Social case work is a professional method of helping individuals solve personal, emotional, social, and environmental problems through a systematic helping process. To understand the client's situation effectively and provide suitable interventions, social case workers use a variety of tools. These tools help in collecting information, establishing a therapeutic relationship, assessing needs, planning interventions, and evaluating outcomes. The effective use of these tools depends on the worker's knowledge, skills, values, and ethical principles. Interview is the most important tool in social case work practice. It is a purposeful conversation between the social worker and the client aimed at understanding the client's problems, feelings, experiences, and expectations. Interviews may be structured, semi-structured, or unstructured depending on the nature of the case. Through interviews, the worker gathers relevant information, develops rapport, clarifies issues, motivates the client, and formulates an intervention plan. Observation is another essential tool used to understand the client's behaviour, emotions, communication style, family interactions, and living conditions. Observation may be direct or indirect, participant or non-participant. It helps the worker identify non-verbal expressions, inconsistencies between verbal and non-verbal communication, and environmental factors influencing the client's behaviour. Careful observation strengthens assessment and decision-making. Home
