    Sammanfattning :  The aim with this thesis was to describe, exemplify and develop theory for reference values and diagnostic tests, especially focusing on the variability between individuals. To facilitate interpretation of medical information it is common to establish some kind of limit. There are several different rationales for the choice of such a limit. LÄS MER

  2. 2. A perfect score : Validity arguments for college admission tests

    Författare :Per-Erik Lyrén; Christina Stage; Marie Wiberg; Simon Wolming; Stephen G. Sireci; Umeå universitet; []
    Nyckelord :college admission tests; SweSAT; validity; interpretive arguments; predictive validity; equating; item revisions; subscores;

    Sammanfattning : College admission tests are of great importance for admissions systems in general and for candidates in particular. The SweSAT (Högskoleprovet in Swedish) has been used for college admission in Sweden for more than 30 years, and today it is alongside with the upper-secondary school GPA the most widely used instrument for selection of college applicants.

  3. 3. Chronic intraoral pain - assessment of diagnostic methods and prognosis

    Författare :Maria Pigg; Malmö högskola; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuropathic pain; Orofacial pain; Trigeminal pain; Clinical studies; Prognosis; Diagnostic methods; Quantitative sensory testing; QST; Chronic pain; Endodontics;

    Sammanfattning : The overall goal of this thesis was to broaden our knowledge of chronic intraoral pain. The research questions were:•What methods can be used to differentiate inflammatory, odontogenic tooth pain from pain that presents as toothache but is non-odontogenic in origin?•What is the prognosis of chronic tooth pain of non-odontogenic origin, and which factors affect the prognosis?Atypical odontalgia (AO) is a relatively rare but severe and chronic pain condition affecting the dentoalveolar region.
