A nonrandom sample of North American cases of sudden mass assault by a single individual (SMASI, n = 30) is compared with a nonrandom sample of Laotian amok cases (n = 18) and other amok studies. Perpetrators in both studies show evidence of social isolation, loss, depression, anger, pathological narcissism, and paranoia, often to a psychotic degree. The term "innovative perpetrator" is reintro...

A review of the literature reveals strong support for the construct validity of interpretations based on scores obtained with the original and more recent versions and/or variants of the South Oaks Gambling Screen (SOGS). Criticisms of the SOGS are shown to lack merit, to be offset by more important criteria, or to be no longer relevant. The evidence reviewed indicates that the construct of pat...

As there is a lack of evidence attesting the equivalent item functioning across genders for the most employed instruments used to measure pathological gambling in adolescence, the present study was aimed to test the gender invariance of the Gambling Behavior Scale for Adolescents (GBS-A), a new measurement tool to assess the severity of Gambling Disorder (GD) in adolescents. The equivalence of ...

There is no doubt that jealousy is a source of great personal misery and an emotion with far-reaching social consequences. For example, jealousy is frequently implicated as a factor in relationship dissolution, spousal abuse and even murder (Daly & Wilson, 1988; Harris, 2003a). Despite its destructive side, jealousy also may have some positive effects for individuals and relationships. For exam...

Stephen M. Weiss* Sherri L. Loubier Gambling behaviors in current athletes, former athletes and non-athletes were examined. Gambling tendencies were determined from participants' responses on the South Oaks Gambling Screen (SOGS). A delayed competitive effect among athletes that might surface in the form of pathological gambling was investigated. To test this novel theory, participants were div...

Lack of a suitable measuring device hampered the empirical study of narcissism until Raskin and Hall (1979) developed the Narcissistic Personality Inventory (NPI). The NPI possesses desirable psychometric properties, and in this article I used the scale in a variety of studies. Factor analysis of the scale replicated the four-factor solution found by Emmons (1984): Leadership/Authority, Self-Ab...

Bereavement-induced grief and psychological intervention are important social issues and worthy of greater attention from researchers and clinicians. Here, we review currently available measures of grief and discusses the differentiation of normal grief reaction from pathological grief and major depression. Finally, we propose future directions for research on the development of new grief measu...

INTRODUCTION Few studies have examined the impact of pathological gambling on quality of life especially in the Asian context. The aim of the current study was to examine the quality of life in pathological gamblers in a multiracial population in Singapore and we hypothesised that those with pathological gambling would have poorer quality of life as compared to controls. MATERIALS AND METHODS...

Pathological gambling is one manifestation of impulse control disorders. The biological underpinnings of these disorders remain elusive and treatment is far from ideal. Animal models of impulse control disorders are a critical research tool for understanding this condition and for medication development. Modeling such complex behaviors is daunting, but by its deconstruction, scientists have rec...

Anemia has a great impact on cognitive development and physical growth in preschool-aged children.1 In Brazil, anemia rates in children vary according to region, age group and sample.2–4 The present study measured the prevalence of anemia in a representative sample of 2673 schoolchildren enrolled in the first and second grades (6 and 7 years old) of 40 schools in the city of São José dos Campos...
