  • Objectives The purpose of this study was to examine the differences according to depressive symptom-related difficulty status. Methods 2828 participants were a divided into depressive symptom-related difficulty group (difficult group, n = 774), and a non-depressive symptom-related difficulty group (not difficult group, n = 2054). The psychological character of the participants were assessed using the Korean version of the Patient Health Questionnaire-9 (PHQ-9), Satisfaction with Life Scale (SWLS), the 12-item General Health Questionnaire (GHQ-12), and Conner-Davidson Resilience Scale (CD-RISC). Statistical analyses were done using t-test, chi-square, and analysis of covariance (ANCOVA). Results Compared with the no difficulty group, the difficulty group reported significantly higher score in all items of PHQ-9. The score of "feeling tired" was the highest and the score of "suicidal ideation" is the lowest in both groups. ANCOVA analysis that is adjusted with the total score of PHQ-9 showed the differences in SWLS, GHQ-12, and CD-RISC scores between the difficulty group and the no difficulty group. Conclusions The findings suggest that there are different characters on PHQ-9, SWLS, GHQ-12, and CD-RISC according to depressive symptom-related difficulty. Therefore, it is required not only to evaluate depressive symptoms in patients with depression, but also the depressive symptom-related difficulty to understand these differences.

  • Purpose: This study was to test the effects of a full body massage on labor pain and delivery stress reaction for primipara during labor. Method: This study employed a quasi- experimental method(nonequivalent control group, pre-post test design). The subjects of this study were 57 primipara hospitalized at the U OB & GYN hospital in Inchon from November 1. 2001 to July 31, 2002. 28 women were assigned to the experimental group and 29 to the control group. The experimental group was given 20 minutes full body massage for each of three delivery phases. The control group was given conventional delivery care. The levels of labor pain were measured by the Visual Analogue Scale and the expression scores of the labor pain and the levels of delivery stress reaction were measured by pulse rate, respiration rate, and blood pressure, and State-Anxiety Scale. Data were analyzed using the repeated measures analysis of covariance(ANCOVA), t-test, $X^2$- test, simple ANCOVA with SPSS program. Result: There was no interaction effect between time and group(F=.370, p=.693), but significant time effects were found for subjective labor pain(F=3.840, p=.028). There was no interaction effect between time and group(F=.112, p=.894), but significant group effects were found for objective labor pain(F=12.299, p=.001). There was no interaction effect between time and group for PR(F=.172, p=.843), RR(F=.626, p=.539), SBP(F=.089, p=.915), DBP(F=.748, p=.479), but significant group effects were found for SBP(F=7.547, p=.008). The level of status anxiety of the experimental group was significantly lower than the control group(F=11.787, p=.001). Conclusion: This study showed that the full body massage has partially positive effect on labor pain and delivery stress reaction. Therefore this study suggested that the full body massage might be used clinically to help primipara during labor.

  • Objective : The aim of this study is to identify the relationship between childhood abuse and affective symptom including resilience in patients with depression or anxiety. Methods : A total 256 outpatients diagnosed with depressive disorder or anxiety disorder according to DSM IV-TR, were evaluated with Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Parent-Child Conflict Tactics Scale (PCCTS), Connor-Davidson Resilience Scale (CD-RISC). Independent t-test, Chi-square analysis and analysis of covariance (ANCOVA) were performed to identify the demographics of patients and the relationship between affective symptoms including resilience and childhood abuse. Results : Among demographic and clinical variables, patients with childhood abuse history were significantly higher rate in patients who were living alone and unemployed. In affective symptoms, patients with childhood abuse history were significant more severe in depressive symptoms, and state anxiety score than patients without history of childhood abuse. Patients with childhood abuse history had higher score for trait anxiety and lower score for resilience than patients who had no history of childhood abuse. Conclusion : These finding suggest that history of childhood abuse might be risk factor on depressive and anxiety symptoms severity. And this might be a predictable factor of poor treatment outcome.

  • Purpose: The aim of this study was to determine the effects of isokinetic eccentric training (IET) on lower extremity muscle activation and walking velocity according to slow velocity and fast velocity of isokinetic eccentric training in stroke patients. Methods: Thirty subjects were randomly divided into three groups: experimental group I (n=10), group II (n=10), and control group III (n=10). Each group was provided intervention under three conditions, as follows: isokinetic eccentric training + slow velocity (group I), isokinetic eccentric training + fast velocity (group II), and sit to stand training (group III). The training program was conducted for eight weeks (five times per week; 30 minutes per day). Subjects were measured on lower extremity muscle (vastus lateralis, vastus medialis, gastrocnemius) activation and walking velocity. Analysis of covariance (ANCOVA) were performed for comparison of lower extremity muscle activation and walking velocity between different intervention methods. Results: Significant difference in lower extremity muscle activation and walking velocity was observed in experimental group I and group II compared with the control group III (p<0.01). Results of post-hoc analysis showed a significant in lower extremity muscle activation and walking velocity in group I compared with group II and group III. Conclusion: Findings of this study suggest that slow velocity and fast velocity using isokinetic eccentric training may have a beneficial effect on improvement of lower extremity muscle activation and walking velocity in stroke patients.
