Abstract:

The purpose of this paper was to study
the psychometric properties of the Obsessional Beliefs Questionnaire-44 (OBQ-44) in nonclinical
adolescents. Additionally, the factorial structure of obsessive cognitions and its relationship
with obsessive-compulsive symptoms were also analysed. A sample of 508 adolescents was
used, 49% of them being boys. The age range was 12-19, with a mean age of 14.9 (SD= 1.6).
The results indicated that the OBQ-44 has good psychometric properties. The internal consistency
of the subscales ranged from 0.77 to 0.86. Confirmatory factor analyses indicated that both
the three-factor (Responsibility/Threat estimation, Importance/Control of thoughts and
Perfectionism/Certainty) and the four-factor (Importance/Control of thoughts, Responsibility,
Perfectionism/Certainty, and Threat estimation) models showed an adequate fit to the data.
Likewise, a statistically significant correlation was observed between obsessive-compulsive
symptoms and obsessive beliefs. Consistent with previous literature, obsessive cognitions
presented a multifactorial structure and were found to be associated to obsessive-compulsive
symptoms. Hence, the OBQ-44 can be considered an adequate measurement instrument for
the assessment of dysfunctional beliefs in nonclinical populations.
