Clinical assessment involves evaluating an individual's strengths and weaknesses, conceptualizing the problem, and prescribing treatment. The assessment process begins with a referral question from the referral source. The clinician must understand the precise referral question being asked. The assessment interview is a basic and useful technique where the clinician can exercise skill and adaptability to make clinical decisions. Establishing rapport through a comfortable atmosphere and mutual understanding of the interview purpose allows the clinician to achieve the interview goals. Different types of interviews like intake, case history, mental status, crisis, and diagnostic interviews each have specific purposes in the assessment process.
