their parental role has consequences for couple dynamics, parent-child interactions, and the mental health of parents. However, studies on the psychometric properties of the PSI-SF, particularly among Latin American parents, are scarce. Therefore, this study aims to evaluate the psychometric properties of the Spanish version of the Parenting Stress Index-Short Form (PSI-SF).

Methods: The participants were Peruvian mothers and fathers with children in early childhood and primary education, with a mean age of 34.4 years (SD = 6.8). The sample was obtained in two phases: 130 participants for the Exploratory Factor Analysis (EFA) and 791 participants for the Confirmatory Factor Analysis (CFA).

Results: The study results show a modified three-factor structure of the PSI-SF scale, with adequate fit indices (GFI = .99, AGFI = .99, SRMR = .024, CFI = .98, TLI = .98, RMSEA = .074) and loadings above 0.40. Additionally, the three factors of the scale demonstrated high reliability, with Cronbach's alpha and McDonald's omega values for Parental Distress (α = .94; ω = .95), Parent-Child Dysfunctional Interaction (α = .97; ω = .97), and Difficult Child (α = .94; ω = .94). The scale was also found to be invariant with respect to gender.

Conclusion: In conclusion, the study results suggest that the modified PSI-SF has adequate psychometric properties and is invariant for assessing parental stress in Peruvian fathers and mothers with children in early childhood and primary education.
