A dance exercise program was performed to investigate the effects of exercise on exercise intention and exercise-related affect as these are important determinants of exercise behavior.

The subjects were overweight (23≤or=BMI≤or=25) or obese (BMI≥or=25) postmenopausal women (n=14), who participated in an exercise program from May, 2003 through November, 2003 at one public health center located in Kyong-gi Province. Data was analyzed with an SAS PC program.

Exercise intention was significantly increased after the exercise program (t=-2.24, P=0.04). Exercise-related affect was also increased, but there was no statistically significant change (t=1.81, P=0.09).

This study suggests that exercise participation can increase the level of future exercise behavior by increasing exercise intention and exercise-related affect.

Recently, the interest in positive psychotherapy is growing, which can help to encourage positive relationships and develop strengths of people. This study was conducted to investigate the effects of a positive psychotherapy program on positive affect, interpersonal relations, resilience, and mental health recovery in community-dwelling people with schizophrenia.

The research was conducted using a randomized control group pretest-posttest design. A total of 57 adults with schizophrenia participated in this study. The study participants in experimental group received a positive psychotherapy program (n=28) and the participants in control group received only the usual treatment in community centers (n=29). The positive psychotherapy program was provided for 5 weeks (of 10 sessions, held twice/week, for 60 minutes). The study outcomes included positive affect, interpersonal relations, resilience, and mental health recovery. The collected data were analyzed using repeated measures ANOVA for examining study hypothesis.

Results showed that interpersonal relations (F=11.83, p=.001) and resilience (F=9.62, p=.003) significantly increased in the experimental group compared to the control group. Although experimental group showed a slight increase in positive affect, it was not significant.

The study findings confirm that the positive psychotherapy program is effective for improving interpersonal relations and resilience of community-dwelling people with schizophrenia. Based on the findings, we believe that the positive psychotherapy program would be acceptable and helpful to improve recovery of mental health in schizophrenia.

The purpose of the study was to investigate the relationships between the Myers-Briggs Type Indicator (MBTI) psychological type and marital satisfaction, divorce proneness, positive affect, and conflict regulation in couple visiting a clinic.

Couples (n=62) who visited "M" couple clinic participated in the study. Data were collected from March to June 2009 using the Marital Satisfaction Scale, Marital Status Inventory, Positive Affect Inventory, and Conflict Regulation Inventory.

The couples showed no significant differences in marital satisfaction, positive affect, and conflict regulation according to similarities between spouses in MBTI types. However, they showed significant differences in divorce proneness of husband according to a similarity in the Sensing/Intuition indicator. They also showed significant differences in divorce proneness, positive affect, and conflict regulation between the couples for ISTJ (Introversion, Sensing, Thinking, Judging) or ESTJ (Extraversion, Sensing, Thinking, Judging) types compared to other couples.

When nurses counsel couples, they should understand that differences in psychological type between spouses affects their marital relationship. In addition, nurses should educate couples on the characteristics of each type according to the couple's types and help them to understand each other, especially for couples where one spouse is the ISTJ/ESTJ type. These interventions will improve marital satisfaction and prevent the divorce in these couples.

The purpose of this study was to identify the factors that predict discomfort after coronary angiography or percutaneous coronary intervention (PCI) among hospitalized patients.

A total of 203 patients who underwent coronary angiography or PCI were recruited from C hospital located in S city, J province, from June through August 2008. The level of discomfort was measured and standardized by two instruments, discomfort questionnaire and the Visual Analogue Scale (VAS).

Stepwise multiple regression showed that the factors predicting the level of discomfort were type of angiography, gender, previous angiography, dysuria, pre-information, and sleep satisfaction, which together explained 30.6% of the total variance of the level of discomfort.

Patients who had previous experience with these procedures, received a pre-information about the upcoming procedure, had no dysuria, and had slept well after the procedure were less likely to complain discomfort. Pre-informed education should be given by nurses to patients who will have an angiography or PCI to reduce their physical and emotional discomforts.

The purpose of this study was to identify factors related to nurses' organizational citizenship behavior using multilevel analysis which included both nurse characteristics at individual levels and nursing unit characteristics at group levels.

The sample was composed of 1,996 nurses who were selected from 182 nursing units in 28 hospitals in six metropolitan cities and seven provinces using cluster sampling. Data were collected using self-reported questionnaires from February to March 2006.

The results of the study indicated that individual level variables related to organizational citizenship behavior were religion, job position, clinical career, self efficacy, positive affectivity, and supervisor support. The group level variables related to organizational citizenship behavior were collective efficacy, number of nurses in a nursing unit, and the average salary level of a nursing unit. 30.9% of individual level variances of organizational citizenship behavior were explained by the nurses' individual level variables. The explanatory power of group level variables, which is related to group level variances of organizational citizenship behavior, was 75.5%.

This research showed that it was necessary to develop appropriate strategies related to not only individual factors, but also higher-level organizational factors such as collective efficacy, to improve individual performances in the hospital.

This paper reports a randomized controlled trial to investigate the effects of a Marital-relationship enhancement program(MREP) for marital couples.

Volunteer couples from several well-being centers in Seoul were randomly assigned either to a treatment group (n=36), participating in a MREP based on Gottman's “sound marital house” theory, or to a control group (n=35) receiving no treatment. The content of the MREP was provided to the control group after the research was completed. Data was collected from December 2003 to May 2004 using modified versions of the inventories developed by Gottman on marital satisfaction, positive affect, conflict regulation, and communication barriers.

Participants in the experimental group showed significant improvements in marital satisfaction, positive affects, conflict regulation, and communication-barrier scores compared to the control group.

The present program for marital-relationship enhancement is helpful in enhancing marital relationships and regulating conflict between marital couples and, ultimately, may be useful to prevent divorce.
