Subjective measurement of participation and environmental barriers and facilitators in population surveys: use of standardized tools with a sub-sample of the Quebec Activity Limitations Survey (QALS)

The collection of data was done by phone with a sub sub-sample (n= 259) of adults with disabilities identified in the Quebec activity limitations survey (QALS QALS-1998), administered by Statistique Statistique-Québec (n =3070).

As, the original questionnaire did not document in a conceptually coherent, sufficient and useful way environmental factors and participation dimensions in order to understand their interactions, both Life Life-H and MQE short versions were added to the sub sub-sample survey assessing five years later the progression of poverty (2003).
