In samples of American and Kuwaiti college students, current and prior suicidal preoccupation were associated with measures of psychological disturbance, with depression being the strongest predictor of suicidality in both samples. Although the Kuwaiti students were more depressed than the American students, they reported less prior suicidal preoccupation.
A time-series study of suicide and homicide rates in Australia and New Zealand from 1950-85 provided limited support for Durkheim's theory of suicide and no support for Henry and Short's theory of the relationship between suicide and homicide. The need for rival theories is discussed.
A study in Canada of the accidental death rate from firearms, and of suicide and homicide rates by firearms and by all other methods, for the period 1975-85, indicated that the rates were positively associated with one another. The results were interpreted using a subcultural theory of violence, and the social policy implications of the results were discussed.

In 1985 in 18 nations measures of life satisfaction in college students were not associated with the suicide and homicide rates of 15- to 24-yr.-olds.
In 1980, long guns were used relatively more often for murder in states which were more rural and which had a greater proportion of hunters.
State suicide rates in 1980 varied gradually, rather than abruptly, with longitude, as did homicide rates with latitude.
Scores from two independent judges indicated that criteria derived from the clinical experience of a suicidologist were successful in differentiating genuine from simulated suicide notes.
The results of eight studies by Steven Stack on national suicide rates were replicated using a data set for 1980; however, a multivariate data analysis indicated that the many associations found by Stack reduced to one major correlate of national suicide rates--females' participation in the labor force.
30 suicidal deaths were examined for the presence of needs described by Henry Murray. The most common needs identified were harmavoidance and infavoidance. Other needs were present rarely and typically only in unusual suicides such as double suicides or seppuku.
In a sample of 70 nations in 1980, those nations with higher proportion of males relative to females were less developed.
A review of several listings of famous historical figures indicated that percentages of deaths due to suicide ranged from 0.3% to 13.3%, with a median of 2.9%.
