The problem of the present study lies in attempting to find answers to
the following questions:
1. Is there a correlation between the probability of suicide and
depression, pessimism, psychosis, neurosis, introversion, and
extroversion among the students of the University of Eden, Yemen,
who are addicted to khat?
2. Does the probability of suicide among the students of the University
of Eden, Yemen, who are addicted to khat vary with residence (rural,
urban), family socio-economic status (low, average, high), period of
khat addiction in years (1-2, 3-4 years or more), number of siblings (1-
4, 5-8 or more), and type of college (theoretical, practical)?
3. Do some psychological variables (depression, pessimism, psychosis,
neurosis, introversion, and extroversion) and some demographical
variables (residence, family socio-economic status, period of khat
addiction, number of siblings, and type of college) contribute to the
prediction of the probability of suicide among the students of the
University of Eden, Yemen, who are addicted to khat?
