Nuestro estudio de la atmósfera emocional de los hogares de los pacientes esquizofrénicos en California del Sur ha replicado los descubrimientos británicos en relación con la influencia del ambiente familiar sobre el curso de la esquizofrenia. Como en los estudios británicos, las críticas y la implicación emocional excesiva de un familiar clave para el paciente en el momento de su ingreso constituyen el mejor predictor aislado de recaída sintomática en los nueve meses posteriores al alta hospitalaria. Al igual que en los resultados británicos, la asociación entre la emoción expresada de los familiares y la recaída fue independiente de todas las demas variables investigadas. Los resultados transculturales sobre los efectos preventivos de la medicación sugieren que los clínicos deben considerar la atmósfera emocional del hogar, a la hora de explicar los fracasos de la medicación.
