The perceived level of psychological work demands evidenced a nonsignificant trend to be a moderator (B = −0.73, SE = 0.11, R 2 = 0.38, P = 0.051) for the active break vs control group and active break vs postural shift group (B = −1.69, SE = 0.14, R 2 = 0.22, P = 0.241) with respect to the development of neck pain.
