There was only one author, who was seemingly responsible for all aspects of the study (recruitment, randomisation, assessment, therapy, analysis). The author had conceived the therapy that was being evaluated, based on a theory of PTSD they had previously formulated. The author acknowledged "this study must be replicated with a more rigorous design that fulfills all of the golden criteria for a randomized controlled study." |
| Blinding of participants and personnel (performance bias)
All outcomes |
High risk |
Comment: Participants were aware of their allocation. |
| Blinding of outcome assessment (detection bias)
All outcomes |
High risk |
Quote: "The assessor was both the therapist and the author of the current study." |
