2.0	Stage 2 screening
2.1	Assessment of family readiness or parental concern	Lengthening/extending	Int: So, how much time do families usually need between getting the BITSEA score and STAT?

2.2	Provider familiarity and ability to score BITSEA/POSI	Shortening	And if it is concerning…we know right away. And usually by looking at them, since I’ve a done of them, I can kind of see if they’re concerning or not, so we can talk about this, I usually talk about the STAT right then and there…would you be interested in further following this up if there is a concern?	3	0	0
2.3	Whether service coordinator is also Stage 2 administrator	Lengthening/extending	Yeah, with my families it’s a little bit different because I’m on the team so it tends to be more a little bit faster I think for people that are certified to do the STAT just because we can have our next visit be the STAT.	1	1	2
2.4	Availability of STAT administrators	Lengthening/extending	Int: if they decide to go onto the STAT, how long does that typically take? Like how long to schedule? Resp: It kind of has depended on just like availability of people that who are trained in it.”	0	3	0
