3.1 Sample Description
Of the 135 CHWs, most were male (69.3%), had a secondary or higher education level (55.6%), were Christian (70.4%), and either primarily unemployed (43.7%) or a farmer (23.0%). The average age was 38 years. (SD = 13.01; Table 1).
3.2 Internal Consistency of Knowledge, Attitudes, Practices Regarding Epilepsy Subscales and Items with Low Item Rest Correlation
The internal consistency of the subscale Practices During Crisis was low (α = 0.238). The internal consistency was moderate for 2 subscales (Causes of Epilepsy, α = 0.65; Medical Treatment, α = 0.694), acceptable for Cultural Treatment (α = 0.797) and excellent for Safety and Risks (α = 0.926) and Negative Attitudes (α = 0.904). The overall ordinal alpha was not reported because the adapted questionnaire of knowledge, attitudes and practices is a multidimensional scale. Several subscales contained item(s) that were not strongly correlated with other items in the subscale, suggesting that they may be less informative or specific to the subscale construct(26); (Table 3).
To examine the fit of the 6-factor model of knowledge, attitudes, and practices, we conducted a confirmatory factor analysis. The fit of the original model was poor (RMSEA = 0.075, 90% CI: 0.069, 0.081; CFI = 0.582; TLI = 0.553; SRMR = 0.103), primarily due to the multidimensionality of the subscale practices during crisis. The first three items (We Should Put a Stick in the Mouth of the PWE During Seizures; We Should Give a Drink to the PWE During Seizures; We Should Stay Away from PWE During Seizures) most strongly loaded on the first factor, now referred to as Practices of Sticking into a Mouth, Give a Drink, Stay Away. The last three items (We Should Hold PWE During Seizures to Stop Seizures; We Must Help PWE During the Seizures Not to Hit the Head on the Ground; We Must Place the PWE in the Right Lateral Safety Position to Avoid Aspiration) most strongly loaded on the second factor, now referred to as Practices of Holding, Helping, Placing in Safety Position. Dividing the practices during crisis subscale into two factors and estimating the covariance of highly correlated items improved the model to displaying adequate fit (RMSEA = 0.059, 90% CI: 0.051, 0.066; CFI = 0.749; TLI = 0.727; SRMS = 0.098). The item, “we should stay away from PWE during seizures”, from the added “Sticking into a Mouth, Give a Drink, and Staying Away” during crisis subscale loaded slightly more strongly on the Negative Attitudes subscale. Although allowing cross-loading of this item onto both the “Sticking into a Mouth, Give a Drink, and Staying Away” during crisis and the Negative Attitudes subscale would have slightly improved the fit, the benefits were not substantial and may not offset the complexity introduced to scoring the QKAP-EPI and deviating from the original item domains.
3.3 CHWs Responses to the Adapted Questionnaire of Knowledge, Attitudes, Practices Towards Epilepsy
Most of the CHWs very much believed that causes of epilepsy may be related to head injury (59.26%), malaria/meningitis/fever (45.93%), brain injury (54.81%) and is accordingly to the literature, but some did not believe that it can be inherited (52.59%) or related to childbirth injury (54.81%), denoting a lack of knowledge regarding these two items. They also did believe very much that epilepsy can be treated (77.04%) and it should be done in a regular basis to better control the disease (77.78% ), all the conditions of epilepsy with local names (Nzwite, Njiri Njiri) are best treated by a doctor (75.56%; 71.85%), antiepileptic medicines control the seizures (71.85%) and that these medicines can be available in health facilities (88.15%.), demonstrating a positive knowledge regarding the medical treatment of epilepsy.
In the “Cultural Treatment” subscale, a number of CHWs endorsed false cures or treatments for epilepsy. For example, 51% of CHWs believe that if a PWE burns when set on fire, this means this person cannot be cured from epilepsy. Further, 21% believed that during an epileptic crisis, it would be appropriate to put water on the person or make the person smell some one’s shoes. Lastly, 23% believed that putting a stick in someone’s mouth during a seizure can treat epilepsy. More than half of CHWs believed that some forms of epilepsy with local names (Dzumba) can be treated while other forms (Nzwiti) cannot be treated (52.59%) demonstrating a negative knowledge of cultural treatment and the different interpretation of the different names of epilepsy when related to treatment. It was also found that more than half of the CHWs believe that legs of a PWE should be stretched during seizures (52.59%) which goes against the epilepsy treatment protocol.
In the Safety and Risks subscale, more than half of the CHWs believed very much that PWE should: not climb trees (74.04%), not drive (70.37%), avoid fire (85.19%) or water sites (79.26%), which demonstrates positive knowledge, attitudes and practices towards epilepsy in safety and risks. More than half of the CHWs demonstrated low levels of negative attitudes and did believed that PWE should: get married (65.93%), go to school (71.85%) or have a job (74.04%).
Most of the CHWs did not believe that one should put a stick in people's mouths (73.33%), give a drink (78.52%), stay away (71.11%) from PWE during crises, demonstrating a positive knowledge. However, more than half of CHWs believed that we should hold people during seizures to stop them (67.7%) which goes against the epilepsy treatment protocols. (Table 2)
3.4 Average of subscales and Correlation Between Subscales of the Adapted Questionnaire of Knowledges, Attitudes and Practices Towards Epilepsy
The average of subscales, which ranged from 0 (no knowledge) to 2 (good knowledge), were adequate for the following subscales: Medical Treatment (M = 1.63, SD = 0.28), Safety and Risks (M = 1.62, SD = 0.59), Practices of Holding, Helping, and Placing in Safety Position During Crisis (M = 1.60, SD = 0.48). The average of Subscales Causes of Epilepsy (M = 1.10, SD = 0.53), Cultural Treatment (M = 1.48, SD = 0.39), Negative Attitudes (M = 1.47, SD = 0.48), and Practices of Sticking into a Mouth, Give a Drink, Stay Away During Crisis (M = 1.43, SD = 0.42) were slightly lower indicating less knowledge. Correlations between subscales revealed that knowledge about the causes of epilepsy, medical treatment, and sticking into a mouth, giving a drink, and staying away during crisis were not strongly correlated with other subscales (r < 0.250). Knowledge about cultural treatment was moderately correlated with knowledge about negative attitudes toward epilepsy (r = 0.392) and strongly correlated with holding, helping, placing in safety position during crisis (r = 0.575). Safety and risks knowledge were also moderately correlated with negative attitudes (r = 0.319). The holding, helping, and placing in safety position during crisis subscale was weakly correlated with subscale safety and risks (r = 0.204) and negative attitudes (r = 0.254); (Table 04).
3.5 Association Between Demographic Characteristic (Sex, Schooling Level Achieved, Religion, Civil Status) and 6 Subscales of Adapted QKAP Towards Epilepsy
The linear regression revealed differences in knowledge when analyzing by sociodemographic variables. Knowledge about “causes of epilepsy” was higher among the employed relative to those unemployed (b = 0.34, 95% CI: 0.13, 0.56). Knowledge about “cultural treatment” was lower among farmers (b=-0.21, 95% CI: -0.40, -0.01) and those with other primary occupation (b=-0.26, 95% CI: -0.44, -0.09), relative to unemployed CHWs. Knowledge about “medical treatment” was slightly higher among people of older age (b = 0.01, 95% CI: 0.00, 0.01), higher among those in a common law marriage (b = 0.16, 95% CI: 0.03, 0.28), or who were divorced (b = 0.32, 95% CI: 0.02, 0.63), compared to single. The knowledge about “safety and risks” was lower among divorced (b=-1.85, 95% CI: -2.55, -1.15) relative to single CHWs. Knowledge about “Sticking into a Mouth, Give a Drink, and Staying Away During Crisis” was lower among females (vs. males; b=-0.45, 95% CI: -0.70, -0.20). In general, there was a difference in each of the 6 subscale scores when comparing the different nine districts. Total score across all subscales on the QKAP-EPI was significantly higher in Maringue relative to Caia district (b = 0.27, 95% CI: 0.03, 0.52), but did not differ by any other sociodemographic factors (Table 05).
