WLQ indicates Work Limitations Questionnaire.
Note: Bold font denotes statistical significance. None of the interaction terms were statistically significant and were excluded from the final models.
*
Models were adjusted for baseline age, gender, years on the job, and value of the model’s dependent variable.
†
The coefficients were multiplied by 10.
