It is widely accepted that community-based interventions are vital strategies towards reduction of maternal and neonatal mortalities in developing counties. This study aimed at finding the impact a Community Based Continuous Training (CBCT) project in improving couples’ knowledge on birth preparedness and complication readiness in rural Tanzania.The quasi-experimental study design with control was adopted to determine the impact of CBCT in improving knowledge on birth preparedness and complication readiness. The study was conducted from June 2017 until March 2018. A multi-stage sampling technique was employed to obtain 561couples. Pre-test and post-training intervention information were collected using semi-structured questionnaires. The impact of CBCT was determined using both independent t-test and paired t-test. Linear regression analysis was used to establish the association between the project and the change in knowledge mean scores. The effect size was calculated using Cohen’s d. At post-test assessment, knowledge mean scores were significantly higher in the intervention group among both pregnant women (m = 14.47±5.49) and their male partners (m = 14.1 ±5.76) as compared to control group among both pregnant women (m = 9.09±6.44) and their male partners (m = 9.98±6.65) with large effect size of 0.9 among pregnant women and medium effect size of 0.66 among male respondents. When the mean scores were compared within groups among both pregnant women and male partners in the intervention group, there were a significant increase in knowledge mean scores at post-test assessment as compared to pre-test assessment with large effect size of Cohen’s d = 1.4 among pregnant women and 1.5 among male partners. After adjusting for the confounders, the predictors of change in knowledge among pregnant women were the CBCT project (β= 0.346, p<0.000) and ethnic group [Mambwe (β= -0.524, p = 0.001)] and the predictors of change in knowledge among male partners were the CBCT project (β= 1.058, p<0.001) and walking distance [more than five kilometers (β= -0.55, p<0.05)]. This interventional study which focused on knowledge empowerment and behavior change among expecting couples was both feasible and effective on improving knowledge about birth preparedness and complication readiness in rural settings of Tanzania.
