A mental state examination (MSE) is done on patients to identify their ability to conceptualise problems, process information, make decisions, and sound judgement was done (Royal collage of psychiatry, 2013). Simms (2015) argues that MSE is a structured clinical way of observing and describing a patient’s state of mind considering their behaviour, mood, thought process, speech, cognition, emotional state and affects. Global Assessment of Functioning (GAF) tool was used to examine Mark’s mental state and assess his general functioning. The A clinician-rated 0-100 scale was used to assess psychological distress and disturbance, social and occupational functioning (First and Pincus 2012). The GAF tool was also used to assess his psychosocial and holistic needs by the Psychologist to explore psychological and social factors related to his experience. This was done by gathering information about his family and key individuals involved in his life. Other factors considered included the relationships that were important to him, social inclusion and functioning, spirituality, work and vocational strength (Greenhalgh, 2010). Though GAF was a good tool to assess his mental state and general functioning, The Health of the Nation Outcome Scale (HoNOS) tool would have been better to use because it does not only examine mental state and general functioning but also examines both clinical problems and social functioning as well as providing a broad-based approach of another aspect of health to be assessed and examine. According to Ibrahim et al., (2014), such aspects include carers burden, quality of life, patient’s satisfaction, needs assessment.
