Personlighet, datorerfarenhet och upplevelseav datorfrustration

I och med informationsteknologins snabba framväxt i samhället ställs vi också inför problem som hur vi ska handskas med denna utveckling. Forskning visar att fenomenet datorrädsla kan bero på faktorer som exempelvis erfarenhet, personlighet, attityd eller kön. Syftet med denna studie är dock att undersöka eventuella samband mellan datorrädsla, personlighet samt datorerfarenhet. Nittio studenter vid Högskolan Dalarna agerade undersökningsdeltagare (UD) genom att svara på en enkät bestående av tre delar; bakgrundsfrågor, ett personlighetstest sammansatt av Eysenck Personality Inventory (EPI) samt åtta scenarier, där UD fick skatta sin självupplevda stressnivå i olika situationer. Studien visar att såväl neuroticism som datorerfarenhet skulle kunna predicera datorrädsla. Starkast effekt på den självskattade stressnivån hade dock variabeln kön. Man kan även dra slutsatsen att fenomenet datorrädsla inte är en specifik slags rädsla, utan till viss del hänger samman med andra fobier.

Matproblem och personlighet

The purpose of this study was to examine by means of Eysenck Personality Inventory (EPI), the relationship between Neuroticism, and self-rated eating problems. Altogether 105 respondents, mean aged 42,3 years, including 11 men and 94 women, participated by answering an Internet-based questionnaire comprising three different sections. Neuroticism correlated with self-rated eating problems (r=,468, p<0,01). By means of multiple regression analysis it was indicated that both Neuroticism (p<.001) and Body Mass Index (BMI) (p<.001) contributed significantly to the prediction of self-rated eating problems (multiple correlation (ß=.594). The study indicated that the personality only partly explained the variation of eating problems. The result was discussed in terms of significance of biological factors stressing changes in 5-HT levels triggering eating problems.

Personlighet och val av utbildning

Påverkar vår personlighet de utbildningsval vi gör i livet? Denna fråga ligger till grund för studien som gjordes på ekonom- och sjuksköterskestudenter på Uppsala Universitet. I studien deltog 120 personer och undersökningsdeltagarna (Ud) var jämnt fördelademellan ekonomer/sjuksköterskor och kvinnor/män. Studien genomfördes genom att Ud fick svara på 48 stycken påståenden som utgick från Eysenck Personality Inventory (EPI). Tidigare forskning har påvisat skillnader i personlighet mellan ekonom- och vårdstudenter. Syftet med studien var att undersöka om det fanns någon skillnad i personlighet mellan ekonom- och sjuksköterskestudenter. Studien visade inga signifikanta skillnader i personlighet mellan studentgrupperna. Den slutsats som drogs i denna studie, var att vår personlighet inte påverkar utbildningsvalen ekonom- och sjuksköterska.

Personlighetstyper och upplevelse av ett nytt arbetsstöd : undersökning gjord på Trafikverkets Intranät och anställda

In order to get a better understanding of the interaction between employees and their technical work tools one needs to know what factors influence the interaction. The purpose of this study was to examine if there is a correlation between the personality traits Extraversion (E) and Neuroticism (N), tested with Eysenck Personality Inventory (EPI), and experience of the new Intranet among employees at The Swedish National Transport Administration (SNTA), and also to gather information of employees’ opinions about the new Intranet. A survey, containing questions about the Intranet and a personality test (EPI), was posted on SNTA’s Intranet for eight workdays (N = 88, females = 53, males = 35). A Multiple Regression showed no significant correlations between personality traits (E/N) and experience of the new Intranet. Considering the study’s low Power (.34) one cannot draw any conclusions of the statistical tests. A majority of the participants did not think that the new Intranet is better than the old one, and thought it was difficult to find necessary information on the Intranet at first. However, they did not think this had a negative effect on the time it took to accomplish their work tasks. For upcoming studies more participants are required (preferable more than 200) and the survey should not only be available via computers in order to reach people who is not frequent users of computers.

Methodology used in studies reporting chronic kidney disease prevalence : a systematic literature review

BACKGROUND: Many publications report the prevalence of chronic kidney disease (CKD) in the general population. Comparisons across studies are hampered as CKD prevalence estimations are influenced by study population characteristics and laboratory methods. METHODS: For this systematic review, two researchers independently searched PubMed, MEDLINE and EMBASE to identify all original research articles that were published between 1 January 2003 and 1 November 2014 reporting the prevalence of CKD in the European adult general population. Data on study methodology and reporting of CKD prevalence results were independently extracted by two researchers. RESULTS: We identified 82 eligible publications and included 48 publications of individual studies for the data extraction. There was considerable variation in population sample selection. The majority of studies did not report the sampling frame used, and the response ranged from 10 to 87%. With regard to the assessment of kidney function, 67% used a Jaffe assay, whereas 13% used the enzymatic assay for creatinine determination. Isotope dilution mass spectrometry calibration was used in 29%. The CKD-EPI (52%) and MDRD (75%) equations were most often used to estimate glomerular filtration rate (GFR). CKD was defined as estimated GFR (eGFR) <60 mL/min/1.73 m(2) in 92% of studies. Urinary markers of CKD were assessed in 60% of the studies. CKD prevalence was reported by sex and age strata in 54 and 50% of the studies, respectively. In publications with a primary objective of reporting CKD prevalence, 39% reported a 95% confidence interval. CONCLUSIONS: The findings from this systematic review showed considerable variation in methods for sampling the general population and assessment of kidney function across studies reporting CKD prevalence. These results are utilized to provide recommendations to help optimize both the design and the reporting of future CKD prevalence studies, which will enhance comparability of study results.
