Objectives: To provide an overview of the methodological considerations for conducting commercial smartphone health app reviews (mHealth reviews), with the aim of systematising the process and supporting high-quality evaluations of mHealth apps. Design: Synthesis of our research team’s experiences of conducting and publishing various reviews of mHealth apps and hand-searching the top medical informatics journals (e.g., The Lancet Digital Health, npj Digital Medicine, Journal of Biomedical Informatics, and the Journal of the American Medical Informatics Association) over the last five years (2018-2022) to identify other app reviews to contribute to the discussion of this method and supporting framework for developing a research (review) question and determining the eligibility criteria. Results: We present seven steps to support rigour in conducting app reviews in health: 1) writing a research question, 2) conducting scoping searches and developing the protocol, 3) determining the eligibility criteria using the TECH framework, 4) conducting the final search and screening of health apps, 5) data extraction, 6) quality, functionality, and other assessments and 7) analysis and synthesis of findings. We introduce the novel TECH approach to developing review questions and the eligibility criteria, which considers the Target user, Evaluation focus, Connectedness, and the Health domain. Patient and public involvement and engagement opportunities are acknowledged, including co-developing the protocol and undertaking quality or usability assessments. Conclusion: Commercial mHealth app reviews can provide important insights into the health app market, including the availability of apps and their quality and functionality. We have outlined seven key steps for conducting rigorous health app reviews in addition to the TECH acronym, which can support researchers in writing research questions and determining the eligibility criteria. Future work will include a collaborative effort to develop reporting guidelines and a quality appraisal tool to ensure transparency and quality in systematic app reviews.

IntroductionPrevalence of possible sarcopenia is estimated to be significantly higher in community-dwelling older adults than that of confirmed or severe sarcopenia. However, there are currently far fewer non-pharmacological intervention strategies for possible sarcopenia than for sarcopenia in the community. Meanwhile, one type of non-pharmacological intervention in sarcopenic area, health education, is under-researched, and older people’s awareness about sarcopenia is extremely low, necessitating an immediate dissemination tool for prevention. Social media may be a potential, scalable, low-cost tool for this. This study protocol outlines how a social media-based multicomponent intervention will be co-designed with stakeholders to address this evidence gap.Methods and analysisGuided by the Medical Research Council’s framework, the proposed research covers two phases that employ a co-design approach to develop a theory-based multicomponent intervention to increase sarcopenia prevention in the community. The participants will be recruited from young-old adults (60∼69) with possible sarcopenia in the community of Changsha, China. Maximum sample size will be 45 participants in total, with 18∼25 participants in the development phase and 15∼20 participants in the pre-testing phase. During two rounds of focus groups with older adults, a social-media based intervention strategy will be developed from a theory-based conceptual model and an initial intervention plan formulated by the research group. After this, there will be a three-week pre-testing phase, followed by a semi-structured interview to further modify the theory-based conceptual model and the social-media based intervention strategy. The focus of the data analysis will be on thematic analysis of qualitative data primarily derived from the group interview and the semi-structured interview with key stakeholders.Ethics and disseminationThis study has been approved by the University of Manchester Research Ethics Committee (Project ID: 15664), and permissions have already been granted by collaborators in relevant Chinese organisations. We will collaborate with stakeholders to inform our dissemination strategy and co-present our findings (e.g., at community events or through social media). Furthermore, we will disseminate our findings to academics and healthcare professionals via webinars, academic conferences, and peer-reviewed publications.Strengths and limitations of this study-This is the first study to develop a health education and exercise intervention aimed at improving muscle function in community-dwelling young-old adults with possible sarcopenia.-This is the first study in the sarcopenic area to develop a multicomponent intervention for sarcopenia prevention based on social media (TikTok).-This study addresses some shortcomings of single text or audio materials or lengthy lessons in current health education for sarcopenia with short videos.-This study employs co-design to ensure that the intervention strategy is acceptable to relevant stakeholders and meets their needs by soliciting their input.-The sample size will be small that it may not be representative of the entire Chinese older population.-This study will not draw any conclusions about the intervention effectiveness due to the short duration of the pre-testing phase.-The study findings are unique to the community setting and population in China and may not be generalised to other settings or countries.

Background The 16-item Falls Efficacy Scale International (FES-I) is widely used to assess concerns-about-falling. Variants include 7-item Short FES-I, 30-item Iconographical Falls Efficacy Scale (Icon FES) and 10-item short Icon FES. No comprehensive systematic review and meta-analysis has been conducted to synthesise evidence regarding the measurement properties of these tools. Objectives To conduct a systematic review and meta-analysis of the measurement properties of four FES-I variants. Methods MEDLINE, Embase, CINAHL Plus, PsycINFO and Web of Science were searched systematically and articles were assessed for eligibility independently. The methodological quality of eligible studies was assessed using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. The quality of measurement properties was assessed using COSMIN criteria for good measurement properties. Where possible, meta-analysis was conducted; otherwise, narrative synthesis was performed. Overall certainty of evidence was rated using a modified Grading of Recommendations, Assessment, Development and Evaluation system approach. Results The review included 58 studies investigating measurement properties of the four instruments. There was high-quality evidence to support internal consistency, reliability and construct validity of all instruments. Moderate- to high-certainty evidence suggests one-factor structure of FES-I with two underlying dimensions, one-factor structure of Short FES-I and two-factor structure of Icon FES. There was high-certainty evidence to support the responsiveness of FES-I, with further research needed for the other instruments. Conclusion There is evidence for excellent measurement properties of all four instruments. We recommend the use of these tools with healthy older people and people at a greater risk of falls due to conditions that might affect mobility and balance.

IntroductionEarly prevention of sarcopenia is a recommendation to reduce morbidity, mortality and improve quality of life. Several non-pharmacological interventions to reduce the risk of sarcopenia in community-dwelling older people have been proposed. Therefore, there is a need to identify the scope and differences of these interventions. This scoping review will summarise the nature and extent of the existing literature that describes and examines non-pharmacological interventions for community-dwelling older adults with possible sarcopenia or sarcopenia.Methods and analysisThe seven-stage review methodology framework will be used. Searches will be conducted in the following databases: Embase, Medline, PsycINFO, CINAHL, All EBM Reviews, Web of Science, Scopus, CBM, CNKI, WANFANG and VIP. Grey literature will also be identified from Google scholar. Search dates will be restricted to January 2010 to December 2022, in English and Chinese language only. Screening will be focused on published research, including both quantitative and qualitative study designs, and prospectively registered trials. Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews will be followed when delineating the search decision process. Findings will be synthesised quantitatively and qualitatively as appropriate and classified using key conceptual categories. We will identify whether studies identified have been included in systematic reviews or meta-analyses, and research gaps and opportunities will be identified and summarised.Ethics and disseminationAs this is a review, ethical approval will not be sought. The results will be published in peer-reviewed scientific journals and also disseminated in relevant disease support groups and conferences. The planned scoping review will help us identify the current status of research and gaps in the literature, so as to develop a future research agenda.

BACKGROUND Physical activity leads to improvements in morbidity, mortality and quality of life, especially when it is progressive, challenging and regular. There is strong evidence that strength and balance exercises decrease the risk of falling. However, traditional exercises may be tedious and not very motivating for participants. Exergames have been found to increase engagement and enjoyment for older users. OBJECTIVE The aim of this study is to conduct a feasibility randomised controlled trail (RCT) on the use of MIRA Rehab exergames among older male residents in a care home setting in Saudi Arabia. METHODS With the goal of achieving a sample of 30 eligible participants. we will recruit 38 residents in the care home who will be randomly allocated to either the intervention or control group. The intervention participants will perform gamified exercises using the MIRA telerehabilitation platform (30 minutes three times per week for six weeks). The control group will receive educational advice based on OTAGO exercise programme booklets and be encouraged to exercise (30 minutes three times per week for six weeks). Participants will be assessed at Week 0, Week 6 and Week 12. Assessments will include feasibility measures (eligibility, recruitment and attrition rates, and practicalities of data collection methods) and participant outcome measures (balance, strength, mobility, adherence, quality of life, fear of falling, depression, acceptability and usability). RESULTS NA CONCLUSIONS Based on this feasibility RCT, we will design a definitive RCT to test whether the MIRA Rehab exergame programme benefits older people in Saudi Arabia who may not like participating in traditional exercise programmes and may be unwilling or unable to leave their homes. CLINICALTRIAL Feasibility RCT is not required for registration

ObjectiveTo formatively evaluate the Make Movement Your Mission (MMYM) digital health initiative to promote physical activity (PA) levels and help avert the negative consequences of sedentary behaviours in older adults during the SARS-CoV2 pandemic.MethodsMixed-method study to explore activity levels, changes in physical function and Activities of Daily Living (ADLs), quality-of-life, social engagement, technology use, and accessibility. Survey data were analysed descriptively. Qualitative interviews were analysed using framework analysis.ResultsForty-one respondents completed the survey (Mean age 68.4 (8.9) years; 34 Female), 68% aged ≥ 65 years. Average attendance was 14.3 sessions per week (3.5 h). 73% had been with MMYM for >1 year, 90% reported they were engaging in more movement on a typical day, and 75% reported improvement in ability to perform moderate PA. Since starting MMYM, participation in activities targeting strength, balance and flexibility increased (by 48%, 73% and 75%, respectively). 83% met strength and 90% balance PA guidelines for health (≥ 2x per week). Between 18% and 53% of respondents reported improvements in ADLs, 53% reported better quality-of-life, and 28% increased use of the internet. Eight participants were interviewed (Mean age 70.7 (6.7) years; 7 Female). Activity levels were promoted by having direct support from the instructor through Facebook messages pre and post live sessions, having group expectation about quality and level of engagement, having a sense of control and encouragement from others, MMYMs regularity, choice around level of engagement and accessibility. Noticing short-term outcomes in balance and posture helped boost confidence and continued participation.ConclusionClinical trials need to robustly assess its effectiveness and acceptability.

Background the Pictorial Fit-Frail Scale (PFFS) was designed as a simple and practical approach to the identification of frailty. Objectives To investigate the feasibility and reliability of this visual image-based tool, when used by patients, caregivers and healthcare professionals (HCPs) in clinical settings. Design observational study. Setting three outpatient geriatric healthcare settings. Subjects patients (n = 132), caregivers (n = 84), clinic nurses (n = 7) and physicians (n = 10). Methods the PFFS was administered to all patients. Where available, HCPs and caregivers completed the scale based on the patients’ health. In the geriatric day hospital, the PFFS was completed on admission and administered again within 7–14 days. Time and level of assistance needed to complete the scale were recorded. Intraclass correlation coefficients (ICCs) and 95% confidence intervals (CIs) were used to assess test−retest and inter-rater reliability. Results mean time to complete the scale (minutes:seconds ± SD) was 4:30 ± 1:54 for patients, 3:13 ± 1:34 for caregivers, 1:28 ± 0:57 for nurses and 1:32 ± 1:40 for physicians. Most patients were able to complete the scale unassisted (64%). Mean patient PFFS score was 11.1 ± 5.3, mean caregiver score was 13.2 ± 6.3, mean nurse score was 10.7 ± 4.5 and mean physician score was 11.1 ± 5.6; caregiver scores were significantly higher than patient (P Conclusion the PFFS is a feasible and reliable tool for use with patients, caregivers and HCPs in clinical settings. Further research on the validity and responsiveness of the tool is necessary.

Objective:To assess the feasibility, reliability, and validity of the Pictorial Fit-Frail Scale (PFFS) among patients, caregivers, nurses, and geriatricians in an outpatient memory clinic.Design:Observational study.Setting:A Canadian referral-based outpatient memory clinic.Participants:Fifty-one consecutive patients and/or their caregivers, as well as attending nurses and geriatricians.Measurements:Participants (patients, caregivers, nurses, and geriatricians) were asked to complete the PFFS based on the patient’s current level of functioning. Time-to-complete and level of assistance required was recorded. Participants also completed a demographic survey and patients’ medical history (including the Mini-Mental State Examination [MMSE], and Comprehensive Geriatric Assessment [CGA]) was obtained via chart review.Results:Patient participants had a mean age of 77.3±10.1 years, and average MMSE of 22.0±7.0, and 53% were female. Participants were able to complete the PFFS with minimal assistance, and their average times to completion were 4:38±2:09, 3:11±1:16, 1:05±0:19, and 0:57±0:30 (mins:sec) for patients, caregivers, nurses, and geriatricians, respectively. Mean PFFS scores as rated by patients, caregivers, nurses, and geriatricians were 9.0±5.7, 13.1±6.6, 11.2±4.5, 11.9±5.9, respectively. Patients with low MMSE scores (0–24) took significantly longer to complete the scale and had higher PFFS scores. Inter-rater reliability between nurses and geriatricians was 0.74, but it was lower when assessments were done for patients with low MMSE scores (0.47, pConclusions:The PFFS is feasible, even among people with some slight cognitive impairment, though it may be less useful when patients with severe dementia administer it to themselves. Further, the PFFS may help inform clinicians about areas of concern as identified by patients, enabling them to contribute more to diagnostic and treatment decisions or helping with health tracking and care planning.

Objective:Cognitive reserve (CR) capacity can be viewed as the maximum processing potential of neural systems that support adaptive cognitive performance in age-related cognitive decline. CR is a complex construct that can only be measured indirectly. Proxy measures (e.g., psychosocial/lifestyle variables) are traditionally used to reflect CR. However, strong relationships have been observed between these measures and cognitive functions (e.g., executive function [EF], processing resources [PR], fluid/crystallized abilities); therefore, the organizational structure of indicators implicated in CR remains unclear. The objective of this study was to test a hypothetical, theoretical model of CR capacity that includes both traditional CR proxy indicators and measures of cognitive function [Satz et al. (2011).Journal of Clinical and Experimental Neuropsychology,33(1), 121–130], which remain, as yet, untested.Method:Construct validity of the model was investigated in healthy older adults through exploratory and confirmatory factor analysis (EFA and CFA) using data from the Maastricht Ageing Study (MAAS). A secondary CFA was conducted to validate the model using data from the Irish Longitudinal Study on Ageing (TILDA).Results:EFA and CFA in MAAS established a two-factor model comprising EF/PR and cumulative cognitive enrichment (CCE), which was further validated in a secondary analysis in TILDA. Convergent and discriminant validity was supported in MAAS (range ofR2= .228–.635; factor correlation confidence interval (CI) = .622, .740) and TILDA (range ofR2= .172–.899; factor correlation CI = .559, .624).Conclusions:A dual model of CR elucidated the relationships between hypothesized indicators of CR capacity and revealed a two-factor structure suggesting that both control (EF/PR) and representational processes (CCE) are involved in CR capacity.

BackgroundStandardized frailty assessments are needed for early iden-tification and treatment. We aimed to develop a frailty scale using visual images, the Pictorial Fit-Frail Scale (PFFS), and to examine its feasibility and content validity.MethodsIn Phase 1, a multidisciplinary team identified domains for measurement, operationalized impairment levels, and re-viewed visual languages for the scale. In Phase 2, feedback was sought from health professionals and the general public. In Phase 3, 366 participants completed preliminary testing on the revised draft, including 162 UK paramedics, and rated the scale on feasibility and usability. In Phase 4, following translation into Malay, the final prototype was tested in 95 participants in Peninsular Malaysia and Borneo.ResultsThe final scale incorporated 14 domains, each conceptual-ized with 3–6 response levels. All domains were rated as “understood well” by most participants (range 64–94%). Percentage agreement with positive statements regarding appearance, feasibility, and usefulness ranged from 66% to 95%. Overall feedback from health-care professionals sup-ported its content validity.ConclusionsThe PFFS is comprehensive, feasible, and appears gener-alizable across countries, and has face and content validity. Investigation into the reliability and predictive validity of the scale is currently underway.

BACKGROUND Older people are at increased risk of adverse health events because of reduced physical activity. There is concern that activity levels are further reduced in the context of the COVID-19 pandemic, as many older people are practicing physical and social distancing to minimize transmission. Mobile health (mHealth) and eHealth technologies may offer a means by which older people can engage in physical activity while physically distancing. OBJECTIVE The objective of this study was to assess the evidence for mHealth or eHealth technology in the promotion of physical activity among older people aged 50 years or older. METHODS We conducted a rapid review of reviews using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched for systematic reviews published in the English language in 3 electronic databases: MEDLINE, CINAHL Plus, and Scopus. Two reviewers used predefined inclusion criteria to select relevant reviews and extracted data on review characteristics and intervention effectiveness. Two independent raters assessed review quality using the AMSTAR-2 tool. RESULTS Titles and abstracts (n=472) were screened, and 14 full-text reviews were assessed for eligibility. Initially, we included 5 reviews but excluded 1 from the narrative as it was judged to be of critically low quality. Three reviews concluded that mHealth or eHealth interventions were effective in increasing physical activity. One review found that the evidence was inconclusive. CONCLUSIONS There is low to moderate evidence that interventions delivered via mHealth or eHealth approaches may be effective in increasing physical activity in older adults in the short term. Components of successful interventions include self-monitoring, incorporation of theory and behavior change techniques, and social and professional support.

Background Goal Attainment Scaling (GAS) is an individualized outcome measure that allows the setting of personalized treatment goals. We compared the responsiveness of GAS when individuals set only one goal instead of the recommended three or more goals. Methods We conducted exploratory analyses on data from two randomized controlled trials: the Video-Imaging Synthesis of Treating Alzheimer’s Disease (VISTA) (n = 130); and the Mobile Geriatric Assessment Team (MGAT) (n = 265). Independent t-tests and standardized response means (SRMs) were used to assess responsiveness of one- vs. multiple-goal GAS. Results In VISTA, clinician-rated multiple-goal GAS detected higher goal attainment in the intervention group (p = 0.01; SRM = 0.48). One-goal GAS, whether rated by patients or by clinicians, did not detect differences in goal attainment between groups (patient: p = 0.56, SRM = 0.10; clinician: p = 0.10, SRM = 0.29). In MGAT, multiple-goal GAS (outcome goals: p p p p Conclusion One-goal GAS detected significant change in response to a patient-centred, multi-domain care initiative. As such, in similar contexts, one-goal GAS may be an effective means of optimizing personalization and improving GAS feasibility through reduced administration time. However, it is not yet clear if one-goal GAS is responsive in the context of a pharmacological intervention and further research is recommended.

Background: In people with dementia, neuropsychiatric symptoms (NPSs), especially agitation, are associated with worse quality of life and caregiver burden. As NPSs may vary with illness severity, knowledge of how people with dementia and their caregivers describe and rate the importance of agitation symptoms can improve the understanding of the clinical meaningfulness of the manifestations of agitation. The internet provides new opportunities to better understand patient experiences, as patients and caregivers increasingly look to Web-based platforms as a means of managing symptoms. Objective: The aim of this study was to examine Web-based reports from a dementia symptom website to better understand the symptoms of agitation and explore how they are being targeted for monitoring by caregivers of people with dementia. Methods: The Dementia Guide website hosts a Web-based database used by caregivers (97%) and people with dementia (3%). From its 61 dementia symptoms, users can select relevant symptoms that they deem important to monitor or track the effects of treatment. We employed a staging algorithm to determine if individuals had mild cognitive impairment (MCI) or mild, moderate, or severe dementia. Agitation was defined using terms consistent with the International Psychogeriatrics Association’s provisional consensus definition. We compared the proportion of people with NPSs and agitation across stages of dementia severity and studied how many agitation-defining descriptors were selected, and how often they occurred, by stage. Results: As of March 2017, 4121 people had used the tracking tool, of whom 2577 provided sufficient data to allow disease severity staging. NPSs were tracked by 2127/2577 (82.54%) and agitation by 1898/2577 (73.65%). The proportion in whom agitation was tracked increased with increasing cognitive impairment: 68.5% (491/717) in people with MCI, and 72.50% (754/1040), 73.3% (378/516), and 90.5% (275/304) in mild, moderate, and severe dementia, respectively (χ23=54.9; P

Purpose Guidelines for the use of goal attainment scaling (GAS) recommend that the patient specify at least three goals. Even so, this may not always be feasible or align with patient preferences. Investigations into the psychometric properties of GAS using three or more goals largely support its reliability, validity, and responsiveness compared with standard measures. As evaluations of responsiveness rely on variability estimates, this metric may be impacted when GAS is based on fewer than three goals. For this reason, we investigated the responsiveness of one- and two-goal GAS. Methods Secondary analyses were conducted on data from a mixed sample of pediatric, adolescent and adult subjects with hemophilia A. The standardized response mean (SRM) and its 95% confidence intervals (CI) were used to assess responsiveness of one- and two-goal GAS at six and twelve weeks. Results Both one-goal and two-goal GAS demonstrated similar responsiveness to change at 6-week (Patient-Rated GAS: one-goal SRM [95% CI] = 0.70 [0.45–1.08], two-goal = 0.96 [0.68–1.30]; Clinician-Rated GAS: one-goal = 1.26 [0.81–1.77], two-goal = 1.01 [0.73–1.32]) and 12-week follow-up (Patient-Rated GAS: one-goal SRM [95% CI] = 1.14 [0.53–1.71], two-goal = 1.35 [0.92–1.82]; Clinician-Rated GAS: one-goal = 1.71 [1.12–2.30], two-goal = 1.48 [1.02–2.02]). Larger SRMs were observed for clinician-rated GAS, but all were within the rubric of a large effect size. Conclusions One-goal GAS is responsive to change in a clinical population. Further research is recommended in a larger sample where responsiveness of one- and multiple-goal GAS can be compared

Objectives:Misplacing objects is often reported as a clinically important symptom in dementia. Here we explored misplacing objects in relation to dementia type and stage in an online sample of individuals with dementia and their caregivers.Methods:Participants were recruited from www.dementiaguide.com, a web-based tracker for common dementia symptoms. Users provided information about symptoms that they selected as important for monitoring. We analysed cross-sectional data from respondents who tracked at least three symptoms, which allowed for staging dementia severity.Results:Of 2,775 users with three-plus symptoms, 787 (28%) identified misplacing objects for symptom tracking. Misplacing objects was monitored by users across all stages of dementia, but was more prevalent in mild and severe dementia. Three common clinical subtypes of misplacing were investigated: lost & found (forgetting the location of items), hidden away (hiding items so others would not find them), and odd places (putting items in usual spots). Of the 787, 96% targeted lost & found, the most frequent type. Odd places (targeted in 56%) significantly increased with dementia severity (p < 0.001). Misplacing objects was most strongly associated with the symptoms of interaction with strangers (OR 4.60, 95% CI: 3.20-6.62), reading (3.68: 2.86-4.73), shopping (3.55: 2.73-4.61) and travel/vacationing (3.31: 2.54-4.31).Conclusions:Misplacing objects was most often selected for tracking in mild and severe stages of dementia. As disease advances, misplacing more often reflects odd placement of objects rather than their simple loss. Misplacing objects may be a clinically important therapeutic target for improving patients’ quality of life and lessening caregiver burden.

The Child and Youth Resilience Measure (CYRM) is one of the most popular measures of resilience. In this paper, we investigate the CYRM using Rasch analysis to explore and improve its psychometric properties, leading to a more robust measure of resilience.Cross-sectional data were obtained from a questionnaire administered to n = 408 individuals in Canada aged 11-19 who were participating in the Pathways to Resilience study. Rasch analysis was applied to these data, resulting in the production of a 17-item, 2-subscale CYRM-R, consisting of intra/interpersonal and caregiver resilience subscales. The subscales demonstrated good fit to the Rasch model by satisfying requirements of unidimensionality, good fit statistics and internal reliability, and a lack of item bias and problematic local dependency. The person separation indices also indicated that the subscales had good ability to differentiate between individuals of varying levels of resilience. In sum, the CYRM-R is a 2-subscale, 17-item Rasch-validated measure of resilience with robust psychometric properties. This revised measure is recommended for researchers and practitioners who are interested in measuring resilience across diverse cultures and contexts.

The recently developed Pictorial Fit-Frail Scale (PFFS) is an image-based tool that was designed to be easy to administer, sensitive to cultural differences, and a practical approach to identifying frailty compared to other frailty measures. The feasibility, reliability, validity, and responsiveness of the PFFS are currently being tested across three settings: geriatric day hospital (GDH), memory clinic, and primary care clinic. Preliminary analysis was conducted on data from all sites (n=80) to investigate the feasibility (time taken to complete the scale) and inter-rater reliability of the PFFS. Test-rest reliability was conducted on GDH data where patients attended at two time-points (retest within 7–14 days of initial visit; n=42). At all sites, when available, caregivers, nurses, and physicians completed the scale based on the patients’ health. PFFS scores can range from 0–43. A Frailty Index (FI) was constructed based on PFFS scores. Time taken to complete the scale was 4.9 ± 2.4 minutes for patients (n=46), 3.5 ± 1.4 for caregivers (n=43), 1.5 ± 1.1 for nurses (n=72), and 1.9 ± 2.0 for physicians (n=42). Mean patient PFFS score was 15.2 ± 7.0 (FI=0.36 ± 0.16), mean caregiver score was 19.9 ± 8.6 (FI=0.46 ± 0.20), mean nurse score was 15.4 ± 7.5 (FI=0.36 ± 0.18), and mean physician score was 19.2 ± 8.0 (FI=0.44 ± 0.18). There was no significant difference in scores between raters (p>.05). Test-retest reliability was good for patients (ICC=0.70) and nurses (ICC=0.80). Inter-rater reliability between patients/caregivers (ICC=0.83) and nurses/physicians (ICC=0.87) was good. Preliminary findings suggest the PFFS is a feasible and reliable tool, however further analysis is necessary with a larger sample.
