| Acceptability and feasibility measured by attendance rates of the sessions in the case series. A Microsoft Teams grid was created to note down attendance after each session, and safety in relation to experiences of adverse events. A record was kept on any reported experiences of any risk to self, to or from others, e.g., episodes of deliberate self-harm, hospitalizations, losses, relapses or any other traumatic experiences, measured through verbal feedback and qualitative feedback measured at the final session, the follow-up session, using a bespoke qualitative measure. | — |
