An Updated Portrait of the Portuguese Web

This study presents an updated characterization of the Portuguese Web derived from a crawl of 48 million contents belonging to all media types (2.5 TB of data), performed in March, 2008. The resulting data was analyzed to characterize contents, sites and domains. This study was performed within the scope of the Portuguese Web Archive.POSC/EU, UMI

The Pemberton Happiness Index: Validation of the Universal Portuguese version in a large Brazilian sample

The Pemberton Happiness Index (PHI) is a recently developed integrative measure of well-being that includes components of hedonic, eudaimonic, social, and experienced well-being. The PHI has been validated in several languages, but not in Portuguese. Our aim was to cross-culturally adapt the Universal Portuguese version of the PHI and to assess its psychometric properties in a sample of the Brazilian population using online surveys.An expert committee evaluated 2 versions of the PHI previously translated into Portuguese by the original authors using a standardized form for assessment of semantic/idiomatic, cultural, and conceptual equivalence. A pretesting was conducted employing cognitive debriefing methods. In sequence, the expert committee evaluated all the documents and reached a final Universal Portuguese PHI version. For the evaluation of the psychometric properties, the data were collected using online surveys in a cross-sectional study. The study population included healthcare professionals and users of the social network site Facebook from several Brazilian geographic areas. In addition to the PHI, participants completed the Satisfaction with Life Scale (SWLS), Diener and Emmons' Positive and Negative Experience Scale (PNES), Psychological Well-being Scale (PWS), and the Subjective Happiness Scale (SHS). Internal consistency, convergent validity, known-group validity, and test-retest reliability were evaluated. Satisfaction with the previous day was correlated with the 10 items assessing experienced well-being using the Cramer V test. Additionally, a cut-off value of PHI to identify a happy individual was defined using receiver-operating characteristic (ROC) curve methodology.Data from 1035 Brazilian participants were analyzed (health professionals = 180Facebook users = 855). Regarding reliability results, the internal consistency (Cronbach alpha = 0.890 and 0.914) and test-retest (intraclass correlation coefficient = 0.814) were both considered adequate. Most of the validity hypotheses formulated a priori (convergent and know-group) was further confirmed. The cut-off value of higher than 7 in remembered PHI was identified (AUC = 0.780, sensitivity = 69.2%, specificity = 78.2%) as the best one to identify a happy individual.We concluded that the Universal Portuguese version of the PHI is valid and reliable for use in the Brazilian population using online surveys.Barretos Cancer Hospital internal research funds (PAIP)Canc Hosp Barretos, Grad Program Oncol, Barretos, BrazilBarretos Canc Hosp, Grp Pesquisas Cuidados Paliat & Qualidade Vida Re, Res Grp Palliat Care & Hlth Related Qual Life, Barretos, BrazilUniv Fed Sao Paulo UNIFESP, Mente Aberta Brazilian Ctr Mindfulness & Hlth Pro, Dept Prevent Med, Sao Paulo, BrazilHosp Israelita Albert Einstein, Sao Paulo, BrazilUniv Complutense, Sch Psychol, Madrid, SpainBarretos Canc Hosp, Dept Clin Oncol, Breast & Gynecol Div, Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, EPM, São Paulo, BrazilWeb of Scienc
