Global comfort scale: construção e validação de conteúdo

Introduction: Comfort is an indicator of good practice, which is why its promotion and assessment are essential, regardless of the person's health/illness condition. Objective: To construct and validate the content of the Global Comfort Scale. Methods: Methodological study. Content validation was carried out using the e-Delphi technique with experts who commented on clarity, pertinence, and relevance. The content validity of the items was checked using the IVC-I and the scale using the IVC-S. The pre-test was carried out by talking to 20 members of the target population (adults or elderly people, healthy or suffering from illness), and the final version of the instrument was applied to 43 participants. Results: 12 experts assessed the content of the instrument's items using a Likert-type response scale, resulting in a final scale made up of 55 items with an acceptability criterion of over 0.80. A CVI-S of 0.97 was obtained for clarity, 0.90 for pertinence, and 0.93 for relevance, which confirms the validity of the content. In the spoken reflection, the participants had no difficulties or suggestions. The 43 participants had a good level of comfort with all the items. We found a Cronbach's alpha of 0.981 and Pearson correlation values of the item with the total scale without the item between 0.247 and 0.879. Conclusion: The instrument showed a good content validity index, followed at a later stage by psychometric validation.
