An experimental study was carried out to assess the effectiveness of training on assertive behaviour and self-esteem among adolescent girls of South Side Girls’ High school, Kharagpur, West Bengal. 80 participants were selected by non-probability convenience sampling. Quasi-experimental one group pre-test post-test research design was adopted. Rathus assertiveness schedule (1973) was used for assessing assertive behavior, Rosenberg self-esteem scale (1965) used for self-esteem. Data were collected by using paper-pencil test. After administering the training on assertive behavior and self-esteem, 66% students were assertive (previously 10%), 6% were very non-assertive (previously 30%) and 8% remained aggressive (previously 25%) and 71% had higher self-esteem (previously 14%), and only 9% remained problematic low self-esteem (previously 26%). The obtained mean/SD of post-test score on assertive behavior and self-esteem are 26.46/18.35, 25.25/4.2. Calculated ‘r’ is 0.58; related ‘t’ value on pre- test on assertive behavior/self-esteem 6.28; i.e., significant, P<0.05 level. There are significant associations between pre-test level of assertive behavior with residential area (P=0.035), mothers’ education (P=0.003), sources of knowledge about assertive behavior/self-esteem (P<0.001). It can be suggested to replicate the study with control- experimental groups selected through simple randomization.
