Kutatásunk célja az SPSI—A (Social Problem Solving Inventory—Adolescent, Frauenknecht és Black, 2010) adaptálása volt 12 és 16 évesek körében (N=540). A kérdőív konvergens és diszkriminatív validitásának vizsgálatához az SPSI—R-t (Social Problem Solving Inventory—Revised, D’Zurilla és mtsai, 2002), a Davis által kidolgozott empátiakérdőívet (Interpersonal Reactivity Index, 1980), valamint a Spielberger- féle vonás - és állapotszorongást mérő kérdőívet (State-Trait Anxiety Inventory for Children, Spielberger és mtsai, 1973) használtuk. Az eredeti kérdőív 10 faktoros, 64 kijelentésből áll. A feltáró és a megerősítő faktorelemzés eredményei alapján a magyar változat — SPSI—A(H) – 54 tételt tartalmaz, melyek 11 faktorba csoportosulnak (az eredeti Gondolatok faktor kijelentései elkülönülnek a Pozitív gondolatok és a Negatív gondolatok faktorba). A kérdőív mind a 12, mind a 16 évesek mintáján jó megbízhatósággal (a Cronbach-α sorrendben 0,81 és 0,83) mér. Az eredmények alapján az SPSI—A(H)-t alkalmasnak tartjuk a problémamegoldással kapcsolatos automatikus gondolatok, a problémamegoldáshoz való érzelmi, gondolati viszonyulás, az elkerülés, a probléma meghatározása, a célmeghatározás, az alternatív megoldási módok keresése, a következmények végiggondolása, illetve a nem megfelelő megoldás esetében a gondolatok, teendők újraszervezése és az utólagos kiértékelés mérésére.

BackgroundEmpathy is a key health care concept and refers to care that incorporates understanding of patient perspective’s, shared decision making, and consideration of the broader context in which illness is experience. Evidence suggests experiences of doctor empathy correlate with improved health outcomes and patient satisfaction. It has also been linked to job satisfaction, and mental wellbeing for doctors. To date, there is a paucity of evidence on empathy levels among medical students. This is critical to understand given that it is a key point at which perceptions and practices of empathy in the longer term might be formed.AimTo quantify the level of empathy among UK undergraduate medical studentsMethodAn anonymised cross-sectional online survey was distributed to medical students across three universities. The previously validated Davis’s Interpersonal Reactivity Index was used to quantify empathy. The survey also collected information on age, sex, ethnicity, year of medical school training and included a free-text box for ‘any other comments’.ResultsData analysis is currently underway with high response rates. Mean empathy scores by age, sex, year of study and ethnic group are presented. A correlation analysis will examine associations between age and year of study, and mean empathy sores.ConclusionThese data will help to provide a better understanding of empathy levels to inform the provision of future empathy training and medical school curriculum design. Given previous evidence linking experiences of empathy to better health outcomes, the findings may also be significant to future patient care

Background: With the gradual decrease of fossil energy, the development of alternatives to fossil energy has attracted more and more attention. Biodiesel is considered to be the most potent alternative to fossil energy, mainly due to its green, renewable and biodegradable advantages. The stable, efficient and reusable catalysts are undoubtedly the most critical in the preparation of biodiesel. Among them, nanoporous carbon-based acidic materials are very important biodiesel catalysts. Objective: The latest advances of acidic nanoporous carbon catalysts in biodiesel production was reviewed. Methods: Biodiesel is mainly synthesized by esterification and transesterification. Due to the important role of nanoporous carbon-based acidic materials in the catalytic preparation of biodiesel, we focused on the synthesis, physical and chemical properties, catalytic performance and reusability. Results: Acidic catalytic materials have a good catalytic performance for high acid value feedstocks. However, the preparation of biodiesel with acid catalyst requires relatively strict reaction conditions. The application of nanoporous acidic carbon-based materials, due to the support of carbon-based framework, makes the catalyst have good stability and unique pore structure, accelerates the reaction mass transfer speed and accelerates the reaction. Conclusion: Nanoporous carbon-based acidic catalysts have the advantages of suitable pore structure, high active sites, and high stability. In order to make these catalytic processes more efficient, environmentally friendly and low cost, it is an important research direction for the future biodiesel catalysts to develop new catalytic materials with high specific surface area, suitable pore size, high acid density, and excellent performance.

Empathy refers to the capacity to experience emotions similar to those observed or imagined in another person, with the full knowledge that the other person is the source of these emotions. Awareness of one's own emotional states is a prerequisite for self-other differentiation to develop. This study investigated gender differences in empathy during adolescence and tested whether emotional self-awareness explained these differences. Two-hundred-eleven adolescents (108 girls and 103 boys) between 14 and 19 years completed the Interpersonal Reactivity Index (IRI) and the Toronto Alexithymia Scale (TAS-20) to assess empathy and emotional self-awareness, respectively. Overall, girls obtained higher scores than boys on IRI subscales like emotional concern, personal distress, and fantasy. Regarding emotional self-awareness, we found gender differences in TAS-20 scores, with girls reporting greater difficulty identifying feelings and less externally oriented thinking than boys. Difficulty identifying feelings explained the greatest personal distress experienced by girls. Lower externally oriented thinking accounted for girls’ greater emotional concern and fantasy. These findings offer an insight into the role of emotional self-awareness–which is essential for self-other differentiation–as an account for gender differences in empathic abilities during adolescence. In girls, difficulty identifying feelings can impair the ability to differentiate between ones’ and others’ emotions, leading them to experience self-focused and aversive responses when confronted with others’ suffering. Conversely, in boys, externally oriented thinking can mitigate personal distress when faced with others’ discomfort.
