This study aimed to identify the effects of utilizing Smartphone Application Peer Support (SAPS) on health behavior and body mass index (BMI) among overweight or obese breast cancer survivors (BCS).

A nonequivalent control group with a non-synchronized design was utilized and 36 participants (experimental group 14, control group 22) were recruited from August 2017 to September 2018. Participants were 40~65 years old, overweight or obese, had completed primary cancer treatment within the 12 months prior to the study, and had not done regular exercise during the last 6 months. The 3-month SAPS consisted of exercise and diet education (once p/2 weeks), peer support (once p/week), and self-monitoring using smartphone applications (5 times p/week). All participants underwent assessments at baseline, right after SAPS, and at 3 months after SAPS. Data were analyzed using repeated measures ANOVA.

At the completion of SAPS significant differences were found between groups in motivation for exercise (t=-3.24, p=.005), physical activity (t=-4.15, p<.001), total calorie intake (t=3.42, p=.002), calories from fat (t=-3.01, p=.005), intake of vegetables (t=-2.83, p=.008), and BMI (t=5.21, p<.001). Significant differences in BMI (t=4.13, p<.001) remained up to 3 months after SAPS completion. No significant differences was shown between groups in self-efficacy for exercise, either immediately after or 3 months after SAPS.

The SAPS has the potential to improve motivation for exercise, health behavior, and BMI of BCS. However, special efforts are required to encourage participants to complete the intervention and maintain long-term effects for future trials.

This study aimed to develop and test a structural model for chemotherapy-related cognitive impairment of breast cancer patients based on a literature review and Hess and Insel's chemotherapy-related cognitive change model.

The Participants consisted of 250 patients who were ≥19 years of age. The assessment tools included the Menopause Rating Scale, Symptom Experience Scale, Hospital Anxiety and Depression Scale, Everyday Cognition, and Functional Assessment of Cancer Therapy-Breast Cancer. Data were analyzed using the SPSS 21.0 and AMOS 21.0 programs.

The modified model was a good fit for the data. The model fit indices were χ ²=423.18 (p<.001), χ ²/df=3.38, CFI=.91, NFI=.91, TLI=.89, SRMR=.05, RMSEA=.09, and AIC=515.18. Chemotherapy-related cognitive impairment was directly influenced by menopausal symptoms (β=.38, p=.002), depression and anxiety (β=.25, p=.002), and symptom experiences (β=.19, p=.012). These predictors explained 47.7% of the variance in chemotherapy-related cognitive impairment. Depression and anxiety mediated the relations among menopausal symptoms, symptom experiences, and with chemotherapy related cognitive impairment. Depression and anxiety (β=-.51, p=.001), symptom experiences (β=-.27, p=.001), menopausal symptoms (β=-.22, p=.008), and chemotherapy-related cognitive impairment (β=-.15, p=.024) had direct effects on the quality of life and these variables explained 91.3%.

These results suggest that chemotherapy-related toxicity is highly associated with cognitive decline and quality of life in women with breast cancer. Depression and anxiety increased vulnerability to cognitive impairment after chemotherapy. Nursing intervention is needed to relieve chemotherapy-related toxicity and psychological factor as well as cognitive decline for quality of life in patients undergoing chemotherapy.

The purpose of this study was to examine the effects of integrated psychoeducational program for distress management of newly diagnosed patients with breast cancer.

A quasi-experimental trial was conducted. The participants consisted of 47 female patients with breast cancer assigned to an intervention group (n=25) and control group (n=22). The intervention group participated in integrated psychoeducational program, consisting of individual face-to-face education and telephone-delivered health-coaching sessions. Data were collected at three time points: pre-intervention (T1), post-intervention (T2), and 6-month follow-up (T3). Study instruments were Distress thermometer, Supportive Care Needs Survey Short Form 34 and Functional Assessment of Cancer Therapy-Breast.

Compared with the control group, breast cancer patients in the intervention group reported lower distress and supportive care needs than the control group. The intervention group reported higher quality of life (QOL) overall and higher emotional well-being than the control group.

These findings indicate that the integrated psychoeducational program is an effective intervention for reducing distress and supportive care needs and increasing QOL of newly diagnosed patients with breast cancer. Oncology nurses need to provide psychoeducational intervention to support patients with breast cancer in managing their distress and helping them adjust to their life.

The purpose of this study was to test the mediating effect of social support and resilience on the relationship between symptom distress and coping in young Korean breast cancer survivors.

A purposive sample of 209 young breast-cancer survivors (mean age 39.9) was recruited for a cross-sectional survey, and the data were collected between June and October 2015. The instruments used in this study were the Memorial Symptom Assessment Scale-Short Form, the Multidimensional Scale of Perceived Social Support, 10-item Connor-Davidson Resilience Scale, and Cancer Coping Questionnaire. The collected data were then analyzed using the SPSS 23.0 and AMOS 23.0 programs.

Symptom distress was found to have a significant indirect effect on coping (beta=-.32, p=.002), but not a significant direct effect (beta=.06, p=.577). Additionally, based on the values obtained for the squared multiple correlation, symptom distress, social support, and resilience were found to explain 46.4% of the total variance of coping.

Based on the results of this study, it can be suggested that in order to enhance young breast cancer survivors’ ability to cope with the distress they commonly feel, intervention methods that strengthen resilience and provide social support should be developed and made available to them.

The purpose of this study was to examine the mediating effect of marital intimacy on the impact of uncertainty on the quality of life (QoL) of young breast cancer patients.

This study used a pathway analysis with 154 young breast cancer cases in their early diagnosis stage at a medical center in Korea. Data were collected from November 2016 to February 2017 and analyzed using correlation analysis and pathway analysis.

Uncertainty, marital intimacy, and 4 sub-scales of QoL showed a significant correlation. Marital intimacy was directly affected by uncertainty (b=-.39, p=.013) and 4 sub-scales of QoL were also affected by uncertainty. Among the 4 sub-scales of QoL, physical well-being (PWB) (b=.17, p=.026), social well-being (SWB) (b=.49, p=.010), and functional well-being (FWB) (b=.38, p=.009) were affected by marital intimacy but emotional well-being (EWB) was not affected by it. The mediating effect of marital intimacy on the impact of uncertainty on QoL was confirmed. Marital intimacy showed a significant indirect effect on PWB (b=-.07, p=.024), SWB (b=-.19, p=.008), and FWB (b=-.15, p=.005), and it means that marital intimacy has a partial mediating effect on the impact of uncertainty on PWB, SWB, and FWB.

Effects of uncertainty on QoL was mediated by marital intimacy of young breast cancer patients in their early diagnosis stage. It suggests that marital intimacy needs to be considered in providing nursing intervention for young breast cancer patients.

The purpose of this study was to determine the effect of EPMLM(educational program of manual lymph massage) on the arm functioning and QOL(quality of life) in breast cancer patients with lymphedema.

Subjects in the experimental group(n=20) participated in EPMLM for 6 weeks from June to July, 2005. The EPMLM consisted of training of lymph massage for 2 weeks and encourage and support of self-care using lymph massage for 4 weeks. The arm functioning assessed at pre-treatment, 2weeks, and 6weeks using Arm functioning questionnaire. The QOL assessed at pre-treatment and 6 weeks using SF-36. The outcome data of experimental group was compared with control group(n=20). The collected data was analyzed by using SPSS 10.0 statistical program.

The arm functioning of experimental group was increased from 2 weeks after(W=.224, p=.011) and statistically differenced with control group at 2 weeks(Z=-2.241, p=.024) and 6 weeks(Z=-2.453, p=.013). Physical function of QOL domain increased in experimental group(Z=-1.162, p=.050), also statistically differenced with control group(Z=-2.182, p= .030) at 6weeks.

The results suggest that the educational program of manual lymph massage can improve arm functioning and physical function of QOL domain in breast cancer patients with lymphedema.

The purpose of this study was to investigate the effect of a comprehensive rehabilitation program on physical function, immune response, fatigue and quality of life in mastectomy patients.

The subjects included fifty-five patients with breast cancer (27 in the control group and 28 in the experimental group). The subjects in the experimental group participated in a comprehensive rehabilitation program for10 weeks, which was composed of 1 session of education, 2 sessions of stress management, 2 sessions of exercise, and 1 session of peer support group activity per week.

The results revealed anincrease in shoulder extension, abduction, external rotation, and internal rotation of the affectedupper extremity, and in shoulder extension and abduction of the healthy upper extremity. Also an increase in quality of life and a decrease in fatigue were significantly higher in the experimental group than the control group. However, the results revealed that the natural killer cell ratio of the experimental group increased but there was no significant difference from that of the control group.

The 10-week comprehensive rehabilitation program showed a large affirmative effect on physical function, fatigue and quality of life of breast cancer patients after a mastectomy.

The purpose of this study was to explore decision making experiences of Korean women with breast cancer who underwent breast reconstruction with/after a mastectomy.

Data were collected during 2015-2016 through individual in-depth interviews with 10 women who had both mastectomy and breast reconstruction, and analyzed using phenomenological method to identify essential themes on experiences of making a decision to have breast reconstruction.

Five theme clusters emerged. First, “expected loss of sexuality and discovery of autonomy” illustrates various aims of breast reconstruction. Second, “holding tight to the reputation of doctors amid uncertainty” specifies the importance of a trust relationship with their physician despite a lack of information. Third, “family members to step back in position” describes support or opposition from family members in the decision making process. Fourth, “bewilderment due to the paradox of appearance-oriented views” illustrates paradoxical environment, resulting in confusion and anger. Lastly, “decision to be made quickly with limited time to oneself” describes the crazy whirling process of decision making.

Findings highlight aims, worries, barriers, and facilitators that women with breast cancer experience when making a decision about breast reconstruction. Deciding on breast reconstruction was not only a burden for women in a state of shock with a diagnosis of breast cancer, but also an opportunity to decide to integrate their body, femininity, and self which might be wounded from a mastectomy. These findings will help oncology professionals provide effective educational counselling before the operation to promote higher satisfaction after the operation.

Posttraumatic growth (PTG) is defined as 'positive psychological change experienced as a result of a struggle with highly challenging life circumstances'. The purpose of this study was to identify the level of PTG and its correlates in Korean patients with breast cancer.

A sample of 120 participants was recruited from outpatients, who had successfully completed primary treatment of breast cancer at a university hospital., Data were collected from June to December, 2014 using Posttraumatic Growth Inventory, lllness Intrusiveness Rating Scale, Cancer Coping Questionnaire, Revised Life Orientation Test and The Multidimensional Scale of Perceived Social Support.

Total score for the PTG was 79.18±17.54 in patients surviving breast cancer. Bivariate analyses indicated that PTG was positively associated with having a religion, perceived social support, greater optimism, cancer coping, and illness intrusiveness. Results of the regression analysis showed that cancer coping (β=.29, p=.001), optimism (β=0.28, p=.001) and illness intrusiveness (β=0.17, p=.037) were statistically significant in patients' PTG.

The research findings show that the variables of cancer coping, optimism and illness intrusiveness significantly explain PTG and these psychological variables can be used to provide improvement in PTG for patients with breast cancer

The purpose of this study was to construct and test a structural equation model on resilience of breast cancer patients receiving chemotherapy.

Participants were 204 patients with breast cancer who received chemotherapy treatment. They participated in a structured interview, which included social support, depression, symptom experience, self-efficacy, hope, resilience, and infection prevention behaviors. Data were analyzed using SPSS/WIN 20.0 and AMOS 18.0.

Lower depression (γ=-.33, p=.020) and symptom experience (γ=-.31, p=.012) and higher self-efficacy (γ=.32, p=.005) and hope (γ=.48, p=.016) were influenced by higher social support. Greater resilience was influenced by lower symptom experience (β=-.18, p=.016), higher self-efficacy (β=.49, p=.023), and higher hope (β=.46, p=.012), and these predictors explained 66.7% of variance in resilience. Greater resilience (β=.54, p=.009) made an impact on greater infection prevention behaviors. Resilience mediated the relations of symptom experience (β=-.10 p=.013), self-efficacy (β=.27, p=.006) and hope (β=.25, p=.009) with infection prevention behaviors. These predictors explained 24.9% of variance in infection prevention behaviors.

The findings of the study suggest that breast cancer patientsw ith greater resilience who are receiving chemotherapy participate in increased infection prevention behaviors. Further research should be conducted to seek intervention strategies that improve breast cancer patients' resilience.

The purpose of this study was to develop a scale to evaluate empowerment in woman with breast cancer and to examine the validity and reliability of the scale.

The development process for the initial items included a literature review, interviews, and construction of a conceptual framework. The identified items were evaluated for content validity by experts, resulting in 3 factors and 48 preliminary items. Participants were 319 women with breast cancer recruited to test reliability and validity of the preliminary scale. Data were analyzed using item analysis, confirmatory factor analysis, criterion related validity, internal consistency and test-retest reliability.

The final scale consisted of 30 items and 3 factors. Factors, including 'intrapersonal factor' (14 items), 'interactional factor' (8 items), and 'behavioral factor' (8 items), were drawn up after confirmatory factor analysis. Goodness of fit of the final research model was very appropriate as shown by χ²/df=1.86, TLI=.90, CFI=.92, SRMR=.06, and RMSEA=.05. Criterion validity was evaluated by total correlation with the Cancer Empowerment Questionnaire .78. Cronbach's alpha for total items was .93 and test-retest reliability was .69.

Findings from this study indicate that the scale can be used in the development of nursing interventions to promote the empowerment of women having breast cancer.

Evidence suggests that some patients with breast cancer experience cognitive difficulties following chemotherapy. This longitudinal study was done to examine the prevalence of cognitive impairment and trajectory of cognitive function over time in women with breast cancer, who received adjuvant chemotherapy.

Participants were 137 patients with breast cancer. They completed neuropsychological tests and the Functional Assessment of Cancer Therapy-Cognitive Function before adjuvant therapy (pretest), toward the end of adjuvant therapy (posttest), and 6 months after the completion of adjuvant therapy (follow-up test). Of the patients, 91 were treated with adjuvant chemotherapy and 46 patients who did not receive chemotherapy made up the comparison group. A reliable-change index and repeated-measure ANOVA were used for statistical analyses.

At the posttest point, over 30% of patients showed complex cognitive impairment and reported greater difficulty in subjective cognitive function. At the follow-up test point, 22.0% of patients exhibited complex cognitive impairment and 30.8% of patients complained of subjective cognitive impairment. Repeated-measure ANOVA showed significant decreases after receiving chemotherapy followed by small improvements 6 months after the completion of chemotherapy in cognitive domains of change for attention and concentration, memory, executive function, and subjective cognitive function.

These results suggest that chemotherapy in patients with breast cancer may be associated with objective and subjective cognitive impairments. Further studies are needed to explore the potential risk factors and predictor of chemotherapy-related cognitive changes. Also nursing interventions for prevention and intervention of cognitive impairments should be developed and tested.

The purpose of the study was to identify degrees of pain, menopause symptoms, and quality of life, and to identify factors influencing quality of life of patients with breast cancer who were on hormone therapy.

A cross-sectional survey design was utilized. Data were collected using questionnaires from 110 patients with breast cancer who had been on hormone therapy for 3 months or more and were being treated at a university hospital in Seoul. Data were analyzed using χ²-test, t-test, ANOVA, Pearson correlation coefficient and multiple linear regression.

Mean age of the participants was 53.56 (SD=6.67) and 54 (51.4%) had stage 0 or I at the time of diagnosis. Most of the participants reported having pain and menopause symptoms (88.2% and 95.5% respectively). The mean score for quality of life was 87.84±21.17. Pain, menopause symptoms and quality of life had strong correlations with each other (p<.005). Quality of life was explained by menopause symptoms (β= -.71), economic status (β=.20) and occupation (β=.16).

The results of the study suggest that menopause symptoms should be incorporated into oncologic nursing care to improve quality of life of patients with breast cancer on hormone therapy.

A diagnosis of breast cancer is one of the most traumatic events that threatens a woman's life, but while women adapt to and overcome these threats, they not only experience negative aspects, but also growth. The purpose of this study was to identify the many factors that affect growth, and to provide fundamental information for nursing interventions, which can help the women in their growth.

The participants in this study were 131 married women patients with breast cancer, who were on medical treatment in one of two university hospitals, in Seoul and Chungnam. Data were collected for posttraumatic growth, self-esteem, cancer coping questionnaire, marital intimacy, and body image. The data were analyzed using the SPSS 19.0 program (IBM).

Interpersonal cancer coping, intrapersonal cancer coping (planning) and self-esteem accounted for 29.0% of posttraumatic growth.

These findings indicate that in order to help the women's growth after the trauma of breast cancer, it is necessary to enhance their self-esteem, and to develop psycho-social nursing supportive programs.

The purpose of this study was to evaluate the cognitive effects of chemotherapy in patients with breast cancer.

Using several databases, prospective studies were collected up to August 2011. Of 2,106 publications identified, 12 met the inclusion criteria, and 8 studies were used to estimate the effect size of chemotherapy on cognitive impairment.

Twelve studies were done since 2005 and most of the research was performed in Europe or North America. Eight studies were used to generate effect size across the cognitive domains of attention/concentration, verbal and visual memory, executive function, visuospatial skill, language, and subjective cognitive function. Each of the cognitive domains showed small effect sizes (-0.02 ~ -0.26), indicating diminished cognitive function for the chemotherapy group compared with non-chemotherapy groups.

Finding suggests that breast cancer patients who undergo chemotherapy may experience mild cognitive decline. Further study is needed to generate knowledge and guideline for interventions to address chemotherapy related cognitive impairment in these patients.

To develop a expressive writing program for women with breast cancer and to identify its effects on stress physical symptom, cancer symptom, anxiety, depression, and QOL.

A non-equivalent control pre-post design was used. Participants were recruited from self-help groups in six hospitals and were assigned to the experimental group (29) or control group (29). Data were collected before, after, and at four weeks after the intervention program. Changes in the variables were evaluated to test effects of the developed program, using χ²-test, Fisher's exact test, repeated measures ANOVA, and paired t-test.

The expressive writing program was developed for women with breast cancer based on Pennebaker's expressive writing. Significant differences were found between the two groups for stress related to physical symptoms (p<.00) and quality of life (p=.024). No significant differences were found in cancer symptoms, anxiety, or depression between the two groups.

The results indicate that the expressive writing program designed to express cancer-related deep thoughts and emotions helps in decreasing physical symptoms and improving QOL. Further studies are needed to identify the effect on emotions such as anxiety and depression for women with breast cancer with above average levels of anxiety and depression.

The purpose of this study was to develop and implement the Hospice Smart Patient Program and to evaluate its effectiveness.

It was quasi-experimental non-equivalent pre-post study. Breast cancer patients who underwent surgery, chemotherapy or radiotherapy, or who needed palliative care, participated in the study. Participants were divided into two groups, experimental and control groups based on their preferences. The program was developed after literature review and discussion among experts on hospice and palliative care. Participants who were in the experimental group received either face-to-face or phone 「Hospice Smart Patient」 Service at least once a week for 5 months.

There was a significant difference in quality of life and communication skill between the two groups after the service was provided. In addition, participants in experimental group showed improved decision making skills, mastery sense, and understanding of hospice and palliative care, which would be beneficial in improving their quality of life.

We have concluded that the 「Hospice Smart Patient」 Program is useful for cancer patients in decision making, improving self-control and choosing hospice care to improve their quality of life.

The purposes of this study were to evaluate symptom experience and quality of life (QOL) and to identify the predictors of QOL among breast cancer survivors.

A cross-sectional study was conducted on 200 disease-free breast cancer survivors at two hospitals between December 2007 and July 2008. Functional Assessment of Cancer Therapy Scale-B, Memorial Symptom Assessment Scale-short Form and The Linear Analogue Self Assessment Scale were used to assess symptom experience and QOL in these patients. Data were analyzed using the Pearson correlation, t-test, ANOVA, and stepwise multiple regression with SPSS/WIN 12.0.

The mean score of QOL for breast cancer survivors was 95.81 (±18.02). The highest scores among physical and psychological symptoms were sexual interest and anxiety. Year since treatment completion was significantly associated with QOL in sociodemographic variables. Physical and psychological symptoms have a significant negative association with QOL. The results of the regression analyses showed that physical and psychological symptoms were statistically significant in predicting patients' QOL.

Symptom experience and QOL are essential variables that should be acknowledged when delivering health care to breast cancer survivors. More attention to the reduction and management of psychological distress could improve QOL among breast cancer survivors.

The purpose of this study was to analyze the effects of a cognitive-behavioral nursing intervention on anxiety and depression of patients with breast cancer undergoing radiotherapy.

A nonequivalent control group design was used for the study. The research participants were patients with breast cancer (N=71; experimental group=35, comparison group=36) who received radiotherapy at P university hospital. The experimental group received a 6-week cognitive-behavioral nursing intervention (2 hr/week), which included nursing counseling, education about treatment choices for breast cancer and possible side effects and management strategies during radiotherapy, and rehabilitation exercise.

Following the intervention, the experimental group showed significantly lower levels of anxiety (Experimental group=34.60±6.35, Comparison group=44.63±9.93, t=3.552, p<.001) and depression (Experimental group=10.20±6.61, Comparison group=17.81±10.85, t=3.542, p<.001) than the comparison group.

The findings from this study showed that cognitive-behavioral counseling applied by nurses is very effective to reduce anxiety and depression among patients with breast cancer. Therefore, providing nursing counseling to broader spectrum of patients with cancer should be considered. Further research would warrant future clinical application of nursing counseling.
