Diener, «Dembo-Rubinstein Scale of self-esteem and level of aspirations», version by А.М. Prikhozhan. The sample 237 pupils aged 15-18 years. The conflict between self-esteem and aspirations is revealed in 52% respondents.

When there is an explicit conflict, the number of negative relationships increases, which is an indicator of the negative impact of self-esteem conflict on all parameters of psychological wellbeing. The specific character of changes in psychological wellbeing associated with gender and intensity of conflicts is revealed.
