The Seattle Amyotrophic Lateral Sclerosis (ALS) Patient Project Database: observational, longitudinal, dyadic characterization of people with ALS and their partners.

Introduction: The median survival time in ALS is approximately 3 years, but survival times range from less than a year to more than 10 years and much variance in disease course remains to be explained. As is true for physical outcomes, there is considerable variance in QOL, which is influenced by psychological health, coping, and social support, among other psychosocial factors. The Seattle ALS Patient Project Database (SALSPPD) provides a unique opportunity for researchers to address established and novel hypotheses about disease progression and QOL in ALS. Methods: The SALSPPD is a longitudinal dataset of people with ALS ( Results: The provided data dictionary includes details of the over 500 variables measured in the study, which have been subsetted into domain datasets. Domains address physical, psychological, social, and behavioral status on the person with ALS and their partners. Missing data were coded according to their mechanism. Data are available in two formats: The Discussion: The SALSPPD will provide a rich resource to scientists interested in the natural history of ALS, psychosocial effects on ALS outcomes and vice versa, and psychosocial and disease outcomes of treatments.
