Brief Summary:

Adherence is an active process wherein the patient acts in collaboration with the medical and paramedical staff in order to improve his/her health. Adherence to medication comprises of implementation and persistence and it is estimated to be around 50% in various chronic illnesses, including Multiple Sclerosis (MS). MS patients who fail to properly adhere to their DMTs regimen may be at increased risk for the development of new central nervous system lesions, exacerbations, increased disabilities and poorer quality of life. Plausible reasons for the low adherence rates in MS mentioned in the literature include patients' attributes, condition attributes and therapy related factors.

The objective of this study is to develop a personal profile of adherence based in the factors mentioned above. In the first part of the study patients will be followed up and the profile My Multiple Sclerosis Perception Adherence Scoring System (MyMS_PASS) will be created and tested. In the second part, patients with non-optimal rates of adherence will receive tailored intervention in order to improve therapy to treatment. This work may serve as a model for the study of adherence to therapy and the development of interventions in MS as well as in other chronic diseases.

Arm Intervention/treatment
Experimental: Behavioral Intervention
Participants in this group will receive tailored psychological intervention to promote adherence to their drug therapy.
Behavioral: Behavioral Intervention
Three types of intervention will be used: a) Interventions aimed to dealing with cognitions and habits will be based on cognitive-behavioral therapy (CBT) principles. b) Interventions aimed to dealing with affective factors that interfere with adherence will be based on dynamic therapy, crisis intervention and supportive elements. c) In the case of condition-related or therapy related barriers to adherence, psycho-educational multidisciplinary interventions of 1-2 appointments will be offered. Education about injection techniques and about reasonable expectations from therapy, and from MS itself, are a key strategy to successfully maintaining adherence.

No Intervention: Non Intervention group
Participants in this group will be observed but will not receive any intervention.

Primary Outcome Measures :
  1. Adherence to therapy by assessment of remaining pills/medication claims electronic records [ Time Frame: 24 months ]
    For oral therapy: Adherence to therapy as indicated by the number of pills remaining in the pills empty packages

  2. Adherence to therapy according to ProMas [ Time Frame: 24 months ]
    Improvement in therapy adherence as measured by Probabilistic Medication Adherence Scale (ProMas). Adherence categories are low (sum score 0-4), medium low (sum score 5-9), medium-high (sum score 10-14) and high (sum score 15-18)

  3. Adherence to therapy according to MS-TAQ [ Time Frame: 24 months ]
    Improvement in therapy adherence as measured by Multiple Sclerosis Treatment Adherence Questionnaire (MSTEQ). The items from MS-TAQ used in this analysis tapped whether the participant did not take a prescribed dose in the last four weeks and the reported number of these doses. In cases of reported non-adherence, the percentage was calculated per regiment.

Secondary Outcome Measures :
  1. Improvement in quality of life [ Time Frame: 24 months ]
    Improvement in quality of life as measured by the World Health Organization Quality of Life-Bref instrument (WHOQOL-Bref)
