Abstract Background Although there is good evidence to support the effectiveness of cognitive behavioral therapy (CBT) for the outpatient treatment of adolescent major depressive disorder (MDD), evidence-based manuals for the inpatient setting are lacking. This pilot study sought to (i) adapt an existing CBT manual (treatment of adolescent depression; TADS) to an inpatient setting (TADS-in), (ii) test its effectiveness at symptom reduction and remission of MDD in a pre-post design, and (iii) assess the strengths and limitations of the manual via a focus-group with clinicians. Methods Twenty nine adolescents aged 12–17 years with a primary ICD-10 diagnosis of MDD being treated as inpatients at a psychiatric clinic were included. Embedded in the regular inpatient treatment course (8 weeks), patients received 12 sessions of the TADS-in manual. Quantitative assessment of symptom reduction and remission of MDD was conducted using a non-controlled pre-post design. The quantitative results were supplemented by a focus group with participating psychotherapists. Results Of the 29 patients included in the study at the beginning, 19 (65.5%) remained in the study at week 8. Symptoms of depression were statistically significantly lower at the end of treatment than at baseline according to self- (d = 1.38; mean change = 19.88; 95% CI = 12.48–27.28) and other reports (d = 0.64, mean change = 0.35; 95% CI = 0.08–0.62). Clinicians ratings of improvement (CGI-I) suggested that at the end of treatment, 15.8% were very much improved, 68.4% much improved, and 15.8% were minimally improved. According to diagnostic interviews with patients conducted at the end of treatment, 73.3% were in remission. The qualitative analysis showed that on the whole, the TADS-in manual is suitable for the inpatient setting. However, clinicians believed the effectiveness of TADS-in was limited by patient comorbidity and the fact that the inpatients were unable to practice incorporating techniques learnt into everyday life. Conclusions This study is the first to adapt the TADS manual to the inpatient setting. The sample of depressed adolescents showed reduced symptomology following treatment, although these findings require replicating in a randomized controlled trial before effects can be attributed to the TADS-in manual specifically. This pilot study informs further development of the manual as well as representing an important first step in the evaluation of the inpatient treatment of adolescent depression. The study was retrospectively registered (DRKS00017308) and received no external funding.
