wFactors other than social capital
Since the study was conducted in Sepon district only, we
assumed that the effects of other parts of contributors
such as the supervisory system and the structure of the
financial incentive [9] were similar among the VHVs
who participated in our study. However, another variable,
“number of training sessions attended”, was also
significantly associated with VHV performance in the
bivariate logistic regression analysis. Although it may
infer reverse causation, other study has also reported
that the adequate training programs for CHWs improve
their performance [29]. Therefore, we are aware that
other factors might have affected on VHV performance
as well as social capital. Also, we believe that social capital
and other non-monetary incentives deserve more attention
in terms of the sustainability and feasibility of
the program
