A self-care self-efficacy scale (SCES) in COPD was also developed by the same team of researchers to measure self-efficacy, which has a powerful influence on self-care in chronic diseases. The 7-items scale presents two factors that describe the confidence of people with COPD in their ability to adhere to prescriptions and to manage symptoms.
The SC-COPDI and COPD-SCES showed good validity and reliability in an Italian sample [Matarese, M., Clari, M., De Marinis, M. G., Barbaranelli, C., Ivziku, D., Piredda, M., & Riegel, B. (2019). The Self-Care in Chronic Obstructive Pulmonary Disease Inventory: Development and Psychometric Evaluation. Evaluation & the Health Professions. doi: 10.1177/0163278719856660].
Scoring for each of the three self-care scales (Section A= self-care maintenance scale; Section B= self-care monitoring scale; Section C=self-care management scale) and for the SCES-COPD is calculated through the following formula: (mean-1)*25 in order to standardize to 100 the scores. As not-applicable (NA) answers are possible, the mean is calculated only for the given answers. The item 9 is not computed in the score.
