Background: Rubber production is an important component of the Sri Lankan economy. Prior reports have raised concerns about poverty and poor physical and social living conditions among rubber tappers. Objective: To assess rubber tappers’ psychological health and distress. Methods and Material: A cross-sectional survey was conducted among 300 rubber tappers in two large rubber plantations in southern Sri Lanka from September to November 2014. Structured questionnaires including the Peradeniya Depression Scale (PDS) and the 10-item Perceived Stress Scale (PSS-10) were administered. The prevalences of depression and stress were calculated, including across sociodemographic and work history variables of interest. Results: Each plantation contributed 150 of the 300 participants. The majority were women (n = 183, 61%) with a median age of 47 years (range 21 to 89). Based on the PDS, 9% of the rubber tappers screened positive for depression. While on the PSS-10, 10% demonstrated a high level of perceived stress. On log-binomial regression, persons who were widowed, divorced, or separated compared to being married had a higher prevalence of depression and high stress. A higher prevalence of stress was found in Tamil versus Sinhalese as well as Christian versus Buddhist participants. A higher prevalence of depression was seen in workers with over 30 years of experience compared to less experienced counterparts. Conclusions: Depression was more common in rubber tappers in this study than among other non-plantation Sri Lankan populations. Further research is needed to elucidate factors associated with psychological distress and to foster support mechanisms for the rubber tappers.
