This study focuses on task-centered intervention strategies in order to attain a variety of goals that regularly arise in short-term clinical work with both individuals and families. These strategies involve problem-solving actions or tasks carried out by clients in the treatment session, at home or in the community. A task consists of acting in a planned way to solve a problem, rather than talking about the problem as a means to develop insight or promote personal growth. The author emphasizes a collaborative effort in which practitioners help clients to design, plan, practice and implement tasks and learn to resolve difficulties through their own problem-solving actions.
