Youth centers both develop youths' sense of citizenship and their soci
al integration and discourage their delinquency These centers, numerou
s in Hong Kong, provide essential social services for youths. Promotin
g youths' continuous participation in youth centers is, therefore, a r
ecurrent issue in Hong Kong. A model-the sequential specificity model-
appears to be useful in addressing this goat. This model differentiate
s the sequence of participation and the corresponding specific and non
specific determinants. Knowledge and the attitude toward youth center
services are specific determinants hypothesized to affect participants
' participation intention more strongly than nonparticipants'. Analysi
s of data from a sample of 1,755 high school students in Hong Kong sup
ports this hypothesis.
