What stress is and what it isn’t
•Stress is one’s reaction to any change that requires a restructuring of one’s orientation to any given situation.
•It is not always a detrimental reaction.

Stressor
•Any stimulus that causes tension.
•May contribute to certain illnesses.

•Distinguished between adaptive and maladaptive responses:
•Adaptive—responses that preserve one’s physical and/or mental integrity
•Maladaptive—responses that interrupt the individual’s physical and/or mental integrity.

Methods of Conceptualizing Stress•As a biological response (Selye)
•As an environmental event
•As a transaction (Lazarus and Folkman)

Hans Selye (1976)
•Described the “General Adaptation Syndrome.”
•The physical reaction to stress prompting the “fight or flight” syndrome.
•The reaction occurs in 3 defined stages.

1. Alarm Reaction Phase
•“Fight or flight” responses are stimulated.•Sympathetic nerves release acetylcholine•Adrenal medulla releases epinephrine and
norepinephrine.•Trigger immediate increase in heart rate
and breathing, blood vessels constrict and muscles tighten.
•Initiates spontaneous behaviors associated with combat or escape.

2. Stage of Resistance
•The triggered physiological responses of Stage 1 are used to defend the individual in an attempt to adjust to the stressor (adaptation).
•If adaptation is successful, this is the end of the biological response and Stage 3 does not occur.
•Eventually the physiological responses decline.

3. Stage of Exhaustion
•Occurs if adaptation is not successful.•The person/body fatigues under the
internal stress of the physiological responses of the sympathetic nervous system.
•Reserves are depleted.•Stage is associated with disease and even
death.

Multiple Definitions of Mental Health
•Successful adaptation to stressors…•from internal and external
environments…•with thoughts feelings and behaviors that
are…•age appropriate and •congruent with local and cultural norms

Cultural Relativity
•Culture and society determine normal and abnormal behavior.
•The more removed a culture is from the mainstream culture of a society, the more likely any aberrant behavior will be met negatively.

Maslow’s Hierarchy of Needs
•A “humanistic” psychologist•Theory focuses on potentials of the
individual•Humans are constantly striving for higher
levels of capabilities•Always seeking higher levels of
consciousness, creativity and wisdom•The obstacles of society prevent reaching
the next higher level
