This document discusses various concepts related to maladaptive behavior, stress, crisis, and disaster from a psychological perspective. It begins by explaining homeostasis and how adaptation occurs in response to threats to homeostasis. Group adaptation requires good communication, respect, resources, and experience with stressors. Stress is defined as any change causing disturbance that an organism must adapt to in order to survive. A crisis is a stressful threat that exceeds one's coping abilities, while a disaster greatly exceeds the coping capacity of an affected community. The document goes on to discuss various biopsychosocial factors influencing mental illness and different types of psychopathology involving personality, behavior, perception, thought, affect, attention, consciousness, and memory.

1. MALADAPTIVE
BEHAVIOR OF
INDIVIDUALS AND
GROUPS: STRESS,
CRISIS AND DISASTER

2. All living organisms have a tendency to
maintain themselves in a state of relative
constancy called as Homeostasis.
Adaptation occurs when there is a threat to
this homeostasis. Adaptive responses occurs
when a stimulus from the internal or external
environment causes a departure from the
balanced state of organism.

3.  Group adaptation is a process by which the
group maintains a balance so that it can
promote growth of individual and group
members.
For group to adapt successfully there must be:
1) Good communication skills.
2) Mutual respect for each other
3) Adequate resources available for adaptation
4) Previous experience with stressors

4. The word “Stress” was derived from Latin word
“Stringere” which means “to draw tight”.
Change in the internal/ external environment
causes stress and an organism has to adapt to
it to survive. The stimulus preceding or
precipitating the changes are called stressors.

5.  Crisis is a disturbance caused by a stressful
event or a perceived threat. The person usual
way of coping becomes ineffective in dealing
with the threat, causing anxiety.
 Disaster is defined by the WHO as “A severe
disruption, ecological and psychological, which
greatly exceeds the coping capacity of the
affected community. It can be natural and man
made, psychological reaction may be either
adaptive or maladaptive.

6. ETIOLOGY: BIO-
PSYCHO-SOCIAL
FACTORS

7.  Previously, cause of mental illness was
explained through humoral, demonic and
physical theories. However, over the last few
decades, a number of theories have been
elaborated to explain psychiatric disorders on
a scientific basis:
Some of these are:
1. Genetic theories
2. Biochemical theories
3. Psychological theories
4. Behavioral and cognitive theories

8. Cause of mental illness can be chronologically
divided into 3 groups:
I. Pre- disposing Factors:
These occurs before the onset of the disease
or before psychopathology have appeared.
1) Genetic Factors
2) Biological Factors
3) Psychological Factors

9. II. Precipitating Factors:
These are events that occur shortly before
the onset of disorders and appear to have
induced it.
1) Physical Factors
2) Physiological Factors
3) Psychological Factors
4) Social factors

10. III. Perpetuating Factors:
These are factors that prolong the course of a
disorder after it has been provoked. It is
extremely vital to consider these factors while
planning treatment.

11. PSYCHOPATHOLOGY
OF MENTAL
DISORDERS

12. Meaning of Psychopathology:
Psychopathology is the systematic study of
abnormal experience, cognition and behavior.
It involves the observation and categorization
of abnormal psychic events, internal
experiences of the patient and his consequent
behavior.
Disorder may be due to disorder of personality,
activity, perception, thinking, affect, attention,
consciousness, memory and structural
disturbances in the brain
