This study aims to review the six steps in quality intervention development (6SQuID) framework by focusing on its application for reducing sedentary behavior among employees.<br> <strong>Materials & Methods</strong>: This descriptive review was undertaken through a critical and integrative examination of the 6SQuID framework, with particular attention to its conceptual foundations, procedural stages, and methodological robustness as a comprehensive framework for the systematic development of interventions.<br> <strong>Results</strong>: The six steps in developing an intervention are as follows: 1) define and understand the problem and its underlying causes within the target group; 2) identify modifiable contextual or causal factors with the greatest potential for change; 3) identify the mechanisms to bring about change; 4) identify the most appropriate strategies to deliver these change mechanisms; 5) pilot the intervention on a small scale and refine it; and 6) collect robust evidence of the intervention&rsquo;s effectiveness to conduct rigorous evaluation for large-scale implementation. This model has been applied in the development of the &ldquo;stand up for health&rdquo; intervention to reduce sedentary behaviors among employees of contact centers in the United Kingdom.<br> <strong>Conclusion</strong>: Given the effectiveness of the 6SQuID model, researchers and policymakers in Iran are encouraged to adopt this framework for the systematic and successful development of educational and clinical interventions.&nbsp;<br> &nbsp;</div> Clinical interventions, Intervention study, Six steps in quality intervention development (6SQuID), Step-by-step strategy 221 232 http://cpr.mazums.ac.ir/browse.php?a_code=A-10-256-1&slc_lang=en&sid=1 Fateme Jafarpoor fateme_jafarpoor@yahoo.com 10031947532846002554 10031947532846002554 Yes Department of Psychology, Faculty of Education & Psychology, Shahid Beheshti University, Tehran, Iran.
