The long road to routine care: piloting the digital mental health intervention for PTSD "Radius Grow" in a psychiatric residential setting.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhile psychotherapeutic interventions for Post Traumatic Stress Disorder (PTSD) are effective, transfer to everyday life is challenged by a shift from treatment setting to the patients' living environment. Adding digital components to the treatment (Blended Care, BC) may support autonomous completion of therapeutic tasks and facilitate transfer but has not been studied in residential treatment settings.
objectiveThe present study explores the implementation, usability, and preliminary effectiveness of a BC approach for PTSD treatment in a non-acute residential hospital setting. Clinician and patient perspectives are considered.
methods36 patients participated in a two-group quasi-experimental design (intervention vs. control) with three measurements (admission, discharge, three-month follow-up). Face-to-face trauma-focused CBT was offered in both groups, complemented by a BC software in the intervention group. Also, 16 clinicians participated in the study. We collected qualitative data from semi-structured interviews, software usage-data, and psychometric questionnaire data from patients and clinicians.
resultsPatients reported high satisfaction with software usability; clinicians had varying opinions. Uptake was inconsistent on both sides. Capacity issues and an inaccurate definition of the intended use hampered implementation. Still, intensified collaboration and sustained engagement with treatment contents were identified as benefits of BC. Quantitative measures of symptom severity showed no significant between-group differences in exploratory analyses and no relation to software usage intensity.
conclusionsThis study confirms potentials and obstacles of BC to facilitate the therapeutic process in the residential treatment of PTSD. It also emphasizes the importance of a concise concept for the coordination of digital and face-to-face components to ensure sufficient uptake and raise clinical effectiveness.
