Sources of Stress

The circumstances that cause stress are called stressors. Stressors vary in severity and duration. For example, the responsibility of caring for a sick parent may be an ongoing source of major stress, whereas getting stuck in a traffic jam may cause mild, short-term stress. Some events, such as the death of a loved one, are stressful for everyone. But in other situations, individuals may respond differently to the same event—what is a stressor for one person may not be stressful for another. For example, a student who is unprepared for a chemistry test and anticipates a bad grade may feel stress, whereas a classmate who studies in advance may feel confident of a good grade. For an event or situation to be a stressor for a particular individual, the person must appraise the situation as threatening and lack the coping resources to deal with it effectively.

Stressors can be classified into three general categories: catastrophic events, major life changes, and daily hassles. In addition, simply thinking about unpleasant past events or anticipating unpleasant future events can cause stress for many people.

A.

Catastrophes

A catastrophe is a sudden, often life-threatening calamity or disaster that pushes people to the outer limits of their coping capability. Catastrophes include natural disasters—such as earthquakes, tornadoes, fires, floods, and hurricanes—as well as wars, torture, automobile accidents, violent physical attacks, and sexual assaults. Catastrophes often continue to affect their victims’ mental health long after the event has ended. For example, in 1972 a dam burst and flooded the West Virginia mining town of Buffalo Creek, destroying the town. Two years after the disaster, most of the adult survivors continued to show emotional disturbances. Similarly, most of the survivors of concentration camps in World War II (1939-1945) continued to experience nightmares and other symptoms of severe emotional problems long after their release from the camps.

B.

Major Life Changes

The most stressful events for adults involve major life changes, such as death of a spouse or family member, divorce, imprisonment, losing one’s job, and major personal disability or illness. For adolescents, the most stressful events are the death of a parent or a close family member, divorce of their parents, imprisonment of their mother or father, and major personal disability or illness. Sometimes, apparently positive events can have stressful components. For example, a woman who gets a job promotion may receive a higher salary and greater prestige, but she may also feel stress from supervising coworkers who were once peers. Getting married is usually considered a positive experience, but planning the wedding, deciding whom to invite, and dealing with family members may cause couples to feel stressed.

C.

Daily Hassles

Much of the stress in our lives results from having to deal with daily hassles pertaining to our jobs, personal relationships, and everyday living circumstances. Many people experience the same hassles every day. Examples of daily hassles include living in a noisy neighborhood, commuting to work in heavy traffic, disliking one’s fellow workers, worrying about owing money, waiting in a long line, and misplacing or losing things. When taken individually, these hassles may feel like only minor irritants, but cumulatively, over time, they can cause significant stress. The amount of exposure people have to daily hassles is strongly related to their daily mood. Generally, the greater their exposure is to hassles, the worse is their mood. Studies have found that one’s exposure to daily hassles is actually more predictive of illness than is exposure to major life events.
