As a counselor of any type, what value do whole-group instructional formats have for delivering psycho-educational content to individuals who could benefit form the content?

I have found delivering this content to groups to be quite effective.

It is an effective format, but does require supplementing with 1:1 or small group processing of the information.

I do not prefer this format for delivering content.

I only have limited experience delivering content or interventions to larger groups.

None of these options apply to my experiences as a counselor.
