Personality differences in individuals of various sexual orientations
Fořt, Jakub ; Havlíček, Jan (advisor) ; Procházka, Ivo (referee)
The previous research identified a range of personality differences between men and women of various sexual orientations. Non-heterosexual individuals systematically show higher gender nonconformity and greater openness to experience than heterosexual individuals. Non-heterosexual men also show higher levels of neuroticism compared to heterosexual men. The main aim of this study is to replicate previous findings regarding personality differences. The study further aims to determine whether some of the observed differences in personality factors might be explained by differences in gender nonconformity among individuals of various sexual orientations. Via an online survey, a short version of the Big Five Inventory (BFI-10) and a number of scales measuring gender nonconformity were administered to men (N = 3,418) and women (N = 4,690). In total, 232 individuals identified as asexual, 1,814 as bisexual, 3,024 as heterosexual, 2,468 as homosexual, and 570 as pansexual. Our results demonstrate higher gender nonconformity among non-heterosexual men and women, higher neuroticism among non-heterosexual men, and greater openness to experience among bisexual men and women compared to heterosexual individuals. Asexual women showed lower levels of extraversion than women of other sexual orientations. Gender...

The role of the nutritional therapist for people living with HIV
Tomanová, Michaela ; Starnovská, Tamara (advisor) ; Procházka, Ivo (referee)
Nutrition is one of the prognostic, predictive and also modifiable risk factors for the development of civilization diseases, which unequivocally cause the highest mortality in our territory. Obesity, metabolic syndrome, cardiovascular disease, hypertension, and type 2 diabetes mellitus have been shown to progress earlier and more progressively among people living with human immunodeficiency virus (PLWH) rather than in the HIV-negative population. Thanks to the modernization of antiretroviral therapy (ART), the incidence of wasting or lipodystrophic syndrome among adherent individuals is very low, if not zero. However, HIV infection together with the ART and unhealthy lifestyle now represent a certain risk of undesirable comorbidities in the form of civilization diseases. The complex topic of nutritional care for PLWH should be part of the professional knowledge of every nutritional therapist. Questionnaire surveys intended for qualified nutritional therapists and educational institutions, which were applied for the first section of the practical part of this thesis, confirmed all formulated hypotheses. The result of this part is the finding of insufficient education and the absence of deeper knowledge in the field of nutrition for PLWH among almost 95 % of the interviewed nutrition therapists,...

Parent's coping mechanisms with the descendant's transsexualism
Gregorová, Pavlína ; Weiss, Petr (advisor) ; Procházka, Ivo (referee)
This thesis deals with parental coping with the transsexualism of their offspring. A questionnaire containing 66 items was created for this purpose. 16 parents of transsexual offspring participated in the research (12 mothers, 4 fathers). Just two offsprings were MtF, the others were FtM. 11 parents were contacted via their transsexual offspring, four parents were addressed at while attending a psychotherapeutic group for parents of transsexual offsprings and one parent filled in the questionnaire placed on the Internet. We found out that the most difficult situation for the parents was the moment their transsexual offsprings announced their transsexualism. A majority of the parents were in the state of shock and a majority also felt sorry. After that, the relation between the parents and their transsexual offspring improved. The parents evaluated the current relation between them and their transsexual offspring as sufficiently good. The person who helped the parents most to cope with the transsexuality of their offspring was his or her spouse, however in most of the cases nobody actually helped the parent. The majority of the parents managed to cope with the transsexuality of their offspring within one month. Data analysis showed that almost all parents, who participated in this research, have already...

Dominance Strategies in Romantic Couples' Interactions
Průšová, Denisa ; Weiss, Petr (advisor) ; Procházka, Ivo (referee) ; Poláčková Šolcová, Iva (referee)
This doctoral thesis combines three major topics of how Romantic Couples verbally and nonverbally Communicate Dominance. We research their behavioral dynamics from Evolutionary and Communication perspectives. Against current psycho-social scientific theories, we do suggest that people that are stereotypically seen as submissive, those using other than direct, active, and aggressive strategies, can achieve their will as well. They simply use behaviors that researchers do not consider as dominant (powerful) behaviors and look for them. We explore the whole spectrum of dominance strategies and their context of where, when, and how they are used. We chose a highly qualitative approach during the data collection and analysis part. We adapted a psychotherapy method for research purposes, our Relationship Drama, to overcome significant limitations that nonverbal and communication research struggles with. Therefore, we could see and further qualitatively analyze real couple's behavior in their real typically appearing conflict interaction. Those are described in the theoretical part of this thesis, in chapter 1. Findings from yet unpublished studies that were presented at conferences and are relevant to specific topics are included as well as one case study illustrating dominance ascription complexity. The...

Nutritional care and eating habits of people living with HIV
Tomanová, Michaela ; Starnovská, Tamara (advisor) ; Procházka, Ivo (referee)
The relationships between nutritional status, infectious diseases, and the immune system suggest that nutrition is an indisputable cofactor in the progression of human immunodeficiency virus (HIV) infection. One of the main complications of HIV infection is multifactorial malnutrition, however, overweight and obesity have become more frequent. A specialized nutritional intervention should be an integral part of routine medical care for people living with HIV. It has been shown that the incidence of wasting syndrome and critical malnutrition among people living with HIV has significantly decreased simultaneously with the side effects of modern antiretroviral drugs. The side effects of modern antiretroviral therapy are much less common than previous generations of drugs. On the other hand, the prevalence of obesity and other chronic diseases associated with it has increased significantly among people living with HIV. The practical part describes and evaluates the monitoring of eating habits of 10 people living with HIV. The aim of this work was to provide a summary of information about proper nutritional care for this population, to evaluate the eating habits of the respondents and to come up with a potentional nutritional intervention and education. Lack of macro and micronutrients and poor eating...

The influence of oral hormonal contraceptive use on female sexuality: the evolutionary perspective
Klapilová, Kateřina ; Weiss, Petr (advisor) ; Procházka, Ivo (referee) ; Blažek, Vladimír (referee)
The proposed thesis is comprised of eleven papers connected by the employment of the evolutionary psychological approach in research on various aspects of human sexuality. The aim of the first monothematic part is to demonstrate the evolutionary-psychological approach to one recent phenomenon in female sexuality - the use of oral contraceptives (OC). OC use has been shown to suppress psychological mechanisms that are considered to be adaptive in the fertile period of the natural menstrual cycle. In particular, OC users' ratings of male stimuli that provide the cues of genetic quality and compatibility are lower in comparison with normally cycling women. Moreover, the increase in sexual desire and in the prevalence of proceptive behaviour observed during mid-cycle in normally cycling women is diminished. However, the impact of this phenomenon on mate-choice and relationship dynamics in an ecological context has not been studied. In the first study, we have analyzed the data of Czech women obtained via representative sampling within the Czech National Survey of Sexual Behavior. Results indicated that normally cycling women had a significantly higher number of one-night stands during the last year in comparison to OC users even when living in a long-term relationship. OC usage was also shown to have...

Sexual and psychological aspects of the lives of male sex workers in Prague
Bar - Johnson, Michael ; Weiss, Petr (advisor) ; Pastor, Zlatko (referee) ; Procházka, Ivo (referee)
Prague, the Czech Republic is a popular sex tourism destination where sex work is decriminalized and young men offer sexual services at low prices relative to countries in Western Europe. This quantitative survey aims to identify some of the demographic and personality characteristic of these young men in the sex industry. Internet escorts (N=20) and sex workers in bars and clubs (N=20) completed the survey anonymously in the Spring of 2011. The results show that while sex workers in clubs often have troubled pasts and were forced into sex work in order to survive, the larger groups of sex workers in Prague is made up of internet escorts who have backgrounds which are not atypical for the average Czech youth. Personality test results however revealed both groups to have strong asocial characteristics in comparison to other Czech youth. The results of the measures of mental health (anxiety and depression) indicate that simply working as a male sex worker per se has little relationship to the healthy psychological functioning of these young men, but only in the case where they identify as homosexual. Identifying as a heterosexual is associated with a higher level of substance use. Those identifying as bisexual however reported suffering significantly levels of anxiety within the clinical range and...
