The self-management instrument for breast cancer patients undergoing adjuvant therapy: Development and psychometric testing using the COSMIN methodology.

Objective: This study aims to develop and test the self-management instrument for breast cancer patients undergoing adjuvant therapy (SMAT-B). Methods: After a qualitative interview with 29 patients and two rounds of Delphi expert consultation with 15 experts, 49 items were initially generated. Before item reduction, another structured interview was conducted for content validity. Item analysis and exploratory factor analysis (n â€‹= â€‹377) were used for item reduction. After that, internal consistency, split-half reliability, test-retest reliability (n â€‹= â€‹30), measurement error, construct validity, and structural validity (n â€‹= â€‹342) were preliminarily evaluated using the COnsesus-based Standards for the selection of health Measurements INstruments guidelines. Results: The final version of SMAT-B includes 7 dimensions and 31 items after item reduction. The testing results suggested that SMAT-B had good internal consistency (Total Cronbach's α â€‹= â€‹0.952), good split-half reliability (Spearman-Brown coefficient â€‹= â€‹0.904), good stability (Total intraclass correlation coefficient = â€‹0.797), acceptable measurement error (SEM â€‹= â€‹5.28), and acceptable construct validity (Standardized root mean square residual â€‹= â€‹0.055). The hypotheses of construct validity were all verified to a certain extent (r â€‹> â€‹0.20, P â€‹< â€‹0.01). Conclusions: The 31-item SMAT-B, developed in interviews with patients and consultation with experts, demonstrated good psychometric properties and can be recommended for researchers and clinicians for further validity testing and evaluation of the self-management ability of breast cancer patients.

Psychometric properties of self-reported measures of self-management for chronic heart failure patients: a systematic review.

AIMS: The aim of this study is to identify and assess the psychometric properties of patient-reported outcome measures (PROMs) of self-management for chronic heart failure (CHF) patients. METHODS AND RESULTS: Eleven databases and two websites were searched from the inception to 1 June 2022. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias checklist was used to assess the methodological quality. The COSMIN criteria were used to rate and summarize the psychometric properties of each PROM. The modified Grading of Recommendation Assessment, Development, and Evaluation was used to assess the certainty of evidence. In total, 43 studies reported on the psychometric properties of 11 PROMs. Structural validity and internal consistency were the parameters evaluated most frequently. Limited information was identified on hypotheses testing for construct validity, reliability, criterion validity, and responsiveness. No data regarding measurement error and cross-cultural validity/measurement invariance were achieved. High-quality evidence on psychometric properties was provided for Self-care of Heart Failure Index (SCHFI) v6.2, SCHFI v7.2, and European Heart Failure Self-care Behavior Scale 9-item (EHFScBS-9). CONCLUSION: Based on the findings from the included studies, SCHFI v6.2, SCHFI v7.2, and EHFScBS-9 could be recommended to evaluate self-management for CHF patients. Further studies are necessary to evaluate more psychometric properties, such as measurement error, cross-cultural validity/measurement invariance, responsiveness, and criterion validity, and carefully evaluate the content validity.

Self-Management About Adjuvant Therapy in Breast Cancer Survivors: A Qualitative Study.

Objective: This study aims to describe the experience and connotations of self-management about adjuvant therapy (AT) in Chinese breast cancer survivors (BCS) and explore possible factors that affect their self-management level. Methods: Semi-structured interviews were conducted in postoperative BCS undergoing AT using a qualitative description method. The conceptual structure and connotations were extracted after researchers collected and coded interview transcripts. Results: After interviewing 29 patients, the conceptual framework of self-management in BCS during AT was optimized with three major themes: medical-related, emotion, and role management. Medical-related management includes AT-related adverse reactions; medical cooperation and knowledge acquisition; recovery and protection of affected limb; medical compliance; body image; sexual function and fertility; healthy lifestyle; catheter daily protection; and AT-related financial burdens. Emotion management includes recognition, prevention, and regulation of negative emotions. Role management consists of three aspects: family role, social role, and work role. Conclusion: The conceptual structure and connotations formed in this study can help researchers to evaluate and intervene in the self-management ability of BCS during AT, so as to formulate the best model of care to improve their quality of life and clinical outcomes.
