Validization of diagnostic methods in PTSD
Vágnerová, Anna ; Preiss, Marek (advisor) ; Heider, David (referee)
With this work, I became involved in an ongoing project of tool validation for measuring psychological trauma within the activities of the National Institute of Mental Health - Validation of tools for measuring psychological trauma. The aim of this thesis was to collect data from a clinical population with posttraumatic stress disorder (PTSD) and compare it with the results of diagnostic methods in the general population (N=303). The research clinical sample consisted of 31 respondents who, based on diagnostic criteria for PTSD diagnosis according to DSM-5, were divided into two research groups - with a probable PTSD diagnosis (N=17) and without a probable PTSD diagnosis (N=14). In this work, the results of three research groups were compared using the PTSD Checklist 5 method, which assesses the level of traumatization, and the Life Events Checklist-5 method, which examines the frequency of experienced traumatic events. At the same time, measurement of depressive and anxious symptoms of all participants was conducted to assess convergent validity. The results of statistical analysis showed that the PCL-5 method proved to be valid. The group with a probable PTSD diagnosis achieved statistically significantly higher values than the general population group, even in the results of methods measuring...

Magical Thinking Test
Kadrnožková, Lucie ; Bahbouh, Radvan (advisor) ; Šípek, Jiří (referee)
This M.A. thesis deals with the topic of magical thinking in the adult population. The theoretical section of the thesis summarizes the existing findings in regard to the theory and research of magical thinking. The empirical section is dedicated to the development and subsequent validation of the new testing method devised to measure inclinations to magical thinking. Proving the method's validity is firstly aimed at gathering convergent proofs based on the relations towards methods measuring similar constructs, the external criterion being the Revised Paranormal Belief Scale (RPBS) and the subscale of Esoteric and Personal Superstitious Thinking of the Contrastive Thinking Inventory (CTI). The second part of the research focuses on the validity proofs gathered in relation to the categorical variable - group affiliation - where we test a selective collection of the general public against a selection of technical and natural scientists and a selection of people attending courses with esoteric content. The research results confirm the method's reliability based on the split-half method and they also confirm a high coefficient of inner consistence of Cronbach's alpha. The results of the validation study show a strong correlation between the research inventory and selected scales of the CTI method as...

Assessment Centre Method Validation - Approaches and Options
Fousková, Petra ; Rymeš, Milan (advisor) ; Záškodná, Helena (referee)
The subject of this thesis is a validation of an assessment centre for employee selection, e.g. examining the validity of this method. Currently, the assessment centre represents an often used method of employee selection. At the same time, however, its implementation is demanding from the financial, time and personal perspective. If the assessment centre shall be considered an effective employee selection method, it is essential to pay attention to its psychometric aspects, especially the validity of its findings. First, the terms "assessment centre" and "validity" are defined and explained. Then, the thesis presents approaches and options of validation of the selection assessment centre based on scientific literature, articles and researches. Key Words assessment centre, employee selection, validation, validity

Assessment centre - validity, possibility and risks in the usage the company's procedure method
Doubková, Dagmar ; Bahbouh, Radvan (referee) ; Kirovová, Iva (referee)
My rigorous thesis is focused on the issue of Assessment Centre method (AC), its validity, contribution and objectivity, ethical rules and difficulties. The selection of competences studied by this method is discussed here as well. Strong and weak sides of the method are described by the SWOT analysis and possible opportunities and threats are pointed out in the work. The structure and the implementation of the AC method as well as its opportunities and real use in practice are described in the theoretical part of the work. This part of the work is also focused on the particular methods used within the AC methods. The differences between the Assessment Centres and Development Centres are brought up here. The AC method is compared with the other procedures which are used for the selection and development of employees. Opportunities and limitations of the validity of the measurement are discussed in this part of the work. The practical part of the work is devoted to the comparison of the AC method with other methods of selection and evaluation concerning the contribution and objectivity. The data analyzed in this comparison have been collected from the interviews with 27 HR managers and specialists. Four files describing the AC method from the point of view of the weak and strong sides are based on...

Validization of Marlowe-Crowne Social Desirability Scale in the Czech Context
Přibáňová, Tereza ; Remr, Jiří (advisor) ; Hendl, Jan (referee)
Diploma thesis deals with the process of validization of Marlowe-Crowne social desirability scale in the Czech context. Despite the fact that social desirability represents an error, which can disrupt validity of obtained data, there is no official Czech version of Marlowe-Crowne scale that could be used in surveys. The aim of this thesis is to create Czech translation of the scale and test its functionality. The Marlowe-Crowne scale is introduced from a theoretical point of view firstly, is discussed its creation, characteristics, its importance in relation to social desirability, critics and problems and possibilities and difficulties of its use in the new context. Further are discussed different ways of translation of research instruments, which could help to preserve their purpose, and method of cognitive interviews as a way of testing of new or adapted research instruments. Modified parallel translation of three translators was used for creation of Czech version of Marlowe-Crowne scale. Cognitive interview, based mostly on verbal protocols, were used for testing of finally translated scale to find out, if scale is applicable in the Czech context without any problems. Interviews were conducted with sixteen respondents with different sociodemographic characteristics. Thesis concludes that scale...

Enneagram-Development of Personality Type Test
Kilianová, Jana ; Bahbouh, Radvan (advisor) ; Niederlová, Markéta (referee)
The enneagram typology describes nine personality types and their mutual relations. It is a theoretical construct whose psychological validity is still being scientifically verified. The focus of this work is to develop a reliable and valid psychometric tool for recognizing the enneagram type and thereby verify the validity of this typology. The theoretical section describes the enneagram system on the basis of available literature and reviews research that set it in the psychological context. The empirical section deals with the development of the test to determine the ennea-type, with verification of its psychometric characteristics and criterion validity, and at the same time it examines the construct validity of enneagram typology. The criterion to review the validity is The Essential Enneagram Test by David Daniels, type identification by interview and self-identification. A quantitative data analysis was conducted on the sample of 300 persons of both, men and women of all ages using various kinds of statistical methods. The findings indicate that the tool developed to identify the ennea-type is reliable, of good psychometric quality and satisfactory criterion validity. Furthermore, the research supported the existence of nine enneagram types as per the theoretical construct, yet did not...
