CuraLinc used the Stanford Presenteeism Scale-6 (SPS-6) to assess the relationship between presenteeism, health problems and productivity for employees who participated in the employee assistance program (EAP). The SPS-6 measures an employee's perception of his or her ability to overcome the distraction of current physical and/or psychological problems in order to handle job stress, complete tasks, achieve goals and maintain sufficient focus and energy levels. The SPS-6 employs a Likert Scale to record responses, ranging from ‘Strongly Disagree’ (1) to ‘Strongly Agree’ (5). The maximum score of the six-question set is 30.
5,223 program participants completed the SPS-6 during the initial assessment, 777 of whom also completed the questionnaire again 30 days post-treatment. From among those who completed the questionnaire after 30 days, the average SPS-6 score increased from 18.8 (moderate productivity) to 24.9 (high productivity), a gain of 6.0, adjusted for rounding.
