The current study evaluated the next day consequences of a social night of drinking compared to a no alcohol night, with standardised mood and portable screen-based performance measures assessed in the morning at participants’ homes, and a breathalyser screen for zero alcohol. A mixed sex group (n = 20) took part in the study. Participants reported consuming on average 16.9 units (135 g) alcohol, resulting in a hangover rating of 60 (out of 100) compared to 0.3 following the no alcohol night. Statistical significance comparisons contrasting the hangover with the no alcohol condition revealed an increase in negative mood and irritability during hangover and an (unexpected) increase in risk and thrill seeking. Performance scores showed an overall slowing of responses across measures, but with less impact on errors. The results support the description of hangover as a general state of cognitive impairment, reflected in slower responses and reduced accuracy across a variety of measures of cognitive function. This suggests a general level of impairment due to hangover, as well as increased negative mood. The use of a naturalistic design enabled the impact of more typical levels of alcohol associated with real life social consumption to be assessed, revealing wide ranging neurocognitive impairment with these higher doses. This study has successfully demonstrated the sensitivity of home-based assessment of the impact of alcohol hangover on a range of subjective and objective measures. The observed impairments, which may significantly impair daily activities such as driving a car or job performance, should be further investigated and taken into account by policy makers.

Instrumental action and talking with others were the most frequent strategies used by adolescents to cope with cyberbullying. The structure of the coping strategies related to problematic Internet use and computer overuse is highly differentiated, revealing a new and promising area for future research.

IntroductionIn the Czech Republic, research of the schizophrenia spectrum suffers from a lack of standardized measuring instruments. The community assessment of psychic experiences (CAPE) has been used internationally to quantify positive, negative and affective symptoms associated with the spectrum and to screen individuals who may be in risk of developing a spectrum disorder.Aims and objectivesThis study aimed to develop a Czech version of the CAPE and to examine its psychometric properties in a nonclinical population.MethodsAn author with an expertise in the field and a subject-naïve author translated the CAPE into the Czech language. After a professional back-translation, the instrument's most suitable version was agreed upon. Lie-scale items were added to allow for an online circulation. The CAPE was administered to a large sample of participants alongside the Beck depression inventory (BDI-II).ResultsInternal consistency was assessed using the Cronbach's alpha. Internal structure was evaluated using confirmatory factor analysis and compared to the structure of the original. Criterion validity was examined through correlation analyses of the BDI-II scores and the total and subtotal CAPE scores.ConclusionsIt is determined whether the Czech version of the CAPE has sufficient reliability and validity to be recommended for research purposes. It is expected that further study of the CAPE as well as the introduction of additional tools will motivate the standardization of research, diagnosis and prevention of schizophrenia spectrum disorders in the Czech Republic.Disclosure of interestThe authors have not supplied their declaration of competing interest.
