Fletcher, 1991 & 1992
The WBTH scale is a 95-item self-report inventory. The questions in this scale exactly parallel the questions in the Childhood PTSD Interview and can be used as a complement to the interview. It includes 63 DSM-IV symptom items (3 - 6 per symptom) and 32 associated symptom items (2 - 5 questions per associated symptom).
Items are rated on a 3-point frequency scale ("Never", "Some", "Lots"). The WBTH yields a categorical diagnosis of PTSD as well as a continuous severity score (a scoring system template is provided with the scale). It has a third-grade reading level and includes a parent report version. It is appropriate for use in either a research or clinical setting.
