[The Integrated Model of Work Stress (ISR) model] is straightforward, easy to understand, and has guided much of the work stress research and theorizing in the past 25 years.

Organizational constraints represent situations or things that prevent employees from translating ability and effort into high levels of job performance. The [Organizational Constraints Scale] OCS was based on the work of Peters and O'Connor (1980), who listed 11 areas of constraints that interfered with job performance. These common situational constraints in organizations may include faulty equipment, incomplete or poor information, or perhaps interruptions by others.

Organizations are complex social systems that sometimes perform remarkably well and sometimes fail miserably. Organizational psychology is a subfield within the larger domain of industrial/organizational psychology that seeks to facilitate a greater understanding of social processes in organizations. Organizational psychologists also seek to use these insights to enhance the effectiveness of organizations—a goal that is potentially beneficial to all.

Job performance is a deceptively simple term. At the most general level, it can be defined simply as “all of the behaviors employees engage in while at work.” Unfortunately, this is a rather imprecise definition because employees often engage in behaviors at work that have little or nothing to do with job-specific tasks.

By definition, job performance is behavior, so job performance is rarely measured directly. More typically, what is measured is some external assessment of job performance.

Job satisfaction is, without a doubt, one of the most heavily studied topics in organizational psychology, as well as in the broader field of industrial/organizational psychology. To emphasize this point, many authors, over the years, have referred to Locke’s chapter in the Handbook of Industrial and Organizational Psychology (1976), where he reported that studies dealing with job satisfaction numbered in the thousands.

The earliest scientific investigations related to the field of occupational stress were conducted by the well-known physiologist in the early part of the twentieth century (e.g., Cannon, 1914). Cannon was a pioneer in the investigation of the relationship between emotions and physiological responses, and is perhaps best known for having coined the term homeostasis.
