Exploring Effective Channels for Behavioural Change Communication in Health Care

Behavioural Change Communication (BCC) is only as powerful as the channel that carries it. A health worker whispering reassurance to a new mother in her courtyard, a radio jingle reminding villagers about handwashing, a WhatsApp forward from a trusted doctor friend – each of these is a channel, and each behaves differently. Choosing the right mix can decide whether a message about immunisation, nutrition, or family planning actually changes what people do. Let us unpack the channels that drive BCC in health care, why some work better in certain settings, and how frontline workers can use them effectively.

What we mean by communication channels in BCC 🔗

A communication channel is simply the route through which a health message travels from a sender to a receiver. In BCC, the goal is not merely to inform but to shift attitudes, social norms, and ultimately behaviour. According to the Indian Journal of Community Medicine, BCC evolved from earlier Information, Education and Communication (IEC) approaches by focusing on creating a conducive environment for sustained behaviour change, not just one-time awareness.

Channels are broadly grouped into two families: interpersonal communication (IPC) and mass communication. A third, hybrid category called mid-media or group communication sits between them. Each family has its own strengths, its own credibility curve, and its own cost.

Local vs. external sources 🔗

One useful way to look at channels is whether the source is local or external. Local sources include ASHAs, ANMs, Anganwadi workers, traditional birth attendants, self-help group members, religious leaders, and respected elders. External sources include television campaigns, government posters, celebrity endorsements, and national radio spots.

Local sources usually score higher on trust because they share the audience’s language, dialect, caste, and lived experience. External sources score higher on reach and consistency. A landmark study on mass media and health promotion in Indian villages concluded that for mass media to actually change behaviour, it must be reinforced by interpersonal communication and supportive changes in the local environment. Neither family works well alone.

Interpersonal communication channels 🔗

Interpersonal communication is the face-to-face, two-way conversation between a health worker and an individual or small group. It is the workhorse of India’s public health system, especially in rural areas where literacy is uneven and trust is built through relationships rather than slogans.

Frontline health workers as primary IPC channels 🔗

India’s three-tier frontline system – ASHAs, ANMs, and Anganwadi Workers – forms the backbone of interpersonal BCC. As India Development Review explains, the communication skills and approach of frontline workers make them arguably the most important component of any government health initiative, because they connect the last mile to the formal healthcare system. ASHAs conduct home visits, counsel pregnant women, and accompany families to facilities. ANMs supervise and provide technical guidance. Anganwadi workers handle nutrition counselling and early childhood care.

Community and group channels 🔗

Beyond one-on-one contact, IPC also happens in groups – Village Health, Sanitation and Nutrition Days (VHSNDs), self-help group meetings, mothers’ committees, and gram sabhas. Research on BBC Media Action’s Shaping Demand and Practices project in Bihar found that group listening sessions, when paired with mobile job aids for frontline workers, generated stronger interpersonal discussion and shifted deep-seated norms like complementary feeding more effectively than standalone digital messages.

Why IPC works especially well in rural India 🔗

A 2026 study from Aligarh district reported in Discover Public Health found significant rural-urban differences in how women trust health information. Rural women continued to depend on interpersonal communication and community health workers, while urban women leaned more on digital and print sources. Rural respondents reported that face-to-face communication offered reassurance and emotional validation that mass media simply could not provide.

Mass communication channels 🔗

Mass communication includes television, radio, newspapers, magazines, cinema slides, hoardings, wall paintings, and increasingly, digital and social media. These channels are designed for one-to-many transmission with consistent messaging across large populations.

Radio 🔗

Radio remains one of the most cost-effective health channels in India, especially through community radio stations and All India Radio’s regional services. It cuts across literacy barriers, reaches agricultural workers during work hours, and uses local dialects. Programmes on maternal nutrition, polio drops, and tuberculosis have been delivered effectively through radio jingles and serial dramas.

Television 🔗

Television offers the combined power of sight, sound, and emotion. National campaigns on polio eradication, organ donation, and COVID-19 vaccination have all relied heavily on TV spots featuring respected figures. According to research summarised in a theoretical framework on mass media and health communication, radio and television are particularly effective at persuading audiences to adopt new behaviours or reminding them of critical information that has already been introduced through other channels.

Print, posters, and wall paintings 🔗

Posters at PHCs, immunisation schedules pinned in Anganwadi centres, and wall paintings on village walls keep messages visible long after a campaign ends. A community-based analysis in Odisha published in PLOS ONE documented the success of “Swasthya Kantha” or health walls – a state initiative where nearly 36% of respondents reported getting health-related information from these painted walls placed at prominent village locations.

Digital and mobile channels 🔗

Mobile health (mHealth) services have emerged as a powerful hybrid. The Kilkari and Mobile Kunji services in Bihar, described in the BBC Media Action evaluation, used voice calls to deliver maternal and child health information directly to families and to support ASHAs during counselling sessions. The state’s National Health Mission BCC strategy now explicitly combines interpersonal communication with print, visual, audio, and “new age media” to tackle rising non-communicable diseases.

Mid-media: the middle ground 🔗

Mid-media channels sit between IPC and mass media and include street plays (nukkad natak), folk performances, puppet shows, video van screenings, health melas, and exhibitions. They are particularly powerful in low-literacy settings because they entertain while educating. The MANTHAN project in Uttar Pradesh, for instance, combined mass media with mid-media activities like street plays and village video shows to promote maternal and newborn health behaviours, supplemented by ASHA-led interpersonal counselling.

Rural vs. urban media mixes 🔗

The same campaign rarely works identically in a Bengaluru apartment complex and a Bastar village. A Population Council analysis of media reach in rural Uttar Pradesh showed that mass media exposure varies sharply by audience segment – women with no schooling, those from scheduled castes and tribes, and residents of very small villages had dramatically lower exposure than their more privileged counterparts. This means urban campaigns can rely more heavily on TV, digital, and print, while rural campaigns must anchor themselves in IPC and mid-media, with mass media playing a reinforcing role.

In urban settings, the channel mix tilts toward social media influencers, WhatsApp groups, OOH hoardings, app notifications, and clinic-based counselling. In rural settings, ASHAs, VHSNDs, community radio, and wall paintings carry more weight, with TV and mobile messaging gradually catching up.

Tips for effective interpersonal communication 🔗

Even the best message fails if delivered poorly. Frontline workers can sharpen their IPC skills by remembering a few practical points.

Practise active listening. Real counselling is not lecturing. The Mobile Academy refresher training for ASHAs in Rajasthan, evaluated in a BMJ Open study, found that ASHAs reported learning “how to speak with love” – pausing, acknowledging concerns, and asking open questions before offering advice. People act on advice when they feel heard first.

Use simple, local language. Replace jargon with familiar terms. Saying “high blood pressure” instead of “hypertension” or “heart attack” instead of “myocardial infarction” makes messages land. Tailor your idiom to the dialect spoken in that village or basti.

Respect cultural norms and family dynamics. In many Indian households, mothers-in-law, husbands, and elders influence health decisions more than the woman herself. Effective IPC includes these decision-makers, not just the patient.

Use visual job aids. Flipbooks, counselling cards, and apps like Mobile Kunji give the worker a structured prompt and the family something concrete to look at. Digital facilitated tools were associated with measurable improvements in frontline worker performance in Bihar.

Follow up. Behaviour change is rarely a single conversation. Repeated home visits, reminder calls, and small check-ins build the trust that converts knowledge into action.

Tips for effective mass communication 🔗

Mass communication has its own discipline. A few principles consistently separate campaigns that move the needle from those that fade.

Prioritise themes by urgency and impact. India faces a vast set of health challenges, so mass media energy should focus first on issues with the heaviest burden – child immunisation, maternal health, nutrition, NCDs, and emerging infectious diseases – before spreading to less urgent topics.

Anchor messages in evidence. Use verifiable facts and clear data. Audiences, especially educated urban audiences, increasingly fact-check claims, so credibility matters.

Layer the channels – the “surround sound” approach. The Bihar programme is often cited as a model precisely because it “surrounded” audiences with complementary channels: TV, radio, mobile services, community events, and IPC. A layered approach improves diffusion, increases credibility, and gives the audience multiple chances to encounter the message.

Pre-test creatives with the target audience. A poster that works in Hyderabad may confuse viewers in Hazaribagh. Pilot testing prevents costly misfires.

Combine positive and “negative” framing carefully. Anti-tobacco messaging in India has shown that fear appeals (graphic warnings on cigarette packs) can drive behaviour change when paired with supportive resources like quitlines. But fear alone, without a clear action path, backfires.

Plan for misinformation. Research on rural Odisha highlighted that misinformation and inadequate infrastructure are persistent barriers to mass-media effectiveness. Building correction loops – through frontline workers, fact-check pages, and trusted community influencers – is now part of any serious BCC strategy.

Bringing channels together 🔗

No single channel changes behaviour at scale. The strongest BCC strategies use mass media to set the agenda, mid-media to make it memorable, and interpersonal communication to seal the deal. They respect the difference between urban and rural audiences, between local and external sources of trust, and between knowing something and actually doing it. For a country as diverse as India, the channel mix is not a luxury – it is the strategy.

What do you think? If you were designing a BCC campaign to improve adolescent nutrition in your district, which channels would you place at the centre – and which would you use only as reinforcement? Have you noticed a health message in your own community that worked because of the channel it travelled through, rather than the words it used?
