Abstract:

The aim of this study was to develop a valid and reliable scale for assessing food and nutritional insecurity specifically in adolescents. The initial version of the scale was composed of two subscales: perception of food insecurity and perception of nutritional security. The items were submitted to content analysis (n = 4) by a group of experts in food and nutrition security and to semantic analysis (n = 20) by a group of adolescents conveniently sampledthe target population. School adolescents (n = 425) aged 12 to 18 years (m = 14.32±0.96; CV = 6.7%) participated in the pilot study. A two-factor model was the most appropriate one. The subscales presented modest values of the alpha coefficient (0,69 and 0,60, respectively). Daily consumption of fruits, vegetables and soft drinks was shown to be significantly associated with higher scores in the scale of perception of food and nutrition security. Therefore, it is recommended to combine items based on food access with other aspects related to attitudes and behaviours towards healthy eating in order to obtain a more credible report of adolescent’s needs and better guide the development of public policies.
