Birth Attitudies Survey
1. When calculating the average of each set of structure set, it is reasonable to give each question of the set the same weight? i.e., some question may better reflect the attitude towards this set of questions.
2. From the attached article, maybe we can use the Cronbach's alpha to test whether the questions within each set are related to each other. Then what is the appropriate sample size to calculate this coefficient?
3. What is the cut-off numerical score which distinguish the overall attitude (disagree, agree, no opinion maybe) for each set of questions? Is chi-squared helpful here?
1. They say they intend to compare provider groups. Do you they compare these groups in each of 15 areas or just take a average of these 15 areas? Hear taking a simple average might lead to a misleading conclusion.
2. In the end, they talk about validty of their survey. I'm quite confused about the concept "validity" here. Does it mean that they hope to prove that this survey indeed reflects their real attitude towards surgical delivery?
3. Are the participants be able to distinguish the seven possibilities listed in the questionnaire? When I fill in such questionnaires, I feel so confused about disagree and strongly disagree.
1. By using the average of these scores(i.e agree, disagree, and so on..),, is it would be realistic to valiadate this survey ?
2. How could they identify the groupings by using the correlation structure of the these categogies avarage scores ? I think, sometimes it is difficult to distinguish among agree, strongly agree and mild agree ?
3. Besides these two set of questions, is it possible to add some quantitative measurements ? I think, that quantitative measurements would be beneficial to make a concrete decision about the safety of child-birth.
