Further Support for Five Dimensions of Obsessive-Compulsive Symptoms
Five OCD symptom dimensions were revealed that explained 68% and 60% of the variance, respectively, and supported a distinction between the doubt/checking symptom dimension and the unacceptable/taboo thoughts dimension that includes mental rituals.
Symptom structure in Japanese patients with obsessive-compulsive disorder.
The findings in this study support transcultural stability in the symptom structure of OCD, which is consistent with the hypothesis that OCD is mediated by universal psychobiological mechanisms.

Correlates of insight into different symptom dimensions in obsessive-compulsive disorder.
Assessing insight into dimension-specific OCD symptoms may challenge the existence of clear-cut OCD with fair or poor insight.
A comparison of symptom dimensions for obsessive compulsive disorder and obsessive compulsive-related disorders
It is found that OCRD comorbidity does not increase the severity of OCD symptoms and the prevalence of an axis I diagnosis.
Symptom Dimensions in Obsessive-Compulsive Disorder and Obsessive Beliefs
The findings suggest that certain obsessive beliefs predicted certain OCD symptom dimensions, but results are not entirely consistent with the published literature suggesting the possibility of cross-cultural variations.
Are There Familial Patterns of Symptom Dimensions in Obsessive-Compulsive Disorder?
The findings indicate that there is a high concordance of OCD symptom dimensions within multiplex families, andSymptom dimensions of OCD might thus have significant heritability.

It is found that three factors, which are named "symmetry/hoarding," "contamination/cleaning," and "pure obsessions," best explained the symptoms of the Y-BOCS Symptom Checklist.
Symptoms of obsessive-compulsive disorder.
The four symptom dimensions identified in this study are largely congruent with those identified in earlier reports, and may be of value in future genetic, neurobiological, and treatment response studies.

Use of factor analysis to detect potential phenotypes in obsessive-compulsive disorder
Diagnostic interview assessed neuropsychiatric disorder comorbidity in 334 individuals with obsessive–compulsive disorder
Results demonstrate that OCD is highly comorbid with other neuropsychiatric disorders, with 92% of OCD study participants receiving one or more additional Axis I DSM diagnoses.
Prevalence and symptomatology of comorbid obsessive–compulsive disorder among bulimic patients
Obsessive– compulsive symptoms related to symmetry and order were most frequently observed in BN subjects with concurrent OCD, which was a similar finding to that reported among restricting anorexic subjects.

Obsessive-compulsive disorder (OCD) is a complex psychiatric disorder characterized by recurring obsessions or compulsions that cause significant distress to the patient or significantly interfere
Symptom presentation and outcome of cognitive-behavioral therapy for obsessive-compulsive disorder.
Mental compulsions were most prevalent among patients with intrusive, upsetting religious, violent, or sexual thoughts, and response to cognitive-behavioral therapy across symptom categories was compared, finding poorer outcomesamong patients with hoarding symptoms compared with those with other symptom themes.
