BACKGROUND: @entity1 's knowledge on @entity6 , @entity101 and hyperlipidaemia and its medications can be used as one of the outcome measures to assess the effectiveness of educational intervention. To date, no such instrument has been validated in Malaysia. Therefore, the aim of this study was to evaluate the validity and reliability of the @entity101 ( @entity101 ) knowledge instrument for assessing the knowledge of @entity1 with @entity164 2 @entity6 in Malaysia. METHODS: A 28-item instrument which comprised of 5 domains: @entity6 , @entity101 , @entity407 , medications and general issues was designed and tested. One point was given for every correct answer, whilst zero was given for incorrect answers. Scores ranged from 0 to 28, which were then converted into percentage. This was administered to 77 @entity1 with @entity164 2 @entity6 in a tertiary hospital, who were on medication(s) for @entity6 and who could understand English ( @entity1 group), and to 40 pharmacists (professional group). The @entity101 knowledge instrument was administered again to the @entity1 group after one month. Excluded were @entity1 less than 18 years old. RESULTS: Flesch reading ease was 60, which is satisfactory, while the mean difficulty factor(SD) was 0.74(0.21), indicating that @entity101 knowledge instrument was moderately easy. Internal consistency of the instrument was good, with Cronbach's a = 0.791. The test-retest scores showed no significant difference for 26 out of the 28 items, indicating that the questionnaire has achieved stable reliability. The overall mean(SD) knowledge scores was significantly different between the @entity1 and professional groups [74.35(14.88) versus 93.84(6.47), p < 0.001]. This means that the @entity101 knowledge instrument could differentiate the knowledge levels of @entity1 . The @entity101 knowledge instrument shows similar psychometric properties as other validated questionnaires. CONCLUSIONS: The @entity101 knowledge instrument shows good promise to be adopted as an instrument for assessing @entity6 @entity1 ' knowledge concerning their disease conditions and medications in Malaysia.

Validation of the @entity6 , @entity101 and @entity407 ( XXXX ) knowledge instrument in Malaysia.
