ELSA uses the same respondents as the HSE, and therefore we are confident that our results are not contaminated by under-reporting.
Using the same scale, respondents then rated how much 'each message would encourage them to use the stairs' (motivation rating).
Standardised item alpha = 0.58 Test-retest reliability is the degree of agreement between two measurements taken at two different points in time using the same scale and with the same respondents; this provides an estimation of the degree to which the results are reproducible [ 14].
Discriminant analysis indicated that the language used by male and female respondents in the male guise differed from that used by the same respondents in the female guise, supporting communicators' consistent gender-linked language schemata, and stereotypes, and the new process model.
According to Rapkin & Schwartz QoLL appraisal model, patients are assumed to answer all individual questionnaire items at one time point using the same cognitive processes, e.g. respondents use the same reference group(s) in answering all items of an entire questionnaire.
For example, no negatively worded items were used, so response-set bias may result (i.e., respondents using the same response for all categories).
To ensure item clarity, the questionnaire was tested in a convenience sample of 24 respondents using the same method as for the data collection - telephone interviews.
The anchoring vignette serves to describe a concrete level in a given health domain that the respondent evaluates using the same question and response categories used for self-assessment on that domain.
These respondents were recruited using the same sampling design as in Wave 1.
Some respondents stated that using the same grading system improves consistency, transparency, and reproducibility, while others stated that they are fundamentally different types of decisions and evidence, requiring different grading systems.
