Nationwide survey of contraceptive and sexually transmitted infection knowledge,attitudes and skills of university students in Portugal

Sexually transmitted infections and (STIs) unintended pregnancies are contemporary public health concerns. Understanding factors (e.g. knowledge, attitudes and skills) influencing sexual behaviours of university students are critical to develop targeted and tailored risk-reduction interventions for this vulnerable population. Thus, the goals of this study were to describe sexual behaviours and analyze differences between genders for sexual behaviours; to identify whether differences exist between genders and age groups regarding knowledge, attitudes and skills concerning contraceptive methods and STIs, and to evaluate the association of knowledge with attitudes and skills with sexual behaviour among university students in Portugal. The sample included 3278 students. Results show that the majority were sexually active and use condoms and oral contraceptives. In general, university students have high knowledge, positive attitudes and skills about contraception and STIs. Gender analyses indicated that women had greater knowledge, and more favourable attitudes, and higher skills toward contraceptive and STI preventive behaviour College students, in particular, face new challenges in sexual health and would benefit from more comprehensive education aimed at promoting healthy decision-making about family planning and STI prevention.     

Information and attitudes about HIV/AIDS in Portuguese adolescents: state of art and changes in a four year period

The incidence of infection with HIV/AIDS among the heterosexual population has been increasing in young adults. The goal of this research was to deepen knowledge of preventive sexual behavior in Portuguese adolescents, including knowledge and attitudes about HIV/AIDS, and assessing whether they changed from 2002 to 2006. Data were collected through a self-administered questionnaire from the Portuguese sample of the Health Behavior in School-aged Children (HBSC), a collaborative WHO study. The study provides national representative data of 7093 Portuguese adolescents, randomly chosen from those attending 8th and 10th grade of high school. Results showed there was an increase in the age of first sexual intercourse and a decrease in the number of teenagers who reported having had sexual intercourse, also in the level of information regarding HIV/AIDS transmission/prevention and in positive attitudes towards people with HIV/AIDS. In general, adolescents have good knowledge about how to protect themselves from becoming infected. However, comparing to 2002, there was a reduction of knowledge and consequent increase in the doubts regarding HIV/AIDS. Given the incipient state of sex education in 2006, the results cannot be attributed to sex education, but they will be relevant for comparison with the 2010 HBSC results.     

Sport participation,body satisfaction and depressive symptoms in adolescence: a moderated-mediation analysis of gender differences

This research aimed to analyse the partial mediating role of body satisfaction in the relationship between sport participation and depressive symptoms, as well as to examine the moderating role of gender in these associations. A cross-sectional study was conducted with a sample of 1810 adolescents aged 13–18 years old who completed self-report measures regarding sport participation, body satisfaction and depressive symptoms. The results indicated that a higher frequency of sport participation was associated with a lower presence of depressive symptoms, both directly and through greater body satisfaction, although gender differences were found in this partial mediation model. It was detected that sport participation had a greater effect on positive body satisfaction among boys, whereas body dissatisfaction indicated a greater presence of depressive symptoms among girls. The results emphasize the need to implement gender-specific programmes to improve psychological adjustment in adolescents by promoting sport practice and body acceptance.     

Personal trust extends cooperation beyond trustees: A Mexican study

We studied 2 groups of workers from Oaxaca (Mexico) with different levels of income and education to investigate the role that the affective‐based psychological mechanism of personal trust, as evolutionarily acquired, plays on group cooperation. We measured trust levels through some questionnaires and cooperative behaviour through an iterated prisoner's dilemma under different conditions and analysed trust networks of group members. While these groups did not differ in trust levels or cooperation among trustees, they did differ in terms of cooperation with other group members. Such differences are related to dissimilarities in the trust network topology—as a measure of group cohesion. These results suggest that some personal trust networks extend cooperation within a group beyond trustees in a way that complements the role of the reputation for indirect reciprocity.     

Observers’ reactions to workplace incivility in the masculine domain: How does role congruency explain gender bias in future workers?

Based on Role Congruity Theory, we tested the hypothesis of gender bias by examining gender differences in observers’ evaluations of the awareness and acceptability of workplace incivility gender‐dyad interaction. Three hundred and ninety‐six Spanish high school students (55.3% female) read one scenario of overt incivility (publicly humiliates and openly doubts the employee's judgment) or covert (omits and pays little attention) from a leader (female vs. male) toward a subordinate (female vs. male) in engineering. Results indicated gender differences among observers. From the leader actor of incivility, males were more aware and accepted less the incivility when performed by a female leader in a male domain; whereas females were more aware and accepted less incivility than males in all cases. Regarding the subordinate target of incivility, only females were more aware and accepted less incivility, and both males and females were more aware and accepted less covert incivility. Our results reveal practical implications for interventions from a gender perspective.     

Modifying drug-reinforced behavior by altering the economic conditions of the drug and a nondrug reinforcer.

Six rhesus monkeys were trained to self-administer orally delivered phencyclidine (0.25 mg/mL) and saccharin (0.03% wt/vol) under concurrent fixed-ratio 16 schedules. In Condition 1 the fixed-ratio requirement for phencyclidine was changed from 16 to 4, 8, 16, 32, 64, 128 and 16 while the fixed-ratio requirement for saccharin deliveries remained constant at 16. In Condition 2 the fixed-ratio value for saccharin was systematically altered while the fixed-ratio requirement for phencyclidine remained at 16, and in Condition 3 the fixed-ratio requirements for both phencyclidine and saccharin were altered simultaneously. Water was then substituted for saccharin, and the series of fixed-ratio manipulations was replicated. The phencyclidine concentration was reduced to 0.125 mg/mL and Conditions 1 and 3 were repeated. When the fixed-ratio requirement for phencyclidine was increased and the fixed-ratio requirement for saccharin or water remained fixed at 16, phencyclidine deliveries decreased when saccharin (vs. water) was concurrently available. The magnitude of the decrease ranged from 20% to 90% (of the concurrent water condition) as the fixed-ratio requirement for phencyclidine increased from 4 to 128. When the fixed-ratio requirement for phencyclidine remained at 16 and the fixed-ratio requirements for concurrent saccharin or water varied between 4 and 128, phencyclidine deliveries decreased by 30% to 40% due to the concurrent availability of saccharin (vs. water). This decrease occurred only at the three lowest fixed-ratio values when saccharin intake was relatively high. When the fixed-ratio requirements for both phencyclidine and concurrent saccharin or water were varied simultaneously, phencyclidine deliveries were reduced from 20% to 45% when saccharin (vs. water) was concurrently present. There was little effect of reducing the phencyclidine concentration when the data were analyzed in terms of unit price (responses per milligram). Thus, changes in the fixed-ratio requirement or drug concentration were functionally similar, and unit price of phencyclidine was the variable that was influenced by the presence of concurrent saccharin. These data indicate that drug-reinforced behavior is substantially reduced when the environment is enriched with an alternative nondrug reinforcer. The economic context in which these substances are presented is an important determinant of drug-reinforced behavior.     

Mathematical background and attitudes toward statistics in a sample of Spanish college students

To examine the relation of mathematical background and initial attitudes toward statistics of Spanish college students in social sciences the Survey of Attitudes Toward Statistics was given to 827 students. Multivariate analyses tested the effects of two indicators of mathematical background (amount of exposure and achievement in previous courses) on the four subscales. Analysis suggested grades in previous courses are more related to initial attitudes toward statistics than the number of mathematics courses taken. Mathematical background was related with students' affective responses to statistics but not with their valuing of statistics. Implications of possible research are discussed.     

The Interplay Among Levels of Personality: The Mediator Effect of Personal Projects Between the Big Five and Subjective Well-Being

Comprehensive models of personality aspire to integrate the several aspects related to the study of personality in a coherent whole. One of the great research challenges in this field is to understand if and how different levels of personality analysis interrelate to promote human well-being. The aim of the present study is to explore the mediator effect of personal projects’ efficacy on the relationship between Big Five and subjective well-being (SWB) components. We conducted a cross-sectional study in which a battery of self-report questionnaires was used to assess personality and SWB in 396 teachers. Path analysis results indicated that personal projects’ efficacy fully mediated the effects of openness to experience, agreeableness and conscientiousness on life satisfaction and on negative affect. The effects of neuroticism, openness to experience, agreeableness and conscientiousness on positive affect were direct but also indirect, partially mediated by personal projects’ efficacy. Neuroticism had a direct and an indirect effect through a decreased personal projects’ efficacy on the three components of SWB. Extraversion only directly predicted increased positive affect. These findings corroborate the conceptualization that these two types of personality analysis units (Big Five and personal projects) have their own direct, unique and irreducible effect on life satisfaction, positive affect and negative affect. However, their impact on SWB components seems to be also explained through their effect upon personal projects’ efficacy.     

A temporal common ground for learning: The moderating effect of shared mental models on the relation between team learning behaviours and performance improvement

In this longitudinal study, we integrated a team process and a learning curve perspective on team learning and empirically analysed whether team learning processes lead to performance improvement. In addition, we tested whether this relation is moderated by the similarity of team members’ task, team, and temporal mental models. We tested our model on a sample of 67 teams (314 individuals) competing in a management simulation over five consecutive time periods, using random coefficient modelling (RCM). Our findings suggest that team learning behaviours do not have a direct effect on the team learning curve, but temporal and task mental models are crucial for the translation of team learning behaviours into performance improvement. We found that when teams have similar task and temporal mental models, engaging in team learning processes is beneficial, whereas, when teams have dissimilar task and temporal mental models, it is detrimental to performance improvement. We did not find a significant effect for the moderating role of team mental model similarity. Our study emphasizes the importance of integrating different perspectives on team learning and provides support for the role of team cognition as a catalyst for team learning.     

Effect of Religious Day on Prosocial Behavior: A Field Study

It has previously been suggested that prosociality is correlated with the degree of religiousness. However, experimental and meta-analytical studies cast doubt on the existence of such a relationship. Due to the controversy over the link between religiousness and prosocial behavior, and the existence of only a small number of ecological experiments focusing on this relationship, we tested the effect of a religious salient day, a previously uninvestigated effect, on prosocial behavior. Specifically, across two experiments (N = 405) and in an ecological setting in Portugal, we tested whether prosocial behavior would increase on a religious salient day compared to a non-religious regular day. We found a gender-related effect: Women, on a religious day, were more inclined to agree to a prosocial behavior than on a non-religious day, whereas men did not change their behavior. We discuss such a difference in behavior, as well as the implications of our studies.
