Group work is a form of voluntary association of members benefiting from cooperative learning, that enhances the total output of the activity than when done individually. It aims to cater for individual differences, develop skills (e.g. communication skills, collaborative skills, critical thinking skills), generic knowledge and socially acceptable attitudes or to generate conforming standards of behavior and judgement, a 'group mind'.Social group work is a method of social work that helps persons to enhance their social functioning through purposeful group experiences and to cope more effectively with their personal, group or community problems (Marjorie Murphy, 1959).“The group worker enables various types of groups to function in such a way that both group interaction and programme activities contribute to the growth of the individual, and the achievement of the desirable social goal. The objectives of the group worker include provision for personal growth according to individual capacity and need; the adjustment of the individual to other persons, to groups and to society, the motivation of the individual toward the improvement of society and; the recognition by the individual of his own rights, abilities and differences of others. Through his participation the group worker aims to effect the group process so that decisions come about as a result of knowledge and a sharing and integration of ideas, experiences and knowledge, rather than as a result of domination from within or without the group. Social Work Intervention with Individuals and Groups through experience he/she aims to produce those relationship with other groups and the wider community which contributes to responsible citizenship, mutual understanding between cultural, religious, economic or special groupings in the community, and a participation in the constant improvement of our society towards democratic goals. The guiding purpose behind such leadership rests upon the common assumptions of a democratic society; namely, the opportunity for each individual to fulfill his capacities in freedom, to respect and appreciate others and to assume his social responsibility in maintaining and constantly improving our democratic societies. Underlying the practice of group work is the knowledge of individual and group behaviour and of social conditions and community relations which is based on the modern social sciences. On the basis of this knowledge the group worker contributes to the group with which he works with a skill in leadership which enables the members to use their capacities to the full and to create socially constructive group activities. He is aware of both programme activities and of the interplay of personalities, within the group and between the group and its surrounding community. According to the interests and needs of each, he assists them to get from the group experience, the satisfaction provided by the programme activities, the enjoyment and personal growth available through the social relations, and the opportunity to participate as a responsible citizen. The group worker makes conscious use of his relations to the group, his knowledge of programme as a tool and his understanding of the individual and of the group process and recognizes his responsibility both to individuals and groups with whom he works and the larger social values he represents”.Group work in psychology is done with a smaller number of participants for controlled effectiveness. It is an ethical practice that aims to bring out a collective positive behavioral and well-being change in the individual participants life.
