Quality of life assessment in Turkish patients with schizophrenia and their relatives

Quality of life of first-degree relatives living in the same household with patients having schizophrenia has not been sufficiently explored. 30 patients with schizophrenia (16 women, 14 men), diagnosed using DSM-IV criteria, 31 of their relatives (15 women, 16 men), and 34 control subjects (21 women, 13 men) were included in the study. The mean age of the patients, their relatives, and the control subects were 39.8 +/- 10.9, 58.1 +/- 12.5 and 37.3 +/- 17.0, respectively. The World Health Oranization Quality of Life-Brief Form was administered to all subjects. Quality of life was worse for the patient group than for their relatives and control subjects, but relatives of the patients and control subjects were not significantly different on Quality of life. Quality of life was negatively correlated with the severity of psychopathology and extrapyramidal side effects induced by antipsychotic drugs in the patients.     

The Endorsement of Minority Rights: The Role of Group Position, National Context, and Ideological Beliefs

The present research was conducted in the Netherlands and used an experimental design to examine the endorsement of minority rights among Turkish and Kurdish participants in two framed, national contexts: the Netherlands and Turkey. In the Dutch context, each group is a minority, whereas in the Turkish context the Kurds are an oppressed national minority and the Turks are the national majority. The results showed that the Turks were less in favor of minority rights in the Turkish context than in the Dutch context, whereas the Kurds were more in favor of minority rights in the Turkish than in the Dutch context. In addition, the endorsement of minority rights was related to beliefs about majority rule, state unity, and ingroup identification, as well as to cultural diversity and perceived pervasive discrimination. The associations with the former three measures differed between the two groups and the two national contexts, whereas the latter two measures had main effects on the endorsement of minority rights.     

Relationships between Turkish Eighth-Grade Students’ Oral Reading Efficacy,Reading Comprehension and Achievement Scores on a High-Stakes Achievement Test

The present study aimed to explore the relation between students’ oral reading efficacy, reading comprehension, and academic performance on a nationwide high school placement exam (TEOG). The students were selected from a public middle school. The students’ oral reading efficacy, comprehension, and TEOG achievement scores were obtained to figure out the relations between them. The students’ TEOG results were obtained from the school administration. The findings revealed that there were statistically significant relations between oral reading efficacy, reading comprehension and TEOG achievements. Particularly, students’ reading comprehension and accuracy skills together explained 57% of variance in overall TEOG achievements.     

Modeling of variables related to problematic social media usage: Social desirability tendency example

Social media usage has been popular for the last decade. Individuals use their social media environments for various reasons such as to socialize, play games, have fun and share posts. Overuse of these environments may lead to negative psychological and behavioral consequences for individuals. Additionally, it increases the worries about potential addicted/problematic use of social media. In this study, it is aimed to determine the level of problematic social media usage of participants who are active social media users and to analyze the relationships between problematic social media usage and various personal characteristics and social variables. Study in relational screening model is carried out with the participation of 580 volunteers. Partial least squares (PLS) structural equation modeling is used to analyze the data obtained through various scale according to the research model. The structural equation modeling analysis shows that there is a significant relationship between problematic social media usage and the daily time of social media usage, the use of frequency of social media for recognition, publicity, communication/interaction and education, loneliness, and social anxiety. The variable which shows higher correlation between problematic social media usage is social anxiety.     

Religious identity consolidation and mobilization among Turkish Dutch Muslims

This paper investigates religious identity consolidation in terms of the endorsement of the rights of Dutch Muslims to publicly express their identity, and identity mobilization in terms of the attitude towards normative forms of political organization. Identity consolidation and mobilization were examined as a function of the content of Muslim identity. A distinction was made between an individualized and a communal interpretation of what it means to be a Muslim, in addition to orthodox belief. Personal meaning and personal certainty as two aspects of an individualized interpretation were found to be positively associated to the endorsement of Muslim expressive rights, but not to the attitude towards political organization. Behavioural involvement and Muslim group interdependence were positively associated with identity organization. Orthodoxy was related to both identity consolidation and mobilization. Theoretical implications of these results are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

Ethical Issues in Neuromarketing: “I Consume,Therefore I am!”

Neuromarketing is a recent interdisciplinary field which crosses traditional boundaries between neuroscience, neuroeconomics and marketing research. Since this nascent field is primarily concerned with improving marketing strategies and promoting sales, there has been an increasing public aversion and protest against it. These protests can be exemplified by the reactions observed lately in Baylor School of Medicine and Emory University in the United States. The most recent attempt to stop ongoing neuromarketing research in France is also remarkable. The pertaining ethical issues have been continuously attracting much attention, especially since the number of neuromarketing companies has exceeded 300 world-wide. This paper begins with a brief introduction to the field of neurotechnology by presenting its current capabilities and limitations. Then, it will focus on the ethical issues and debates most related with the recent applications of this technology. The French Parliament’s revision of rules on bioethics in 2004 has an exemplary role in our discussion. The proposal by Murphy et al. (2008) has attracted attention to the necessity of ethical codes structuring this field. A code has recently been declared by the Neuromarketing Science and Business Association. In this paper, it is argued that these technologies should be sufficiently discussed in public spheres and its use on humans should be fully carried out according to the ethical principles and legal regulations designed in line with human rights and human dignity. There is an urgent need in the interdisciplinary scientific bodies like ethics committees monitoring the research regarding the scientific and ethical values of nonmaleficence, beneficence, autonomy, confidentiality, right to privacy and protection of vulnerable groups.     

Adaptation of a Muslim Spiritual Attachment Scale (God attachment) for Turkish Muslims: a validity and reliability study

ABSTRACT

Despite the importance of a believer’s attachment relationship with God for mental health, there are few measures relevant to Muslims, and little work on cross-cultural validation of such measures. The objective of the present study was to examine the validity and reliability of the Muslim Spiritual Attachment Scale (M-SAS) in Turkish Muslim samples. In analyzing the data, three different samples of college students (N?=?525, N?=?341, and N?=?47 respectively) were used. The validity and reliability of M-SAS were examined through exploratory factor analysis, confirmatory factor analysis, the internal consistency coefficient and the split-half reliability coefficient. Results supported a three-factor model of M-SAS with good reliability for the factors, and convergence with an alternative God Attachment measure. As a result, it may be concluded that M-SAS can be used as a valid and reliable measurement instrument in Turkish Muslim samples. The results are discussed in the light of the relevant literature.     

Relationship Between Miscarriage and Dysfunctional Cognitions About Trauma,Coping Mechanisms,and Posttraumatic Growth

Many studies have described grief and psychiatric symptomatology as a typical feature following miscarriage. How women who had a miscarriage (MG) respond to trauma in terms of negative cognitions about their selves and the world, the coping strategies they employ to overcome the effects of the trauma, and what factors might be indicative of posttraumatic growth (PTG) in this population have not been extensively studied so far. We aimed to identify whether women who had a miscarriage (N = 74 vs. N = 82 control subjects) exhibited higher levels of psychological distress symptoms, dysfunctional cognitions, and maladaptive coping strategies, and whether women with lower PTG employed more maladaptive coping strategies, and reported higher levels of dysfunctional cognitions. Group comparisons according to the diagnostic groups based on self-report measures for depression, anxiety, posttraumatic stress disorder and according to the level of PTG, and stepwise linear regression analyses with PTG as the outcome were performed. Our study demonstrated that the MG does not necessarily differ from the control group on some measures of psychopathology, coping mechanisms, dysfunctional cognitions, or PTG. Yet, the MG who exhibited higher levels of PTG had specific predictors, and women with a psychiatric diagnosis differed from participants with no diagnoses on some measures of dysfunctional cognitions, coping mechanisms, and PTG. Further studies with a prospective design could further clarify the needs of the MG requiring psychotherapeutic interventions.     

Adaptive criterion setting in perceptual decision making

Pigeons responded in a perceptual categorization task with six different stimuli (shades of gray), three of which were to be classified as "light" or "dark", respectively. Reinforcement probability for correct responses was varied from 0.2 to 0.6 across blocks of sessions and was unequal for correct light and dark responses. Introduction of a new reinforcement contingency resulted in a biphasic process of adjustment: First, choices were strongly biased towards the favored alternative, which was followed by a shift of preference back towards unbiased choice allocation. The data are well described by a signal detection model in which adjustment to a change in reinforcement contingency is modeled as the change of a criterion along a decision axis with fixed stimulus distributions. Moreover, the model shows that pigeons, after an initial overadjustment, distribute their responses almost optimally, although the overall benefit from doing so is extremely small. The strong and swift effect of minute changes in overall reinforcement probability precludes a choice strategy directly maximizing expected value, contrary to the assumption of signal detection theory. Instead, the rapid adjustments observed can be explained by a model in which reinforcement probabilities for each action, contingent on perceived stimulus intensity, determine choice allocation.     

The Search for Non-Medical Treatment by Patients with Psychiatric Disorders

Patients in Turkey frequently seek help from non-physicians such as hodjas and fortune-tellers. The aim of this study is to assess the prevalence, reasons for and results of the search for non-medical help by patients with psychiatric disorders. It was determined that 42.2% of patients consulted a hodja or a fortune-teller, and many (23.1%) were either the subject of prayers or else were advised to pray themselves as treatment. Considering that a significant number of patients seek non-medical treatment, it is thought that people should be informed about psychiatric disorders, therapies, and how to obtain them.All of the authors are M.D.s at Ondokuz Mayis University in Samsun, Turkey.
