The development of a behaviour questionnaire for stoma self-management for persons with bladder cancer and an ileal conduit

Development and preliminary validation of a PROS scale for Chinese bladder cancer patients with abdominal stoma

Bladder cancer is a common malignant tumor, and patients who have undergone radical cystectomy and urinary diversion require a lifelong abdominal stoma. This greatly affects their physiological, psychological, and social well-being. However, there is currently a lack of a self-assessment outcome scale specifically designed for bladder cancer patients with abdominal stomas. Therefore, we developed and validated a self-assessment outcome scale (PROS-BCAS) for Chinese bladder cancer patients with abdominal stomas. The scale was initially developed through literature research and expert consultation, and it comprised four dimensions: physiological, psychological, social, and treatment, with a total of 66 items. After item analysis, 44 items were retained. We collected scale data from 382 patients to examine its validity and reliability. The results showed that the PROS-BCAS scale had good content validity (S-CVI/Ave = 0.992), construct validity (KMO > 0.6), and discriminant validity (correlation coefficient 0.404-0.870). The Cronbach's alpha coefficients (0.801-0.954), test-retest reliability (0.778-0.956), and split-half reliability (0.896-0.977) all demonstrated good internal consistency for each dimension and the overall scale. The study demonstrated that the PROS-BCAS scale is a reliable and valid tool for accurately assessing the health-related quality of life of bladder cancer patients with abdominal stomas, providing reference for developing individualized clinical care plans.

Development and psychometric testing of burn inpatient nursing dependency assessment scale

AIMS

The aim was to develop and psychometrically test the burn inpatient nursing dependency assessment scale (BINDAS).

DESIGN

This was a scale development study.

METHODS

This study was conducted in four phases from November 2019 to November 2021. Items were generated and the initial scale was constructed in phase 1. The preliminary evaluation of items was conducted through expert reviews and a pilot study in phase 2. The scale, including item quality, reliability and validity, was validated with 420 individuals in phase 3. The translation of the scale from Chinese to English was performed in phase 4.

RESULTS

Content validity was satisfactory. Thirteen items were retained after item analysis, and three factors accounting for 73% of the total item variance were extracted through exploratory and confirmatory factor analyses. Predictive validity with nursing time spent with patients during 24 h was also estimated, with r = .66 (p < .01). Receiver operating characteristic analysis was conducted, and an area under the curve of the scale of 0.94 was obtained. Concurrent validity with Barthel index was estimated, with r = -.71 (p < .01). Cronbach's alpha coefficient for scale was .93, and the correlation between raters for total scores was .95.

CONCLUSION

Burn inpatient nursing dependency assessment scale is a psychometrically valid and reliable measurement instrument as well as objective other-rating scale with 12 items for scoring on a four-point scale (0, 1, 2 or 3) and 1 item for scoring on a two-point scale (0 or 2). BINDAS with 13 items was developed in this study. Nurses can give each patient a total score of 0-38. A high score indicates high nursing dependency. The 13-item scale consists of three factors: basic care need, physiological index, and psychology and adaptation.

IMPACT

This scale demonstrated satisfactory psychometric properties and can be used to evaluate patient dependency on nurses in burn units and optimize an individual's care plan to achieve efficient staff allocation.
