Special Issue Information

Dear Colleagues,

This Special Issue is set to explore current cutting-edge developments in psychology and mental health, focusing on the continuum from nation-wide and large-scale epidemiological research with robust study designs and methodological frameworks to the design and implementation of effective behavioral change interventions and clinical interventions and/or trials. It will highlight key mental health indicators and recent findings from different countries, while aspiring to depict how epidemiological findings can inform targeted interventions that address mental health issues at both the individual and population levels.

Topics include the identification of risk factors for mental illness, mapping or assessment of mental disorder burdens, the development and validation of novel scales and research tools in psychology, the role of preventive interventions, and the application of behavioral science to promote mental health and well-being across diverse populations. This issue aims to bridge research and practice, offering insights into translating data-driven evidence into impactful interventions.

Eating disorders (EDs) are complex conditions that can significantly affect health and productivity, yet their assessment in occupational settings remains underexplored. This study aimed to evaluate the psychometric properties of the Italian version of the Eating Disorder Examination Questionnaire—Short Form (EDE-QS) among 1912 workers undergoing health surveillance. Using an Item Response Theory framework, we tested dimensionality, reliability, and measurement invariance across gender, applying a graded response model to assess item discrimination and threshold parameters. Results supported an approximate unidimensional structure with excellent internal consistency (ω ≈ 0.95) and strong indices of factor score determinacy and construct replicability. Measurement invariance analyses indicated configural and metric invariance but not full scalar invariance, due to differential item functioning in a subset of items. Latent mean differences were small, with women scoring slightly higher than men, and associations with psychological, occupational, and health-related variables did not differ by gender. These findings indicate that the Italian EDE-QS shows promising structural validity as a brief measure of ED symptomatology in occupational samples in workplace contexts. However, gender-related item bias warrants cautious interpretation of specific behaviors, suggesting the need for tailored assessments to enhance diagnostic accuracy and inform preventive interventions.

Mental health concerns are increasingly prevalent among postgraduate students, who face academic, social, and career pressures. Although research on student mental health is expanding, less is known about the psychological resources that support well-being in postgraduate learners. Meaning in life has been identified as a key psychological resource that helps individuals interpret challenges and maintain coherence and well-being, and recent research highlights the contribution of self-transcendent traits such as gratitude, forgiveness, and spirituality in fostering meaning in life. However, empirical evidence on these interrelationships remains limited. This study involves 1527 Pakistani postgraduate students (M = 795; mean age = 24.89 years) recruited through multistage random sampling from ten public universities in Punjab. Participants completed the Gratitude Questionnaire, Heartland Forgiveness Scale, Spirituality Scale, Meaning in Life Questionnaire, and Mental Health Inventory (assessing psychological well-being and psychological distress). Correlation analyses showed that gratitude, forgiveness, and spirituality were positively associated with psychological well-being and negatively associated with psychological distress. Structural equation modeling (SEM) further indicated that these traits predicted mental health both directly and indirectly, with meaning in life serving as significant partial mediator. Overall, the findings highlight the central role of meaning in life in linking self-transcendent traits to mental health among postgraduate students and suggest important implications for culturally sensitive, university-based mental health initiatives.

Gambling participation among women and older adults has increased, yet research on the psychosocial determinants of gambling in these groups remains limited. This study explored sex- and age-related differences in gambling frequency, the influence of psychosocial factors such as perceived social support, psychological well-being, social connectedness, perceived social approval, and exposure to gambling within one’s network, and how these factors interact with perceptions of the social environment. A community-based sample of 634 adults (69.1% women; 28.7% aged ≥ 60; mean age = 45.7 ± 18.4) completed a survey assessing gambling behaviours and psychosocial variables. Descriptive statistics, bivariate correlations, and binary logistic regression were conducted. Regular gambling was reported by 12% of participants and was significantly more frequent among older adults and men. Higher psychosocial well-being was associated with reduced odds of regular gambling, while being female was also associated with a lower likelihood of regular gambling. Conversely, perceived social approval and an idealized view of the social environment were associated with higher odds of regular gambling, particularly among younger adults. Findings highlight the need for age- and gender-sensitive prevention strategies that strengthen meaningful social connections. Full article

The concept of positive mental health (PMH) and therefore mental well-being (MWB) have taken center stage over the last few decades. The Mental Health Continuum—Short Form (MHC-SF) is one of the most important tools for assessing MWB. This study aims to assess the psychometric properties and dimensionality of the Portuguese version of the MHC-SF by comparing three competing models. Methods: Between January and March of 2021, a survey was conducted with a convenience sample of 495 Portuguese adolescents aged 12 to 18 years, enrolled in grades 7 to 12. Descriptive statistics and bivariate statistical tests and measures associated with confirmatory factor analysis (CFA) were calculated. Results: The results of the CFA support the idea that the bifactor model fits the data better than the other competing models. The indices support unidimensionality, namely the explained common variance (ECV = 0.81), the Percentage of Uncontaminated Correlations (PUC = 0.69), and the omega hierarchical (ωH = 0.89), and point to the existence of a general MHC-SF factor. The scale showed high reliability (ω = 0.95) in the general factor. The MHC-SF has concurrent validity, correlating with other scales that assess aspects related to mental health and well-being. Conclusion: The results point to the adequacy of the bifactor model and suggest the existence of a general factor of PMH, confirming that the total score of the scale can be used. Full article
