Does Epilepsy Have an Impact on Locus of Control?

Feasibility and acceptability of an online epilepsy stigma self-management program

INTRODUCTION

Stigma is a prevalent source of distress in people with epilepsy. We developed a self-paced online stigma self-management program for adults with epilepsy (Reducing Internalized Stigma in Epilepsy: A Behavioral Online Video Education, RISE ABOVETM).

MATERIALS AND METHODS

Twenty socio-demographically diverse participants completed RISE ABOVE over an average of 3.5 weeks. Acceptability was determined by whether ≥ 80 % responded favorably to the Credibility and Expectancy Questionnaire and tailored surveys. Treatment Satisfaction was determined by whether mean Client Satisfaction Questionnaire responses was ≥ 80 %. Epilepsy Stigma, Perceived Stress, Perceived Rejection, Loneliness, Self-Efficacy, and Satisfaction with Social Roles and Activities were rated pre-post-intervention. Paired sample t-tests and Hedges' g effect sizes gauged improvements.

RESULTS

Most participants (≥ 80 %) thought the intervention was logical and content was easy to understand/navigate, interesting/helpful, and planned on using learned skills. Mean satisfaction was 85.41 % ± 14.43 %. There were large improvements in Epilepsy Stigma (p < 0.001; Hedge's g = 1.052), Perceived Stress (p < 0.001; Hedge's g = 0.887) and Satisfaction with Social Roles and Activities (p < 0.001; Hedge's g = -1.010), and medium improvements in Perceived Rejection (p = 0.004; Hedge's g = 0.634) and Self-Efficacy (p = 0.008; Hedge's g = -0.568). No significant differences were observed 6-months post-program completion, despite some attenuation.

CONCLUSIONS

RISE ABOVE is a feasible and acceptable anti-stigma intervention. Markers of acceptability were evident in high rates of credibility and satisfaction. Sizable improvements in stigma and other psychosocial outcomes were seen. Future studies will establish RISE ABOVE's efficacy via a randomized controlled trial.

Impact of interaction among antiseizure medication polytherapy, clinical, sociodemographic and psychological factors on quality of life in patients with epilepsy: A systematic review

INTRODUCTION

Drug-resistant epilepsy usually requires the use of polytherapy with antiseizure medications (ASMs) for management, which could involve side and adverse effects that may impact quality of life (QOL). This systematic review summarizes the evidence about the relationship between ASM polytherapy and QOL in epilepsy patients, considering clinical, sociodemographic, and psychological variables.

METHOD

This review followed the PRISMA guidelines and was registered in PROSPERO. The studies examined were collected from PubMed/MEDLINE, Scopus, Web of Science, and Embase. The data extracted were categorized into three categories: therelationship between the number of ASMs and QOL, differences in QOL between patients taking polytherapy and patients taking monotherapy, and therole of other variables on QOL.

RESULTS

The review included 34 studies. Thirty examined the relationship between the number of ASMs and QOL, 93.3% of them identifying a significant association between a higher number of ASMs and poorer QOL. Fifteen studies analyzed differences in QOL between patients receiving polytherapy and those on monotherapy, all of them showing poorer QOL in those on polytherapy. Thirty-two studies considered other factors beyond polytherapy as determinants of QOL, including clinical, sociodemographic, and psychological variables, and higher seizure frequency and mood comorbidities (depression and anxiety) emerged as the strongest predictors of poor QOL.

CONCLUSIONS

Polytherapy, despite being necessary for managing drug-resistant epilepsy, significantly contributes to impairing QOL. Effective seizure control remains critical, but a multifactorial approach addressing mental health and social determinants is essential for improving QOL in epilepsy patients. Future research should focus on optimizing treatment strategies that balance seizure control by minimizing the negative impact of polytherapy.

Romanian Translation and Cultural Adaptation of the Seizure Severity Questionnaire

The aim of this study was to report the translation into Romanian of the Seizure Severity Questionnaire (SSQ), an instrument for the evaluation of the frequency and severity of epileptic seizures, and the results of applying it to a group of patients with epilepsy evaluated at a hospital in Romania.

METHODS

Four translators were involved in obtaining conceptual analogies and the cultural importance of the translated notions. The final version was obtained for the Romanian population, with the same appearance as the original instrument. Sixty-seven patients with epilepsy completed the SSQ and the Patient-Weighted Quality of Life in Epilepsy Inventory-QOLIE-31-P.

RESULTS

Females had a lower mean SSQ total score (TS) and perceived seizures less seriously than men. Patients with epilepsy with aura had a higher mean SSQ TS, with a more severe seizure perception, compared to those without aura. According to the frequency of seizures, patients with epilepsy with rare seizures had the lowest mean SSQ total score (TS) compared to those with frequent seizures. Patients who were on monotherapy had a less severe perception of epileptic seizures compared to those who were treated with two or more antiepileptic drugs. All QOLIE-31-P domains and TS correlated statistically significantly with the SSQ TS.

CONCLUSIONS

This study explored SSQ translation, evaluated preliminary results, and showed the correlation between seizure frequency and severity, clinical factors, and quality of life. This tool could be useful for measuring seizure severity in Romanian patients with epilepsy and conducting comparative studies.

User experience of a seizure risk forecasting app: A mixed methods investigation

OBJECTIVE

Over recent years, there has been a growing interest in exploring the utility of seizure risk forecasting, particularly how it could improve quality of life for people living with epilepsy. This study reports on user experiences and perspectives of a seizure risk forecaster app, as well as the potential impact on mood and adjustment to epilepsy.

METHODS

Active app users were asked to complete a survey (baseline and 3-month follow-up) to assess perspectives on the forecast feature as well as mood and adjustment. Post-hoc, nine neutral forecast users (neither agreed nor disagreed it was useful) completed semi-structured interviews, to gain further insight into their perspectives of epilepsy management and seizure forecasting. Non-parametric statistical tests and inductive thematic analyses were used to analyse the quantitative and qualitative data, respectively.

RESULTS

Surveys were completed by 111 users. Responders consisted of "app users" (n = 58), and "app and forecast users" (n = 53). Of the "app and forecast users", 40 % believed the forecast was accurate enough to be useful in monitoring for seizure risk, and 60 % adopted it for purposes like scheduling activities and helping mental state. Feeling more in control was the most common response to both high and low risk forecasted states. In-depth interviews revealed five broad themes, of which 'frustrations with lack of direction' (regarding their current epilepsy management approach), 'benefits of increased self-knowledge' and 'current and anticipated usefulness of forecasting' were the most common.

SIGNIFICANCE

Preliminary results suggest that seizure risk forecasting can be a useful tool for people with epilepsy to make lifestyle changes, such as scheduling daily events, and experience greater feelings of control. These improvements may be attributed, at least partly, to the improvements in self-knowledge experienced through forecast use.

How do children with focal epilepsies perceive the moment they realize that they are about to have a seizure? A pilot study

PROBLEM

A seizure is a challenging situation for children with epilepsy. Little is known regarding the experience of children who perceive in advance that they are about to have a seizure.

METHODS

From September 2020 to February 2021, we invited children with focal epilepsies aged 6-18 years to participate in a semi-structured interview.

RESULTS

Of 52 children with focal epilepsies, 22 (42 %) said they perceive in advance that they are about to experience a seizure [11 with self-limited epilepsy with centro-temporal spikes (SELECTs), 11 with other focal epilepsies]. All 22/22 (100 %) children described physical symptoms such as headache or a numb feeling in one half of the body. Of those children, 17/22 (77 %) stated they try to do something about the seizure. Those strategies were perceived as helpful by 0/11 (0 %) children with SELECTs and 9/11 (86 %) children with other focal epilepsies (p < 0.001). Of the children with SELECTs 5/11 (45 %), and of those with other focal epilepsies 9/11 (86 %) stated they would like to know in the morning if they are to experience a seizure that day (n.s.).

CONCLUSION

Children who perceive in advance that they are about to have a seizure are well able to describe their experience. Most children take measures to manage their seizures. Those measures were regarded as helpful by most children with other focal epilepsies, but by no child with SELECTs. Larger studies are necessary to determine the factors contributing to the child's perception as well as the nature of the support that they require.

Felt stigma may potentiate the relationship between perceived stress and depressive symptoms in persons with epilepsy

PURPOSE

This study assessed the strengths of association among perceived stress, felt stigma, and depression in adults with epilepsy, and evaluated whether felt stigma altered the association between perceived stress and depression.

METHODS

This multicenter, cross-sectional study included adults with epilepsy. Depression was assessed using the Beck Depression Inventory (BDI), and perceived stress was evaluated using the 10-item Perceived Stress Scale. Felt stigma was determined using the three-item Stigma Scale for Epilepsy, with individuals categorized as positive for felt stigma if they answered "yes" to at least one of these items. A hierarchical linear regression analysis and an analysis of covariance with interaction terms were performed.

RESULTS

The 316 adults with epilepsy included 171 men and 145 women; of these, 109 (34.5%) reported felt stigma. A hierarchical linear regression analysis showed that perceived stress was the most important correlate of depressive symptoms, followed by felt stigma, being unemployed, recurrence of generalized or focal to bilateral tonic-clonic seizures, and being married. The model explained 54.0% of the variance of BDI scores. Significant interactions between felt stigma and perceived stress on BDI scores was identified in both crude and adjusted models (p < 0.05 each). Specifically, in an adjusted model, BDI scores were more strongly associated with perceived stress in persons with (p < 0.001, partial eta² = 0.225) than without (p < 0.001, partial eta² = 0.205) felt stigma.

CONCLUSIONS

Perceived stress was the most significant correlate of depressive symptoms in adults with epilepsy, followed by felt stigma. The interaction between perceived stress and felt stigma on depressive symptoms was significant. These findings may help in developing cognitive behavioral therapy for stigma and stress management in persons with epilepsy.

Nonpharmacologic Interventions and Seizure Frequency in Patients With Psychogenic Nonepileptic Seizures: An Integrative Review

BACKGROUND

Psychogenic nonepileptic seizures (PNES) pose a heavy burden on patients' lives and the health care system. The symptoms of PNES are often debilitating and cause high rates of disability and poor quality of life. Many treatment options are available, but there is no clear consensus on best practices.

AIM

To critique and synthesize the current literature on nonpharmacologic interventions and effects on seizure frequency in patients with PNES.

METHODS

An integrative review guided by the Whittemore and Knafl approach.

RESULTS

The review included 24 studies published from 2010 to 2020. Interventions for PNES included individualized psychotherapies, group therapies, multimodal psychotherapies, self-help therapies, and complementary and alternative medicine therapies. Individual psychotherapies such as cognitive behavioral therapy and psychoeducation were the most used treatment modalities. The most effective treatments for seizure frequency reduction were those that included multiple psychotherapy sessions with a health care provider and covered multiple domains (e.g., understanding of diagnosis, identifying triggers, and developing effective coping strategies).

CONCLUSIONS

Seizure frequency can be reduced in patients with PNES with multiple nonpharmacologic interventions. However, seizure frequency is not considered a comprehensive outcome measure and provides little insight into other important life domains. Further research is needed on nonpharmacologic interventions for PNES and effects on other areas of life such as sleep, employment status, global functioning, and self-efficacy.

Quality of Life in Epilepsy: Same questions, but different meaning to different people

OBJECTIVES

Patient-reported outcome measures (PROMs) are used widely to elicit patient's self-appraisal of their health status and quality of life. One fundamental assumption when measuring PROMs is that all individuals interpret questions about their health status in a consistent manner. However, subgroups of patients with a similar health condition may respond differently to PROM questions (ie, differential item functioning [DIF]), leading to biased estimates of group differences on PROM scores. Understanding these differences can help inform the clinical interpretation of PROMs. This study examined whether DIF affects 10-item Quality of Life in Epilepsy (QOLIE10) scores reported by patients with epilepsy in outpatient clinics.

METHODS

Data were from the Calgary Comprehensive Epilepsy Program, a prospective registry of patients with epilepsy in Calgary, Alberta. Latent variable mixture models (LVMMs) based on standard two-parameter graded response models with increasing numbers of latent classes were applied to QOLIE10 item data. Model fit was assessed using the Bayesian Information Criterion (BIC) and latent class model entropy. Ordinal logistic regression was used to identify QOLIE10 items that exhibited DIF.

RESULTS

In this cohort of 1143 patients, 567 (49.6%) were female and the median age was 37.0 (interquartile range [IQR] 27.0) years. A two-class LVMM, which provided the best fit to the data, identified two subgroups of patients with different response patterns to QOLIE10 items, with class proportions of 0.62 and 0.38. The two subgroups differed with respect to antiseizure polytherapy, reported medication side effects, frequency of seizures, and psychiatric comorbidities. QOLIE10 items on the physical and psychological side effects of medication exhibited large DIF effects.

SIGNIFICANCE

Our study revealed two different response patterns to quality-of-life instruments, suggesting heterogeneity in how patients interpret some of the questions. Researchers and users of PROMs in epilepsy need to consider the differential interpretation of items for various instruments to ensure valid understanding and comparisons of PROM scores.
