    Development and validation of instrument for assessing patients’ knowledge, attitude, and practice (KAP) on uncomplicated malaria management

    Objectives: To develop and validate patients’ knowledge, attitudes, and practice instrument for uncomplicated malaria (PKAPIUM). Material and Methods: A draft PKAPIUM scale was developed after the review of relevant literature and malaria treatment guidelines, and six experts validated its content. Monte Carlo simulation principle was followed in arriving at 300 patients populations whose data were used to reduce the items based on “Kaiser’s eigenevalue-greater-than-one rule.” This was followed by the test of validity and reliability to assess the psychometric properties of the instrument. Results: The items content validity indices (I-CVI) and the scale CVI (S-CVI) using universal agreement (UA) within experts (S-CVI/UA) and average CVI (S-CVI/Ave) approaches were good (0.8–1.00), with absence of items’ floor or ceiling effects. Twenty-one items were retained in the new scale arranged under four factors with average varianc extracted (AVE) and square root AVE values of 0.58–0.70 and 0.76–0.84, respectively, suggesting convergent and discriminant validities. The goodness-of-fit results [Chi-square (CMIN/DF) = 3.07, p = 0.00], standardized root mean square residual = 0.070, root mean square error approximation = 0.08 confirmed the hypothesized factor structures of the scale whose internal consistency of Cronbach’s alpha and composite reliability values were 0.74 and 0.82, respectively, and stability of ICC = 0.92 [95% confidence interval : 0.87–0.95, F = 43 (p = 0.51)].Conclusion: The validity and reliability of the PKAPIUM were in acceptable ranges.

    Psychometric Classical Theory Test and Item Response Theory Validation of Patients’ Knowledge, Attitudes and Practices of Uncomplicated Malaria Instrument
    (J Young Pharm, 2019-02-14) Jimam Nanloh S.; Ahmad Sohail; Ismail Nahlah Elkudssiah
    Objective: To develop and validate Patients’ Knowledge, Attitudes and Practices Instrument for Uncomplicated Malaria (PKAPIUM) through Classical Test Theory (CTT) complemented by Items Response Theory (IRT). Methods: A draft 31-items’ scale was developed using relevant variables from literature and initially screened by six experts before it was used to collect data from 300 patients receiving treatment for uncomplicated malaria in Primary Health Care (PHC) facilities in Plateau state, Nigeria. An orchestrated classical and modern psychometric approach including CTT and IRT was then used to validate the draft instrument through IBM® Statistical Package for Social Sciences (SPSS®) version 23 and Analysis of Moment Structures (AMOS™) software version 22 and Bond and Fox software®, respectively. Results: The 31-items’ draft scale showed good Item’s Content Validity Index (I-CVI) (> 0.8) with good Universal Agreement (UA) level of Scale Content Validity Index (S-CVI/UA) (0.9 – 1) and average CVI (S-CVI/Ave) (0.98 – 1). The CTT and Rasch analyses resulted in retention of twenty one items distributed under Knowledge, Attitude and Practice(KAP) constructs, with Average Variance Extracted (AVE), square root AVE,chi-square, Standardized Root Mean square Residual (SRMR), Root Mean Square Error Approximation (RMSEA), items’ infit Mean Square (MNSQ), Infit Standardized Z-scores (infit Zstds), Point-Measure Correlation Coefficients (PTMEA Corr), Cronbach’s alpha, items’ and person’s reliability indices within accepted limits. Conclusion: The new scale was considered valid and reliable for assessing patients’ knowledge, attitudes and practiceson uncomplicated malaria.
