Patient-Centered Measure Development and Spanish Validation Exemplar

Pilot Testing Transcreated Spanish-Language Study Materials for Symptom Research With Infants and Parents in the Neonatal Intensive Care Unit

BACKGROUND

Rising admission rates of Hispanic/Latinx families to the neonatal intensive care unit (NICU) have increased the number of non-English-speaking individuals who may wish to participate in research studies. However, a lack of appropriately translated research study materials may limit the opportunity for these families to be involved in research that could impact the care that infants and families receive in the NICU.

PURPOSE

The primary purpose was to pilot test study materials that were transcreated from English to Spanish with the assistance of a bilingual community advisory board with Spanish-speaking parents of NICU infants.

METHODS

A total of 19 Spanish-speaking parents (15 mothers and 4 fathers) who were representative of the population of interest completed paper-and-pencil surveys, along with a cognitive interview. Preliminary data related to decision-making and goals of care, infant symptoms, and their experiences in the NICU were also collected.

RESULTS

The internal reliability of the transcreated study instruments ranged from good to excellent (α= 0.82-0.99). Participants reported that study materials were not offensive and did not make them feel uncomfortable; however, they found some words/phrases to be confusing. Parents had the opportunity to provide suggested wording changes.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Language barriers and a lack of cultural responsiveness can affect the care that infants and their families receive. More accurate and culturally appropriate transcreation of study materials can remove barriers to research participation and facilitate better communication with non-English-speaking families, which may lead to the development of better-informed evidence-based interventions and clinical practices in the NICU.

Development of the multidimensional health perceptions questionnaire in English and Spanish

Purpose

To develop the novel multidimensional health perceptions questionnaire (MHPQ), a self-reported assessment of health perceptions inclusive of (1) individuals beliefs about the causes and consequences of health conditions, benefits and barriers to maintaining and improving health, ability to accomplish health-related goals and control health circumstances, and the role of God and/or spirituality in health and healthcare, (2) anticipated discrimination in the healthcare systems, and (3) trust in healthcare providers and medicine, illustrated in our newly proposed Multidimensional Health Perceptions Conceptual Model.

Methods

We developed an initial MHPQ_β item set, corresponding to domains of our conceptual model, using a patient-centered outcomes development approach. This include literature review, expert and end-user feedback, translation and language validation (specifically to Latin American Spanish), and cognitive interviewing.

Results

The initial 104 items of MHPQ_β had excellent content validity, with a Content Validity Index of 98.1%. After expert (n = 13) feedback, translation and language validation, and cognitive interviewing among community-dwelling English-speakers (n = 5) and Spanish-speakers (n = 4), the final MHPQ_β comprised 93 items rated on a five-point agreement scale (1 = Strongly disagree to 5 = Strongly agree), with a reading grade level of 6th grade in English and 8th grade in Spanish.

Conclusion

The MHPQ_β is a promising tool to assess individuals’ health perceptions. It has excellent content validity and good reading accessibility. Future work will establish the factor structure and final item set of the MHPQ.

Rasch analysis of the Behavioral Assessment Screening Tool (BAST) in chronic traumatic brain injury

The Behavioral Assessment Screening Tool (BAST) measures neurobehavioral symptoms in adults with traumatic brain injury (TBI). Exploratory Factor Analyses established five subscales: Negative Affect, Fatigue, Executive Function, Impulsivity, and Substance Abuse. In the current study, we assessed all the subscales except Substance Abuse using Rasch analysis following the Rasch Reporting Guidelines in Rehabilitation Research (RULER) framework. RULER identifies unidimensionality and fit statistics, item hierarchies, targeting, and symptom severity strata as areas of interest for Rasch analysis. The BAST displayed good unidimensionality with only one item from the Impulsivity scale exhibiting potential item misfit (MnSQ 1.40). However, removing this item resulted in a lower average domain measure (1.42 to -1.49) and higher standard error (0.34 to 0.43) so the item was retained. Items for each of the four subscales also ranged in difficulty (i.e. endorsement of symptom frequency) with more severe symptoms being endorsed in the Fatigue subscale and more mild symptoms being endorsed in the Impulsivity subscale. Though Negative Affect and Executive Function displayed appropriate targeting, the Fatigue and Impulsivity Subscales had larger average domain values (1.35 and -1.42) meaning that more items may need to be added to these subscales to capture differences across a wider range of symptom severity. The BAST displayed excellent reliability via item and person separation indices and distinct strata for each of the four subscales. Future work should use Rasch analysis in a larger, more representative sample, include more items for the Fatigue and Impulsivity subscale, and include the Substance Abuse subscale.

Psychometric analysis of the behavioral assessment screening tool (BAST) in adults with stroke

PURPOSE

The purpose of this study was to examine the initial psychometric properties of the Behavioral Assessment Screening Tool (BAST), a self-reported measure of neurobehavioral symptoms, in adults with stroke.

METHODS

We assessed subscale and item-level reliabilities of the five BAST subscales in 75 community-dwelling adults with stroke. We further assessed the known-groups validity of the BAST to differentiate individuals with and without self-reported lifetime stroke history (n = 47 with stroke and n = 1843 neurologically healthy controls).

RESULTS

Cronbach's alpha coefficients of all subscales were >0.7, demonstrating acceptable to good internal consistency reliabilities, and corrected item-total correlations were all >.30 demonstrating good item-level reliabilities. ROC curves demonstrated strong known-groups validity of the negative affect, executive function, and fatigue subscales for classifying stroke versus healthy controls (AUC = .669-.758, p < .001).

CONCLUSION

The BAST demonstrates good initial psychometric properties as a screening tool to identify neurobehavioral symptoms in community-dwelling adults with stroke. Future work will add stroke-specific items, further assess the validity of the BAST, and employ item response theory or Rasch analyses to identify highly discriminative items for potential smart device-based ecological momentary assessments.

Associations between frequent pain or headaches and neurobehavioral symptoms by gender and TBI severity

Objective: To investigate differences in frequent pain or headaches and associated neurobehavioral symptoms among men, women, and transgender individuals with and without a history of traumatic brain injury (TBI).Setting: CommunityParticipants: English and Spanish-speaking adults (n = 2,862) with and without self-reported TBIDesign: Cross-sectional studyMain Measures: Behavioral Assessment Screening Tool (BAST) subscales for Negative Affect, Substance Abuse, Executive Function, Fatigue, Impulsivity, and one item for experiencing "frequent pain or headache."Results: Women reported more pain than men. Women with a mild TBI (mTBI) more often reported frequent headaches/pain than woman in general or those with mTBI alone. Women reporting frequent headache/pain reported more negative affect and fatigue than men with comparable TBI history. Individuals identifying as transgender/other without TBI had higher negative affect and fatigue than both men and women without TBI. Individuals with mTBI and frequent headache/pain reported more executive function problems than those with mTBI without headache/pain. Pain and moderate/severe TBI were associated with more executive function problems in men and women, but more so for women.Conclusion: Results suggest frequent headache/pain may differ between genders, particularly after mTBI. Pain, fatigue, executive function, and negative affect may be especially important in women's recovery from TBI.

Neurobehavioral Symptoms in Community-Dwelling Adults With and Without Chronic Traumatic Brain Injury: Differences by Age, Gender, Education, and Health Condition

Neurobehavioral symptoms after Traumatic Brain Injury (TBI) are prevalent, persist for many years, and negatively affect long-term health, function, and quality of life. Symptoms may differ based on age, gender, education, race, ethnicity, and injury severity. To better understand neurobehavioral functioning after TBI, we need a comprehensive picture of emotional, cognitive, and behavioral symptoms in the context of personal factors that may affect these symptoms. We also need to understand the extent to which these symptoms are specific to TBI, shared across other neurological conditions, or attributable to factors outside of the injury itself. We collected neurobehavioral symptoms via the self-reported Behavioral Assessment Screening Tool (BAST) in a National Cohort of English (n = 2,511) and Spanish speaking (n = 350) community-dwelling adults with and without chronic TBI and other neurological and mental health conditions. The primary focus of the present study was to comprehensively describe neurobehavioral symptoms in adults with and without TBI, broken down by gender and health conditions and then further by age group or educational attainment. As expected, participants with TBI reported more symptoms than Healthy Controls. Regardless of condition, women reported more fatigue, while men reported more substance abuse and impulsivity. Hispanic participants reported more neurobehavioral symptoms than non-Hispanic participants did across health conditions, though primarily Spanish-speakers reported fewer symptoms than English-speakers, suggesting that level of acculturation may contribute to symptom reporting. These data provide a comprehensive characterization of neurobehavioral symptoms in adults with TBI and adults without TBI (healthy controls, adults with other neurological conditions, and adults with mental health conditions).
