Examining five pathways on how self-control is associated with emotion regulation and affective well-being in daily life

OBJECTIVE Self-control is positively connected to well-being, but less is known about what, on the mechanistic level, explains this association. We hypothesized five pathways how this connection could be explained by emotion regulation, that is, by facilitating (a) strategy effectiveness, (b), adaptive strategy selection, (c) situation selection, (d) strategy variability, or (e) social sharing. METHOD To explore these pathways, we integrated two ambulatory assessment data sets (N = 250 participants, N = 22,796 observations) that included assessments of participants' emotions and their emotion regulation efforts. RESULTS We found that self-control was positively associated with affective well-being. Moreover, momentary but not trait self-control was associated with favoring adaptive and interpersonal strategy selection and less emotion regulation in general as well as with increased variability across strategies. However, these emotion regulation facets could not sufficiently explain the association between self-control and affective well-being. CONCLUSIONS Our main conclusion is that emotion regulation is not a mediator of the strong relation between self-control and affective well-being. Instead, we found evidence for the affective benefits of employing ways of emotion regulation that are less taxing mentally, which we discuss in light of current knowledge about self-control and emotion regulation.
