Objective : The 18-item Obsessive-Compulsive Inventory-Revised (OCI-R) is widely employed to assess symptoms of obsessive-compulsive disorder (OCD). However, this instrument's factor structure does not align with contemporary dimensional models of OCD. Therefore, the objective of this study was to examine psychometric properties of the 12-item Korean OCI (OCI-12) on four obsessive-compulsive symptom dimensions, in patients with OCD. Methods : A total of 157 patients with OCD and 51 healthy controls completed psychological measures, including the OCI-R, Dimensional Obsessive-Compulsive Scale (DOCS), and scales evaluating anxiety and depressive symptoms. Pychometric characteristics of the OCI-12 with three neutralizing and three hoarding items eliminated from the OCI-R, were analyzed. Results : All OCI-12 items registered excellent internal consistency at 0.83. Confirmatory factor analysis revealed strong association between individual items and their proposed latent factors (i.e., subscales). Convergent validity was appropriate. A high correlation was particularly observed for the DOCS score (r=0.71, p<0 .001). Moreover, the OCI-12 was as sensitive as the OCI-R for determining effects of empirically supported treatment for OCD. Conclusion : The OCI-12 is a 12-item measure that adheres to the prevailing 4-factor model of OCD dimensions. Like OCI-R, it possesses good to excellent psychometric properties, including reliability, validity, and sensitivity to treatment.

The purpose of this study is to understand the effect of membership type for subscription service (individual subscription vs. group subscription) on continuous intention, and to verify the mediating effect of ease of justification and the moderated mediating effect of uncertainty. An experiment was conducted on 78 university students. As a result, consumers who use subscription services in group subscription showed higher intention to continue using the subscription service than consumers who use the subscription service in individual subscription. Also, the ease of justification mediates the effect on the intention to continue using. In addition, uncertainty was found to moderating effect of ease of justification on continuous use intention according to the type of subscription. This study understands the psychological mechanism of consumers according to the type of subscription service subscription and provides useful implications for companies that provide subscription services.

The present study examined whether individuals would respond differently, as a function of cultural self-orientations, when their requests were rejected. Also examined was whether individuals with different cultural self-orientations would predict differently how their interaction partner would respond when they rejected his or her request. Furthermore, it was investigated whether experimentally induced perspective-taking would influence responses to rejection and predictions of responses to rejection. It was found that responses to rejection as well as predictions of responses to rejection varied as a function of individual's independent self-orientation and perspective-taking. However, no significant effects were found with regard to interdependent self-orientation. Based on these results, the implications that cultural self-orientations have for request rejection and social behavior in general are discussed, and future directions are suggested.

Objectives: The coronavirus disease (COVID-19) pandemic has had various effects on mankind, especially children and adolescents. Because children and adolescents spend a lot of time at school, COVID-19 has had a great impact on school mental health. In this study, we investigated the effect of prolonged COVID-19 on school mental health. Methods: We prepared self-report questionnaires for depression (Children's Depression Inventory, CDI), anxiety (Korean version of the Penn State Worry Questionnaire for Children; Generalized Anxiety Disorder-7, GAD-7), and post-traumatic stress (Primary Care Post-traumatic Stress Disorder, PC-PTSD) for administering to students aged between 7 and 18 years, recruited by a COVID-19 psychological prevention support group in the Gwangmyeong Mental Health Welfare Center for 2 years, in 2020 and 2021. Results: For children aged 7-12 years, there was no significant difference between the years 2020 and 2021 in the assessment of depression, anxiety, and post-traumatic stress. Conversely, for adolescents aged 13-18 years, there was a significant increase in the scale scores (CDI, PC-PTSD, and GAD-7). Conclusion: Prolonged COVID-19 might have had a significant impact on the mental health of adolescents who spent a lot of time at school. When comparing the years 2020 and 2021, middle and high school students were more affected by COVID-19 than elementary school students.

PURPOSE. This study aimed to compare the bite force (BF) between complete dentures and implant overdentures (IODs) retained by two mandibular implants. Additionally, we evaluated the quality of life (QoL) and patient satisfaction among individuals using IODs. In addition, the effects of demographic parameters such as age and sex, and clinical parameters such as implant length, implant diameter, attachment height, attachment color, and interimplant distance on BF, QoL, and patient satisfaction were evaluated. MATERIALS AND METHODS. A total of 51 edentulous patients rehabilitated with the maxillary complete dentures and mandibular IODs retained by two implants were included in this study. BF was measured using a force meter pre- and post-implant in the same patients. Oral health-related quality of life (OHRQoL) was assessed with the Oral Health Impact Profile (OHIP-14) and patient satisfaction was assessed with the Visual Analog Scale (VAS) questionnaires. RESULTS. It was found that BF values were statistically higher for IODs than complete dentures (P < .001). In terms of attachment height of the OHIP scores, there was a significant difference in the psychological disability and social disability domains (P < .05). When examining the change in patient satisfaction as a function of sex, it was found that mandibular retention satisfaction differed significantly by sex (P < .05), but there was no significant difference in the other domains. CONCLUSION. Within the limitations of this study, it was observed that the BF increased after the use of IODs. Several factors, including age, interimplant distance, attachment height, and attachment color, were found to impact OHRQoL. Sex and implant diameter were identified as factors affecting patient satisfaction.

Purpose: This study aimed to investigate the effects of health-promoting behaviors (HPB), marital intimacy, and parenting stress on the quality of life (QoL) of low-income women with young children in Korea, an underserved group. Methods: This cross-sectional survey employed a descriptive correlational design. Using convenience sampling, 123 low-income women with children younger than 6 years were recruited from 14 health and community centers in Jeonju, Korea, from June 2020 to May 2021. Participants completed a questionnaire on QoL, HPB, marital intimacy, and parenting stress. Data were analyzed using descriptive statistics, independent t-test, analysis of variance, Pearson correlation, and hierarchical regression analysis. Results: Participants, who were on average 37.41±3.65 years old and had 1 to 2 children (n=98, 79.7%), reported a mid-level (3.14 out of 1-5) of QoL. Marital intimacy (β=.38, p<.001) was the most influential factor on the QoL of low-income women with young children. In descending order, HPB (β=.35, p<.001) and non- employment status (β=-.21, p=.003) had a significant influence on QoL (F=15.64, p<.001), and the overall explanatory power was 49.0%. Conclusion: Considering the mid-level QoL of low-income women with young children, programs aimed at improving the QoL of low-income women need to promote marital intimacy and maintain HPB, while considering their employment status. Strategies that include couple counseling, health care to encourage healthy lifestyles, and reemployment education are needed.

This study is a qualitative study to identify the educational needs for home-based lung cancer patients receiving chemotherapy. The study participants were 20 patients with home-based lung cancer patients receiving chemotherapy at a university hospital at D city. Data collected through interviews from July 2016 to September 2017 were analyzed using Krippendorff's method. As a result, 3 categories, 9 themes, 19 sub-themes, and 54 meaningful statements were derived. The three categories of educational needs were 'psychological needs', 'knowledge needs', and 'social needs'. Home-based lung cancer patients receiving chemotherapy wanted to support prognosis and stress and receive accurate knowledge of side effects and information on social support systems through education. The results of this study are expected to be used as basic data for the development of educational intervention programs for home-based lung cancer patients receiving chemotherapy in the future.

Background: Healthcare workers perform an emotionally exhausting daily work activity, making them prone to occupational hazards, namely psychosocial ones. This study aims to assess the impact of psychosocial risk factors on healthcare workers' mental health. Methods: A cross-sectional study was developed between May and June of 2021 with 479 healthcare workers from Portuguese hospitals. The Depression, Anxiety and Stress Scale was used to assess mental health, and psychosocial risks were assessed through the Health and Work Survey - INSAT. Statistical analysis was performed to identify the psychosocial risk factors related to anxiety, depression, and stress. Subsequently, a multiple linear regression was performed to identify the models that better explained psychosocial risk factors' relationship with anxiety, depression, and stress. Results: Data showed a strong exposure to psychosocial risks. Work pace and intensity, work relationships, and emotional demands stood out with higher global average percentages for yes answers to "exposure and discomfort." The analysis of the b values and p-values from the multiple linear regression shows that some cross-sectional psychosocial risks are predictors of anxiety and stress dimensions, and other psychosocial risks differ in the two mental health dimensions. However, it is important to highlight that healthcare workers still showed great joy and pleasure in performing their work activities. Conclusion: Support network development in the work environment is needed to prevent healthcare workers' emotional stress and promote their psychological well-being. Therefore, new research is essential to understand the psychosocial risks that affect healthcare workers and assess the less visible effects of work-health relationships.

Present study was conducted to explore the effect of productive reading habit (PRH) and construal of reading on reading performance, and to identify any psychological differences between those who read continuously and those who do not. For this purpose, 309 adolescents were divided into a group with a lowly level of productive reading habit(PRH) and a group with a highly level of PRH, and a concrete(why) versus abstract(how) construal of reading were primed, and reading performance were investigated for 6 weeks. After that, chi-square analysis and analysis of variance were performed on the collected data. As a result, the group with highly PRH had more days of reading and longer total reading time than the group with lowly PRH. Also, in the group with a highly PRH, the number of days of reading and reading time did not differ according to the construal of reading. On the other hand, the group with a lowly PRH had more reading days and a longer total reading time under the condition of concrete construal of reading than the condition of abstract construal. This study shows that a concrete construal can be helpful in enabling people with lowly productive habit(PH) to initiate a task and maintain concentration to the task.

The purpose of this study was to examine whether gender collective self-esteem would moderate the relationship between perceived gender discrimination and belief in a just world (BJW) after controling the effect of personal self-esteem. For this, we measured perceived gender discrimination, personal self-esteem, gender collective self-esteem, and BJW in a sample of 300 women and conducted hierarchical regression analysis. The results revealed that, after controlling the effect of personal self-esteem, gender collective self-esteem moderated the association between perceived gender discrimination and BJW. That is, as gender collective self-esteem became greater, the negative effect of perceived gender discrimination on BJW decreased. In addition, we tested if four aspects of gender collective self-esteem (e.g. membership, private, public, identity) moderated the relationship between perceived gender discrimination and BJW. It was found that all of the four aspects except identity had significant moderating effects. Finally, we discussed limitations, suggestions for future research and clinical implications.
