Chemotherapy-related symptoms in children with leukemia: application of latent profile analysis and network analysis.

PURPOSE: Children with leukemia may experience a range of chemotherapy-related symptoms. Identifying subgroups and their distinct characteristics of symptoms may improve symptom management. We aimed to identify subgroups and their distinct characteristics of chemotherapy-related symptoms in children with leukemia. METHODS: A cross-sectional survey was conducted among 500 children with leukemia, who completed questionnaires that assessed their demographic and clinical characteristics, as well as the Memorial Symptom Assessment Scale. Latent profile analysis was conducted to identify subgroups of symptoms. Additionally, multiple regression analysis and network analysis were utilized to reveal the characteristics of each subgroup. RESULTS: Four subgroups were identified: "Profile 1: low symptom burden subgroup" (26.2%), "Profile 2: moderate symptom burden subgroup in transitional period" (14.8%), "Profile 3: moderate psychological symptom burden subgroup" (35.6%), and "Profile 4: high symptom burden subgroup" (23.4%). Multiple logistic regression analysis indicated that lower primary caregiver's education level, lower family monthly income, self-paid medical expenses, induction remission period, and consolidation enhancement period were associated with more severe symptoms of subgroups. Network analysis further revealed that nausea was the core symptom in Profiles 1 and 2, while the core symptom in Profile 3 was "I don't look like myself." Additionally, worrying was the core symptom in Profile 4. CONCLUSION: There exists heterogeneity in chemotherapy-related symptoms. Four subgroups and their corresponding characteristics of children with varying symptom severity were identified. Identifying these subgroups will facilitate personalized care, maximize intervention effectiveness, and alleviate symptom burden.

Simplified Chinese version of the PROMIS Pediatric-25 profile: A validation study among cancer children.

PURPOSE: Pediatric cancer is a significant health concern in China, and evaluating the impact of cancer and its treatment on the well-being of young patients is essential for both clinical care and research purposes. This study aimed to psychometrically validate the Patient-reported Outcomes Measurement Information System Pediatric-25 Profile (PROMIS-Pediatric-25) among Chinese children with cancer. DESIGN AND METHODS: We enrolled a group of 114 children living with cancer between the ages of 8 and 17. Each participant completed questionnaires that covered sociodemographic and clinical information and the PROMIS-Pediatric-25. The floor and ceiling effect was examined. Cronbach's alpha and split-half coefficient were examined to determine the reliability. Factor structure was explored by factor analysis. Three assumptions of Rasch model-based item response theory (IRT) were assessed. Differential item functioning (DIF) was investigated concerning factors of gender, diagnosis, and treatment stage. RESULTS: The floor or ceiling effects were detected for six domains. The reliability was found to be excellent. Furthermore, the factor structure of these six domains was validated. Our analysis confirmed that the assumptions required for IRT were met with acceptable unidimensionality, local independence, and good monotonicity. Additionally, we observed measurement equivalence, with outstanding levels of DIF across factors such as gender, diagnosis, and treatment stage. CONCLUSION: PROMIS-Pediatric 25 is a highly reliable and valid instrument for evaluating key domains of health-related quality of life in Chinese pediatric cancer patients. PRACTICE IMPLICATION: Nursing practice could engage the PROMIS-Pediatric 25 for accurate and quick children symptom and function assessment.

Determining the optimal cut-off scores for the Chinese version of the Memorial Anxiety Scale for Prostate Cancer (MAX-PC).

PURPOSE: Anxiety is a common emotion experienced by patients with prostate cancer (PCa), and can be exacerbated by testing the prostate-specific antigen (PSA) index. The Memorial Anxiety Scale for Prostate Cancer (MAX-PC) was developed to assess the cancer-specific anxiety of these patients, but lack of appropriate thresholds for this scale limits its use. This study aimed to utilize ROC curve analysis to identify the best cut-off values for the Chinese version of the MAX-PC scale. METHODS: A cross-sectional survey was conducted using the Chinese version of the MAX-PC scale and the Generalized Anxiety Disorder Scale (GAD). ROC curve analysis, Youden index, Kappa consistency test and McNemar test were used for the optimal cutoff points for screening mild, moderate, and severe cancer-specific anxiety levels in patients with PCa, on the Chinese version of the MAX-PC scale. RESULTS: Two hundred eighty-seven patients with PCa completed the survey. The appropriate cut-off values for the MAX-PC scale for screening patients with PCa for cancer-specific anxiety were 20, 28, and 38 for mild, moderate, and severe anxiety, respectively with the highest Youden indices. The Kappa and McNemar's test showed the best level of consistency with values of 0.627, 0.580, and 0.606 for screening mild, moderate, and severe anxiety, respectively. CONCLUSIONS: The scores 20, 28, and 38 are the best cut-off values for the Chinese version of the MAX-PC scale. This scale should be used for screening cancer-specific anxiety for patients with PCa to assess and evaluate their anxiety levels and provide targeted interventions.

Psychometric properties of the Chinese version of the PROMIS-Cancer-Anxiety item bank assessed using a graded response model.

Objective: This study aimed to examine the psychometric properties of the Chinese version of the Patient-Reported Outcome Measurement Information System (PROMIS)-Cancer-Anxiety item bank using a graded response model in a sample of patients with cancer. Methods: A cross-sectional study was conducted and the Chinese version of the PROMIS-Cancer-Anxiety item bank was used to measure anxiety in patients with cancer. The unidimensional structure of the item bank was evaluated using principal component analysis. Residual correlations and the graphs of item mean scores conditional on the rest scores were examined to evaluate the local independence and monotonicity of the items, respectively. Item characteristics were described using item parameter estimates and item information. Operating characteristic curves (OCCs) and test information curve (TIC) were also plotted. Measurement invariance across age, gender, and education level was assessed to identify possible differential item functioning (DIF). Results: A total of 1075 patients with cancer were enrolled. Under the assumptions of unidimensionality, local independence, and monotonicity, the discrimination parameters a ranged from 2.30 to 5.47, and the threshold parameters b ranged from b1 = -2.87 to b4 = 3.21 with proper intervals. Completely overlapped category curves were not observed among the OCCs of any items. Item information and TIC showed that the item bank had a wide measurement range. The DIFs for age, gender, and education level for all items were not remarkable. Conclusions: The results supported using the Chinese version of the PROMIS-Cancer-Anxiety item bank to measure anxiety and develop a computerized adaptive testing (CAT) system for anxiety in patients with cancer.

Effects of routine collection of patient-reported outcomes on patient health outcomes in oncology settings: A systematic review.

Objective: This study aims to investigate the potential benefits of integrating patient-reported outcomes (PROs) into routine clinical practice for patients undergoing active anticancer treatment. Methods: We conducted a comprehensive systematic review of randomized controlled trials involving cancer patients undergoing active anticancer treatment, spanning various cancer types and stages. The review covered four electronic databases (Medline, EMBASE, Cochrane Library, and CINAHL) up to September 2022. Key inclusion criteria focused on the incorporation of PROs as a routine intervention. Bias assessment followed the Cochrane collaboration's criteria, while the synthesis of results utilized effect size measurements (Cohen's d). The study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Out of 1549 initially screened records, 16 published randomized controlled trials encompassing 5300 patients met the inclusion criteria. The interventions involved 18 different PROs measurements, with prominent tools being EORTC QLQ-C30 (utilized in four trials) and PRO-CTCAE (utilized in four trials). Measured endpoints included overall quality of life (12 trials), physical health (11 trials), mental health (7 trials), and social health (5 trials). Overall, the study revealed a limited number of statistically significant findings, with predominantly small to moderate effect sizes associated with the interventions. Conclusions: The findings suggest that the routine integration of PROs into clinical practice does not yield definitive advantages in terms of PROs. It is apparent that further efforts are necessary to ascertain the impact of these interventions on patient health. Systematic review registration: The review protocol was registered on PROSPERO (ID: CRD42022365456).

Psychometric properties of the Chinese version of the functional assessment of chronic illness therapy-fatigue (FACIT-F) among patients with breast cancer.

BACKGROUND: Fatigue is the most frequent and distressing symptom affecting the physical, cognitive, and affective domains of breast cancer patients. The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) has been widely used in patients with chronic diseases and has shown satisfactory reliability and validity. This study aimed to examine the psychometric properties of the FACIT-F among Chinese patients with breast cancer. METHODS: Using a convenience sampling method, a cross-sectional survey (January 2020 and September 2022) was used with patients recruited from two tertiary hospitals in Shanghai, Mainland China, and a total of 597 patients completed a demographic information questionnaire, the FACIT-F and the Functional Assessment of Cancer Therapy for Breast Cancer (FACT-B). Convergent validity was estimated by calculating the Pearson correlation coefficient of the FACIT-F with the FACT-B. Measurement invariance across age was performed by examining differential item functioning (DIF) across age groups (≤ 60 and > 60 years). The internal consistency and split-half reliability were performed for reliability analysis. Unidimensionality of the scale was evaluated by the principal component analysis by Rasch analysis. Additionally, Rasch analysis was performed for item difficulty levels, and an item-person map was used. RESULTS: No floor/ceiling effects were observed for the FACIT-F. Moderate correlations were found between FACIT-F and FACT-B (r = - 0.342, p < 0.01). Most items showed an absence of DIF regarding age, except for one item. In addition, the FACIT-F showed acceptable internal consistency. Principal component analysis of Rasch residuals showed that the proportion of variance explained by the FACIT-F was 53.3%, and the outfit mean square statistics for the items ranged from 0.68 to 1.90 and the infit MNSQ from 0.63 to 1.73. Additionally, an acceptable response between items and persons was found. CONCLUSIONS: The findings indicate that the Chinese version of the FACIT-F is a valid tool for the measurement of fatigue in breast cancer patients.

Validation of the simplified Chinese version of PROMIS Parent Proxy-25 Profile in parents of children with cancer.

PURPOSE: To determine the psychometric properties of the Patient-reported Outcomes Measurement Information System Parent Proxy-25 Profile (PROMIS-25) in a sample of Chinese parents of children with cancer. DESIGN AND METHODS: A cross-sectional sample (N = 148) of parents with children aged 5-17 years living with cancer was recruited. Each participant completed sociodemographic and clinical questionnaires and PROMIS-25. The flooring and ceiling effects were calculated. Reliability was determined by the Cronbach's alpha and split-half coefficient. Factor structure was examined by factor analysis. Model fit and graphical plots were assessed to test the assumptions of Rasch model-based item response theory (IRT). Differential item functioning (DIF) was assessed in terms of gender, age, and treatment stage. RESULTS: PROMIS-25 demonstrated some flooring and ceiling effect, excellent reliability (Cronbach's α > 0.7 for all six domains), and the six-domain factor structure was supported. The IRT assumptions were met in terms of unidimensionality, local independence, monotonicity, and measurement equivalence with acceptable DIF in terms of gender, age, diagnosis, and treatment stage. CONCLUSION: PROMIS-25 is a highly reliable and valid instrument for evaluating children with cancer that assesses important health-related quality of life domains of child cancer. PRACTICE IMPLICATION: Chinese parents of children with cancer and healthcare providers could use PROMIS-25 to assess the symptoms of children.

Cancer-related symptoms among young and middle-aged women undergoing chemotherapy for breast cancer: Application of latent class analysis and network analysis.

PURPOSE: To identify subgroups and symptom networks of cancer-related symptoms for women under 60 years who are undergoing chemotherapy for breast cancer. METHODS: A cross-sectional survey in Mainland China was conducted between August 2020 and November 2021. Participants completed questionnaires that collected demographic and clinical characteristics and featured the PROMIS-57 and the PROMIS-Cognitive Function Short Form. RESULTS: A total of 1033 participants were included in the analysis, and three-class model was identified: "severe symptom group" (17.6%; Class 1), "moderately severe anxiety, depression, and pain-interference group" (38.0%; Class 2), and "mild symptom group" (44.4%; Class 3). Patients who were in menopause (OR = 3.05, P < .001), undergoing a combination of medical treatments (OR = 2.39, P = .003), and who had experienced complications (OR = 1.86, P = .009) were more likely to belong to Class 1. However, having two or more children increased the likelihood of belonging to Class 2. Additionally, network analysis showed that severe fatigue level was the core symptom among the full sample. As for Class 1, feeling helpless and severe fatigue level were the core symptoms. Regarding Class 2, the impact of pain interfere on the ability to participate in social activities and feeling hopeless were found to be the targeted symptoms for intervention. CONCLUSION: Menopause, receiving a combination of medical treatments, and experiencing complications characterize the group with the most symptom disturbance. Moreover, different interventions should be performed for core symptoms in patients with varied symptom disturbances.

Identification of age differences in cancer-related symptoms in women undergoing chemotherapy for breast cancer in China.

BACKGROUND: Both contextual and cancer-related factors could be identified as causes of the interindividual variability observed for symptoms experienced during breast cancer treatment with chemotherapy. Understanding age differences and the predictors of latent class memberships for symptom heterogeneity could contribute to personalized interventions. This study aimed to identify the role of age differences on cancer-related symptoms in women undergoing chemotherapy for breast cancer in China. METHODS: A cross­sectional survey was conducted among patients with breast cancer in three tertiary hospitals in central China between August 2020 to December 2021. The outcomes of this study included sociodemographic and clinical characteristics, Patient-Reported Outcomes Measurement Information System (PROMIS)-57 and PROMIS-cognitive function short form scores. RESULTS: A total of 761 patients were included, with a mean age of 48.5 (SD = 11.8). Similar scores were observed across age groups for all symptoms except for fatigue and sleep disturbance domains. The most central symptoms varied among each group, and were fatigue, depression, and pain interference for the young-aged, middle-aged, and elderly-aged groups, respectively. In the young-aged group, patients without health insurance (OR = 0.30, P = 0.048) and in the fourth round of chemotherapy or above (OR = 0.33, P = 0.005) were more likely to belong to low symptom classes. In the middle-aged group, patients in menopause (OR = 3.58, P = 0.001) were more likely to belong to high symptom classes. In the elderly-aged group, patients with complications (OR = 7.40, P = 0.003) tended to belong to the high anxiety, depression, and pain interference classes. CONCLUSIONS: Findings from this study indicated that there is age-specific heterogeneity of symptoms present for Chinese women being treated for breast cancer with chemotherapy. Tailored intervention should consider the impact of age to reduce patients' symptom burdens.

An online 5-week professional identity program for nursing student in clinical rotation practice during the first wave of COVID-19 pandemic: A two-arm randomized trial.

AIM: Development and evaluation of the effectiveness of an online 5-week professional identity program among nursing students in clinical internship practice during the COVID-19 restrictions. BACKGROUND: Nurse professional identity is a strong predictor of career commitment. Clinical internship practice is a key stage when nursing students build and rebuild their professional identity. Meanwhile, the COVID-19 restrictions has strongly influenced the professional identity of nursing students as well as nursing education. A well-designed online professional identity program may contribute to nursing students who are in clinical internship practice developing positive professional identity during the COVID-19 restrictions. DESIGN: The study was a two-armed, randomised, controlled trial conducted and reported based on Consolidated Standards of Reporting Trials (CONSORT) 2010 guidelines. METHODS: A total of 111 nursing students undergoing clinical internship were randomised into an intervention group and a control group. The five-weekly session intervention was developed based on social identity theory and career self-efficacy theory. The primary outcomes were professional identity and professional self-efficacy and the second outcome was stress. Qualitative feedback was analysed by thematic analysis. Outcomes were assessed before and after the intervention and analysed using an intention-to-treat principle. RESULTS: The generalised linear model showed that group-by-time effects were significant for the total score of professional identity and three factors of professional self-image, social comparison and self-reflection and independence of career choice, with small effect sizes (Cohen's d from 0.38 to 0.48). Only one factor of the capacity of information collection and planning in professional self-efficacy was significant (Wald χ2 =0.4.82, P < 0.01) with a medium effect size (Cohen d=0.73). The group effect, time effect and group-by-time effect of stress were not significant. Three themes were: 'Gaining in professional identity, self-recognition and peer belonging'; 'Content, self-motivation and intervenor as participation facilitators'; and 'Combining offline and courses, setting group rules and building mutual trust as recommendations'. CONCLUSIONS: The online 5-week professional identity program effectively promoted the development of professional identity and the capacity for information collection and career planning but did not significantly relieve pressure during the internship.

Validity and reliability of the Chinese version of the Patient-Reported Outcomes Measurement Information System adult profile-57 (PROMIS-57).

BACKGROUND: The PROMIS-57 is a commonly used self-reported instrument to solve the lack of generalizable and universal measures required to evaluate common symptoms and functions from patients' perspectives. This study aimed to translate the PROMIS-57 into Chinese and psychometrically test the translated instrument on patients with breast cancer. METHODS: Translation, cross­cultural adaptation, and psychometric evaluation of the instrument were performed from June 2020 to June 2021. Eligible patients were recruited and completed the PROMIS-57, Functional Assessment of Cancer Therapy-Breast (FACT-B), and a sociodemographic questionnaire. RESULTS: Data from 602 patients with a mean age of 48.83 years were analyzed. Most domains in the PROMIS-57 showed an absence of floor and ceiling effects. Multi-trait scaling analysis demonstrated acceptable convergent and discriminant validity. The correlations between the PROMIS-57 scores and the selected FACT-B scores supported the criterion validity via the Pearson correlation test. Measurement invariance was supported by the absence of differential item functioning for most items. Cronbach's α of the domains ranged from 0.85-0.95. The unidimensional factor structure of all domains was supported using confirmatory factor analyses. Additionally, most items showed acceptable item information curves and item characteristics curve matrices. CONCLUSION: The Chinese version of the PROMIS-57 was found to be a reliable and valid tool for assessing common symptoms and functions among patients with breast cancer.

Risk factors for low self-care self-efficacy in cancer survivors: Application of latent profile analysis.

AIM: To identify subgroups of cancer patients with distinct self-care self-efficacy profiles and to explore factors that can be used to predict those at risk of low self-efficacy. DESIGN: A secondary analysis of data pooled from two cross-sectional surveys was performed. METHODS: In total, 1,367 Chinese cancer survivors were included in the analysis. Latent profile analysis (LPA) was performed to categorize participants into latent subgroups with distinct self-efficacy profiles. Multinomial logistic regression was conducted to identify predictors of self-care self-efficacy subgroup classification. RESULTS: We identified three distinct subgroups: low, medium and high self-care self-efficacy. Patients with the "low" profile, which was characterized by a low education level, single marital status, complications, late cancer stage and a lower level of social support, had the poorest self-care behaviour.

Psychometric validation of the Chinese version of the PROMIS Social Relationships Short Forms.

AIM: This study aimed to culturally adapt and psychometrically validate the PROMIS Social Relationships Short Forms (PROMIS-SR) among Chinese patients with breast cancer. DESIGN: A cross-sectional study. METHOD: The PROMIS-SR was translated into simplified Chinese by strictly adhering to the Functional Assessment of Chronic Illness Therapy translation method and was subsequently tested among patients with breast cancer (N = 965). Eligible patients filled out the demographic information questionnaire, the PROMIS-SR, and the Functional Assessment of Cancer Therapy-Breast. RESULTS: Confirmatory factor analysis (CFA) provided support for the original structure of the PROMIS-SR. All instruments reported strong known-group, cross-cultural and convergent validity, as hypothesized. Correlation coefficients ranged from 0.67 to 0.85, and Cronbach's α of all items were high (0.90-0.94).

Psychometric evaluation of the PROMIS social function short forms in Chinese patients with breast cancer.

BACKGROUND: The diagnosis of breast cancer and the subsequent treatment undermine patients' participation in social activities. This study aimed to carry out a cross-cultural adaption and analysis of the construct validity and reliability of the Chinese version of the PROMIS social function short forms in patients with breast cancer. METHODS: This study utilized a cross-sectional research design, and was registered in the Chinese Clinical Trial Registry (ChiCTR2000035439). After a standardized cross-cultural adaption process, a psychometric evaluation was performed of the Chinese version of the PROMIS social function short forms. Using convenience sampling, eligible patients with breast cancer from tertiary hospitals in China were enrolled from January 2019 to July 2020. Participants completed the sociodemographic information questionnaire, the PROMIS social function short forms, the Functional Assessment of Cancer Therapy-Breast, the PROMIS emotional support short form and the PROMIS anxiety short form. RESULTS: Data were collected from a sample of 633 patients whose mean age was 48.1 years. The measures showed an absence of floor and ceiling effects. Regarding construct validity, the results of confirmatory factor analysis supported the original two-factor structure of the PROMIS social function short forms. In addition, the measures were found to have acceptable known-group validity, measurement invariance, and convergent and discriminate validity. Regarding reliability, the Cronbach's α was high for all items (> 0.70). CONCLUSION: The Chinese version of the PROMIS social function short forms was demonstrated to be a valid and reliable measure for the assessment of social function in Chinese patients with breast cancer. Additional psychometric evaluation is needed to draw firm conclusions.

Attitudes toward and Perceptions of Educational Needs for End-of-Life Care among Health Professions Students: A Cross-Sectional Study in China.

CONTEXT: To provide effective end-of-life care education for health professions students, it is important to understand students' views of death in addition to their perceptions of educational needs and preferences. However, there is a lack of studies addressing interindividual variability in perceptions of end-of-life care educational needs among health professions students. OBJECTIVES: This study aimed to identify latent profiles of perceptions of end-of-life care educational needs among health professions students and examine whether the demographic characteristics, death-related events, death attitude, and death anxiety differed by need subgroup. METHODS: Through convenience sampling, health professions students from three universities in China were recruited between March 2020 and June 2020. Data were collected using a demographic information and death-related experience questionnaire, the End-of-Life Care Curriculum Needs Questionnaire, the End-of-Life Care Educational Needs Questionnaire, the Death Attitudes Profile-Revised, and the Templer's Death Anxiety Scale. RESULTS: A total of 1048 students completed the survey. Two classes of perceptions of end-of-life care educational needs were identified: approximately 29.80% of students belonged to a medium-need group class (1), and 70.20% belonged to a high-need group class (2). Being female and having knowledge of end-of-life care significantly increased the probability of membership in class 2. Students with the two latent profiles reported having varied curriculum needs. In addition, a positive attitude toward death and low death anxiety increased the probability of membership in class 1. CONCLUSION: Two classes of perceptions of end-of-life care educational needs were identified, and these classes were significantly associated with sex and death-related knowledge (P < 0.05). Interindividual variability should be considered in the future development of end-of-care curricula.

Physical activity in the context of advanced breast cancer: An integrative review.

AIMS: To describe and synthesize diverse empirical evidence regarding physical activity (PA) in the context of advanced breast cancer (ABC). DESIGN: Integrative review guided by the work of Whittemore and Knafl (2005). DATA SOURCES: Six electronic databases were systematically searched to identify relevant literature published between January 2007-June 2019. REVIEW METHODS: Abstracts of papers that met the inclusion criteria were reviewed by two researchers and full texts of eligible papers were assessed. Data were extracted by two independent researchers and inter-rater reliability of data extraction established. Quality of papers was evaluated using the Mixed Methods Appraisal Tool. Data were organized according to comprehensive thematic analysis and the biobehavioural model for the study of exercise interventions. RESULTS: Of the 532 abstracts, 18 studies met the inclusion criteria which included six randomized controlled trials, one quantitative non-randomized study, seven quantitative descriptive studies, three mixed method studies and one qualitative study. Results from studies enrolled fell into four domains: PA performance and its influence on survival; barriers and preferences for PA; interventions to enhance PA; perceived benefits of PA from qualitative feedback. CONCLUSION: Evidence suggests that ABC patients are physically inactive. Main barriers of PA are less aerobic fitness and heavy symptom burden. Simple, tailored and specialist-supervised PA is preferred by ABC patients. Form of joint self-instructed and group accompanying is advocated as well. PA intervention programmes identified in this review vary on type, intensity, duration and frequency, while generally, are found to be feasible, safe and beneficial to patients' physical and psychosocial well-being. IMPACT: The results propose tailored, supervised, group-based PA programmes are in urgent need for ABC patients. Clinical professionals should manage more feasible and safer PA interventions to help improve patients' overall health. More research with rigorous methodology design is warranted to explore PA's effect on long-term health outcomes.

Trajectory Patterns and Factors Influencing Self-management Behaviors in Chinese Patients With Breast Cancer.

BACKGROUND: Self-management plays an important role in improving quality of life among patients with breast cancer. Self-management behaviors change with treatment periods, and the trajectory varies in patients with different demographic and psychosocial characteristics. However, the trajectory patterns and the predictive factors have not been fully studied. OBJECTIVES: The aim of this study was to identify the trajectory patterns of self-management behaviors in Chinese patients with breast cancer and their predictive factors. METHODS: A total of 128 patients with breast cancer were recruited. Demographic and disease-related information, self-management behaviors, self-efficacy, coping modes, emotional distress, and social support were investigated across 5 time points. Growth mixture modeling was used to identify the trajectory patterns of self-management behaviors. Logistic regression was used to determine the predictors for membership. RESULTS: The best-fit growth mixture modeling revealed a 2-class model; model fit indices were all in acceptable ranges. Class 1 and 2 were named as the group of "stable" (34.38%) and the group of "sharply decreased" (65.62%), respectively, based on the tendency of change. Modified radical mastectomy, avoidance coping mode, anxiety, and low self-efficacy level were predictors of the patients' membership to the sharply decreased group. CONCLUSION: Our study proved the heterogeneity of self-management behaviors and the influencing effect of treatment and psychosocial factors on the development of self-management behaviors in Chinese patients with breast cancer. IMPLICATIONS FOR PRACTICE: Health professionals should pay more attention to patients who are at higher risk of developing a poor self-management pattern. Targeted interventions should be developed across subpopulations and treatment periods accordingly.

Translation, Validity, and Reliability of the Chinese Version of the Breast Cancer Survivor Self-efficacy Scale in China.

BACKGROUND: Self-efficacy is a crucial variable that is related to quality of life. Patients who have high self-efficacy will exert sufficient effort and have better health outcomes and improved quality of life. Appropriate and precise measurement of self-efficacy can help promote better care. The Breast Cancer Survivor Self-efficacy Scale (BCSES) is designed to measure the perceived confidence of breast cancer patients in managing the tasks for self-management. Originally developed in America, it has not been used in China. OBJECTIVES: The aims of this study were to translate BCSES into Chinese and assess its psychometric properties among Chinese patients. METHODS: In phase 1, the translation of BCSES closely followed the Principles of Good Practices. In phase 2, data on reliability and validity were evaluated in terms of internal consistency, item-total correlations, test-retest reliability, criterion validity, and construct validity. A total sample of 630 native Chinese-speaking patients from 5 hospitals in China participated, including a pilot sample of 182 and a validation sample of 448. RESULTS: Minor modifications in 5 items were recommended after translation. Both exploratory and confirmatory factor analyses suggested a 2-factor structure was more ideal than the original 1-factor model. Cronbach's α coefficient for the Chinese version of BCSES was .82, intraclass correlation coefficient was 0.97, and item-total correlations were from 0.61 to 0.76. CONCLUSIONS: The Chinese version of BCSES appears to be culturally appropriate, reliable, and valid for assessing self-efficacy among patients with breast cancer in China. IMPLICATION FOR PRACTICE: The Chinese version of BCSES could help measure the breast cancer patients' self-efficacy and provide evidence to develop culturally sensitive interventions for Chinese patients.

mHealth Supportive Care Intervention for Parents of Children With Acute Lymphoblastic Leukemia: Quasi-Experimental Pre- and Postdesign Study.

BACKGROUND: Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Caring for children with ALL is challenging for parents. A mobile health (mHealth) supportive care intervention was developed to meet parents' needs. OBJECTIVE: This study aims to evaluate the potential effectiveness of this mHealth supportive care intervention on emotional distress, social support, care burden, uncertainty in illness, quality of life, and knowledge. METHODS: We conducted a quasi-experimental pre- and postdesign study from June 2015 to January 2016. In total, 101 parents were enrolled in the study, with 50 in the observation group and 51 in the intervention group. Parents in the observation group received the standard health education and were observed for 3 months. Parents in the intervention group received the mHealth supportive care intervention, in addition to the standard health education. The intervention consisted of 2 parts-an Android smartphone app "Care Assistant (CA)" and a WeChat Official Account. The CA with 8 modules (Personal Information, Treatment Tracking, Family Care, Financial and Social Assistance, Knowledge Center, Self- Assessment Questionnaires, Interactive Platform, and Reminders) was the main intervention tool, whereas the WeChat Official Account was supplementary to update information and realize interaction between parents and health care providers. Data of parents' social support, anxiety, depression, care burden, uncertainty in illness, quality of life, their existing knowledge of ALL and care, and knowledge need were collected before and after the 3-month study period in both groups. For the intervention group, parents' experience of receiving the intervention was also collected through individual interviews. RESULTS: Overall, 43 parents in the observation group and 49 in the intervention group completed the study. Results found that the intervention reduced parents' anxiety (Dint(Post-Pre)=-7.0 [SD 13.1], Dobs(Post-Pre)=-0.4 [SD 15.8], t90=-2.200, P=.03) and uncertainty in illness (Dint(Post-Pre)=-25.0 [SD 8.2], Dobs(Post-Pre)=-19.8 [SD 10.1], t90=-2.761, P=.01), improved parents' social function (Dint(Post-Pre)=9.0 [SD 32.8], Dobs(Post-Pre)=-7.5 [SD 30.3], t90=2.494, P=.01), increased parents' knowledge of ALL and care (Dint(Post-Pre)=28.4 [SD 12.4], Dobs(Post-Pre)=17.2 [SD 11.9], t90=4.407, P<.001), and decreased their need for knowledge (Dint(Post-Pre)=-9.9 [SD 11.6], Dobs(Post-Pre)=-1.9 [SD 6.4], t90=-4.112, P<.001). Qualitative results showed that parents were satisfied with the intervention and their role in the caregiving process. CONCLUSIONS: The mHealth intervention in supporting parents of children with ALL is effective. This study is informative for other future studies on providing mHealth supportive care for parents of children with cancer.
