Material y Método. El estudio es de tipo cuantitativo, nivel aplicativo, método correlacional de corte transversal. La muestra se obtuvo mediante el muestreo probabilístico de proporciones para poblaciones finitas y aleatorias simple quedando conformada por 87 estudiantes del primer al tercer año de estudios secundarios. La técnica fue la encuesta y los instrumentos fueron el Cuestionario de Juego Patológico de South Oaks (SOGS) modificado y la Escala de funcionamiento Familiar de Olson FACES III modificado, aplicado previo consentimiento informado.

En cuanto a la dimensión de cohesión familiar 71%(62) presentan cohesión familiar aglutinada o enmarañada, 23%(20) unida o conectada, 4%(3) separada y 2%(2) desligada ; mientras que en la dimensión Adaptabilidad 69%(60) presenta adaptabilidad familiar Caótica y 23%(20) presenta adaptabilidad Flexible , 6%(5) adaptabilidad estructurada y 2%(2) adaptabilidad rígida .En cuanto al Nivel de Ludopatía del 100%(87), 57% (50). Tienen nivel medio 23%(20) nivel alto y 20%(17) nivel bajo. Asimismo se halló que de aquellos que presentaron un nivel de ludopatía alto del 100% (20); 65 % (13) presenta una dinámica familiar funcional y 35% (7) disfuncionalidad familiar; en cuanto a aquellos que presentaron un nivel de ludopatía medio del 100% (50), 52% (26) presenta disfuncionalidad familiar y 48% (24) presentan dinámica familiar funcional. Asimismo aquellos que presentaron un nivel de ludopatía bajo del 100% (17), 64% (11) presenta una disfunción familiar y el 36% (6) presentan dinámica funcional. Al realizar la prueba de hipótesis mediante la prueba de Ji cuadrado se encontró la existencia de asociación entre el tipo de funcionamiento familiar y el nivel de ludopatía en adolescentes de la Institución Educativa Técnica “República de Bolivia”. Conclusión. Existe relación entre tipo de funcionamiento familiar y nivel de ludopatía en los adolescentes por lo cual se puede afirmar que el tipo de funcionamiento familiar es uno de los factores determinantes en la adopción de conductas de riesgo en los adolescentes en la población en estudio el cual fue comprobado mediante Prueba de Ji Cuadrado.

Also those who had a low level of gambling 100 % (17), 64 % (11) has a family dysfunction and 36% (6) have functional dynamics. When testing hypotheses by Chi-square test the existence of association between family functioning and the level of problem gambling in adolescents Technical School “Republic of Bolivia " was found. Conclusions.
