The Nordic Musculoskeletal Questionnaire (NMQ) quantifies musculoskeletal pain and activity prevention in 9 body regions. The purpose of this study was to develop an extended NMQ (NMQ-E) to collect greater information regarding musculoskeletal pain, examine test–retest reliability and the reproducibility of alternate administration methods. Reliability was examined using observed proportion of agreement for all (Po), positive (Ppos) and negative (Pneg) responses, kappa
(k), proportion of maximum kappa achieved (k/kmax), intra-class correlation coefficient (ICC) and standard error of measurement (SEM). The NMQ-E was self-administered by 59 Bachelor of Nursing students at a 24-h interval with mean Po = 0.88–0.98 and k/kmax = 0.71–0.96 for 10 dichotomous questions and mean ICC(2,1) = 0.97 and SEM = 1.05 years for the age at symptom onset question. The NMQE
was completed via self and interview administration by 31 student nurses at a 0.97 ± 1.14 day
interval with mean Po = 0.92–0.98 and k/kmax = 0.76–1.00 for binary questions and mean ICC(2,1) =
0.90 and SEM = 1.51 years for age at symptom onset data. In both sub-studies, mean Ppos was lower
than mean Pneg and low prevalence reduced k in many instances. The NMQ-E collects reliable information
regarding the onset, prevalence, and consequences of musculoskeletal pain and can be
administered by self-completion and personal interview. Perspective: This study presents an NMQ-E that collects reliable information regarding the onset,
prevalence, and consequences of musculoskeletal pain in 9 body regions. The NMQ-E can be utilized
in descriptive studies or longitudinal studies of disease outcome and can be administered via selfcompletion
and personal interview
