Outcome Measurement
Given the long duration and multi-modal nature of the
interventions, a range of outcome measures will be used
to ensure evaluation of relevant variables that span the
domains of the International Classification of Functioning
[66]. The variables and measurement tools that will
be employed are summarized in Table 1. These measures
were selected based on the primary and secondary aims
of the trial, clinical relevance, psychometric qualities, and
feasibility (availability, cost and administration time).
Evaluations will be conducted over a 2-day assessment
period at baseline, post-intervention, six months, and 12
months by trained assessors blinded to knowledge of
study hypotheses and group assignment. At each assessment
the assessors will be asked to record their ‘guess’ as
to the group assignment of each participant.
