Background Childhood maltreatment (CM) is frequently linked to interpersonal problems such as difficulties in social relationships, loneliness, and isolation. These difficulties might partly stem from troubles regulating comfortable interpersonal distance (CIPD). Objective We experimentally investigated whether CM manifests in larger CIPD and whether all subtypes of CM (i.e., physical, emotional, or sexual abuse and physical or emotional neglect) affect CIPD. Methods Using the stop-distance method (i.e. a team member approached participants until the latter indicated discomfort), we assessed CIPD in 84 adults with a self-reported history of CM (24 with depressive symptoms) and 57 adult controls without a history of CM (without depressive symptoms). Results Adults with CM showed a larger CIPD ( Mdn = 86 cm) than controls ( Mdn = 68 cm), and CIPD was largest for those with CM combined with current depressive symptoms ( Mdn = 145 cm) ( p’s < .047). In the latter group, all subtypes of CM were associated with a larger CIPD compared to controls ( p’s < .045). In the CM group without depressive symptoms, only those with emotional abuse ( p = .040) showed a larger CIPD than controls. Conclusions These results add to findings of differential socio-emotional long-term consequences of CM, depending upon the subtype of CM. Future research should explore whether a larger CIPD has a negative impact on social functioning in individuals exposed to CM, particularly in those with depressive symptoms. HIGHLIGHTS Adults with child maltreatment (CM) prefer larger physical distances. • This effect is more pronounced in those with CM and depressive symptoms. • Troubled regulation of physical distance might contribute to interpersonal problems.
