(case theory) that gives the presented problem more clarity. Hypothesis substantiation through exploration of the problem: life history of the client, etiology, personality, environment, stigmas, etc. Further integration of newer facts identified in the treatment period and preparing a psychosocial report for psychosocial intervention. Assessment includes psychiatric, psychological and social functioning, risks posed to the individual and others, problems required to address from any co-morbidity, personal circumstances including family or other carers. Other factors are the person's housing, financial and occupational status, and physical needs. Assessments when categorized, it particularly includes Life history of the client that include data collection of living situation and finances, social history and supports, family history, coping skills, religious/cultural factors, trauma from systemic issues or abuse and medico-legal factors (assessment of the client’s awareness of legal documents, surrogate decision-making, power of attorney and consent). Components include: the resource assessment of psycho-spiritual strengths; substance abuse; coping mechanisms, styles and patterns (individual, family level, workplace, and use of social support systems); sleeping pattern; needs and impacts of the problem etc. Advanced clinicians incorporate individual scales, batteries and testing instruments in their assessments. In the late 1980s Hans Eysenck, in an issue of Psychological Inquiry, raised controversies on then assessment methods and it gave way to comprehensive Bio-Psycho-Social assessment. This theoretical model sees behavior as a function of biological factors, psychological issues and the social context. Qualified healthcare professionals conduct the physiological part of these assessments. This thrust on biology expands the field of approach for the client, with the client, through the interaction of these disciplines in a domain where mental illnesses are physical, just as physical conditions have mental components. Likewise, the emotional is both psychological and physical. The clinician’s comprehension and set of judgments about the client's situation, the assessment through a theory of each case, predicts the intervention. Hence a good psychosocial assessment leads to a good psychosocial intervention that aims to reduce complaints and improve functioning related to mental disorders and/or social problems (e.g., problems with personal relationships, work, or school) by addressing the different psychological and social factors influencing the individual. For example, a psychosocial intervention for an older adult client with a mental disorder might include psychotherapy and a referral to a psychiatrist while also addressing the caregiver's needs in an effort to reduce stress for the entire family system as a method of improving the client's quality of life.
