Love and achievement motives in women's and men's suicide notes.

It is often assumed that women kill themselves because of love and men because of achievement problems. The authors evaluated the suicide notes of 56 U.S. adult women and men with regard to love and achievement motives. Love themes were significantly more common than achievement themes, independent of sex and age. This suggests that, at least for U.S. adults who leave suicide notes, relationship concerns may be a dominant component of the motivation for suicide.

Can personality predict suicidality? A study in two cultures.

Kuwaiti (n = 460) and American (n = 273) undergraduates responded to seven questionnaires in Arabic and English, respectively. It was found that Kuwaiti students attained significantly higher total mean scores on ego-grasping orientation (anti-Taoist orientation), death obsession, pessimism, obsession-compulsion and anxiety scales than the American students, while the latter group had a significantly high mean score on an optimism scale. There were no significant differences between the groups in suicidal ideation. Almost all the Pearson inter-correlations between these scales were significant and positive, except that those between the scale scores and optimism scores were negative. The unrotated factor was bipolar, clear and high-loaded, labeled "Negative affect versus optimism". Multiple regression revealed that the best predictors of suicidal ideation were pessimism, death obsession and anxiety in the Kuwaiti students, while they were optimism (negatively), anxiety, pessimism, death obsession and male sex in the American students, respectively. The other scales did not contribute significantly to the prediction of suicidal ideation.

Serum cholesterol levels and suicide: a meta-analysis.

A meta-analysis was performed on studies exploring the link between low levels of serum cholesterol and increased risk of suicide. Follow-up studies found that those with lower cholesterol levels do have a tiny but statistically significant increased risk of completing suicide. Individuals who have attempted suicide in the past have lower cholesterol levels, especially if they used violent methods for suicide. Cholesterol lowering studies, however, did not lead to a significant increase in completed suicide.

PC anxiety: reliability and validity of a brief scale.

A brief six-item scale to measure confidence in the use of personal computers showed Cronbach alpha of .76 for internal reliability and construct validity (r(pb)s of -.16, -.18, -.22 for items of behavioral use).

Regional variation of divorce in Germany.

The correlates of provincial divorce rates in Germany in 1996 were marriage rates, birth rates, population density, and formerly East versus West Germany.

Blood type and bipolar disorder.

Type I bipolar patients in Budapest were reported to have type O blood more often and types A and B blood less often than Type II bipolar patients.

Murder rates in the regions of Germany.

Murder rates in the 16 German Bundeslander were associated with marriage, infant mortality, unemployment, and suicide rates and with population density.

Furnham's Money Attitude Scale.

An item-analysis of responses from 186 undergraduates to the Money Attitude Scale developed by Furnham did not replicate the factor pattern which he derived.

Manic-depressiveness, obsessive-compulsive tendencies, and suicidality in Kuwaiti college students.

In a sample of 87 Kuwaiti undergraduates (20 men, 67 women), obsessive-compulsive scores were associated with scores on measures of mania, depression, and suicidal thoughts. Multiple stepwise regression indicated that (a) obsession, suicidal attempts, and suicidal threats were predictors of depression, (b) depression, suicidal attempts, and obsession predicted suicidal thoughts, (c) age, doubting, and sex were predictors of suicidal threats, and (d) suicidal thoughts, depression, and obsession were predictors of suicidal attempts.

Factorial validity of the Arabic Obsessive-Compulsive Scale in two cultures.

The Arabic Obsessive-Compulsive Scale and the Maudsley Obsessional Compulsive Inventory were administered to 87 Kuwaiti (Arabic version) and 73 American college students (English form). Pearson correlations for the total score on the Arabic scale and the four subscores of the Maudsley scale: Checking, Cleaning, Slowness, and Doubting were .72, .48, .50, and .61 for the Kuwaitis and .52, .40, .51, and .52 for the Americans. The loadings of the total score of the Arabic scale onto a factor of obsession and compulsion were .83 and .79 for Kuwaiti and American students, respectively, denoting a good factorial validity of the Arabic scale.

Trends in mass murder.

From 1976 to 1996, the proportion of murder incidents with 5 or more victims showed no linear trend or association with selected social indicators, e.g., birth rate, unemployment rate, and homicide rate.

Homicide↗

Finno-Ugrians and homicide.

The percentage of Finno-Ugrians in the population in 30 European nations in 1990 was not associated with the national homicide rates.

Using the short subscales of a questionnaire to assess subcomponents with low reliabilities: a cautionary note.

Some authors of personality questionnaires use factor analysis with the aim of constructing subcomponents to assess subsidiary traits within the broad domain tapped by the scale. However, these short subscales suffer from low reliabilities in most cases. The findings of using the Maudsley Obsessional-Compulsive Inventory in American (n=73) and Kuwaiti (n=87) college students justified the caution against using such short subscales with low reliabilities, inasmuch as 7 out of the 8 alpha reliabilities were less than .69, ranged from .35 to .68, and the median was .56.
