Twenty-nine items were deleted and nine items were added in total, leaving 62 items to enter psychometric testing. Emphasis was placed upon retaining a sufficient number of items to represent each of the five themes identified. Following expert and patient refinement, two independent item pools were confirmed as suitable to enter psychometric testing. The first item pool contained 23 items asking respondents about their general attitudes toward health websites whilst the second item pool contained 39 items asking the respondent about their attitudes

Epigenetics Compound Library purchase toward a specific health website. All items have a five point response scale (Strongly disagree–Strongly agree). Establishing a robust evidence base for the use of health websites is becoming increasingly important given that patients routinely turn to the web for information and support. This research developed items which will inform a new measure to evaluate the health related effects of websites and create a standardized method to compare health websites. Items constructed were

checked Kinase Inhibitor Library for their applicability across long term conditions, health behaviors and carers and for websites featuring facts and figures, health experiences and discussion forums. This paper documents the steps taken to inform items that may be included in the e-Health Impact Questionnaire. A recent literature review [14] relating to the potential effects of seeing and sharing experiences online and a secondary data analysis of interviews relating Pomalidomide mw to experiences of health were used to generate a range of items. Five themes were identified as relevant to the impact of using health websites containing scientific

information and to websites containing experiential information: (1) Information, (2) feeling supported, (3) relationships with others, (4) experiencing health services, and (5) affecting behavior. Confirmatory data sources were used to triangulate the findings. Comparing themes to issues raised in the focus group transcripts and user panel forms provided more depth in relation to negative aspects of using the internet, for example, becoming isolated from society through the overuse of discussion forums or misdiagnosing symptoms. Using a range of sources to identify and confirm themes provided strong evidence for their inclusion in the item pool. After a period of item selection, the item pool was evaluated by experts in the area of e-health.
