Clinical
Method of
Delivery: Self-administered questionnaire.
Description:
The IBQ assesses maladaptive responses to illness,
hypochondriacally responses, denial, and changes in affect. The
test is self-administered that uses a yes/no response format. The
IBQ is introduced to the patient as a survey containing “a
number of questions about your illness and how it affects you”.
These 62 questions are grouped into seven dimensions identified
empirically via factor analysis.
Scoring/Interpretation:
From the seven dimensions: General Hypochondriasis – A
high score suggests an element of interpersonal alienation
secondary to the patient’s phobic concern. Disease
Conviction – Affirmation that physical disease exists with
symptom preoccupation.

Validity
(Quantitative): Pilowsky reposted evidence for the validity of
the 10 questions on hypochondriasis. The score (based on 118
patients) were compared with their spouses’ perceptions of
what the patients’ responses would have been. A correlation
of 0.65 was obtained. For the 62 item version, evidence for
convergent and divergent validity was obtained from correlations
with the Center for Epidemiologic Studies depression scale
(CES-D). High Pearson correlations for effective disturbance were
0.55, 0.50 for disease conviction, and 0.47 for hypochondriasis.
Reliability
(Quantitative): Test-retest correlations for the seven scales
reported for 42 cases range from 0.67 to 0.87 (after 1 to 12
weeks), with only three coefficients below 0.84. The ten
hypochondriasis items showed a test-retest correlation of 0.81
(N=71). Coefficient theta internal consistency for all scales
ranged from 0.36 to 0.72 with an overall alpha of 0.62.
