acquiring life gaols. Promoting recovery induce people to overcome from such obstacles and
help them to achieve desirable goals. However, some of the CBT approaches are available
which is adapted by UK government in order to reduce effects of depression and anxiety. Based
on evidenced based methods the study has developed a new intervention which is designed
which help individuals to achieve personal goals and enhance recovery that can be deliver by
mental care practitioners of Frontline. A small scale pre-piolet study has been conducted in order
to evaluate the effectiveness of intervention where six staff member deliver the intervention to 12
service users. All the participants showed clinical improvement and were able to acquire their
goals. There was a positive feedback of both staff members and service users for the
intervention. Aim of this study is to run a controlled trial for the intervention which is particular
designed for individuals with psychosis. GOALS study which is Getting On top

for emotional problems for psychosis. The study has adapted CBT to address particular needs
and problems of individuals with psychosis. The advantage of GOALS approach is that it is brief
