Relevant beliefs for HIV Testing and Counselling Services among Tuberculosis Suspected patients in Kassala State, Sudan

Résumé

Abstract Background: There is limited information about the psychosocial (sub-) determinants regarding the use of HIV Testing and Counselling (HTC) services among Tuberculosis(TB) suspected patients in Sudan. This study aimed to assess the psychosocial beliefs related to the intention to use HTC services among TB suspected patients and to establish the relevance of these beliefs for developing behaviour change interventions. Methods: TB suspected patients (N= 383) completed a cross-sectional questionnaire from four separate TB facilities. The questionnaire was based on the Reasoned Action Approach theory. Eligibility criteria included attending Tuberculosis Management Units in Kassala State as suspected TB patients and aged 18-64 years. A Confidence Interval Based Estimation of Relevance (CIBER) analysis approach was employed to investigate the effects of the beliefs on the intention to use the HTC services and to establish their relevance to be targeted in behaviour change interventions. Results: The CIBER results showed the beliefs included in the study accounted for 59% to 70% of the variance in intention to use HTC services. The belief "My friends think I have to use the HTC services" was positively associated with the intent to use HTC, and it is highly relevant for interventions. The belief “If I would fear to be stigmatized if I get HIV positive result" was negatively related to the intention to use the HTC services and highly relevant belief. The belief “If I use HTC services, the health care providers will keep my HIV test result confidential" was strongly associated with the intention to use HTC services. However, it was not a very low relevant belief. Past experience with HTC services was weakly associated with the intention to use HTC services. Conclusion: The intention to use HTC was a function of psychosocial beliefs. The belief investigated varied in their relevance for interventions designed to encourage the use of HTC services. Interventions to intention to use HIV testing and counselling services should address the most relevant beliefs (sub-determinants). Further study is needed to establish the relevance of sub-determinants of the intention to use HTC services.
