Suicidology: A Look Backward and Ahead

Using the metaphor of “a long run’ to describe our progress in suicidology, the author looks back to discuss important concepts that have become well established, such as clues to suicide, ambivalence, crisis services, suicide consultations, and psychological autopsies. An example is the psychological autopsy of Marilyn Monroe. Follow-up studies of crisis center clients have indicated that chronically suicidal clients are at the greatest risk of suicide. Recommendations for the long-term treatment of such patients are provided. Research on youth suicide is reported. Finally, the author looks ahead toward new developments in training and treatment.     

Drug Ingestions in Children 10–14 Years Old: An Old Problem Revisited

To determine changes in rates of drug ingestions in 10–14 year old children in our country, a retrospective chart review of 10–14 year olds hospitalized for drug ingestion between 1993–1995 and 2000–2004 was performed. Odds ratios and Chi‐square were used for analyses. From 1993–1995 there were 92.8 ingestions/100,000 children/year; from 2000–2004 there were 63.3 ingestions/100,000 children/year. More males ingested in 2000–2004 than 1993–1995 (26.3% vs. 14.2% O.R. 2.15 [1.19, 3.92]). More patients took psychiatric medications in 2000–2004 than 1993–1995 (38.9% vs. 27.0%, O.R. 1.72 [1.06, 2.80]). More patients ingested SSRIs in 2000–2004 than 1993–1995; fewer ingested tricyclics. Hospitalization rates for drug ingestions have decreased. There has been a change in drug ingested, and more males are ingesting drugs.     

Age and Gender Differences in the Use of Various Poisoning Methods for Deliberate Parasuicide Cases Admitted to Loghman Hospital in Tehran (2000–2004)

Different methods of poisoning used by individuals with the diagnosis of parasuicide admitted to the Loghman Hospital, Tehran, from 2000 to 2004 were investigated, with particular focus on gender and age differences. Drugs, pesticides, and other agricultural chemicals (women: 12.7%, men: 9%) were the most commonly used methods. In males, the percentage of use of drugs increased with age, but the frequency of pesticides use decreased with age. In females, drugs were most often used in the youngest age group, whereas the use of pesticides was lowest in the youngest age category. Females outnumbered males, especially in the youngest age group of 10 to 19 years olds. Drugs and pesticides were the substances used most often for parasuicide in each age group regardless of gender.     

The Benefit of Forgetting Suicidal Ideation

In a sample of young adult Australians, those who had had suicidal ideation but who did not acknowledge ever having had it when asked 4 years later, were experiencing better mental health, as demonstrated by significantly better functioning on a range of psychometric measures, than those who recalled it. These results are consistent with several recent reports and indicate that forgetting painful events such as suicidal ideation is an adaptive defense mechanism. This has implications in terms of therapy focusing on contemporaneous events and the future, rather than on the past.     

What Does Psychological Autopsy Study Tell Us About Charcoal Burning Suicide—A New and Contagious Method in Asia?

Charcoal burning suicides in Hong Kong between 2002–2004 in the 15 to 59‐year‐old age group were investigated using the psychological autopsy method. The psychopathological profiles of charcoal burning suicides (N = 53) were compared against “other suicides” (N = 97). The two groups did not differ significantly in the prevalence of DSM‐IV axis I diagnoses with the exception of schizophrenic spectrum disorder which was less frequently associated with charcoal burning suicides. Score on “neuroticism” in the NEO‐five Factor Inventory (NEO‐FFI) was significantly higher in victims of charcoal burning suicide. There was also a trend toward higher score on “conscientiousness” in the NEO‐FFI among charcoal burners than victims of other suicide.     

Interpersonal–Psychological Theory,Alexithymia, and Personality Predict Suicide Ideation among Maladjusted Soldiers in Taiwan

This case–control study enrolled 226 maladjusted soldiers and 229 controls to investigate the impact of the interpersonal–psychological theory of suicide, alexithymia, personality, and childhood trauma on suicide risk among Taiwanese soldiers. Assessments included the Toronto Alexithymia Scale, Eysenck Personality Inventory, Mini‐International Neuropsychiatric Interview, and Brief Symptom Rating Scale. In addition to thwarted belongingness and perceived burdensomeness, other risks included less extraversion with higher neuroticism, higher alexithymia, poor academic performance, domestic violence, and life‐threatening events. Our study demonstrates the interaction of the interpersonal–psychological theory and other suicide risk factors in Taiwanese soldiers.     

Trajectory of Adolescent Obesity: Exploring the Impact of Prenatal to Childhood Experiences

This study examined longitudinal associations of prenatal exposures as well as childhood familial experiences with obesity status from ages 10 to 18. Hierarchical generalized linear modeling was applied to examine 5,156 adolescents from the child sample of the 1979 National Longitudinal Survey of Youth. Higher maternal weight, maternal smoking during pregnancy, lower maternal education, and lack of infant breastfeeding were contributors to elevated adolescent obesity risk in early adolescence. However, maternal age, high birth weight of child, and maternal annual income exhibited long-lasting impact on obesity risk over time throughout adolescence. Additionally, childhood familial experiences were significantly related to risk of adolescent obesity. Appropriate use of family rules in the home and parental engagement in children’s daily activities lowered adolescent obesity risk, but excessive television viewing heightened adolescent obesity risk. Implementation of consistent family rules and parental engagement may benefit adolescents at risk for obesity.
