Correlation and agreement analysis.
The objective of this study was to compare the Brazilian Portuguese versions of the Örebro Musculoskeletal Pain Screening Questionnaire Short-Form (ÖMPSQ-short) and the STarT Back Screening Tool (SBST)-Brazil in patients with low back pain and to verify their correlation with disability, kinesiophobia, and pain.
The ÖMPSQ-short and the SBST were designed to identify patients at risk of developing pain and disability related to psychosocial factors.
We assessed 130 patients, who answered the ÖMPSQ-short, SBST-Brazil, Roland-Morris disability questionnaire, Tampa scale of kinesiophobia, and Pain Numerical Rating scale. The total scores of the ÖMPSQ-short and the SBST-Brazil were correlated with the other questionnaires. Cross-tabulation and Cohen κ were used to analyze the agreement between the ÖMPSQ-short and the SBST-Brazil for participant classification as low or high risk for involvement of psychosocial factors.
The ÖMPSQ-short and the SBST-Brazil presented good correlation between total scores (r = 0.73), good correlation with disability (ÖMPSQ-short: r = 0.72; SBST-Brazil: r = 0.76), and kinesiophobia (ÖMPSQ-short: r = 0.68; SBST-Brazil: r = 0.60) and moderate correlation with pain in the last episode (ÖMPSQ-short: r = 0.39; SBST-Brazil: r = 0.48), in last 2 weeks (ÖMPSQ-short: r = 0.39; SBST: r = 0.43), and current pain (ÖMPSQ-short: r = 0.39; SBST-Brazil: r = 0.31). Participant classification as high or low risk by the two questionnaires showed moderate agreement (κ = 0.49). A total of 83% of participants were classified correctly by the two questionnaires.
The ÖMPSQ-short and the SBST-Brazil showed good correlation between total scores and moderate agreement for patient classification in relation to the presence of psychosocial factors.
