The systematic study of dispositional and situational variables that influence the behaviors and experiences of individuals and groups at work is organizational psychology. Which area of industrial-organizational (I-O) psychology measures job satisfaction? The answer to this question is organizational psychology (B). Organizational psychology focuses on the social dimensions of work, which includes examining aspects such as job satisfaction, the effects of management and leadership styles on productivity, and the impact of organizational culture on employee outcomes. This branch of psychology conducts in-depth research to understand the various determinants of job satisfaction and the potential consequences that these satisfaction levels can have on both individuals and the organization as a whole.
Job satisfaction is a key area of study within organizational psychology because it can significantly influence workplace harmony and productivity. Factors that contribute to job satisfaction include the nature of the work, compensation, growth opportunities, workplace environment, and interpersonal relationships within the organization. Therefore, organizational psychologists strive to optimize these factors to enhance overall employee satisfaction and, in turn, drive organizational success.
