Attentional control mediates the relationship between social anhedonia and social impairment.

Bottom Line: However, the mechanisms underlying the relationship between SA and social impairment are poorly understood.Moreover, attentional control mediated the relationship between SA and social impairment, establishing attentional control as one mechanism underlying aberrations in the fundamental human need for social contact.Although both attentional deficits and social impairment have been separately noted in SA, the relationship between SA, attentional control and social impairment in this non-clinical sample reflects a novel contribution.

ABSTRACT
Social anhedonia (SA), a trait-like disinterest in social contact and diminished capacity to experience pleasure from social interactions, is consistently associated with social impairments in both healthy and clinical populations. However, the mechanisms underlying the relationship between SA and social impairment are poorly understood. Attentional control, selecting and focusing on relevant information and inhibiting irrelevant, may be one such mechanism. We examined individual differences in SA, attentional control, and social impairment in 108 healthy adults. High SA related to low attentional control and high social impairment. Moreover, attentional control mediated the relationship between SA and social impairment, establishing attentional control as one mechanism underlying aberrations in the fundamental human need for social contact. Although both attentional deficits and social impairment have been separately noted in SA, the relationship between SA, attentional control and social impairment in this non-clinical sample reflects a novel contribution.

Figure 2: (A) The effect of SA on social impairment through attentional control. (B) The effect of SA on social impairment through the three components of attentional control: focusing, divided, and shifting attention. Unstandardized path coefficients (SE) shown for each path. *p < 0.05; **p < 0.001.

Mentions: We assessed the single mediator model in which attentional control is hypothesized to mediate the relationship between SA and social impairment. All four paths were significant in the predicted directions (Figure 2A): SA had a total positive effect on social impairment (β = 0.90, p < 0.001), and a total negative effect on attentional control (β = -0.42, p < 0.001); attentional control had a direct negative effect on social impairment (β = -0.42, p = 0.001). Bootstrap analysis of the indirect effect (Table 4A) revealed a bias corrected 95% confidence interval excluding zero (CI0.95 = 0.08, 0.33), demonstrating that attentional control mediates the relationship between SA and social impairment. The direct effect of SA on social impairment, controlling for attentional control, remained significant (β = 0.72, p < 0.001), indicating that attentional control only partially mediates the relationship between SA and social impairment. The mediated effect of SA on social impairment through attentional control accounts for 19% of the variance in social impairment (R2med = 0.19, CI0.95 = 0.08, 0.32).
