OBJECTIVE The factor structure of the Sensation-Seeking Scale (SSS)-Form V was studied in 2 large French samples, using confirmatory factorial analyses (CFA) to test the 4-dimensional model of sensation seeking postulated by Zuckerman. METHOD The study included 769 healthy subjects and 659 patients who met the DSM-IV criteria for substance use disorders or eating disorders and completed the S...

Background and aims Recent research on problematic Facebook use has highlighted the need to develop a specific theory-driven measure to assess this potential behavioral addiction. The aim of the present study was to examine the factorial validity of the Problematic Facebook Use Scale (PFUS) adapted from Caplan's Generalized Problematic Internet Scale model. Methods A total of 1,460 Italian adol...

DESIGN Transversal and ex post facto retrospective study. Confirmatory factorial analysis, multifactorial invarianc...

BACKGROUND The Internet Addiction Test (IAT) is the most widely used questionnaire to screen for problematic Internet use. Nevertheless, its factorial structure is still debated, which complicates comparisons among existing studies. Most previous studies were performed with students or community samples despite the probability of there being more problematic Internet use among users of specific...

BACKGROUND The Strengths and Difficulties Questionnaire (SDQ) is a tool to measure the risk for mental disorders in children. The aim of this study is to describe the diagnostic efficiency and internal structure of the SDQ in the sample of children studied in the Spanish National Health Survey 2006. METHODS A representative sample of 6,773 children aged 4 to 15 years was studied. The data wer...

In this paper we present a natural and comprehensive generalisation of the standard factorial moments (F q) analysis of a multiplicity distribution. The Generalised Factorial Moments are defined for all q in the complex plane and, as far as the negative part of its spectrum is concerned, could be useful for the study of infrared structure of the Strong Interactions Theory of high energy interac...

BACKGROUND The Recalled Parental Rearing Behavior questionnaire (FEE, [1,2]) assesses perceived parental rearing behavior separately for each parent. An ultra-short screening version (FEE-US) with the same three scales each for the mother and the father is reported and factor-analytically validated. METHODS N = 4,640 subjects aged 14 to 92 (M = 48.4 years) were selected by the random-route sa...
