Preventive measures of mental illness
Prevention of mental illness:
The prevention of mental illness is based on public health principles and has been divided into:
1. Primary prevention.
2. Secondary prevention.
3. Tertiary prevention.
The aim of prevention is to decrease, the onset (incidence), duration (prevalence) and residual disability of mental disorder.
A. Primary Prevention:
Primary prevention involves the promotion of general mental health and protection against the occurrence of specific diseases. Primary prevention aims to prevent the onset of a disease or disorder, thereby reducing the incidence (number of new cases occurring in a specific period of time).
Measures for primary prevention include:
1. Elimination of etiological agents.
2. Reducing risk factors.
3. Enhancing host resistance or interfering with disease transmission.
4. Reducing stress factors
5. Counseling
➤ Student’s counseling
➤ Marriage counseling
➤ Sex counseling
➤ Genetic counseling.
6. Special centers
➤ Child guidance center
➤ Crisis intervention center
➤ Geriatric center
7. Mental health education
➤ The message of prevention, early recognition and effective treatment should reach them.
➤ Repeated efforts to give correct information will lead to a positive change and the misconceptions about mental illnesses removed.
B. Secondary Prevention:
Early identification and effective treatment of an illness or disorder with the goal of reducing the prevalence (total number of existing cases in a year) is the aim of secondary prevention.
The essential components of secondary prevention are
➤ Population screening
➤ Crisis intervention services
➤ Mental health promotion
C. Tertiary prevention:
This aims to reduce the prevalence of residual defect or disability due to illness or disorder. Tertiary prevention involves rehabilitation after defect and disability have been fixed. Human behavior can be changed, by gradual shaping, into completely new responses.
This can be achieved by behavior therapy methods like token economy. Modem tertiary prevention of mental illness or rehabilitation of the seriously disabled mentally ill persons is one of the great success stories of psychiatry.
