Mediation analysis with SAS scores as the predictor, daily interruptions (defined as the number of work hours lost to smartphone use) as the mediator, and the self-reported negative impact of smartphone use on work productivity as the dependent variable. a = path a; b = path b; c = total effect, i.e. SAS scores on productivity, mediated by daily interruptions; c’ = direct effect of SAS scores on productivity; b = unstandardized regression coefficients.
