Exploring Mechanisms of Measurement Discrepancy: Perceived Acceptability and Efficiency of Two Sexual Victimization Questionnaires

Background: Obtaining accurate prevalence rates of sexual violence is made difficult by discrepancies in self-reporting questionnaires. Thus, the current study sought to explore participants' perceptions of acceptability (i.e., perceived difficulty, readability, and preference) of questionnaires as an important psychometric indicator and a potential mechanism of discrepancy between different questionnaires assessing sexual victimization. Methods: Participants were 673 college students who completed the Sexual Experiences Survey-Short Form Victimization (SES-SFV) and the Post-Refusal Sexual Persistence Scales-Victimization (PRSPS-V). Participants then answered questions about each measure's perceived difficulty and their preference between the two. Flesch-Kincaid Reading Grade Level and efficiency (i.e., number of items: number of cases identified) were also analyzed. Results: Participants found the PRSPS-V easier to understand and preferred it 2.5 to1 over the SES-SFV. Preference was related to reporting; participants who preferred the PRSPS-V reported more instances of sexual victimization on the PRSPS-V. The PRSPS-V was objectively easier to comprehend according to Flesch-Kincaid levels and was two times more efficient than the SES-SFV in the number of cases detected per item administered. Conclusions: Our results indicate that acceptability impacts reported prevalence rates and is one mechanism for documented discrepancies between sexual violence questionnaires. Thus, it may behoove researchers to consider acceptability as a metric of interest when choosing sexual victimization questionnaires.

Difficult Topics in the Chemistry Curriculum – Bulgarian Students‘ View

Chemistry is often considered a difficult subject, and the way students perceive learning affects their achievements. The research aims to identify: the topics in the secondary Chemistry curriculum perceived as difficult and as interesting by the Bulgarian students, the reasons for students’ difficulties and ways to overcome it. An inquiry was conducted with 321 students aged 16 – 17 years. According to them, the most difficult topics are Organic Chemistry and Chemical calculations (abstract and requiring specific skills). The most interesting topics are Organic Chemistry and Theory of Electrolytic Dissociation. Acids and bases. There is no significant correlation between levels of perceived difficulty and interest. Students relate difficulties to: information overload, emphasis on memorization, and lack of connections to everyday life. More lab activities and the practical application of the knowledge are recommended. Our research results can help improve Chemistry curricula and teaching practice.

VestAid: A Tablet-Based Technology for Objective Exercise Monitoring in Vestibular Rehabilitation

(1) Background: Current vestibular rehabilitation therapy is an exercise-based approach aimed at promoting gaze stability, habituating symptoms, and improving balance and walking in patients with mild traumatic brain injury (mTBI). A major component of these exercises is the adaptation of the vestibulo-ocular reflex (VOR) and habituation training. Due to acute injury, the gain of the VOR is usually reduced, resulting in eye movement velocity that is less than head movement velocity. There is a higher chance for the success of the therapy program if the patient (a) understands the exercise procedure, (b) performs the exercises according to the prescribed regimen, (c) reports pre- and post-exercise symptoms and perceived difficulty, and (d) gets feedback on performance. (2) Methods: The development and laboratory evaluation of VestAid, an innovative, low-cost, tablet-based system that helps patients perform vestibulo-ocular reflex (VORx1) exercises correctly at home without therapist guidance, is presented. VestAid uses the tablet camera to automatically assess patient performance and compliance with exercise parameters. The system provides physical therapists (PTs) with near real-time, objective (head speed and gaze fixation compliance), and subjective (perceived difficulty and pre- and post- exercise symptoms) metrics through a web-based provider portal. The accuracy of the head-angle and eye-gaze compliance metrics was evaluated. The accuracy of estimated head angles calculated via VestAid’s low-complexity algorithms was compared to the state-of-the-art deep-learning method on a public dataset. The accuracy of VestAid’s metric evaluation during the VORx1 exercises was assessed in comparison to the output of an inertial measurement unit (IMU)-based system. (3) Results: There are low mean interpeak time errors (consistently below 0.1 s) across all speeds of the VORx1 exercise, as well as consistently matching numbers of identified peaks. The spatial comparison (after adjusting for the lag measured with the cross-correlation) between the VestAid and IMU-based systems also shows good matching, as shown by the low mean absolute head angle error, in which for all speeds, the mean is less than 10 degrees. (4) Conclusions: The accuracy of the system is sufficient to provide therapists with a good assessment of patient performance. While the VestAid system’s head pose evaluation model may not be perfectly accurate as a result of the occluded facial features when the head moves further towards an extreme in pitch and yaw, the head speed measurements and associated compliance measures are sufficiently accurate for monitoring patients’ VORx1 exercise compliance and general performance.

Who accepts nudges? nudge acceptability from a self-regulation perspective

Background Public acceptability of nudging is receiving increasingly more attention, but studies remain limited to evaluations of aspects of the nudge itself or (inferred intentions) of the nudger. Yet, it is important to investigate which individuals are likely to accept nudges, as those who are supposed to benefit from the implementation should not oppose it. The main objective of this study was to integrate research on self-regulation and nudging, and to examine acceptability of nudges as a function of self-regulation capacity and motivation. Method Participants (N = 301) filled in questionnaires about several components of self-regulation capacity (self-control, proactive coping competence, self-efficacy, perceived control and perceived difficulty) and motivation (autonomous motivation and controlled motivation). To evaluate nudge acceptability, we used three vignettes describing three types of nudges (default, portion size, and rearrangement) that stimulated either a pro-self behavior (healthy eating) or pro-social behavior (sustainable eating) and asked participants to rate the nudges on (aspects of) acceptability. Results Results revealed that there were substantial differences in acceptability between the three types of nudges, such that the default nudge was seen as less acceptable and the rearrangement nudge as most acceptable. The behavior that was stimulated did not affect acceptability, even though the nudges that targeted healthy eating were seen as more pro-self than the nudges targeting sustainable eating. From all self-regulation components, autonomous motivation was the only measure that was consistently associated with nudge acceptability across the three nudges. For self-regulatory capacity, only some elements were occasionally related to acceptability for some nudges. Conclusion The current study thus shows that people are more inclined to accept nudges that target behaviors that they are autonomously motivated for, while people do not meaningfully base their judgments of acceptability on self-regulatory capacity.

Predicting Factors among Healthy Lifestyle Beliefs, Behaviors and Mental Health Indicators in Taiwanese Adolescents

Aims: The prevalence of overweight adolescents in Taiwan has dramatically increased in recent years. A survey shows that 66.6% of adolescents do not get the recommended amount of vegetables and fruit (i.e., two portions of fruit and three portions of vegetables per day each week). The purpose of this study was to explore relationships between individual understanding of activity and nutrition, healthy lifestyle beliefs, perceived difficulty of efficacy in reaching health goals, mental health variables, and healthy lifestyle behavior on BMI in Taiwanese adolescents. Study Design: This is a theoretically-based and cross-sectional research study. Place and Duration of Study: Data were conducted from two middle schools in Taiwan between Sep 2011 to November 2011. Methodology: We used a convenience sampling to recruit 453 adolescents with a mean age of 13.42 years. The instruments used were demographics, Beck Youth Inventory II (Depression, Anxiety, Self-concept), Healthy Lifestyle Belief Scale, Healthy Lifestyle Behavior Scale, Perceived Difficulty Scale, Nutrition and Activity Knowledge Scales. We conducted path analysis to test our theoretical model by using Mplus 5.21. Results: Fit indices included χ2 (23, 453) =33.75, P= .05, CFI=.98, and RMSEA=.03, indicating that the model fit the model well. Healthy lifestyle beliefs had a significant positive effect on healthy lifestyle behaviors (β= .41, P= .01). Moreover, there was a significant negative relationship between perceived difficulty and healthy lifestyle behaviors (β= -.54, P= .01). Conclusion: Our findings suggest that promoting positive beliefs about healthy lifestyle among adolescents may facilitate healthy lifestyle changes and help them perceive less difficulty in maintaining a healthy lifestyle. School nurses and health professionals in Taiwan need to coordinate essential resources and implement theoretical-based educational program that address issues on increasing adolescents’ healthy lifestyle beliefs.

Perceived difficulty of getting help to reduce or abstain from substances among sexual and gender minority men who have sex with men (SGMSM) and use methamphetamine during the early period of the COVID-19 pandemic

Background This study examined the perceived difficulty of getting help with substance use among sexual and gender minorities who have sex with men (SGMSM) who use methamphetamine during the early COVID-19 period. Methods SGMSM, aged 18+, who reported sex with a man and methamphetamine use in the past 6 months were recruited to complete an online survey using online advertisements. Ordinal regression models examined predictors of greater perceived difficulty of getting help. Explanatory variables included participant characteristics (i.e., age, HIV status, ethnicity, sexuality, gender, region, income) and variables assessing patterns of methamphetamine use (i.e., frequency, % time methamphetamine is used alone and during sex; perceived need for help) and patterns of healthcare access (i.e., regular provider, past substance use service utilization). Results Of 376 participants, most were gay-identified (76.6%), white (72.3%), cisgender (93.6%), and had annual incomes of less than $60,000 CAD (68.9%). Greater perceived difficulty of getting help was associated with having lower income, sometimes using methamphetamine prior to or during sex, and greater perceived need for help. Conclusion Based on these results, we urge greater investments in one-stop, low-barrier, culturally-appropriate care for SGMSM who use methamphetamine. This is especially important given that participants who perceive themselves as needing help to reduce or abstain from substance use perceive the greatest difficulty of getting such help.

JARET: A Human Assistive A.I. Agent for Goal Review and Time Management

Many students do not set goals or plan their time weekly (due to lack of ability, perceived difficulty, and other reasons) resulting in procrastination, stress, and lower academic performance. This paper presents the design methodology and considerations for a human assistive AI agent that helps students review and plan for study goals, reducing a large abstract problem into a set of simpler review tasks. J.A.R.E.T. (Just A Recommender Engine for Time) uses key principles from Self-Regulated Learning and Cognitive Load Theory in an interactive system that guides students through focused goal review and planning tasks, then uses a constraint satisfaction AI agent to assemble a proposed calendar schedule designed to help achieve the student’s goals. The AI agent uses hard and soft constraints with a value function designed and searches for a best fit that follows constraints while trying to also fit student preferences. Results show that the design is able to reliably build recommended solutions when constraints and preferences are reasonable and not overly restrictive.

Bridging the technological divide: Stigmas and challenges with technology in clinical studies of older adults.

The COVID-19 pandemic has increased adoption of remote assessments in clinical research. However, longstanding stereotypes persist regarding older adults’ technology familiarity and their willingness to participate in technology-enabled remote studies. We examined the validity of these stereotypes using a novel technology familiarity assessment (n = 342) and with a critical evaluation of participation factors from an intensive smartphone study of cognition in older adults (n = 445). The technology assessment revealed that older age was strongly associated with less technology familiarity, less frequent engagement with technology, and higher difficulty ratings. Despite this, the majority (86.5%) of older adults elected to participate in the smartphone study and showed exceptional adherence (85.7%). Furthermore, among those enrolled, neither technology familiarity, knowledge, perceived difficulty, nor gender, race, or education were associated with adherence. These results suggest that while older adults remain significantly less familiar with technology than younger generations, with thoughtful study planning that emphasizes participant support and user-centered design, they are willing and capable participants in technology-enabled studies. And once enrolled, they are remarkably adherent.

Implementation of a Low-Cost 3D-Printed Feline Larynx Model for Veterinary Students

Endotracheal intubation (EI) in domestic cats is an important skill that veterinary students learn in order to perform anesthesia safely in this species. Implementing a 3D-printed larynx model (LaryngoCUBE) during the instruction process may improve student’s learning of EI in felines. Twenty-two third-year students performed EI in cats with standard training (ST), and 16 students trained with the model (MT) the day before the laboratory. It was evaluated whether training with the model decreases the time and number of EI attempts, students’ perceived difficulty performing EI using a visual analog score (VAS; 0 cm = very easy, 10 cm = extremely difficult; median [minimum–maximum]), and the incidence of failure to perform EI. The EI time on ST (58 [18–160] seconds) was longer, but not statistically different from MT (29 [13–120] seconds; p = .101). The number of EI attempts on ST (2 [1–3]) was higher than MT (1 [1–3]; p = .005). The VAS on the ST and MT were 4.5 (0.0–10.0) cm and 3.0 (0.2–10.0) cm, respectively ( p = .029). The failure rate was 27% on the ST and 25% on the MT ( p = 1.000). Students who practiced with a larynx model took fewer attempts to perform EI, tended to be faster, and found that EI was easier. However, the EI success rate in MT was not improved.
