• Stress is thought to be one of the principal causes of psychological distress and physical illness.

Describe stressors

Stressors• A stressor is any adverse experience

(physiological, psychological or social) that causes a stress response.

• The stressor must be perceived as stressful by an individual to activate the stress response.

• There are individual variations as to what is perceived as stressful and research shows that humans can imagine stressors and experience the same physiological arousal as from external environmental stressors (Sapolsky, 1998)…..

• in other words just thinking about it can feel the same as it is actually happening.

Stressors

• Stressors are described as acute (i.e. sudden) or chronic (i.e. persisting over a longer period of time).

• Stressors may or may not cause stress in an individual depending on the person's capacity to cope with the stressors.

Examples are:• being diagnosed as

seriously ill, being involved in an accident or being injured

• life events such as the death of a loved one, divorce, being fired, or not getting admitted to a university.

Describe stressors

Chronic stressorsExamples are:• social stressors such as

poverty, illness, or being responsible for many young children

• unemployment, being bullied at work, or work place stressors

• violent relationships.

Describe stressors

Life events as stressorsHolmes and Rahe (1967)

• observed that major life changes often preceded illness.

• These events could be both positive and negative but they were perceived as stressful because the change required that the person should adapt to a new situation.

• Social Readjustment Rating Scale• The list of life events presented

by Holmes and Rahe may not apply to all or in that order…they recognize that some stresses are individualistic.
