Abstract

Background: Food allergy (FA) is a growing condition among children and it's psychological impact over the patients and their caregivers is well known, establishing a vicious circle that perpetuates stress levels. However, psychosocial factors are not commonly included in allergy treatments. Based on the lack of evidence of records about a scale that indicates the level of interaction between biopsychosocial factors in the patient-caregivers dyad for FA, the present research aims to develop a scale with these characteristics as a helpful tool to achieve a more comprehensive system of health care. Methods: A preliminary 28-item scale was generated (sample N = 99). The scale was adjusted in contents and language after expert opinion and application on patients. A factor analysis was carried out selecting the items from the final scale. Results: The final 9-item scale included three areas: impact on quality of life, social impact and conflicts. The scale had a good internal consistency (Cronbach's α = 0.870) and correlated significantly with anxiety and depression measurements. Moreover, it was able to discriminate between study groups (members and non-members of peer support groups) and proved construct validity. Conclusions: The SPS-FA is the first scale for the assessment of the interaction of biopsychosocial factors on FA that includes the patient-caregiver dyad. Its application might be relevant for future research, and it can provide the clinician and the researcher with a solid tool to define which type of psychosocial support is required to provide a more comprehensive care in FA.
