Initial validation of the Psychobiosocial States in Physical Education (PBS-SPE) scale
The purpose of this cross-sectional investigation was to examine the item characteristics, factor structure, reliability, convergent validity, and nomological validity of the Psychobiosocial States in Physical Education (PBS-SPE) scale. In Study 1, a sample of 1,030 students (582 girls and 448 boys, 10 to 19-year-olds), drawn from middle or high schools, rated the intensity of the 20 items version of the PBS-SPE scale thinking about the feelings they had usually experienced in physical education classes. In Study 2, an additional sample of 1,025 students (578 girls, 447 boys, 10 to 19-year-olds), rated the 16 items of the final version of the scale. Two subsamples also completed an affectiv…
Student intention to engage in leisure-time physical activity: The interplay of task-involving climate, competence need satisfaction and psychobiosocial states in physical education
Grounded in achievement goal theory and basic psychological needs theory, the aim of this study was to examine the impact of the interaction of perceived motivational climate in physical education with psychological needs satisfaction (relatedness, competence and autonomy) and psychobiosocial states on student intention to engage in leisure-time physical activity. Participants ( N = 470 Italian students, 287 boys and 183 girls, aged 16–19 years) completed the Teacher-Initiated Motivational Climate in Physical Education Questionnaire, the Psychological Needs Satisfaction Scale in Physical Education, the Psychobiosocial States Questionnaire, and a measure of intention to engage in leisure-tim…
Self-efficacy and enjoyment of physical activity in children: factorial validity of two pictorial scales.
BackgroundSelf-efficacy and enjoyment are two main constructs proposed within many motivational theories in any human endeavor, sport and physical activity included.MethodsThe purpose of this study was to examine the factor structure of two pictorial scales measuring self-efficacy and enjoyment levels in a sample of 14,035 Italian schoolchildren (7,075 boys and 6,960 girls, 6- to 7-year-olds). An important feature of the two scales is that they are in a pictorial format in order to prompt a straightforward understanding in children. The whole sample was randomly split in two subsamples according to gender and age and the factor structure of the measures was examined across subsamples.Result…
Machine Learning for Early Diagnosis of ATTRv Amyloidosis in Non-Endemic Areas: A Multicenter Study from Italy
Background: Hereditary transthyretin amyloidosis with polyneuropathy (ATTRv) is an adult-onset multisystemic disease, affecting the peripheral nerves, heart, gastrointestinal tract, eyes, and kidneys. Nowadays, several treatment options are available; thus, avoiding misdiagnosis is crucial to starting therapy in early disease stages. However, clinical diagnosis may be difficult, as the disease may present with unspecific symptoms and signs. We hypothesize that the diagnostic process may benefit from the use of machine learning (ML). Methods: 397 patients referring to neuromuscular clinics in 4 centers from the south of Italy with neuropathy and at least 1 more red flag, as well as undergoin…
