Diagnosis is the second major process in social casework practice, where the social worker attempts to understand the client's social situation and personality based on information collected. The social worker forms an opinion about the nature of the client's problem and the type of help needed. Diagnosis has three components: the client's problem and goals, the client's social and psychological situation, and the agency's ability to provide help. There are three types of diagnosis: dynamic diagnosis focuses on current issues; clinical diagnosis classifies the client's problem; and etiological diagnosis explains the origins of the client's problem.
