score as a point of departure. To use the Brief IPQ-DLV as starting point might help clinicians to overcome the difficulty they experience in applying biopsychosocial and person-centred approaches 19.
Overall, the conclusions that can be drawn from the first theme of this thesis are:
• The Brief IPQ-DLV is available for use in daily practice as a questionnaire for the first step in exploring IPs. A further exploration is recommended by conducting in depth interviews of the IPs with the respondents, especially those who are indicative for dysfunctional IPS
• Further research is needed to address the psychometric properties content validity and
responsiveness.

Research question:
What are the associations of Illness Perceptions with pain intensity and physical functioning in patients with musculoskeletal pain? A systematic review of literature.
Summary of main findings
From the literature review we concluded that there is limited to moderate evidence for a cross-sectional association of IPs with pain and physical functioning for various MSP condi- tions. The prognostic value in longitudinal studies remains unclear due to the lack of such studies. Further, the findings show a consistent direction of the association among twelve different musculoskeletal conditions, meaning patients with higher scores on IPs dimensions (indicative for dysfunctional IPs) experience more pain and limitations in physical functioning, independent of the nature of the condition. For future research, we advise to investigate the longitudinal relationship between IP domains and outcome in more detail. In addition, stud- ies on the impact on pain and physical functioning of incorporating IPs in interventions for the management of musculoskeletal pain are recommended.
Discussion
A meta-analysis shows that the CSM has been researched extensively in a large number of diseases and illnesses such as cardiovascular disease, diabetes, cancers, arthritis, forms of chronic pain, chronic obstructive pulmonary disease, end-stage renal disease, chronic fa-
