Abstract Introduction It has been suggested that sleep continuity disturbance and/or short duration is associated with increased impulsivity across clinical populations (i.e., The Mind After Midnight Theory). Consistent this theory are the findings showing binge eating (BE; a subjective sense of loss control over one’s eating) both cross-sectionally and longitudinally. To date, no study examined whether mediates association between BE. Further, extant literature relied on retrospective self-report assessment which subject to recall social desirability biases. aim present was examine performance behavioral measure (Go/No-Go task) mediated quality (SQ), efficiency (SE%), daytime dysfunction (DD), as measured by PSQI, BE frequency. Methods parent sample 63 individuals (85.9% female; X̅age=40.6 years) seeking treatment for Of note, extremely low levels were excluded from study. Mediation models using lavaan package in R (version 4.1.3) effect DD association.". current analyses included full available all co-varied depressive symptoms. Results A negative direct observed (B=-55.43, S.E.=22.06, p=.01) did not significantly mediate SQ (B=0.20, S.E.=0.59, p=0.73), SE (B=-0.02, S.E.= 0.14, p=0.92), or (B= 0.160, S.E.=1.14, p=0.51) Conclusion While our sample, may have under-powered detect even large effects due its moderate size insomnia Future studies should evaluate these associations samples, prospective measures do so samples insomnia. such take into account time day considerations.
