Liang, Shu-Yuan, Yates, Patsy, Edwards, Helen E., & Tsay, Shiow-Luan (2008) Development and initial evaluation of reliability and validity of the opioid-taking self-efficacy scale. Oncology Nursing Forum, 35(4), E62-E69.
Purpose/Objectives: To examine the reliability and validity of the Opioid-Taking Self-Efficacy Scale-Cancer (OTSES-CA).-----
Design: Survey of two separate samples.-----
Setting: Two teaching hospitals in the Taipei area of Taiwan.-----
Sample: 30 (stage 2, pilot study) and a second cohort of 92 (stage 3) outpatients who had been prescribed opioid analgesics for cancer-related pain.-----
Methods: A preliminary set of 35 items was developed from qualitative interviews to assess the key domains of self-efficacy. The scale properties were evaluated with the first sample using face validity, test-retest reliability, and Cronbach alpha. Construct validity using exploratory factor analysis and concurrent validity were evaluated with the second sample.-----
Main Research Variables: Opioid-taking self-efficacy.-----
Findings: An initial pilot study supported face validity and test-retest reliability with stability coefficients for the subscales of the OTSES-CA, ranging from 0.68 (taking analgesics according to schedule) to 0.82 (communicating about pain and taking analgesics). An exploratory factor analysis demonstrated the multidimensionality of the OTSES-CA. Four factors were identified: communicating about pain and analgesic-taking, tailoring the medication regimen, acquiring help, and managing treatment-related concerns. Cronbach alpha coefficients reached the 0.80 criterion for each of four subscales constructed from items loading on these factors. Significant correlations among the total score of the OTSES-CA and mean adherence rates, pain relief, and worst pain support the concurrent validity of the OTSES-CA.-----
Conclusions: The data provide preliminary evidence of acceptable psychometric properties for the OTSES-CA designed to measure patients' self-efficacy with taking opioids. Further validation is recommended to confirm the four dimensions of the construct.-----
Implications for Nursing: The OTSES-CA can be used in research and clinical settings to identify various impediments to opioid adherence.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
