A public health analyst is checking whether figures from two local datasets are close to the estimates for the UK as a whole.
| Dataset | Group | Total number | Relevant outcome | Number with the outcome |
|---|---|---|---|---|
| Community survey | Adults interviewed in one UK county | 1,200 | Met the criteria for clinical depression at some point in their life | 132 |
| NHS therapy records | People who completed a course of talking therapy for depression | 240 | Recorded as recovered at the end of the course | 126 |
Calculate the lifetime prevalence of clinical depression in the community survey as a percentage. Show your working and give your answer to one decimal place.
Calculate the recovery rate among the people who completed NHS talking therapy as a percentage. Show your working and give your answer to one decimal place.
Using your own knowledge, state the UK estimate for lifetime prevalence of clinical depression and the UK estimate for recovery after completing NHS talking therapy. Compare each of your answers to (a) and (b) with the matching UK estimate.
