Development of the scale of psychosocial factors in food allergy (SPS-FA)
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 a = 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.
