RESEARCH

Dr Siddaway is interested in conducting and supervising research that improves the understanding, prevention, assessment, and treatment of psychological problems. His research particularly focuses on suicide, nonsuicidal self-injury, trauma, and the conceptualisation of psychological problems. He has particular expertise in systematic reviews, meta-analysis, psychometrics, and scale development and validation.

Between 2014 and 2017, Dr Siddaway was awarded a prestigious MRC Clinical Research Training Fellowship. This research involved developing the two most comprehensive self-report questionnaires of suicide attempt and nonsuicidal self-injury/self-harm beliefs currently available. Dr Siddaway hopes that developing these new self-report scales will improve the understanding, prediction, and treatment of self-injurious behaviours, potentially saving lives. He is currently preparing a number of articles using data collected during this Fellowship.

Dr Siddaway has provided peer-reviews for ~40 journals, including top-tier outlets such as PNAS and The Lancet Psychiatry. He has been invited to grant review for the ESRC, act as external PhD examiner at two Universities, and been appointed to the Editorial Advisory Board of the Journal of Traumatic Stress for two terms (2017-2023). He has supervised six doctoral students, two masters students, and three research assistants. He has extensive teaching/training experience in clinical and academic settings and experience of public engagement. In 2015, he was interviewed regarding mindfulness based cognitive therapy for Radio 4’s All in the Mind because his 2013 article on this topic is one of the only published critiques of the quality of the research that has been conducted in this area. 

He is happy to receive enquiries from students seeking research supervision.
