Hikikomori: dal Giappone all’Occidente tra psicopatologia e manifestazione culturale

Hikikomori is a condition of severe social withdrawal in which people shut themselves off from society and stay alone in their homes/rooms for at least six months. The first part of this paper reports on how Hikikomori has been widely conceptualized as a clinical (i.e., psychiatric or psychological) condition. From this point of view, temperament, emotional or familiar factors have been often proposed to explain Hikikomori. The second part of this paper focuses on the thesis that Hikikomori mainly depends on historical-cultural circumstances that have prevailed in the Japanese context, and suggests that it may be best conceptualized as a form of social protest (instead of as a psychopathological condition)

Application of the Double Monotonicity Model to Polytomous Items. Scalability of the Beck Depression Items on subjects with eating disorders

This paper investigates the item scalability of the Beck Depression Inventory (BDI) in 252 subjects; 126 with and 126 without eating disorders. To do so, an order was established regarding the BDI items according to the clinical characteristics of the subjects with eating disorders. The nonparametric Item Response Theory (NIRT) model was applied to evaluate Monotone Homogeneity and Double Monotonicity of items, as well as the reliability of the scale in both groups. The results show that the order of the items is satisfied in the group with eating disorders, but not in the control group. Therefore, the results obtained allow the ordering of depression scores of subjects with eating disorders according to their clinical characteristics. This order is not valid for the depression scores of subjects who did not have eating disorders. It should be noted that the application of the Double Monotonicity model to polytomous items provides new and relevant information when compared to the data provided by the Classical Test Model. In addition, it is very useful for other items and subjects having certain characteristics

Obtaining Equations from the Proportional Odds Model to Set Multiple Cut Scores on a Test

From the proportional odds (PO) model, we obtain general equations to compute multiple cut scores on a test score. This analytical procedure is based on the relationship between a test score (X) and an ordinal outcome variable (Y) with more than two categories. Cut scores are established at the test scores corresponding to the intersection of adjacent category distributions. The application of this procedure is illustrated by an example with data from an actual study on eating disorders (EDs). In this example, two cut scores on the Eating Attitudes Test (EAT-26) are established in order to differentiate between three ordered categories: (1) asymptomatic, (2) symptomatic, and (3) eating disorder. Diagnoses were made from the responses to a self-report (Q-EDD) that operationalizes DSM-IV criteria for EDs. Alternatives to the PO model, when the PO assumption is rejected, are discussed
