We performed a comparison of construct convergent and known-group validity and ceiling floor effect (CFE) of these tools using a common sample of patients seen at a tertiary care spine centre. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p> This was a cross-sectional study of patients with and without a work-related back injury. The Hospital Anxiety and Depression Scale (HADS) was used as the reference outcome measure for convergent validity. For known-group validity, we examined the ability of the scales to differentiate between different levels of compensation, presence of non-organic signs, and work status. The CFE values were calculated. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> Fifty consecutive injured workers were included along with 50 patients without an active compensation claim related to their low back pain. STarTBack and OSPRO-YF had moderate to high associations with the depression component of the HADS (0.69 to 0.77 respectively) with a statistically significant difference in favour of the OSPRO-YF. STarTBack's risk stratification categories were able to differentiate patients with a compensable injury, non-organic signs, and inability to work ( p values ranging from 0.002 to &lt; 0.001). The physical activity and work fear-avoidance beliefs constructs of the OSPRO-YF consistently outperformed other yellow flag constructs ( p values ranging from 0.008 to &lt; 0.001). The psychological sub-score of STarTBack showed a ceiling effect. There was a floor effect for the negative affect domain of OSPRO-YF. Neither total score had a floor or ceiling effect. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p> STarTBack and OSPRO-YF are short screening tools with acceptable convergent and known-group construct validity and no floor or ceiling effect of their total score. Both tools could assist with the identification, evaluation, and management of psychological distress in patients presenting to tertiary care spine centres.
