Questioning the Internal Validity: Randomisation : How were participants allocated to each group? Did a randomisation process taken place? Participants were randomly assigned to either intervention or control in a one-to-one ratio with a computer generated randomization list with a block size of 4 using REDCap p.
Comparability of groups: How similar were the groups? Eg age, sex, ethnicity — is this made clear? Table 1 p. The two groups were quite similar only big differences were Cholesterol and Diastolic blood pressure p value of under 0.
Blinding none, single, double or triple : Who was not aware of which group a patient was in? eg nobody, only patient, patient and clinician, patient, clinician and researcher? Was it feasible for more blinding to have taken place? No mention if the researchers or those who weighed patients were blinded — they could have been. Equal Treatment of groups: Were both groups treated in the same way? At first until the intervention p. Then the interventions were very different p.
Weight watchers — 45 minutes activation, free weekly sessions plus access to an app; Your Game Plan — booklet and 15 mins. Attrition : What percentage of participants dropped out? Did this adversely affect one group? Has this been evaluated? Big difference so could have had an effect. Discussed in the limitations section p. Overall Internal Validity: does the research measure what it is supposed to be measuring? Yes, critical appraisal of quantitative research example essay using casp, it appears reasonable.
Questioning the External Validity: Attrition: Was everyone accounted for at the end of the study? Was any attempt made to contact drop-outs? No, there were drop-outs p. Yes, must have attempted to contact them as they give reasons for drop-out in Figure 1 p. Sampling Approach: How was the sample selected? Was it based on probability or non-probability?

Test re-test reliability correlation. Was the test repeated more than once? Were the same results received? Has a correlation coefficient been reported? Is it above 0. Yes, weighed at 6 and 12 months p — table 2. Not the same results, but this would not be expected as would aim for more weight loss. Correlation coefficient not mentioned. Validity of measurement tool.
Is it an established tool? If not what has been done to check if it is reliable? Pilot study? Expert panel? Literature review?
Criterion validity test against other tools : has a criterion validity comparison been carried out? Was the score above 0. Yes p. Pilot etc not needed as established tools. What is the overall reliability?
How consistent are the measurements? Good - appropriate tools used. Overall validity and reliability: Overall how valid and reliable is the paper? The study can only be compared with the Your Game Plan sessions, not the Diabetes Prevention Program DPP plan discussed at the beginning of the article.
