Dataset for validation of the self-Dehumanisation in Psychosis Scale (DiPS): measuring feelings of self-dehumanisation in people who experience psychosis

The dataset contains data collected from 456 people with experience of psychosis who participated in a study to validate the self-Dehumanisation in Psychosis Scale (DiPS). Demographic information includes ethnicity, gender, age, diagnosis, and whether a person is taking anti-psychotic medication. There are data from five self-report questionnaires collected at one time point: self-Dehumanisation in Psychosis Scale (DiPS); Self Compassion Scale Short Form (SCS-SF) (Raes et al., 2013), Revised Green et al., Paranoid Thoughts Scale (R-GPTS) (Freeman et al., 2021); Hamilton Programme for Schizophrenia Voices Questionnaires (HPSVQ), (Van Lieshout & Goldberg, 2007); Internalized Stigma of Mental Illness Inventory-9 (ISMI-9) (Hammer & Toland, 2017).
The DiPS was completed at a second time point 3-7 days after the first to assess test-retest reliability. A subset of 197 participants completed the DiPS at the second time point.
