    • Non-linear heart rate variability as a discriminator of internalizing psychopathology and negative affect in children with internalizing problems and healthy controls 

      Fiskum, Charlotte; Andersen, Tonje Grønning; Bornas, Xavier; Aslaksen, Per M.; Flaten, Magne A.; Jacobsen, Karl (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-23)
      Background: Internalizing psychopathology and dysregulated negative affect are characterized by dysregulation in the autonomic nervous system and reduced heart rate variability (HRV) due to increases in sympathetic activity alongside reduced vagal tone. The neurovisceral system is however, a complex nonlinear system, and nonlinear indices related to psychopathology are so far less studied in children. ...

      Sundgot-Borgen, Christine; Stenling, Andreas; Rosenvinge, Jan H; Pettersen, Gunn; Friborg, Oddgeir; Sundgot-Borgen, Jorunn; Kolle, Elin; Torstveit, Monica Klungland; Svantorp-Tveiten, Kethe M. E.; Bratland-Sanda, Solfrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-03)
      We examined both direct and indirect effects of the Healthy Body Image (HBI) intervention on positive embodiment among Norwegian high school students. In total, 2446 12th grade boys (43 %) and girls (mean age 16.8 years) from 30 schools participated in a cluster-randomized controlled study with the HBI intervention and a control condition as the study arms. We tested mediation models using path ...

    • Note to first-year university students: Just do it! In the end, the fact that you study may be more important than how you study. 

      Sæle, Rannveig Grøm; Dahl, Tove I.; Sørlie, Tore; Friborg, Oddgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-20)
      Education is important to society, yet many students do not complete the educations they start. In the present study of 426 students at a Norwegian university, we examined the predictive value of study-related variables with regard to student status one and five years after initial enrollment (stayers versus dropouts). The logistic regression analyses indicated that older students and students who ...

    • A novel experimental paradigm with improved ecological validity reveals robust action-associated enhancement of the N1 visual event-related potential in healthy adults 

      Balla, Viktória Roxána; Szalóki, Szilvia; Kilencz, Tünde; Dalos, Vera Daniella; Németh, Roland; Csifcsak, Gabor (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-11)
      The association between an action and its sensory consequence has been linked to our sense of agency (SoA). While ecological validity is crucial in investigating such a complex phenomenon, previous paradigms focusing on the cortical analysis of movement-related images used simplified experimental protocols. Here, we examined the influence of action-associated predictive processes on visual event-related ...

    • Now you see it, now you don’t: Solid and subtle differences between Hedonic and Eudaimonic Wellbeing 

      Thorsteinsen, Kjærsti; Vittersø, Joar (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-10)
      Data from an intensive longitudinal goal intervention study in Norway (N = 138) were used to test the assumption that hedonic (HWB) and eudaimonic (EWB) wellbeing reflect two distinct dimensions of wellbeing. Based on multilevel factor analyses, a path model and hierarchical regression analyses the paper aimed to demonstrate that a basic duality between the two kinds of wellbeing exists. Compared ...

    • Objective Versus Subjective Effort in Schizophrenia 

      Kreis, Isabel Viola; Moritz, Steffen; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-09)
      <i>Background and Objectives</i>: Performance on cognitive tasks is often impaired in individuals with schizophrenia (SCZ), possibly resulting from either cognitive deficits (e.g., limited working memory capacity) or diminished mental effort or both. Investment of mental effort itself can be affected by cognitive resources, task load, and motivational factors and has thus proven difficult to measure. ...

    • An observational study of compliance with the Scandinavian guidelines for management of minimal, mild and moderate head injury. 

      Heskestad, Ben Ottar; Waterloo, Knut; Ingebrigtsen, Tor; Romner, Bertil; Harr, Marianne Efskind; Helseth, Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The Scandinavian guidelines for management of minimal, mild and moderate head injuries were developed to provide safe and cost effective assessment of head injured patients. In a previous study conducted one year after publication and implementation of the guidelines (2003), we showed low compliance, involving over-triage with computed tomography (CT) and hospital admissions. The aim of the present ...

    • Om ansvar og å hjelpe seg selv 

      Gorecka, Marta Maria (Journal article; Tidsskriftartikkel, 2014)
      Som de sosiale dyrene vi er, søker vi råd hos våre medmennesker når vi har behov for hjelp og veiledning. Noen velger å gå til psykolog. Andre rådfører seg med sin(e) gode venn(er) for anerkjennelse og støtte. Andre går til prest for innspill. Noen velger å ikke gå til noen. Alt kan funke.

    • On the behavioral side of procrastination: Exploring behavioral delay in real-life settings 

      Svartdal, Frode; Sjur, Granmo; Færevaag, Fredrik Svartdal (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-16)
      This paper examines how procrastinators behave differently from non-procrastinators in implementing intended behavior. By focusing on time-related attributes of behavior, we demonstrate in five studies (aggregated N = 965) that onset delay seems to be a preferred option for procrastinators in common daily situations. Thus, when an action possibility is available for intended behavior, procrastinators ...

    • On the efficiency of neurally-informed cognitive models to identify latent cognitive states 

      Hawkins, Guy; Mittner, Matthias; Forstmann, Birte U; Heathcote, A (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-25)
      Psychological theory is advanced through empirical tests of predictions derived from quantitative cognitive models. As cognitive models are developed and extended, they tend to increase in complexity–leading to more precise predictions–which places concomitant demands on the behavioral data used to discriminate between candidate theories. To aid discrimination between cognitive models and, more ...

    • On the measurement of procrastination: Comparing two scales in six European countries 

      Svartdal, Frode; Pfuhl, Gerit; Nordby, Kent; Foschi, Gioel; Klingsieck, Katrin; Rozental, Alexander; Carlbring, Per; Lindblom-Ylänne, Sari; Rębkowska, Kaja (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-31)
      Procrastination is a common problem, but defining and measuring it has been subject to some debate. This paper summarizes results from students and employees (N = 2893) in Finland, Germany, Italy, Norway, Poland, and Sweden using the Pure Procrastination Scale (PPS) and the Irrational Procrastination Scale (IPS; Steel, 2010), both assumed to measure unidimensional and closely related constructs. ...

    • On the wonders of replication 

      Klevjer, Kristoffer (Conference object; Konferansebidrag, 2019)

    • One Size does not FIT all: Terapeuters erfaringer med bruk av tilbakemeldingsverktøyene i FIT i psykisk helsevern for barn og unge 

      Harildstad, Solveig Vårdal (Mastergradsoppgave; Master thesis, 2021-12-11)
      Denne studien har til formål å undersøke opplevelser og erfaringer til terapeuter som bruker Feedback Informed Treatment i psykoterapi med barn og unge. Tidligere studier har vist sprikende funn med tanke på bruk av FIT og betydning for behandlingseffekt. Det er behov for mer utdypende kunnskap om hvordan FIT virker, spesielt i arbeid med barn og unge. Seks terapeuter som jobber på BUP eller ...

    • One-Year Follow-Up of Healthy Older Adults with Electroencephalographic Risk for Neurocognitive Disorder after Neurofeedback Training 

      Alatorre-Cruz, Graciela C.; Fernández, Thaliá; Castro Chavira, Susana Angelica; González-López, Mauricio; Sánchez-Moguel, Sergio M.; Silva-Pereyra, Juan (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-15)
      Background: In healthy older adults, excess theta activity is an electroencephalographic (EEG) predictor of cognitive impairment. In a previous study, neurofeedback (NFB) treatment reinforcing reductions theta activity resulted in EEG reorganization and cognitive improvement.<p> <p>Objective: To explore the clinical applicability of this NFB treatment, the present study performed a 1-year follow-up ...

    • The Opioid Receptor Mu 1 (OPRM1) rs1799971 and Catechol-O-methyltransferase (COMT) rs4680 as genetic markers for placebo analgesia 

      Aslaksen, Per M; Forsberg, June Thorvaldsen; Gjerstad, Johannes (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-16)
      The placebo effect is considered the core example of mind-body interactions. However, individual differences produce large placebo response variability in both healthy volunteers and patients. The placebo response in pain, placebo analgesia, may be dependent on both the opioid system and the dopaminergic system. Previous studies suggest that genetic variability affects the function of these 2 systems. ...

    • Opplevd stigma og selv-stigma. Effekt på deprimerte ungdommers hjelpsøking og opplevde behov for hjelp 

      Olsen, Jørgen Mathias (Master thesis; Mastergradsoppgave, 2016-11-02)
      Depresjon hos ungdom er et viktig satsningsområde både for å forbedre livskvaliteten til ungdom og for å forebygge voksendepresjon. Mange ungdommer som sliter med depressive symptomer oppsøker ikke profesjonell hjelp. Dette skyldes blant annet at psykiske lidelser og depresjon er stigmatiserte tilstander. I denne studien undersøkte vi hvordan ungdommer mellom 15 og 20 år som er over klinisk ...

    • Opplevelsen av å være pårørende til partner med fødselsdepresjon: En systematisk litteraturgjennomgang og tematisk syntese

    • Optimizing the RMET to measure bias not performance differences 

      Pfuhl, Gerit; Leif, Ekblad (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-22)
      <p>Background: Human social interaction and communication is complex. Sending a verbal message is often accompanied by intonations, facial expressions, grimaces, and body postures. Nonverbal signals are potentially open for misinterpretation. One popular test for assessing the interpretation of facial expressions is the “Reading the Mind in the Eyes” Test (RMET). This test has been used to relate ...

    • Organisasjonsendring sett fra arbeidstakers perspektiv 

      Andersen, Betina Skovly (Master thesis; Mastergradsoppgave, 2015-05-04)
      Studien utforsket arbeidstakeres tanker og erfaring med organisasjonsendring i arbeidslivet. Studien søkte å innhente generelle refleksjoner fra arbeidstakere rundt emnet, og især om de opplever organisasjonsendring som episodisk eller kontinuerlig. Forskningen benyttet kvalitative intervju til innhenting av data fra ni arbeidstakere ansatt ved fire ulike organisasjoner på Østlandet i Norge. Deltakerne ...

    • Oversettelse og kulturell tilpasning av Attentional Function Index (AFI) 

      Utne, Inger; Grov, Ellen Karine; Kjerland, Linn Elise; Rønning, Mette; Rodrigues-Aranda, Claudia; Rasmussen, Hege Lund; Løyland, Borghild (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-22)
      Bakgrunn:<br>Antall krefttilfeller blant eldre øker sterkt, og i forbindelse med behandlingen kan kreftpasienter være utsatt for kognitive endringer. Mange av dem som overlever kreft, får nedsatt oppmerksomhet og konsentrasjon samt dårligere hukommelse. Attentional Function Index (AFI) er et instrument for å kartlegge kognitive prosesser, og det er utviklet i USA.<br>Hensikt:<br>Å redegjøre for ...
