Final answer:
The correct answer is 'Organizational psychology,' a branch of psychology that emphasizes improving organizational effectiveness and employee well-being by focusing on social interactions, job satisfaction, and organizational culture.
Step-by-step explanation:
Organizational psychology is the correct answer to the question of which collection of social psychology methods is employed to improve organizational effectiveness and employee well-being. This branch of psychology focuses on social interactions and their effects on individuals and organizations as a whole. Organizational psychology involves understanding job satisfaction, leadership, management styles, and organizational culture.
Within the field of Industrial and Organizational (I-O) psychology, industrial psychology looks at aspects like hiring and employee training, while organizational psychology is more concerned with employee relationships and the overarching culture of the organization. Job satisfaction, which is a measure of the degree of pleasure that employees derive from their jobs, falls squarely under the realm of organizational psychology.
Given these considerations, the best way to refer to the practices that enhance both the efficiency of an organization and the welfare of employees is to talk about organizational development from an organizational psychology perspective. This includes fostering a positive workplace culture to ensure that employees are not only efficient but satisfied and well-adjusted in their roles.
