Abstract: Objective: To describe and explain social participation of persons with the adult and mild phenotype of myotonic dystrophy type 1 (DM1). Methods: A random sample of 200 subjects with DM1 (42 mild phenotype, 158 adult phenotype). Level of social participation and satisfaction was assessed with the Assessment of Life Habits (LIFE-H). Environmental factors were assessed with the Measure of the Quality of the Environment. Personal Factors were assessed with standardized instruments including Berg Balance Scale, Krupps Fatigue Severity Scale, and Manual Muscle Testing. Results: Participants with the adult phenotype demonstrated significantly lower participation level than those with the mild phenotype on 8 out of the 11 categories of the LIFE-H. Lower levels of accomplishment were reported in Mobility, Housing, Fitness, Nutrition, Personal Care, Employment, Recreation and Community Life categories among the adult phenotypes. The Recreation category was the most affected category with four out of seven items revealing compromised accomplishment among 22% to 27% of individuals. The lowest satisfaction score was observed in the Employment and Recreation categories. The predictors of the most restricted participation domains being Housing, Mobility, Employment and Recreation were determined with a logistic regression analysis. Participants reported disturbed participation in a large proportion (45-61%) for all domains. Lower extremity strength [OR = 15.4 – 5.5; p < 0.05] and higher fatigue [OR = 6.0 – 2.6; p < 0.05] were significantly present in participants with disturbed participation for all domains. For environmental factors, social support [OR = 3.6 – 2.5; p < 0.05] and public services [OR = 2.8 – 2.4; p < 0.05] were significantly perceived as barriers for participants with disturbed participation for most domains. Conclusion: This doctoral program has permited to better understand social participation in DM1. The results will help to elaborate a more comprehensive evaluation scheme and to develop intervention to promote optimal social participation in this population.
