On compound and iterated conditionals
2021
We illustrate the notions of compound and iterated conditionals introduced, in recent papers, as suitable conditional random quantities, in the framework of coherence. We motivate our definitions by examining some concrete examples. Our logical operations among conditional events satisfy the basic probabilistic properties valid for unconditional events. We show that some, intuitively acceptable, compound sentences on conditionals can be analyzed in a rigorous way in terms of suitable iterated conditionals. We discuss the Import-Export principle, which is not valid in our approach, by also examining the inference from a material conditional to the associated conditional event. Then, we illus…
VALIDITY AND CREDIBILITY OF A CHILD’S TESTIMONY OF SEXUAL ABUSE: A CASE REPORT
2012
The allegation by a child victim of sexual abuse is, in many cases, the most important evidence of wrongdoing, especially in absence of medical or physical evidence or confes-sions of guilt. The Rorschach inkblot test is a projective personality assessment technique used to evaluate child witnesses. We report a case of three girls allegedly abused by the father, in which the psychometric evaluation with the Rorschach test did not give credibility to the testimony of the chil-dren. When interrogating a minor, it is very difficult to distinguish between a true and a lie. Indeed, many different elements can affect the dialogue, such as the child’s age, the events being discussed, interrogation…
Traducción y validación preliminar del Cuestionario de Adicción al Sexo en jóvenes
2016
Sex addiction is a pathology that starts in the adolescence or the early adulthood and has an important impact on social and personal development. Early detection is a key issue, so the aim of this study was to adapt and validate one of the most employed questionnaires for its assessment: the Sexual Addiction Screening Test. For this purpose, 600 young people completed the study surveys. Through a factor analysis, we found that the SAST was composed by 4 subscales that explained 38.38% of the variance. Furthermore, reliability and convergent validity values supported its employment in the assessment of sex addiction. Therefore, SAST is now one of the available resources for the assessment o…
Preliminary evaluation of a short version questionnaire for Executive Functioning Self-Report (EF-SR)
2020
The aim of the present study is the development and the evaluation of preliminary psychometric characteristics of a short form self-report questionnaire to assess executive functioning (EF). The research was conducted in a sample of 316 Italian children that attended primary or secondary schools, with an age range between 7 and 11. EFA showed that Executive Functioning Self-Report (EF-SR) is composed of eleven items that are adequately represented by a single factor that characterizes the total score of the EFs. Furthermore, preliminary analyses showed an adequate level of skewness and kurtosis, of internal reliabilities, and test-retest reliability. Finally, the EF-SR showed positive moder…
Unreliability of the dot probe task
2005
The dot probe task is a widely used measure of attention allocation to threatening stimuli. The present two studies examine the reliability of different versions of this task using words as well as pictures as stimulus material. Estimates of both internal consistency and retest reliability over one week lead to the conclusion that the dot probe task is a completely unreliable measure of attentional allocation in non‐clinical samples. This unreliability may explain the inconsistent findings for the dot probe task as reported in the literature. Copyright © 2005 John Wiley & Sons, Ltd.
Does the Implicit Association Test for assessing anxiety measure trait and state variance?
2004
The stability of the Implicit Association Test for assessing anxiety (IAT‐Anxiety) is lower than its internal consistency, indicating that the IAT‐Anxiety measures both stable and occasion‐specific variance. This suggests that the IAT‐Anxiety may be not only a valid measure of trait anxiety but also one of state anxiety. To test this assumption, two studies were conducted in which state anxiety was experimentally induced by a public speaking task. However, both studies showed that the IAT‐Anxiety score did not change when a state of anxiety was induced. Thus, it seems that occasion‐specific factors other than variations in state anxiety lead to occasion‐specific variance in the IAT‐Anxiety…
The assessment of susceptibility to emotional contagion: A contribution to the Italian adaptation of the “Emotional Contagion Scale”
2013
The Emotional Contagion Scale (ECS; Doherty, 1997) is a self-report instrument assessing susceptibility to emotional contagion. The study was aimed at examining its dimensionality, reliability, and validity in the Italian context. It was completed by 541 young adults (45% men) in Study 1 and 649 young adults (40% men) in Study 2. The results of a series of confirmatory factor analyses showed that a bi-factor model, with one general factor and four specific factors was supported. The general and specific factors resulted differently related to self-other differentiation, empathy, emotional fragility, masculinity, and femininity. Notwithstanding, the results posited some questions about the E…
Reliability of Implicit Self–Esteem Measures Revisited
2011
This study investigated the internal consistencies and temporal stabilities of different implicit self–esteem measures. Participants ( N = 101) responded twice—with a time lag of 4 weeks—to five different tasks: the Implicit Association Test (IAT), the Brief Implicit Association Test (BIAT), the Affective Priming Task (APT), the Identification–Extrinsic Affective Simon Task (ID–EAST) and the Name–Letter Task (NLT). As expected, the highest reliability coefficients were obtained for the self–esteem IAT. Importantly, the internal consistencies and the temporal stabilities of the APT, the ID–EAST, and the NLT were substantially improved by using material, structural, and analytic innovations.…
Predictive value of the Merrill-Palmer-R Scale applied during the first year of live
2016
Resumen basado en el de la publicación Títulos, resumen y palabras clave en inglés y español El valor predictivo de una escala de desarrollo utilizado durante el primer año de vida es de gran interés en la planificación de las intervenciones tempranas. El valor predictivo de un instrumento es la probabilidad de acertar el diagnóstico de trastorno o retraso en el desarrollo de un niño. Se analizaron las puntuaciones de escala Merrill-Palmer-R (MP-R) en una muestra de 291 niños menores de un año de la Comunidad Valenciana. A pesar de que no se distribuyen normalmente las puntuaciones de la escala MP-R en esta muestra, los resultados predichos eran buenos. Además, las puntuaciones de desarroll…
Assessment of students' situation-specific classroom engagement by an InSitu Instrument
2016
The present study aims to expand the current understanding of engagement by examining variations in students' situation-specific engagement in lower secondary school. In addition, the validity and reliability of a new situation-specific InSitu Instrument were examined. The sample consisted of 1809 Finnish students attending Grade 7. The students filled in mobile ratings on their lesson-specific engagement after lessons. Furthermore, they answered questionnaires concerning their overall engagement, achievement beliefs, and task values in math and literacy. The results showed substantial variation within and between students in situational engagement. A five-factor structure was identified fo…
