Acceptability and Feasibility of a Brief Paranoia Intervention.

The goal of this feasibility and acceptability trial is to test whether a new brief talking therapy can be successfully provided to and is suitable for adolescents (16-18) who are seeking help from Child and Adolescent Mental Health Services (CAMHS). The main research question for the current study is: Is it feasible and acceptable to offer a brief values-based (helping young people identify what matters most to them) and imagery (using imagination to visualise positive experiences) intervention for adolescents experiencing paranoia in CAMHS? It also aims to identify preliminary clinical outcomes, particularly changes in paranoia severity as measured by the Revised Green et al., Paranoid Thoughts Scale (R-GPTS). Participants will complete an eligibility assessment and those eligible will be offered a six-session intervention. Assessment measures will be completed before, during and after the intervention.
