Developmental Trends in Adolescent Suicidal Ideation

Research using retrospective or cross‐sectional data suggests that suicidal ideation rates peak during mid‐adolescence. This study used a longitudinal, community sample of adolescents who reported suicidal ideation repeatedly over 7 years to examine suicidal ideation trends. We hypothesized that a mid‐adolescence peak in ideation is limited to adolescents exposed to friends' or family members' suicidality. Ideation trends were compared across groups exposed and not exposed to others' suicidality and statistically assessed using growth curve analyses. Overall, ideation rates peaked at age 15 years. Group comparisons revealed that the peak was limited to adolescents whose parents reported suicidality.

Depression and Suicidal Ideation Among Mexican American School-Aged Children

The purpose of this study was to describe depression and suicidal ideation rates in a community sample of 182 urban fourth and fifth grade Mexican American children using the Children's Depression Inventory (CDI). We used a descriptive secondary data analysis design. The mean CDI score was 9.55 (SD = 5.8). Thirty-one percent fell in the depressed range using a clinical cut point of 12 and 7% fell into the depressed range using the non-clinical cut point of 19. Thirty-eight percent (n = 69) reported suicidal ideation. The depression rate was consistent with national rates. A non-clinical cut point of 19 showed that 87% of children reporting suicidal ideation were not identified as depressed. Many of these children do not report the most typical symptoms of depression. The results of this study provide school nurses with vital information to support efforts addressing the mental health needs of Mexican American children.

Discrimination and delusional ideation.

In the UK and The Netherlands, people with high rates of psychosis are chronically exposed to discrimination. To test whether perceived discrimination is associated longitudinally with onset of psychosis. A 3-year prospective study of cohorts with no history of psychosis and differential rates of reported discrimination on the basis of age, gender, disability, appearance, skin colour or ethnicity and sexual orientation was conducted in the Dutch general population (n=4076). The main outcome was onset of psychotic symptoms (delusions and hallucinations). The rate of delusional ideation was 0.5% (n=19) in those who did not report discrimination, 0.9% (n=4) in those who reported discrimination in one domain, and 2.7% (n=3) in those who reported discrimination in more than one domain (exact P=0.027). This association remained after adjustment for possible confounders. No association was found between baseline discrimination and onset of hallucinatory experiences. Perceived discrimination may induce delusional ideation and thus contribute to the high observed rates of psychotic disorder in exposed minority populations.

Suicidal ideation and acts of self-harm among Dublin school children

The purpose of this study is to ascertain rates of suicidal ideation and self-harm in a classroom population of 13- and 14-year-old children using a screening questionnaire and to confirm accuracy of these screening results by home interview.There were significant differences between suicidal ideation rates at screening and at home interview (44%vs. 29%) and between self-harm rates (8%vs. 2%). Those with suicidal ideation at home interview believed more in a "right to suicide" and believed suicidal ideation to be more widespread among adolescents. School factors were believed by respondents to be important in the causation of adolescent suicide. Fewer than one-fifth would advise consultation with a psychiatrist to a suicidal friend.

Panic-associated suicidal and aggressive ideation and behavior

Some investigators have noted an increased incidence of suicidal ideation and attempts in individuals with panic attacks. The direct temporal relationship between the panic state and suicidal thoughts and behaviors has not been well elucidated however. Furthermore, although aggressive behavior is often manifested in individuals with suicidal behavior, the relationship between aggression and panic has received little attention. The aim of this study was to assess the frequency and type of reported suicidal and aggressive ideation and behaviors that occur during the panic state in patients with panic disorder. In order to evaluate the contribution of depression, individuals with pure (i.e. uncomplicated) panic disorder were compared with individuals who had comorbid panic and major depression. Nineteen patients with a diagnosis of pure panic disorder and 28 patients with comorbid panic plus major depression were included in the study. All patients were given the Panic, Suicide and Aggression Scale (PSAS), a questionnaire specifically designed to assess reported suicidal and aggressive thoughts and behaviors that occur during panic attacks. Other scales given to all patients included overall measures of impulsivity, suicide risk and violence risk. Patients with pure panic disorder reported high rates of suicidal and aggressive ideation and behavior during panic. The presence of comorbid depression resulted in a doubling of the rate of reported panic-associated suicidal ideation, property destruction and assaults, and a five-fold increase in the rate of homicidal ideation. The rate of reported suicide attempts was equal in the pure panic and comorbid group. There were also high correlations in all panic patients between measures of panic-associated suicide and aggression with the psychometric measures of impulsivity, suicide risk and violence risk.

Suicidality among adolescent Alberta Indians.

A high rate of suicide attempts and suicide ideation characterized a sample of 229 grade 7 to 9 adolescents resident on seven reserves in central Alberta. The prevalence of suicidality for these adolescent Indians was very similar to rates reported for Navajo youth and for 8th- and 10th-grade American non-Indian students. Comparison of Indian and non-Indian suicidality risk factors showed somewhat elevated levels of family disruption and psychological problems among Indian adolescents. Compared to Canadian nonadolescents, substance abuse levels were high, and conditions necessary to modeling were virtually omnipresent. Suicide ideation was significantly elevated for Indian adolescents with low psychological well-being, no father in the home, and a prior suicide in the household. Controlling for age, risk factors for suicide attempts were heavy alcohol use, no father in the home, sleeping problems, and low psychological well-being. The high rates of adolescent Native suicide imply that a much higher proportion of their suicide attempts succeed. Targeted, community-based counselling and educational programs are needed to address these problems.

Evaluation of Suicidality During Pharmacologic Treatment of Mood and Nonmood Disorders

Double-blind, controlled clinical trial data were evaluated to assess a hypothetical relationship between fluoxetine and suicidality (suicidal acts and ideation) in patients with mood (n = 5,655) and nonmood disorders (n = 4,959) (Mantel-Haenszel incidence difference method). In mood disorders, act rates (suicide attempts/completions) were low (treatment differences nonsignificant). Substantial suicidal ideation emerged less frequently with fluoxetine than placebo and was comparable with fluoxetine and tricyclic antidepressants. Improvement in ideation was greater with fluoxetine than placebo; it was comparable with fluoxetine and tricyclic antidepressants (United States trials) and greater with tricyclic antidepressants than fluoxetine (international trials). In nonmood disorders, no suicides occurred. Act and emergent ideation rates were low (treatment differences nonsignificant). Results do not suggest a causal relationship between pharmacotherapy and emergence of suicidality. Fluoxetine or tricyclic antidepressants reduce suicidal ideation and may protect against the emergence of substantial suicidal ideation.

Suicidal Behaviors and Childhood-Onset Depressive Disorders: A Longitudinal Investigation

In this longitudinal study, the rates and correlates of suicidal ideation and suicide attempts were determined among outpatient youths with depressive disorders and youths with other psychiatric disorders. At study entry, about 66% of the subjects evidenced suicidal ideation and 9% already attempted suicide. The rate of ideation remained fairly stable over time, whereas the rate of attempts reached 24% by the average age of 17 years. Major depressive and dysthymic disorders were associated with significantly higher rates of suicidal behaviors than were adjustment disorder with depressed mood and nondepressive disorders. In the presence of affective disorders, comorbid conduct and/or substance use disorders further increased the risk of suicide attempts.

Suicide ideation and attempts in Hispanics and non-Hispanic whites: demographic and psychiatric disorder issues.

This study examined the lifetime prevalence of suicide ideation and attempts in a community sample of 1,425 Hispanics and 1,309 non-Hispanic whites. The relationship between psychiatric disorder (as assessed by the Diagnostic Interview Schedule, or DIS) and suicide ideation and attempts was also examined. Fewer Hispanics reported suicide ideation (8.8% vs. 18.9%; p less than .001) and suicide attempts (3.2% vs. 5.1%; p less than .001) than non-Hispanic whites. More women of both ethnic groups reported suicide attempts than men of either ethnic group (p less than .001). Disrupted marital bonds were typically associated with higher rates of ideation and attempts. Individuals with any DIS diagnosis were more than four times as likely to think about killing themselves (p less than .01) and more than seven times as likely to attempt suicide (p less than .01) as those without a psychiatric disorder.

Creative productivity and age: A mathematical model based on a two-step cognitive process

It is argued that several empirical aspects of the relation between age and productivity can be explained by hypothesizing a simple two-step model of the creative process. Such a hypothesis permits a delayed single-peak function to result from an underlying process of constantly decelerating decay. The derived equation describes creative productivity as a function of individual age. The equation is not only shown to be consistent with empirical data on the relation between age and achievement, but additionally several important empirical predictions and theoretical consequences are inferred from the model. For instance, the model (a) maintains that the age curves may be largely the intrinsic outcome of cognitive processes rather than the extrinsic effect of developmental changes or sociological influences; (b) predicts the explanatory superiority of professional over chronological age; (c) explains the observed positive intercorrelation among creative precociousness, productivity, and longevity in terms of their mutual dependence upon individual differences in creative potential; and (d) provides a substantive basis for interpreting the variation in age peaks across disciplines by introducing the concepts of ideation rate, elaboration rate, and creative half-life. Tests to confirm or disconfirm the theoretical model are also proposed.
