Study designs

[Scooter12]

Can anyone tell me what the methodology is for these three articles?

 

For example, quantitative-correlational etc

What do you think and why?

So far I've got...

 

1: Qualitative-longitudinal (study was conducted at one month and three months post stroke - it may be quantitative though?)

 

2: Quantitative-cross-sectional (study was conducted at a specific point in time)

 

3: Quantitative-correlational (there was a relationship among variables)

I couldn't see anything in the first to suggest it's qualitative (but i just looked at the abstract and data collection section). What makes you think so?

 

The main outcome is eating difficulty assessed by the Minimal Eating Observation Form - I. While this may be subjective (its intra and inter-rater reliability and its validity should be explored), it is an attempt to quantify eating difficulties and so is primarily quantitative research.

 

I agree it is longitudinal, you might want to add that it is observational as it is possible, though rare, to have have randomised longitudinal studies.

Thank you for your reply. I very much appreciate it. I believe I was looking at the subjectivity, however I can now see it is definitely quantitative. Do you feel I am on the right track for the others?

Second one, i agree. I'm not too sure about the third one: i'd have to read the whole thing but i don't have time. Safe to say that it is quantitative and observational though.

 

There are many nuances to study design in clinical research each with its own name. Don't worry about trying to learn all these names: learn to get a general idea of what the researchers were trying to do, and whether they were rigorous towards that end.
