This paper presents the development and validation of a new assessment tool for qualitative research articles, which could assess trustworthiness of qualitative research articles as defined by Guba and at the same time aid clinicians in their assessment. Background.  There are more than 100 sets of proposals for quality criteria for qualitative research. However, we are not aware of an assessment tool that is validated and applicable, not only for researchers but also for clinicians with different levels of training and experience in reading research articles.
