However, increasing sedentary lifestyles, suboptimal dietary patterns, and weight-related body image concerns contribute to the growing burden of obesity in this age group. A comprehensive and culturally sensitive assessment tool is needed to capture these multidimensional factors. This study aimed to develop and psychometrically validate a questionnaire assessing lifestyle behaviours, weight-related body image concerns, and past weight management strategies among young adults (YAs).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      A mixed-method design was employed.
