ABSTRACT: Objective
To develop and validate a measure of antiepileptic drug (AED) side effects in children with a variety of seizure types, treatments, and therapy durations.Methods
Content for an initial 44-item measure was developed using the previously published Hague Scale and expert opinion from recognized pediatric epileptologists (n = 12) and caregivers of children with epilepsy (n = 21). The measure was completed by caregivers during routine clinic visits. Demographic and medical data were collected through chart reviews. Factor analysis was conducted and internal consistency, test-retest reliability, and construct validity were assessed.Results
Questionnaires were analyzed from 495 children with epilepsy (M(age) = 10.1 years; range 2-21 years; 42% female; 14% African American; 32% new onset vs 68% chronic epilepsy). The final questionnaire, the Pediatric Epilepsy Side Effects Questionnaire (PESQ), is a 19-item measure with 5 subscales (i.e., cognitive, motor, behavioral, general neurological, and weight) that accounts for 99% of the variance. Internal consistency coefficients and test-retest reliabilities ranged from 0.72 to 0.93 and 0.74 to 0.97, respectively. Construct validity was demonstrated by increasing side effects as the number of drugs increased. Participants on valproic acid had significantly higher scores on the Weight Scale compared to those on carbamazepine.Conclusions
The PESQ is a reliable and valid measure of AED side effects in children across the epilepsy spectrum that can be used in both clinical and research settings.

Project description:Epilepsy, particularly in older people, is associated with significant changes in physical activities, social and occupational functions, and diet. It is associated with significant changes in physical activities, social and occupational functions, and diet. Valid and reliable instruments are needed to assess these changes. This study aimed to develop and validate a questionnaire to assess lifestyle in older people with epilepsy, named the Epilepsy Lifestyle Questionnaire (ELQ). This methodological study was conducted in 2022. The primary ELQ items were generated through reviewing the literature. Then, its face, content, construct, convergent, and discriminant validity, internal consistency, and test-retest stability were evaluated. Older patients aged ≥ 60 years were recruited from the Iranian Epilepsy Association to assess construct validity using confirmatory factor analysis (CFA). Data were analyzed using the SPSS (v. 26.0), AMOS (v. 24.0), and JASP software. The primary ELQ had 99 items with five subscales, namely health-oriented self-care, risk-averse behavior, emotional and psychosocial adaptation, epilepsy stigma, and intimacy and sexual behaviors. Sixty five items were deleted during psychometric evaluation. CFA showed the good fitting of the five-factor structure of the 34-item ELEQ (PCFI = 0.741, PNFI = 0.693, CMIN/DF = 0.073, IFI = 0.917, CFI = 0.916, AND GFI = 0.902). The values of internal consistency based on Cronbach's alpha and test-retest reliability based on intraclass correlation coefficient (ICC) of ELQ were 0.89 and 0.95, respectively. The ELQ is a valid and reliable self-report instrument. The results suggest that the ELQ is a useful clinical tool for assessing the lifestyle of patients with epilepsy.

Project description:We developed the Recurrence and Recovery Questionnaire (RRQ) by converting the Pediatric Stroke Outcome Measure (PSOM) to a questionnaire for telephone interview and sought to validate the RRQ in a large cohort.We analyzed parents' RRQ responses and same-day PSOM assessments for 232 children who had arterial ischemic stroke, cerebral sinovenous thrombosis, or presumed perinatal ischemic stroke. We assessed the agreement and consistency of the PSOM and RRQ, and we identified conditions that contributed to differences between the 2 measures. We tested selected factors as predictors of differences between the total PSOM and total RRQ (tPSOM and tRRQ) scores.Median PSOM score was 1.5 and median RRQ score was 1.5. There was good agreement between tPSOM and tRRQ, and RRQ was a reliable estimator of PSOM at the total and component level. Preexisting neurologic deficits or chronic illnesses increased the difference between the tPSOM and tRRQ; the chronic illness effect was confirmed with univariate analysis.The RRQ can characterize poststroke function when a child cannot return for examination. While the RRQ is not identical to the PSOM, the 2 measures likely assess closely related aspects of recovery. The RRQ is particularly useful when assessing outcomes of large cohorts, and will be useful in performing long-term follow-up studies of pediatric stroke.

Project description:At a fundamental level, taxonomy of behavior and behavioral tendencies can be described in terms of approach, avoid, or equivocate (i.e., neither approach nor avoid). While there are numerous theories of personality, temperament, and character, few seem to take advantage of parsimonious taxonomy. The present study sought to implement this taxonomy by creating a questionnaire based on a categorization of behavioral temperaments/tendencies first identified in Buddhist accounts over fifteen hundred years ago. Items were developed using historical and contemporary texts of the behavioral temperaments, described as "Greedy/Faithful", "Aversive/Discerning", and "Deluded/Speculative". To both maintain this categorical typology and benefit from the advantageous properties of forced-choice response format (e.g., reduction of response biases), binary pairwise preferences for items were modeled using Latent Class Analysis (LCA). One sample (n1 = 394) was used to estimate the item parameters, and the second sample (n2 = 504) was used to classify the participants using the established parameters and cross-validate the classification against multiple other measures. The cross-validated measure exhibited good nomothetic span (construct-consistent relationships with related measures) that seemed to corroborate the ideas present in the original Buddhist source documents. The final 13-block questionnaire created from the best performing items (the Behavioral Tendencies Questionnaire or BTQ) is a psychometrically valid questionnaire that is historically consistent, based in behavioral tendencies, and promises practical and clinical utility particularly in settings that teach and study meditation practices such as Mindfulness Based Stress Reduction (MBSR).

Project description:BackgroundThe associations between compassion, self-compassion, and body image are well established. However, there is not yet a compassion-informed measure of body compassion that can be applied to any aspect of one's body.MethodItems for The Body Compassion Questionnaire (BCQ) were derived from an earlier expressive writing study on self-compassion in body image. In study 1, the BCQ was completed by 728 men and women; with factor analysis, Rasch analysis, content and concurrent validation and reliability assessed. Study 2 compared BCQ scores with investigator-based ratings of spontaneous expressions of body compassion through writing in female undergraduates as well as an existing measure of body compassion. Study 3 examined the associations between BCQ scores, and the emotions expressed in a structured body image writing task. It also examined the relative predictive ability of the BCQ versus self-compassion in predicting eating pathology.ResultsA bi-factor structure was identified, with an overall BCQ score and three subscales: body kindness, common humanity, and motivated action. The BCQ and its subscales had good validity and reliability and Rasch analysis showed the item fit was invariant across a range of demographic characteristics. Spontaneous expressions of body compassion showed positive associations with body kindness. Overall BCQ scores and body kindness were also inversely related to negative emotions expressed in relation to body image. The BCQ was a better predictor of eating disorder symptoms than was self-compassion.ConclusionsThe BCQ is the first measure of body compassion that is aligned with theoretical aspects of self-compassion, and which includes aspects of both the first and second psychologies of compassion. It also highlights its potential use as a process measure of body compassion in models of eating disorder symptomology, mood and wellbeing as well as an outcome measure for compassion-based interventions in eating disorders and body image.

Project description:ObjectiveInsomnia is a highly prevalent sleep disorder that is particularly common among adolescents with health conditions. We aimed to develop and validate a brief screening measure of insomnia in adolescents that can be used across clinical and community samples. We hypothesized that we would identify evidence supporting reliability, convergent/discriminant validity, and that we would determine preliminary clinical cutoff scores.MethodsA team of experts in behavioral sleep medicine developed a 13-item brief screening measure of insomnia in adolescents (Adolescent Insomnia Questionnaire [AIQ]). We evaluated the psychometric properties of the AIQ in a sample of 315 youth (11-18 years old, Mean = 14.90, SD = 2.02; 64% female) who had chronic pain (n = 37), headache (n = 170), insomnia diagnosed by a sleep specialist (n = 22), or were otherwise healthy (n = 86).ResultsUsing Exploratory and Confirmatory Factor Analysis, we identified three subscales consistent with major diagnostic criteria of insomnia. As expected, the measure showed strong reliability through high internal consistency (α =.91). We also found strong convergent validity through expected positive relationships between the AIQ and self-report measures of sleep disturbance, and divergent validity via weak relationships with parent-report of snoring. Results of receiver operating characteristic (ROC) identified a clinical cutoff score that may assist in clinical decision making.ConclusionsWe found that the AIQ has sound psychometric properties in a large heterogeneous sample of treatment-seeking youth and youth from the community. The AIQ can quickly screen adolescent insomnia and could address an important clinical need in identifying youth in need of insomnia treatment in pediatric practice settings.

Project description:Phenobarbital remains one of the most widely used antiepileptic drugs worldwide, yet there are limited data regarding side effects associated with its use in routine clinical care settings in low-income countries. Available data suggests that phenobarbital is as effective as other first-line drugs for treating tonic-clonic seizures, but side effect reports differ widely between high and low-income settings. A better understanding of phenobarbital side effect profile and severity in low-income settings is warranted given its role in efforts to decrease the epilepsy treatment gap. We used the Liverpool adverse events profile (LEAP) to assess side effects in consecutive patients with epilepsy on phenobarbital seeking care in rural Zambia. Data regarding age, gender, medication dose, and medication adherence were also collected. T-tests and Spearman's correlation coefficient were used to assess predictors of LEAP score and medication adherence. Thirty-five patients receiving a mean dose of 2.1mg/kg/day (SD: 2.78 mg/kg/day) of phenobarbital were assessed. All participants reported at least one side effect in the previous four weeks with a median of 6 symptoms (IQR: 4-8) and a mean side effects score of 28/76 (SD: 5.38). Over half reported sleepiness and dizziness. Memory problems and depression were also common (both 46%). Total LAEP score was not associated with age (p=0.88), gender (p=0.17), or phenobarbital dose (p=0.13). Medication adherence was not associated with side effects total score (p=0.56). Rural Zambian adults taking phenobarbital at doses recommended by the World Health Organization report a significant number of side effects. The most common side effects reported were similar to those reported in high-income countries. The significant burden of phenobarbital-associated side effects in this African cohort is in contrast to data from non-randomized clinical trials in China that reported phenobarbital to be well-tolerated with few side effects. Additional investigations regarding phenobarbital side effects during routine care in low income settings is warranted.

Project description:Objective: To develop and evaluate the validity of a self-report measure of sleep practices for youth 8-17 years. Methods: Following recommended guidelines for the development of patient reported outcomes (PROs), sleep practice concepts were identified through expert (n = 8) and child (n = 28) concept elicitation interviews and a systematic literature review. Items were developed based on these concepts and tested in cognitive interviews with children (n = 32). Psychometric analyses were applied to item response data collected from a diverse sample of youth 8-17 years (n = 307). Construct validity was evaluated through tests of associations between sleep practices and sleep disturbance and sleep-related impairment. Finally, clinical validity of the tool was assessed by comparing scores of youth with and without a parent-identified sleep problem. Results: The final Pediatric Sleep Practices Questionnaire (PSPQ) included 15 items that were used to identify 5 sleep practices: sleep timing, sleep routines and consistency, technology use before bedtime, sleep environment, and the need for parental presence to fall asleep. A confirmatory factor analysis supported the hypothesized structure (all factor loadings ≥ 0.72) and PSPQ indices were significantly associated with self-reported sleep disturbances and sleep-related impairment. Finally, children with parent-reported sleep problems had shorter sleep opportunity, later bedtimes, greater need for parental presence, poorer bedtime routines, and more technology use than children without parent-reported sleep problems. Conclusions: The PSPQ was developed using best-practice PRO development methodology. The PSPQ can be used in clinical settings and for research assessment to capture modifiable sleep practices that may promote or interfere with healthy sleep.

Project description:BACKGROUND:After a mobile health (mHealth) app is created, an important step is to evaluate the usability of the app before it is released to the public. There are multiple ways of conducting a usability study, one of which is collecting target users' feedback with a usability questionnaire. Different groups have used different questionnaires for mHealth app usability evaluation: The commonly used questionnaires are the System Usability Scale (SUS) and Post-Study System Usability Questionnaire (PSSUQ). However, the SUS and PSSUQ were not designed to evaluate the usability of mHealth apps. Self-written questionnaires are also commonly used for evaluation of mHealth app usability but they have not been validated. OBJECTIVE:The goal of this project was to develop and validate a new mHealth app usability questionnaire. METHODS:An mHealth app usability questionnaire (MAUQ) was designed by the research team based on a number of existing questionnaires used in previous mobile app usability studies, especially the well-validated questionnaires. MAUQ, SUS, and PSSUQ were then used to evaluate the usability of two mHealth apps: an interactive mHealth app and a standalone mHealth app. The reliability and validity of the new questionnaire were evaluated. The correlation coefficients among MAUQ, SUS, and PSSUQ were calculated. RESULTS:In this study, 128 study participants provided responses to the questionnaire statements. Psychometric analysis indicated that the MAUQ has three subscales and their internal consistency reliability is high. The relevant subscales correlated well with the subscales of the PSSUQ. The overall scale also strongly correlated with the PSSUQ and SUS. Four versions of the MAUQ were created in relation to the type of app (interactive or standalone) and target user of the app (patient or provider). A website has been created to make it convenient for mHealth app developers to use this new questionnaire in order to assess the usability of their mHealth apps. CONCLUSIONS:The newly created mHealth app usability questionnaire-MAUQ-has the reliability and validity required to assess mHealth app usability.

Project description:Objective:To develop the Military Career Adaptability Questionnaire (MCAQ) in China and to test its reliability and validity. Methods:In study 1, an open-ended questionnaire survey was conducted among 200 military personnel. Based on the empirical construction by military personnel of various branches, the dimensions of the MCAQ were constructed, and a preliminary questionnaire was prepared. In study 2, the questionnaire survey was conducted in 1,578 participants enrolled through stratified cluster sampling. They were randomly divided into two groups (n = 789). Sample 1 was used for item analysis and exploratory factor analysis, and sample 2 was used for confirmatory factor analysis and internal consistency testing. In sample 1, the participants were selected to test the test-retest reliability of the questionnaire at a 4 weeks interval. In sample 2, participants were selected to test criterion validity using the Psychological Capital Questionnaire and the Job Satisfaction Questionnaire. Results:According to study 1, we obtained an initial 23-item MCAQ containing five dimensions (organization and fusion ability, communication ability, learning development ability, emotion regulation ability, and career transformation ability). After the exploratory factor analysis in study 2, 21 items contributing 72.17% of the total variance remained. Via the subsequent confirmatory factor analysis, the model was confirmed to have good fit indices [chi-square/degree of freedom (X 2/df) = 3.11, goodness of fit index (GFI) = 0.90, normed fit index (NFI) = 0.91, incremental fit index (IFI) = 0.94, tucker lewis index (TLI) = 0.93, comparative fit index (CFI) = 0.94, standardized root mean square residual (SRMR) = 0.07]. These five factors were significantly correlated with the total score of the MCAQ (r = 0.73-0.79, p < 0.01). The Cronbach ? coefficient of the questionnaire was 0.92; the Cronbach ? coefficients of the five factors were 0.89, 0.83, 0.88, 0.84, and 0.79, respectively, the test-retest reliability of the questionnaire was 0.93. Conclusion:The MCAQ developed in this study has a clear five-factor structure and good reliability and validity. It can be used to assess the career adaptability of military personnel to provide a theoretical basis for military vocational psychological education.

Project description:Complementary/alternative medicine and integrative medicine (CAM/IM) are increasingly used in the U.S. We set out to develop and validate a brief questionnaire measuring health care provider and medical student attitudes regarding these approaches to healthcare.IMAQ is a 29-item, 7-point Likert scale rated instrument, developed from focus groups consisting of faculty, fellows, visiting residents, and medical students at a university based integrative medicine program. Respondents included 111 (of 574 contacted) internal medicine physicians on an academic medical center CME list and 85 healthcare providers (mostly physicians) attending an American Holistic Medical Association Annual Conference (296 attending). Cohorts were selected for expected differences in attitudes toward CAM/IM.Factor analysis demonstrated that a 2 factor solution best explained the variance in responses (38%). Factor 1 ("openness to new ideas and paradigms") explained 26% of variance with loadings ranging from 0.79 to 0.3, with factor 2 ("value of both introspection and relationship to patient") contributing an additional 12% of the explained variance with loadings ranging from 0.69 to 0.42. Both factors demonstrated adequate reliability. Factor 1 had a Cronbach's alpha of 0.91, while factor 2 was 0.72. As expected, AHMA conference attendees scored higher (F = 120.00, p < 0.001) than the internists on the IMAQ, supporting the construct validity. Although 63% of the AHMA subjects, and only 32% of the internists were female, analysis revealed that gender did not explain the score differences (F = 2.6, p > 0.05).Analysis of the IMAQ provided evidence of its reliability and validity in measuring attitudes toward CAM/IM, specifically openness to new ideas and paradigms, and the value of relationship to self and patient. Initial findings support use of the IMAQ in measuring attitudes of students and practitioners towards CAM/IM interventions as a first step in understanding willingness to use these approaches to healing. It is our desire that this preliminary instrument will continue to be refined as the field of CAM/IM matures.
