Eficacia de la actividad física en combinación con la terapia cognitivo conductual sobre la depresión: metaanálisis

Abstract

: The study determined the effects of physical exercise and cognitive behavioural therapy (CBT) on depression. The databases consulted were: Google Scholar, Redalyc, Scielo, ScienceDirect Collection, PsycINFO, EBSCOhost and ProQuest Central. The systematic review was carried out from 14 August 2018 to 10 August 2021. The following eligibility criteria were used: a) randomized trials with inter-group design (control group and experimental group), b) physical exercise, CBT or its combination as independent variables, c) report of both specified and unspecified clinical depression scores, measured by valid psychometric instruments, d) year of publication greater than 1980, and e) participants of both sexes older than 18 years. 103 studies were part of the results (126 effect sizes), for a total of 9,488 participants. Additionally, as an intervention, 36 studies were characterized by using CBT, 62 exercise and 5 used a combination of both. Depression was reduced globally, with a high effect size ( d = -.87, n = 126, 95%CI = -.98, -. 75, Z = -14.53, p <.001, Q = 922.18, gl = TCC y su combinación para reducir la de presión en personas mayores de 18 años. En este contexto, las hipótesis que guiaron el proceso de recolección de datos fueron: a) el ejercicio reduce los síntomas depresivos, b) la TCC reduce los síntomas depresivos, c) el ejercicio en com binación con la TCC tiene un mayor efecto en la reducción de los síntomas depresivos que su impacto individual, y d) las características particulares de las intervenciones moderan la reducción de los síntomas depresivos. 125, I2 = 86.45, p < .001). Physical exercise alone had a high effect size ( d = -.80, n = 73, 95%CI = -.95, -.64, Z = -10.23, p <.001), CBT had a high effect size ( d = -1.03, n = 46, 95%CI = -1.24, -.83, Z = -9.98, p <.001) and exercise in combination with CBT a moderate one ( d = -. 57, n = 7, 95%CI = -1.04, -.10, Z = -2.40, p = .016). In conclusion, exercise, CBT and their combination reduce depression moderately to highly in adults over 18 years of age. consultadas
