Fluctuations in national levels of neuroticism and extraversion, 1935-1970.

National levels of neuroticism and extraversion in 18 advanced Western nations are measured at intervals from 1935 to 1970. It is shown that levels of neuroticism rose significantly in the nations that suffered military defeat and occupation in the Second World War and then declined during the 1950s to prewar levels. National levels of extraversion have been generally rising over this period.

Combined aortoiliac and femoropopliteal occlusive disease.

In a series of 140 patients operated upon for aortoiliac occlusive disease over 11 1/2 years, 81 had concomitant occlusion of the superficial femoral artery. These 81 patients with combined segment disease were studied with particular emphasis on the relief of presenting symptoms by an aortic bypass procedure alone. Fifty-three patients underwent only aortic bypass and could be fully evaluated postoperatively. Ninety-six per cent presenting with rest pain or ischemic changes obtained complete relief of these sympotms. All 53 patients presented with claudication, and 88.7 per cent either had complete relief or improved to the point that no further theapy was needed. The results of this study confirm the efficacy of restoration of proximal flow to the profunda femoris arteries as the primary therapeutic goal in patients with combined segment disease.

National differences in extraversion and neuroticism.

A method is proposed for measuring national differences in extraversion and neuroticism from demographic and epidemiological data. The method is to use national prevalence rates of a number of variables and treat them as indices of the levels of extraversion and neuroticism in national populations. The variables taken are the national rates of divorce, illegitimacy, accidents, crime, murder, suicide, alcoholism, chronic psychosis and coronary heart disease; and the per capita consumption of calories, cigarettes and caffeine. Data for these indices are presented for the advanced western nations. The relationship of these variables to extraversion and neuroticism among individuals is used to set up a model for their relationship among nations. The variables were factored by principal components analysis and this yielded two major factors identified as extraversion and neuroticism. The factor scores of each nation on the two factors were then computed. These indicate that the most extraverted nation is the United States and the most introverted is Japan. The most neurotic nation is Austria and the least neurotic is Ireland.
