Gender and diagnostic impact on everyday technology use: a differential item functioning (DIF) analysis of the Everyday Technology Use Questionnaire (ETUQ)

Validity of the Brief Illness Perception Questionnaire in people with knee pain: a Rasch analysis

OBJECTIVE

The Brief Illness Perception Questionnaire (B-IPQ) is a frequently used measure of illness perception (IP). The aim of this study was to explore the psychometric properties of the questionnaire when used in elderly people with knee pain.

METHOD

Based on data from the Frederiksberg Cohort on elderly people reporting knee pain (N = 836), the psychometric properties of the eight B-IPQ items (1 'Consequences', 2 'Timeline', 3 'Personal control', 4 'Treatment control', 5 'Identity', 6 'Concern', 7 'Coherence', and 8 'Emotions') were analysed using Rasch analysis to establish whether the questionnaire provides reliable and valid measures of IP.

RESULTS

Threshold disordering was found on the 1-10 rating scale in all items. When rescaling to a 0-2 rating scale, disordering was resolved in six items. Item goodness-of-fit analyses revealed that two items displayed underfit misfit and four items overfit misfit; hence, the B-IPQ does not present unidimensionality. The person separation index indicated that items separate respondents into only two IP levels. Finally, floor and ceiling effects were found, indicating that the B-IPQ may not fully describe the extent of IP in this population.

CONCLUSION

The 1-10 rating scale used in the Danish B-IPQ targeting knee pain is suboptimal, while a 0-2 scale improves the psychometric properties of the scale. The B-IPQ does not present unidimensionality and the use of a sum score is therefore not recommended when assessing IP. The B-IPQ may not cover the extent of IP in elderly people with knee pain.

Measuring self-reported ability to perform activities of daily living: a Rasch analysis

Background

Since the number of persons diagnosed with multi-morbidity is increasing, there is a need for generic instruments to be able to assess, measure and compare ADL ability across diagnoses. Accordingly, the ADL-Interview (ADL-I) was developed to be used in rehabilitation research and clinical practice. The aim of this study was to investigate if the ADL-I can be used to provide valid and reliable ADL ability measures across gender and diagnostic groups.

Methods

ADL-I data were extracted from an existing research database on persons with chronic conditions including medical, rheumatological, oncological, neurological, geriatric and psychiatric diagnoses. Data were analysed based on Rasch Measurement methods to examine: the psychometric properties of the rating scale; ADL item and person fit to the Rasch model; if the difficulty of the ADL tasks differs across gender and diagnostic groups, and if the ADL-I provides precise and reliable measures of ADL ability.

Results

Data on n = 2098 persons were included in the final analysis. Initial evaluation of the 0–3 rating scale revealed threshold disordering between categories 1 and 2. After removal of 16 underfitting items, the variance explained by the Rasch dimension increased from 54.3 to 58.0%, thresholds were ordered, but the proportion of persons with misfitting ADL-I measures increased slightly from 8.7 to 9.1%. The person separation index improved slightly from 2.75 to 2.99 (reliability = 0.90). Differential test function analysis, however, supported that the 16 underfitting items did not represent a threat to the measurement system. Similarly, ADL items displaying differential item functioning across gender and diagnoses did not represent a threat to the measurement system. The ADL items and participants were well distributed along the scale, with item and person measures well targeted to each other, indicating a small ceiling effect and no floor effect.

Conclusions

The study results overall suggest that the ADL-I is producing valid and reliable measures across gender and diagnostic groups among persons within a broad range of ADL ability, providing evidence to support generic use of the ADL-I.

Strategies for Empowering activities in Everyday life (SEE 1.0): study protocol for a feasibility study of an Internet-based occupational therapy intervention for people with stroke

Background

Rehabilitation after stroke seldom focuses on needs related to an active everyday life and the process of change that people must undergo to adapt to an altered capacity and life situation. In particular, occupational therapy in the late phase needs to support clients in adopting sustainable self-initiated management strategies to regain daily activities and an active everyday life. To improve access to rehabilitation, the use of digital solutions has been suggested. This study aims to evaluate the feasibility of the Internet-based occupational therapy intervention “Strategies for Empowering activities in Everyday life” (SEE, version 1.0). We will investigate the feasibility of the intervention process in terms of acceptability and adherence as well as the most suitable outcome measures to evaluate SEE and improve the knowledge about the potential changes and outcomes of SEE for clients with stroke.

Methods

This feasibility study is based on a pretest posttest design without a control group. Quantitative and qualitative data will be collected from clients and staff concurrently embedded in a mixed-method design during the entire study.

Discussion

The project is a first test of a novel Internet-based occupational therapy intervention, and the research will contribute to the continued development and evaluation of the SEE programme. SEE can provide people with strategies in daily activities that can support them to live an active everyday life despite changed capacity and to improve access to rehabilitation interventions.

Female lens in urban mobility: technology-use behavior and individual differences

Purpose

The purpose of this study is to investigate how women's individual differences influence urban mobility service technology-use behavior. The reduction in urban mobility is a major problem in countries with emerging economies, thus affecting both the economy and quality of life.

Design/methodology/approach

The theoretical approach follows the individual differences theory of gender and information technology (IDTGIT). This research combines structured interviews to understand how the use of urban mobility service technology in daily routines is perceived, questionnaires to map individual differences and user demonstrations to capture how participants used mobility applications on their cell phones.

Findings

This study shows the influence of individual characteristics on the use of mobile apps and presents five behavioral profiles of women. This article goes beyond gender segregation to also show intragender differences.

Practical implications

This study explains women's behavior regarding urban mobility mobile applications through the generation of five profiles. These profiles can inform public policy managers on urban mobility and provide opportunities for improving the services of companies in the urban transport service chain.

Originality/value

With an intragender perspective, this study identifies the influence of individual characteristics on the use of technology and suggests that contextual identity, a novel dimension of characteristics that influence technology-use behavior, is relevant in the adoption of technology by its users.

Optimising the development of sustainable internet-based occupational therapy interventions: Important key actions and perspectives to consider

BACKGROUND

By examining the health needs of the general population and utilising the potential of digitalisation as a driving force, new internet-based services need to be developed in occupational therapy. However, existing guidelines for the development of complex interventions provide scant information on how to develop internet-based interventions.

AIM

The aim of this paper is to share experiences and illustrate important key actions and new perspectives to consider during the innovation process of developing and designing an internet-based occupational therapy intervention.

METHOD AND MATERIALS

International guidelines for intervention development was reviewed to add important perspectives in the innovation process.

RESULTS

The illustration focuses on five key actions in the development phase to highlight new perspectives and questions important to consider when designing new internet-based occupational therapy interventions.

CONCLUSION

The new perspectives can complement existing guidelines to enhance the development of more effective and sustainable internet-based interventions.

SIGNIFICANCE

The illustration provided has potential to improve the sustainability in innovation processes of new internet-based occupational therapy interventions.

Instrumental activities of daily living, amyloid, and cognition in cognitively normal older adults screening for the A4 Study

INTRODUCTION

We examined the associations among instrumental activities of daily living (IADL), cortical amyloid, and cognition in cognitively normal (CN) older adults.

METHODS

CN participants screening for the A4 Study (n = 4486) underwent florbetapir (amyloid) positron emission tomography. IADL were assessed using the Alzheimer's Disease Cooperative Study Activities of Daily Living Prevention Instrument. Separate logistic regression models were run with cortical amyloid or cognition as independent variable and IADL as dependent variable, adjusting for age and sex.

RESULTS

IADL difficulties were endorsed infrequently (≤16%). Overall IADL and four select IADL item difficulties ("remembering appointments," "finding belongings," "following TV programs," and "remembering current events") reported by both participant and study partner were significantly associated with greater amyloid burden and worse cognition.

DISCUSSION

Although IADL deficits were infrequent in this CN cohort, greater participant and study partner report of overall IADL deficits and subtle difficulties in specific IADL items were associated with mildly higher amyloid burden and worse cognition.

Does the purpose matter? A comparison of everyday information and communication technologies between eHealth use and general use as perceived by older adults with cognitive impairment

BACKGROUND AND OBJECTIVE

Everyday information and communication technologies (EICTs) are increasingly being used in our society, for both general and health-related purposes. This study aims to compare how older adults with cognitive impairment perceive relevance and level of EICT challenge between eHealth use and general use.

METHODS

This cross-sectional study includes 32 participants (65-85 years of age) with cognitive impairment of different origins (due to e.g., stroke or dementia). The Short Everyday Technology Use Questionnaire+ (S-ETUQ+) was used, providing information about the relevance of EICTs and measuring the EICT level of challenge. Data were analysed with descriptive statistics, standardized z-tests and Fisher's exact tests. The significance level was set to p < .05.

RESULTS

The result shows that the perceived amount of relevant EICTs for eHealth use was lower in all 16 EICTs compared to those of general use. About the perceived level of challenge, a significant difference was detected in one of the seven included EICTs between eHealth use and general use.

CONCLUSIONS

In this sample, all EICTs were perceived as having lower relevance for eHealth use compared to general use, suggesting that the purpose of using an EICT affects the perceived relevance of it. Also, once an EICT is perceived as relevant and used for eHealth purposes, there seem to be little to no differences in perceived challenge compared to the same EICT used for general purposes.Implications for rehabilitationAll stakeholders, including health care providers, need to be aware of the hindrances that come with digitalization, making it challenging to many citizens to make use of digital solutions.It is of great importance that social services including eHealth services be tailored to suit the individual/target group.Older adults may need support and an introduction to EICTs to discover the potential relevance of the specific device and/or service.

The perceived challenge of everyday technologies in Sweden, the United States and England: Exploring differential item functioning in the everyday technology use questionnaire

Background: The changing technological environment is reflected in regular updates made to the everyday technology (ET) use questionnaire (ETUQ). Newly added ETs may not present comparable challenges across countries and diagnoses.Aims: To identify whether country context, or dementia diagnosis, impact ETs' challenge level.Material and methods: 315 older adults from three countries were included; Sweden (n = 73), United States (n = 114), England (n = 128), and had a confirmed diagnosis of mild dementia (n = 99) or no known cognitive impairment (n = 216). Differential Items Functioning (DIF) analysis was performed on 88 ETs included in the ETUQ by country and diagnosis. The impact of DIF was evaluated in a Differential Test Functioning (DTF) analysis.Results: Nine items (10.2%) in the ETUQ showed statistically significant DIF between countries; five of which were public space ETs and none of which were information and communication technologies (ICTs). Three ICT items, and no others, showed significant DIF by diagnosis. The items' DIF was shown to have no impact upon person measures of ability to use ET in the DTF.Conclusions and significance: The utility of the ETUQ in occupational therapy practice and research internationally is highlighted through the stability of the challenge hierarchy and lack of impact on person measures.
