Does long term use of piracetam improve speech disturbances due to ischemic cerebrovascular diseases?

Aphasia causes significant disability and handicap among stroke survivors. Language therapy is recommended for aphasic patients, but not always available. Piracetam, an old drug with novel properties, has been shown to have mild beneficial effects on post-stroke aphasia. In the current study, we investigated the effects of 6 months treatment with piracetam on aphasia following stroke. Thirty patients with first-ever ischemic strokes and related aphasia were enrolled in the study. The scores for the National Institutes of Health Stroke Scale (NIHSS), Barthel Index (BI), modified Rankin Scale (mRS), and Gülhane Aphasia Test were recorded. The patients were scheduled randomly to receive either 4.8 g piracetam daily or placebo treatment for 6 months. At the end of 24 weeks, clinical assessments and aphasia tests were repeated. The level of improvement in the clinical parameters and aphasia scores was compared between the two groups. All patients had large lesions and severe aphasia. No significant difference was observed between the piracetam and placebo groups regarding the improvements in the NIHSS, BI and mRS scores at the end of the treatment. The improvements observed in spontaneous speech, reading fluency, auditory comprehension, reading comprehension, repetition, and naming were not significantly different in the piracetam and placebo groups, the difference reached significance only for auditory comprehension in favor of piracetam at the end of the treatment. Piracetam is well-tolerated in patients with post-stroke aphasia. Piracetam taken orally in a daily dose of 4.8 g for 6 months has no clear beneficial effect on post-stroke language disorders.     

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.     

Color and number preferences of patients with psychiatric disorders in eastern Turkey

Color and number preferences have not been studied in healthy sublets and psychiatric patients in Turkey. The study group consisted of a total of 500 patients who had been referred to Firat University Medical Faculty Psychiatry Clinic between March and July 2000 and diagnosed with a psychiatric disorder according to DSM-IV criteria. Preferred colors were requested as a selection from the Lüscher Color Test. Then the patients were told to choose a number between 0 and 9. Green was the most frequently preferred of all colors and the number 3 was the most preferred number. Our results demonstrate that patients' choice of color and number reflect the region's religious and cultural milieu.     

Procrastination,Self‐Downing,Self‐Doubt,and Rational Beliefs: A Moderated Mediation Model

A cross‐sectional study tested the integrated effects of self‐downing, self‐doubt, and rational beliefs on procrastination in a sample of Turkish undergraduate students (N = 315). Results suggest that both self‐downing and rational beliefs have a direct and interactive effect on self‐doubt, and self‐doubt mediates the relationship between self‐downing and procrastination. Results suggest that the indirect effect of self‐downing on procrastination via the mediation of self‐doubt may vary depending on the level of rational beliefs. Implications for counselors and future research directions are discussed.     

The role of environmental literacy,psychological distance of climate change,and collectivism on generation Z's collaborative consumption tendency

Parallel with increasing concerns about climate change and the emergence of sharing platforms, collaboration in consumption has become prominent, especially among Generation Z consumers. Drawing upon the self-determination and construal-level theories, the present study proposes a pioneering moderated-mediation model that delineates Generation Z consumers' collaborative consumption tendency. Data were collected among 455 respondents in an emerging economy (i.e., Turkey) via a non-probabilistic purposive sampling technique. Furthermore, a covariance-based structural equation modeling was utilized to test the proposed causal relationships between environmental literacy, collaborative consumption tendency, the psychological distance of climate change, and collectivism. The study findings highlighted that environmental literacy affects collaborative consumption tendency, while the strength of the relationship is augmented for respondents who were self-reportedly collectivists. Furthermore, the findings revealed that the psychological distance of climate change mediates the relationship between environmental literacy and collaborative consumption tendency, while the magnitude of the mediation effect is amplified in collectivist participants. Based on the empirical findings, the present study extends self-determination and construal-level theory while offering strategic directions and insights for sharing platform industry.     

Association of Fine Motor Loss and Allodynia in Fibromyalgia: An fNIRS Study

Recent studies showed that fine motor control dysfunction was observed in fibromyalgia (FM) syndrome as well as allodynia. However, brain signatures of this association still remain unclear. In this study, finger tapping task (FTT) and median nerve stimulation (MNS) were applied to both hands of 15 FM patients and healthy controls (HC) to understand this relationship. Hemodynamic activity was measured simultaneously using functional near-infrared spectroscopy (fNIRS). Experiments were analyzed separately by using 2x2 repeated measures ANOVA. Results for the FTT experiment revealed that HC showed higher activity than FM patients in bilateral superior parietal gyrus (SPG), left supramarginal gyrus (SMG) and right somatosensory cortex (SI). Furthermore, right-hand FTT resulted in higher activity than left-hand FTT in left SPG, left SI and right motor cortex (MI). In the MNS experiment, FM patients showed higher activity than HC in bilateral SPG, right SMG, right SI and right middle frontal gyrus (MFG). Negative correlation was observed in left SPG between FTT and MNS activities. Besides, MNS activity in left SPG was negatively correlated with left-hand pain threshold.This study revealed that left SPG might be an important indicator to associate fine motor loss and allodynia in FM.     

Procrastination and predictor variables among a group of dental students in Turkey

The aim of this study was to assess the prevalence of procrastination among a group of Turkish dental students and to determine the predictors and consequences of procrastination. A total number of 273 females and 179 males (aged between 18 and 28) were included in the study. Tuckman procrastination scale, Academic Life Satisfaction Scale, Concern over Mistake Scale, Poor Time Management Scale, Self-Doubt Scale, Irrational Beliefs about Studying Scale, Positive and Negative Affect Schedule and Life Satisfaction Scale were used to gather data. Results indicated that 50% of participants were more likely to procrastinate their academic assignments or tasks. Procrastination score did not differ according to gender. The findings suggested that procrastinating students had a higher level of poor time management, self-doubt and irrational beliefs about studying, and poor academic performance and well-being than their non-procrastinating counterparts. Preventive strategies are necessary to overcome procrastination which affects the academic achievement, satisfaction, and well-being of dental students.     

A matter of time: novel nouns mark object categories when delays are imposed

In previous work, preschool-aged children have revealed a specific expectation that novel count nouns (but not adjectives) will refer to object categories (but not to object properties or to thematic relations). However, in these tasks, children have been permitted to extend a novel word immediately after it has been introduced. The current experiments test the hypothesis that the noun-category bias is sufficiently robust to hold up even when a delay is imposed between a naming episode and the child’s opportunity for extension. To capture this phenomenon experimentally, we imposed delays of 30 s (Experiment 1) and 1 h (Experiment 2). Across both delay conditions, children in a ‘novel noun’ condition revealed a strong inclination to consistently choose other members of the same object category as the (previously named) target. Children in either a ‘novel adjective’ or ‘no word’ condition revealed no taxonomic inclination. These results establish the power of the noun-category bias in situations that more closely approximate some of the very real challenges that children face in mapping and extending novel words.     

Practical Applications of Generalizability Theory for Designing,Evaluating, and Improving Psychological Assessments

In this article, we illustrate how generalizability theory (G-theory) can extend traditional assessment methods for designing, improving, and evaluating results from both objectively and subjectively scored measures of individual differences. Our illustrations include quantification of multiple sources of measurement error, derivation of unique indexes of consistency for norm- and criterion-referenced interpretations of scores, estimation of score consistency when changing a measurement procedure, and disattenuation of correlation coefficients for measurement error. We also expand G-theory analyses beyond the item level to include parcels and split measures and highlight linkages among G-theory, classical test theory, and structural equation modeling. Computer code and sample data are provided in online supplements to help readers apply the demonstrated techniques to their own assessments.
