A social worker must have a variety of knowledge and understanding of theories when working with individuals. I will begin this essay by examining what theory is and the nature of the relationship between theory and practice. I will discuss two specific theories, namely Cognitive Behavioral Therapist (CBT) and Person-Centered Approach. While explaining the theories, I will identify their underlying values ​​and explain how they might support, or even conflict with, social work values. C. Becket DATE explains how social work practice is extremely diverse in many ways. There are a number of service user groups that social workers work with. Some of these include children and families, young offenders, seniors, adults and children with mental health issues.

Hall and Scragg (2012) start from a person-centred approach...... middle of paper ...... services for older people and need to think carefully about planning to meet their needs. It is important that the needs of older people are met and that emphasis is placed on them throughout the intervention. It is important to inform them fully. The National Framework of Standards for Older People sets standards to ensure that services effectively meet the needs of individuals in social work practice. This is done through appropriate planning, assessment, intervention, monitoring and review. Historically, the assessment process has not been truly clear in social work, which can lead to a lack of precision. Therefore, social work focuses more on explaining intervention methods rather than assessment models.
