New vignettes for the experimental manipulation of injury cause in prospective mild traumatic brain injury research

Perceptions of Caring Recruitment Among Older Adults: African Americans and Non-Latinx Whites

BACKGROUND

African Americans (AAs) are underrepresented in health-related research studies. Few studies have investigated how behaviors of study recruiters affect recruitment of older AAs versus non-Latinx Whites (NLWs).

OBJECTIVES

The aim of this study was to explore whether caring behaviors influence AA and NLW older adults' decision to participate in hypothetical, high-commitment, health-related research studies and differences in participants' enrollment decisions by race.

METHODS

Using a descriptive, cross-sectional study design, guided by Kristen Swanson's middle-range theory of caring, a research-savvy sample of 60 AA and 60 NLW adults (age > 65 years) were randomly assigned one of two written vignettes. The concept of caring behaviors was manipulated and illustrated in a hypothetical recruitment scenario. A participant feedback survey was used to assess (a) participants' perceptions of caring and uncaring behaviors exhibited by the fictitious research recruiter, (b) differences in their willingness to participate based on vignette type, and (c) participants' judgment of the research recruiter as being caring or uncaring. A chi-square test assessed the association among categorical variables (caring behavior and participants' race).

RESULTS

Participants who received the vignette with the high caring recruiter were more than twice as likely to agree to participate in the study than those who received the vignette with the low caring recruiter. AA and NLW participants did not differ in their likelihood to agree to participate. Participants who received the caring vignette and judged the recruiter as caring were 5 times as likely to agree to participate in the high-commitment study than those who received the uncaring vignette ( p < .001). Associations did not vary by race.

DISCUSSION

This experimental study of equally recruited older adults from an existing longitudinal study revealed that caring behaviors in recruitment strategies are associated with an increased likelihood of participation in high-commitment research with older adults. The research-savvy AA participants were just as likely to participate in the hypothetical high-commitment research as their NLW peers when the fictional research recruiter was perceived as having caring behaviors. When targeting specific populations, it is essential to employ nuanced recruitment approaches where the study recruiters are attuned to caring behaviors.

Using Vignette-Based Methodology to Examine Study Recruitment in Older African American Adults: A Methods Paper

This study's objective was to assess which caring recruitment behaviors correlate with the successful recruitment of older African-American adults-a two-step cross-sectional design employing a vignette-based survey methodology. Kristen Swanson's middle-range theory of caring was used to guide the examination of African-American adults' (65 years of age and older) perceptions of research-study-recruiter recruitment behaviors. This study's main findings are twofold: Step 1: Seven of ten invited experts identified major revisions of the two core vignettes, written at an eighth-grade reading level and high school comprehension. Step 2: A 51% response rate yielded findings that this methodology successfully captured older African-American adults' perception of research study recruiters' behavioral characteristics during the recruitment process. Older African-Americans who received the hypothetical caring vignette were twice as likely to indicate their willingness to enroll in a research study with a high commitment (i.e., brain donation) compared to their counterparts who received the hypothetical uncaring recruitment scenario. Vignette-based survey methodology holds promise as a tool for informing the recruitment of older African-American adults and other minorities into federally funded health-related research studies.

Prior head injury but not sex or sports-participation affects expectations for post-injury rest and activity in simulated mild traumatic brain injury

Rest acutely followed by a gradual return to activity is commonly recommended for mild traumatic brain injury (TBI). However, the general public's rest and activity expectations for this injury are unknown, as are the individual factors that might affect them. 165 individuals completed an online survey. A series of between-groups comparisons of expectations for the week following a mild TBI was performed. The comparisons were between individuals with or without a prior mild TBI; sports-playing versus non-sports-playing individuals, and; females versus males. Expectations were elicited for 39 everyday behaviours referred to in mild TBI patient advice. Compared to a rating indicating 'no change' in the amount of pre-injury activity, "rest" was expected for 37 items (p's < .05). Expectations were not different based on participants' sex or sports-participation. However, for seven predominantly cognitive items such as studying, a prior injury increased rest expectations (p < .05; small-to-medium effects). The findings indicate that whilst the proposed activity restrictions are appropriate for some circumstances such as acutely postinjury, they have the potential to be overly strong. To address this potential, especially with first-ever injury, clinicians and sports officials should check their patient's postinjury rest and activity plans when providing active rest advice.

The Mild Traumatic Brain Injury Rest and Activity Questionnaire (MTBI-RAQ): A Pilot Study

Objective: To develop a tool for assessing intentions to continue or change activities for recovery following mild traumatic brain injury (mTBI) and determine if they are dependent on injury context or activity type. Method: Adult volunteers with no (or no recent) history of mTBI were randomly allocated to one of two vignette conditions, each with a different injury context. The vignette described an mTBI due to a motor vehicle accident (MVA, n = 76) or sport (SPORT, n = 89). Volunteers reported their rest or activity plans for 39 behaviours comprising three behaviour types (cognitive, physical, and restful). Results: Compared to a cut-score representing no change, on average there was a significant (p <= .001) planned decrease in physical and cognitive behaviours (MVAphysicalt(53) = 7.373; SPORTphysicalt(41) = 9.281; MVAcognitivet(41) = 9.367; SPORTcognitivet(51) = −3.521) and a significant planned increase in restful behaviours, such as sleep (MVArestfult(72) = 10.006; SPORTrestfult(86) = 9.566). An overall within-group effect for behaviour-type was not identified and there was no effect of condition (MVA vs. SPORT). Conclusion: The acute rest and activity plans for a simulated mTBI are behaviour specific and not dependent on context. An expectation for blanket-rest was not was observed but rest was planned for specific behaviours. This tool could be used to guide discussions with mTBI patients about their recovery so that their plans align with advice, and it could aid further research into the relation between intended and actual rest and activity and the effect on eventual outcomes.

Assault-related mild traumatic brain injury, expectations of injury outcome, and the effect of different perpetrators: A vignette study

Few studies have examined the effect of varying the assault perpetrator on expectations of outcome from mild TBI. Using a cross sectional between groups design, individuals with no history of mild TBI were randomly allocated to one of two vignette conditions. The vignette depicted a mild TBI with fixed injury parameters and a different assault perpetrator (partner, n = 27; or stranger, n = 27). The participants were instructed to imagine that they had been injured as per the depiction, and then to anticipate the injury consequences 6-months later. An online questionnaire was used including: the Neurobehavioral Symptom Inventory, the Posttraumatic Stress Disorder Checklist-Civilian Version, the Impact of Events Scale-Revised, and the Perceived Ability to Cope with Trauma. The depicted injury was rated for the extent to which it was perceived as life-threatening, the subsequent diagnosis, and the global recovery prospects. The anticipated consequences of the injury (symptoms and trauma variables) did not differ across the conditions, all p's > 0.05. The expected outcomes for an assault-related mild TBI were not affected by perpetrator type. However, the study had several limitations and further consideration of this factor may still be warranted.
