The HLQ collects quantitative data on the relation between illness and treatment and work performance. The instrument is divided into 4 modules to collect data about absence from work, reduced productivity at paid work, unpaid labor production and impediments to paid and unpaid labor. In the reduced productivity at work module participants were asked to estimate the number of additional hours required to compensate for production losses due to illness on working days over the past 2 weeks.

Change from Baseline was calculated as the Baseline value - Month 24 value. A positive change from Baseline value indicates improvement.

The HLQ collects quantitative data on the relation between illness and treatment and work performance. The instrument is divided into 4 modules to collect data about absence from work, reduced productivity at paid work, unpaid labor production and impediments to paid and unpaid labor. The Unpaid Labour Production Module assesses the amount of hours of unpaid work (including household work, shopping, caring for children and odd jobs around the house), normally performed by the participant, that were taken over by other members of the household, family or friends (unpaid help), and/or by paid workers due to health problems of the participant. Change from Baseline was calculated as the Baseline value - Month 24 value. A positive change from Baseline value indicates improvement.

In the HLQ impediments to paid and unpaid labor module participants were asked "Were you hindered by health problems at your paid work over the past two weeks?" and answered according to the following: 'no not at all = 0', 'yes, a little = 1', 'yes, very = 2'. Participants were also asked whether they had performed 4 unpaid activities (household work, shopping, odd jobs / chores, and childcare), and answered according to the following: Did do, hindered = 1; Did do, not hindered = 0; Did not do, due to health problems = 2; Did not do, due to other reasons = 0. The aggregated score ranges from 0 (no impediments) to 8 (unable to do any of the surveyed activities). Change from Baseline was calculated as the Baseline value - Month 24 value. A positive change from Baseline value indicates improvement.

The physician global assessment of disease activity asks the physician to assess how the participant is doing since their last visit on a scale from 1 (very good, asymptomatic, no limitations in normal activities) to 5 (very poor, severe symptoms that are intolerable, inability to carry out all normal activites). Change from Baseline was calculated as Baseline value - Month 24 value. A positive change from Baseline indicates improvement.

The physician global assessment of disease activity asks the physician to assess how the participant is doing since their last visit on a scale from 1 (very good, asymptomatic, no limitations in normal activities) to 5 (very poor, severe symptoms that are intolerable, inability to carry out all normal activites).

Percent change from Baseline was calculated as (Baseline value - Month 24 value) / Baseline value * 100. A positive change from Baseline indicates improvement.

The patient global assessment of disease activity is a 5-point scale that asks how the participant is doing since their last visit with regard to their rheumatoid arthritis. Participants answer on a scale from 1 (very good, asymptomatic, no limitation in normal activites) to 5 (very poor, very severe symptoms that are intolerable, inability to perform all normal activites). Change from Baseline was calculated as Baseline value - Month 24 value. A positive change from Baseline indicates improvement.

The PASI was is a method for quantifying the intensity of psoriasis, and for evaluating its improvement with treatment. This index is based on the quantitative assessment of three typical signs of psoriatic lesions: erythema, infiltration, and desquamation, combined with the skin surface area involvement. The index has a range from 0.0 to 72.0, with higher scores indicating worse psoriasis.

Psoriatic Arthritis Response Criteria response is defined as improvement from Baseline in at least 2 of 4 criteria, one of which must be joint pain /tenderness or swelling and no worsening in any of the 4 following criteria: • Joint Pain/Tenderness score: Physician assessment of 78 joints for pain/tenderness on a scale from 0 (none) to 3 (severe) with a total score ranging from 0 to 234, with higher scores indicating more severe disability; • Joint Swelling score: Physician assessment of 78 joints for swelling on a scale from 0 (none) to 3 (severe) with a total score ranging from 0 to 234 with higher scores indicating more severe disability; • Patient global assessment of disease activity: Measured on a 5-point scale from 1 (very good) to 5 (very poor); • Physician global assessment of disease activity: Measured on a 5-point scale from 1 (very good) to 5 (very poor).

The HLQ collects quantitative data on the relation between illness and treatment and work performance. The instrument is divided into 4 modules to collect data about absence from work, reduced productivity at paid work, unpaid labor production and impediments to paid and unpaid labor. The absence from work module asks participants to indicate how many days in the past 2 weeks they missed work due to health problems.

The reduced productivity at work module of the HLQ asks participants to estimate the number of additional hours required to compensate for production losses due to illness on working days over the past 2 weeks.

The Unpaid Labour Production Module of the HLQ assesses the amount of hours of unpaid work (including household work, shopping, caring for children and odd jobs around the house), normally performed by the participant, that were taken over by other members of the household, family or friends (unpaid help), and/or by paid workers due to health problems of the participant.

Analysis only includes participants who received unpaid help (103 participants) or paid help (51 participants).

The HLQ impediments to paid and unpaid labor module asks participants how much they were indered by health problems at work over the past 2 weeks on a scale from not at all (0), a little (1) to very (2). Participants were also asked whether they had performed unpaid activities (household work, shopping, odd jobs/chores, childcare) according to the following: Did do, hindered (1); Did do, not hindered (0); Did not do, due to health problems (2); Did not do, due to other reasons (0). The aggregated score ranges from 0 (no impediments) to 8 (unable to do any of the surveyed activities).

The physician global assessment of disease activity asks the physician to assess how the participant is doing since their last visit on a scale from 1 (very good, asymptomatic, no limitations in normal activities) to 5 (very poor, severe symptoms that are intolerable, inability to carry out all normal activites).

The patient global assessment of disease activity is a 5-point scale concerning disease activity that asks how the participant is doing since their last visit with regard to their rheumatoid arthritis. Participants answer on a scale from 1 (very good, asymptomatic, no limitation in normal activites) to 5 (very poor, very severe symptoms that are intolerable, inability to perform all normal activites).
