Process of adapting a motivational intervention for contraceptive use in Mexican teenage mothers

Abstract

Aim. Adolescent pregnancy is a problem in Latin America that requires the implementation of effective interventions. This study describes the adaptation process of Computer Assisted Motivational Intervention (CAMI) for increasing contraceptive use and reducing subsequent pregnancies in the context of adolescent mothers in Northern Mexico. Methods. The McKleroy Intervention Adaptation Model was applied: 1) assessment of the local context; 2) evaluation of the intervention with experts; 3) preparation of the content, activities and materials; 4) pilot testing of the adapted version; and 5) implementation, with an exploratory and descriptive design. Results. The CAMI-Spa version was obtained with modifications and a favorable trend in scores on contraceptive variables (pretest vs. posttest) as attitude [120.67(SD ± 12.36) vs. 138.40(SD ± 7.20)], knowledge [28.00(SD ± 8.76) vs 44.00(SD ± 8.49)], processes of change [78.67(SD ± 20.83) vs 108.60(SD ± 9.21)] and self-efficacy [43.00(SD ± 10.37) vs 56.80(SD ± 17.38)]. Conclusion. The use of an intervention adaptation model allowed for the adjustment of the intervention to the context of Mexican adolescent mothers without affecting its key components, which could ensure the effect on increased contraceptive use.
