Validation of the Energy Conservation Strategies Inventory (ECSI)

Abstract

The good psychometric properties of the ECSI instrument show that it may be useful for measuring the frequency of energy conservation strategies used by cancer patients.

Patient‐reported assessment of self‐management strategies of health in cancer patients: development and validation of the Smart Management Strategy for Health Assessment Tool (SAT)

“…Finally, 300 subjects responded to the whole set of questionnaires, which satisfied the ratios of participants to items for each questionnaire for validation of an assessment tool. The validation considers 10 rules, which suggests a ratio of about 5–10 subjects per item . Because each SAT set has 30–33 items, 165–330 subjects would be appropriate for the validation process.…”

“…Finally, a total of 101 items for the three sets of strategies were compiled: 30 items for SAT‐C, 35 for SAT‐P, and 36 for SAT‐I. These selection rules for decisions were adapted in the questionnaire module guidelines developed by the European Organization for Research and Treatment of Cancer Quality‐of‐Life Group .…”
