In this issue of the Scandinavian Journal of Pain (SJP) Whibley and colleagues report on how the relationship between neck and distal upper limb pain and disability is moderated by pain beliefs [1].

1 Persistent pain is the dominating cause of work disability

Persistent pain is severely disabling. The SJP has previously published data from two independent studies showing that around 50% of the work disability is attributable to persistent pain [2, 3]. The costs for society are immense, making this a public health issue of utmost importance.

2 Individual specific factors contribute to wide variation in pain from the same disease or injury

Prevention and treatment of persistent pain has traditionally focused on diagnosing and treating the peripheral pathology causing pain. Thus if the patient suffers from pain from osteoarthritis of the hip, hip arthroplasty may be indicated. Unfortunately this approach fails in very many cases. This is firstly, because there appears to be poor correlation between the degree of peripheral pathology and the degree of pain, and secondly, because the peripheral pathology is frequently not known [4]. Though these findings may in part be explained by inadequate diagnostic techniques, for instance that we lack imaging techniques for detecting pathology in soft tissues, there is substantial evidence suggesting that individual specific factors such as pain sensitivity contribute to the variation in pain among people suffering from the same disease or injury.

3 Socio-economic and psychological factors may increase risk of disability from pain

Just as the relationship between pathology and pain is tenuous, so is the relationship between pain and disability. While some patients function relatively well with moderate to strong pain, others become severely disabled. Some factors moderating the association between pain and disability have been identified. For instance, there is evidence that fibromyalgia patients with low socio-economic status experience greater functional impairment than high socio-economic status patients with similar levels of pain, depression and anxiety [5]. There is also evidence that a number of psychological factors including self-efficacy, psychological distress and fear of movement may affect the consequences of pain on functioning [6, 7]. Identifying these factors is of great importance for designing effective treatment strategies.

4 Pessimism about prognosis is associated with increased disability among individuals with mild or moderately strong pain

Whibley and coworkers approach this issue in a sample of 476 patients with arm pain [1]. They first performed exploratory factor analysis of a health beliefs questionnaire, identifying five constructs. Moderation analysis was then carried out to determine which of these constructs moderated the association between pain and disability. A moderation effect was found for beliefs about prognosis, with greater pessimism about prognosis being associated with greater disability among those with mild to moderate pain.

As the authors point out, the analysis is cross-sectional and the results should be interpreted with some caution. For instance, though it may be that pessimism leads to greater disability among patients with mild to moderate pain, it is also possible that patients become more pessimistic when experiencing greater disability. Perhaps the most noteworthy finding is the absence of effect for the other four pain belief constructs. For instance it is commonly found that fear of movement can contribute towards a poor outcome [6], yet this appears not to be the case in this study [1].
