Because human behavior is complex and the social work profession is broad, numerous theories are utilized for
social work practice at the micro-meso-macro levels. These theories focus on human growth and development,
psychological and social functioning, and social service delivery. Some theories emphasize social and economic
justice. All theories are value-laden and come out of a socio-historical context. Thus, all theories should be critiqued
with attention paid to their cross-cultural applicability.
