Although numerous epidemiological studies have investigated LBP, heterogeneity in pain definitions and assessment indicators has limited comparability across studies. A brief and reproducible questionnaire incorporating core LBP indicators commonly used in pain epidemiology may facilitate consistent assessment of LBP occurrence and impact in population\u2010based research.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We proposed a brief low back pain questionnaire (B\u2010LBPQ) designed to assess the occurrence and characteristics of LBP in epidemiological studies. The B\u2010LBPQ consists of seven items covering current LBP, LBP during the past 12\u2009months, lifetime experience of LBP, pain duration, and pain\u2010related interference with daily activities. A cross\u2010sectional validation study was conducted among 783 Japanese welfare workers aged 20\u201374\u2009years (mean age: 41.9\u2009years) undergoing routine health checkups. Construct validity was examined by comparing questionnaire\u2010based LBP classifications with scores on the Roland\u2013Morris Disability Questionnaire (RDQ). Internal consistency was assessed using Cronbach\u2019s alpha. Test\u2013retest reliability over a 2\u2010week interval was evaluated among 595 participants using kappa statistics, prevalence\u2010adjusted bias\u2010adjusted kappa (PABAK), and weighted kappa coefficients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Construct validity was supported by significantly higher RDQ scores among participants reporting LBP compared with those without LBP (all\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
