Bias in the perceived prevalence of open defecation: Evidence from Bihar, India

People often form perceptions about how prevalent a behavior is in a social group. However, these perceptions can be inaccurate and biased. While persistent undesirable practices in low-income countries have drawn global attention, evidence regarding people’s perception of how prevalent these practices are is scarce. Among those harmful practices, open defecation in India remains a significant public health concern, where it perpetuates the vicious cycle of disease and poverty. In this study, we focus on measuring the perceived prevalence of open defecation among respondents in Bihar, India. We examined the bias in perceived prevalence, which is defined as a pattern of deviation from the actual prevalence of open defecation. Results showed that respondents who defecate in the open overestimate the prevalence of open defecation, whereas those who consistently use toilets underestimate it. This finding suggests a false consensus bias in the perceived prevalence of open defecation. Scholars, policymakers, and program implementers who seek to correct misperceptions about open defecation by broadcasting real prevalence should be aware of biases in the perceived prevalence and address them in behavior change interventions.

What motivates open defecation? A qualitative study from a rural setting in Nepal

INTRODUCTION

Open defecation is ongoing in Nepal despite the rise in efforts for increasing latrine coverage and its use. Understanding the reasons for open defecation would complement the ongoing efforts to achieve the 'open defecation free' status in Nepal. This study aimed at exploring different motivations of people who practice open defecation in a village in Nepal.

METHODS

This study was conducted among the people from the Hattimudha village in Morang district of eastern Nepal, who practiced open defecation. Maximum variation sampling method was used to recruit participants for 20 in-depth interviews and 2 focus group discussions. We adopted a content analysis approach to analyze the data.

RESULTS

We categorized different reasons for open defecation as motivation by choice and motivation by compulsion. Open defecation by choice as is expressed as a medium for socializing, a habit and an enjoyable outdoor activity that complies with spiritual and religious norms. Open defecation by compulsion include reasons such as not having a latrine at home or having an alternative use for the latrine structures. Despite having a private latrine at home or access to a public latrine, people were compelled to practice open defecation due to constraints of norms restricting latrine use and hygiene issues in general. For women the issues with privacy and issues refraining women to use the same latrine as men compelled women to look for open defecation places.

CONCLUSION

Open defecation is either a voluntary choice or a compulsion. This choice is closely linked with personal preferences, cultural and traditional norms with special concerns for privacy for women and girls in different communities. The ongoing campaigns to promote latrine construction and its use needs to carefully consider these factors in order to reduce the open defecation practices and increase the use of sanitary latrines.
