Background: A measure of perceived health risks of physical activity (PA) among diabetes isneeded for examining its effects on PA participation. This study developed and validated thePhysical Activity Risk Perception Scale for Diabetics (PARPSD). Methods: Chinese diabeticpatients (N=183; Mean age=62.23[SD=14.69]; 63% being women) completed the 25-itemPARPSD and measures of PA self-efficacy, outcome expectations, barriers, and PA participation.The PARPSD was administered again after two weeks (sub-sample: N=48). Findings: A principal-axis factor analysis with promax rotation yielded three factors including symptoms, injuries,and complications, with satisfactory internal consistency (α=.82-.87) and moderate temporalstability (r=.45-.75). Beyond the psychosocial constructs, PARPSD factors explained 5% (p
