Brief summary: The goal of this acceptability and feasibility trial is to identify whether a six-session intervention for suspicious thoughts is feasible and acceptable to school-based adolescents.

The main research question is:

Is it feasible and acceptable to offer a brief imagery and values-based intervention for adolescents experiencing paranoia in schools?

Aims The primary aim of the current study is to identify whether a six-session brief intervention delivered in schools is feasible and acceptable to young people experiencing paranoia. Secondarily, it aims to identify preliminary outcomes of such an intervention on levels of paranoia, as measured by the Revised Green et al., Paranoid Thoughts Scale (R-GPTS).

Participants will be screened for paranoid thoughts and those eligible will be offered a six-session intervention. Participants will be asked to complete various measures prior to and following therapy.
