I was wondering where this assessment sheet came from. Does it have any psychometrics attached? Any scoring criteria? And, why is it being produced as a handout for teachers? Anyone teaching this stuff should know it and not need a guide. If it is being used, or going to be used as an actual assessment measure then there need to be limits stated on who can use it, and some clear description of the psychometric properties.
This is serious stuff as the assessment of PTSD is a serious, and sensitive business.
