Is IQ in Childhood Associated with Suicidal Thoughts and Attempts? Findings from The Mater University Study of Pregnancy and Its Outcomes

This study explores associations of IQ at age 14 with adult symptoms of suicidal thoughts and attempts at age 21. Analysis was based on the Mater University Study of Pregnancy and its outcomes, an Australian prospective birth cohort study started in Brisbane Australia in 1981. We assessed associations with suicide thoughts, plans, and attempts. We used two measures of IQ: the Raven's Standard Progressive Matrices and the Wide Range Achievement Test. In multivariable analyses, there was an inverse association between Raven's IQ and suicide thoughts, plans, and attempts, but no strong evidence of an association between the WRAT3 and the three suicidal items. Specific aspects of intelligence may be associated with suicidal thoughts, plans, and attempts.     

Distinguishing Between Subgroups of Adolescents Who Self‐Harm

The differences in factors associated with subgroups of adolescents in the continuum of deliberate self‐harm (DSH) phenomena were investigated. In an anonymous self‐report survey of 6,020 adolescents aged 15 and 16 years, 3.2% of adolescents (5.3% females, 1.3% males) reported DSH with intent to die, 2.8% (4.3% females; 1.5% males) reported DSH without intent to die, and 15% (22.4% females; 8.5% males) reported thoughts of DSH without acts. Regression analysis indicated considerable overlap in vulnerability factors along the spectrum of DSH thoughts and acts. A uniquely distinct relationship was found between DSH of a friend and DSH without intent to die on one hand and DSH of a family member with DSH with intent to die on the other. Results indicate that familial and nonfamilial social influences on DSH behavior may be important in designing prevention programs and that educational programs for the promotion of psychological well‐being may be helpful for adolescents at any point along the spectrum of DSH that was examined.     

Neurocognitive influences on health behavior in a community sample.

CONTEXT: Dominant models of individual health behavior omit biological variables entirely and are composed almost exclusively of social-cognitive and conative variables. Research from the neurosciences suggests a role for brain function in explaining behaviors that require active self-regulation for consistent performance. However, the association between brain function and health behavior is underexplored. OBJECTIVE: To examine the predictive power of executive function for 2 health risk behaviors and 2 health protective behaviors in healthy adults. DESIGN: A cross-sectional community sample (N = 216) of adults 20-100 years of age were administered a battery of neuropsychological tests and completed self-report questionnaires regarding their health practices. It was hypothesized that poor performance on neuropsychological tests tapping executive function would be associated with poor health behavior tendencies. RESULTS: Errors on the Stroop task were positively associated with health risk behavior and negatively associated with health protective behavior after controlling for demographics, education, and IQ. CONCLUSION: Executive function is associated with health behavior tendencies. If the association is causal, explanatory models of individual health behavior should be revised to account for individual differences in biologically imbued self-regulatory abilities.     

Temperamental Vulnerability and Suicide Risk After Attempted Suicide

The aim was to extend recent findings of suggested temperamental features in attempted suicide and to explore possible domains of vulnerability to suicide risk after attempted suicide. Fifty-four psychiatric inpatients hospitalized after a suicide attempt underwent lumbar puncture for analysis of CSF 5-HIAA concentration and also completed the Karolinska Scales of Personality (KSP) before discharge from the hospital. Suicide attempters scored high on Somatic Anxiety, Psychic Anxiety, and Muscular Tension, and low on Socialization, findings that support recent findings in suicide attempters followed up after an emergency room visit. Five patients committed early suicide, i.e., within 3 years, and the overall long-term suicide mortality after attempted suicide was 13%. There were significant correlations between survival time among early suicides and CSF 5-HIAA (r = .87;p = .054), and the following KSP scale t scores: Somatic Anxiety (r = ?.96;p < .05), Impulsivity (r = ?.88; p < .05), and Socialization (r = .90; p < .05). KSP Socialization showed correlations with CSF 5-HIAA (r = .89; p = .046) among the early suicides. Features of temperamental vulnerability to suicide risk after attempted suicide might involve anxiety proneness, impulsivity, low socialization, and low CSF 5-HIAA.     

The Interrelations of Agency,Depression, and Suicidal Ideation Among Older Adults

The high rates of suicide among older men are cause for concern, and have prompted the investigation of factors that might explain these elevated rates. The current research examined whether the gender role construct agency was associated with depression and suicidal ideation among older adults. The results, based on self‐report data from a sample of older Australian men (n = 69) and women (n = 90), indicated that depression mediated the relation between agency and suicidal ideation. In addition, for older men only, agency moderated the depression‐suicidal ideation relation. The results suggest that older adults, and particularly men, with low levels of agency should be the targets for interventions aimed at increasing levels of agency and improving mental health.     

Terrorism as Collective Communication: The Collective Communication Model of Terrorism (CCMT)

This paper proposes that the psychological and behavioral effects of terrorist threat can be understood as a collective communication process that occurs between terrorists and their potential victims. Based on classic communication theory, terrorists are regarded as the senders of a specific collective message (such as ‘stop oppressing our culture’); a terrorist incident as the collective message itself (through its performance, modality and targets); and the potential victims as its collective receivers (who interpret the intention of the attack as a function of their pre-existing attributes, such as traits or salient social identities). The perception of terrorism as a dynamic and interactive process between collective senders, messages and receivers opens new theoretical perspectives regarding whether (a) terrorism can be successful in reaching its collective aim; (b) if it is interpreted as rational or irrational; and (c) how to counteract the vicious, cyclical relationship between terrorism and counter-terrorism. Previous findings on the psychology of terrorism can be organized within this theoretical framework, and the psychological impact of varying attributes of the perpetrators (senders), incident (message), and the reactions of the potential victims (receivers) systematically investigated. A series of self-conducted studies are also reviewed and found to provide direct support for the collective communication model of terrorism.
