In the field of social work, a person would employ various psychological theories and approaches to better understand and assist individuals in need. One such approach is cognitive-behavioural therapy, which focuses on identifying and modifying negative thought patterns and behaviours. Additionally, person-centred therapy emphasizes empathy, unconditional positive regard, and active listening to foster a therapeutic alliance. Furthermore, psychodynamic theory delves into unconscious processes and childhood experiences to uncover underlying issues. By integrating these psychological perspectives into their practice, social workers can effectively address the diverse needs of their clients.
