• Change characteristics of health-related quality of life and its association with post-stroke fatigue at four-year follow-up 

      Garder Pedersen, Synne; Anke, Audny Gabriele Wagner; Løkholm, Mari Thoresen; Halvorsen, Marianne; Kirkevold, Marit; Heiberg, Guri Anita; Ørbo, Marte Christine; Friborg, Oddgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-04)
      The long-term consequences of stroke may be highly individual and multifaceted. The question of how such individual differences may unfold and change beyond the first year after stroke may be of substantial clinical interest regarding which subgroups show more favourable and unfavourable rehabilitation trajectories. The current study explored functional trajectories from 1 to 4 years post-stroke ...

      Background: Adults with intellectual disability (ID) have poorer physical and perceived health than the general population. Knowledge of perceived health predictors is both limited and important for guiding the development of preventive actions. The aims of this study were to investigate (1) the associations between perceived health and demographics, degree of ID, physical health conditions, and ...

      Background: In addition to symptoms of neurodevelopmental disorders, functional impairment is crucial to the determination of clinical significance. The aim of this study was to examine partial validity and usefulness of the Strengths and Difficulties Questionnaire’s (SDQ) impact supplement (SDQ impact) in measuring functional impairment in children and adolescents diagnosed with attention ...
    • Invisible emotional expressions influence social judgments and pupillary responses of both depressed and non-depressed individuals. 

      Laeng, Bruno; Sæther, Line; Holmlund, Terje; Wang, Catharina E.; Waterloo, Knut; Eisemann, Martin; Halvorsen, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      We used filtered low spatial frequency images of facial emotional expressions (angry, fearful, happy, sad, or neutral faces) that were blended with a high-frequency image of the same face but with a neutral facial expression, so as to obtain a “hybrid” face image that “masked” the subjective perception of its emotional expression. Participants were categorized in three groups of participants: healthy ...

    • Personality characteristics and vulnerability to depression : a cross-sectional and longitudinal perspective 

      Halvorsen, Marianne (Doctoral thesis; Doktorgradsavhandling, 2009-12-04)
      Depression is a serious disorder due to its highly relapsing and recurrent course, thereby highlighting the necessity to identify vulnerability factors in order to prevent and treat its course. The present thesis investigated temperament and character traits, dysfunctional attitudes, and early maladaptive schemas (EMSs) in clinically depressed (CDs), previously depressed (PDs), and never depressed ...
