Jung M, Lee SB, Lee JW, Park YR, Chung H, Min YH, Park HJ, Lee M, Chung S, Son BH, Ahn SH, Chung IY. The Impact of a Mobile Support Group on Distress and Physical Activity in Breast Cancer Survivors: Randomized, Parallel-Group, Open-Label, Controlled Trial. J Med Internet Res 2023; 25:e47158. [PMID: 37549004 PMCID: PMC10442738 DOI: 10.2196/47158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 06/06/2023] [Accepted: 07/04/2023] [Indexed: 08/08/2023] Open
Abstract
BACKGROUND While mobile health apps have demonstrated their potential in revolutionizing health behavior changes, the impact of a mobile community built on these apps on the level of physical activity and mental well-being in cancer survivors remains unexplored. OBJECTIVE In this randomized controlled trial, we examine the effects of participation in a mobile health community specifically designed for breast cancer survivors on their physical activity levels and mental distress. METHODS We performed a single-center, randomized, parallel-group, open-label, controlled trial. This trial enrolled women between 20 and 60 years of age with stage 0 to III breast cancer, an Eastern Cooperative Oncology Group performance status of 0, and the capability of using their own smartphone apps. From January 7, 2019, to April 17, 2020, a total of 2,616 patients were consecutively screened for eligibility after breast cancer surgery. Overall, 202 patients were enrolled in this trial, and 186 patients were randomly assigned (1:1) to either the intervention group (engagement in a mobile peer support community using an app for tracking steps; n=93) or the control group (using the app for step tracking only; n=93) with a block size of 10 without stratification. The mobile app provides a visual interface of daily step counts, while the community function also provides rankings among its members and regular notifications encouraging physical activity. The primary end point was the rate of moderate to severe distress for the 24-week study period, measured through an app-based survey using the Distress Thermometer. The secondary end point was the total weekly steps during the 24-week period. RESULTS After excluding dropouts, 85 patients in the intervention group and 90 patients in the control group were included in the analysis. Multivariate analyses showed that patients in the intervention group had a significantly lower degree of moderate to severe distress (B=-0.558; odds ratio 0.572; P<.001) and a higher number of total weekly step counts (B=0.125; rate ratio 1.132; P<.001) during the 24-week period. CONCLUSIONS Engagement in a mobile app-based patient community was effective in reducing mental distress and increasing physical activity in breast cancer survivors.

Delayed Mid-Sleep Time Associated With Weight Gain While Controlling for Eating Behaviors and Attention Deficit Hyperactivity Disorder Symptoms During the COVID-19 Pandemic. Psychiatry Investig 2023; 20:768-774. [PMID: 37559450 PMCID: PMC10460974 DOI: 10.30773/pi.2022.0326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 04/12/2023] [Accepted: 05/31/2023] [Indexed: 08/11/2023] Open
Abstract
OBJECTIVE Society's sleep-wake cycle and eating behaviors have altered and are considered the psychological outcomes of the coronavirus disease-2019 (COVID-19) pandemic. Our aim was to examine the relationship between sleep-wake rhythms, eating behaviors (dieting, oral control, and bulimic behaviors), and attention deficit hyperactivity disorder (ADHD) symptoms with weight gain during the COVID-19 pandemic. METHODS The participants were 578 female university students divided into three groups based on weight change during COVID-19 who lost weight, whose weight did not change (nWC), and who gained weight (WG). The participants' information about weight change in the last year and responses to the Pittsburg Sleep Quality Index, Eating Attitudes Test, Adult ADHD Severity Rating Scale, and Wender Utah Rating Scale were collected via an online survey from January 8, 2021 to January 11, 2021. RESULTS The sleep-wake phase was more delayed in WGs than in the other two groups. The bulimic behavior score was higher and the oral control behavior score was lower in the WG group than in the nWC group. A hierarchical regression analysis model, in which weight change scores were dependent variables, showed that mid-sleep time in second step (β=4.71, t=2.18, p=0.03), and oral control (β=-0.11, t=-3.24, p=0.001)/bulimic behaviors (β=0.20, t=3.20, p=0.001) in third step were associated with weight change after controlling for both current and childhood ADHD symptoms. CONCLUSION Chronotherapeutic approaches that regulate sleep-wake rhythm may facilitate weight control of individuals during stressful periods, such as the COVID-19 outbreak.

Psychometric properties of the Korean version of questionnaires on adherence to physical distancing and health beliefs about COVID-19 in the general population. Front Psychiatry 2023; 14:1132169. [PMID: 37484663 PMCID: PMC10356985 DOI: 10.3389/fpsyt.2023.1132169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Accepted: 05/04/2023] [Indexed: 07/25/2023] Open
Abstract
Introduction We aimed to examine the psychometric properties of the Korean version of the questionnaires on adherence to physical distancing and health beliefs about COVID-19 in the general population in South Korea. In addition, we investigated how the various sections interacted with each other and with viral anxiety and depression, and ultimately affected adherence to physical distancing. Methods An anonymous online survey was conducted among members of the general population in South Korea between 10 and 18 January 2022. We recruited 400 respondents and measured their demographic information, symptoms, and responses to questions about COVID-19. First, we examined the reliability and validity of the questionnaires, which included questions about people's adherence to physical distancing guidelines and COVID-19-related health beliefs. Second, we examined the relationship between physical distancing and viral anxiety or depression, as assessed using the six-item Stress and Anxiety to Viral Epidemics (SAVE-6) scale and the Patient Health Questionnaire-9 (PHQ-9). Results All 400 participants (204 men, age 41.6 ± 10.8) completed the survey. Confirmatory factor analysis revealed a good model fit for adherence to physical distancing (CFI = 1.000, TLI = 1.019, RMSEA = 0.000, and SRMR = 0.034) and health beliefs about COVID-19 (CFI = 0.993, TLI = 0.991, RMSEA = 0.030, and SRMR = 0.052). It also showed good reliability for Factor I (Cronbach's α = 0.826) and Factor II (α = 0.740). Four categories of the COVID-19 health beliefs questionnaire also showed good reliability for perceived susceptibility (α = 0.870), perceived severity (α = 0.901), perceived benefit (α = 0.935), and barriers to following physical distancing (α = 0.833). Structural equation models showed that the effects of health beliefs and viral anxiety and depression were mediated mostly by personal injunctive norms. Goodness-of-fit measures indicated a good fit. (Chi-square = 24.425, df = 7, p < 0.001; CFI = 0.966; RMSEA = 0.079). Conclusion The Korean version of the COVID-19 adherence to physical distancing and health beliefs questionnaires showed good reliability and validity in the Korean general population. In addition, the effects of health beliefs, along with viral anxiety and depression, were mainly mediated by personal injunctive norms.

Psychiatry Investig 2023; 20:524-530. [PMID: 37357668 DOI: 10.30773/pi.2023.0019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 03/12/2023] [Indexed: 06/27/2023] Open
Abstract
OBJECTIVE We aimed to explore the association between academic stress or motivation and the psychological well-being of medical students during the coronavirus disease-2019 (COVID-19) pandemic. We also explored the effects of their resilience or viral anxiety on this association. METHODS This online surveyed for medical students was done during October 20-28, 2021. Participants' age, sex, grades, and COVID-19-related experiences were collected. Their symptoms were measured with Stress and Anxiety to Viral Epidemics-6 items, Medical Stress Scale (MSS), intrinsic motivation using Academic Motivation Scale, Connor Davidson Resilience Scale-2 items (CD-RISC2), the 5-item World Health Organization Well-Being Index (WHO-5), and GRIT scale. RESULTS Among 251 medical students, linear regression performed to explore the predicting factors for psychological well-being or medical stress showed that WHO-5 score was predicted by age (β=0.16, p=0.02) and CD-RISC2 (β=0.29, p<0.001) (F=15.5, p<0.001). In addition, the MSS score was predicted by age (β=0.20, p=0.004), intrinsic motivation (β=-0.31, p<0.001), GRIT (β=0.21, p=0.003), and CD-RISC2 (β=-0.31, p<0.001) (F=15.6, p<0.001). The resilience of medical students partially influenced their intrinsic motivation, affecting their psychological well-being or academic stress. However, no significant association was observed in the case of viral anxiety as a mediator, indicating that viral anxiety did not mediate the association. CONCLUSION This study highlights the importance of resilience in mediating the relationship between intrinsic motivation and psychological well-being or academic stress. However, viral anxiety was not found to be a mediator in this relationship.

Abstract
Fertility preservation is a major concern in young patients diagnosed with breast cancer and planning to receive multimodality treatment, including gonadotoxic chemotherapy with or without age-related decline through long-term endocrine therapy. Most breast cancer patients undergo multimodality treatments; many short-term and long-term side effects arise during these therapies. One of the most detrimental side effects is reduced fertility due to gonadotoxic treatments with resultant psychosocial stress. Cryopreservation of oocytes, embryos, and ovarian tissue are currently available fertility preservation methods for these patients. As an adjunct to these methods, in vitro maturation or gonadotropin-releasing hormone agonist could also be considered. It is also essential to communicate well with patients in the decision-making process on fertility preservation. It is essential to refer patients diagnosed with breast cancer on time to fertility specialists for individualized treatment, which may lead to desirable outcomes. To do so, a multimodal team-based approach and in-depth discussion on the treatment of breast cancer and fertility preservation is crucial. This review aims to summarize infertility risk related to currently available breast cancer treatment, options for fertility preservation and its details, barriers to oncofertility counseling, and psychosocial issues.

Abstract
OBJECTIVE We aimed to explore whether nursing professionals' psychological states affect their grief response for a patient's death in the coronavirus disease-2019 (COVID-19) inpatients' ward. METHODS Survey was conducted among frontline nursing professionals working in COVID-19 inpatients wards at three tertiary-level affiliated hospitals of the University of Ulsan during April 7-26, 2022. Participants' information such as age, years of employment, or marital status were collected, and their responses to rating scales including Pandemic Grief Scale (PGS) for healthcare workers, Stress and Anxiety to Viral Epidemics-9 items (SAVE-9), Patient Health Questionnaire-9 (PHQ-9), Loneliness and Social Isolation Scale, and Insomnia Severity Scale (ISI) were collected. RESULTS All 251 responses were analyzed. We observed that 34% reportedly suffered from depression. The linear regression analysis showed that a high PGS score was expected by high SAVE-9 (β=0.12, p=0.040), high PHQ-9 (β=0.25, p<0.001), high loneliness (β=0.17, p=0.006), and high ISI score (β=0.16, p=0.006, F=20.05, p<0.001). The mediation analysis showed that the depression of nursing professionals directly influenced their pandemic grief reaction, and their work-related stress and viral anxiety, insomnia severity, and loneliness partially mediated the association. CONCLUSION We confirm that frontline nursing professionals' depression directly influenced their grief reaction, and their work-related stress and viral anxiety, insomnia severity, and loneliness partially mediated the association. We hope to establish a psychological and social support system for the mental health of nurses working in the COVID-19 wards.

Abstract
Background and Objective We aimed to investigate whether viral anxiety affects insomnia severity in patients with insomnia disorder during the coronavirus disease 2019 (COVID-19) pandemic. In addition, we examined whether viral anxiety mediates the influence of dysfunctional beliefs about sleep on insomnia severity.Methods The medical records of 111 patients who visit the sleep clinic from September 2021 to May 2022 were reviewed. Patients’ symptoms were rated with rating scales including Insomnia Severity Index (ISI), Stress and Anxiety to Viral Epidemics-6 items (SAVE-6), Dysfunctional Beliefs and Attitudes about Sleep-16 items (DBAS-16), Patient Health Questionnaire-9 items (PHQ-9), Epworth Sleepiness Scale, and discrepancy between desired time in bed and desired total sleep time (the DBST index).Results The SAVE-6 score was not significantly correlated with ISI score among insomnia patients. Linear regression analysis showed that the ISI score was expected by PHQ-9 (β = 0.21, p = 0.038) and DBAS-16 (β = 0.42, p < 0.001). Mediation analysis showed that viral anxiety did not mediate the influence of dysfunctional beliefs about sleep on insomnia severity.Conclusions We could not observe the mediating effect of viral anxiety on the association between dysfunctional beliefs about sleep on insomnia severity. Though COVID-somnia was one of big issues in this COVID-19 pandemic, the influence of virus on the severity of insomnia among insomnia patients needs to be interpreted cautiously.

Abstract
BACKGROUND Previous studies have suggested that parental cognitions about child's sleep may be an important factor underlying pediatric sleep problems. The current study aimed to (a) develop an assessment tool measuring parental understanding and misperceptions about baby's sleep (PUMBA-Q); (b) validate the questionnaire using self-report and objective sleep measures. METHODS There were 1,420 English-speaking caregivers (68.0% mothers, 46.8% of children being females, mean age 12.3 months), who has completed online self-reported questionnaires. The PUMBA-Q, which was developed for this study, Dysfunctional Beliefs and Attitudes about Sleep (DBAS) and Maternal Cognitions about Infant Sleep Questionnaire (MCISQ) were included to evaluate participant's thoughts on their own or child's sleep. Insomnia Severity Index (ISI) was collected to access participant's subjective insomnia severity. Brief Infant Sleep Questionnaire-Revised (BISQ-R) was used to assess parental-reported child sleep. Auto-videosomnography was used to record child's sleep. RESULTS Exploratory factor analysis indicated the best fit with a 4-factor model using 23 items (RMSEA = .039). The four subscales were labeled: (a) Misperceptions about parental intervention; (b) Misperceptions about feeding; (c) Misperceptions about child's sleep; and (d) General anxiety of parents. Internal consistency was adequate (Cronbach's alpha = .86). PUMBA-Q scores were significantly associated with MCISQ (r = .64, p < .01), DBAS (r = .36, p < .01), ISI (r = .29, p < .01), BISQ-R (r = .-49, p < .01), objective child's total sleep time (r = -.24, p < .01) and objective number of parental nighttime visits (r = .26, p < .01). CONCLUSIONS The results demonstrated that PUMBA-Q 23 is a valid assessment tool for parental cognitions of child sleep. The link between parental cognitions and child sleep highlights the importance of managing parental cognitions about child sleep when treating pediatric sleep problems.

Abstract
OBJECTIVES To document the level of vaccine hesitancy in caregivers' of children younger than 12 years of age over the course of the pandemic in Pediatric Emergency Departments (ED). Study design Ongoing multicenter, cross-sectional survey of caregivers presenting to 19 pediatric EDs in the USA, Canada, Israel, and Switzerland during first months of the pandemic (phase1), when vaccines were approved for adults (phase2) and most recently when vaccines were approved for children (phase3). RESULTS Willingness to vaccinate rate declined over the study period (59.7%, 56.1% and 52.1% in the three phases). Caregivers who are fully vaccinated, who have higher education, and those worried their child had COVID-19 upon arrival to the ED, were more likely to plan to vaccinate in all three phases. Mothers were less likely to vaccinate early in the pandemic, but this hesitancy attenuated in later phases. Older caregivers were more willing to vaccinate, and caregivers of older children were less likely to vaccinate their children in phase 3. During the last phase, willingness to vaccinate was lowest in those who had a primary care provider but did not rely on their advice for medical decisions (34%). Those with no primary care provider and those who do and rely on their medical advice, had similar rates of willingness to vaccinate (55.1% and 52.1%, respectively). CONCLUSIONS COVID-19 vaccine hesitancy is widespread and growing over time, and public health measures should further try to leverage identified factors associated with hesitancy in order to enhance vaccination rates among children.

Abstract
OBJECTIVE This study explored the psychometric properties of the Chinese version of the Stress and Anxiety to Viral Epidemics-6 Items (SAVE-6) scale for cold chain practitioners exposed to moderate-to-high risk of infection. METHODS A total of 233 cold chain practitioners participated in an anonymous online survey, conducted from October to November 2021. The questionnaire comprised participant demographic characteristics, the Chinese version of SAVE-6, the Generalized Anxiety Disorders-7 (GAD-7), and the Patient Health Questionnaire-9 (PHQ-9) scales. RESULTS Based on the results of the parallel analysis, the single-structure model of the Chinese version of SAVE-6 was adopted. The scale showed satisfactory internal consistency (Cronbach's alpha=0.930) and good convergent validity based on Spearman's correlation coefficient with the GAD-7 (rho=0.616, p<0.001) and PHQ-9 (rho=0.540, p<0.001) scale scores. The optimal cutoff score for Chinese Stress and Anxiety to Viral Epidemics-9 Items was identified as ≥12 (area under the curve=0.797, Sensitivity=0.76, Specificity=0.66) for cold chain practitioners. CONCLUSION The Chinese version of the SAVE-6 scale has good psychometric properties and can be applied as a reliable and valid rating scale to assess the anxiety response of cold chain practitioners in the post-pandemic era.

Abstract
Introduction Nurses have been repeatedly exposed to unexpected death and grief during COVID-19 pandemic, and it is necessary to provide grief support for the nurses who have experienced the loss of patients to COVID-19. We aimed to explore the reliability and validity of the Pandemic Grief Scale (PGS) for Healthcare Workers among frontline nursing professionals working in COVID-19 inpatient wards whose patients may have died. Methods An anonymous online survey was performed among frontline nursing professionals working in COVID-19 wards in three tertiary-level general hospitals in Korea between April 7 and 26, 2021. In total, 229 from participants who confirmed they had witnessed death of patients were employed for the statistical analysis. The survey included demographic characteristics and rating scales, including the Korean version of the PGS for Healthcare Workers, the Fear of COVID-19 scale, the Generalized Anxiety Disorder-7 items, and the Patient Health Questionnaire-9 items. Results The single-factor structure of the Korean version of the PGS for Healthcare Workers showed good fits for the model. The scale had good internal consistency and convergent validity with other anxiety and depression scales. Conclusion The Korean version of the PGS of Healthcare Workers was valid and reliable for measuring grief reactions among nursing professionals facing the pandemic. It will be helpful in evaluating the grief reaction of the healthcare workers and providing them with a psychological support system.

Abstract
Introduction This study aims to provide a scale for measuring problematic TikTok use levels by adapting items from the Instagram Addiction Scale. Methods The 372 participants were determined by a convenience sampling method, and data were collected through Google online forms. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed for construct validity and criterion-related validity analysis. Criterion-related validity for the Problematic TikTok Use Scale (PTTUS) was tested using correlation analysis between the Bergen Social Media Addiction Scale and Social Media Use Disorder Scale. Results EFA indicated that a three-factor structure should be formed. The first factor is the sub-dimension of obsession and consists of 4 items, the second factor is the escapism sub-dimension and consists of 6 items, and the third factor is the lack of control sub-dimension and consists of 6 items. The model fit for adapting the PTTUS into Turkish was examined with first-level CFA, χ2/sd, RMSEA, CFI, GFI, AGFI, and SRMR, the obtained values show that the three-factor structure of the scale provides acceptable fit. Reliability analyses showed that Cronbach's alpha internal consistency reliability coefficient ranged from 0.83 to 0.90; McDonald's Omega reliability values was 0.84 to 0.90, and test-retest correlation coefficient ranged from 0.68 to 0.73, indicating sufficient internal consistency and test-retest reliability. Conclusion Based on this information, PTTUS is a measurement tool with sufficient psychometric properties that can be applied to determine individuals' levels of problematic TikTok use.

Abstract
Background Insomniacs are heterogenous group with very diverse personalities. We aimed to investigate the mediating role of sleep reactivity (SR), sleep hygiene (SH), and sleep effort (SE) in the relationship between Type D personality and insomnia. Materials and methods We conducted a cross-sectional survey among 474 participants. The survey comprised the sociodemographic data form, Insomnia Severity Index (ISI), D Type Personality Scale (DS-14), Ford Insomnia Response to Stress Test (FIRST), Glasgow Sleep Effort Scale (GSES), and Sleep Hygiene Index (SHI). We conducted hierarchical multiple regression analysis to identify the associations between age, sex, SR, Type D personality traits, SE, SH, and insomnia severity. We subsequently conducted mediation analyses to examine whether SR, SH, and SE mediated the relationship between Type D personality and insomnia. Results ISI, DS-14, FIRST, SHI, and GSES scores were significantly higher in individuals with Type D personality. Female sex, SR, Type D personality traits, SE, and SH explained 45% of the variance in insomnia severity. When age, sex, insomnia response to stress, and Type D personality traits were controlled, SE and SH significantly explained 25% of the variance in insomnia severity (R 2 = 0.45, R 2 change = 0.25, F (6.474) = 65.58, p < 0.001). SR, SE, and SH each played a partial mediating role between Type D personality and insomnia. Conclusion The findings showed that individuals with Type D personality had high SR and that individuals with a higher number of these personality traits exhibited more severe insomnia symptoms through high SR, greater SE, and worse SH.

Abstract
Introduction During the COVID-19 pandemic, healthcare workers (HCWs) have been exposed to higher levels of anxiety and psychological stress than the general population. Nurses who cared for COVID patients could not avoid repeated mourning as they witnessed the deaths of their patients. Therefore, tools are needed to evaluate whether there is adequate support for the grieving process of HCWs in both qualitative and quantitative manners. Methods Data from 229 nurses who witnessed the deaths of COVID-19 inpatients were analyzed using an online survey of nurses working in three tertiary hospitals. Factor analysis was conducted to validate the 10-item Korean version of Grief Support in Healthcare Scale (GSHCS). Stress and Anxiety to Viral Epidemics-9 was used to measure stress and anxiety caused by coronavirus, Generalized Anxiety Disorder-7 was used to measure overall anxiety, and Patient Health Questionnaire-9 was used for depression. Convergent validity correlation analysis was also performed with GSHCS. Results The two-factor model showed a good fit for the 10-item GSHCS (χ 2 = 35.233, df = 34, p = 0.410, CFI = 0.999, TLI = 0.990, RMSEA = 0.013, SRMR = 0.064). Cronbach's alpha is 0.918 and McDonald's omega is 0.913, suggesting that the 10-item version of the GSHCS is reliable for determining psychometric properties. Conclusion According to this study, the 10-item Korean version of the GSHCS is a reliable and valid measure of psychological support for grief among frontline nursing professionals who have witnessed the deaths of patients they cared for while working in COVID-19 inpatient wards. A two-factor model of the GSHCS has a good model fit and good convergent validity with other rating scales that measure viral anxiety, depression, and general anxiety.

Abstract
Objective We adapted the Ford Insomnia Response to Stress Test to Turkish (FIRST-T) and validated it. Methods We randomly divided 774 Turkish university students into two equal groups for exploratory (EFA) and confirmatory factor analysis (CFA). McDonald's omega and Cronbach's alpha values were utilized for reliability analyses. Item response theory (IRT) approach also used for psychometric properties on the full sample. For discriminant validity, study sample were classified into high and low sleep reactivity groups, and their sociodemographic and sleep data were compared. Results EFA results suggested a one-factor structure of the FIRST-T, which was confirmed by CFA results. The FIRST-T had solid internal reliability. Item analysis results showed that all the items could distinguish between low and high scorers. This scale showed the same construct (clinical insomnia vs good sleepers) across the sexes in multi-group CFA and differential item functioning results. In the high FIRST-T score group, sleep quality, severity of insomnia, and anxiety scores were higher. In this group, more participants had clinical insomnia according to the Insomnia Severity Index (ISI) and were poor sleepers according to the Pittsburg Sleep Quality Index (PSQI) (p < 0.01). Conclusion The FIRST-T has robust psychometric properties that assesses sleep reactivity among university students.

Abstract
Background and Objective It is important to consider dysfunctional beliefs about sleep when conducting cognitive-behavioral therapy for insomnia. The purpose of this study was to examine the reliability and validity of a Dysfunctional Beliefs about Sleep-2 items (DBS-2) scale in a general population and clinical sample.Methods Our study examined the reliability and validity of the DBS-2 scale in the general population (group I, n = 374) and in a clinical sample of subjects with insomnia disorders (group II, n = 105). An online survey targeting the general population was conducted over the course of January 10–18, 2022, and a retrospective study of medical records was conducted among a clinical sample of insomnia patients who visited the Asan Medical Center Sleep Clinic for the first time between September of 2021 and May of 2022. The internal consistency reliability of the DBS-2 scale was measured using split-half coefficients, and factor analysis was used to determine its validity. Using the Insomnia Severity Index (ISI) and the Dysfunctional Beliefs and Attitudes about Sleep-16 items (DBAS-16), convergence validity was explored.Results Split-half coefficients for the DBS-2 were 0.862 and 0.855 in the general population and a clinical sample of insomnia disorder. DBS-2 overall report score was significantly correlated with ISI (r = 0.26, p < 0.001) and DBAS-16 (r = 0.43, p < 0.001) in the general population, and correlated with ISI (r = 0.45, p < 0.001) and DBAS-16 (r = 0.50, p < 0.001) in the clinical sample. Both groups of subjects had an optimal cut-off score of 13 for the DBS-2 scale.Conclusions We found that the DBS-2 scale, a two-item ultra-brief rating scale, could accurately measure dysfunctional beliefs about sleep in the general population and a clinical sample of insomnia patients.

Abstract
PURPOSE Physical activity (PA) in patients with breast cancer is associated with improved quality of life (QoL); however, many breast cancer survivors do not meet the recommended PA level. This study aims to evaluate the effect of digital health interventions using mobile apps to promote PA and QoL in patients with postoperative breast cancer. This study will also identify effective digital intervention methods and perform an economic analysis. The main hypothesis is that the use of mobile healthcare apps will improve health-related quality of life (HRQOL), promote PA, and reduce healthcare costs. METHODS The Promotion of a better lifestyle (PA) with Precise and Practicable digital healthcare in postoperative CANCER patients through a Multi-Disciplinary Network (P4CancerMDnet) study is examined by a prospective 4-group randomized controlled trial with a concurrent cost-utility evaluation. Patients are randomly assigned to 3 different mobile app intervention groups or control groups in a 1:1:1:1 ratio. The intervention group is encouraged to use the assigned mobile app. The targeted outcomes are HRQOL, metabolic health markers, and quality-adjusted life-years. The outcomes will be measured at the 6- and 12-month follow-ups. DISCUSSION This study will contribute towards a better lifestyle and HRQOL through digital healthcare for postoperative breast cancer patients. These findings are expected to provide evidence of the effectiveness of mobile apps for breast cancer survivors. TRIAL REGISTRATION Clinical Research Information Service Identifier: KCT0005447.

Abstract
BACKGROUND In treating colorectal cancer, surgical techniques and adjuvant treatments have advanced over the past century, but relatively less attention has been given to improve health-related quality of life (HRQOL). Recent studies report a significant association between cancer recurrence and patient lifestyle after surgery, hence emphasizing the need to assist patients to reduce this risk through appropriate lifestyle choices. The proposed study will evaluate the effects of digital interventions on lifestyle after surgery for colorectal cancer using mobile applications. METHODS A randomized controlled trial design was proposed. A total of 320 patients diagnosed with colorectal cancer aged between 20 and 70 years were to be enrolled and randomized in equal numbers into 4 groups (3 groups assigned to different mobile applications and a control group). Surveys that evaluate HRQOL, physical measurements, and metabolic parameters (fasting glucose, hemoglobin A1C, triglyceride, high-density lipoprotein cholesterol), and fat/muscle mass measurements by abdominal computed tomography (CT), will be conducted prior to surgery and every 6 months post-surgery for 18 months. Statistical analysis will be used to compare the outcomes between groups. DISCUSSION Results from this study could provide evidence that easily accessible mobile applications can influence patient lifestyles. Results showing minimal effects of such applications could also be constructive for improving healthcare-related applications.

Abstract
Background and Objective We considered the concept of the DBST, the discrepancy between a patient’s desired time in bed (TIB) and desired total sleep time (TST). The DBST index can be used to easily assess a patient’s thoughts on their desired TST and dysfunctionally long TIB. This study aimed to explore whether the DBST index can predict the severity of insomnia.Methods A total of 374 members of the general population participated in this e-survey study. The participants answered questions regarding their bedtime, sleep onset time, wake-up time, desired TST, and desired TIB, and psychological symptoms were assessed using the Insomnia Severity Index (ISI), Patients Health Questionnaire–9 items (PHQ-9), Dysfunctional Beliefs and Attitudes about Sleep–16 items (DBAS-16), and Glasgow Sleep Effort Scale (GSES).Results The DBST index was significantly correlated with the ISI (r = 0.20, p < 0.01), PHQ-9 (r = 0.15, p < 0.01), GSES (r = 0.14, p < 0.01), DBAS-16 (r = 0.16, p < 0.01), desired TST (r = -0.62, p < 0.01), and desired TIB (r = 0.52, p < 0.01). Linear regression analysis showed that insomnia severity was predicted by persistent preoccupation with sleep (beta = 0.64, p < 0.001), dysfunctional beliefs about sleep (beta = 0.06, p < 0.001), depression (beta = 0.23, p < 0.001), and DBST (beta = 0.32, p = 0.035). The DBST directly influenced insomnia severity, and this association was shown to be mediated by dysfunctional beliefs and attitudes about sleep, preoccupation with sleep, and depression.Conclusions The DBST index could be a possible new sleep index due to its relationship with insomnia severity, depression, dysfunctional beliefs about sleep, and preoccupation with sleep. Further studies are needed to explore the consistency of the clinical sample.

Abstract
BACKGROUND This study aimed to explore clinical correlates of fear of progression (FoP) among patients with cancer during the coronavirus disease 2019 (COVID-19) pandemic and examine the mediation effect of cancer-related dysfunctional beliefs about sleep (C-DBS). METHODS Medical charts of patients with cancer who visited a psycho-oncology clinic between July and November 2021 were reviewed. Baseline socio-demographic and cancer-related variables were collected. Patients' self-report questionnaires, regarding FoP, depression (Patient Health Questionnaire-9 items; PHQ-9), viral anxiety (Stress and Anxiety to Viral Epidemics-6 items; SAVE-6), C-DBS, and other distress, were investigated. Pearson's correlation and linear regression were performed to examine the risk factors of FoP. Mediation effect analysis with the bootstrap method with 2,000 resamples was implemented. RESULTS A total of 231 patients were included in the analysis. Linear regression revealed that FoP was predicted by age (β = -0.14, P = 0.003), PHQ-9 (β = 0.48, P < 0.001), SAVE-6 (β = 0.34, P < 0.001), and C-DBS (β = 0.15, P = 0.005). FoP was directly influenced by SAVE-6 and mediated by C-DBS, while it was directly influenced by PHQ-9 with no mediation effect. CONCLUSION During the COVID-19 pandemic, the FoP of patients with cancer was associated with younger age, depression, viral anxiety, and C-DBS. Depression and viral anxiety directly influenced FoP, while C-DBS mediated the association between viral anxiety and FoP. Therefore, oncology healthcare professionals are recommended to assess C-DBS of their patients when they are highly distressed from FoP.

Abstract
OBJECTIVE We aimed to examined the reliability and validity of Korean version of Social Distancing Phobia scale, and whether intolerance of uncertainty mediates the association of the general population's social distancing phobia with viral anxiety and depression. METHODS Through this anonymous online survey, we collected responses from 400 individuals in the general Korean population. Participants' demographic information and rating scales scores, including the Social Distancing Phobia scale, Stress and Anxiety to Viral Epidemics-6 items, Patient Health Questionnaire-9, and Intolerance of Uncertainty-12 items. RESULTS Confirmatory factor analysis showed a good model fit, and the Korean version of Social Distancing Phobia scale showed good internal consistency. Social distancing phobia was significantly correlated with age (r=0.213, p<0.001), viral anxiety (r=0.390, p<0.001), depression (r=0.244, p<0.001), and intolerance of uncertainty (r=0.323, p<0.001). A linear regression analysis showed that age (β=0.235, p<0.001), viral anxiety (β=0.281, p<0.001), depression (β=0.121, p=0.009), and intolerance of uncertainty (β=0.200, p<0.001; adjusted R2=0.246, F=33.6, p<0.001) predicted social distancing phobia. Mediation analysis revealed that viral anxiety directly influenced social distancing phobia (z=6.48, p<0.001), and intolerance of uncertainty partially mediated this association (z=2.92, p=0.003). CONCLUSION Social distancing phobia may cause psychological stress but may also increase adherence to physical distancing measures and prevent the spread of viruses.
