Description of Raw Themes and Subthemes

		Admin	Provider	Client
THEME: Knowledge and beliefs (Knowledge/personal opinions about anxiety disorders and their treatment)
Knowledge	Knowledge (e.g. treatment names) regarding anxiety disorders and treatment.	1/6	2/4	1/2	“I like to go to the ABCD worksheet- not sure what they stand for- but the activating event and go through the behaviors, thoughts, feelings and how they all affect each other.”
CBT-specific knowledge	Knowledge (e.g. intervention descriptions) about CBT.	1/6	3/4	1/2	“…I’ve never been trained in it and don’t know a lot about it…”
Beliefs	Positive/negative perceptions about anxiety disorders and treatment.	5/6	4/4	2/2	“I think that any EBP is helpful. I think that having a structure and being able to say it’s something that’s been proven to work is helpful…”
CBT-specific beliefs	Positive/negative perceptions about CBT.	1/6	3/4	0/2	“I lost a lot of faith in the cognitive portion for really bad anxiety.”
THEME: Barriers (to accessing or offering evidence-based anxiety treatment)
Client-level	Competing priorities, client characteristics, logistical issues.	5/6	4/4	2/2	“…yes, maybe 90% of our clients have anxiety, but the homelessness issue, the depression, the suicidality- that’s what we need to focus on.”
Provider-level	Competence, discomfort, training/supervision, time.	3/6	3/4	0/2	“I definitely feel like I need more ongoing supervision, I think I got the basics down from the coursework, but definitely ongoing supervision and maybe a consultation…”
Organization al-level	Training/supervision issues, staff competence.	5/6	3/4	2/2	“…the social workers, it varies. So right now I think we have one who’s pretty confident in delivering CBT that we would be speaking the same language. The other one I think is more eclectic.”
System-level	Level-of-care issues, funding/reimbursement constraints.	6/6	1/4	0/2	“…I’ve always seen that one of the larger problems is that the way insurance companies pay really dictates the treatment in a lot of ways.”
THEME: Facilitators/solutions (for accessing and benefiting from evidence-based anxiety treatment)
Client-level	Motivation, attendance, therapeutic relationship.	0/6	3/4	2/2	“I like being able to come and talk to my therapist, because he doesn’t judge me. I know there’s confidentiality- I feel free.”
Provider-level	Competence, therapeutic relationship.	1/6	3/4	1/2	“Of course you develop a rapport with the patient, I think that’s really important before you really talk to them about exposure.”
Organizational-level	Training/supervision, caseload size, guidelines.	5/6	2/4	0/2	“I think it was a good enough training to get you started and get things off the ground and start trying CBT. I would feel that if there weren’t the consultation calls and we have a monthly group here – without that I wouldn’t feel as willing to keep trying CBT interventions.”
System-level	Funding/reimbursement structures, leadership, supportive policies.	5/6	1/4	0/2	“…unless there is an advocate for it or a compelling regulatory reason, people often don’t do it.”
