Abstract
Purpose: To establish knowledge retention
(KR) baseline levels from the entry training
community health promoters (CHPs)
received in diverse years since 2006 in
Nyandarua County, Kenya. Moreover, to
determine the influence of spaced repetition
(SR) intervention on knowledge retention.
Materials and Methods: Quasi
experimental design through pre and post
intervention tests were used and the sample
(n=348) was calculated through Yamane
(1967) formula at 95% confidence interval.
Tests’ measured KR and the use of mobile
phone short message service (SMS)
happened to the respondents once per week
in 12 weeks after the pre intervention and
before the post intervention test. The 4 key
messages from the CHP training manual
were relayed interchangeably, each 3 times
in total. Both tests used competence based
curriculum (CBC) rubrics; exceeding
expectation (EE), approaching expectation
(AE), meeting expectation (ME) and below
expectation (BE).
Findings: With a response rate of 92% (n=
320), at pre intervention 82.2% (n=263) had
BE KR which is 0-49% score and only
0.6% (n=2) had EE with a mean of 1.21
(30.25%) out of scale of 4. At post
intervention the mean was 2.49 (62.25%),
an improvement ratio of 2.1. The BE fell to
35.3% (n=113) and EE increased to 33.4%
(n=107) at post intervention. SR was
statistically significant on knowledge
retention according to the Wilcoxon signed
rank test results (Z = -11.919, p = 0.000).
Implications to Theory, Practice and
Policy: Results confirmed the multi-store
memory theory that some knowledge
‘decays’ before entering the long term
memory but on several reminders
knowledge can resurface; a further
confirmation of the forgetting curve that
information is forgotten over time if not
reviewed. Results mean that training CHPs
once without subsequent knowledge
reinforcement may have less significant
effects. Going forward, county government
of Nyandarua should organize periodical
training refreshment programs for CHPs
