Abstract: Background: Alterations in the experience of controlling oneself and one’senvironment are of high relevance to understanding the psychopathology ofdepression. This study investigated the relationship between Temporal Bindingfor action-event sequences, sense of agency, self-efficacy and symptom severityin Major Depressive Disorder.Method: We employed the Sense of Agency Scale (SoAS) and the General Self-Efficacy Scale (GSE) to assess explicit Sense of Agency and self-efficacy in agroup of 42 persons diagnosed with Major Depressive Disorder (MDD) [20identifying as female, 19 as male; mean age 37.8 years (± 13.3)] and 40 controlpersons without a psychiatric diagnosis (CG) [22 identifying as female, 20 asmale; mean age 38.0 years ( ± 13.3)]. Depressive symptom severity was measuredusing the BDI-II. We additionally performed a temporal binding paradigm as apotential correlate to Sense of Agency. Participants partook in a time estimationtask judging three intervals (250ms, 450ms, 650ms) while either observing orcausing stimulus presentations. The underestimation of intervals followingintentional actions causing stimulus presentations (compared to merelyobserving the stimulus presentation) is interpreted as temporal binding.Results: SoAS scores demonstrated an inverse correlation with depressivesymptoms (CG: p=.032, R2=.113; MDD: p<.001, R2=.260) and a positivecorrelation with GSE scores (CG: p<.001, R2=.379; MDD: p<.001, R2=.254). Wefound distinct differences in temporal binding between healthy participants andthe Major Depressive Disorder group without significant correlation betweentemporal binding and the SoAS or GSE scores. The data suggest groupdifferences in time estimation particular pertaining to time intervals involvingintentional action and increasingly complex multisensory stimuli.
