What methods are used in research of firsthand experiences with online self-harming and suicidal behavior? A scoping...

Online self-harming and suicidal behavior is a novel and rapidly increasing phenomenon warranting comprehensive mapping of used research methods.

To identify and map how knowledge on online self-harming and suicidal behavior is gathered, including how data are collected e.g. questionnaires and interviews.

The review follows the Joanna Briggs Institute Manual for Scoping Reviews in tandem with Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. A keyword search of three electronic databases was conducted on two occasions, yielding 5422 records. Following duplicate removal, the records were screened based on the following inclusion criterions; (1) in English or Nordic language and published between 2011-2022, (2) presenting results for self-harming and/or suicidal behavior on social media and (3) using tools for either interview or questionnaire aiming at assessment of the experience of online self-harming and suicidal behavior from the perspective of the person who engages in the behavior. A total of 64 articles were included.

45 used questionnaires, 17 used interviews, and two studies mixed the two approaches. 17% of the studies had made some effort to ensure validity within the questionnaires and 15.8% gave full access to the interview guide.

Research into online self-harming and suicidal behavior is characterized by a lack of validated measurements and methodological transparency. The results emphasize a need for further development, testing, and validation of questionnaires and greater openness and reflexivity in qualitative methodology to enable cross-study comparison and advance knowledge of this complex phenomenon.
