Work and Social Adjustment Scale WSAS
Work and Social Adjustment Scale WSAS overview
Creator and Context
The Work and Social Adjustment Scale (WSAS) is a five item measure of functional impairment attributable to a person's presenting problem.
It was published by Mundt, Marks, Shear and Greist in the British Journal of Psychiatry in 2002, building on earlier work by Isaac Marks. It is the standard functional impairment measure in NHS Talking Therapies, used alongside the PHQ-9 and GAD-7.
Presenting Conditions
The WSAS asks how much the person's problem impairs five areas of life:
Ability to work
Home management
Social leisure activities
Private leisure activities
Ability to form and maintain close relationships
It produces a single total score and has no validated subscales.
Administration
Self completed in about two to five minutes, and also validated as clinician administered. The clinician inserts the presenting problem into the question stem, so the measure is anchored to that specific problem. Each item is rated from 0 (not at all impaired) to 8 (very severely impaired). Item 1 has a tick box for people who are retired or not working for reasons unrelated to their problem.
Desired Audience
Adults with mental health problems, in primary care and psychological therapy services.
Symptom scores tell you how someone feels. The WSAS tells you what it is costing them. Two people with the same PHQ-9 score can have completely different levels of impairment, and the WSAS is a five item way of finding that out.
Considerations
The interpretive bands were derived in OCD and depression samples only. The authors themselves note that whether the pattern generalises to other disorders remains to be tested.
The measure is problem anchored, so scores are not directly comparable across different presenting problems without care.
Item 1 is not applicable to everyone.
There is no explicit recall window, which can cause inconsistent interpretation across time points.
How to score the Work and Social Adjustment Scale WSAS
Conducting the assessment
The person rates five items on a 0 to 8 impairment scale, each in relation to the named presenting problem.
Interpretation
Items are summed to give a total from 0 to 40, where lower is better.
From Mundt et al. (2002):
A score above 20 appears to suggest moderately severe or worse psychopathology.
Scores between 10 and 20 are associated with significant functional impairment but less severe clinical symptomatology.
Scores below 10 appear to be associated with subclinical populations.
The authors add that whether this pattern generalises beyond OCD and depression remains to be tested.
Clinical Considerations
Always name the presenting problem explicitly and keep it consistent across administrations.
Read the WSAS next to the symptom measure. A falling PHQ-9 with a static WSAS usually means the person feels better but their life has not changed yet.
Look at the item pattern. Impairment concentrated in relationships means something different from impairment concentrated in work.
