ABSTRACT The experience of a sudden urge to jump when in a high place has been speculated to be associated with suicidal ideation; however, scant data has informed this speculation. We termed this experience the high place phenomenon (HPP) and proposed that it stems from a misinterpreted safety signal (i.e., survival instinct). The present study aimed to assess the prevalence of the HPP, to provide evidence that the phenomenon is not exclusive to suicide ideators, and to explore the role of anxiety sensitivity in the phenomenon.
431 undergraduate college students completed online measures of lifetime frequency of experiencing the HPP, suicidal ideation, anxiety sensitivity, depressive symptoms, and history of mood episodes.
The HPP was commonly reported in the general population, even among participants with no history of suicidal ideation. There was a significant correlation between anxiety sensitivity and the HPP, and this relationship was moderated by level of current suicidal ideation. Particularly, the relationship between anxiety sensitivity and the HPP was potentiated among participants with low levels of suicidal ideation.
The cross-sectional design of the study limits the strength of the conclusions that can be drawn.
The HPP is commonly experienced among suicide ideators and non-ideators alike. Thus, individuals who report experiencing the phenomenon are not necessarily suicidal; rather, the experience of HPP may reflect their sensitivity to internal cues and actually affirm their will to live.

    ABSTRACT: A distinction is proposed between anxiety (frequency of symptom occurrence) and anxiety sensitivity (beliefs that anxiety experiences have negative implications). In Study 1, a newly-constructed Anxiety Sensitivity Index (ASI) was shown to have sound psychometric properties for each of two samples of college students. The important finding was that people who tend to endorse one negative implication for anxiety also tend to endorse other negative implications. In Study 2, the ASI was found to be especially associated with agoraphobia and generally associated with anxiety disorders. In Study 3, the ASI explained variance on the Fear Survey Schedule—II that was not explained by either the Taylor Manifest Anxiety Scale or a reliable Anxiety Frequency Checklist. In predicting the development of fears, and possibly other anxiety disorders, it may be more important to know what the person thinks will happen as a result of becoming anxious than how often the person actually experiences anxiety. Implications are discussed for competing views of the ‘fear of fear’.

    ABSTRACT: Risk factors for suicide attempts have rarely been studied comprehensively in more than one psychiatric disorder, preventing estimation of the relative importance and the generalizability of different putative risk factors across psychiatric diagnoses. The authors conducted a study of suicide attempts in patients with mood disorders, psychoses, and other diagnoses. Their goal was to determine the generalizability and relative importance of risk factors for suicidal acts across diagnostic boundaries and to develop a hypothetical, explanatory, and predictive model of suicidal behavior that can subsequently be tested in a prospective study. Following admission to a university psychiatric hospital, 347 consecutive patients who were 14-72 years old (51% were male and 68% were Caucasian) were recruited for study. Structured clinical interviews generated axis I and axis II diagnoses. Lifetime suicidal acts, traits of aggression and impulsivity, objective and subjective severity of acute psychopathology, developmental and family history, and past substance abuse or alcoholism were assessed. Objective severity of current depression or psychosis did not distinguish the 184 patients who had attempted suicide from those who had never attempted suicide. However, higher scores on subjective depression, higher scores on suicidal ideation, and fewer reasons for living were reported by suicide attempters. Rates of lifetime aggression and impulsivity were also greater in attempters. Comorbid borderline personality disorder, smoking, past substance use disorder or alcoholism, family history of suicidal acts, head injury, and childhood abuse history were more frequent in suicide attempters. The authors propose a stress-diathesis model in which the risk for suicidal acts is determined not merely by a psychiatric illness (the stressor) but also by a diathesis. This diathesis may be reflected in tendencies to experience more suicidal ideation and to be more impulsive and, therefore, more likely to act on suicidal feelings. Prospective studies are proposed to test this model.

    ABSTRACT: General population survey data are presented on the lifetime prevalence of suicide attempts as well as transition probabilities to onset of ideation, plans among ideators, and attempts among ideators either with or without a plan. Risk factors for these transitions are also studied. Data are from part II of the National Comorbidity Survey, a nationally representative survey carried out from 1990 to 1992 in a sample of 5877 respondents aged 15 to 54 years to study prevalences and correlates of DSM-III-R disorders. Transitions are estimated using life-table analysis. Risk factors are examined using survival analysis. Of the respondents, 13.5% reported lifetime ideation, 3.9% a plan, and 4.6% an attempt. Cumulative probabilities were 34% for the transition from ideation to a plan, 72% from a plan to an attempt, and 26% from ideation to an unplanned attempt. About 90% of unplanned and 60% of planned first attempts occurred within 1 year of the onset of ideation. All significant risk factors (female, previously married, age less than 25 years, in a recent cohort, poorly educated, and having 1 or more of the DSM-III-R disorders assessed in the survey) were more strongly related to ideation than to progression from ideation to a plan or an attempt. Prevention efforts should focus on planned attempts because of the rapid onset and unpredictability of unplanned attempts. More research is needed on the determinants of unplanned attempts.
