Well-being, distress and health status in a population of adolescent students

The present work explores the psychosocial issues emerging from a large cross-sectional study aimed to assess the prevalence, clinical manifestations, and psychosocial correlates of hyperandrogenism in a population of Italian high school students. Participants were 1804 adolescents, aged between 15 and 19 years, who volunteered to fill in a package of self-report questionnaires (including the Psychosocial Index, the Symptom Questionnaire and Ryff’s Psychological Well-Being scales for the assessment of psychological aspects) and undergo a comprehensive physical examination. Significant gender differences were found with regard to psychological distress, with females reporting higher scores compared with males, but not on well-being dimensions. The relationships of well-being to distress were found to be complex. Although inversely associated, well-being and ill-being appeared to be distinct domains of mental functioning. The evaluation of the moderating effects of well-being in the association between stress and psychological distress indicated that well-being may act as a protective factor, contributing to less pronounced psychological distress as stress levels increased. Higher rates of somatic complaints were found among current smokers. However, substance use (i.e., smoking and drug use) was also found to be positively associated with some well-being dimensions. A considerable number of participants were found to present with disordered eating symptoms, particularly females, and associated higher stress levels and lower quality of life. Sport activities were found to favourably affect psychological health. As to clinical signs of hyperandrogenism, a significant impairment in psychosocial functioning was found among females, whereas no effects on psychological measures could be detected among males. Subgroups of adolescents with distinct clinical and psychological characteristics could be identified by means of cluster analysis. The present study provides new insights into better understanding of the complex relationships between well-being, distress and health status in the adolescent population, with important clinical implications.

Investigating the learning potential of the Second Quantum Revolution: development of an approach for secondary school students

In recent years we have witnessed important changes: the Second Quantum Revolution is in the spotlight of many countries, and it is creating a new generation of technologies. To unlock the potential of the Second Quantum Revolution, several countries have launched strategic plans and research programs that finance and set the pace of research and development of these new technologies (like the Quantum Flagship, the National Quantum Initiative Act and so on). The increasing pace of technological changes is also challenging science education and institutional systems, requiring them to help to prepare new generations of experts. This work is placed within physics education research and contributes to the challenge by developing an approach and a course about the Second Quantum Revolution. The aims are to promote quantum literacy and, in particular, to value from a cultural and educational perspective the Second Revolution. The dissertation is articulated in two parts. In the first, we unpack the Second Quantum Revolution from a cultural perspective and shed light on the main revolutionary aspects that are elevated to the rank of principles implemented in the design of a course for secondary school students, prospective and in-service teachers. The design process and the educational reconstruction of the activities are presented as well as the results of a pilot study conducted to investigate the impact of the approach on students' understanding and to gather feedback to refine and improve the instructional materials. The second part consists of the exploration of the Second Quantum Revolution as a context to introduce some basic concepts of quantum physics. We present the results of an implementation with secondary school students to investigate if and to what extent external representations could play any role to promote students’ understanding and acceptance of quantum physics as a personal reliable description of the world.

Simulatore d’alba come possibile contromisura al social jetlag in adolescenza

L’obiettivo del presente progetto di ricerca era determinare se l’utilizzo non clinico del simulatore d’alba (un dispositivo che emette luce in graduale aumento prima del risveglio), basato su specifiche conoscenze cronobiologiche, potesse ridurre alcune delle conseguenze del social jetlag, in studenti di scuola secondaria di secondo grado. A tal fine, sono stati valutati gli effetti del simulatore d’alba su tono dell’umore (valutato soggettivamente tramite la Global and Vigor Affect Scale-GVA), livelli di attivazione (valutati soggettivamente tramite la GVA), qualità/quantità di sonno (valutate oggettivamente e soggettivamente tramite attigrafia e Mini Sleep Questionnaire-MSQ), architettura del sonno (valutata oggettivamente tramite Zeo®) ed efficienza dei tre network attentivi (alerting, orienting ed executive), valutata oggettivamente tramite l’Attention Network Test (ANT). In totale, hanno preso parte alla ricerca 56 adolescenti (24 femmine e 32 maschi), frequentanti due istituti di scuola secondaria di secondo grado nella città di Cesena, la cui età media era di 17.68 anni (range d’età 15-20 anni). Ad ogni studente è stata richiesta una partecipazione di 5 settimane consecutive ed il disegno di ricerca prevedeva 3 condizioni sperimentali: baseline, simulatore d’alba e controllo. All’MSQ, in seguito all’utilizzo del simulatore d’alba, sono state osservate una minore percezione di sonnolenza diurna, una frequenza inferiore di risvegli notturni ed una riduzione del numero di partecipanti che presentavano una cattiva qualità della veglia. All’ANT, è stato documentato un significativo miglioramento dell’efficienza del network attentivo dell’alerting, successivo all’impiego del simulatore d’alba, dovuto ad una maggiore reattività dei partecipanti in seguito alla comparsa del double cue, che anticipava la presentazione del target (freccia centrale di cui i partecipanti dovevano giudicare la direzione). Tali risultati convergono nell’evidenziare la capacità del simulatore d’alba di esercitare un effetto attivante/stimolante, mostrando dunque come esso possa essere considerato uno strumento potenzialmente utilizzabile quale contromisura al social jetlag in adolescenza.
