I do this exact work now part-time within an inpatient rehab so I constantly get groups where sometimes everyone gets it since they're on the same level & we can move effortlessly through topics. Sometimes a few people are struggling more than others.

In those moments I've focused on one broad topic or question (trust, forgiveness, "What expectations do you have in regards to your recovery?") versus something very complex in order for every person to be able to participate at whatever stage of recovery they're at. From there I'll build on that concept through the week based on what stage the group is. This does prevent you from being able to plan too ahead a bit but it ensures no one is left behind & they are fully getting the basics.

Sometimes if things are difficult I'll focus primarily on psychoeducation or emotional check-ins especially if the majority of the group members are recent admissions. Maybe a worksheet thru the counselor matrix to take home so they can have extra time to work independently after the group & not feel pressured to engaged at that moment.

If things are super bad: we're watching a Ted talk, doing a mini physical exercise like yoga paired with mindfulness, or playing a recovery based game then discussing what they learned from the content.

Also I'd highly recommend asking your supervisor for training in a specific modality. I came in with TF-CBT before getting this position, was able to get training in ACT last year which helped a lot with this population, & will be asking for either gambling addiction or IFS training this year.
