Age-disparate transactional sex (ADTS) – transactional sex relationships between adolescent girls and men aged at least five years older – is an established child protection and public health concern [1]. ADTS relationships are characterised by intersecting inequalities related to age, gender, social status and access to resources. These inequities have negative consequences for girls’ agency and risk of exploitation [2-5]. In the sub-Saharan African context, ADTS is associated with negative sexual and reproductive health and socio-developmental outcomes, including a high prevalence of sexually transmitted infections such as HIV [6, 7], sexual coercion, unplanned pregnancy, intimate partner violence, and school dropout among adolescent girls [2, 4, 8, 9].
1.1 Theory: Social norms and strategies to change them
Social norms contribute to the perpetuation of global child and adolescent sexual exploitation and abuse [4, 10, 11] including ADTS in Tanzania [3, 4, 8, 12]. Social norms are informal rules that enforce conformity to behaviours [13] based on mutual social expectations about what others do (descriptive norms), and what others should do (injunctive norms) [13-15]. Norms occur within reference groups - people who individuals’ compare themselves to, and act according to their expectations [16] - and are maintained through (the anticipation of) sanctions for non-adherence, and benefits of adherence [13]. While not implicitly negative, norms can uphold harmful perceptions and behaviours [17-19]. Harmful behaviours such as ADTS can also be upheld by multiple, sometimes conflicting norms, called norm bundles [18]. Unlike norms, which are enforced by reference groups, attitudes and beliefs are individually held and can reinforce or diverge from norms [13, 20]. Pluralistic ignorance occurs when individuals adhere to norms that contradict their personal values [13, 20], and oftens lead to risky behaviours, including ADTS.
Different strategies have been proposed to change harmful norms. Bicchieri (2016) suggests introducing positive new norms that challenge pluralistic ignorance, for example by providing role models of people engaging in healthy norms that align with individual’s personal values and beliefs [20]. Another suggestion is that norms change occurs upon reaching a critical mass, or tipping point, of individual-level changes in attitudes and/or behaviours that reject the existing norm(s) [13, 21, 22]. Mass communication methods can be an efficient way to provide role models and generate this critical mass, by exposing many people to an intervention at once [23]. This can also be aided by diffusion, defined as “the process by which (1) an innovation (2) is communicated through certain channels (3) over time (4) among the members of a social system” [24]. Regarding ADTS, the “innovation” would be creating an enabling, supportive environment for girls and men to avoid ADTS. Public mediums of communicating new messages (such as radio) are theorised to be more effective at promoting diffusion and changing norms than private mediums, as they facilitate common knowledge [25]. The theory posits that those who consume mass media not only adopt new beliefs and attitudes themselves, but also change their beliefs about what others believe (i.e. injunctive norms) as they know that others in their community are also listening [26].
Thus, there is a growing interest in the potential of edutainment to shift norms, based on the premise that media interventions can increase knowledge, foster critical reflection, and shift individual-level attitudes, social norms and behaviours over time [27-30]. Edutainment is defined as “the process of purposely designing and implementing a media message to both entertain and educate in order to increase audience members’ knowledge about an educational issue, create favorable attitudes, shift social norms and change overt behavior” [30]. Edutainment interventions rely on effective messaging strategies, and audiences relating to and engaging emotionally with storylines and characters to achieve their intended changes, a process referred to as narrative transportation [31, 32]. The theory proposes that when individuals become absorbed by a story and “transported” into it, they are better able to internalise new perspectives and ideas [33]. Engaged audiences might vicariously experience sanctions and benefits associated with specific behaviours, leading to normative shifts and behavioural change [27]. Audiences are also less likely to resist new ideas if they are distracted by the story, because they are less aware of the edutainment’s persuasive intent [33]. Thus, audience members with high levels of narrative transportation are believed to be more likely to change their attitudes, intentions and behaviours in line with story messages [33, 34].
1.2 Edutainment to prevent ADTS
In the field of violence against women and girls, edutainment interventions have been shown to improve awareness [35], shift attitudes against its acceptability [36] increase support-seeking behaviours, and promote supportive behaviours from community members [37, 38]. While evidence of the effectiveness of edutainment to prevent ADTS is limited [39], we can draw on learnings from a 2008-2011 radio campaign targeting ADTS in Tanzania called Fataki. In Kiswahili fataki refers to explosives or fireworks, but is also widely used as a term for an older man engaging in ADTS. An evaluation of the campaign found that it increased discussions about cross-generational sex and bystander intervention in these relationships, and decreased relationships reported by women; but no impact was found on men’s reports, nor on the norms driving ADTS [40]. A subsequent, qualitative study revealed that although men internalised the negative messages about cross-generational sex from the campaign, they did not identify with the fataki character, who was portrayed as a wealthy, promiscuous older man and described as “deceptive” and “greedy” [41], providing a possible explanation for the lack of behaviour change reported by men.
Building on this evidence, between 2017 and 2020 the Learning Initiative on Norms, Exploitation and Abuse (LINEA)1 developed a social norms intervention to prevent ADTS in Tanzania. The intervention includes a radio drama and curricula that are designed to target both girls and men, taking a non-stigmatising, gender-transformative approach. The radio drama Msichana wa Kati, which translates as “The Girl in the Middle,” was developed iteratively over multiple phases [42], and draws on the principles of edutainment to help listeners reflect critically on the drivers and consequences of ADTS, and how people can help prevent ADTS in their own communities. It is made up of 39 episodes, 15-20 minutes each, split across three 13-episode acts. Radio was chosen as the mode of delivery as many Tanzanians have access to this medium, either through traditional radios – 43% of Tanzanians in 2018 [43] – or mobile phones; and because of the potential of radio to target hard-to-reach populations and to be easily and cost-effectively scaled up. The intervention was developed in a collaboration between the London School of Hygiene and Tropical Medicine (LSHTM), and Tanzanian organisations Amani Girls Organization (AGO) and Media for Development International (MFDI).
This paper reports findings from a pilot evaluation of a condensed delivery of the radio drama Msichana wa Kati, implemented in the District of Ujiji in Kigoma region, Tanzania over seven weeks in late 2021. This study complements another pilot evaluation of a USB flash drive delivery of the radio drama in Shinyanga region, conducted during the same period [44, 45]. The current study aimed to: (1) explore shifts in ADTS relevant attitudes, beliefs, social norms and behaviours following exposure to the radio drama; (2) investigate how the modality of intervention delivery (radio broadcast only versus afterschool listening sessions for adolescent girls) might influence outcomes; and (3) compare findings between adolescent girls vis-a-vis their caregivers to better understand differences in intervention engagement and impact between audiences. In doing so, we contribute novel insights to improve the development and delivery of edutainment interventions to shift social norms and prevent violence against women and girls.
