There are no statistically significant differences in personality traits between people who claimed that they would and those that would not be willing to become sperm donors. It is possible that some other factors (e.g. cultural values) influence the decision to become sperm donor, but personality traits play an important role in making decisions regarding sperm donation process, possible receivers of donation and relations between the donor and his biological offspring.

The aim of this study was to validate Holland's hexagonal and Tracey's spherical model of vocational interests in young adults in Serbia and Bulgaria. To this end, 1250 participants, 560 from Serbia and 690 from Bulgaria, filled in Serbian and Bulgarian versions of the Personal Globe Inventory (PGI, Tracey, 2002). Hubert and Arabie's randomization test of hypothetical orders, multidimensional scaling with fixed coordinates, Myors test and exploratory factor analysis were used. The results showed that the hexagonal and spherical models well explained the structure of vocational interests in both samples. The level of fit of the hexagonal model to the data obtained by using the PGI was generally higher than those established in the studies that used other Holland-based instruments. Furthermore, the levels of fit of both hexagonal and spherical model were in the same range like those obtained in previous studies in other countries. The results also pointed out a remarkable similarity in the structure of vocational interests in the Bulgarian and Serbian samples.

Trauma can be described as an injury that leaves permanent consequences, latent traces that can be activated in periods of crisis (Krstić, 2009). In the second part of the 20 th century, the term trauma started being used ever more outside the medical and psychiatric context and entering the domain of social sciences (Sztompka, 2009). In the scope of this, one way the concept of trauma is used is in confronting negative and dysfunctional consequences that social change can leave in its wake. Various authors have studied social and psychological consequences of social changes on individuals and society. In this way, they opened the road to recognizing a new meaning of trauma, which they titled cultural or social trauma. It is known that the theory of emotional attachment states that in crisis or traumatic situations, members of a family group feel insecure, that risks in the environment can lead to lowered responsiveness of the parents, but it is less widely known if unresolved traumatic experiences of parents can be transferred to children and their later emotional attachment patterns. There is particularly little knowledge on whether significant social changes leave consequences on emotional lives of individuals and the emotional lives of their children. In this paper, we try to make a brief review of the literature on the topic, and summarize the theoretical and partly empirical knowledge in the area that exists so far.

The goal of the current study was to examine psychometric properties of the Serbian version of the Multidimensional Jealousy Scale (MJS, Pfeiffer & Wong, 1989). For this purpose, 500 participants, aged 18?40, were asked to complete this version of MJS. In order to examine external validity of MJS, participants were asked to complete The Rosenberg?s self-esteem scale, The Big Five Inventory and the Love Attitudes Scale. Confirmatory factor analysis supported the three-factor structure of the instrument, but required the addition of a number of error covariance arguments to achieve fit. Another model was tested, after which acceptable fit levels were achieved with smaller number of error covariance arguments in the model. Internal consistency of subscales was high. Correlations with neuroticism, self-esteem and mania love styles are consistent with the theoretical expectations and previous results, suggesting good external validity of the instrument.

The goal of the current paper was to explore the construct validity of the spherical and the hexagonal models of vocational interests by exploring the extent to which these models fit the data obtained on samples of Macedonian and Croatian university students. Croatian and Macedonian versions of the Personal Globe Inventory (PGI) were administered to a sample of 1367 student of various faculties in Croatia and Macedonia (737 participants from the Republic of Macedonia and 630 from Croatia). Results showed that the spherical and hexagonal models fit the data better than chance, and that these models explain substantial proportions of variance of vocational interest measures. Exploration of the factor structure of the obtained measures of vocational interest on the studied samples showed that the obtained structure generally corresponds to theoretical propositions. The obtained dimensions correspond to the latent space defined by Prediger’s dimensions and the dimensions of Prestige of the spherical model.
