Using rapid cycle tests of change to develop the Carers Assistive Technology Experience Questionnaire: a cognitive interview study in the UK

Translation and validation of the Breastfeeding Motivation Scale in China

BACKGROUND

There are several versions of the Breastfeeding Motivation Scale (BMS), which have been shown to measure maternal breastfeeding motivation, but there is not a Chinese version yet. The study aimed to translate the BMS into Chinese and subsequently assess its psychometric properties among Chinese mothers during the postpartum period.

METHODS

The study was composed of two phases. The translation of BMS closely followed the principals of good practices. Phase 1 included a comprehensive translation, back-translation, cross-cultural adaptation, and pretest to develop the Chinese version of the BMS. From 1 December 2021 to 1 July 2022, the Chinese version of the BMS was administered to 206 postnatal mothers in our maternity wards to assess its psychometric properties. Phase 2 involved psychometric property testing, including testing of the internal consistency, test-retest reliability, content validity, construct validity, convergent validity and discriminant validity.

RESULTS

Minor modifications in four items were recommended after translations. The Cronbach's α coefficient of the Chinese version of the BMS was .887, and the intraclass correlation coefficient was .897 (P < 0.001). The model fit was acceptable (χ2/df = 2.40, P < 0.001, RMSEA = 0.08, CFI = 0.91, IFI = 0.92 and TLI = 0.90) according to the confirmatory factor analysis. The composite reliability values corresponding to each latent variable were 0.733 ~ 0.926, and the average variance extracted values were 0.476 ~ 0.653. The correlations among the five measured variables were all lower than .85 and the square roots of average variance extracted from the variable were greater than the interconstruct correlations among the five measured variables in the model.

CONCLUSIONS

The Chinese version of the BMS has good reliability and validity and provides a reliable assessment tool for measuring maternal breastfeeding motivation. It also provides support to develop culturally sensitive interventions for Chinese mothers' who are breastfeeding.

The Technology in Caring Questionnaire: Development and Psychometric Properties

OBJECTIVE

We developed the Technology in Caring Questionnaire (TCQ) to assess the use of technology-based strategies by dementia caregivers.

METHODS

One hundred caregivers completed a survey that included TCQ items along with measures of technology proficiency and patient and caregiver-centered outcomes.

RESULTS

The final 34-item TCQ scale had adequate to excellent internal consistency (raw Cronbach alpha = 0.75; standardized Cronbach alpha = 0.95; Guttman lambda-6 = 0.97). TCQ scores demonstrated modest convergent associations with scores from measures of smartphone ( r = 0.265, P < 0.01) and computer proficiency ( r = 0.230, P < 0.05) but a strong association with overall technology experience scores ( r = 0.578, P < 0.001). Elevated TCQ scores were associated with reduced informant-reported cognitive symptoms ( B = -0.003, P < 0.05), increased ability of caregivers to find support and information ( B = 0.03, P < 0.001), and increased direct care strain ( B = 0.03, P < 0.05), after controlling for dementia severity and demographics.

CONCLUSION

The TCQ has good psychometric properties for the assessment of technology-based care strategies among dementia caregivers. Findings imply that the use of technologies may aid in symptom management and finding support and information but may also increase caregiver strain.

A Qualitative Study on the Experiences of Therapists Delivering the Promoting Activity, Independence and Stability in Early Dementia (PrAISED) Intervention During the COVID-19 Pandemic

BACKGROUND

The Promoting Activity, Independence and Stability in Early Dementia (PrAISED) intervention is a programme of physical activity and exercise designed to maintain participation in activities of daily living, mobility, and quality of life for people living with dementia. During the COVID-19 pandemic first national lockdown in England, the PrAISED physiotherapists, occupational therapists, and rehabilitation support workers adapted to delivering the intervention remotely via telephone or video conferencing.

OBJECTIVE

The aim of this study was to explore therapists' experience of delivering the PrAISED intervention during the COVID-19 pandemic and derive implications for clinical practice.

METHODS

Qualitative semi-structured interviews were conducted with 16 therapists using purposive sampling. Thematic analysis was used to analyze the transcripts.

RESULTS

Therapists reported a change in the relationship between themselves, the person with dementia and the caregiver, with an increased reliance on the caregiver and a loss of autonomy for the person living with dementia. There was concern that this would increase the burden on the caregiver. The therapists reported using creativity to adapt to different modes of delivery. They felt their sessions were mostly focused on providing social and emotional support, and that assessing, progressing, and tailoring the intervention was difficult.

CONCLUSION

It is possible to deliver some elements of a physical intervention using remote delivery, but a dual modal approach including remote and face-to-face delivery would optimize treatment efficacy. Educational support would be required to enable people living with dementia and their caregivers to overcome barriers relating to digital literacy.

Translation Into Simplified Chinese and Cultural Validation of the Pediatric Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events Using Cognitive Interviewing

BACKGROUND

The original English Pediatric Patient-Reported Outcome version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) captures symptomatic adverse events (AEs) in cancer clinical trials from the perspective of pediatric patients. A Chinese version was needed to encourage the use of the Pediatric PRO-CTCAE among Chinese pediatric oncology patients.

OBJECTIVE

This study translated and linguistically validated a simplified Chinese version of the Pediatric PRO-CTCAE for oncological patients aged 7 to 18 years.

METHODS

Following the Functional Assessment of Chronic Illness Therapy translation methodology, 130 questions were translated into Chinese. Semistructured cognitive interviews investigated the comprehensibility and clarity of terms for symptoms, attributes, and response options. Two rounds of interviews were conducted with 48 native Chinese-speaking children aged 7 to 18 years who were undergoing chemotherapy or radiotherapy treatment.

RESULTS

Most items, response options, and recall periods were well understood by children across the age range in round 1. Nineteen items posed comprehension difficulties for 9 participants and were revised and retested without further difficulties.

CONCLUSIONS

The Pediatric PRO-CTCAE was successfully developed and linguistically validated among Chinese oncology patients. The results indicated that the Chinese Pediatric PRO-CTCAE was semantically and conceptually equivalent to the English version.

IMPLICATIONS FOR PRACTICE

The availability of the simplified Chinese Pediatric PRO-CTCAE will facilitate the generation of patient-reported outcome data about symptomatic AEs for children with cancer in China and thus improve our understanding of children's experience of treatment-related symptoms.

An Intelligent Learning System for Unbiased Prediction of Dementia Based on Autoencoder and Adaboost Ensemble Learning

Dementia is a neurological condition that primarily affects older adults and there is still no cure or therapy available to cure it. The symptoms of dementia can appear as early as 10 years before the beginning of actual diagnosed dementia. Hence, machine learning (ML) researchers have presented several methods for early detection of dementia based on symptoms. However, these techniques suffer from two major flaws. The first issue is the bias of ML models caused by imbalanced classes in the dataset. Past research did not address this issue well and did not take preventative precautions. Different ML models were developed to illustrate this bias. To alleviate the problem of bias, we deployed a synthetic minority oversampling technique (SMOTE) to balance the training process of the proposed ML model. The second issue is the poor classification accuracy of ML models, which leads to a limited clinical significance. To improve dementia prediction accuracy, we proposed an intelligent learning system that is a hybrid of an autoencoder and adaptive boost model. The autoencoder is used to extract relevant features from the feature space and the Adaboost model is deployed for the classification of dementia by using an extracted subset of features. The hyperparameters of the Adaboost model are fine-tuned using a grid search algorithm. Experimental findings reveal that the suggested learning system outperforms eleven similar systems which were proposed in the literature. Furthermore, it was also observed that the proposed learning system improves the strength of the conventional Adaboost model by 9.8% and reduces its time complexity. Lastly, the proposed learning system achieved classification accuracy of 90.23%, sensitivity of 98.00% and specificity of 96.65%.

Carers using assistive technology in dementia care at home: a mixed methods study

INTRODUCTION

Informal carers support persons with dementia to live at home, even with deteriorating physical, social and cognitive issues. This study aims to examine the experiences and impact of Assistive Technology (AT) on carers, providing care for a person with dementia.

METHODS

This is an explanatory sequential mixed methods study. The quantitative phase was an online and postal survey using the Carers Assistive Technology Experience Questionnaire and Short Form-12 (SF-12) questionnaire, with carers of persons with dementia in the UK, who used AT. The qualitative phase involved in-depth telephone interviews with a purposive sample of survey respondents and was analysed using hermeneutic phenomenology to develop, compare and explain the findings of the survey.

RESULTS

The survey included data from 201 carers. Smartphones (45.5%) and tablet computers (45.0%) were the most frequently used AT. Multiple AT were used in the care of persons with dementia predominantly for safety (78.5%), communication (66.0%), and reminders (62.5%). The SF-12 indicated that carers in the 46-65 age group and carers who were not extremely satisfied with AT had lower mental component scores whilst carers who lived with the person with dementia and older carers had lower physical component scores. Twenty-three carers participated in the interviews, and 5 themes with 14 sub-themes were identified. The interviews helped confirm data from the survey on the impact of AT on the physical, mental and social wellbeing of the carers. It helped describe reasons for satisfaction with AT; how AT was used in daily life and strengthened caring relationships and how wider support systems enhanced the care of a person with dementia using AT.

CONCLUSIONS

This study describes the use of AT in the real-world context. AT supplements the care provided to people with dementia in the community. Appropriate use, access to AT and abilities of the carer can enhance the support provided through AT to both carers and the person with dementia.

A pilot study of participatory and rapid implementation approaches to increase depression screening in primary care

BACKGROUND

Most individuals with depression go unidentified and untreated. In 2016 the US Preventive Services Task Force released guidelines recommending universal screening in primary care to identify patients with depression and to link them to treatment. Feasible, acceptable, and effective strategies to implement these guidelines are needed.

METHODS

This three-phased study employed rapid participatory methods to design and test strategies to increase depression screening at Penn Medicine, a large health system with 90 primary care practices. First, researchers solicited ideas and barriers from stakeholders to increase screening using an innovation tournament-a crowdsourcing method that invites stakeholders to submit ideas to address a workplace challenge. Second, a panel of stakeholders and scientists deliberated over and ranked the tournament ideas. An instant runoff election was held to select the winning idea. Third, the research team piloted the winning idea in a primary care practice using rapid prototyping, an approach that quickly refines and iterates strategy designs.

RESULTS

The innovation tournament yielded 31 ideas and 32 barriers from diverse stakeholders (12 primary care physicians, 10 medical assistants, 4 nurse practitioners, 2 practice managers, and 4 patient support assistants). A panel of 6 stakeholders and scientists deliberated on the ideas and voted for patient self-report (i.e., through tablet computers, text message, or an online patient portal) as the winning idea. The research team rapid prototyped tablets in one primary care practice with one physician over 5 five-hour shifts to examine the feasibility, acceptability, and effectiveness of the strategy. Most patients, the physician, and medical assistants found the tablets acceptable and feasible. However, patient support assistants struggled to incorporate them in their workflow and expressed concerns about scaling up the process. Depression screening rates were higher using tablets compared to usual care; follow-up was comparable between tablets and usual care.

CONCLUSIONS

Rapid participatory methods engaged and amplified the voices of diverse stakeholders in primary care. These methods helped design an acceptable and feasible implementation strategy that showed promise for increasing depression screening in a primary care setting. The next step is to evaluate the strategy in a randomized controlled trial across primary care practices.

Carers' experiences of assistive technology use in dementia care: a cross sectional survey

Background

Assistive Technology (AT) supports persons with dementia and their carers (family, friends and neighbours), yet little is known about experiences and the impact of AT on carers. We report on an exploratory survey that examined the types, uses, costs and impact of AT on carers as well as their quality of life.

Methods

A cross-sectional survey using the Carers Assistive Technology Experience Questionnaire collected data from carers in the UK, who used at least one AT in the previous year and provided more than 10 h of care for a person with dementia, living at home. Carers completed the questionnaire online or on paper and information on AT, socio-demographic details, and Short-Form Health Survey (SF-12) data were collected. Descriptive and inferential statistics were used to report results and draw conclusions.

Results

Data from 201 carers was analysed. Smartphones and tablet computers were the most frequently used AT. AT were used predominantly for safety, communication, and reminders. Carers usually make decisions on buying and continued use of AT. Multiple AT devices were used in the care of persons with dementia and number of AT used was associated with perceived satisfaction. Satisfaction with AT was not related to age, living arrangements and relationship of carers. From the SF-12, Mean Physical Component Score was 49.19 (95%CI- 47.75 to 50.63) and Mental Component Score was 45.37 (95%CI- 43.93 to 46.80). Women, carers in the 46–65 age group and carers who were not extremely satisfied with AT had lower MCS scores. Carers who lived with the person with dementia and older carers had lower PCS scores.

Conclusions

Carers report that AT has a beneficial impact. Carers use multiple ATs, perceive AT to be satisfactory and recommend AT use to others. To support carers, we recommend establishment of centrally funded information sources and a loan store for AT. Further research on incremental addition of AT and changes to formal/paid care because of using AT should be undertaken. Practitioners, academics, manufactures and policy makers should consider the experiences of carers in research, development and use of AT to facilitate improved community living of people with dementia.
