The Dimensions of Facebook Addiction as Measured by Facebook Addiction Italian Questionnaire and Their Relationships with Individual Differences
2017
Abstract The studies reported analyze the factorial structure of Facebook Addiction Italian Questionnaire (FAIQ), a variant of 20-item Young's Internet Addiction Test (IAT). In Study 1, we tested FAIQ psychometric properties using exploratory factor analysis (EFA). In Study 2, we performed a confirmatory factor analysis (CFA) to verify the FAIQ factorial structure identified through EFA. Results from CFA confirm the presence of a four-factor model accounting for 58 percent of total variance, plus a general higher order factor that best fits the data. Further relationships between FAIQ factor scores, personality, and Facebook usage have been explored.
A study of temporal estimation from the perspective of the Mental Clock Model.
2009
M. Cardaci's (2000) Mental Clock Model maintains that a task requiring a low mental workload is associated with an acceleration of perceived time, whereas a task requiring a high mental workload is associated with a deceleration. The authors examined the predictions of this model in a musical listening condition in which musical pieces were audible in several structural complexities. To measure the effects of musical complexity on time estimation, the authors used retrospective and prospective time-estimation paradigms. For the retrospective paradigm, the authors invited participants to listen to a musical piece and then estimate its duration. For the prospective paradigm, the authors invit…
Frequency format facilitates reasoning in simple numerical tasks.
2005
This study examined whether it is easier to reason in terms of frequencies or with percentages for simple numerical tasks. Research on probabilistic reasoning has shown that humans can draw correct inferences when problems are presented in terms of natural frequencies but not when in percentages. Whether the same effect can be observed in other numerically simple tasks which are not probabilistic was studied with 40 undergraduate students who volunteered for the experiment (13 men, 27 women; M age of 23 yr.). In a simple numerical task involving frequencies or percentages ( N = 20), their performance showed representation in frequencies facilitates the task.
Cardiovascular Management Self-efficacy: Psychometric Properties of a New Scale and Its Usefulness in a Rehabilitation Context.
2015
Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. Background: Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. Purpose: The aims of this study were to present a new scale measuring self-efficacy beliefs in managing CVD and to examine its psychometric properties. Methods: The study involved 172 patients (mean age = 66.4…
Predicting depression from illness severity in cardiovascular disease patients: self-efficacy beliefs, illness perception, and perceived social suppo…
2014
Background: Many studies have investigated the relationships between cardiovascular diseases and patients' depression; nevertheless, few is still known as regard the impact of illness severity on depression and whether psychosocial variables mediate this association. Purpose: The aim of this study is to investigate the putative mediating role of illness representations, self-efficacy beliefs, and perceived social support on the relationship between illness severity and depression. Methods: A total of 75 consecutive patients with cardiovascular disease (80 % men; mean age=65.44, SD=10.20) were enrolled in an Italian hospital. Illness severity was measured in terms of left ventricular ejectio…
The influence of illness severity on health satisfaction in patients with cardiovascular disease: The mediating role of illness perception and self-e…
2015
The importance of psychological factors in improving conditions of cardiovascular disease (CVD) patients is stressed by the guidelines for their prevention and rehabilitation, but little is known about the impact of illness severity on patients well-being, and on the psychosocial variables that may mediate this association. The aim of this study was to investigate the role of illness perception and self-efficacy beliefs on the relationship between illness severity and health satisfaction in 75 CVD patients undergoing rehabilitation (80% men; mean age = 65.44) at the St. Luca Hospital, Istituto Auxologico Italiano, Milan, Italy. Illness severity was measured in terms of left ventricular ejec…
Is more choice always worse? Age differences in the overchoice effect
2015
ABSTRACTCurrent research on the overchoice effect has been mainly conducted from an adult point of view and with adult subjects. This study investigates whether children, adolescents, and seniors suffer the same negative consequences as adults when facing an overabundance of choice. Findings showed that the overchoice effect did not equally extend to all age groups. While adolescents were affected by the phenomenon in a very similar way as adults, children and seniors suffered fewer negative consequences of an overabundance of choice. Theoretical and practical implications are discussed.

Robotica e Mondi Virtuali: un Laboratorio di Edutainment con Lego Mindstorm e Kodu Game Lab
2014
Un gruppo di studenti del primo anno della scuola secondaria di primo grado è stato coinvolto in uno studio di ricerca-azione volto ad esplorare le abilità cognitive coinvolte e stimolate dall’uso di tecnologie quali LEGO® Mindstorm e Kodu Game Lab (KGL). I risultati dello studio dimostrano che l’utilizzo di queste due tecnologie richiede, negli alunni coinvolti nel laboratorio, l’applica- zione di processi cognitivi e competenze scolastiche differenti. Nello specifico, LEGO® Mindstorm sollecita maggiormente l’impiego di abilità di ragiona- mento logico-deduttivo, la capacità di elaborare velocemente target visivi, il problem solving geometrico, e la lettura e comprensione del testo-. L’uso…
A multicenter randomized trial for quality of life evaluation by non-invasive intelligent tools during post-curative treatment follow-up for head and…
2023
Patients surviving head and neck cancer (HNC) suffer from high physical, psychological, and socioeconomic burdens. Achieving cancer-free survival with an optimal quality of life (QoL) is the primary goal for HNC patient management. So, maintaining lifelong surveillance is critical. An ambitious goal would be to carry this out through the advanced analysis of environmental, emotional, and behavioral data unobtrusively collected from mobile devices. The aim of this clinical trial is to reduce, with non-invasive tools (i.e., patients' mobile devices), the proportion of HNC survivors (i.e., having completed their curative treatment from 3 months to 10 years) experiencing a clinically relevant r…
