The possible reasons for the changes observed in the survey of 2002 are:
- Killing oneself.
- Drug abuse.
- Psychosis.
What is a survey?
This is research where a list of questions is aimed at extracting specific data from a particular group of people.
These changes were observed in the risk behaviour of the youths as there was a high case of premature deaths as many of these deaths were traced to cases of killing oneself.
There was an increase in health conditions and rapid behavioural changes as the youth got involved in substance and drug abuse.
The trauma and abuse resulting from these landed many others who neither had health issues nor death cases relapsed into psychosis which is an abnormal condition of the mind which results in having difficult times knowing what is real or not.
Therefore, the changes observed in the survey of 2002 are psychosis, killing oneself and drug abuse.
