Effectiveness of Sensitization Campaigns in Reducing Leprosy-Related Stigma in Rural Togo: Protocol for a Mixed Methods Cluster Randomized Controlled Trial

BACKGROUND

In the global strategy to eliminate leprosy, there remains a need for early case detection to successfully interrupt transmissions. Poor knowledge about leprosy and leprosy-related stigma are key drivers of delayed diagnosis and treatment. Sensitization campaigns to inform and increase awareness among the general population are an integral part of many national neglected tropical disease programs. Despite their importance, the effectiveness of such campaigns has not been rigorously studied in the West African context. A multilingual rural setting with low health literacy in this region presents challenges to the potential impact of sensitization campaigns.

OBJECTIVE

The primary objective of this study is to assess the causal effect of common practice community sensitization campaigns on leprosy-related knowledge and stigma at the community level and among community health volunteers. Additionally, we will test the potential of novel educational audio tools in the 15 most prominent local languages to overcome literacy and language barriers and amplify sensitization campaigns.

METHODS

We will conduct a cluster randomized controlled trial using a sequential mixed methods approach in 60 rural communities across all regions of Togo, West Africa. The study features 2 intervention arms and 1 control arm, with intervention and control assignments made at the community level through randomization. Communities in intervention arm 1 will receive a sensitization campaign in line with the current Togolese national neglected tropical disease program. Communities in intervention arm 2 will receive the same sensitization campaign along with educational audio tools distributed to community households. The control arm will receive no intervention before data collection. Quantitative outcome measures on knowledge and stigma will be collected from a random sample of 1200 individuals. Knowledge will be assessed using the 9-item standardized Knowledge, Attitudes, and Practices Questionnaire. Stigma will be measured using the 7-item Social Distance Scale and the 15-item Explanatory Model Interview Catalogue Community Stigma Scale. We will estimate intention-to-treat effects at the individual level, comparing the outcomes of the intervention and control arms. In an accompanying qualitative component, we will conduct in-depth interviews with community members, community health volunteers, and health care workers in both treatment arms and the control arm to explore intervention and stigma-related experiences.

RESULTS

This paper describes and discusses the protocol for a mixed methods cluster randomized controlled trial. Data collection is planned to be completed in June 2024, with ongoing data analysis. The first results are expected to be submitted for publication by the end of 2024.

CONCLUSIONS

This trial will be among the first to test the causal effectiveness of community-based sensitization campaigns and audio tools to increase knowledge and reduce leprosy-related stigma. As such, the results will inform health policy makers, decision-makers, and public health practitioners designing sensitization campaigns in rural multilingual settings.

The Effects of Immersive Virtual Reality in Reducing Public Stigma of Mental Illness in the University Population of Hong Kong: Randomized Controlled Trial

Background

Public stigma in mental health often brings various adverse effects on people with mental illness. Researchers have been developing different interventions in combating public stigma.

Objective

This study investigates the effects of immersive virtual reality (IVR) in reducing the public stigma of mental illness using a single-blinded randomized control trial.

Methods

A pre-post experimental design with a 1-week follow-up was conducted. Participants (N=206) were recruited through the mass mail system of The Chinese University of Hong Kong and randomized into 3 conditions: immersive animation, text, and control. In the immersive animation condition (n=72), participants experienced the simulation of daily life and the stigma experienced as an animated story protagonist with mixed anxiety and depressive disorder with IVR. In the text condition (n=65), participants experienced an identical story to the immersive animation condition with first-person audio narration using the same virtual reality headset. In the control condition (n=69), participants watched a video about planets with IVR. All participants received interventions with a researcher-assisted Oculus Go virtual reality headset. Participants’ public stigma was measured through self-administered online questionnaires and compared across conditions and at different time points using repeated measures analysis of variance. Simple and sequential mediation analyses on the relationship of condition (immersive animation vs text) and follow-up public stigma with possible mediators, including sense of embodiment and story transportation, were conducted using PROCESS.

Results

Public stigma did not differ significantly across conditions at pre-experiment (P>.99). In the immersive animation and text conditions, public stigma was significantly reduced at postexperiment and at the 1-week follow-up compared to pre-experiment (all with P<.001). Public stigma in the control condition at postexperiment and follow-up remained unchanged compared with pre-experiment (P=.69). Immersive animation had significantly lower public stigma than the control at postexperiment (P=.003) and follow-up (P=.02). Text also had lower public stigma than the control at postexperiment (P=.007) and follow-up (P=.03). However, immersive animation did not significantly differ from text in public stigma at postexperiment and follow-up (both P>.99). In simple mediation models, both sense of embodiment (95% CI –0.22 to 0.46) and story transportation (95% CI –0.18 to 0.00) were not significant mediators. In the sequential mediation model, both sense of embodiment and story transportation were significant sequential mediators. Sense of embodiment was positively associated with story transportation (P<.001), while story transportation was negatively associated with public stigma (P<.001). The indirect effect of the sequential mediation model was significant (95% CI –0.38 to –0.11).

Conclusions

This study provides novel findings and a rigorous comparison in understanding the effects of IVR on public stigma. The findings showed that IVR and text with audio narration performed similarly and significantly in stigma reduction. Sense of embodiment and story transportation were found to be sequentially associated with public stigma reduction.

Mental health stigma in Ukraine: cross-sectional survey

BACKGROUND AND STUDY OBJECTIVES

This study aimed to assess among Ukrainian adults: (1) knowledge of mental disorders; (2) attitudes towards people with mental health disorders, and to the delivery of mental health treatment within the community; and (3) behaviours towards people with mental disorders.

METHODOLOGY

A cross-sectional survey of Ukrainian adults aged 18-60 was conducted. Stigma-related mental health knowledge was measured using the mental health knowledge schedule. Attitude towards people with mental health disorders was assessed using the Community Attitudes towards Mental Illness scale. The Reported and Intended Behaviour scale was used to assess past and future intended behaviour towards people with mental health disorders.

RESULTS

Associations between gender, age, and educational level and the knowledge and attitudes measures were identified. There was evidence of a positive association between being male and positive intended behaviours towards people with mental health disorders [mean difference (MD) = 0.509, 95% confidence interval (CI) 0.021-0.998]. Older age was negatively associated with positive intended behaviours towards people with mental health disorders (MD = -0.017, 95% CI 0.0733 to -0.001). Higher education was positively associated with stigma-related mental health knowledge (MD = 0.438, 95% CI 0.090-0.786), and negatively associated with authoritarian (MD = 0.755, 95% CI 0.295-1.215) attitudes towards people with mental health problems.

CONCLUSION

Overall, the findings indicate a degree of awareness of, and compassion towards, people with mental illness among Ukrainian adults, although this differed according to gender, region, and education level. Results indicate a need for the adoption and scaling-up of anti-stigma interventions that have been demonstrated to be effective.

Reducing HIV stigma among healthcare providers in India using a partly tablet-administered intervention: the DriSti trial

HIV stigma has long been recognized as a significant barrier in the worldwide fight against HIV. Across cultures, stigma has been shown to cause psychological distress and act as a barrier to engagement in care. Health professionals can serve as a crucial source of HIV stigma, with drivers that include fears and transmission misconceptions and pre-existing negative attitudes towards marginalized groups. To increase their impact, stigma reduction interventions need to be scalable and sustainable as well as adaptable to different cultural contexts. The DriSti intervention was designed to meet these needs through an easily adaptable, mostly tablet-administered, interactive intervention delivered to ward staff (n = 1,557) and nursing students (n = 1,625) in 62 Indian institutions, using a cRCT design, with wait-list controls. Six-month outcome analyses, showed significant reductions in misconceptions (p < .001) and worry about acquiring HIV at work (p < .001). Intervention participants also reported significantly greater reductions in endorsement of coercive policies (p < .001) and in the number of situations in which they intended to discriminate against PLWH (p < .001) than control participants. This brief, scaleable intervention could be adapted for similar populations in the region, using different mHealth platforms and thus has important implications for current global stigma reduction initiatives and training curricula.

HIV stigma experiences and stigmatisation before and after a HIV stigma-reduction community "hub" intervention

This study sought to explore, describe and determine whether an HIV stigma-reduction community "hub" intervention would change the HIV stigma experiences of people living with HIV (PLWH) and the stigmatisation by the community in an urban area in South Africa. A convergent parallel mixed-method design with a single case pre-test post-test design and an interpretive description approach was utilised. The sample for this study included 62 PLWH recruited through accessibility sampling and 570 community members recruited through random voluntary sampling. A sub-sample of both groups, selected using purposive voluntary sampling, was utilised for the in-depth interviews about stigma experiences of PLWH, and for perceptions and attitudes of the community toward PLWH. Both quantitative and qualitative data showed that stigma is present. Although no statistically significant changes were found, small practically significant changes were demonstrated in the experiences of PLWH and in the perceptions and attitudes of the community. The extent of changes was much more obvious in the responses of the PLWH and the community during their post-intervention qualitative interviews than the changes found with the quantitative measures. This study thus concludes that the HIV stigma-reduction community hub intervention was successful in initiating the onset of changes in a community through the PLWH and people living close to PLWH (PLC) as community mobilisers active in the community hub to mobilise their own communities towards HIV stigma reduction through social change.

HIV stigma intervention in a low-HIV prevalence setting: a pilot study in an Egyptian healthcare facility

This pilot study is the first to evaluate stigma-reduction intervention in a healthcare setting in Egypt and in the Middle East and North Africa region. It also contributes to knowledge on how to address stigma in low-HIV prevalence settings. A quasi-experimental study design was used to evaluate the effect of anti-HIV stigma intervention in one hospital in Egypt. A control hospital was selected and matched to the intervention hospital by type, size and location. The intervention focused on HIV-related stigma, infection control and medical ethics. Stigma was measured at baseline and at three months post-intervention. A standardized, 10-point scale was developed to measure stigmatizing attitudes and fear-based stigma among participants. Comparisons of overall and job-stratified stigma scores were made across the intervention and control hospitals, before and after the intervention, using two-sample t-test and multivariate regression analysis. Mean stigma scores did not reveal significant differences between the intervention and control hospitals at baseline. After intervention, the overall value-based and fear-based stigma scores were significantly lower in the intervention hospital compared to the control hospital (2.1 and 1.1 compared to 3.8 and 3.2, respectively; p < .001). Context-specific and culturally appropriate HIV stigma-reduction interventions in low-HIV prevalence settings can reduce fear-based and value-based stigma among physicians and nurses.
