Analyzing aphasia data in a multidimensional symptom space

The utility of single-case vs. group studies has been debated in neuropsychology for many years. The purpose of the present study is to illustrate an alternative approach to group studies of aphasia, in which the same symptom dimensions that are commonly used to assign patients to classical taxonomies (fluency, naming, repetition, and comprehension) are used as independent and continuous predictors in a multivariate design, without assigning patients to syndromes. One hundred twenty-six Italian-speaking patients with aphasia were first classified into seven classic aphasia categories, based on fluency, naming, auditory comprehension, and repetition scales. There were two goals: (1) compare group analyses based on aphasia types with multivariate analyses that sidestep classification and treat aphasic symptoms as continuous variables; (2) present correlation-based outlier analyses that can be used to identify individuals who occupy unusual positions in the multivariate "symptom space." In the service of the first goal, group performance on an external validation measure (the Token Test) was assessed in three steps: analyses of variance based on aphasia type, regressions using the same cut-offs for fluency, naming, comprehension and repetition as independent but dichotomous predictors, and regressions using the same subscales as continuous predictors (with no cut-offs). More variance in Token Test performance was accounted for when symptoms were treated as continuous predictors than with the other two methods, though use of independent but dichotomous predictors accounted for more variance than aphasia taxonomies. Thus, if we by-pass classical taxonomies and treat patients as points in a multidimensional symptom space, better predictions are obtained. Outlier analyses show that group results depend on heterogeneity among patients, which can be used as a search tool to identify potentially interesting dissociations. Hence this multivariate group approach is complementary to and compatible with single-case methods.     

Midwives’ Approach to Genetic Diseases and Genetic Counseling in Denizli, Turkey

The purpose of this study was to evaluate Denizli midwives’ self-reported knowledge of genetic diseases and genetic counseling. Data was collected on forms that obtained information about midwives approaches to basic genetics, genetic disorders, and genetic counseling (response rate = 70.1%). The highest response rate of midwives describing themselves as “knowledgeable” about basic genetic information was for mitosis and meiosis with 4.8%, about genetic disorders was for phenylketonuria with 61.1%, and about genetic counseling was for recommending ultrasonography during pregnancy with 98.1%. The source for basic genetics information for 56.4% of participants was in their school level classes. None of the midwives felt that they had sufficient knowledge about genetic counseling or screening and 76.4% would like to attend an educational course. Even though the midwives have recognized their knowledge deficit they occasionally give genetic counseling. As a result of this study a genetics course is planned for midwives so they can actively participate in the prevention and early diagnosis of genetic diseases.     

Eating attitudes and their psychological correlates among Turkish adolescents

This study examined the eating attitudes and psychological characteristics of Turkish late adolescents. Seven hundred eighty-three university students were administered the Eating Attitudes Test, Rosenberg Self-Esteem Scale, State-Trait Anxiety Inventory, and Social Physique Anxiety Scale. More than one in ten (9.2% of the males and 13.1% of the females) had abnormal eating attitude scores. Chi-square analysis revealed that there were no significant differences in the prevalance of abnormal eating behaviors based on gender. Analysis of covariance indicated that participants who had disturbed eating attitudes had lower self-esteem, higher social physique anxiety, and higher trait anxiety than those who had normal eating attitudes. It was concluded that the prevalence of disturbed eating attitudes was high among these Turkish late adolescents, and that disturbed eating attitudes were related to several psychological characteristics.     

Are employees' ratings of coworkers' organizational citizenship behavior influenced by their own perceptions of organizational justice?'

Partial correlation analysis of questionnaire data from 62 of 65 employees of a Turkish company indicated that employees' own perceptions of organizational justice in terms of distributive, procedural, and interactional justice were related to how they rated their coworkers' organizational citizenship behavior. Specifically, all three two-way interactions between the justice variables were related to organizational citizenship behavior.     

Therapeutic factors in interactional inpatient groups: Results from a Turkish sample

Therapeutic factors in an inpatient group from Turkey are presented. A total of 40 patients were seen over a period of 2 years and each patient was given Yalom's (1983) 60-item therapeutic factor list on discharge. The first four most valued therapeutic factor groups were Catharsis, Existential Factors, Cohesiveness and Hope. There were significant differences in the highly valued factors in different diagnostic groups. Patients with diagnoses of anxiety/somatization and borderline/identity problem preferred factors resembling those in many out-patient studies. The results are discussed in the light of relevant literature.     

Present mood states in Brazilian night nurses

Variations in the state of momentary emotions of Brazilian hospital nurses on day and night shifts were recorded. Ten graduate nurses working on day and night shifts in the clinical ward of hospitals completed the Present Mood States List of Engelmann at the beginning and end of the first and last days of each shift. Analysis indicated (a) nurses had a stable emotional profile, present at the working shift, and (b) variations in present mood states related to specific effects of shift work were observed when comparisons were made between the present mood states at the beginning and end of each shift duty.     

Genetic Screening Services Provided in Turkey

In Turkey, the rate of consanguineous marriage is quite high (22–24 %) and as a result, the incidence of autosomal recessive diseases and congenital anomalies is also very high and gives rise to a serious public health problem. In the last three decades, great effort has been made to avoid increases in the prevalence of these hereditary diseases. For this purpose, population-based premarital, prenatal, neonatal and adult genetic screening programs are performed in various centers such as Community Health Centers, Early Diagnosis of Cancer and Education Centers (KETEM), Prenatal and Neonatal Departments of Universities and State Hospitals and Thalessemia Screening Centers. Such centers are staffed by health professionals including physicians, family physicians, nurses, midwives, biologists and medical geneticists. Genetic counseling is also provided to patients attending these centers after screening tests are performed. Since there are no specialized training programs for genetic counselors, genetic counseling is generally provided by doctors or medical geneticists. The aim of this paper is to give an overview of the genetic screening services provided in Turkey, the prevalence of genetic diseases and the design of intensive educational programs for health professionals.     

Body image satisfaction and anxiety of a Turkish sample of university students with skin diseases

The aim of this study was to evaluate perception of body image and anxiety of 221 university students presenting to the dermatology outpatient clinic with a skin disease and 205 students without skin disease. Analysis of anxiety and body image scores yielded differences by sex and age in both groups. The group with skin disease had lower scores on body image. Acne vulgaris seems to be the most disturbing among the skin diseases, and this was more prominent in younger patients.     

Fragility of Happiness Beliefs Across 15 National Groups

The belief that happiness is fragile—that it is fleeting and may easily turn into less favourable states—is common across individuals and cultures. However, not much is known about this belief domain and its structure and correlates. In the present study, we use multigroup confirmatory factor analysis and multilevel modelling to investigate the measurement invariance, cross-level isomorphism, predictive validity, and nomological network of the fragility of happiness scale across 15 nations. The results show that this scale has good statistical properties at both individual and cultural levels, and is associated with relevant psycho-social concepts in expected directions. The importance of the results, limitations, and potential directions for future research are discussed.
