Using the Beck Depression Inventory to Predict Depression
in Patients with Chronic Pain
By Sean Dadswell
June 2007
Aims
To understand the prevalence and possible mechanisms for depression in patients that suffer from chronic pain
To understand how to use the Beck Depression Inventory (BDI) and its reliability and validity
To have knowledge of the literature surrounding the BDI
Contents Introduction to chronic pain and depression
Prevalence of chronic pain and depression
Why choose the BDI
BDI introduction and use
Literature regarding validity, reliability and comparison to other outcome measures
Chronic Pain and DepressionIs it important and why are they together? The more physical symptoms present the more likely depression will
develop (Gatchel 2004) Proposes 3 mechanisms
– Coinciding anatomy of nocioceptive and affective pathways
– Norepinephrine and serotonin implicated in chronic pain and depression mechanisms
– Social factors
Social Factors
(ADLs, Work,
Relationships)
Pain
Depression

Sensitisation

Chronic Pain and Depression Continued.
If both pain and depression are present then both need to be addressed or
treatment will be less effective
(Gatchel 2004)
Chronic Pain and Depression Continued.
Henningsen et al 2003: Large meta-analysis concluded depression more likely with chronic pain of unknown origin than known origin or normal population.
Emptage et al 2005: Huge study interviewing 9,825 individuals found people with pain and depression have significant more limitations with:
– ADL’s– Employment– Recurring Depression– Increasing limitations
Than those with pain or depression alone.
Pain of Unknown
origin
Pain of Known Origin
Normal Population

DEPRESSION
Prevalence Ohayon and Schatzber (2003):
Telephone interviews of 18,980 subjects across Europe
Investigated Depressive symptoms and Chronic pain
Results:– 4% General population had Major
depression– 40% of these had Chronic pain– 10.2% of all Chronic pain subjects had
Major Depression– Subjects with Major Depression 5x
more likely to suffer LBP– 16% General population had mild
depression– 25% of these had related chronic pain
problem
What makes a good outcome and why BDI? CSP Guidelines
(Hammond 2002) Outcome measures for people with depression:
– Assessment of pt change– Assessment of intervention
effect– Help pt’s monitor progress– Help assess service delivery
IMMPACT Guidelines (Dworkin et al 2005) Initiative on Methods Measurements and Pain Assessment in Clinical Trails
– Appropriate– Valid– Reliable– Responsive– Administrable
BDI recommended by both organisations
Beck Depression Inventory Designed 1961 by Beck et al Tool to assess for presence of depression Revisited 1971 and copyrighted 1978 Short form designed 1972 BDI II redesigned 1996 BDI I and II are 21 item Questionnaires Measures attitudes and symptoms depression Rated 0-3 on agreement with statement
i.e. Mood range:
0 = I do not feel sad
3 = I am so sad and unhappy I can’t stand it
(for a patient’s feeling in last week) Implemented in 10 minutes
BDI continued.
Original designed around DSM criteria (Diagnostic and Statistical Manual of Mental Disorders)
Both are scored out of 63 Outcome ranging for no to severe depression
BDI I
Score
Depression Severity
BDI II
Score
5-9 None 0-13
10-18 Mild 14-19
19-29 Moderate 20-28
30-63 Severe 29-63
Figure 3: BDI scores v’s Severity of depression
Not intended to be used as a sole diagnostic tool but to indicate further investigations.
BDI continued.
Original BDI By Beck et al (1961) Study of 226 and 183 subjects (replicated) Psychiatric in and out pt’s Psychiatric diagnosis v’s BDI score Valid (P=0.001) Reliable (coefficient 0.93) Low test re-test reliability (Memory and condition
fluctuation) Sensitive to change
BDI II Introduced 1996 to comply with changes to DSM IV Word and item changes Increased time scale (Pt’s symptoms 2 weeks)
Beck et al 1996 BDI I v’s BDI II Sample 140 in and out pt’s Randomisation not appropriate All subjects completed BDI I and II Results: High correlation between BDI I and II (p=0.001) Mean score BDI II>BDI I
BDI II continued.
Beck et al (1996) Limited as author involved in BDI invention
Dozois et al (1998) Statistical and factor analysis of 1022 students Good paper which has been heavily cited
Results:– High internal consistency between BDI I and II (P=0.001)– Recommended altered cut-offs– Validity confirmed by factor analysis– Reduced sensitivity secondary to time increase
Factor Analysis
Extensive research for BDI and factor analysis
Reduce number of variables Detects structure or relationships between
variable Each group called factor Types of factors relates to validity Implemented by exploratory and confirmatory
factor analysis
Literature Relating to Factor Analysis
Morley et al (2002) and Poole et al (2006) only papers related specifically to BDI and Chronic pain
Archival random samples 1942 and 1227 subjects respectively
Statistical methodology consistent with all factor analysis papers
2 Resultant factors:Cognitive-AffectiveSomatic
Conclusion: High validity for use of BDI II to screen patients with chronic pain for the presence of
depression
Literature Relating to Factor Analysis Continued.
Dozois et al (1998) Agrees with these findings Student population
Ward (2006) Feels 1 general factor more appropriate Does admit that it my only be AS effective as 2 factor
solution Extremely complex paper difficult to appraise for non-
statistician
How Does BDI Compare to Other Outcome Measures?Limited comparison for Chronic Pain Subjects
Geisser et al (1997) compared BDI to Epidemialogical studies depression scale
Positives Negatives
Relevant sample reasonable size (132)
Old
Excellent Lit review 3:1 women:men ratio
Blinded
Good methodology
Conclusion: Both equally valid in the prediction of depression in pt’s with
chronic pain
How Does BDI Compare to Other Outcome Measures? Continued.
Svanberg and Asberg (2001)
Compared BDI to Montgomgery Asberg Depression Rating Scale
Positives Negatives
Good methodology Small Sample (49)
Sample only Psychiatric pt’s with sever problems
Author involved in outcome design
Conclusion: Minimal difference in both measures although results of little use
How Does BDI Compare to Other Outcome Measures? Continued.
Aben et al (2002)
Compared BDI to Hospital Anxiety and Depression scale, SCL-90 and Hamilton Depression Scale
Positive Negative
Good sample size 202 Poor sample relevance
Control/comparison group to DSM IV diagnosis
Statistics for normal values and adjusted for optimal values
Conclusion: All outcomes are equally valid for screening for depression
Conclusion It is important to consider the effects of Depression
when treating patients with Chronic Pain
The BDI I and II are valid and reliable instruments in detecting the presence of Depression in patients with Chronic Pain
BDI is as effective as other outcome measures in the detection of Depression in Chronic Pain patients (limited evidence)
BDI should not be used as a sole diagnostic tool
Ideas for Future Development
More recent research aimed at BDI in Chronic Pain Samples
Specifically comparisons to other outcomes
