An Integrative Suicide Prevention Program for Visitor Charcoal Burning Suicide and Suicide Pact

An integrative suicide prevention program was implemented to tackle an outbreak of visitor charcoal burning suicides in Cheung Chau, an island in Hong Kong, in 2002. This study evaluated the effectiveness of the program. The numbers of visitor suicides reduced from 37 deaths in the 51 months prior to program implementation to 6 deaths in the 42 months post‐implementation period. The number of visitor suicide pacts decreased from 7 pacts (15 individuals) to 1 pact (2 individuals). No statistically significant differences in the numbers of visitor suicide attempts and resident suicides were observed in the two time periods. No statistically significant changes in visitor suicides during the study period were observed on the comparison islands. The consistency and timing of reduction in visitor suicides correlated with the development and delivery of the integrative program on the intervention island, suggesting a causal association between program delivery and reduction of visitor suicides. The possibility of displacement seems small because there was no increase in visitor suicides on the comparison islands during the study period. This integrative approach in preventing target‐specific suicides may serve as an example for other communities to develop suicide prevention programs that make use of the existing local resources.     

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.     

The impact of an 8-day intensive treatment for adolescent panic disorder and agoraphobia on comorbid diagnoses

Previous research findings have shown positive effects of cognitive-behavioral therapy for primary anxiety disorders as well as for nonprimary, co-occurring anxiety disorders. In this study, we analyzed data from an existing randomized controlled trial of intensive treatment for panic disorder with or without agoraphobia (PDA) to examine the effects of the treatment on comorbid psychiatric diagnoses. The overall frequency and severity of aggregated comorbid diagnoses decreased in a group of adolescents who received an 8-day treatment for PDA. Results suggest that an 8-day treatment for PDA can alleviate the symptoms of some specific comorbid clinical diagnoses; in particular specific phobias, generalized anxiety disorder, and social phobia. These findings suggest that an intensive treatment for PDA is associated with reductions in comorbid symptoms even though disorders other than PDA are not specific treatment targets.     

Inhibitory control differentiates rare target search performance in children

Age-related differences in rare-target search are primarily explained by the speed-accuracy trade-off, primed responses, or decision making. The goal was to examine how motor inhibition influences visual search. Children pressed a key when a rare target was detected. On no-target trials, children withheld reactions. Response time (RT), hits, misses, correct rejection, and false alarms were measured. Tapping tests assessed motor control. Older children tapped faster, were more sensitive to rare targets (higher d'), and reacted more slowly than younger ones. Girls outperformed boys in search sensitivity but not in RT. Motor speed was closely associated with hit rate and RT. Results suggest that development of inhibitory control plays a key role in visual detection. The potential implications for cognitive-motor development and individual differences are discussed.     

Processing Speed and Neurodevelopment in Adolescent-Onset Psychosis: Cognitive Slowing Predicts Social Function

Onset of psychosis may be associated with abnormal adolescent neurodevelopment. Here we examined the neurocognitive profile of first-episode, adolescent onset psychosis (AOP) as compared to typically developing adolescents, and asked whether neurocognitive performance varied differentially as a function of age in the cases compared with controls. A comprehensive neuropsychological battery was administered to 35 patients experiencing a first-episode of a DSM-IV psychotic disorder and to 31 matched controls. Clinicians also rated subjects’ social and role functioning, both at the time of neuropsychological assessment and 1 year later. Although patients displayed a wide range of impairments relative to controls, their most pronounced deficits included verbal memory, sensorimotor dexterity and cognitive processing speed. Among these, only processing speed showed a significant group-by-age interaction, consistent with an aberrant developmental course among AOP patients. Processing speed also accounted for substantial variance in other areas of deficit, and predicted social functioning 1 year later. AOP patients fail to show normal age-related increases in processing speed, which in turn predicts poorer functional outcomes. This pattern is consistent with the view that adolescent brain developmental processes, such as myelination, may be disrupted in these patients.     

Autonomous forms of motivation underpinning injury prevention and rehabilitation among police officers: An application of the trans-contextual model

The present study applied the trans-contextual model (TCM) to understand the motivational processes underpinning workers?? injury prevention and rehabilitation intentions and behavior. Full-time police officers (N?=?207; M age?=?37.24, SD?=?9.93) completed questionnaire measures of the TCM variables. Covariance-based SEM for the full sample revealed that the effect of autonomy support from supervisor on autonomous motivation for injury prevention (M-injury) was fully mediated by autonomous work motivation (M-work), and the effect of M-injury on intention was fully mediated by attitude and subjective norm. Variance-based SEM for the 87 participants who had recent occupational injury showed that the effect of autonomy support from supervisor on autonomous treatment motivation (M-treatment) was partially mediated by M-work, and the effect of perceived autonomy support from physician on treatment adherence was fully mediated by M-treatment. There was no effect of treatment adherence on recovery length. Findings support the motivational sequence of the TCM in an occupational context.     

Enacting modesty in Chinese culture: The joint contribution of personal characteristics and contextual features

This research revealed the joint impact of personality traits, social axioms, role relationships and the privacy of social situations on the enactment of three types of modesty, namely, avoiding attention, self‐effacement, and enhancement of others, among Hong Kong Chinese teenage females. The modest personality trait was found to relate positively to these modest behaviours. An individual's belief in reward for application significantly predicted self‐effacement, and the belief in social cynicism significantly predicted avoiding attention and enhancement of others. Contextual variables as measured by the role relationships and the privacy of the social setting also significantly affected the levels of these modest behaviours.     

Juvenile homosexual homicide

Limited information exists on juvenile homosexual homicide (JHH), that is, youths who perpetrate sexual homicides against same-sex victims. Only a handful of cases from the United States and internationally have been described in the literature. This study, the first of its kind, examines the epidemiology, victimology, victim-offender relationship, and weapon-use patterns in JHH offenders using a large U.S. database on homicide spanning three decades. The data for this study were derived from the Federal Bureau of Investigation's Supplementary Homicide Reports (SHRs) for the years 1976 through 2005. A total of 93 cases of JHH were identified. On average, three of these crimes occurred annually in the U.S., and there was a marked decline in its incidence over the study period. Ninety-five percent were male offender-male victim cases and 5% were female offender-female victim cases. JHH offenders were over-represented amongst all juvenile sexual murderers, similar to their adult counterparts. The majority of these boys were aged 16 or 17 and killed adult victims. They were significantly more likely to kill adult victims than other age groups, to be friends or acquaintances of the victims, and to use contact/edged weapons or firearms. Most offenders killed same-race victims, although Black offenders were significantly more likely than White offenders to kill interracially. A case report is provided to illustrate JHH. Further research is needed to promote our understanding of the pathogenesis, etiology, and associated risk factors for this aberrant form of murder by children.
