There is no consensus on how to determine appropriate financial compensation for research recruitment. Selecting incentive amounts that are reasonable and respectful, without undue inducement, remains challenging. Previously, we demonstrated that incentive amount significantly impacts participants’ willingness to complete various hypothetical research activities. Here we further explore this relationship in a mock decentralized study.

Adult ResearchMatch volunteers were invited to join a prospective study where interested individuals were given an opportunity to view details for a study along with participation requirements, then offered a randomly generated compensation amount between $0 and $50 to enroll and participate. Individuals agreeing to participate were then asked to complete tasks using a remote mobile application (MyCap), for two weeks. Tasks included a weekly survey, a daily gratitude journal and daily phone tapping task.

Willingness to participate was 85% across all incentive levels but not significantly impacted by amount. Task completion appeared to increase as a function of compensation until a plateau at $25. While participants described the study as low burden and reported that compensation was moderately important to their decision to join, only 31% completed all study tasks.

While offering compensation in this study did not have a strong effect on enrollment rate, this work provides insight into participant motivation when joining and participating in studies employing mobile applications.

People with dementia are more prone to premature nursing home placement after hospitalization due to physical and mental deconditioning which makes care-at- home more difficult. This study aimed to evaluate the effect of a post hospital discharge transitional care program on reduction of nursing home placement in people with dementia.

A matched case-control study was conducted between 2018 and 2021. A transitional care program using case management approach was developed. Participants enrolled the program by self-enrolment or referral from hospitals or NGOs. Community-dwelling people with dementia discharged from hospitals received a four- week residential care at a dementia care centre with intensive nursing care, physiotherapy and group activities promoting social engagement, followed by eight- week day care rehabilitation activities to improve their mobility and cognitive functioning. They were matched on a 1:5 ratio by age and sex to people with dementia discharged from a convalescent hospital who did not participate in this program for comparison. The study outcome was nursing home admission, measured three months (i.e. post-intervention), six months, and nine months after hospital discharge. Multinomial logistic regression was conducted to investigate factors associated with nursing home placement at each measurement time-point.

361 hospital admission episodes (n=67 interevntion, n=294 control) were examined. The regression results showed that participants in the intervention group were significantly less likely to be admitted to nursing home three months (OR = 0.023, 95% CI: 0.003-0.201, p = .001) and six months (OR = 0.094, 95% CI: 0.025-0.353, p = .001) than the controls after hospital discharge, but the intervention effect did not sustain nine months after hospital discharge. Longer hospital length of stay, and hospital admission due to dementia, mental disturbances such as delirium, or mental disorders IPA_Abstract_PDP_20230119_clean 2 such as schizophrenia significantly predicted nursing home admission three months and six months after hospital discharge.

The transitional care program could help reduce nursing home placement in people with dementia after hospital discharge. To sustain the intervention effect, more continual support after the intervention as well as family caregiver training would be required.

Bipolar disorder (BD) is a severe psychotic disease repeats depression, hypomania or mania. Using mobile applications to record emotions can help BD patients to self-manage and reduce emotional symptoms. Gamification applied in health-manage applications can improve the using frequency and satisfaction. Nurturing and horticultural therapy could increase the using frequency and alleviate the depression and anxiety.

This study chose plants-nurturing to add to a self-management application, and explored the users’ experiences.

A one-group pretest-posttest design with qualitative interview was used. Analysis included the frequency of usage, emotional changes, and users’ feedback of the plants-nurturing in the first three months and after three months.。

A total of 26 participants were included. In the frequency of usage, the times and ratio of days were increased but no significant difference. The emotional symptoms were no significant difference. Positive experiences were novelty and interesting, while negative experiences were the slow rate of growth.Table 1.Demographics (N=26)

There was a preliminary increase when adding plants-nurturing to the self-manage application, whereas the effect should be examined by further research. The more delicate elements of gamification could be included in self-manage application, considered the users’ other sensory perception in the future. Meanwhile, to improve the frequency of usage and self-management in BD patients, the subjective experiences should be explored in-depth.

Most of the research explored the attrition rate and predictive factors for the smartphone application of emotion monitoring in bipolar disorder patients. However, there is less focus on the efficacy of maintaining the retention rate if the incentive system is employed.

The aim of our research is to evaluate the efficacy of two different kinds of incentive systems on improving frequency of using the Smartphone Mood Relapse Warning application (MRW-APP) (Su et al., 2021) in bipolar patients.

A one-group pretest-posttest pilot study was conducted. Participants with bipolar disorder (n = 63) recorded their moods and symptoms through MRW-APP for 29 weeks with the attrition rate of 44%. Two different kinds of incentive systems, reward and lottery, were implemented. To know whether incentive implementation could play a role in motivating the participants to better adhere to the app, we used Friedman’s test and paired sample t-test to analyze the participants’ app-using frequency in the corresponding weeks.

There was no significant difference in the participants’ app-using frequency (p>.05) before and after we implemented the first incentive system, reward (n=63). For the second incentive system, lottery (n=41), a significant difference in app-using frequency was still not observed (p>.05) after the intervention. But, for those who both had experienced two kinds of incentive systems (n=35), there were significant changes in their app-using frequency (p<.05).Table 1.Demographics (n=63)

This research found the two incentive systems, award and lottery, may help increase the using frequency of the smartphone monitoring app for participants with bipolar disorder. The results from our study can be a reference for mood monitoring apps development in the future, and it also suggested that incentive system has its potential on encouraging patients’ adherence to e-healthcare.

Many clinical trials leverage real-world data. Typically, these data are manually abstracted from electronic health records (EHRs) and entered into electronic case report forms (CRFs), a time and labor-intensive process that is also error-prone and may miss information. Automated transfer of data from EHRs to eCRFs has the potential to reduce data abstraction and entry burden as well as improve data quality and safety.

We conducted a test of automated EHR-to-CRF data transfer for 40 participants in a clinical trial of hospitalized COVID-19 patients. We determined which coordinator-entered data could be automated from the EHR (coverage), and the frequency with which the values from the automated EHR feed and values entered by study personnel for the actual study matched exactly (concordance).

The automated EHR feed populated 10,081/11,952 (84%) coordinator-completed values. For fields where both the automation and study personnel provided data, the values matched exactly 89% of the time. Highest concordance was for daily lab results (94%), which also required the most personnel resources (30 minutes per participant). In a detailed analysis of 196 instances where personnel and automation entered values differed, both a study coordinator and a data analyst agreed that 152 (78%) instances were a result of data entry error.

An automated EHR feed has the potential to significantly decrease study personnel effort while improving the accuracy of CRF data.

Cognitive impairments are well-established features of psychotic disorders and are present when individuals are at ultra-high risk for psychosis. However, few interventions target cognitive functioning in this population.

To investigate whether omega-3 polyunsaturated fatty acid (n−3 PUFA) supplementation improves cognitive functioning among individuals at ultra-high risk for psychosis.

Data (N = 225) from an international, multi-site, randomised controlled trial (NEURAPRO) were analysed. Participants were given omega-3 supplementation (eicosapentaenoic acid and docosahexaenoic acid) or placebo over 6 months. Cognitive functioning was assessed with the Brief Assessment of Cognition in Schizophrenia (BACS). Mixed two-way analyses of variance were computed to compare the change in cognitive performance between omega-3 supplementation and placebo over 6 months. An additional biomarker analysis explored whether change in erythrocyte n−3 PUFA levels predicted change in cognitive performance.

The placebo group showed a modest greater improvement over time than the omega-3 supplementation group for motor speed (ηp2 = 0.09) and BACS composite score (ηp2 = 0.21). After repeating the analyses without individuals who transitioned, motor speed was no longer significant (ηp2 = 0.02), but the composite score remained significant (ηp2 = 0.02). Change in erythrocyte n-3 PUFA levels did not predict change in cognitive performance over 6 months.

We found no evidence to support the use of omega-3 supplementation to improve cognitive functioning in ultra-high risk individuals. The biomarker analysis suggests that this finding is unlikely to be attributed to poor adherence or consumption of non-trial n−3 PUFAs.

Alcohol consumption is a risk factor for various comorbidities, such as cirrhosis, chronic sclerosing stomatitis, and neuropsychiatric disorders.

Our study examined the associations between psychological factors and alcohol addiction of the individuals with alcohol use disorder (AUD) in Southern Taiwan.

Demographic information as well as suicidal history and sources of stress were collected from 177 participants. The extent of alcoholism was assessed by AUDIT questionnaire. Demographic and linear regression analyses were performed with the Statistical Software Stata version 12.0 (StataCorp LP, College Station, TX, USA).

Demographic data, suicidal history and the causes of stress of patients divided by AUDIT scores are shown in Table 1. Among 177 participants, 17 (9.6%) had suicidal thoughts, 4 (2.3%) had suicide plan, 22 (12.5%) self-injured, and four-fifth of patients lived under pressure. Patients who self-harmed were with significant lower AUDIT scores of -7.24 (95% CI: -11.49 – -3.00) (Table. 2). The AUDIT scores of patients with physical stress, interpersonal difficulties and loneliness increased significantly by 6.71 (95% CI: 3.19 – 10.30), 6.14 (95% CI: 2.15 – 10.13) and 5.02 (95% CI: 0.93 – 9.11), respectively (Table. 3).

Our findings indicated negative correlation with alcohol use and auto-inflicted injury. However, previous study showed systematic assessment of the association between suicide and AUD, and considered alcohol an important risk factor for suicide, which is related to mental health and affected by different genders and drinking patterns. Our results may provide reference for estimation of the alcohol-related psychological effects in Taiwan.

Glutamatergic dysfunction has been implicated in sensory integration deficits in schizophrenia, yet how glutamatergic function contributes to behavioural impairments and neural activities of sensory integration remains unknown.

Fifty schizophrenia patients and 43 healthy controls completed behavioural assessments for sensory integration and underwent magnetic resonance spectroscopy (MRS) for measuring the anterior cingulate cortex (ACC) glutamate levels. The correlation between glutamate levels and behavioural sensory integration deficits was examined in each group. A subsample of 20 pairs of patients and controls further completed an audiovisual sensory integration functional magnetic resonance imaging (fMRI) task. Blood Oxygenation Level Dependent (BOLD) activation and task-dependent functional connectivity (FC) were assessed based on fMRI data. Full factorial analyses were performed to examine the Group-by-Glutamate Level interaction effects on fMRI measurements (group differences in correlation between glutamate levels and fMRI measurements) and the correlation between glutamate levels and fMRI measurements within each group.

We found that schizophrenia patients exhibited impaired sensory integration which was positively correlated with ACC glutamate levels. Multimodal analyses showed significantly Group-by-Glutamate Level interaction effects on BOLD activation as well as task-dependent FC in a ‘cortico-subcortical-cortical’ network (including medial frontal gyrus, precuneus, ACC, middle cingulate gyrus, thalamus and caudate) with positive correlations in patients and negative in controls.

Our findings indicate that ACC glutamate influences neural activities in a large-scale network during sensory integration, but the effects have opposite directionality between schizophrenia patients and healthy people. This implicates the crucial role of glutamatergic system in sensory integration processing in schizophrenia.
