The first 100 participants will be enrolled in the standard of care (control) cohort. These participants will receive treatment with Enbrel® (etanercept) in routine clinical practice and will complete a 52 week study period as per the investigator's standard of care.

Initiation of the personalized patient counselling cohort will begin after 75% of participants in the control cohort have been analyzed and shown not to have high persistence. Participants will receive Enbrel® (etanercept) therapy in routine clinical practice and personalized patient counselling based on the Information-Motivation-Strategy (IMS) model based on Beliefs about Medicines Questionnaire (BMQ) baseline results through a patient assistance program for patients on Enbrel (etanercept) therapy.

In the interventional cohort participants enrolled on the study will receive personalized patient counselling using the IMS-model based on the baseline BMQ results through a patient assistance program for patients on Enbrel (Etanercept) therapy.

A participant is persistent if the date of the last prescription filled plus the number of weeks supply of the prescription is greater than or equal to 52 weeks from enrolment and the eDiary confirms Enbrel® from the prescription was injected. A participant is not persistent if the last prescription filled plus the number of weeks supply of the prescription is less than 52 weeks from enrolment and the eDiary confirms there was no injection of Enbrel®, or, a participant is not persistent if the participant has a gap in treatment of more than 4 consecutive weeks for no medical reason at any time in the 52 week study period.

A participant's adherence is determined as a medication possession ratio (MPR) of at least 80%. The MPR is the ratio of the total number of weeks' supply, based on pharmacy data, of Enbrel® divided by either 52 weeks or duration on study if a physician stops prescribing Enbrel® due to an adverse drug reaction or lack of efficacy.
