OBJECTIVES: The aim of this paper was to describe the development and psychometric evaluation of new Epilepsy Disclosure Scales (EDSs) for youths with epilepsy (YWE) and their parents.

METHODS: Developing the EDSs for youths and parents comprised a number of stages, including questionnaire construction and item development for the new EDSs (consisting of a pilot and review of the newly developed EDSs) and psychometric evaluation of the measures to assess their appropriateness, factor structure, reliability, and validity. Psychometric properties were determined using a cross-sectional survey of 47 YWE and 72 parents.

RESULTS: Two scales were developed to assess the epilepsy disclosure behaviors of YWE and their parents; that is, the extent to which they tell and talk to others about the child's epilepsy. The youth version of the EDS comprised six items and had a unidimensional factor structure that explained 55% of the variance. The parent version of the EDS also consisted of six items, with a single factor explaining 47% of the variance. The suitability, validity, and reliability of the youth and parent versions of EDSs were supported by positive indicators, such as a high Cronbach's alpha (representative of good internal consistency) and the confirmation of a number of hypothesized relationships between epilepsy disclosure and psychosocial and illness attitude variables (demonstrative of their convergent validity).

CONCLUSION: Prior to the development of these instruments, no valid and reliable measures existed that could suitably capture disclosure amongst populations living with epilepsy. The youth and parent versions of the EDS are valid, reliable, brief, and easily administered and thus could prove useful in research as well as in the clinical setting. These scales will enable researchers and clinicians to profile the epilepsy disclosure behaviors of YWE and their parents, which play an important role and have implications both for the psychosocial wellbeing of families living with epilepsy and for epilepsy-related stigma.
