PURPOSE: The purpose of this study was to analyze the effects of respite care. The analysis was conducted by reviewing published intervention studies on the effects of formal respite care for caregivers of dementia patients, patients with dementia, and the prevented or delayed rate of institutionalization of the patients.
METHOD
Two computerized databases (MEDLINE, CINAHL) were searched to find respite care-related articles published from the year of 1981 to 2000. A total of 49 published articles were identified. Of them, nine studies, which met for the inclusion criteria of this study, were included.
RESULTS
Results revealed that there was little evidence of the effect of respite care on, not only caregivers' burden, stress, depression and well-being, but also the rate of institutionalization of the patients. It was noteworthy that dementia patients reported fewer problems in behavior, although cognitive functioning and activity of daily living abilities continued to decline. However, these findings should be carefully interpreted because of methodological problems, such as non-random sampling, non random group assignment, a small sample size, uncontrolled confounding variables, limited period of services, and no specific types of services.
CONCLUSION
It is recommended to conduct intervention studies of respite care being conducted in Korea with the corrections of methodological problems suggested from this study.
The theory of unpleasant symptoms is a middle-range theory proposed by Lenz and her colleagues (1997). Analysis and evaluation of this theory was performed using Fawcett (1999) and Fawcett and Downs's (1992) guidelines. Results of the theory analysis and evaluation suggest that the theory of unpleasant symptoms has theoretical and social significance and parsimony. However, a lack of internal consistency was evident. For empirical adequacy of the theory, it is recommended that research be conducted examining the complexities of the interaction effects, reciprocal relationships, and medication effects among physiological, psychologic, and situational factors, symptoms, and performance. The knowledge derived from the research findings should be used in practice for patients experiencing symptoms.
The purpose of the present study is 1) to explain major effect models (main, moderating, and mediating) of social support and statistical methods for testing the effect models and 2) to analyze and evaluate the consistency in the use of the effect models and its statistical methods in Korean nursing studies. A total of 57 studies were selected from Journal of Korean Academy of Nursing, Journal of Korean Academic Society of Adult Nursing, Journal of Korean Women's Health Nursing Academic Society, Journal of Fundamentals of Nursing, Journal of Korean Community Nursing, Journal of Korean Psychiatric and Mental Health Nursing Academic Society, and Journal of Korean Pediatric Nursing Academic Society published in the year of 1990-1999. In results, most studies on social support performed in Korea Nursing Society were about a main effect model. There are few studies on moderating or mediating model of social support. Thus, it was difficult to find research findings how, why, under what conditions social support impacted on health outcomes. Most studies on the moderating or mediating effect model of social support used statistical methods for testing main effect model rather than for testing moderating or mediating effect model. That is, there are inconsistency between effect models of social support and its statistical methods in Korean nursing researches. Therefore, it is recommended to perform studies on moderating or mediating effect model and use appropriate statistical methods.
The present study is a descriptive study to investigate nurses'perception of barriers to research utilization. A total of 274 participants in this study consisted of registered nurses working in a large, urban and academic medical center. A questionnaire packet containing the Barriers Scale, and a demographic profile was distributed to nurses and they were asked to return the packet to a return-box in the Nursing Office after completion. The greatest barrier was insufficient time on the job to implement new ideas. Next was `implications for practice are not made clear'. Also the item of the English language in research articles was considered to be the ninth barrier. The greatest mean score of each of the sub-scales was the communication factor. The were followed by the organization, research, and nurse factors. Compared with the means from other studies, the mean scores of the communication and research factors were higher in this study. Nurses who had not taken a class of research methods found the communication and research factors as a higher barrier than those who did. Also, nurses who did not participate in a conference last year perceived the research factor as higher than those who did. It is recommended that English and research classes should be strengthened in educational nursing programs. The researchers should also describe the section of implication for practice as more detail and clearer for the understanding of nurses; Lastly journals in a libraries or online journal systems should be easily accessible.
The purpose of the present study is to identify the mediation effect of hope between fatigue and psychosocial adjustment in women with breast cancer. The framework for this study was guided by concepts and propositions derived from the theoretical and empirical literature on fatigue, hope and adjustment. The design of this study is a descriptive correlation study using a cross-sectional design. One hundred and twenty two outpatients with early breast cancer, receiving post-surgical radiation therapy or chemotherapy, were selected from three major medical centers in Seoul, Korea. A packet including PABCF (Psychosoical Adjustment to Breast Cancer Factor), revised RPFS (Revised Piper Fatigue Scale), HHI (Herth Hope Index), and self-addressed return envelope was given to the participants at seven to eight weeks post surgery. The questionnaires were to be completed at home and returned to the researcher by mail. The obtained data were analyzed using three regression equations guided by Baron and Kenny (1986); first, hope was regressed on fatigue; second, psychosocial adjustment was regressed on fatigue; and third, psychosocial adjustment was regressed on fatigue and hope, simultaneously. In the first equation, fatigue explained 4% of the variance in hope. In the second equation, fatigue explained 47% of the variance in psychosocial adjustment. In the last equation, hope and fatigue significantly explained the variance in psychosocial adjustment. Therefore, all conditions for the test of mediation effect of hope were satisfied. For the test of the mediation effect, the beta coefficients of fatigue on psychosocial adjustment on the second and third regression equations were compared. The beta coefficients were decreased from .69 (p < .001) on the second regression equation to .63 (p < .001) on the third regression equation. Thus, the hypothesis of this study was supported. As a result of this study, the negative Influence of fatigue on psychosocial adjustment is dampened through the mediator effect of hope in women with breast cancer. Therefore, when planning care for the adverse effect of fatigue on psychosocial adjustment, oncology nurses should consider hope as a mediator between fatigue and psychosocial adjustment to breast cancer.
Most people experience fatigue at some point in their lives, and they say the word 'fatigue' in their ordinary conversational speech. The ordinary word is used as a military or engineering term and has been studied in various different disciplines such as ergonomics, physiology, psychology, medicine, and nursing. In spite of its widespread uses, however, fatigue has not been well defined. The terms of fatigue is thus often used with different meanings and is applied in diverse contests that had led to a confusion of ideas. In people with cancer, fatigue is reported as a major distress. Despite the importance of fatigue in cancer patients, the phenomena of fatigue is poorly understood. Therefore, the purpose of the present study is to analyze the concept of fatigue in people with cancer. The process for the concept analysis was guided by Walker and Avant's conceptual analysis methodology. The identified attributes of fatigue in the present study were subjective feeling, lack of energy, sustenance, and multi-dimensions. The antecedents were cancer treatment and economic status. The consequences were decreased daily, vocational, leisure, and social activities, uncertainty, and difficulties in adjustment. Symptoms(pain, anorexia, and insomnia) and emotional disturbance were not clear whether they are antecedents or consequences. However, they are related with cancer related fatigue. Even though still in the beginning stage, instruments measuring cancer related fatigue have been developed by some nursing investigators.
This study was done to identify the prevalence of benign prostatic hyperplasia (BPH) and BPHrelated symptoms among community-dwelling elderly men in Korea. In addition, quality of life and health care-seeking behavior were explored.
A total of 417 elderly men were surveyed using the IPSS (International Prostatic Symptom Score) and a structured questionnaire on health care-seeking behaviors.
The prevalence of BPH was 19.7%. Of those with BPH, 80.3% reported mild symptoms, 13.2% moderate symptoms, and 6.5% severe symptoms. The severity of BPH-related symptoms was significantly correlated with quality of life. Among those with BPH, 42.7% had never consulted with anyone about their symptoms.
BPH has emerged as a serious public health problem in elderly men. Elderly people who experience worse symptoms of BPH have a lower quality of life. Many elderly with BPH do not seek health care, mainly due to misconceptions about BPH. The provision of educational programs for BPH may significantly improve the quality of life of elderly men.
The purpose of this study was to identify direct, mediating, and moderating relationships of mood disturbance, symptom experience, and attentional function in Korean women with breast cancer based upon a middle-range theory of unpleasant symptoms.
This study used a cross-sectional, correlational design. A convenience sample of 125 women receiving chemotherapy for breast cancer was recruited from a university hospital in South Korea. The women completed questionnaires on mood disturbance, symptom experience, and attentional function using the Linear Analogue Self-Assessment Scale, the Symptom Experience Scale, and the Attentional Function Index, respectively.
Each mood disturbance and symptom experience showed a significant relationship with attentional function. Symptom experience did not act as a mediator between mood disturbance and attentional function, but it did act as a moderator: patients with a higher level of mood disturbance exhibited a lower level of attentional function when their symptoms were at the level of medium, but not when their symptoms were either high or low.
This suggests that clinical interventions for attenuating the influence of mood disturbance on attentional function may be effective only in women experiencing medium level of symptoms.
The purpose of this study was to validate Quality of Life Index-Cancer (Q.L.I.-C) developed by Ferrans (1990) among Korean cancer patients.
This study design was exploratory factor analysis methodology. Q.L.I.-C was translated into Korean and reverse-translated into English. The subjects were 357 Korean patients with various cancers. Data were collected by questionnaires from May to August, 2000 and was analyzed by descriptive statistics, Principal Component Analysis for construct validity and Cronbach's alpha coefficient for reliability.
The range of factor loadings was .446~.841. The explained variance from the 5 extracted factors was 63.7% of the total variance. The first factor ‘family’ was 35.5%, and ‘health & physical functioning’, ‘psychological’, ‘spiritual’, and ‘economic’ factors were 11.5%, 6.9%, 5.6%, and 4.2% respectively. Because of cultural difference between Americans and Koreans, certain items such as sexuality, job status, and education were deleted from the extraction of factors in this study. The Cronbach's alpha coefficient was .9253 among the 28 items.
Q.L.I.-C could be applied in measuring quality of life of Korean cancer patients. It also recommend to do further studiesfor validation of Q.L.I.-C American and Korean versions relating to cultural differences.
The prevalence of urinary incontinence (UI) among community-dwelling older women in Korea is not well known. This study examined the prevalence of UI and UI-related knowledge among community-dwelling Korean women aged 55 and over.
A cross-sectional descriptive-correlational study was conducted. Data were collected from 276 women aged 55 and over in a metropolitan city using a structured questionnaire.
Of 276 respondents, 28.3% (n=78) reported experiencing UI. More than 50% of respondents incorrectly agreed with the statement that UI is the result of normal aging, with only 20.9% realizing that there is an exercise that can control urine leaks when one coughs, sneezes, or laughs. Older women who had sought treatment had higher mean score for UI-related knowledge.
This study revealed substantial misconception about UI among community dwelling older women, demonstrating that comprehensive educational programs need to be developed to increase knowledge of UI.
This cross-sectional survey was undertaken to examine the differences of BSE (breast-self examination) performance and health beliefs between Korean and Korean-American women and to identify which factors influence the BSE based on the HBM variables.
The study subjects were recruited from both Korea(189 women) and Cleveland in Ohio, USA(146 women). The HBM variables were measured using a reliable and valid Health Belief Model Scale. The subjects were also asked whether or not they did a BSE in the last year.
The Korean-American women who performed the BSE was statistically higher than that of Korean women. Regarding to the BSE-related health belief, the scores of benefits, confidence, and health motivation was significantly higher in Korean-American. After controlling for living places, age, education, and job, barriers and confidence variables significantly explained the BSE performance of Korean and Korean-American women.
There was a differences in BSE-related health belief and performance between Korean and Korean-American women. Among health belief variables, barriers and confidence were core variables predicting the BSE performance of Korean and Korean-American women together.
The purpose of this study was to identify trends for studies published in the Journal of Korean Academy of Nursing and journals published by member societies from inaugural issues to 2010.
A total of 6890 studies were analyzed using descriptive statistics.
Quantitative studies accounted for 83.6% while qualitative studies accounted for 14.4%. Most frequently used research designs were quasi-experimental (91.1%) for experimental research and survey (85.2%) for non-experimental research. Most frequent study participants were healthy people (35.8%), most frequent nursing interventions, nursing skills (53.5%), and 39.8% used knowledge, attitude and behavior outcomes for dependent variables. Most frequently used keyword was elderly. Survey studies decreased from 1991 to 2010 by approximately 50%, while qualitative studies increased by about 20%. True experimental research (1.2%) showed no significant changes. Studies focusing on healthy populations increased from 2001-2005 (37.5%) to 2006-2010 (41.0%). From 1970 to 2010, studies using questionnaire accounted for over 50% whereas physiological measurement, approximately 5% only. Experimental studies using nursing skill interventions increased from 1970-1980 (30.4%) to 2006-2010 (64.0%). No significant changes were noted in studies using knowledge, attitude and behavior (39.9% ) as dependent variables.
The results suggest that further expansion of true experimental, qualitative studies and physiological measurements are needed.
The purpose of this study was to develop and evaluate a quality of life scale for Korean patients with cancer (C-QOL).
The C-QOL was developed and validated as follows; item generation, pilot study, and psychometric tests. A total of 337 patients diagnosed with stomach, liver, lung, colon, breast, or cervix cancer were recruited. The patients were asked to complete the preliminary questionnaire comprising the content-validated items, the SF-36, and the ECOG performance status. The obtained data was analyzed using descriptive statistics, factor analysis, multidimensional scaling (MDS), multitrait/multi-item matrix, ANOVA, t-test, and Cronbach's alpha.
Preliminarily twenty-six items were generated through content validity and a pilot study. Factor analysis and MDS extracted a total of 21 items with a 5-point Likert-type scale (C-QOL). The C-QOL included five subscales: physical status (6 items), emotional status (6 items), social function (3 items), concern status (2 items), and coping function (4 items). The C-QOL established content validity, construct validity, item convergent and discriminant validity, known-groups validity, reliability, and sensitivity.
The Newly developed C-QOL is an easily applicable instrument which established psychometric properties and reflected Korean culture. It is recommended for further study to examine the responsiveness of the C-QOL using a longitudinal research design.
Health-related quality of life (HRQOL) in patients with cardiovascular disease in Korea has rarely been studied, mostly due to the lack of a psychometrically validated disease-specific instrument. The purpose of this study was to develop and validate a cardiovascular specific-HRQOL questionnaire (CD-QOL).
The CD-QOL was developed and validated as follows; item generation, pilot study, and psychometric tests. Patients were recruited from three-university hospitals. The patients were asked to complete the preliminary questionnaire comprising the content-validated items, SF-36, and CES-D. The NYHA and KASI classifications were used to classify the functional performance of the patients. The data was analyzed using correlation, factor analysis, multidimensional scaling, multitrait/multi-item matrix, ANOVA, and Cronbach's alpha.
Preliminarily, thirty-nine items were generated. Factor analysisextracted a five-factor solution with a total of twenty-two items. One item was deleted based upon the MDS. The remaining items were moderately correlated with the subscales of the SF-36 and associated with depression measured with the CES-D. The mean scores of patients in NYHA and KASI class I were significantly higher than those in NYHA and KASI class II or/and III, which suggested patients with better functional performance were likely to have a better HRQOL. Cronbach's alphas of the total and subscales were all greater than 0.70.
The CD-QOL is a easily applicable instrument with excellent psychometric properties of content, criterion, factorial, convergent, and known-groups validity, and internal consistency reliability in Korean patients with cardiovascular disease.
