Abstract
ABSTRACTThe current article is a systematic review and meta-analysis of cross-sectional studies that assess personality traits of long-term participants in ayahuasca rituals. An electronic search was conducted in the SCOPUS, PubMed and Web of Science databases. The systematic review included six final articles. In the meta-analysis, long-term ayahuasca participants, when compared with control groups, obtained: (i) lower significant scores for Harm Avoidance (g = −0.51), Anticipatory Worry (g = −0.56), Fear of Uncertainty (g = −0.27), Shyness with strangers (g = −0.41), Fatigability (g = −0.28) and Purposefulness (g = −0.27); (ii) higher significant scores for Reward Dependence (g = 0.34), Attachment (g = 0.40), Helpfulness (g = 0.38), Self-Transcendence (g = 0.91), Transpersonal Identification (g = 0.68) and Spiritual Acceptance (g = 1.02). The results show a 'social' and 'spiritual' profile for long-term ayahuasca participants that seems to concur with evidence from other psychedelic studies.RESUMENEl presente artículo es una revisión sistemática y metaanálisis de estudios transversales que evalúan los rasgos de personalidad en participantes de larga trayectoria en rituales de ayahuasca. La búsqueda electrónica fue realizada en las bases de datos SCOPUS, PubMed, y Web of Science. La revisión sistemática concluyó con 6 artículos finales. En el metaanálisis, y comparados con el grupo control, los participantes en rituales de ayahuasca obtuvieron: (i) puntajes significativamente más bajos en Evitación del Daño (g = −0.51), Preocupación Anticipatoria (g = −0.56), Miedo a la Incertidumbre (g = −0.27), Timidez frente a Extraños (g = −0.41), Fatigabilidad (g = −0.28) y Orientación (g = −0.27); (ii) puntajes significativamente más altos en Dependencia a la Recompensa (g = 0.34), Apego (g = 0.40), Disposición a la Ayuda (g = 0.38), Autotrascendencia (g = 0.91), Identificación Transpersonal (g = 0.68) y Espiritualidad (g = 1.02). Los resultados muestran cierto perfil 'social' y 'espiritual' de los participantes de larga trayectoria en rituales de ayahuasca, en consonancia con la evidencia encontrada en el campo de estudios con psicodélicos.KEYWORDS: ayahuascapersonalitycross-sectional studiessystematic revisionmeta-analysisPALABRAS CLAVE: ayahuascapersonalidadestudios transversalesrevisión sistemáticametaanálisis Disclosure statement / Conflicto de interesesNo potential conflict of interest was reported by the author. / El autor no ha referido ningún potencial conflicto de interés en relación con este artículo.
