Psychiatric disorders are associated with cognitive dysfunction (CD), and reliable screening and follow-up of CD is essential both for research and clinical practice globally; yet, most assessments are in Western languages. We aimed to evaluate the test-retest reliability of the Turkish version of the Penn Computerized Neurocognitive Battery (PennCNB) to guide confident interpretation of results. Fifty-eight healthy individuals completed the PennCNB Turkish version in two sessions. After quality control, reliability analysis was conducted using Intraclass Correlation Coefficients (ICC), corrected for practice effects. Most measures were not significantly different between the sessions and had acceptable ICC values, with several exceptions. Scores were improved considerably for some memory measures, including immediate Facial Memory and Spatial Memory, and for incorrect responses in abstraction and mental flexibility, with correspondingly acceptable ICCs. Test-retest assessment of the Turkish version of the PennCNB shows that it can be used as a reliable real-time measurement of cognitive function in snapshot cross-sectional or longitudinal determinations. Preliminary validity assessment in this normative sample showed expected positive correlations with education level and negative correlations with age. Thus, the Turkish version of the PennCNB can be considered a reliable neuropsychological testing tool in research and clinical practice. Practice effects should be considered, especially when applied in short intervals. Significantly better performances in the retest, beyond practice effect, likely reflect nonlinear improvements in some participants who "learned how to learn" the memory tests or had insight on solving the abstraction and mental flexibility test.

© 2020 Elsevier LtdThe patho-etiology of mental disorders with onset in childhood or adolescence remains largely unknown. We conducted an umbrella review of meta-analyses (MAs) on environmental factors associated with mental disorders with onset in childhood/adolescence. We searched Pubmed-MEDLINE/EMBASE/PsycInfo databases, last search April 29th, 2020. Quality of MAs was measured with AMSTAR-2. Out of 6851 initial references, ten articles met inclusion criteria, providing 23 associations between 12 potential environmental factors and nine disorders (cases: 8884; N = 3,660,670). While almost half of the associations were nominally significant, none of them met criteria from either convincing or highly suggestive evidence. A single association was supported by suggestive evidence (maternal exposure to lithium or antipsychotics with neuromotor deficits), but it was affected by confounding by indication. Ten more associations had weak evidence, and 12 associations were not statistically significant. Quality of meta-analyses was rated as high in two, moderate in one, low in four, critically low in two, and not pertinent in one (individual participant data). Methodologically-sound research is needed in this field.

Diagnosis of cancer leads to multiple losses, all with the potential to initiate grief reactions in patients. The present study aims to contribute to the understanding of the experience of grief by patients with cancer in relation to perceptions of illness, with a focus on the mediating roles of identity centrality, stigma-induced discrimination, and hopefulness. The analyses indicated that these factors functioned as significant partial mediators. The results have implications in terms of supporting patients through the grieving process by working on the meaning of the illness for their identity and improving psychosocial environments to minimize discrimination and facilitate hope.

Background: Cognitions associated with craving and substance use are important contributors for the psychological theories of Substance use disorders (SUD), as they may affect the course and treatment. In this study, we aimed to validate Turkish version of two major scales 'Beliefs About Substance Use'(BSU) and 'Craving Beliefs Questionnaire'(CBQ) in patients with heroin use disorder and define the interaction of these beliefs with patient profile, depression and anxiety symptoms, with an aim to use these thoughts as targets for treatment. Methods: One hundred seventy-six inpatients diagnosed with heroin use disorder and 120 participants in the healthy comparison group were evaluated with CBQ, BSU, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and sociodemographic data questionnaire. Patient group was also evaluated with Addiction Profile Index. Reliability and validity analysis for scales were conducted. Linear regression analysis was conducted to evaluate the determinants of BSU and CBQ scores. Results: Cronbach alpha level was 0.93 for BSU and 0.94 for CBQ. Patient group showed significantly higher CBQ, BSU, BAI and BDI scores (p < 0.001). BSU score significantly correlated with API-substance use profile score, API-diagnosis, BAI, BDI and CBQ (p < 0.005), whereas CBQ scores significantly correlated with API-diagnosis, API-impact on life, API-craving, API-total score, BSU, BAI, BDI and amount of cigarette smoking (p < 0.002). Number of previous treatments and age of onset for substance use were not correlated with either BSU or CBQ. BAI and BDI scores significantly predicted BSU score, however only BDI score predicted CBQ score (p < 0.003). Conclusions: Craving beliefs were highly correlated with addiction profile. Anxiety and depression are significant modulators for patients' beliefs about substance use and depression is a modulator for craving and maladaptive beliefs, validating emotion-cognition interplay in addiction., NA
