Which theory describes human behavior in terms of complex systems and interdependence of parts within a social context?

• A. Psychodynamic theory
• B. Systems theory
• C. Rational choice theory
• D. Transpersonal theory

Answer: (B)

Systems theory treats human behavior as arising from interactions within a complex, interdependent set of parts embedded in a social context. People are not seen in isolation but as members of systems—families, teams, organizations, communities—where each part influences and is influenced by the others. Because these systems are dynamic, small changes in one component can ripple through the whole, and feedback loops help sustain or transform patterns over time. This holistic, multi-level perspective fits social work practice, where interventions often target relationships, environments, and structural factors, not just individual symptoms. In contrast, psychodynamic theory centers on internal drives and childhood conflicts, rational choice theory emphasizes individual cost-benefit decisions, and transpersonal theory focuses on spiritual or transcendent aspects.
