This study aimed to identify the optimal self-report tool for population surveillance of SB, using a systematic framework.<h4>Design</h4>A framework, TAxonomy of Self-reported Sedentary behaviour Tools (TASST), consisting of four domains (type of assessment, recall period, temporal unit and assessment period), was developed based on a systematic inventory of existing tools. The inventory was achieved through a systematic review of studies reporting SB and tracing back to the original description. A systematic review of the accuracy and sensitivity to change of these tools was then mapped against TASST domains.<h4>Data sources</h4>Systematic searchBMJ openTAxonomy of Self-reported Sedentary behaviour Tools (TASST) framework for development, comparison and evaluation of self-report tools: content analysis and systematic review.PMC5775464MR/K025023/1MR/K00414X/1Seniors USP: Understanding Sedentary Patterns MR/KCoulter EHFitzsimons CFChastin SStarr JLaird KMutrie NSattar NGill JShaw RGreig CDeary IHindle EWyke SMead GPalmer VCukic IGranat MRadakovic RGale CStewart SSkelton DASeniors USP TeamDall PMDontje MDer GGray CCox SfalseTAxonomy of Self-reported Sedentary behaviour Tools (TASST) framework for development, comparison and evaluation of self-report tools: content analysis and systematic review.<h4>Objective</h4>Sedentary behaviour (SB) has distinct deleterious health outcomes, yet there is no consensus on best practice for measurement.
