  2. 1. The Measurement of Subjective Well-Being: Item Response Theory, Classical Test Theory, and Multidimensional Item Response Theory

    Author : Ali Al Nima; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Life Satisfaction; Negative Affect; Positive Affect; Harmoni in Life Subjective Well-Being; Item Response Theory; Classical Test Theory; Multidimensional Item Response Theory.;

    Abstract : For over 35 years, modern science has conceptualized happiness as subjective well-being, which has until recently been understood as a dual construct consisting of an affective component (positive and negative affect) and a cognitive component (life satisfaction). Nevertheless, for the last five years, theoretical work and both quantitative and qualitative empirical work have suggested that the concept of subjective well-being omits both a lay and an Eastern way of understanding happiness.

  4. 2. Test Design for Mean Ability Growth and Optimal Item Calibration for Achievement Tests

    Author : Jonas Bjermo; Frank Miller; Marie Wiberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; test design; item response theory; optimal experimental design; SweSAT; item calibration; vertical scaling; ability growth; computerized adaptive tests; Statistics; statistik;

    Abstract : In this thesis, we examine two topics in the area of educational measurement. The first topic studies how to best design two achievement tests with common items such that a population mean-ability growth is measured as precisely as possible. The second examines how to calibrate newly developed test items optimally. READ MORE

  5. 3. Adolescent mental health : time trends and validity of self-report measures

    Author : Ida Blomqvist; Eva Henje; Inga Dennhag; Anne Hammarström; Lotte Haverman; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescent; classical test theory; computer adaptive testing; cross-sectional; differential item functioning; graded response model; item banks; item response theory; measurement invariance; mental health; Patient-Reported Outcomes Measurement Information System; Reynolds Adolescent Depression Scale second edition; self-report measures; time trends; barn- och ungdomspsykiatri; Child and Youth Psychiatry;

    Abstract : Background: Studies of time trends of adolescent self-reported mental health suggest an increase of mental health symptoms globally. Unfortunately, several studies within the field have methodological problems, such as short time-period between measurements and different mental health measures over time. READ MORE

  6. 4. Achievement tests and optimal design for pretesting of questions

    Author : Mahmood Ul Hassan; Frank Miller; Steven Gilmour; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Achievement test; Equivalence theorem; Exchange algorithm; Item calibration; Item response theory model; Optimal experimental design; Statistics; statistik;

    Abstract : Achievement tests are used to measure the students' proficiency in a particular knowledge. Computerized achievement tests (e.g. GRE and SAT) are usually based on questions available in an item bank to measure the proficiency of students. READ MORE

  7. 5. Contributions to Kernel Equating

    Author : Björn Andersson; Fan Yang-Wallentin; Marie Wiberg; Alina A. von Davier; Jorge González; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; observed-score test equating; item response theory; R; equipercentile equating; asymptotic standard errors; non-equivalent groups with anchor test design; Statistics; Statistik;

    Abstract : The statistical practice of equating is needed when scores on different versions of the same standardized test are to be compared. This thesis constitutes four contributions to the observed-score equating framework kernel equating. READ MORE
