Using a questionnaire, I analyse the affective well-being after three different dance lessons at three points in time (before, during, after) in the same subjects. Background: the social interaction is changed in each of the three dance lessons, while movements, sequences, etc. are kept the same.
On the one hand, I would like to investigate whether well-being generally increases as a result of dancing, as well as whether well-being changes differently depending on the dance lesson content (social interactions). For this I would use a repeated measures ANOVA.
I would also like to investigate whether the experience of competence surveyed has an influence on the change in well-being (co-variate). I have read that an ANCOVA obviously does not work with a repeated measures ANOVA. Which statistical analysis should I use instead to analyse the influence of a co-variate (or moderator)? Thank you very much for your help

Hi,
Run a repeated measures ANCOVA. It analyses changes in well-being across time points, considering both social interaction in the dance lesson and the influence of competence.
Hope this helps.
IYH Dear Sabrina Jud
IMHO use a Multivariate Analysis of Covariance (MANCOVA) which allows you to examine the effect of one or more categorical independent variables (dance lessons) and one or more continuous covariates (experience of competence) on one or more dependent variables (well-being).
In your case, you would have three levels of the categorical independent variable (three dance lessons) and one continuous covariate (experience of competence). Your dependent variables would be the well-being scores at the three different time points.
By performing a MANCOVA, you can determine the effect of the dance lessons on well-being while controlling for the influence of the experience of competence. This will help you understand how the different social interactions in the dance lessons impact well-being, as well as how the experience of competence affects these changes.

Hello Sabrina Jud. Given your description, and assuming that affective well being is measured in such a way that it is both sensible and defensible to use means and SDs for descriptive purposes, I think you should consider using a multilevel model, with the repeated measurements at level 1 and subjects at level 2. If you say what software you use, someone may be able to direct you to relevant examples using that software. HTH.
