Ecological Validity of the Inventory of Problems-29 (IOP-29): an Italian Study of Court-Ordered,Psychological Injury Evaluations Using the Structured Inventory of Malingered Symptomatology (SIMS) as Criterion Variable

The Inventory of Problems-29 (IOP-29; Viglione, Giromini, & Landis, Journal of Personality Assessment, 99(5), 534–544, 2017) is a 29-item, recently published, self-administered test aimed at assessing the credibility of various symptom presentations. Although available research strongly supports the use of this symptom validity test in malingering-related contexts, to date, only few studies have analyzed data from real-life forensic evaluations. To fill this gap and explore ecological and convergent validity, the current study analyzed data from 74 court-ordered evaluations aimed at establishing the possible presence of psychological injury. Such evaluations are high-stakes situations in which exaggeration or malingering occur relatively often. We used a research-supported and popular symptom validity test, i.e., the Structured Inventory of Malingered Symptomatology (SIMS; Smith & Burger, Journal of the American Academy on Psychiatry and Law, 25:180–183, 1997), as our criterion variable. The IOP-29 produced excellent area under the curve (AUC) values of .98 with a recommended SIMS total score cutoff (≥ 17) and .99 when eliminating too-close-to-classify cases (Rogers & Bender, 2018) and very large Cohen’s d effect sizes of 2.98 and 3.59, respectively. Crucially, when implementing established cut scores from previous research, the IOP-29 yielded very high specificity and sensitivity rates, and the predictions from the two tests were strikingly similar. Taken together, these findings support the strong convergent validity of the IOP-29 and its utility in applied clinical and forensic settings.     

Silence of the Innocents: Undocumented Immigrants’ Underreporting of Crime and their Victimization

Do undocumented migrants underreport crimes to the police in order to avoid being deported? And do criminals exploit such vulnerability? We address these questions using victimization surveys and administrative data around the 1986 U.S. immigration amnesty. The amnesty allows us to solve two major identification issues that have plagued this literature: migrants’ legal status is endogenous and unobserved. The results show that the reporting rate of undocumented immigrants is 17 percent, which limits the immigrants’ ability to protect some of their fundamental human rights. However, right after the 1986 amnesty, which disproportionately legalized individuals of Hispanic origin, crime victims of Hispanic origin show enormous improvements in reporting behavior. The implied increase in the reporting rate by amnesty applicants is close to 20 percentage points.     

Wage labour and capitalism: a comparative and historical analysis of Eritrea and Kenya

Abstract

This paper seeks to explain the development of capitalism in Eritrea and Kenya from a labour history perspective. Indeed, the assumption in this research is that capitalism can only be explained by taking into consideration free wage labour as one of the sine qua non conditions for the existence of the capitalist mode of production. Therefore, the article looks at the paradigmatic socio-economic shifts: from unfree to free labour, from free to precarious labour and from unfree to precarious labour. These are the result of the complicated relationship that exists between capital and labour. The point of departure of the analysis is the Nieboer-Domar hypothesis on the structural origins of slavery, which despite severe criticism, it has been largely remained unchallenged until the present. In Eritrea, colonised by Italy, and Kenya, colonised by England, free wage labour fully developed between the nineteenth and twentieth century. This could be considered the era of the advent of capitalism, with the advent, for a fraction of the working population, of labour relations based on wages. The precarisation of life of free wage workers is also partially analysed in this article.     

Ritual homicide during dissociative trance disorder

A case report is described of a man who developed a single period of recurrent episodes of dissociative trance disorder (DTD) during a family stress. The cultural environment was permeated by thoughts and beliefs in magic. During one trance state, the man performed an exorcism on the 6-month-old baby of his brother-in-law, and the baby died from cerebral hemorrhage. In the 5-year follow-up, no other episodes of DTD developed, and the man is serving an 18-year sentence.
