Power analysis for cronach's alpha

#1
Is n=52 an appropriately powered sample for a Cronbach's alpha analysis across five different items? If so, what effect size would this be powered for?

Any help/resources would be appreciated!

Thanks for your reply. Technically no - but my hypothesis is that several memory items will demonstrate satisfactory levels of stability (relating to the assumption that memory is an individual difference). Is there some kind of analysis that needs to be done to demonstrate that this is an appropriate sample size to examine this hypothesis?

According to a quick web search, you might want to insert different sample sizes and compute the according confidence intervals for example here, or you can use this source. The reference is available here.

With kind regards
