Measuring sexual behaviour in Malawi: a triangulation of three data collection instruments

Experience of social harms among female sex workers following HIV self-test distribution in Malawi: results of a cohort study

BACKGROUND

In Malawi, female sex workers (FSW) have high HIV incidence and regular testing is suggested. HIV self-testing (HIVST) is a safe and acceptable alternative to standard testing services. This study assessed; whether social harms were more likely to be reported after HIVST distribution to FSW by peer distributors than after facility-based HIV testing and whether FSW regretted HIVST use or experienced associated relationship problems.

METHODS

Peer HIVST distributors, who were FSW, were recruited in Blantyre district, Malawi between February and July 2017. Among HIVST recipients a prospective cohort was recruited. Interviews were conducted at baseline and at end-line, 3 months later. Participants completed daily sexual activity diaries. End-line data were analysed using logistic regression to assess whether regret or relationship problems were associated with HIVST use. Sexual activity data were analysed using Generalised Estimating Equations to assess whether HIVST use was temporally associated with an increase in social harms.

RESULTS

Of 265 FSW recruited and offered HIVST, 131 completed both interviews. Of these, 31/131(23.7%) reported initial regret after HIVST use, this reduced to 23/131(17.6%) at the 3-month follow-up. Relationship problems were reported by 12/131(9.2%). Regret about HIVST use was less commonly reported in those aged 26-35 years compared to those aged 16-25 years (OR immediate regret-0.40 95% CI 0.16-1.01) (OR current regret-0.22 95% CI 0.07 - 0.71) and was not associated with the HIVST result. There was limited evidence that reports of verbal abuse perpetrated by clients in the week following HIVST use were greater than when there was no testing in the preceding week. There was no evidence for increases in any other social harms. There was some evidence of coercion to test, most commonly initiated by the peer distributor.

CONCLUSIONS

Little evidence was found that the peer distribution model was associated with increased levels of social harms, however programmes aimed at reaching FSW need to carefully consider possible unintended consequences of their service delivery approaches, including the potential for peer distributors to coerce individuals to test or disclose their test results and alternative distribution models may need to be considered.

Comparison of Computer-Assisted Self-Interview Versus Clinician Interview for Self-Reported Vulvovaginal Symptoms

ABSTRACT

This secondary analysis (N = 43) compared computer-assisted self-interview (CASI) to clinician interview for self-report of 8 vulvovaginal symptoms. Concordance was moderate between interview modes (range, 70-86%) with itching and odor having highest agreement. Although prior reports suggest more responses on CASI, we found CASI did not significantly increase self-report of symptoms over clinician interview.

Comparison of audio computer-assisted self-interview (ACASI) to other survey modes in sexual behaviour surveys in Asia and Sub-Saharan Africa: A systematic literature review (Preprint)

Background

Reliable data about sexual behaviors is fundamental in the prevention and control of HIV, hepatitis, and other sexually transmitted infections. Generally, sexual behaviors are regarded as a sociocultural taboo in Africa and Asia, and this results in biased sexual behavior survey data due to social desirability. Various modes of survey delivery, including audio computer-assisted self-interviews (ACASIs), have been investigated to improve data quality.

Objective

This study aimed to review studies that compared the ACASI mode to other survey modes in sexual behavior surveys in Asia and sub-Saharan Africa to ascertain the impact of survey mode on responses to sexual behavior questions.

Methods

A systematic literature review was conducted according to the Joanna Briggs Institute Manual for Evidence Synthesis. The review protocol was registered at PROSPERO (International Prospective Register of Systematic Reviews). Six databases were searched.

Results

A total of 21 papers were included. The face-to-face interview (FTFI) mode was the survey mode most frequently compared to the ACASI mode. Among the most commonly reported outcome variable groups, ACASI participants were more likely to report sexual behaviors, such as “forced sex,” “multiple partners,” “transactional sex,” and “ever had sex,” as compared to FTFI participants. In addition to the survey mode effect, other factors were found to have had an impact on data quality, for example, participant characteristics, social norms, study design, and data collection setting.

Conclusions

Use of ACASIs for administering sexual behavior surveys among populations in Asia and sub-Saharan Africa demonstrated higher reports for some sexual behaviors than the use of FTFIs. More studies that compare the ACASI mode to other survey modes would improve our understanding of the usefulness of ACASIs in sexual behavior surveys in these regions.

Exploring social harms during distribution of HIV self-testing kits using mixed-methods approaches in Malawi

INTRODUCTION

HIV self-testing (HIVST) provides couples and individuals with a discreet, convenient and empowering testing option. As with all HIV testing, potential harms must be anticipated and mitigated to optimize individual and public health benefits. Here, we describe social harms (SHs) reported during HIVST implementation in Malawi, and propose a framework for grading and responding to harms, according to their severity.

METHODS

We report findings from six HIVST implementation studies in Malawi (2011 to 2017) that included substudies investigating SH reports. Qualitative methods included focus group discussions, in-depth interviews and critical incident interviews. Earlier studies used intensive quantitative methods (post-test questionnaires for intimate partner violence, household surveys, investigation of all deaths in HIVST communities). Later studies used post-marketing reporting with/without community engagement. Pharmacovigilance methodology (whereby potentially life-threatening/changing events are defined as "serious") was used to grade SH severity, assuming more complete passive reporting for serious events.

RESULTS

During distribution of 175,683 HIVST kits, predominantly under passive SH reporting, 25 serious SHs were reported from 19 (0.011%) self-testers, including 15 partners in eight couples with newly identified HIV discordancy, and one perinatally infected adolescent. There were no deaths or suicides. Marriage break-up was the most commonly reported serious SH (sixteen individuals; eight couples), particularly among serodiscordant couples. Among new concordant HIV-positive couples, blame and frustration was common but rarely (one episode) led to serious SHs. Among concordant HIV-negative couples, increased trust and stronger relationships were reported. Coercion to test or disclose was generally considered "well-intentioned" within established couples. Women felt empowered and were assertive when offering HIVST test kits to their partners. Some women who persuaded their partner to test, however, did report SHs, including verbal or physical abuse and economic hardship.

CONCLUSIONS

After more than six years of large-scale HIVST implementation and in-depth investigation of SHs in Malawi, we identified approximately one serious reported SH per 10,000 HIVST kits distributed, predominantly break-up of married serodiscordant couples. Both "active" and "passive" reporting systems identified serious SH events, although with more complete capture by "active" systems. As HIVST is scaled-up, efforts to support and further optimize community-led SH monitoring should be prioritized alongside HIVST distribution.
