I need a detailed parental report of the child's age and context of acquisition, an estimation of proficiency and the frequence/intensity of L2 daily use. Thanks for sharing your research tool.
The Language Experience and Proficiency Questionnaire (LEAP-Q) is for use with adults and hasn't been tested with children, but you could use it as a model for making your own parental report questionnaire. You may want to supplement it with an objective test of proficiency such as lexical decision (depending on the age of the children in your study). You can then check the correlation between the measures. Also, you may want the parents to rate their own language use as that may partially predict the language proficiency of the children as well.
I really appreciate your suggestions. I finally get a suitable questionnaire for the population and factors I am studying. Ellen Bialystock's lab provide me the Language and Social Background Questionnaire, a parental report that include information about the socio-cultural background of the family (Part A), the linguistic experience with an estimation of proficiency and the type of education attended by the child (Part B) and the dynamic of language use at home in the family and by each one of it's members and for different activities (Part C). This questionnaire is standardized and has been used in several studies with bilingual children.
To supplement the questionnaire with an objective measure of proficiency is a good point in order to maximize the validity of my study. Thanks again!
this semester i am writing my master thesis, which is about phonological and morphological skills of young monolingual and bilingual children in Greece. I would be grateful if you could provide me the language and social background questionnaire. Or i have to communicate Ellen's Bialystok lab??
Dear Maeva, I can't find the questionnaire about the language and socila background you wrote about, could you please send it to me? as I need it for my research focusing on bilingualism. Thank you very much in advance.
This threat is quite old, but I thought I'd post this anyway: There is also the Alberta Language Environment Questionnaire (ALEQ), which is a detailed questionnaire on the language environment of a child: https://www.ualberta.ca/linguistics/cheslcentre/questionnaires#ALEQ
