Waste separation behavior, environmental factors, and normative beliefs significantly influenced the behavioral intention score for waste separation (p<0.0001). The levels of increase for the aforementioned factors were reported as 0.655, 0.101, and 0.204, respectively (R²=0.569). Additionally, the history of waste separation training (p<0.0001) and the spouses’ educational level (p=0.003) were found to significantly affect the behavioral intention score for waste separation, with levels of increase reported as 0.786 and 0.275, respectively (R²=0.203).</span></span></span></span></span><br> <span style=font-size:11pt><span style=line-height:normal><span style=font-family:Calibri,sans-serif><b><span lang=EN style=font-size:10.0pt><span style=font-family:Cambria,serif><span style=color:#4f81bd>Conclusion:</span></span></span></b> <span style=font-size:10.0pt><span style=font-family:Cambria,serif>The housewives’ behavior and their behavioral intention regarding waste separation largely depend on the history of waste separation training at the source and on environmental factors</span></span><span lang=EN style=font-size:10.0pt><span style=font-family:Cambria,serif>. <b><span style=color:#4f81bd></span></b></span></span></span></span></span><br> Behavior,Waste Management,Intention, 721 726 http://hehp.modares.ac.ir/browse.php?a_code=A-10-22290-6&slc_lang=en&sid=4 Z.S.
