“…The Delphi technique is a systematic and interactive method to achieve a general agreement or convergence of opinions on a particular topic 51 . It has proven to be a reliable method to develop new concepts 52 and establish consensus across a range of subject areas, 53 including several in the field of HL measurements 19,54–56 . In the present study, two phases were conducted: (a) item development of HLS‐HK by evidence synthesis using a deductive method and (b) content validity of HLS‐HK employing a modified e‐Delphi survey with healthcare consumers and providers.…”

Introduction Health literacy (HL) refers to individuals' abilities to process and use health information to promote health. This study aimed to develop the first HL measurement tool for the Chinese Hong Kong population. Methods A two‐phase methodology was adopted. In Phase I , evidence synthesis with a deductive method was conducted to formulate the item list from the literature. In Phase II , a modified e‐Delphi survey was conducted among stakeholders (i.e., healthcare providers and healthcare consumers) to confirm the content validity of the item list. The stakeholders were invited to rate the relevance of each draft item on a 4‐point scale and provide suggestions for revisions, removal or adding new items. Results In Phase I , a total of 34 items covering functional, interactive and critical HL were generated. In Phase II , to obtain a balanced view from experts and laypeople, healthcare professionals ( n = 12) and consumers ( n = 12) were invited to participate in the Delphi panel. The response rates of the three rounds were 100%. After the third round, the consensus was reached for 31 items, and no further comments for adding or revising items were received. All items exhibited excellent content validity (item content validity index: 0.79–1.00; K* : 0.74–1.00). Conclusions A Health Literacy Scale for Hong Kong was developed. Compared with existing HL scales, the scale fully operationalized the skills involved in functional, interactive and critical HL. The Delphi study shows evidence supporting the high content validity of all items in the scale. In future studies, these items should undergo rigorous testing to examine their psychometric properties in our target population groups. By illuminating the details in the development process, this paper provides a deeper understanding of the scale's scope and limitations for others who are interested in using this tool. Patient or Public Contribution Public as healthcare consumers, in addition to healthcare providers, were involved in developing a new HL scale for this study. The input from the public contributed to examining the scale's content validity by judging whether all items reflected the skills that they need to find and use health‐related information in their daily life.

Background: Post-ICU syndrome has not been paid enough attention in Chinese medical institutions. Due to the large population base in my country, the number of people with post-ICU syndrome is also large, which has a great impact on the quality of life of patients in the later period.Objective To develop and verify ICU nurses' knowledge, attitude and practice questionnaire on post-ICU syndrome in critically ill patients, to provide a basis for the investigation of post-ICU syndrome status.Methods Using the principle of Knowledge, Attitude and Practice (KAP), a questionnaire item database was created through literature review and semi-structured interviews. The questionnaire was modified by Delphi expert correspondence method and pre-investigation. 451 ICU nurses were selected for formal investigation, and the reliability of the questionnaire was evaluated degree test.Results A questionnaire of knowledge, attitude, and practice of ICU nurses on post-ICU syndrome in critically ill patients was formed, in which the number of items in the three dimensions of knowledge, attitude, and practice were 11, 7, and 13, respectively. The Pearson correlation coefficient between dimensions and the total score of the questionnaire ranged from 0.526 to 0.860, and the correlation coefficients between items and dimensions ranged from 0.517 to 0.921 (P＜0.001). Item content validity (I-CVI) ranged from 0.867 to 1, and questionnaire content validity (S-CVI) =0.989. Four common factors were extracted by exploratory factor analysis, and the cumulative variance explanation rate was 76.214%. Confirmatory factor analysis: Chi-square ratio of degrees of freedom (χ2/df) =2.789, RMSEA=0.077, RMR=0.048, GFI=0.947, CFI=0.922, NFI=0.943, IFI=0.922, TLI=0.915. The Cronbach's alpha coefficients of the questionnaire and dimension were 0.948, 0.976, 0.966, 0.910, split-half reliability = 0.951, and test-retest reliability = 0.927.Conclusion The reliability and validity of the questionnaire meets the requirements of questionnaire preparation, and can reflect the knowledge, belief, and behavior of ICU nurses in post-ICU syndrome.
