Orthorexia Nervosa (ON) is characterized by an excessive preoccupation with healthy foods accompanied by the avoidance of self-declared unhealthy options, yet it remains unrecognized in major diagnostic guidelines. The Düsseldorf Orthorexia Scale (DOS), a 10-item self-report questionnaire using a four-point Likert scale, assesses the obsession with healthy eating. This study evaluates the reliability and validity of the TR-DOS in the Turkish context and estimates the prevalence of ON among university students. Several studies have shown that translating the DOS into various linguistic groups may exhibit different models of DOS scores. However, the psychometric properties and model fit of the DOS have not yet been investigated in Turkish-speaking populations; to address this gap, we assessed the psychometric properties of a Turkish translation of DOS (TR-DOS) in a sample of 425 university students in Türkiye. The TR-DOS revealed a 7.3% ON prevalence and a 9.0% risk of development. Weak positive associations were observed between TR-DOS total scores and BMI (r = 0.152, p = .002). Exploratory Factor Analysis confirmed the validity of TR-DOS (KMO = 0.867) with satisfactory reliability (Cronbach's alpha = 0.854). Confirmatory Factor Analysis indicated an acceptable fit for the TR-DOS model (χ2/df = 3.127, RMSEA = 0.071, SRMR = 0.046, IFI = 0.955, CFI = 0.955, GFI = 0.956, TLI = 0.932). Moderate positive correlations were found between TR-DOS and eating disorder measures (EAT-26: r = 0.428, p < .001; EDE-Q-13: r = 0.430, p < .001). The findings demonstrated that the TR-DOS is both culturally appropriate and psychometrically adequate for Turkish university students. It is a reliable and valid instrument for assessing obsessive healthy eating behaviors in this population.

Earthquakes may play a role in the development of several psychological distresses or psychopathologies. Nevertheless, protective factors such as positive emotions, psychological flexibility, and coping mechanisms may be helpful for earthquake survivors in coping. On the other hand, the role of both positive and negative emotions of earthquake survivors in psychological flexibility and coping remains elusive. Accordingly, this study aimed to examine the relationship between emotions, coping, and psychological flexibility levels of earthquake survivors considering positive and negative emotions together. A total of 330 adult participants of the cross-sectional study completed the Participant Information Form, Perceived Ability to Cope with Trauma (PACT), Psychological Flexibility (PF), and Positive-Negative Affect Schedule (PANAS) scales. Participants were aged between 20 and 68 years (Mean ± SD = 42.42 + 12.88). It was determined that as the PACT levels increased, the PF and negative emotion levels increased yet positive emotion levels decreased. As the PF levels increased, the negative emotion levels increased yet the positive emotion levels decreased (p < 0.01). According to the established model, it was concluded that the PACT was related to positive-negative emotion levels and values, being in the moment, and dissociation sub-dimensions of PF were unrelated to contextual self and acceptance (p > 0.05). In conclusion, positive-negative emotions and PF were found to have a mediating role in the coping of earthquake survivors. Mental health professionals may contribute to increasing PACT in earthquake survivors through interventions aimed at maintaining positive emotions, recognizing negative emotions, and increasing PF.

Our paper explores in a large Romanian sample (2168 adolescents) the relational costs and benefits of the number of friends at school. Using the MEDCURVE procedure to test the non-linear mediation effects, our results show that psychological safety, bullying and negative relations mediate the association between the number of friends and depression and anxiety, while social acceptance and bullying mediate the association between the number of friends and academic self-efficacy. In general, our results show that the relational benefits of friendship tend to diminish as the number of friends increase, in general over 9 friends (depending on the relational state) and parents, teachers and school counselors should help adolescents manage their number of friends in order to prevent the relational costs associated with engaging in too many (superficial) friendships.

This study aimed to investigate the associations of childhood trauma and its facets with depressive symptoms in depressed adolescents during the post COVID-19 epidemic, and explore the potential mediating role of social peer rejection in these associations. A total of 413 adolescents with depressive disorders completed the Chinese version of the Child Trauma Questionnaire Short Form, the Social Peer Rejection, and the Children's Depression Inventory. Childhood trauma (β = 0.42, p < 0.01) and social peer rejection (β = 0.18, p < 0.01) were positively related to depressive symptoms, after adjustment for demographic factors. Furthermore, social peer rejection partly mediated the relationship between childhood trauma and depressive symptoms, and the mediation effect ratio was 17.0% (p < 0.001). This study found that childhood trauma and social peer rejection are both risk factors for depressive symptoms, and social peer rejection played a mediating role in the relationship between childhood trauma and depressive symptoms.

Our study aims to describe the status of workplace violence against medical students during clinical practice, which consists of its prevalence, types, perpetrators, students' responses and influences on them, reasons for workplace violence and to determine some relevant factors of this issue through both quantitative questionnaire and qualitative interview. A descriptive cross-sectional study with mixed methods was conducted on 320 students from the second-year to the sixth-year classes at Hanoi Medical University from August 2022 to February 2023. The questionnaire was based on the WHO questionnaire survey 'Workplace violence in the health sector - country case studies research instruments - Geneva 2003'. 10 students from quantitative research who completed the questionnaire, experienced at least one type of workplace violence and consented to continue taking part in the research were chosen for in-depth interviews. The prevalence of students witnessing and/or experiencing workplace violence was 35.6% and 19.4% of the sample population had experienced at least one kind of workplace violence. Medical staff were the most common perpetrators. 86.8% of students who were exposed to workplace violence did not report the incidents for a variety of reasons. The major reasons leading to workplace violence related to patients, patients' relatives and students, among which the first-ranked ones were the patients' education level and their unsatisfied expectations. Some relevant factors to workplace violence against medical students were determined by quantitative analysis such as students' grade (OR = 3.09) and region (OR = 3.31) and were explored additionally by qualitative interview such as the student management of the instructors, students' personality, attitude and appearance as well as hospital environment. Based on the research findings, establishing prevention methods, which require action from both individuals (students, medical staff) and organizations (universities, hospitals) is recommended.

In recent years, the possibility for healthy women to consider or undertake oocyte freezing for non-medical reasons (OFNMR) allows women who want to have biological children, to enable motherhood at a later time, while protecting against age-related fertility decline. The present study explored the intended OFNMR among healthy Israeli women by looking at the interplay of age, childbearing intention and general self-efficacy - a personal resource. Two hundred fifty-one Israeli women were recruited through social networks and online forums related to women's issues in general. Participants completed self-report questionnaires addressing socio-demographic data, childbearing intention, general self-efficacy, and OFNMR intention. The results revealed that the association between women's age and OFNMR intention was insignificant. However, childbearing intention moderated the association between women's age and OFNMR intention. Specifically, the association between age and OFNMR intention was positive and significant for women with childbearing intention while for women without childbearing intention, it was negative and significant. General self-efficacy was not found to be associated with OFNMR intention. The current study shed light on the role of childbearing intention in the context of fertility decisions, especially among women who verbalize their intention for OFNMR. Routine discussion between health-care professionals and women regarding childbearing intentions is recommended, especially with women nearing age-related decline in fertility.

This systematic review evaluates studies focusing on parenting and feeding practices, children's feeding behavior, and growth stunting in Asian countries. Eight electronic databases were searched to screen studies published between Jan 2015 and May 2021. There were contradictory findings related to gender differences in growth stunting and factors that reinforce/facilitate or inhibit acquisition of optimum growth in children. Theme of parenting practices showed that time spent on childcare, traditional beliefs about child-care feeding and responsive feeding were also contributing factors. Amidst economic improvement, political, social changes, and worldwide execution of various nutritional programs, stunting continues to be relentlessly persistent and widespread in Asia. Undernutrition disturbs areas of the mind involved in reasoning, reminiscence, locomotor skills and also an adverse influence on the physical and psychological growth of children and ensuing learning capabilities. Stunted children have more anxiety and depression and lower self-esteem than non-stunted children. A public health strategy is required to: (i) properly examine stunting with time through collaborated efforts of community members and various sectors, (ii) tackle malnutrition with steps to enhance maternal nutrition during pregnancy, infant feeding practices and (iii) involvement of effective multi-sectoral partnership programs for management of stunting.

This study investigates the predictors of consistent condom use among male construction workers in South Africa who reported concurrent sexual relationships with regular partners, casual partners, and sex workers over a 3-month period. A cross-sectional survey was used to collect data from a convenience sample of 450 male workers across 18 construction work sites in the Western Cape province. Of these, 245 (54%) indicated that they had engaged in sex with all three partner types during the 3-month study period. Hierarchical multiple linear regression was then used to assess consistent condom use as a function of demographic, experiential, behavioural and cognitive characteristics. Three statistically significant predictors of consistent condom use were identified: perceived control over condom use (β = 0.252, p < 0.001), positive attitude toward condom use (β = 0.154, p < 0.05) and fear of HIV infection (β = 0.121, p < 0.05). These findings highlight the high prevalence of sexual concurrency among study participants. It also suggests that amid declining condom use, interventions which focus on enhancing an individuals' condom application skills and efficacy, that foster positive attitudes toward condom use and that strategically incorporate fear-based messaging within a multilevel framework may potentially increase condom use among individuals in concurrent sexual relationships.

Defined as the ability to adapt to adversity with a positive and stable mindset, resilience should be an important factor in coping with long-term evolving setbacks such as the COVID-19 pandemic. Although the negative mental health impacts of the pandemic are well-documented, the course of resilience during the pandemic and recovery periods remains understudied. This study examined resilience trajectories among respondents in the Canadian Personal Impacts of COVID-19 Survey (PICS) who provided data for at least two timepoints (n = 741). Resilience was measured using the Connor-Davidson Resilience Scale (CD-RISC), and linear mixed models assessed for variations in resilience over time. Sociodemographic factors were introduced as fixed-effects variables to ascertain impacts on baseline resilience scores and temporal trends. Overall, resilience levels were low throughout the course of the study. The study sample's median baseline resilience score was 26 (IQR 21-30), which is significantly lower than the 25^th percentile CD-RISC score noted in a pre-pandemic American community survey. This remained relatively unchanged until month 20 of follow-up, when point resilience scores showed a subtle (under one point), yet significant uptick from baseline. Sociodemographic analysis showed that low income was consistently associated with lower resilience (1.8-point difference, SE = 0.5, p = 0.002) throughout the observational period. Participants with a psychiatric disorder history had lower baseline resilience compared to those without any psychiatric history (3.4-point difference, SE = .05, p < 0.001). This gap decreased to 2.0 points (SE = 0.6, p < 0.001) by 24 months post baseline, suggesting that this negative effect on resilience diminished over time.

Previous studies have indicated the positive impact of physical activity on positive affect in adolescents. However, the psychological mechanism is still under-explored. The current study aims to investigate the mediating role of psychological resilience and regulatory emotional self-efficacy on the relationship between physical activity and positive affect. This cross-sectional study recruited 580 adolescents (280 females, 12 to 16 years old). All participants completed the measures of the Physical Activity Questionnaire for Adolescents (PAQ-A), the Positive and Negative Affect Scale (PANAS), the Connor-Davidson Resilience Scale, and the Regulatory Emotional Self-Efficacy Questionnaire. Results showed that the association between physical activity and positive affect was significant in adolescents. Psychological resilience played a mediating role between physical activity and positive affect. The chain mediation effect of psychological resilience and regulatory emotional self-efficacy on the relationship between physical activity and positive affect was significant. These results indicated that physical activity could positively impact adolescents' positive affect through psychological resilience and regulatory emotional self-efficacy. Our findings highlighted the importance of physical activity on positive affect on adolescents, which would benefit the mental health of this population.
