Development and Validation of a Holistically Based Follow-Up Pain Assessment Diary Leading to Holistic Nursing for Patients with Cancer Pain in Sri Lanka.

Abstract

Purpose of the study: The study aimed to develop and validate a holistically based follow-up pain assessment diary for patients with cancer pain in Sri Lanka. Design of the study: Mixed-method design adapted. Methods used: Developing a pain diary and testing its psychometric qualities were done in two phases. Comprehensive literature research and qualitative semistructured interviews with patients, clinical, and subject specialists created the pain diary items. Content, face, construct, criterion validity, and reliability were evaluated. Findings: The essential domains to be assessed were identified under six main categories; pain and related characteristics, physical, psychological, social, spiritual, and financial aspects. The average variance extracted from the subscales "Influence on daily life," "Gastric disturbances," and "Pain intensity" were 0.526, 0.562, and 0.696, respectively. The heterotrait-monotrait criterion values between subscales were from 0.691 to 0.44, which was lower than the threshold. Good to excellent correlation coefficients were demonstrated with the scores of reference tools. Cronbach's alpha was computed for each subscale and ranged from 0.75 to 0.92 and composite reliability from 0.921 to 0.826. Conclusions: Pain diary is a reliable and valid instrument for follow-up assessment of holistic pain experience enabling holistic nursing among patients with cancer pain in Sri Lanka.
