Stroke in Working Age and Job Accommodation in Facilitating Transition Back to Work

Absenteeism and presenteeism are evaluated with World Health Organization's Health and Work Performance Questionnaire (HPQ) using both absolute and relative measures. Absolute absenteeism: hours in 4 week (higher value indicates worse outcome). Absolute presenteeism: single question measure of own job performance (score 0-10) analyzed according to the HPQ instructions (higher value indicates better outcome). Relative absenteeism: working hours in 4 week / expected working hours in 4 week. Relative presenteeism: evaluation of own job performance (score 0-10) / evaluation of most other workers job performance (score 0-10). This score is restricted to the range of 0.25 to 2.0 according to HPQ instructions. In both relative scores higher values indicate better outcome.

Estimate of the current work ability measured with single question (score range 0-10, higher score indicate better outcome) from Work Ability Index. Estimate of future work ability measured with single question (categorical variable: yes, no, maybe) from Work Ability Index.

Subjectively evaluated success in returning to work. Single item question with 5 point Likert scale (5= very good; 1= very bad).

Frequency of different cognitive demands at work and related perceived difficulties measured with Brain Work Questionnaire. Frequency values are reported as averaged occurrence/week (lower values indicate better outcome), and related difficulties in ordinal response variable (0=no difficulties, 1=sometimes difficult, 2=often difficult). Higher value indicates worse outcome.

Cognitive symptoms at work measured with The Cognitive Function at Work Questionnaire total score (score range 0-58: higher value indicates worse outcome)

Estimates of perceived stress. General stress measured with single item stress question (score range 1-5, lower value indicates better outcome). Theme specific stress (at home, work and financial). Ordinal 4 point response scales. Questions from INTERSTROKE study.

Number of days on sick leave after returning to work. Higher value indicates worse outcome.

Frequency of insomnia symptoms measured with single item question with ordinal 5 point scale (5=Every night or nearly every night; 1=never). Higher value indicates worse outcome.

Fatigue symptoms measured with Fatigue Assessment Scale (FAS). Total score range 10-50. Higher score indicates worse outcome.

Perceived life satisfaction based on the Young Stroke Questionnaire (total score 0-100; where higher score indicates better outcome)

Perceived mental job strain. Single item question with ordinal 1-5 point response scale (1=not at all; 5 very much). Higher value indicates worse outcome.

Perceived cognitive and emotional difficulties in general measured with Check List for Cognitive and Emotional Consequences. Likert scale questions 0-2. Higher values indicate worse outcome.

The Modified Rankin Scale (mRS) measures degree of disability/dependence after a stroke. The mRS is a 6 point disability scale with possible scores ranging from 0 to 5. Higher score indicates worse outcome.

Perceived benefit of the carried out job accommodations. Single item question with 5 point Likert scale (5=very much; 1=very little). Higher value indicates better outcome.

Job burnout symptoms measured with Burnout Assessment Tool (BAT) 4-item version. Averaged sum score: range 1-5. Higher score indicates worse outcome.

Depression symptoms measured with Patient health Questionnaire 9 question version (PHQ-9). Total score range 0-27. Higher score indicates worse outcome.

Perceived general life satisfaction measured with single item question with 5 point Likert scale (5=very satisfied; 1=very dissatisfied). Higher score indicates better outcome.

Perceived daily ability to function measured with single item question (score range 0-10). Higher score indicates better outcome.

Amount of the actualized job accommodations measured with single item question. Ordinal 4 item scale. (3=A lot , 2=somewhat, 1=a little, 0=not at all). Higher value indicates better outcome.

Monthly work participation percentage (%) as compared to fulltime working. Higher value indicate better outcome.

Performance in web-based cognitive tests measuring reaction time, attention, executive functions and verbal memory functions. Applied cognitive tests are Task Switching test and Verbal memory test (modified version of the RAVLT).

Self-reported level of social support measured with Oslo Social Support Scale 3-item version (OSSS-3). Sum score range 3-14. Higher score represent better outcome.
