Career development is dependent on career maturity and adolescence is an important period when students decide about an occupation. It is necessary to know the effect of stress coping strategies on the career maturity of 16-18 years adolescent students. The objective of the present study was to prepare a model for career maturity in adolescent students based on their stress-coping strategies. To conduct the study, 400 adolescent students between the age range of 16-18 years were selected from government and private schools operational in the Durg district of Chhattisgarh. Out of the total sample of 400, 200 were adolescent boys and 200 were adolescent girls. Purposive sampling was used for data collection. The Indian adaptation of the career maturity inventory developed by Nirmala Gupta (1989) was used to assess career maturity in adolescent students. To assess stress coping strategies of adolescent students, an inventory prepared by Tobin (2001) was used. It was found that the stress coping strategy in the form of problem-solving, expressing emotions, problem avoidance, social support, wishful thinking, cognitive restructuring and social withdrawal accounted for 41.2% variance in career maturity in adolescent students. Based on results, it was concluded that coping strategies namely problem-solving, cognitive restructuring, expressing emotions and social support develop good career maturity in 16-18 years age group adolescent students while coping strategies namely problem avoidance, wishful thinking, self-criticism and social withdrawal are detrimental to career maturity in 16-18 years age group adolescent students. It can also be concluded that stress-coping strategies in the form of problem-solving, expressing emotions, problem avoidance, social support, wishful thinking, cognitive restructuring and social withdrawal can predict career maturity in adolescent students on a threshold of adulthood.
