Thisissueisparticularlysalientforchildrenwithseizuredisorders,who relyontheirparentstotakeanti-convulsantmedication(s). Depressivesymptomatology andmaternalstresshavebeenassociatedwithnegativechildstatus. Maternalemotional factorssuchasdepressionandstressmayplayanimportantroleinadherenceto medicationforyoungerchildrenwithepilepsy. Inthecurrentstudy,weexaminedthe relationshipbetweenmaternaladherencetomedication(pillcountpercentage)andchild healthstatus(seizurefrequency,seizure-relatedemergencyroomvisits)forchildrenwith epilepsyandthefollowingfactors:maternalemotionaldistress(maternaldepression, maternalstress),demographics(familyannualincome,race,maternaleducationallevel), condition-relatedandregimen-relatedvariables(diseasetype,diseaseduration,typeand vn complexityofthemedicationregimen,concordancebetweenprescribedregimenand reportedregimen),andmaternalperceptionsofthetreatmentregimen(perceived efficacy,perceivedknowledge,perceiveddifficulty). Researchparticipantsincludedchildren,agesonethrougheleven,diagnosedwith epilepsyandwereapproachedforstudyparticipationattheUniversityofFlorida PediatricNeurologyClinic. Eighty-twomother-childdyadscompletedthestudy. Resultsindicatedthatasmaternalstress,parent-childdysfunction,andmaternal perceivedregimendifficultyincreased,childseizurefrequencysignificantlyincreased. Asmaternalperceivedregimenefficacylevelsincreased,childseizurefrequency significantlydecreased. Resultsrevealedthatasmaternalperceivedregimendifficulty levelsincreased,seizure-relatedemergencyroom(ER)visitssignificantlyincreased. As regimenconcordanceratesincreased,seizure-relatedERvisitssignificantlydecreased. Resultsdemonstratedthatasconcordanceratesincreased,pillcountincreased. Finalhierarchicalregressionanalysessuggestedthatparent-childdysfunctionwas predictiveofseizurefrequency. Maternalperceivedregimendifficultyratingsand concordanceratingsbetweentheprescribedandreportedregimenwerepredictiveof seizure-relatedERvisits.
