RESUMO

PURPOSE: Gender stereotypes refer to consensual or cultural shared beliefs about the attributes of men and women, influencing society behaviors, interpersonal relationships, education, and workplace. The literature has shown the existence of gender stereotypes on career choices, internalization of roles, and school and social experiences and demonstrates the impact of demographic factors on stereotypes. However, all the studies conducted in Italy available in scientific literature analyzed small sample sizes within specific schools of university settings, with a limited age range. METHODS: To assess the current state of gender stereotypes in Italy, we conducted an online survey from October 2022 to January 2023 on the general population residing in Italy. The questionnaire comprised sociodemographic factors and questions about gender stereotypes, investigating six fields: games, jobs, personality traits, home and family activities, sports, and moral judgments. RESULTS: The study involved 1854 participants, mostly women (70.1%) with an undergraduate or postgraduate degree (57.5%). The statistical and descriptive analyses revealed that gender stereotypes influenced respondents' beliefs, with statistically significant effects observed in most questions when stratifying by age, gender, and degree. Principal component analysis was performed to assess latent variables in different fields, revealing significant main stereotypes in each category. No statistically significant differences between men and women were found for the fields home and family activities, games, and moral judgments, confirming that stereotypes affect both men and women in the same way. CONCLUSIONS: Our results show the persistence of gender stereotypes in any fields investigated, although our cohort is predominantly composed of high educational level women living in the North of Italy. This demonstrates that the long-standing gender stereotypes are prevalent, pernicious, and, unfortunately, internalized at times even by successful women pushbacking and sabotaging them unconsciously.

RESUMO

BACKGROUND: Older people are increasing in the world leading to the fact that many nursing students will work in geriatric care setting. It was also reported the lack of knowledge and interest in working with older people by many nursing students. Therefore, the aim of the study is to explore the attitudes, wills, and intentions for the care of older people from nursing students. METHODS: A sample of 383 students (mean age between 17 and 24; females: 76.2%) was divided according to the year. A questionnaire and three scales investigating the attitude for working with older persons (Kogan, Aday-Campbell, Nolan scales) were administered. Simple correlations across the three scales and the comparisons in means by year of graduation were reported. RESULTS: Of the 383 students, 69.7% would take care of an older person, with the previous experience with older patients being the most important determinant in positive attitude of students in working with older people. The Kogan scale revealed a relatively positive attitude towards older people of the students involved; the Aday's scale a reasonable willingness to take care of the older people; the Nolan scale a fair intention. Aday's scale significantly correlated with Nolan's scale and with Kogan's scale as well as the Nolan scale correlated with the Kogan scale. CONCLUSION: Our study suggests that the quality of care provided to older people is related to the attitudes of health professionals indicating that nursing educators should adopt effective strategies to increase and promote students' positive attitudes to older people.

RESUMO

The present study uses agent-based modeling (ABM) to examine the effectiveness of a nudge policy for improving recycling behavior. In our simulation, agents' recycling behavior is computed by components of the Theory of Planned Behaviour (i.e., attitudes, perceived behavioral control, social norms) and influenced by other agents as well as their surrounding (i.e., amount of waste in the area). The simulation, based on real data from a Taiwan community district, confirms realistic recycling trends and demonstrates the usefulness and reliability of ABM as a method to examine the effectiveness of waste management policies. An additional step in our simulation was to manipulate the amount of waste in the community to test the effect of a nudge policy based on social norms. Results showed that the policy increases recycling activity, but predominantly in low waste scenarios. This suggests that nudges, in the form of norm-based policies, can be an effective solution to enhancing people's recycling behavior under specific circumstances.

RESUMO

AIMS: The study aims are (a) to test a model developed to estimate the impact of work engagement on work ability as it is perceived by nurses; (b) to test the parameters between work ability and job satisfaction and between job satisfaction and turnover intention. DESIGN: Cross-sectional. METHODS: This study involved 1,024 nurses from January - May 2018. The response rate was 70.7%. The Work Ability Index and the Utrecht Work Engagement Scale were used. Path analysis was performed, both in the whole sample and in age categories (<45yy-≥45yy). Model's parameters and fit indexes were estimated. RESULTS: The comprehensive model was validated through the multi-group approach. Fit indexes were adequate in the general model and in the multi-group testing. Parameters confirmed the association between work engagement and work ability and between work ability and job satisfaction and turnover intention. Parameters highlighted different age-dependent patterns. CONCLUSION: This study states the contribution of work engagement to enhance work ability in nursing profession. Findings contribute in understanding motivational dynamics in nurses and they suggest the use of tailored strategies for different age categories. Further research could address the model to deepen generational patterns in work engagement, work ability, and organizational outcomes. IMPACT: The study highlights how to address nursing management to improve nurses' motivation and work ability and to improve organizational outcomes. Main findings point out different age-dependent patterns to tailor managerial strategies. Healthcare organizations have new elements to design human resources management and to improve job satisfaction and nurses' retention.

RESUMO

Most relevant theories of prosocial behavior aim at exploring and understanding helping motivations from an evolutionary perspective. This article summarizes findings from research on prosocial behavior from both a socio-economic and psychological perspective. Building on literature exploring the basic processes and determinant variables of helping, we propose a stochastic and dynamic model to simulate prosocial behaviors over time and recreate evolutionary processes of helping behaviors. Such a mathematical model formalizes a procedure for dynamic simulations, including agent-based modeling, which implies non-linear dynamics of prosocial processes underlying helping motivations. Practical implications for organizations and societies are addressed.

RESUMO

It is likely that computer simulations will assume a greater role in the next future to investigate and understand reality (Rand & Rust, 2011). Particularly, agent-based models (ABMs) represent a method of investigation of social phenomena that blend the knowledge of social sciences with the advantages of virtual simulations. Within this context, the development of algorithms able to recreate the reasoning engine of autonomous virtual agents represents one of the most fragile aspects and it is indeed crucial to establish such models on well-supported psychological theoretical frameworks. For this reason, the present work discusses the application case of the theory of planned behavior (TPB; Ajzen, 1991) in the context of agent-based modeling: It is argued that this framework might be helpful more than others to develop a valid representation of human behavior in computer simulations. Accordingly, the current contribution considers issues related with the application of the model proposed by the TPB inside computer simulations and suggests potential solutions with the hope to contribute to shorten the distance between the fields of psychology and computer science.

RESUMO

During the last decade, the purchase of organic food within a sustainable consumption context has gained momentum. Consequently, the amount of research in the field has increased, leading in some cases to discrepancies regarding both methods and results. The present review examines those works that applied the theory of planned behavior (TPB; Ajzen, 1991) as a theoretical framework in order to understand and predict consumers' motivation to buy organic food. A meta-analysis has been conducted to assess the strength of the relationships between attitude, subjective norms, perceived behavioral control, and intention, as well as between intention and behavior. Results confirm the major role played by individual attitude in shaping buying intention, followed by subjective norms and perceived behavioral control. Intention-behavior shows a large effect size, few studies however explicitly reported such an association. Furthermore, starting from a pooled correlation matrix, a meta-analytic structural equation model has been applied to jointly evaluate the strength of the relationships among the factors of the original model. Results suggest the robustness of the TPB model. In addition, mediation analysis indicates a potential direct effect from subjective norms to individual attitude in the present context. Finally, some issues regarding methodological aspects of the application of the TPB within the context of organic food are discussed for further research developments.

RESUMO

Mobile phone use while driving (MPUWD) is an increasingly common form of distracted driving. Given its widespread prevalence, it is important for researchers to identify factors that may predict who is more likely to engage in this risky behavior. The current study investigates associations between MPUWD risk behaviors, domain-specific risk perceptions, and broad personality dimensions. An Italian community sample (n = 804) completed a survey regarding MPUWD risk perceptions and engagement in MPUWD, in addition to the HEXACO-PI-R, a broad six-factor personality inventory (honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, openness to experience), and the DOSPERT, a six-factor domain-specific self-report risk-taking measure (health/safety, recreational, social, ethical, gambling, and investment). With respect to domain-specific risk taking, greater frequency of SMS use while driving most strongly was associated with greater risk taking for the health/safety, gambling, and ethical risk domains. Further, greater honesty-humility and conscientiousness, two traits related to cognitive control and risk behaviors, and to a lesser extent openness to experience, were associated with less frequent MPUWD, and positively associated with MPUWD risk perceptions. With growing public safety concern surrounding MPUWD, understanding associated personality factors is not only important for identifying psychological mechanisms underlying risk behavior, but also for more effective prevention and intervention programs.

RESUMO

OBJECTIVES: Electroconvulsive therapy (ECT) is the most effective therapy for patients with treatment-resistant depression; however, some patients do not respond or relapse in a short time. Electroconvulsive therapy stimulus parameters may be related to the outcome. We carried out a retrospective study review to investigate various ECT parameters in relation to the outcome, clinical variables, and pharmacological treatments. Our aim was to understand which factors could be considered putative seizure quality markers and which are relevant to clinical practice. METHODS: Two physicians evaluated the seizure length, the postictal suppression index, the wave amplitude, tachycardia, and hemispheric brain wave synchronicity in a double-blind manner for 45 treatment-resistant depression patients receiving ECT. RESULTS: The analysis showed a significant association between the outcome and the ECT seizure quality measured by the parameters (P = 9.9 × 10). Among patients with poor-quality seizures, 61.5% relapsed after approximately 1 month from the last ECT session. Particularly, there was an association between higher symptomatology decrease and higher quality of hemispheric brain wave synchronicity (P = 5.0 × 10), as well as a higher wave amplitude (P = 0.01). CONCLUSIONS: Our results confirm that ECT seizure quality was strongly correlated with the decrease of depressive symptomatology.

RESUMO

AIM: The aim of this study was to determine which organisational socialisation contents affect turnover intention in newcomer nurses within their first 2 years of employment. BACKGROUND: Strategies to decrease turnover are a priority for improving organisational stability, reducing costs and enhancing effective nursing care. MATERIALS AND METHODS: A cross-sectional design was employed, and standardised scales were used. The sample was divided into three groups: 0-6, 7-12 and 13-24 months of employment. Regression analyses were performed. RESULTS: A total of 156 Italian nurses participated in this study. In the 0-6 months group (model 1), the main factors that decreased turnover intention were competence acquisition (ß = -0.42, P < 0.01) and comprehension of organisational rules (ß = -0.38, P < 0.01). In the 7-12 months group (model 2), workgroup integration was relevant (ß = -0.33, P = 0.02) and in the second year (model 3), the main factor was opportunities for professional development (ß = -0.30, P = 0.05). CONCLUSIONS: Newcomer nurses were sensitive to different organisational socialisation contents over time. This result supports planning different on-boarding strategies to enhance organisational socialisation success and to improve nurse retention. IMPLICATIONS FOR NURSING MANAGEMENT: Useful strategies to improve retention include enhancing task mastery and workgroup integration at the ward level and a professional development plan at the organisational level.

RESUMO

INTRODUCTION: In the first years of nursing profession, new-graduate nurses' turnover intention is a relevant issue due to both the tangible and intangible costs it generates to health care organizations, such as selection and recruitment costs, ward team burden in the onboarding process and the possibility to enhance ward team stability in order to provide an effective and safe nusing care. Organizational socialization is the main factor involved in these dynamics of turnover intention in the first years of nursing profession. AIMS: This study aims to identify the main factors involved in the organizational socialization process to reduce turnover intention in the first 3 years of nursing profession. METHODS: 101 new-graduate nurses have been enrolled within the first three years of nursing profession. They have been stratified looking at tenure and years in nursing. Organizational Socialization Inventory scale has been used to assess the onboarding process and 4 items to assess turnover intention. RESULTS: Turnover intention is of 23% in the first year in nursing, and it's over the 26% starting from the second year. The onboarding process explains over the 26% of the variance in turnover intention, and over the 36% in the sub-sample with a stable tenure. Unstable tenured nurses prefer to acquire those competences useful to perform their work, while stable tenure nurses aim to search for professional growth opportunities and integration in the ward-team, in order to reduce turnover intention. CONCLUSION: Turnover intention is relevant in the first three years of nursing profession. According to the different tenure, different strategies are necessary to plan an effective onboarding process and enhance nursing retention.

RESUMO

BACKGROUND: Anxiety disorders exhibit remarkably high rates of comorbidity with major depressive disorder (MDD). Mood and anxiety disorders are considered stress-related diseases. Genetic variations in the co-chaperone FK506-binding protein 51, FKBP5, which modulates the function of glucocorticoid receptors, have been associated with an increased risk for the development of posttraumatic stress disorder, but data regarding its role in MDD are controversial. The aims of this study were to clarify the role of the FKBP5 gene in depression and anxiety disorders through a case-control study and an association study with personality traits using the Temperament and Character Inventory (TCI) in healthy subjects. METHODS: Six hundred fifty-seven MDD patients, with or without an anxiety disorder in comorbidity, and 462 healthy volunteers were enrolled in the study. Two hundred fifty-six controls agreed to fill out the TCI. RESULTS: The results showed that the T allele of rs1360780 was more frequent among the patients affected by MDD with a comorbidity of anxiety disorders, compared to those without (P < .001). Among the controls, we found that the T allele more often exhibited personality traits associated with an increased vulnerability to anxiety. CONCLUSIONS: These results support the hypothesis that allelic variants of FKBP5 are a risk factor for anxiety disorders. The identification of genetic variants involved in anxiety may have implications for the optimization of therapeutic interventions.

RESUMO

Social media platforms offer significant growth opportunities for enterprises, particularly microenterprises, due to the chance to establish direct contact with customers. Drawing on the Technology-Acceptance Model (TAM), in the present study, we investigate the psychological reasons that lead microentrepreneurs to use Social Networking Sites (SNSs) for their business. In doing so, we also extend TAM by taking into account entrepreneurs' personalities (e.g., extraversion and openness to experience) and their perceived risk. We collected data by examining 247 microentrepreneurs engaged in the production of handmade objects. Our results confirm that of all the TAM behavioral antecedents tested, perceived usefulness and attitude toward SNSs' usage for business proved to be the best predictors of the intention to use SNSs for business activity. The results also indicate that extraversion, openness to experience, and perceived risk, as external factors, significantly affect the TAM constructs. We discuss implications and suggestions for future research.

RESUMO

AIMS AND OBJECTIVES: To determine whether a specific training course will enhance empathic skills in student nurses during a 3-year degree course. The study considers levels of empathy in student nurses and assesses whether these can be increased. BACKGROUND: Empathy is accepted as a critical component of supportive relationships. Many scholars have argued that empathy provides health professionals with the capacity to improve the health of patients, so it should ideally be taught to make health professionals more responsive to patient needs. DESIGN: Cohort longitudinal study. METHODS: Data were collected using the Italian version of the Balanced Emotional Empathy Scale (BEES). The study was designed to guarantee repeated measurements of levels of emotional empathy in the pre- and postintervention phases. This allowed us to evaluate the development and improvement of empathy and to measure the effects of extra training on the students' empathy skills. Two groups took part in the study: the Intervention and the Control Groups. Students in the Intervention Group attended additional seminars and laboratories in small groups with tutors to learn and develop communicative and empathic abilities. RESULTS: One hundred and three participants (76% women) completed the study. Data showed that the training course was effective, especially for women: BEES scores 31.60 at pre-intervention phase and 42.91 at the end of the academic course. Results regarding men were less clear, and the study discusses these unexpected, anomalous findings. CONCLUSION: According to literature, men and women have different empathic traits, and we found that they show disparate empathic tendencies. More women than men took advantage of the training course. In any case, our data show that specific training courses are effective. RELEVANCE TO CLINICAL PRACTICE: As our study shows, empathy is a skill that may be taught. So it would be advisable to introduce these into the traditional nursing curriculum.

RESUMO

Vocational Education and Training (VET) programs are fuelled by technical and practical educational modules. The teaching staff adopts both traditional and innovative pedagogical frameworks to increase the generalization and maintenance of practical skills. At the same time, VET teachers and trainers have a few occasions to promote and include disciplines and educational programs for enhancing students' soft skills, e.g., critical thinking skills (CT) and media literacy (ML). Following the European VET framework and literature of the field, CT and ML represent a social challenge that requires even more efforts by academics, practitioners, and policymakers. Thisstudy situates into this context with the aim of introducing a novel educational approach for supporting the teaching staff in the promotion of students' CT and ML. This educational approach has been realized by the team of researchers and trainers of the NERDVET project, an Erasmus+ KA3 project devoted to the promotion of new tools and policies for enhancing CT and ML in VET. To pursue this aim, the team has employed the self-nudging model which regards the individuals' set of cognitive and behavioral strategies that individuals can develop to target a specific objective. By framing pedagogical strategies into this perspective, the team realized an initial approach for educational activities and teaching strategies to promote students' CT and ML.

RESUMO

Consisting evidence in animal models has suggested that alterations in brain-derived neurotrophic factor (BDNF) brain expression and release are involved in the pathogenesis of mental illnesses, such as, mood, anxiety, and eating disorders. This hypothesis is supported by data emerging from biochemical studies on serum BDNF levels and genetic studies on the functional polymorphism Val66Met in the BDNF gene in patients and control subjects. Anxiety-related personality traits are associated with several mental disorders. However, they are also measurable in non-affected subjects and, so, may represent a useful "endophenotype" to study the biological correlation of the vulnerability factors in the general population. In this study, we analyzed putative correlations in subjects unaffected by mental disorders between personality traits, serum BDNF levels (N = 107), and the BDNF Val66Met genotype (N = 217). Furthermore, we tested the possible interactions between these variables. A significant correlation has been observed between high scores of harm avoidance (HA) measured by the temperament and character inventory (TCI), and low BDNF serum concentration (r = -0.253, P = 0.009). In addition, an association has been evidenced between low BDNF levels in serum and the BDNF Val/Val genotype (P = 0.021). By analyzing putative concomitant effects of different variables on HA scores in a regression model, we observed a significant correlation only with BDNF serum concentrations (P = 0.022). The study results suggest that a decrease in serum BDNF concentrations may represent a biochemical marker associated with anxiety personality traits also retrievable in the general population.

RESUMO

BACKGROUND: A genetic liability for anxiety-related personality traits in healthy subjects has been associated with the functional serotonin transporter promoter polymorphism (5-HTTLPR), although the data are somewhat conflicting. Moreover, only one study has investigated the functional significance of the 5-HTTLPR/rs25531 haplotypes in relation to anxiety traits in healthy subjects. We tested whether the 5-HTTLPR polymorphism and the 5-HTTLPR/rs25531 haplotypes are linked to Harm Avoidance (HA) using an association study (STUDY I) and a meta-analytic approach (STUDY II). METHODS: STUDY I: A total of 287 unrelated Italian volunteers were screened for DSM-IV Axis I disorders and genotyped for the 5-HTTLPR and rs25531 (A/G) polymorphisms. Different functional haplotype combinations were also analyzed. STUDY II: A total of 44 studies were chosen for a meta-analysis of the putative association between 5-HTTLPR and anxiety-related personality traits. RESULTS: STUDY I: In the whole sample of 287 volunteers, we found that the SS genotype and S'S' haplotypes were associated with higher scores on HA. However, because the screening assessed by Mini-International Neuropsychiatric Interview (M.I.N.I.) showed the presence of 55 volunteers affected by depression or anxiety disorders, we analyzed the two groups ("disordered" and "healthy") separately. The data obtained did indeed confirm that in the "healthy" group, the significant effects of the SS genotype and S'S' haplotypes were lost, but they remained in the "disordered" group. STUDY II: The results of the 5-HTTLPR meta-analysis with anxiety-related traits in the whole sample confirmed the association of the SS genotype with higher anxiety-related traits scores in Caucasoids; however, when we analyzed only those studies that used structured psychiatric screening, no association was found. CONCLUSIONS: This study demonstrates the relevance to perform analyses on personality traits only in DSM-IV axis I disorder-free subjects. Furthermore, we did not find an association between functional serotonin transporter gene polymorphisms and anxiety traits in healthy subjects screened through a structured psychiatric interview.

RESUMO

Authors have paid considerable attention to how to define the meaningful work construct. This has led to providing comprehensive definitions in the light of different theoretical frameworks that reflect a degree of contestation within the field. Several of them have proposed definitions linked to the individuals' pervasive sense of the value of their work. Others have offered descriptions centered on their temporal, episodic nature and emphasizing the individual's occasional work experience. These definitions reflected a potential temporal condition as well as the variety of time perspectives underpinning the authors' conceptualizations of the construct. This paper conducted a broad literature review to analyze works that have adopted a temporal framework or supported a time-based definition of the construct. The analysis indicates two different conceptualizations of the construct: as a permanent/steady mindset and as a changeable/episodic experience. As a reflective paper, the present contribution develops an overall framework for views and theories on meaningful work. It reports a critical review on the matter to elevate understanding of meaningful work for further research and applied implications in work and organizational studies.
