Background and aims 
Anxiety, depression, catastrophizing and kinesiophobia are associated with reduced treatment efficacy in patients with chronic pain. It is therefore important to screen patients with chronic pain on the presence of these influencing factors before initiating pain treatment using validated questionnaires (the Hospital Anxiety and Depression Scale (HADS), the Pain Catastrophizing Scale (PCS), and the Tampa Scale of Kinesiophobia (TSK)). The aim of this study was to present normative data on anxiety, depression, catastrophizing and kinesiophobia of a chronic pain population in a tertiary hospital.

Methods 
Between May and November 2018, the scores of 370 patients with chronic pain referred to the University Medical Centre Utrecht were collected for analysis. 

Results 
The study population with a mean age of 56 years (SD 16) included 155 men (42%). Overall, 41% scored above the cutoff value for anxiety, 49% for depression, 33% for catastrophizing, and 50% for kinesiophobia; 50% of patients scored above the cutoff value for two or more of these dimensions. 

Conclusions 
Prevalence of anxiety, depression, catastrophizing and kinesiophobia in chronic patients in a tertiary center are high when using the available cutoff values. Half of the patients scored above the cutoff value for two or more of these dimensions. Future research should focus on the implications of multiple high scores on psychometric questionnaires and assess which treatment regimens are most effective in these patients.
