ABSTRACT Government at all levels, non-governmental organizations, traditional leaders and religious organizations have been trying to curb gross immorality in the Nigerian society, but despite their unrelenting effort, it is very sad to note that immorality still persists. To this end the researcher assessed the roles of Christian women in the development ofmoral behaviour of youths in Kaduna State. To achieve this purpose a questionnaire containing five sections was developed and standardized. The information thus received was statistically analyzed using mean, standard deviation and t-test. The result revealed the following: first, the study revealed that parental negligence, broken relationship between God and man, disobedience to sound Christian teachings on moral issues,joblessness and greed are causes of immorality among the youths in Kaduna State. Second, it revealed that immorality has some negative influence on the lives and development of youths in Kaduna State such as sexually transmitted diseases, lung and brain cancer due to alcoholic drinks and drug abuse. Third it revealed that some programmes and activities such as Seminars and workshops, Bible quiz and debates and prayer meetings are being put in place by Christian women to curb immorality among theyouths in Kaduna State. Fourth, the study revealed that Christian mothers have great impact on the lives of the youth because, they contribute to the physical, mental, moral and social training of the youths. Christian mothers also teach the youths faith that leads to achievement of their goals in life through hard work. This study concluded that Christian women have a lot to contribute to the curbing of immorality among the youths in Kaduna State as they spend more time with these youths and with the help of different programmes of events and activities being put in place by them (Christian women) on moral issues. Finally some useful recommendations were made.
