Initial Psychometric Properties of the Korean Altman Self-Rating Mania Scale: Preliminary Validation Study in a Non-Clinical Sample.

Objective: We aimed to examine the reliability and validity of the Korean Altman Self-Rating Mania Scale (K-ASRM) in a large sample of Korean non-clinical undergraduates.

Methods: Participants (n=1,091) filled out the K-ASRM with other self-report questionnaires assessing bipolarity, mood symptoms and affect. Reliability test, exploratory factor analysis and correlation analyses were conducted to examine its psychometric properties.

The link between hypomania risk and creativity: The role of heightened behavioral activation system (BAS) sensitivity.

Background: The relationship between bipolar disorder (BD) and creativity is well-known; however, relatively little is known about its potential mechanism. We investigated whether heightened behavioral activation system (BAS) sensitivity may mediate such relationship.

Methods: Korean young adults (N=543) completed self-report questionnaires that included the Hypomanic Personality Scale (HPS), the Behavioral Activation System(BAS) Scale, the Everyday Creativity Scale (ECS), the Positive Affect and Negative Affect Schedule (PANAS), and the Altman Self-Rating Mania Scale (ASRM).

Testing an affective judgment model of distress tolerance in college heavy drinkers.

Introduction: The objective of this study was to examine the relation between affects linked to avoidance/withstanding options and distress tolerance in heavy drinkers. It has been suggested that the expected rewards of taking withstanding options and the expected punishments of taking avoidance options could have an influence on judgment regarding withstanding ongoing distress. However, there are no studies that have tested this hypothesis.

Psychometric Properties of a Short Korean Version of the Revised Obsessive Intrusion Inventory.

Objective: The Revised Obsessive Intrusion Inventory (ROII) is a 52-item scale that evaluates obsessional intrusive thoughts. The aim of the present study was to validate a short, 20-item Korean version of the ROII (ROII-20).

Methods: Of the 1125 participants who completed the ROII-20, 895 participants completed the scale to examine the factor structure of the scale.

The Obsessive-Compulsive Inventory-Revised (OCI-R): psychometric properties of the Korean version and the order, gender, and cultural effects.

In this study, the psychometric properties of the Korean version of the OCI-R and the effects of order, gender, and culture on the inventory were examined in a nonclinical and in a clinical sample comprised of 702 college students and 91 patients with OCD. As a result, the original six-factor model is supported by the confirmatory factor analysis. The internal consistency, test-retest reliability, and the convergent and divergent validity of the OCI-R total and its subscales were good.

The Penn State Worry Questionnaire: psychometric properties of the Korean version.

The factor structure and concurrent validity of the Penn State Worry Questionnaire (PSWQ) were examined in two college student samples in Korea. We demonstrated method effects due to the inclusion of negatively keyed items. Confirmatory factor analyses supported the single-factor model with method factor.

Evaluation of the integrated cognitive model of depression and its specificity in a migrant population.

This study empirically tested the specificity of the integrated cognitive model (ICM) of depression, which postulates that negative life events interact with dysfunctional attitudes to increase the frequency and severity of automatic thoughts, subsequently affecting depressive symptoms. We also examined the three competing models: the linear mediation model, the alternative etiologies model, and the symptom model. We anticipated that we might examine these models more appropriately using data from a population at an increased risk of developing depressive symptoms.

Factor structure and internal consistency of the Young Schema Questionnaire (Short Form) in Korean and Australian samples.

We investigated cross-cultural differences in the factor structure and psychometric properties of the 75-item Young Schema Questionnaire-Short Form (YSQ-SF). Participants were 833 South Korean and 271 Australian undergraduate students. The South Korean sample was randomly divided into two sub-samples.

Testing the autogenous-reactive model of obsessions.

Two independent studies were conducted to examine the autogenous-reactive subtype model of obsessions [Lee and Kwon, 2003]. Study 1 demonstrated that 30 obsessive-compulsive (OCD) patients' responses to autogenous versus reactive obsessions differed significantly with respect to emotional reactions, cognitive appraisals, and control strategies. Study 2 compared OCD patients whose primary obsessions were of the autogenous subtype (n=13) with OCD patients whose primary obsessions were of the reactive subtype (n=14).

A comparison of autogenous/reactive obsessions and worry in a nonclinical population: a test of the continuum hypothesis.

Employing the autogenous-reactive model of obsessions (Behaviour Research and Therapy 41 (2003) 11-29), this study sought to test a hypothesized continuum where reactive obsessions fall in between autogenous obsessions and worry with respect to several thought characteristics concerning content appraisal, perceived form, and thought triggers. Nonclinical undergraduate students (n=435) were administered an online packet of questionnaires designed to examine the three different types of thoughts. Main data analyses included only those displaying moderate levels of obsessions or worries (n=252).

Thought disorder in patients with obsessive-compulsive disorder.

We examined the presence of disordered thinking/perception in patients with obsessive-compulsive disorder (OCD). Recently, an obsession model has been proposed, which classifies obsessions into two different subtypes: autogenous obsessions and reactive obsessions (Lee & Kwon, 2003). Based on this model, we hypothesized that OCD patients primarily displaying autogenous obsessions as opposed to reactive obsessions would display more severely disordered thinking/perception.

Cognitive change processes in a group cognitive behavior therapy of depression.

The present study attempted to examine the causal relationships among changes in automatic thoughts, dysfunctional attitudes, and depressive symptoms in a 12-week group cognitive behavior therapy (GCBT) program for depression. In all, 35 depressed patients attending the GCBT program were monitored with the Automatic Thoughts Questionnaire, Dysfunctional Attitudes Scale, and Beck Depression Inventory at the pre-treatment, 4th and 8th sessions, and post-treatment. The results were as follows: (1).
