Development and Validation of the Morphing Fear Questionnaire (MFQ)

The current status of mental contamination in obsessive compulsive disorder: A systematic review

BACKGROUND AND OBJECTIVES

Over the past 25 years Mental Contamination (MC) has become recognised as a distinct construct, particularly in relation to Obsessive Compulsive Disorder (OCD). MC is defined as feelings of contamination, often located internally, that arise in the absence of contact with a contaminant, with the source proposed to be human. Despite considerable interest from researchers and clinicians, there has not been a systematic review on the relationship between MC and OCD. Therefore, a systematic review was conducted to summarise and synthesise the current status of phenomenological and experimental evidence, mechanisms, assessment, measurement, and treatment of MC in OCD (PROSPERO: CRD42021223119).

METHODS

All study designs were eligible provided the focus of the study was on MC and the implications of the study were linked to OCD. We searched PsychINFO, Embase, Medline, Ethos, ProQuest, conference abstracts and trial registries between 1990 and 2021. The Mixed Methods Appraisal tool was used to assess methodological quality of included studies.

RESULTS

We found 58 reports with a total of 67 studies that met criteria for inclusion in the review. Twenty-three of these studies used clinical samples, 28 were experimental, 12 focused on phenomenology and 8 addressed treatment. The quality of the studies was variable.

LIMITATIONS

Grey literature was not included, thus there may be further unpublished MC studies that have not been included in the review.

CONCLUSIONS

Based on the findings, mental contamination is a robust clinical construct within OCD that has important implications for understanding and treating the disorder.

Clinical characteristics of transformation obsessions in obsessive-compulsive disorder: A psychopathological study

BACKGROUND

The obsession of turning into another person (transformation obsessions [TO]), and its related compulsions have been initially conceptualised as a form of mental contamination. Nevertheless, it has remained understudied in the current obsessive-compulsive disorder (OCD) literature. In parallel, disturbances of the self have been identified as markers of prodromal psychosis in patients with schizophrenia. Based on the later association, this study aimed to investigate the sociodemographic and clinical correlates of TO.

METHODS

In all, 1001 OCD outpatients from the Brazilian OCD Research Consortium were included in this study. Several semi-structured and structured instruments were used to compare 48 OCD patients with TO with 953 OCD patients without TO. A repression model investigated the relationships between the presence of current TO and statistically significant univariate test outcomes.

RESULTS

Participants with TO presented an overall younger age, a longer period of time between the onset of the OCD symptoms and an OCD diagnosis, greater severity of the sexual/religious dimension and increased suicidality symptoms.

CONCLUSIONS

These results indicate that TO may be better conceptualised as a form of forbidden/taboo thoughts rather than contamination. While no significant associations with psychotic features (e.g. decreased insight) were observed, TO patients displayed increased suicidality, overall younger age and a significantly larger disparity between seeking treatment and OCD diagnosis. This demonstrates that further clinical awareness and research into TO as an OCD symptom is most needed.

Moving toward a metacognitive conceptualization of cyberchondria: Examining the contribution of metacognitive beliefs, beliefs about rituals, and stop signals

Cyberchondria refers to the repeated use of the Internet to search for health information that leads to negative consequences. The present set of studies examined the tenability of a proposed metacognitive conceptualization of cyberchondria that includes metacognitive beliefs about health-related thoughts, beliefs about rituals, and stop signals. The contribution of those variables to cyberchondria was examined among 330 undergraduate students from a U.S. university in Study 1 and 331 U.S. community respondents in Study 2. All participants reported using the Internet to search for health information. Across both studies, metacognitive beliefs, beliefs about rituals, and stop signals shared positive bivariate associations with cyberchondria and accounted for unique variance in cyberchondria scores in multivariate analyses. Beliefs about rituals and stop signals emerged as relatively specific to cyberchondria versus health anxiety in multivariate analyses. Results provide preliminary support for a metacognitive conceptualization of cyberchondria, with extensions of the present findings discussed.

Reading Self-Concept and Reading Anxiety in Second Grade Children: The Roles of Word Reading, Emergent Literacy Skills, Working Memory and Gender

Background: Most studies in the field of reading have focused on the linguistic and cognitive factors. Less is known about the affective aspects of reading in young readers, such as self-perceptions of reading, and reading anxiety. Aims: This study aimed to shed light on the direct and indirect relations between reading and related skills (working memory, emergent literacy skills, word reading accuracy and rate, and gender) as sources of reading affect (reading self-concept and anxiety). Sample: A total of 115 Hebrew speaking second graders participated in this study. Methods: A set of measures assessing reading accuracy and rate, emergent literacy skills (phonological fluency, rapid automatized naming and working memory) and reading affect questionnaires (reading self-concept and reading anxiety) were administered to the participants. Results: Path analysis was used as the primary analytic approach. Results indicated a negative moderate relation between reading self-concept and reading anxiety. The relations of working memory and emergent literacy to reading self-concept and reading anxiety were indirect via word reading accuracy and reading rate. Girls reported higher reading anxiety and lower reading self-concept, despite higher performance in reading accuracy and no difference in reading rate. Conclusion: The current results support the importance of examining reading affect and potential sources of reading affect. Results suggest that reading self-concept and reading anxiety and their related skills should be considered in designing reading intervention and instructions.
