METHODS: Three hundred patients treated for uncomplicated malaria in selected primary healthcare facilities of Plateau state, Nigeria, completed the EQ-5D-5L scale. Classical test theory was used to establish validity and Cronbach's alpha reliability of the scale. Rasch analysis was used to confirm the unidimensionality, item fitness, item and person separations and reliabilities, and targeting of item difficulty to patient ability levels and presentation on Wright map (item-person map).

RESULTS: The outcome of classical test theory revealed unidimensional scale with average variance extracted values > 0.5, and the square root of the average variance extracted for construct was greater than the correlation coefficients, indicating convergent and discriminant validities of the scale whose Cronbach's alpha coefficient (α) was 0.87. Rasch analysis indicated variance explained values of 88.3% and the eigenvalues of the first contrast was 1.3, further confirming the unidimensionality of the scale, whose fit index values were within accepted ranges. The high item and person separation and reliability values indicated the instrument's strength in detecting and evenly spreading items and persons on the Wright map based on item difficulty and the respondents' ability levels, respectively.

METHODS: A household-based cross-sectional study was conducted in five remote villages (clusters) of Orang Asli located in the State of Kelantan, a central region of the country. Community members aged six years and above were interviewed. Demographic, socio-economic and KAP data on malaria were collected using a structured questionnaire and analysed using descriptive statistics.

RESULTS: Overall, 536 individuals from 208 households were interviewed. Household indoor residual spraying (IRS) coverage and bed net ownership were 100% and 89.2%, respectively. A majority of respondents used mosquito bed nets every night (95.1%), but only 50.2% were aware that bed nets were used to prevent malaria. Nevertheless, almost all of the respondents (97.9%) were aware that malaria is transmitted by mosquitoes. Regarding practice for managing malaria, the most common practice adopted by the respondents was seeking treatment at the health facilities (70.9%), followed by self-purchase of medication from a local shop (12.7%), seeking treatment from a traditional healer (10.5%) and self-healing (5.9%). Concerning potential zoonotic malaria, about half of the respondents (47.2%) reported seeing monkeys from their houses and 20.1% reported entering nearby forests within the last 6 months.

METHODS: This was a randomized controlled parallel-group trial in which 372 antenatal care attendees were randomly assigned to either an intervention or control group after collecting baseline data using a structured questionnaire. The intervention group received a 4-h health education on malaria, guided by a module developed based on the IMB theory, while the control group received health education on breastfeeding for a similar duration and by the same facilitator. Follow-up data were subsequently collected at 2 months and at 4 months post-intervention using the same questionnaire. The generalized linear mixed models analysis was used to determine the between-group and within-group effects of the intervention. The intention-to-treat analysis was used after missing data had been replaced. This was followed by a sensitivity analysis, where the analyses were repeated without replacing the missing values.
