Qualitative Nodes

Node	Example
Attitudes: Attitudes refer to a thought, belief, or statement that a therapist has towards evidence-based practices, CBT, or the Coping Cat.	“Prior to training, I really felt that the relaxation component took priority over CBT aspects, and I feel differently about that now. I do feel that the CBT is crucial”
Practice change: A statement that refers to a change in practice following training (i.e., doing things differently than before). Note this includes specifically adding or augmenting their practice with CBT.	(Did the way you work with your clients change?) “Um somewhat, not a lot, but I did use more of the relaxation only prior to training”
Barriers: Anything that might have gotten in the way in the implementation of CBT for child anxiety.	“A lot of them don't finish exposures”
Facilitators: Anything that might have helped/facilitated implementation of CBT for child anxiety.	“The coping cat program was very helpful in identifying kind of a structure to your therapy sessions and a lot of good ideas and activities”
Adaptation: Changes, modifications, or adaptation that the therapist makes to make CBT fit their practice, setting, or client population better.	“..or kids with autism, I use a lot of visual support because they are very visual learned, so we may write a social story about how to handle different situations and they read it immediately, and we have little visual supports like a little book marker”
Organizational factors: Anything related to their organizational setting that impacts how they implement CBT for child anxiety (i.e., administrative support, champion leader, not enough resources).	“A barrier is...kids having to leave class, or being away from the teachers setting, sometimes you are going to run into teachers who are not going to be supportive”
Self-efficacy: Therapist's confidence in their own ability to deliver CBT for child anxiety.	“I feel very confident in using CBT to treat anxiety for adults and adolescents”
Eclecticism: Therapist usage of a variety of treatment modalities (e.g., CBT plus family therapy, psychodynamicism, play therapy).	“I guess there are some psychodynamic principles that get engrained in some longstanding complex cases, but I would almost entirely identify myself as CBT”
Client factors: Anything that pertains to the client and/or their family (i.e., comorbidity, motivation, resistance) that may have impacted implementation of evidence-based practice	“We would start the exposures and they would feel like they were so much better and they wouldn't want to go all the way up the ladder”
Evidence-based practice language: “Buzzwords” that suggest that the therapist is knowledgeable about evidence-based practices more generally (not just related to CBT for child anxiety)	“Ultimately, it came down to prolonged exposure as the part of the mechanism of change”
Treatment factors: Anything that is specific to the treatment modality being used (i.e., CBT for child anxiety and/or Coping Cat)	“In vivo exposures...learning thoughts and coming up with alternative thoughts”
Consultation: When they discuss the consultation provided through the study	“I actually liked the consultation calls”

Note. CBT = cognitive-behavioral therapy
