“…In the present study, we aim to evaluate the clinical‐ and cost‐effectiveness of Intensive Short‐Term Dynamic Psychotherapy (ISTDP; Davanloo, , ; Abbass, ) for patients with GAD. ISTDP is an emotion‐focused, experiential psychodynamic treatment model with a growing evidence base (Abbass, Town, & Driessen, ; Lilliengren, Johansson, Lindqvist, Mechler, & Andersson, ; Town & Driessen, ). Previous studies have indicated that ISTDP may be effective in complex psychiatric conditions, such as personality disorders (e.g., Abbass, Sheldon, Gyra, & Kalpin, ; Solbakken & Abbass, ), treatment resistant depression (Town, Abbass, Stride, & Bernier, ) and medically unexplained symptoms (Abbass et al, ; Chavooshi, Mohammadkhani, & Dolatshahee, ), all of which overlap considerably with GAD.…”
