Study Purpose View help for Study Purpose

The specific aims of this 3-year longitudinal study of persons with the disease and their care partners are: 1) characterize social self-management trajectories over a 3-year period; 2) estimate the degree to which expressive nonverbal capacity predicts the trajectory; and 3) determine the moderating effect of gender on the association between expressive capacity and change in social self-management.

Study Design View help for Study Design

There are seven in-person assessments of approximately two hours duration and in-person, one at baseline and one every six months thereafter, with six in a clinical research lab and one in the home. Between the 6-month full assessments, there is an additional brief telephone call (15 to 30 minutes), totaling seven phone calls over three years. Frequent points of contact, while also building statistical power, increases the possibility of capturing remembered details of daily life that send health patterns into non-linear trajectories, such as anniversaries, retirement, bad colds or significant family events.

At each session, initially, participants with Parkinson's Disease (PD) and care partners are interviewed separately with parallel questionnaires to assess each of their daily life activities, health and quality of life. After separate interviews, the two are interviewed together about their combined social self-management. Participants with PD are asked to take their medication approximately 45 minutes before their assessment session in order to be "on", that is, moving and functioning at maximal capacity during their session.

A number of participants, over the course of the study, were unable to come to the lab for their scheduled in-person assessments, completing our standard telephone assessment instead. These data are collected in one data file. Additionally, these participants' data have been incorporated into the larger in-person data sets, using the following procedure. The Short Form (version 2) Health Survey (SF12v2) and the Social Isolation Domain of the Nottingham Health Profile variables are collected in all assessments, so these data have been added from the alternate phone interviews to the larger in-person data sets exactly, and their scores calculated. The Parkinson's Disease Questionnaire (PDQ) 8 consists of items from the PDQ 39, so the PDQ 8 data from the alternate phone interviews has been added to the corresponding PDQ 39 variables (see list, below) in the larger in-person data sets. PDQ 8 scores were then calculated for all participants. For information updates, any medicine changes mentioned in the alternate phone interviews have been added to the medication change variables in the larger in-person data sets. All other types of updates from the alternate phone interviews have been added to the general updates variables.

Participants were recruited via the Movement Disorders Clinic at Boston Medical Center, Parkinson's Disease support and other group meetings, and ads on websites.

Individuals who respond to recruitment are screened in a 1-hour session by a movement disorders neurologist and movement disorders nurse specialist for eligibility and to collect demographic data and conduct a medical history protocol.
