Development of Cognitive Interpolation Intervention from Aboriginal Concepts and the Piloting Effect on Prejudice Attitudes Toward Sexual and Gender Minorities

Many Africans assume the call for acceptance of Sexual and Gender Minority (SGM) was an imposition from the Western cultures, unknowing that the history of same-sex sexual relationships predated the invasion of the colonial masters in Africa. As such, SGM persons continue to face serious prejudice and discrimination, which has culminated in the infringement of the socio-medical, psychological, and legal rights. The study set to develop a cognitive interpolation (CI) module from the longstanding aboriginal concepts (i.e. Lakiriboto-Ălàgbedemeji) and pilot the efficacy toward prejudiced attitudes of heterosexual peoples in the Yoruba-speaking region of Nigeria. This study utilized an exploratory research design. Sixteen eligible participants aged between 19 years and 47 years (<i>M</i> = 31.05, SD = 08.17) were purposively selected to participate. Participants were screened for eligibility using double-standard criteria. Participants were assigned to two Focus Groups and the retrieved data were content-analyzed. The outcome revealed that heterosexual participants expressed favorable dispositions toward people with diverse sexual orientations and gender identities after (RCA = +93.80%) exposure to CI intervention than before (RCA = -100%) intervention. The researcher concluded that the study provides preliminary evidence that CII is efficacious for cognitive re-orientation of prejudiced attitudes toward SGM persons and communities. Recommendations and limitations were therefore stated.
