Although the results do not allow firm conclusions to be drawn, it seems that investigating factors such as communication modality and
pretreatment symptom severity as moderators of the therapeutic relationship might be a fruitful direction of research.
Change ratios revealed that PTSD
symptom severity as measured by the CAPS decreased almost 3 times more in CBCT from
pretreatment to posttreatment compared with the wait list (CBCT: mean change, − 35.42 [95 % CI, − 47.84 to − 23.00]; wait list: mean change, − 12.20 [95 % CI, − 21.51 to − 2.89]; mean change difference, − 23.21 [95 % CI, − 37.87 to − 8.55]-RRB- and patient - reported relationship satisfaction, as measured by the DAS, increased more than 4times more in CBCT compared with the wait list (CBCT: mean change, 12.22 [95 % CI, 5.72 - 18.72]; wait list: mean change, 2.79 [95 % CI, − 3.95 to 9.53]; mean change difference, 9.43 [95 % CI, 0.04 - 18.83]-RRB-.
Children with a higher level of
pretreatment severity need greater decreases in
symptoms to reach a subthreshold level of
symptoms, therefore we also examined pre to posttreatment Reliable Change.
