Reliability and validity of the Malay-version Chicago lead knowledge test (CLKT) among parents of preschool children in Malaysia
The primary objective of this study was to validate the Malay-version Chicago lead knowledge test (CLKT). The CLKT was chosen based on thorough literature review followed by a systematic translation. Data collection involved three phases; initial test was done among 70 parents, retest was done...

The primary objective of this study was to validate the Malay-version Chicago
lead knowledge test (CLKT). The CLKT was chosen based on thorough literature
review followed by a systematic translation. Data collection involved three phases;
initial test was done among 70 parents, retest was done at two weeks apart among
similar respondents with response rate of 71.4% (n=50), and another test among 60
professional group. The authors performed non-parametric tests since the data was
not normally distributed. The non-parametric test results showed no significant
mean knowledge score differences in all demographic parameters. The difficulty
factor ranged from 0.01 to 0.99. The mean + SD for difficulty factor was 0.52 +
0.32. Half of the 24 items (n=12) had a difficulty factor of less than 0.75. Only
one item (item 6) had item-total correlation of less than 0.2 (0.140). The overall
Cronbach’s α coefficient was 0.851. No significant difference was detected by the
Wilcoxon Signed-Rank Test between the overall score, the test and retest scores
for all domains. All domains showed moderate to strong correlation (Spearman’s
Correlation: r=0.546 - 0.814, p<0.001). The Mann-Whitney U test showed a
significantly higher knowledge score in professional group compared to parent
group for all domains and total knowledge score (p<0.001). The Malay-version
CLKT was moderately difficult but had a good reliability and validity. Thus, this
instrument can be applied in future larger-scale study. |
