Motivation study. Clinical empirical study on the effect of motivation feedback on motivation and compliance.

Currently there is a lot of unclarity about the way motivation influences the
treatment as well as what possibilities there are to positively influence the
motivation. A better comprehension of the role of motivation is important
because motivation problems coincide with dropout, a lack of compliance and
thence a less favourable treatment result.

We want to study the effect of feedback to the clinician concerning the
motivation of the patient to see if this feedback leads to a better motivation,
compliance and treatment result because the clinician is more aware of the
motivation (or the lack of motivation) of the patient and can take this into
account in the treatment of the patient. Also we want to study what factors
coincide with (changes in) the motivation for treatment.

This study is a clustered randomised study that is meant to establish the
influence of motivation feedback on the motivation and compliance.

Motivation feedback means that the clinician receives feedback concerning the
motivation of the patient on several occasions. This feedback will take place
after the baseline measurement and after 6 months. The clinician will also
provide oneself with feedback during every session. The feedback by session
begins in the first month after the baseline measurement and ends after 12
months. Two groups will be compared with each other. The first group will
receive a treatment including motivation feedback en the second group will
receive a treatment without motivation feedback.

The research participants will be interviewed 3 times by means of a series of
questionnaires. The first time takes place at the beginning of the study, the
second time after 6 months and the third time after 12 months. The additional
burden for the research participant (besides the ROM-measurement) is stipulated
by an interview duration of approximately 70 minutes. At the beginning of the
study the research participants are also classified (based on their clinician)
into 1 of 2 groups. Besides these interviews, the research participants in
group 1 are also requested to take two short questionnaires that comprise of 6
questions in total. The research participants in group 2 don*t have to do this.
As far as we can tell this additional burden entails no obvious risks.
