  1. 1. Some Aspects on Confirmatory Factor Analysis of Ordinal Variables and Generating Non-normal Data

    Författare :Hao Luo; Fan Yang-Wallentin; Johan Lyhagen; Karl Jöreskog; Marie Wiberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; confirmatory factor analysis; ordinal variables; maximum likelihood; weighted least squares; polychoric correlation; non-normal data; Fleishman s method; Monte Carlo simulation; Statistics; Statistik; Statistics; Statistik;

    Sammanfattning : This thesis, which consists of five papers, is concerned with various aspects of confirmatory factor analysis (CFA) of ordinal variables and the generation of non-normal data. The first paper studies the performances of different estimation methods used in CFA when ordinal data are encountered. LÄS MER

  3. 2. Mindfulness-Based Cognitive Therapy in Primary Care: Clinical Applications and Analysis of the Five Facet Mindfulness Questionnaire (FFMQ)

    Författare :Josefine Lilja; Göteborgs universitet; []

    Sammanfattning : The overall objective of this thesis is to analyse the concept of mindfulness as measured by the Five Facet Mindfulness Questionnaire (FFMQ) and its clinical usefulness in primary care through group Mindfulness-Based Cognitive Therapy (MBCT). Because no Swedish version of the FFMQ was available, that became the starting point of this research project. LÄS MER

  4. 3. When thoughts seem more than just thougths : body image-related cognitive fusion and its role in eating psychopathology

    Författare :Ines Trindade; Cláudia Ferreira; Portugal Coimbra University of Coimbra; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Clinical Psychology; Acceptance and commitment Therapy; body image-related cognitive fusion; cognitive fusion; eating psychopathology; assessment; Confirmatory Factor Analysis; body dissatisfaction; social comparison; mediation analysis; Psicologia Clínica; Terapia de Aceitação e Compromisso; fusão cognitiva relacionada com a imagem corporal; fusão cognitiva; psicopatologia alimentar; avaliação; Análise Fatorial Confirmatória; insatisfação corporal; comparação social; análise mediacional;

    Sammanfattning : Recent studies have revealed that cognitive fusion underlies psychological inflexibility and, as result, a wide range of psychopathology as well. It is portrayed as the extent to which one gets caught up in the content of his or her thoughts while addressing them as if they were facts rather than an interpretation of reality. LÄS MER

  5. 4. A covariance structure analysis approach to the errors-in-variables estimation problem

    Författare :David Kreiberg; Fan Yang-Wallentin; Håkan Hjalmarsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; System identification; errors-in-variables models; structural equation modeling; confirmatory factor analysis; minimum distance estimator; separable nonlinear least squares; Statistics; Statistik;

    Sammanfattning : It is a well-known fact that standard regression techniques, when applied to errors-in-variables (EIV) models, lead to biased and inconsistent parameter estimation. The work presented in this thesis address the EIV estimation problem using covariance structure analysis (CSA). LÄS MER
