Direct, total, and mediated effects of sleep quality and physical activity on learning goal achievement via positive and negative affect on a within-person level.

Note. Ratios are based on absolute values of direct and indirect effects, e.g. positive affect mediated 41% of the total effect between sleep quality and learning goal achievement. a = path from predictor to mediator; b = path from mediator to outcome;B = unstandardized regression coefficient; c = ab (indirect effect) + c’ (direct effect); c’ = path from predictor to outcome after controlling for the mediator; SE = standard error.Direct, total, and mediated effects of sleep quality and physical activity on learning goal achievement via positive and negative affect on a within-person level.
