Table 5 (models 3 and 4) also attest to the lack of mediating effects because the potential mediators do not impact
quality capability (model 3: b = _0.04; model 4: b = _0.14, ns) and thus the indirect effects are nonsignificant (model 3: t = _0.33; model 4: t = _0.82 respectively). H2b and H2c are consequently rejected.
