Wenn man sich selbst einfach nicht „riechen” kann

Abstract

Olfactory Reference Disorder is a little explored and widely unknown phenomenon, even research has shown more interest in it during the last years. This review summarizes the existing literature and illustrates its findings with a case history. The databases PubMed, PsychNet, PsychPub, Hogrefe EContent and the Cochrane Library (CENTRAL) were searched for keywords. The identified literature shows that there is a big lack of well-designed studies concerning ORS, in all areas of its nosology. The suffering of persons with ORS, however, is really incriminating.

Prevalence of olfactory reference disorder according to the ICD-11 in a German university student sample

“…Using the ICD-11 CDDR of ORD, we determined a prevalence of 5.5% in our sample. Our findings are consistent with the findings of Schmidt et al (2017) who suggested that ORD is relatively common in non-clinical settings. Indeed, according to our estimated prevalence of 5.5%, ORD might be more prevalent than other mental disorders in university / college students.…”

“…This is the first study exploring the prevalence of ORD measured in accordance with the newly formalized ICD-11 required features, assessed in a non-clinical German university student sample. There are only a few previous studies, which, in the absence of standardized diagnostic categorization, captured the disorder, albeit with different criteria, that reported prevalence rates of 2.1% in a sample of Japanese university students (Kasahara & Kenji, 1971), 2.4% in a sample of Chinese university students (Zhou et al, 2018) and 6.4% in a sample representative of the German general population (Schmidt et al, 2017). Using the ICD-11 CDDR of ORD, we determined a prevalence of 5.5% in our sample.…”

“…There is a lack of basic knowledge about the disorder, including its prevalence which is currently unclear. To the best of our knowledge, only four studies have estimated the prevalence of ORD (Kasahara & Kenji, 1971;Schmidt et al, 2017;Zhou et al, 2018). These studies indicate that ORD might be comparatively common, however, due to a lack of standardized diagnostic criteria, the ORD diagnoses were assessed with different criteria.…”

“…Zhou et al (2018) used a total score of ≥ 20 on the ORS-YBOCS to determine ORD. In their review, Schmidt et al (2017) reported that they had found prevalence rates of 5.2-6.4% in two unpublished pilot studies based on a German sample representative of the general population using the ORS-Y-BOCS. To determine ORD, the scale distress was dichotomized into the two groups "clinically significant" vs. "clinically not significant".…”

Ekel und die olfaktorische Referenzstörung

“…Personen mit ORS berichten bezüglich ihres Körper-geruches von Ekel und Abneigung [Schmidt et al, 2017]. Aus bisherigen Untersuchungen geht hervor, dass 95-100% der von ORS Betroffenen mindestens eine Sicherheitsverhaltensweise zeigen, um sich dieses Geruchs zu entledigen bzw.…”
