    ABSTRACT: PurposeTo examine the potential value of a creative art-based activity as a caring modality for promoting holistic well-being among chronic stroke patients, and to explore the feelings and meanings that stroke patients derived from their experience in leisure art-based creative engagement (LACE).DesignQualitative design.Method Participants were recruited through purposive and snowball sampling. Individual semi-structured interviews were conducted. Qualitative content analysis was performed. The design and implementation of LACE was guided by Watson's theory of caring.FindingsTwenty-four participants completed the study. Four themes emerged from participants' account of experiences with the LACE: (1) appreciation of opportunities, (2) appreciation of self, (3) appreciation of others, and (4) appreciation of life.Conclusion From the perspective of the participants, engaging in LACE enhances their sense of enjoyment and self-expression. Furthermore, they perceived LACE as an affirmation of life and an empowering process strengthening their connection and appreciation with the self and others.Clinical RelevanceThis study adds evidence to existing literature on Watson's theory-guided design and implementation of caring initiatives for community rehabilitation and has laid the groundwork for developing further evidence-based research in leisure art-based caring occasions for promoting holistic well-being in stroke rehabilitation.

    ABSTRACT: AimTo examine the effects of a transtheoretical model–based exercise stage–matched intervention on exercise behaviour and quality of life in patients with coronary heart disease.Background Exercise-based cardiac rehabilitation has been shown to be beneficial to quality of life for patients with coronary heart disease. However, patients' participation in rehabilitation programmes is poor. The transtheoretical model has been found to be an effective model for changing exercise behaviour in various populations; however, few studies have examined its effects on patients with coronary heart disease.DesignRandomized controlled trial.MethodsA total of 196 eligible patients were recruited from September 2009–January 2011 and randomly allocated to the control, ‘sham’ or experimental group. Outcome measures including exercise behaviour and quality of life were assessed at baseline, immediate postintervention and at 3- and 6-month follow-ups. The chi-square test and Kruskal–Wallis test were used to analyse data.ResultsFindings showed that, compared with the other two groups, patients in the Experimental group were more likely to be at the action and maintenance stages according to the exercise stages of change scale. They also showed longer moderate-intensity exercise duration as recorded by a logbook and significantly greater improvements in physical functioning, general health, vitality, social functioning, mental health, physical component summary and mental component summary of SF-36 after the 8-week intervention and up to 3- and 6-month follow-ups.Conclusion The transtheoretical model–based exercise stage–matched intervention has positive effects on exercise behaviour and quality of life in patients with coronary heart disease.

    ABSTRACT: Angina is one of the most common complaints among patients with coronary heart disease (CHD). Evidence has shown that regular exercise is beneficial for angina management. However, poor adherence to exercise prescription may limit its effect on angina symptoms and rehabilitation outcomes. The transtheoretical model (TTM) is an effective model for changing exercise behavior in various populations. However, few studies have examined its effects on changing exercise behavior and angina in patients with CHD. This study aimed to examine the effects of a TTM-based stage-matched exercise intervention (SMEI) on exercise behavior and angina in sedentary patients with CHD. A randomized controlled trial with repeated-measures design was adopted. A total of 196 patients were recruited and randomly assigned into a conventional group, a patient education group, or an SMEI group, with stratification of their exercise stages of change. Outcome measures included exercise behavior and angina at baseline, immediately after intervention, and at 3- and 6-month follow-up. Our findings showed that the SMEI group demonstrated more positive shifts in exercise stages of change (P < 0.01) and better improvement in physical limitation (P < 0.01), treatment satisfaction (P < 0.01), and disease perception (P < 0.01) measured by the Seattle Angina Questionnaire than the other 2 groups up to 6-month follow-up periods. No significant differences were found among the 3 groups at each time point in angina stability and angina frequency measured by the Seattle Angina Questionnaire and in the frequency, severity, and duration of anginal attacks according to a logbook kept by the participants. The TTM-based SMEI has positive effects on patients' exercise behavior and partially positive effects on their angina.

    ABSTRACT: AimTo explore factors associated with health-related quality of life of patients with implantable cardioverter defibrillators.Background Substantial evidence indicates that implantable cardioverter defibrillator is proven to increase survival rate by terminating life-threatening arrhythmia. However, this device can negatively affect health-related quality of life. Little is known about factors associated with health-related quality of life of patients with implantable cardioverter defibrillators, particularly in Asian population.DesignA transversal descriptive design was used.Methods Data were collected from a convenience sample of 139 adult patients with implantable cardioverter defibrillators from 4 January–30 April 2012 using the structured questionnaires administered by the researcher and medical record reviews. The Short Form-36 Health Survey version 2 was used to measure health-related quality of life.ResultsA total of 139 Chinese patients, including 107 (77·0%) males with a mean age of 63·0 (14·6) years, were selected. The physical component summary was relatively lower, whereas the mental component summary was relatively higher than that of the general Hong Kong Chinese population. Multivariable regression analysis revealed gender, self-care dependence, educational level, atrial fibrillation, diabetes mellitus, anxiety and depression significantly associated with physical or mental quality of life.Conclusions Depression was a common factor affecting physical and mental quality of life. Self-care dependence, atrial fibrillation, diabetes mellitus, depression and anxiety could be improved. Our findings expand existing knowledge on identifying at-risk patients for having lower quality of life, thus allowing development of appropriate interventions targeting risk factors for improving health-related quality of life of patients with implantable cardioverter defibrillator.

    ABSTRACT: Objective To determine whether a transtheoretical model-based exercise stage-matched intervention (ESMI) has positive effects on the exercise behavior of sedentary patients with coronary heart disease (CHD). Methods The study was a randomized controlled trial with a repeated measures design. Participants (N = 196) were randomly allocated to either a Conventional (C) group, a Patient Education (PE) group, or an ESMI group. Exercise behavior was measured by exercise stages of change, exercise self-efficacy, exercise decisional balance, and duration of moderate exercise at baseline, immediate post-intervention, and at 3- and 6-month follow-up. Results Our results showed that the ESMI group demonstrated a more positive shift in exercise stages of change (p < 0.01), higher exercise self-efficacy (p < 0.01), greater exercise benefits (p < 0.01), fewer exercise barriers (p < 0.01), and longer moderate exercise duration (minutes/week) (p < 0.01) after completion of the 8-week intervention compared with the C and PE groups. These significantly positive effects were maintained at 3- and 6-month follow-up. Conclusion The transtheoretical model-based ESMI had significantly positive effects on the exercise behavior of sedentary CHD patients. Practice implications It is important to provide a structured education program for CHD patients, preferably guided by the transtheoretical model.

    ABSTRACT: BACKGROUND: Social support has been identified as a significant factor positively influencing quality of life (QOL) in breast cancer survivors. However, less is known about whether and how social support remains important among cancer survivors over the course of the survivorship trajectory. AIM: To explore social support and its relationship with QOL in breast cancer survivors in China. METHODS: This was a sequential mixed methods study. In Phase I, 100 breast cancer survivors were surveyed using standardized questionnaires. A multivariate regression analysis was performed to examine the relationship between social support and QOL after controlling for annual household income and length of survivorship. In Phase II, individual in-depth interviews were conducted to understand social support experience from 29 survivors selected from Phase I. Interview data were transcribed and analyzed using qualitative content analysis. RESULTS: Survivors reported a median support network size of 2.2 persons (interquartile range = 1.2-3.8) and a median support satisfaction score of 5.5 (interquartile range = 5-6). While support satisfaction was found to be associated with QOL, no association was found between support network size and QOL. Interview findings revealed that close family members and peer survivors constituted the major source of breast cancer survivors' support, especially in emotional and informational support aspects. Cultural factors played a role in the perception and utilization of support of the breast cancer survivors. CONCLUSIONS: This study has indicated that support satisfaction is more critical than support network size in influencing various aspects of survivors' QOL through the underlying different types of situation-specific support.

    ABSTRACT: Objectives. To evaluate the sustaining effects of Tai Chi Qigong (TCQ) in improving the psychosocial health in chronic obstructive pulmonary disease (COPD) patients in the sixth month. Background. COPD affects both physical and emotional aspects of life. Measures to minimize patients' suffering need to be implemented. Methods. 206 COPD patients were randomly assigned into three groups: TCQ group, exercise group, and control group. The TCQ group completed a three-month TCQ program, the exercise group practiced breathing and walking exercise, and the control group received usual care. Results. Significant group-by-time interactions in quality of life (QOL) using St. George's respiratory questionnaire (P = 0.002) and the perceived social support from friends using multidimensional scale of perceived social support (P = 0.04) were noted. Improvements were observed in the TCQ group only. Conclusions. TCQ has sustaining effects in improving psychosocial health; it is also a useful and appropriate exercise for COPD patients.

    ABSTRACT: BACKGROUND: There is little in the literature exploring the inter-relationship of social support, prevalent symptoms and health-related quality of life (HRQoL) among breast cancer patients. This study examines the inter-relationships among the three variables using the 'Theory of Unpleasant Symptoms' as a framework. METHODS: 279 Chinese breast cancer patients undergoing treatment were recruited for face-to-face interviews. The instruments used were Chinese versions of the Brief Fatigue Inventory, Brief Pain Inventory, Hospital Anxiety and Depression Scales, Medical Outcomes Study Social Support Survey and Functional Assessment of Cancer Therapy for Breast Cancer. RESULTS: Goodness-of-fit and misfit indices were obtained for the final model (SRMR = 0.034, robust RMSEA = 0.051 and robust CFI = 0.981), and the results showed that social support had large total effects on social/family (total effect = 0.704, P < 0.05) and functional well-being (total effect = 0.450, P < 0.05), but a minimal effect on the breast cancer scale (total effect = 0.036, P > 0.05). CONCLUSIONS: The inter-relationships among the three variables give us a better understanding of breast cancer patients' experience and provide guidance for developing effective strategies to improve their HRQoL and relieving unpleasant symptoms.

    ABSTRACT: BACKGROUND:: The existing knowledge on fatalism in the field of cancer has arisen largely from the cancer prevention and screening literature. Little is known about the role of fatalism in cancer survivorship, particularly within Chinese population. OBJECTIVE:: This study aimed to explore the role of fatalism in coping with breast cancer survivorship in Chinese women. METHODS:: In-depth interviews were conducted on 29 participants selected from those who attended a local cancer self-help organization in China. Interview transcripts were transcribed and analyzed using qualitative content analysis. RESULTS:: Although they actively engaged in emotional regulation and self-care management to cope with survivorship, participants believed in fatalism and accepted their inability to change the final outcome of cancer. Such contradictory behavioral and cognitive aspects of coping reported by participants highlighted the role of a complex belief system involving Ming in positively influencing the interpretation of fatalism and the actual coping efforts taken. CONCLUSIONS:: Findings suggest that fatalism related to coping in the Chinese context combined 2 elements: fatalistic belief in and acceptance of the way things are as well as the exertion of personal efforts over the situation. As such, it seems more effectively depicted in terms of the emerging concept "fatalistic voluntarism." IMPLICATIONS FOR PRACTICE:: When planning intervention for Chinese population, incorporating fatalistic voluntarism as a cognitive belief system in the process of adaptation to survivorship may be more culturally relevant for facilitating their coping behaviors.

    ABSTRACT: BACKGROUND AND RESEARCH OBJECTIVE:: Post-myocardial infarction (MI) survivors are at a higher risk of coronary events. Therapeutic lifestyle changes, including dietary modification, have been emphasized as the cornerstone of secondary prevention. This study aimed to examine the effectiveness of a nurse follow-up dietary intervention (NFDI) on post-MI patients' dietary behavioral change (primary outcome) and blood lipid levels (secondary outcome). SUBJECTS AND METHODS:: A total of 82 post-MI subjects with borderline dyslipidemia were recruited and randomly allocated to a control group or an intervention group (IG) (n = 41/group). The control group received conventional care and attended a heart health dietary class. The IG received, in addition, a structured 8-week NFDI (including a face-to-face consultation session, a take-home self-management workbook, and fortnightly telephone follow-ups). Data were collected at 3 time points: baseline (T0), 1-week posttest (T1), 3-month posttest (T2). The effect of the intervention was assessed by a self-report questionnaire and blood tests. T test and time-by-group analysis of variance with repeated-measures analysis of variance were used. An intention-to-treat analysis was conducted. RESULTS:: Significant positive dietary changes were found among participants of the IG in reduced intake of saturated fat (F = 22.48, P < .001) and salted/preserved food (F = 13.58, P < .001) and increased intake of heart-healthy food (vegetables, fruit, nuts, and whole grains) (F = 40.88, P < .001). Although the results of secondary outcomes, triglyceride, and total cholesterol were not statistically significant, the high-density lipoprotein trend was in the expected direction for the IG (F = 8.982, P = .001). CONCLUSION:: This study found positive changes in dietary behavior and an increase in high-density lipoprotein level from participants who undertook the NFDI for self-management in dietary modification.

    ABSTRACT: Most studies related to addressing weight management of obese children have focused on understanding the perceptions of parents and health professionals. This study identifies the factors that obese children who have tried to lose weight perceive as affecting their efforts. This descriptive qualitative study has sought to identify factors affecting obese children's weight-loss decision making and process and to explore the development of an effective weight-loss program. This study screened 603 primary school children equivalent to U.S. Grades 5 and 6 of age 10-12. Seventy-nine out of 93 obese children who had been trying on their own to lose weight for at least 1 month formed 6 focus groups. Four themes were identified: Making the decision, self-efficacy, social influences, and environmental constraints. The results suggest that the design of a weight-loss program for obese children should include the contribution of family members, school, and health professionals.

    ABSTRACT: The purpose of the study was to investigate the effect of early ambulation after cardiac catheterization (CC) on patients' back pain, puncture site pain, vascular complications, urinary discomfort, general well-being perception and satisfaction level. This study was a randomized single-blinded controlled trial. Overall, 137 participants were randomly assigned to experimental (63 participants) or control (74 participants) group according to a computer generated random list. Early ambulation (ambulate at 4 hours post-CC) and routine post-procedure care of 12 to 24 hours were used in the experimental and control groups respectively. Independent t-test, Chi-square test, multiple logistic regression and generalized estimation equation model were applied to compare various outcomes between experimental and control groups. Only one patient in the control group experienced puncture site bleeding after CC. Ambulation at 4 hours after CC significantly reduced patients' back pain 8 hours after they returned to the unit (OR=0.19, 95% CI: 0.08-0.45, p<0.001) and in the next morning (OR=0.36, 95% CI: 0.15-0.87, p=0.023), decrease urinary discomfort (OR=0.35, 95% CI: 0.14-0.90, p=0.03 for "very or unbearable urination discomfort" and OR=0.22, 95% CI: 0.06-0.74, p=0.015 for "much difficulty or unable to urinate at all"), and increase general well- being (p=0.005 for vitality subscale and p=0.014 for the total general well-being). However, it made no significant differences on puncture site pain as well as the satisfaction level of patients. The study enhanced health providers' understanding about the effects of early ambulation on patient outcomes. Nurses may provide more individualized and appropriate care to post-CC patients in a more competent and cost-effective way.

    ABSTRACT: Abstract Coronary artery disease (CAD) is one of the leading causes of death and morbidity worldwide, and cardiac catheterization plays an essential role in its diagnostic evaluation. This quasi-experimental study examined the effectiveness of an educational intervention with the use of videotape and pamphlet among the Chinese patient undergoing the cardiac catheterization, and explored the relationship between anxiety, uncertainty, and other psychological variables. One hundred and thirty two Chinese patients of diagnosed or suspected CAD preparing for the first-time catheterization were recruited. Anxiety level (the Chinese State-Anxiety Inventory) and uncertainty (the Chinese version of Mishel Uncertainty in Illness Scale) were measured before the intervention and within 2 hours before receiving cardiac catheterization; while patients' satisfaction and perceived knowledge gain were measured at 20-24 hours after it. The mean age of the participants was 61.3 and 64.8% of them were male. The findings indicated that the use of videotape to prepare patients for the cardiac catheterization is effective in reducing the level of anxiety (p<0.001) and the uncertainty (p<0.001), as the patients experienced higher satisfaction and knowledge level after the educational intervention. Therefore, videotape education is suggested for cardiac catheterization care on top of the usual pamphlet education.

    ABSTRACT: To explore the experiences of patients with coronary heart disease in China. The morbidity and mortality rates of people with coronary heart disease have been growing rapidly in the past decades in China, yet little is known about the experiences of Chinese patients with the disease. A qualitative descriptive study. Face-to-face semi-structured interviews were employed in this study. Using a purposive sample, 11 participants who had been diagnosed with coronary heart disease for at least one month were recruited. A content analysis was used to identify themes. Three themes were identified from the data: experiencing a life-threatening illness, strategies for adapting to living with coronary heart disease and help-seeking behaviour. Chinese patients with coronary heart disease experienced the disease as a life-threatening illness related to chest pain. Chinese culture, values and beliefs influenced their adaptation strategies and help-seeking behaviour. Their misconceptions about coronary heart disease and the information needs for lifestyle changes were evident in this study. This study highlights the need for health education to support coronary heart disease patients in China. The findings provide useful information for Chinese health professionals to develop interventions for Chinese patients with coronary heart disease.
