Abstract
Objectives
The present study explored affective touch in anorexia nervosa (AN) by: (a) comparing patients with AN and healthy control subjects (HCs) on the quality and quantity of affective-touch experiences across the lifespan; (b) investigating the association between affective touch and body-image-related symptoms; (c) assessing the link between affective touch and interpersonal space (IPS).
Methods
Participants (76 patients with AN and 77 HCs) completed self-report questionnaires measuring eating-related symptoms, anxiety, depression, and affective-touch experiences. IPS was assessed with a computer-based stop-distance task with different social conditions.
Results
Patients with AN had higher general (i.e., anxiety and depression), and body-image-related (e.g., body checking, body dissatisfaction) symptoms than HCs; moreover, they reported lower quantity of affective touch both in childhood and adulthood and less comfort with affective touch, with a medium to large effect size; more frequent negative affective-touch experiences were also observed in patients than in HCs, with a medium effect size. In patients, lower experienced affective touch, both in childhood and adulthood, and reduced touch-related comfort were associated with larger IPS, independent of anxiety and depression, and with a high effect size after statistical adjustment. No associations with IPS emerged in HCs.
Conclusions
The results highlighted a link between negative and reduced affective touch and social difficulties and avoidance in AN. The study remarks the relevance of affective-touch experiences and their relation with implicit body-related mechanisms, suggesting addressing early tactile experiences and interpersonal functioning in clinical interventions.
Level of evidence
Level III, case–control study based on self-report questionnaires and a behavioral task.
