    ABSTRACT: A sample of 87 Turkish undergraduate students was administered scales to measure hopelessness, problem-solving skills, emotion dysregulation, and psychiatric symptoms. All of the scores from these scales were strongly associated. In a multiple regression, hopelessness scores were predicted by poor problem-solving skills and emotion dysregulation.

    ABSTRACT: Three series of suicides were examined for evidence of clustering: suicides on the Hong Kong subway (1979-1989), suicides from the Golden Gate Bridge (1999-2009), and suicides in the Wayne County Jail (1967-1992). The inter-suicide intervals were examined for their fit to a random Poisson distribution and found not to differ significantly, indicating that there was no evidence for clustering.

    ABSTRACT: In a previous article in this journal, Gunn, Lester and McSwain provided evidence that the ten warnings signs for suicide proposed by the American Association for Suicidology are valid for predicting suicidal ideation and behavior A video posted on YouTube by a 15-year-old girl scored 8-9 out of 10 for these signs. Thirty-nine days after positing the video, the girl killed herself.

    ABSTRACT: The presence of 10 warning signs for suicide proposed by the American Association of Suicidology was compared in 215 postings on a suicide forum and 94 postings on a self-injury forum. The suicide forum postings received a higher score on the 10 signs than the self-injury forum postings, and significant differences were found for 6 of the 10 signs: suicidal ideation, purposelessness, trapped, hopelessness, withdrawal, and, in the reverse direction, recklessness. Overall, the findings support the usefulness of the warning signs in identifying suicidal individuals.

    ABSTRACT: Joiner's interpersonal theory of suicide postulates that suicide occurs because of thwarted belongingness and perceived burdensomeness, combined with a capability for committing suicide. The present study examines the frequency of the presence of the themes of thwarted belongingness and perceived burdensomeness in suicide notes. A total of 261 suicide notes from 1091 consecutive completed suicides in Tasmania were rated for the presence of thwarted belongingness and perceived burdensomeness. Contrary to the theory, few suicide notes were found to include perceived burdensomeness (10.3%) and thwarted belongingness (30.7%), and only 4.2% had both themes. The notes of women more often contained the theme of perceived burdensomeness, while the notes of younger suicides more often contained the theme of thwarted belongingness. Joiner's theory of suicide may apply to only a small percentage of suicides who leave suicide notes.

    ABSTRACT: The suicide rates of 18 European nations were associated with the proportion of sad words in the lyrics of their national anthems as well as the gloominess of the music. It is suggested that a possible suicide prevention tactic might involve changing the music and lyrics of national anthems.

    ABSTRACT: In a sample of 115 undergraduates, women expressed more sympathy for hypothetical attempted suicides than did men, but not more empathy or agreement with the actions. A history of considering suicide was not associated with judgments about attempting suicide.

    ABSTRACT: The 10 warning signs for suicide, encapsulated in the mnemonic IS PATH WARM, did not differentiate between genuine suicide notes and those written by people simulating a suicidal crisis or between notes written by completed suicides and those written by attempted suicides.

    ABSTRACT: In a sample of 18 European nations, suicide rates were positively associated with the proportion of low notes in the national anthems and, albeit less strongly, with students' ratings of how gloomy and how sad the anthems sounded, supporting a hypothesis proposed by Rihmer.

    ABSTRACT: In order to help crisis counselors assess clients for their suicidal risk, in 2003 the American Association of Suicidology proposed ten warning signs, memorized through the acronym IS PATH WARM However, little research has been done investigating their effectiveness for predicting suicidal behavior The present study compared (1) suicide ideators with non-suicide ideator controls and (2) suicide ideators with suicide attempters on six of the IS PATH WARM warning signs, along with depression in the past year, marital status, and gender With regards to the comparison between suicide ideators and non-ideators, all variables but gender; abuse of alcohol in the past year, and anxiety in the past year were predictive of suicide ideation. However, when comparing suicide ideators who had not made a suicide attempt with those who had, only anger/aggression, depression in the past year, and marital status were predictive of a suicide attempt.

    ABSTRACT: In a sample of 115 undergraduates, no association was found between a measure of moral development and the perception of attempted suicides. For the 85 women in the sample, a higher moral development score was associated with less approval of physician-assisted suicide.
