Adults with I/DD living in group homes and apartment settings have diets high in fat calories and low in fruits and vegetables. Interventions focused on increasing nutrition and physical activity knowledge and reducing obesity require changes in dietary and activity practice. Many of the assessment tools used to assess nutrition knowledge are long and very time consuming to administer. Adults with I/DD may lose concentration and interest during testing, which makes it difficult to obtain reliable and valid data concerning nutrition knowledge. Nutrition and Activity Knowledge Scale (NAKS) is an eighteen-item scale that was developed specifically for adults with I/DD to address these issues and to assess nutrition and physical activity knowledge among adults with I/DD. NAKS was adapted and assessed for reliability. Cronbach's alpha is high for both factors Ą = 0.86 (weight/weight control) and Ą = 0.75 (nutritional value of food). Test-retest reliability for the weight/weight control subscale was r = 0.67 (p<0.001), and for the nutritional value of food subscale was r = 0.39 (p<0.01). We have completed test-retest reliability on NAKS with 24 participants. Our results show high test-retest reliability for the weight/weight control subscale r = 0.84 (p<0.001), nutritional value of food subscale r = 0.69 (p<0.001), and total test-retest reliability was r = 0.82 (p<0.001). Little data exists regarding the outcomes of nutrition and physical activity literacy in this population. NAKS has the potential for use in future studies to evaluate outcomes of physical activity and nutrition education programs for adults with I/DD.
