“…The few studies employing each paradigm also meant that there would not have been enough power to adequately analyze them separately. However, a recent meta-analysis of 90 studies of obsessive-compulsive symptom induction in clinical and nonclinical samples showed similar results across a range of induction procedures (77). This provides some support for our nonsignificant comparison between studies using symptom provocation with pictures versus other paradigms.…”

It takes a village to raise a child and even more to raise a scientist, and this thesis would not be possible without years of work by my supervisors. I wish to thank Gerd Kvale and Bjarne Hansen for bothering to answer an email from me, a naïve psychology student, in November 2013. I had just received an offer to revise and resubmit my first article by a slightly confused editor who probably didn't understand what to do with a review paper written by a student with no supervisor. Gerd and Bjarne decided to give me a chance to work as a research assistant, which became the first building block of my PhD and our first paper together (Thorsen, van den Heuvel, Hansen, & Kvale, 2015). I wish to thank Bjarne and Gerd for showing how to combine being a caring person, clinician, and scientist. In addition, I thank them for trusting eager new students with important work and for guiding both patients and students to help them prosper. I wish to thank Odile van den Heuvel for her kind, intensive, generous, and enlightening guidance on how to combine living a good life and doing science. I remember travelling to Amsterdam for the first time in June 2014, then an eager and anxious 23-year old. However, my anxiety was soon lifted by Odile, the members of her research group, and her lovely family. I especially wish to thank her for her utmost generosity in inviting to me to live with her and her family for many of my visits to Amsterdam. Words cannot express my gratitude to my supervisors, and I look forward to working and spending time together in the future. I wish to thank my family and friends which make both life and work meaningful. I especially wish to thank Stella J. de Wit for guidance, discussions, and lots of fun throughout my PhD. I also thank her for inviting me to get to know her dear family. My visits to Weesp are very dear to me,

“…A limitation of the dirty-kiss task is that it is most appropriate for women ( Elliott and Radomsky, 2009 ). Future research should thus seek to use alternative methods for evoking mental contamination ( De Putter et al, 2017 ) in order to replicate the present findings among samples consisting of both sexes. By using alternative evoking sources and other samples, future research can help address whether metacognitive beliefs generally account for mental contamination severity or whether the impact of those beliefs seems most relevant in the context of posttraumatic stress.…”

Metacognitive Beliefs Predict Greater Mental Contamination Severity After an Evoking Source

Mental contamination occurs when individuals experience feelings of internal dirtiness and distress in the absence of physical contact with a contaminant. Women who experience sexual trauma frequently report mental contamination. The self-regulatory executive function (S-REF) model proposes that metacognitive beliefs contribute to the appraisal and regulation of thinking, leading to expectations that metacognitive beliefs would predict greater mental contamination severity following an evoking source. Women who reported directly experiencing sexual trauma (N = 102) completed self-report measures of metacognitive beliefs and covariates during an online study session, and subsequently completed a task that evoked mental contamination during a follow-up in-person study session. Metacognitive beliefs surrounding the uncontrollability and danger of thoughts, cognitive confidence, and the need to control thoughts positively correlated with mental contamination severity following the evoking source. Metacognitive beliefs surrounding the uncontrollability and danger of thoughts predicted greater mental contamination severity following the evoking source in multivariate analyses that statistically controlled for baseline mental contamination severity, trait anxiety, and overlap among the metacognitive beliefs. The present results provide preliminary support for the S-REF model as a potential framework for conceptualizing mental contamination.

“…It may be that the processes involved in the onset and maintenance of clinical OCD are not comparable to those in subclinical obsessive compulsive symptoms. However, several recent review articles have found strong support for the validity of using analogue samples in OCD research (Abramowitz et al, 2014;De Putter et al, 2017;Gagné et al, 2018a).…”

Background: The Salkovskis (1999) model of obsessive compulsive disorder (OCD), which emphasizes the role of inflated responsibility, has proven highly influential in both the understanding and treatment of OCD. Aims: This study aimed to empirically test several core processes of this model. Method: The individual components of the model were measured using multiple indicators in a sample of undergraduate students (n = 170), and confirmatory factor analyses were used to ascertain the most reliable, valid and theoretically consistent latent variables. Structural equation modelling was used to test proposed relations between latent constructs in the model. Results: The inflated responsibility model was a good fit for the data in the present sample. As predicted by the model, misinterpretations of intrusive thoughts as indicating personal responsibility fully mediated the relationships between responsibility beliefs and counterproductive safety strategies, neutralizing actions and mood changes. Conclusions: The Salkovksis (1999) inflated responsibility model of OCD is empirically supported in the present sample of undergraduate students, lending support to the proposed mechanisms in the model and supporting prior evidence.
