Apolipoprotein E (APOE) ε4 is a recognized genetic risk factor for dementia and has been explored in connection with depression. However, the interplay between APOE ε4, depressive symptoms, and cognitive function remains unclear. Given the rising prevalence of dementia and late-life depression among older adults, this study focused on individuals aged 65 and older. We classified 514 neurology outpatients into two groups based on their APOE ε4 carrier status and categorized cognitive function into three levels—subjective cognitive decline, mild cognitive impairment, and dementia—following DSM-5 diagnostic criteria. Cognitive function was assessed using the Seoul Neuropsychological Screening Battery-II (SNSB-II), while depressive symptoms were measured with the Geriatric Depression Scale (GDepS). We analyzed differences in depressive symptoms based on APOE ε4 carrier status and levels of cognitive impairment, as well as their interaction. The results revealed that APOE ε4 carriers had significantly higher levels of depressive symptoms compared to non-carriers (p=.032), aligning with previous research. Additionally, depressive scores varied significantly across cognitive impairment groups (p=.018), with post hoc analyses indicating that individuals with dementia reported higher depressive scores than those with mild cognitive impairment. Although the main effects were significant, the interaction effect was not. These findings suggest that older adults carrying the APOE ε4 allele may need regular monitoring and proactive mental health interventions for depressive symptoms, even in the absence of significant cognitive decline. Furthermore, this study provides essential data for developing personalized mental health management models that take genetic risk factors for depression into account.
Disordered eating attitudes encompass maladaptive behaviors related to eating, including restrictive eating and binge eating. These attitudes significantly impact quality of life and are believed to be closely linked to awareness, which is the ability to recognize and respond to internal experiences and external stimuli. However, research exploring the specific mechanisms that connect awareness to disordered eating attitudes is limited. This study aimed to investigate whether emotional dysregulation mediates the relationship between awareness and disordered eating attitudes, and whether this association varies by age group. To achieve this, the Korean version of the Multidimensional Awareness Scale, the Difficulties in Emotion Regulation Scale, and the Korean version of the Eating Attitudes Test were administered to 799 adults aged 19 and older. Correlation analysis, mediation analysis, and moderated mediation analysis were performed on the collected data. The results showed that awareness was significantly negatively associated with both disordered eating attitudes and emotional dysregulation, while emotional dysregulation was positively associated with disordered eating attitudes. Mediation analysis further confirmed that emotional dysregulation mediated the relationship between awareness and disordered eating attitudes, with the significance of the indirect effect varying by age. Finally, the theoretical and practical implications of these findings are discussed.
This study investigated the relationship between anxiety and emotion regulation variability (ERV) using ecological momentary assessment (EMA). A total of 106 undergraduate students completed self-report questionnaires to measure baseline anxiety symptoms, followed by a 7-day EMA protocol that included three prompts per day to assess their daily use of emotion regulation strategies. ERV was calculated based on within-strategy and between-strategy variability by strategy type (total, adaptive, maladaptive). Multilevel analysis revealed that after controlling for mean levels of strategy use, adaptive within-strategy variability was significantly positively associated with anxiety symptoms, while other types of variability showed no significant association. This study is the first to examine ERV across strategy types in relation to anxiety, highlighting the importance of understanding intra-individual dynamics over time in anxiety-related emotion regulation patterns. Additionally, the findings contribute to the expanding literature on ERV and provide preliminary insights into its implications.
This study aimed to explore the relationships among negative affectivity, experiential avoidance, and cognitive flexibility in predicting YouTube overdependence among university students. A total of 300 students aged 19 and older participated in an online survey. The data were analyzed using descriptive statistics, Pearson’s correlations, and structural equation modeling (SEM) with Jamovi. The results revealed that negative affectivity directly increased YouTube overdependence and also influenced it indirectly through experiential avoidance. Experiential avoidance was found to significantly predict YouTube overdependence and partially mediated the effect of negative affectivity. Additionally, cognitive flexibility moderated the relationship between experiential avoidance and YouTube overdependence, demonstrating a conditional indirect effect: the indirect effect was stronger at lower levels of cognitive flexibility and nonsignificant at higher levels. These findings suggest that cognitive flexibility serves as a psychological protective factor, highlighting important theoretical and practical implications for preventing and addressing digital addiction.
This study aimed to investigate the serial mediating effects of maladaptive cognitive emotion regulation strategies and fear of missing out (FoMo) on the relationship between temperament and smartphone overdependence. We administered self-report questionnaires to 259 young adults aged 18 to 26, excluding any insincere responses. The questionnaires included the Temperament and Character Inventory-Revised Short (TCI-RS), the Smartphone Addiction Scale Based on Behavioral Addiction (SAS-B), the Cognitive Emotion Regulation Questionnaire (CERQ), and a modified version of the Fear of Missing Out Scale (FoMO). Data were analyzed using SPSS 26.0, and we examined sequential mediation effects with Process Macro Model 6. The statistical significance of these effects was assessed through bootstrapping procedures as recommended by Hayes (2018). The results indicated that novelty seeking (NS) and harm avoidance (HA) temperaments were positively correlated with smartphone overdependence, maladaptive cognitive emotion regulation strategies, and FoMO. Additionally, we found a significant partial mediation effect where NS temperament predicted smartphone overdependence through the serial mediation of maladaptive cognitive emotion regulation and FoMO. Similarly, HA temperament demonstrated a significant partial mediation effect through the same mediators. Thus, addressing cognitive distortions or modifiable beliefs may help reduce smartphone overdependence, while temperament, as a relatively stable internal trait, may contribute to it.
This study explored the effects of workplace gaslighting on employees' mental health, focusing on the mediating role of basic psychological needs satisfaction-specifically autonomy, competence, and relatedness-within the work environment A total of 700 full-time employees in South Korea participated in a cross-sectional survey, and structural equation modeling was used to test the proposed model. The findings revealed that workplace gaslighting significantly diminished the satisfaction of autonomy and relatedness needs, while competence was not notably impacted. Consequently, satisfaction in autonomy and relatedness was positively linked to subjective well-being and negatively correlated with depression and anxiety. Mediation analyses indicated that workplace gaslighting indirectly lowered subjective well-being by decreasing autonomy and relatedness satisfaction. Importantly, relatedness satisfaction emerged as a crucial mediator in mitigating the effects of gaslighting on depression and anxiety. These results emphasize the harmful effects of gaslighting on employees’ mental health and highlight the need for organizational practices that enhance psychological need satisfaction to create a healthier work environment.
This study explored the sequential mediating effects of self-differentiation and passive coping strategies on the relationship between insecure adult attachment and tendencies toward social networking site(SNS) addiction among university students. A survey was conducted with 387 students currently enrolled or on leave from four-year universities across South Korea who use SNS. Participants completed the Experiences in Close Relationships-Revised (ECR-R), the SNS Addiction Scale, the Self-Differentiation Scale, and the Stress Coping Inventory (K-CSI). The collected data were analyzed using SPSS 27.0 and the SPSS PROCESS Macro version. 4.2. The findings are summarized as follows. First, correlation analyses revealed significant relationships among insecure adult attachment, SNS addiction tendencies, self-differentiation, and passive coping strategies. Second, insecure adult attachment had not only directly influenced SNS addiction tendencies but also had an indirect effect through sequential mediation. Specifically lower self-differentiation led to increased passive coping strategies, which in turn heightened SNS addiction tendencies. These results underscore the importance of enhancing self-differentiation, enabling individuals to recognize their emotions and thoughts independently, and adaptive coping strategies in stressful situations to mitigate SNS addiction tendencies among university students. Therefore, the findings suggest that counseling and educational interventions focused on self-awareness and emotion regulation may effectively reduce SNS addiction tendencies in this population.
This study compared the effectiveness of an online Behavioral Activation (BA) program that included informational support messages for individuals with Complex Regional Pain Syndrome (CRPS), focusing on the impact of social comparison content. Four participants with CRPS were randomly assigned to either an experimental group (which received informational support plus social comparison content) or a control group (which received informational support only). An eight-session online BA intervention was conducted using a multiple-baseline design. All participants monitored their daily activities, and during the intervention phase, informational support messages were sent immediately after each submission. The experimental group also received social comparison information regarding other participants. Outcomes were evaluated at pre-, post-, and follow-up stages, measuring pain intensity, pain interference, pain catastrophizing, depressive symptoms, life satisfaction, and activity patterns. Effect sizes (Cohen’s d) were calculated. Both groups experienced increases in goal-directed activity. In the experimental group, pain intensity fluctuated, while it generally increased in the control group. Depression levels rose in the experimental group but fell in the control group. At follow-up, the experimental group exhibited at least small effects on all variables except for pain intensity, pain interference, pain-contingent persistence, and pacing for the purpose of increasing activity level and reducing pain. The control group also showed at least small effects, except for pain intensity, pain-contingent persistence, and pacing strategies aimed at conserving energy for valued activities and reducing pain. These findings suggest that an online BA program enhanced with informational support may benefit individuals with CRPS, although the inclusion of social comparison information appeared to have limited additional effects.
