Abstract
Chronic pain is widely recognized not only for its physical discomfort but also for its detrimental effects on core cognitive functions such as attention, memory, and executive control. The perception and interpretation of pain depend heavily on cognitive processes, and recent studies suggest that pain and cognition share common neural mechanisms, indicating a bidirectional and integrated neurobiological interaction. This review consolidates neuroimaging findings demonstrating that chronic pain induces structural and functional alterations in key brain regions involved in cognitive regulation and resource allocation. This review further highlights the importance of early identification and therapeutic intervention for cognitive decline in individuals with chronic pain. In addition, it emphasizes the potential of cognitive neuroscience-based approaches informed by advanced neuroimaging techniques, including high-resolution imaging, multimodal integration imaging, and machine learning-driven predictive models. These insights underscore the critical role of neuroimaging in chronic pain management and in developing personalized diagnostic tools and cognitive intervention strategies.

Abstract
This study investigated the impact of misspecifying the source of differential item functioning on detection accuracy using a factor mixture model that incorporates covariates, when both observed DIF (ODIF), caused by known group membership, and latent DIF (LDIF), caused by latent class membership, coexist within a single test. DIF type, magnitude, and sample size were systematically varied to evaluate model performance in terms of class enumeration accuracy, detection power, Type I error rate, and parameter bias. The results showed that the model including both LDIF and ODIF (L&ODIF model) yielded the highest accuracy in estimating the number of latent classes, while the ODIF-only model showed very low estimation accuracy. The detection power for LDIF was highest in the L&ODIF model, whereas ODIF detection was most accurate in the ODIF-only model. The L&ODIF model demonstrated lower Type I error rates in most conditions, and parameter bias remained within or slightly above acceptable levels. These findings suggest that when both types of DIF are present, applying a factor mixture model capable of detecting LDIF and ODIF simultaneously can improve detection accuracy.

Abstract
This study reviews how the concept of shame has been defined differently across academic fields and examines its multidimensional structure. By analyzing psychoanalytic, emotion-theoretic, phenomenological, cognitive-attributional, and functionalist approaches, the review identifies four recurrent issues in shame research: disciplinary differences in interpretation, ambiguity in distinguishing shame from related self-conscious emotions, diversity in measurement tools and the resulting limitations in cross-study comparability, and cultural variability in conceptual construction and flexibility in interpretation. The study then examines how the appraisal-feeling-motivation model proposed by Gausel and Leach (2011) provides theoretical responses to these issues. The model distinguishes self-defect appraisal from other-condemnation appraisal, separates shame from inferiority and rejection, and demonstrates how specific appraisal-feeling combinations are linked to either improvement motivation or defensive motivation. Through this analysis, the review conceptualizes shame not as a single emotion but as a sequence of multidimensional appraisal-feeling-motivation processes that collectively constitute the experience of shame. Overall, the study reorganizes the conceptual landscape of shame and offers an integrative foundation for future theoretical and empirical research.

Abstract
The purpose of this study was to examine changes in PGD symptoms over time and to identify internal and external factors influencing PGD at each time point among 441 adults who experienced bereavement. To achieve this, longitudinal data were collected at two time points with a 15-month interval. The results were as follows: First, PGD symptoms tended to intensify over time rather than naturally subside. Second, cross-sectional hierarchical regression analysis revealed that being female, living alone, being older at the time of bereavement, not relatives but having a more intimate relationship with the deceased compared to a third-degree relative, experiencing an unexpected loss, reporting lower levels of meaning integration, and higher levels of social meaning-making (social validation) were associated with higher PGD symptoms. Third, longitudinal hierarchical regression analysis showed that being female, having lower levels of meaning integration, and having lower levels of social meaning-making (social invalidation- recognition for others) were significantly associated with higher PGD symptoms over time. These findings suggest that PGD is not merely an emotional reaction but a condition influenced by multiple contextual and interpersonal factors. In particular, it may result from the failure of cognitive and emotional integration, such as difficulty in meaning-making after loss and perceiving supportive social responses. These findings showed that PGD is influenced by several contexts, environments, and can be derived from failure of cognitive and emotional integration, such as failure to make meaningful bereavement, and recognition of social reaction over simple emotional reaction. This study provides valuable insights for developing preventive interventions and personalized psychological support for individuals experiencing bereavement.

Abstract
his study examined the pathway through which Belief about Emotional Expression influence somatization via Ambivalence over Emotional Expressiveness, and tested the moderating role of attentional control in this process. A survey was conducted with 296 Korean adults(149 men; mean age = 40.46 years), the data were analyzed using a moderated mediation model. The results indicated that ambivalence over emotional expressiveness partially mediated the relationship between belief about emotional expression and somatization. Specifically, stronger negative belief about emotional expression were associated with greater conflict between the desire to express emotions and the tendency to inhibit emotional expression, which in turn was related to higher levels of somatic symptoms. In addition, attentional control moderated not only the effect of belief about emotional expression on ambivalence over emotional expressiveness but also the overall pathway leading to somatization. When attentional control was high, positive changes in belief about emotional expression were more strongly associated with reduced ambivalence over emotional expressiveness and lower levels of somatization. These findings suggest that attentional control functions as a key moderating variable that amplifies the effects of changes in belief about emotional expression and provide empirical support for contemporary psychotherapeutic approaches that incorporate attentional control training.

Abstract
Chronic diseases are leading causes that undermine health and quality of life in older adults, with hypertension and diabetes being the most prevalent and high-risk conditions. As the aging population grows, the need for effective prevention and management strategies for chronic diseases in preparation for a super-aged society has become increasingly important. This study aimed to examine the effectiveness of a manualized behavior-modification program when delivered by paraprofessionals for the management of chronic diseases in older adults. Eleven staff members from public health centers and sub-centers in Gangwon Province were randomly assigned to either the intervention or control group, and the 130 older adults (≥ 60 years) with chronic diseases under their care were allocated to the same groups. The intervention was implemented over a six-month period. Results indicated that, compared to the control group, the intervention group showed significant improvements in disease-management knowledge efficacy and self-management efficacy, as well as a reduction in body mass index (BMI). In contrast, systolic blood pressure and self-management behavior varied depending on the analytic approach, and no significant differences were observed in disease-management knowledge scores, systolic/diastolic blood pressure, or other health behaviors. In addition, treatment fidelity assessment demonstrated that all core elements achieved compliance rates above 80%, confirming that paraprofessionals delivered the program consistently according to the manual. These findings suggest that behavior-modification interventions delivered by paraprofessionals may be effective in enhancing health behaviors and improving certain physical indicators among older adults with chronic diseases.

Abstract
Maximum likelihood (ML), which is commonly used to estimate structural equation models, is based on the assumption of normality in the data. However, violations of the normality assumption are frequently reported in psychology and the social sciences, which can lead to biased estimation results and undermine the validity of statistical inferences. Although alternative methods that can provide reliable results under non-normal conditions have been explored, the performance of these methods has shown inconsistent patterns across studies, making it difficult to establish clear criteria for selecting appropriate methods. This study aims to address the problems posed by violations of the normality assumption and to explore alternative methods for dealing effectively with such violations. By integrating studies from the last 30 years of research, the study attempts to provide practical guidelines for researchers confronted with non-normality in their data. It first discusses the importance of the normality assumption in ML and examines the impact of its violation on estimation results. It then presents several alternative methods that are applicable under non-normal conditions and analyses the principles by which these methods deal with non-normality. Furthermore, previously published studies are systematically reviewed and categorized according to specific conditions, with the results visualized through tables and figures to compare the performance of different methods. Finally, the study integrates these discussions to propose guidelines for researchers and highlight their implications and limitations.

Abstract
Many studies have verified a significant association between lay beliefs about happiness and well-being. However, they have been limited in clarifying the temporal precedence between these two variables because most prior studies have relied on cross-sectional data. To address this limitation, we conducted an autoregressive cross-lagged analysis using longitudinal data collected from 209 Korean adults across three time points over a five-year period (2017-2022). The results showed that lay beliefs about happiness at a prior time point were not associated with well-being at a later time point, whereas well-being at a prior time point was associated with lay beliefs about happiness at a later time point. More specifically, subjective well-being at the prior time point was positively associated with hedonic happiness beliefs at a later time point. This study contributes by identifying the temporal precedence between lay beliefs about happiness and well-being, suggesting that the relationship between lay beliefs about happiness and well-being may be bidirectional rather than unidirectional.

Abstract
This study attempted to investigate the influences of negative affect, negative urgency and eating expectancy on binge eating behavior. The 696 male and female participants completed Positive and negative Affect Scale, UPPS-P scale, Eating Expectancy scale and Bulimia Test-Revised scale. The result s were as follows. first, negative affect, negative urgency, and eating expectancy correlate with binge eating behavior. Second, negative affect, negative urgency, and eating expectancy significantly predicts binge eating behavior. Third, negative affect influence binge eating behavior by interacting with negative urgency and eating expectancy respectively. That is, negative affect, negative urgency, and eating expectancy showed two-way interaction in predicting binge eating behavior. Fourth, negative affect, negative urgency, eating expectancy showed three-way interaction in predicting binge eating behavior. Specifically, the higher the levels of eating expectancy were, the much more interacting effect of negative urgency on the relationship between negative affect and binge eating behavior has increased. Finally, the findings were discussed and limitations of this study and suggestions for future study were addressed.
