A body of evidence suggests that Instagram problematic use and addiction have negative effects on the psychological well-being of young people. The Instagram Addiction Scale, a self-report tool assessing Instagram problematic use and addiction, has been developed recently. The aim of the present study was to validate the Instagram Addiction Scale in the Greek language and to assess its psychometric properties. An online and on-print self-report survey was conducted among Greek youth, aged between 18 and 24 years. The survey included the Instagram Addiction Scale, the Rosenberg Self-esteem Scale, the Perceived Stress Scale, and the Big Five Inventory. A total of 967 respondents participated in the study. The analysis suggested that the Greek version of the Instagram Addiction Scale has good psychometric properties. The principal component factor analysis for construct validity generated two subscales as the original instrument: social effect and impulsion. Internal consistency for the two subscales and the scale's total score was satisfactory, with Cronbach's α at 0.76, 0.85 and 0.88, respectively. Correlation analyses revealed positive associations between the perceived stress scale and social effect, and the Instagram Addiction Scale's total score (p<0.0001 and p=0.002 respectively). This is the first study validating the Instagram Addiction Scale in Greek youth, which can be used by researchers and practitioners for the evaluation of youth problematic use of Instagram.</p>","PeriodicalId":72893,"journal":{"name":"EMBnet.journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8494434/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39498241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first step in the identification of bullying is the detection of relevant signs and behaviours, with the use of appropriate instruments. The widely used Peer Relation Questionnaire (PRQ)has been developed to measure bullying behaviour in children and adolescents. The aim of this study was to translate and validate this instrument in the Greek language in a school sample of children and adolescents. A sample of 193 students (mean age ± SD 11.44 ± 1.26 years, girls 49.7%), was recruited from elementary and junior high schools of the public and private sector, in the capital of Athens, Greece. Along with the Peer Relation Questionnaire, the Stress in Children questionnaire and a structured inquiry regarding satisfaction from various aspects of life were used to assess the criterion validity of the Peer Relation Questionnaire. Results revealed good psychometric properties of the questionnaire in the Greek language. The principal component analysis resulted in two subscales that demonstrated an adequate internal consistency and a significant correlation with stress and satisfaction parameters, suggesting satisfying criterion validity. Meaningful associations between demographic characteristics and the subscales were also found. The Greek version of the Peer Relation Questionnaire-short form can be used as a valid tool to measure bullying behaviour in children and adolescents.</p>","PeriodicalId":72893,"journal":{"name":"EMBnet.journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8494435/pdf/nihms-1742270.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39498242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following the motto \"Standards make the world go round\", the outcomes of the COST Action are manifold and introduced some basic concepts and definitions that support a better understanding of the challenges and requirements. The results of this COST Action's network will be subject of a White Paper addressing the needs of standardisation, including a catalogue of requirements and recommendations to be disseminated to decision-makers at all levels to enable the implementation of standards in the daily workflow of research in academia and industry. The Action, ending this month, has given the opportunity to its members to tentatively presenting a set of preliminary requirements to develop further the harmonisation of standards. We hope this will inspire other Actions for the future.","PeriodicalId":72893,"journal":{"name":"EMBnet.journal","volume":"22 3 1","pages":"931"},"PeriodicalIF":0.0,"publicationDate":"2020-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83932453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exosome cargo heavily defines the vesicles' unique characteristics, and the cargo with the most intriguing prospects in its' biomedical applications is the non-coding RNAs. Non-coding RNAs, and specifically microRNAs are implicated in the regulation of many biological processes and have been associated with numerous diseases. Exosomes containing such important cargo can be used as biomarkers, therapeutic biomaterials, or even drug carriers. The potential media use of exosomes seems promising.
