Development and Validation of a Smartphone Addiction Scale (SAS)

Objective The aim of this study was to develop a self-diagnostic scale that could distinguish smartphone addicts based on the Korean self-diagnostic program for Internet addiction (K-scale) and the smartphones own features. In addition, the reliability and validity of the smartphone addiction scale (SAS) was demonstrated. Methods A total of 197 participants were selected from Nov. 2011 to Jan. 2012 to accomplish a set of questionnaires, including SAS, K-scale, modified Kimberly Young Internet addiction test (Y-scale), visual analogue scale (VAS), and substance dependence and abuse diagnosis of DSM-IV. There were 64 males and 133 females, with ages ranging from 18 to 53 years (M = 26.06; SD = 5.96). Factor analysis, internal-consistency test, t-test, ANOVA, and correlation analysis were conducted to verify the reliability and validity of SAS. Results Based on the factor analysis results, the subscale “disturbance of reality testing” was removed, and six factors were left. The internal consistency and concurrent validity of SAS were verified (Cronbachs alpha = 0.967). SAS and its subscales were significantly correlated with K-scale and Y-scale. The VAS of each factor also showed a significant correlation with each subscale. In addition, differences were found in the job (p<0.05), education (p<0.05), and self-reported smartphone addiction scores (p<0.001) in SAS. Conclusions This study developed the first scale of the smartphone addiction aspect of the diagnostic manual. This scale was proven to be relatively reliable and valid.

Cognitive emotion regulation strategies contributing to resilience in patients with depression and/or anxiety disorders

OBJECTIVE Research suggests that resilience is associated with favorable treatment outcome in patients with depression and/or anxiety disorders. In this regard, the identification of specific characteristics related to resilience that could provide targets for resilience-enhancement interventions is needed. Since the type of cognitive coping strategies is a possible marker of resilience, we investigated adaptive and maladaptive cognitive emotion regulation strategies contributing to resilience in patients with depression and/or anxiety disorders. METHODS A total of 230 outpatients with depression and anxiety disorders were consecutively recruited and completed the Cognitive Emotion Regulation Questionnaire, the Connor-Davidson Resilience Scale, the Beck Depression Inventory, and the State Anxiety Inventory. A linear regression model was used to determine which cognitive emotion regulation strategies predicted resilience after controlling for relevant covariates. Additionally, this model of resilience was compared with those of depression and anxiety symptoms. RESULTS Adaptive strategies were more strongly correlated with resilience than maladaptive strategies. In the regression model, more use of refocus on planning and positive reappraisal as well as less use of rumination predicted high resilience after controlling for age, gender, marital status, depression, and anxiety. Among these strategies, refocus on planning was the common strategy contributing to resilience and depression. CONCLUSION These results suggested that the cognitive emotion regulation strategies of refocus on planning, positive reappraisal, and less rumination contribute to resilience in patients with depression and anxiety disorders. It might provide potential targets for psychotherapeutic intervention to improve resilience in these patients.

Low trait anxiety, high resilience, and their interaction as possible predictors for treatment response in patients with depression.

BACKGROUND Although many demographic and clinical characteristics have been suggested to predict treatment outcome of depression, they provide only a weak prediction for clinical response. Based on the predictive values of trauma and biological markers involved in stress response, we investigated the roles of baseline trait anxiety and resilience, which were assumed as vulnerability and resilience factors, respectively, in predicting treatment response in naturalistically treated outpatients with depressive disorders. METHODS A total of 178 outpatients with depressive disorders were consecutively recruited and completed measures of trauma experiences, psychological symptoms, and resilience at baseline. Response was defined by Clinical Global Impression (CGI)-Improvement score ≤2 at last visit during a 6month-treatment period. Univariate analyses and multiple logistic regression analysis were performed to determine predictors of treatment response. RESULTS Among demographic and clinical variables, treatment response was associated with increased age, longer treatment duration, higher resilience, and lower trait anxiety. In logistic regression analysis, resilience, trait anxiety, and their interaction significantly predicted treatment response after adjusting for age and treatment duration. Interaction between resilience and trait anxiety remained significant in the final model. Examining the interaction between the two, patients with low trait anxiety were only significantly affected by the level of resilience in response rate. CONCLUSIONS Low trait anxiety, high resilience, and their interaction might contribute to better treatment response in depressed patients. Our result suggested that individual differences in responding to stress might be important in predicting treatment outcome of depression in addition to other demographic and clinical factors.

Characteristics associated with low resilience in patients with depression and/or anxiety disorders

PurposeDespite a growing body of research on resilience and its clinical significance in depression and anxiety disorders, relatively little is known about contributing factors for resilience in patients with these illnesses. We aimed to find characteristics of patients having low resilience for elucidating its clinical implications in depression and/or anxiety disorders, primarily focused on potentially modifiable variables.MethodsA total of 121 outpatients diagnosed with depression and/or anxiety disorders completed questionnaires measuring socio-demographic, clinical, and positive psychological factors. We divided patients into the three groups based on their Connor–Davidson resilience scale scores and investigated predictors of the low- and medium- versus high-resilience groups using multinomial logistic regression analysis.ResultsIn the final regression model, low spirituality was revealed as a leading predictor of lower-resilience groups. Additionally, low purpose in life and less frequent exercise were associated with the low- and medium-resilience groups, respectively. Severe trait anxiety characterized the low- and medium-resilience groups, although it was not included in the final model.ConclusionsSpirituality, purpose in life, and trait anxiety contribute to different levels of resilience in patients with depression and/or anxiety disorders. Our results would deepen the understanding of resilience and provide potential targets of resilience-focused intervention in these patients.

The Korean Version of the Connor–Davidson Resilience Scale: An Extended Validation

The Connor-Davidson Resilience Scale (CD-RISC) is a brief self-rating questionnaire for measuring resilience. The aims of the present study were to describe the development of a Korean version of the CD-RISC (K-CD-RISC) and to more firmly establish its psychometric properties in terms of reliability and validity. The participants consisted of a general population sample (n=194) and psychiatric outpatients (n=127) with non-psychotic mood or anxiety disorders. The K-CD-RISC score means (standard deviation) were 65.9 (13.6) in the general population and 50.4 (20.5) in the psychiatric outpatients. The mean score of the general population was significantly higher than that of the psychiatric outpatients. Exploratory factor analysis revealed five factors, and the obtained factor structure was verified through confirmatory factor analysis. In the general population, the Cronbachs α coefficient of the K-CD-RISC was found to be 0.92. Greater resilience was found to be associated with less perceived stress, anxiety and depression and with higher levels of positive affect and purpose in life. Taken together, our findings suggest that the K-CD-RISC has good psychometric properties and is a valid and reliable tool for assessing resilience.

The moderation of resilience on the negative effect of pain on depression and post-traumatic growth in individuals with spinal cord injury

Abstract Purpose: To determine the moderating effect of resilience on the negative effects of chronic pain on depression and post-traumatic growth. Method: Community-dwelling individuals with SCI (n = 37) were recruited at short-term admission for yearly regular health examination. Participants completed self-rating standardized questionnaires measuring pain, resilience, depression and post-traumatic growth. Hierarchical linear regression analysis was performed to identify the moderating effect of resilience on the relationships of pain with depression and post-traumatic growth after controlling for relevant covariates. Results: In the regression model of depression, the effect of pain severity on depression was decreased (β was changed from 0.47 to 0.33) after entering resilience into the model. In the final model, both pain and resilience were significant independent predictors for depression (β = 0.33, p = 0.038 and β = −0.47, p = 0.012, respectively). In the regression model of post-traumatic growth, the effect of pain severity became insignificant after entering resilience into the model. In the final model, resilience was a significant predictor (β = 0.51, p = 0.016). Conclusions: Resilience potentially mitigated the negative effects of pain. Moreover, it independently contributed to reduced depression and greater post-traumatic growth. Our findings suggest that resilience might provide a potential target for intervention in SCI individuals. Implications for Rehabilitation The majority of individuals with spinal cord injury suffer from pain that is usually refractory to treatment. In a study among community-dwelling individuals with spinal cord injury, resilience mitigated the negative effects of pain on depression and post-traumatic growth. Resilience might be suggested to provide a potential target for intervention in individuals with spinal cord injury.

Resilience moderates the risk of depression and anxiety symptoms on suicidal ideation in patients with depression and/or anxiety disorders

BACKGROUND Few studies have investigated the role of protective factors for suicidal ideation, which include resilience and social support among psychiatric patients with depression and/or anxiety disorders who are at increased risk of suicide. METHODS Demographic data, history of childhood maltreatment, and levels of depression, anxiety, problematic alcohol use, resilience, perceived social support, and current suicidal ideation were collected from a total of 436 patients diagnosed with depression and/or anxiety disorders. Hierarchical multiple logistic regression analyses were used to identify the independent and interaction effects of potentially influencing factors. RESULTS Moderate-severe suicidal ideation was reported in 24.5% of our sample. After controlling for relevant covariates, history of emotional neglect and sexual abuse, low resilience, and high depression and anxiety symptoms were sequentially included in the model. In the final model, high depression (adjusted odds ratio (OR)=9.33, confidence interval (CI) 3.99-21.77) and anxiety (adjusted OR=2.62, CI=1.24-5.53) were independently associated with moderate-severe suicidal ideation among risk factors whereas resilience was not. In the multiple logistic regression model that examined interaction effects between risk and protective factors, the interactions between resilience and depression (p<.001) and between resilience and anxiety were significant (p=.021). A higher level of resilience was protective against moderate-severe suicide ideation among those with higher levels of depression or anxiety symptoms. CONCLUSIONS Our results indicate that resilience potentially moderates the risk of depression and anxiety symptoms on suicidal ideation in patients with depression and/or anxiety disorders. Assessment of resilience and intervention focused on resilience enhancement is suggested for suicide prevention.

Resilience as a Possible Predictor for Psychological Distress in Chronic Spinal Cord Injured Patients Living in the Community

Objective To investigate whether higher resilience level predicts low levels of psychological distress in chronic SCI patients living in the community. Method Thirty seven patients (mean age 41.5±10.9, male : female=28 : 9) with chronic spinal cord injury (duration 8.35±7.0 years) living in the community are included, who were hospitalized for annual checkups from November, 2010 to May, 2011. First, their spinal cord injury level, completeness and complications were evaluated. The patients completed questionnaires about their educational status, religion, employment status, marital status, medical and psychological history and also the following questionnaires: Hospital Anxiety and Depression Scale (HADS), Connor-Davidson Resilience Scale (CD-RISC), Alcohol Use Disorders Identification Test-alcohol consumption questions (AUDIT-C) and Health-related quality of life (EQ-5D). The patients were divided into two subgroups: patients with HADS ≥13 are classified as high psychological distress group and others as low psychological distress group. We compared the two groups to find statistically significant differences among the variables. Results CD-RISC, EQ-5D and employment status are significantly different between two groups (p<0.05). In a forward stepwise regression, we found that EQ-5D had a greater contribution than CD-RISC to the psychological distress level. Conclusion In addition to health-related quality of life, resilience can be suggested as a possible predictor of psychological distress in chronic SCI patients.

Prevalence and associated clinical characteristics of hepatitis B, C, and HIV infections among injecting drug users in Korea

Injecting drug use is associated with an increased risk of blood‐borne viral infections, such as hepatitis B and C viruses (HBV and HCV, respectively) and human immunodeficiency virus (HIV). However, their prevalence, virological characteristics, and associated factors are not clear among the injecting drug users in Korea. The aim of this study was to determine the prevalence of HBV, HCV, and HIV infection, as well as their virological and clinical characteristics of injecting drug users in South Korea. Between 2007 and 2010, 318 injecting drug users (89.3% male; mean ± age 41.9 ± 8.15 years) were participated. While HIV infection was not found, the seroprevalence of anti‐HCV and HBV surface antigen (HBsAg) was 48.4% (n = 154) and 6.6% (n = 21), respectively. HBV/HCV co‐infection was found in 4.1% (n = 13). Occult HBV infection was suggested in 5.0% (n = 16). Among the HCV genotypes, 1b (37.7%) and 2a/2c (35.7%) were mostly often detected. HCV RNA was detected in 98.1% (n = 151/154) and high‐level viremia (HCV RNA level, ≥400,000 IU/ml) were observed in 59.6% (n = 90/151). In multiple logistic regression analysis, old age (OR 1.18 per year, 95% CI = 1.09–1.27) and ever‐sharing injecting equipment (OR 4.17, 95% CI = 1.39–12.45) independently predicted HCV mono‐infection. The prevalence of HBV and HCV infection were high but largely undiagnosed in the present sample of Korean injecting drug users. Strategic prevention, screening, and treatment are needed to reduce further transmission and morbidity. J. Med. Virol. 85:575–582, 2013.

Differences of psychological effects between meditative and athletic walking in a forest and gymnasium

Abstract Several studies have reported that exercise and meditative activities in a forest are more effective than the same activities performed in an urban area. However, few studies have compared the direct effects of exercise to those of meditative activity in a forest and indoors. This study aimed to identify how the effects of the same activity might differ when performed in a forest as opposed to indoors, as well as how the effects of meditative and athletic activities in the same environment might differ. We recruited 139 females between 18 and 25 years of age and distributed the subjects into four groups by random allocation: athletic walking in the gymnasium (AG), athletic walking in the forest (AF), meditative walking in the gymnasium (MG), and meditative walking in the forest (MF). We evaluated the subjects before and after walking, using the State-Trait Anxiety Inventory-X, Rosenberg Self-Esteem Scale, and Happiness Index for Koreans. Meditative walking had greater effectiveness on the psychological aspects than athletic walking did in the same environment. Also, walking in the forest increased happiness to a greater degree than walking in the gymnasium at the same pace. Especially meditative walking in the forest was the most effective at increasing happiness.
