Interactive Assessments of CT (IACT): Digital Interactive Logic Puzzles to Assess Computational Thinking in Grades 3–8

Background and Context: The Inclusive Assessment of Computational Thinking (CT) designed for accessibility and learner variability was studied in over 50 classes in US schools (grades 3-8).
 Objective: The validation studies of IACT sampled thousands of students to establish IACT’s construct and concurrent validity as well as test-retest reliability.
 Method: IACT items for each CT practice were correlated to examine construct validity. The CT pre-measures were correlated with post-measures to examine test-retest reliability. The CT post-measures were correlated with external measures to examine concurrent validity.
 Findings: IACT studies showed moderate evidence of test-retest reliability and concurrent validity and low to moderate evidence of construct validity for an aggregated measure of CT, but weaker validity and reliability evidence for individual CT practices. These findings were similar for students with and without IEPs or 504s.
 Implications: IACT is the first CT tool for grades 3-8 that has been validated in a large-scale study among students with and without IEPs or 504s. While improvements are needed for stronger validity, it is a promising start.

Validation of two simple patient-centered outcome measures for virtual monitoring of patients with idiopathic inflammatory myositis.

BackgroundTelemedicine has changed the landscape of patient care with wider use of patient-centered outcome measures (PCOMs). We evaluated two novel task–based PCOMs namely ten times arm lift (AL) test and two-minute walk distance (2MWD) in idiopathic myositis (IIM).MethodsThis was a cross-sectional observational study with the enrolment of adult IIM (ACR/EULAR criteria) patients with active/inactive disease. Active disease was defined as any two of increase in immunosuppression within 3 months, elevated muscle enzymes, physician VAS ≥ 2, worsened cutaneous disease, or fall in MMT8 < 76. Standard myositis core set measures (CSMs) were evaluated and test–retest validity [Cronbach’s alfa (CA)], construct validity (Pearson’s correlation), and discriminant validity (between active/inactive IIM) were assessed. The results were further validated in a separate tele-rheumatology cohort.ResultsAmong 22 IIM patients (68%-female) of age 30.5(19–62) years, AL and 2MWD showed excellent test–retest reliability (CA-0.987, 0.99). AL exhibited moderate-strong correlation with all CSMs except CK levels and MDI. In contrast, 2MWD values were highly variable without CSM correlation. A higher AL time discriminated active and inactive myositis (16.6 vs 11 s, p = 0.006) with an AUC of 0.882 (p = 0.006). AL > 12.8 s had 94% negative predictive value (NPV) for active muscle disease. In the validation cohort (47 patient visits among 26 patients), AL significantly differentiated between active vs. inactive disease with an NPV of 95%.ConclusionsAL test exhibits pilot evidence of construct and discriminant validity in patients with IIM requiring further evaluation. 2MWD was not a good test for outcome evaluation of IIM patients. Key Points• Novel task–based patient-centered outcome measures were evaluated for remote monitoring of muscle strength in IIM.• Ten times arm lift (AL) test showed strong test–retest reliability as well as provide pilot evidence of construct and discriminant validity in patients with IIM unlike 2-min walk distance.• This provides preliminary evidence to further evaluate the role of AL as patient-centered outcome measure in patients with IIM for virtual clinical trials.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10067-021-05990-3.

Development and psychometric properties of the Knowledge and Attitudes to Mental Health Scales (KAMHS): a psychometric measure of mental health literacy in children and adolescents

BackgroundAdolescence is a crucial period for the acquisition of good mental health behaviours, which are the foundation for health and wellbeing in later life. Improved knowledge about mental health and improved help-seeking behaviours have been shown to lead to better mental health outcomes. Mental health literacy (MHL) is multifaceted (e.g., knowledge about symptoms, the stigma around mental health, good mental health practices, etc.). Measures are needed that can assess these different aspects of MHL. Measurement of mental health literacy is currently limited due to a lack of reported psychometric instruments with known psychometric properties. Given that most mental health problems start in early adolescence, a scale is needed that is reliable and valid in this age group.MethodsThe development and validation of the psychometric instrument (termed the Knowledge and Attitudes to Mental Health Scales: KAMHS) entailed two phases: 1) item generation based on an evidence-based intervention programme: The Guide; and 2) item reduction through exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) for factor structure and psychometric assessment. Participants were 559 Year 9 pupils in secondary schools across Wales aged between 13 and 14 years.ResultsResults from the CFA indicated an acceptable fit of the model to the data. The KAMHS showed good internal constancy and moderate test-retest validity (.40–.64).ConclusionsThe final version of the KAMHS contains 50 items that are appropriate for use in children and adolescents. These results suggest that the KAMHS can be used over time to assess the efficacy of interventions aimed at increasing the mental health literacy of adolescent populations.

The Attitude towards Polypills Questionnaire (APPQ): a phase I-III development and validation study in patients with cerebrovascular disease.

Background and purposeThe polypill approach has been proposed to reduce patients’ pill burden, increase medication adherence and lower stroke incidence. However, little is known about patients’ attitudes towards polypills for cerebrovascular medication.MethodsBased on the European Organization for Research and Treatment of Cancer Quality of Life Group questionnaire development guidelines, a questionnaire to measure patients’ attitudes towards polypills for the secondary prevention of stroke (phase I–III) was developed. In phase I, issues were generated via literature review and interviews with patients and healthcare professionals. The issues were operationalized into items in phase II. In phase III the questionnaire was validated in a large single‐centre sample, and test–retest and internal validity were evaluated.ResultsIn phase I, 34 relevant issues were identified through literature search and interviews. Pre‐testing the questionnaire indicated high applicability and comprehensibility. The final Attitudes towards Polypills Questionnaire was tested in N = 260 patients and showed a two‐factor structure. The factors were labelled ‘concerns’ and ‘benefits’. The scales showed acceptable and good internal validity (concerns, Cronbach's α = 0.85; benefits, α = 0.93), but the scales’ test–retest validity was ambiguous. On a 0 to 3 rating scale, concerns were rated lower than benefits (mean 1.07, SD 0.69 vs. mean 1.87, SD 0.89).ConclusionsThe Attitudes towards Polypills Questionnaire showed high comprehensibility and content validity to assess German language patients’ attitudes towards a polypill medication. Our data and questionnaire may aid the implementation of polypill treatments in clinical practice and can be used in the design of future clinical trials on polypill therapy. Further validation of the questionnaire is advised.

The test-retest reliability, concurrent validity, and minimal detectable change of the L test in patients with total hip arthroplasty

BackgroundThe L test is a modified version of the timed up and go test (TUG) with an L-shaped walking path. The L test is more extensive than other performance tests, especially in turn direction and specific tasks. The study aimed to evaluate the test-retest reliability, concurrent validity, and minimal detectable change of the L test in patients with total hip arthroplasty (THA). A cross-sectional study was conducted with 33 unilateral and primary THA patients. The L test was performed twice with an interval of an hour on the same day for the test-retest reliability. Timed up and go test (TUG), five times sit to stand test (FTST), and Harris hip score (HHS) were carried out for the analysis of the concurrent validity of the L test.ResultsThe mean age of the participants was 74.6 ± 10.3 years. The ICC score of the L test was 0.992. Test-retest reliability was excellent. SEM95 and MDC95 values were 3.39 and 9.39, respectively. Both TUG and HHS were strongly correlated with the L test (r1 = 0.889, r2 = −0.568, p < 0.001). However, there was no significant correlation between FTST and L test (r = 0.024, p > 0.05).ConclusionsThe L test is valid and reliable performance measurement in patients with primary unilateral THA. MDC95 of the L test is an essential reference for clinicians in the rehabilitation follow-up process of THA patients.

Nomological Network of Dispositional Mindfulness: Evidence from MIDUS-II and MIDUS-III

While dispositional mindfulness is a popular construct in the field of positive psychology, its nomological network in the context of health and well-being is not well established. Our study addresses this limitation by examining the relationship between dispositional mindfulness and various health-related psychological constructs, including personality, social well-being, and affective states. Data for this study were gathered from the national longitudinal studies of health and well-being called Midlife in the United States (MIDUS-II and MIDUS-III). The nomological network analysis of dispositional mindfulness showed positive associations with both religiosity and overall well-being measures (e.g., Social Well-Being, Sympathy, Optimism, and Generativity) and negative associations with maladaptive tendencies (e.g., Pessimism, Aggression, Neuroticism, and Personal Constraints). Finally, test-retest validity was positively verified by significant correlations among the variables, spanning over ten years. Articulating a nomological network of dispositional mindfulness has important implications for future research and practice.&#x0D; &amp;nbsp;

Reliability and validity of the Hebrew version of the forgotten joint score for assessing the outcomes of total knee arthroplasty

BackgroundThis prospective study aimed to assess the reliability and validity of the Hebrew version of the forgotten joint score-12 in patients undergoing total knee arthroplasty, because it is going to be used in the Hebrew-speaking populations in Israel.MethodsThe English version of forgotten joint score-12 was translated into Hebrew version by using the standard procedures and in collaboration with its authors. The consecutive patients who had undergone total knee arthroplasty in a single hospital were asked to fill out the Hebrew version of forgotten joint score-12, Oxford knee score, Short Form 12, and visual analog scale. A random subgroup of 60 patients were then asked to fill out a second Hebrew version of forgotten joint score-12 at a minimum of 2-week interval. The reliability was assessed in terms of internal consistency, test-retest reliability and split-half reliability. The validity was measured in terms of the outcomes as mentioned above.ResultsA total of 102 patients participated in the study. The Hebrew version of forgotten joint score-12 showed high reliability. The internal consistency was excellent (Cronbachs’ α = 0.943) and test-retest reliability was high (Intraclass correlation = 0.97). The forgotten joint scores were correlated with the Oxford knee score, Short Form 12, and visual analog scale (r = 0.86, r = 0.72, and r=-0.8, respectively), indicating a high validity.ConclusionsThe Hebrew version of forgotten joint score-12 has excellent reliability, excellent test-retest reliability and good validity. It can be safely used for assessing outcomes of TKA.

Use of the Montreal Cognitive Assessment Thai Version to Discriminate Amnestic Mild Cognitive Impairment from Alzheimer’s Disease and Healthy Controls: Machine Learning Results

Background: The Montreal Cognitive Assessment (MoCA) is an effective and applicable screening instrument to confirm the diagnosis of amnestic mild cognitive impairment (aMCI) from patients with Alzheimer’s disease (AD) and healthy controls (HCs). Objectives: This study aimed to determine the reliability and validity of the following: (a) Thai translation of the MoCA (MoCA-Thai) and (b) delineate the key features of aMCI based on the MoCA subdomains. Methods: This study included 60 HCs, 61 aMCI patients, and 60 AD patients. The MoCA-Thai shows adequate psychometric properties including internal consistency, concurrent validity, test-retest validity, and inter-rater reliability. Results: The MoCA-Thai may be employed as a diagnostic criterion to make the diagnosis of aMCI, whereby aMCI patients are discriminated from HC with an area under the receiver-operating characteristic (AUC-ROC) curve of 0.813 and from AD patients with an AUC-ROC curve of 0.938. The best cutoff scores of the MoCA-Thai to discriminate aMCI from HC is ≤24 and from AD > 16. Neural network analysis showed that (a) aberrations in recall was the most important feature of aMCI versus HC with impairments in language and orientation being the second and third most important features and (b) aberrations in visuospatial skills and executive functions were the most important features of AD versus aMCI and that impairments in recall, language, and orientation but not attention, concentration, and working memory, further discriminated AD from aMCI. Conclusions: The MoCA-Thai is an appropriate cognitive assessment tool to be used in the Thai population for the diagnosis of aMCI and AD.

Validation of the French Version of the Fear of COVID-19 Scale and Its Associations with Depression, Anxiety, and Differential Emotions.

The COVID-19 crisis represents a global health concern, including mental health. Regarding the necessity to assess anxiety related to COVID-19, a scale was developed (Ahorsu et al., 2020). The goal of the present study was to validate the Fear of COVID-19 Scale (FCV-19S) in French (official language in 29 countries), and investigate its relationship with indicators of affective disturbances. The sample comprised 316 participants (271 females) recruited online during the French lockdown. They were from several regions of France. The FCV-19S underwent a forward-backward translation procedure. Its psychometric properties were evaluated with the confirmatory factor analysis (CFA). The French FCV-19S demonstrated a stable unidimensional structure with robust psychometric properties (strong internal consistency, good convergent and divergent validity, and good test-retest validity). With its robust psychometric properties in assessing the unidimensional construct of the fear of COVID-19, this scale will help to provide a better understanding of the relationship between emotions and psychological or psychiatric disorders during the pandemics in French-speaking countries.

Computerized Dual-Task Testing of Gait Visuomotor and Cognitive Functions in Parkinson's Disease: Test-Retest Reliability and Validity.

BackgroundMobility and cognitive impairments in Parkinson’s disease (PD) often coexist and are prognostic of adverse health events. Consequently, assessment and training that simultaneously address both gait function and cognition are important to consider in rehabilitation and promotion of healthy aging. For this purpose, a computer game-based rehabilitation treadmill platform (GRP) was developed for dual-task (DT) assessment and training.ObjectiveThe first objective was to establish the test-retest reliability of the GRP assessment protocol for DT gait, visuomotor and executive cognitive function in PD patients. The second objective was to examine the effect of task condition [single task (ST) vs. DT] and disease severity (stage 2 vs. stage 3) on gait, visuomotor and cognitive function.MethodsThirty individuals aged 55 to 70 years, diagnosed with PD; 15 each at Hoehn and Yahr scale stage 2 (PD-2) and 3 (PD-3) performed a series of computerized visuomotor and cognitive game tasks while sitting (ST) and during treadmill walking (DT). A treadmill instrumented with a pressure mat was used to record center of foot pressure and compute the average and coefficient of variation (COV) of step time, step length, and drift during 1-min, speed-controlled intervals. Visuomotor and cognitive game performance measures were quantified using custom software. Testing was conducted on two occasions, 1 week apart.ResultsWith few exceptions, the assessment protocol showed moderate to high intraclass correlation coefficient (ICC) values under both ST and DT conditions for the spatio-temporal gait measures (average and COV), as well as the visuomotor tracking and cognitive game performance measures. A significant decline in gait, visuomotor, and cognitive game performance measures was observed during DT compared to ST conditions, and in the PD-3 compared to PD-2 groups.ConclusionThe high to moderate ICC values along with the lack of systematic errors in the measures indicate that this tool has the ability to repeatedly record reliable DT interference (DTI) effects over time. The use of interactive digital media provides a flexible method to produce and evaluate DTI for a wide range of executive cognitive activities. This also proves to be a sensitive tool for tracking disease progression.Clinical Trial Registrationwww.ClinicalTrials.gov, identifier NCT03232996.

Development and validation of the suicidal behaviours questionnaire - autism spectrum conditions in a community sample of autistic, possibly autistic and non-autistic adults

BackgroundAutistic people and those with high autistic traits are at high risk of experiencing suicidality. Yet, there are no suicidality assessment tools developed or validated for these groups.MethodsA widely used and validated suicidality assessment tool developed for the general population (SBQ-R), was adapted using feedback from autistic adults, to create the Suicidal Behaviours Questionnaire—Autism Spectrum Conditions (SBQ-ASC). The adapted tool was refined through nine interviews, and an online survey with 251 autistic adults, to establish clarity and relevance of the items. Subsequently, 308 autistic, 113 possibly autistic, and 268 non-autistic adults completed the adapted tool online, alongside self-report measures of autistic traits (AQ), camouflaging autistic traits (CAT-Q), depression (PHQ-9), anxiety (ASA-A), thwarted belongingness and perceived burdensomeness (INQ-15), lifetime non-suicidal self-injury, and the original version of the suicidality assessment tool (SBQ-R). Analyses explored the appropriateness and measurement properties of the adapted tool between the groups.ResultsThere was evidence in support of content validity, structural validity, internal consistency, convergent and divergent validity, test–retest validity, sensitivity and specificity (for distinguishing those with or without lifetime experience of suicide attempt), and hypothesis testing of the adapted tool (SBQ-ASC) in each group. The structure of the SBQ-ASC was equivalent between autistic and possibly autistic adults, regardless of gender, or use of visual aids to help quantify abstract rating scales.LimitationsThe samples involved in the development and validation of the adapted tool were largely female, and largely diagnosed as autistic in adulthood, which limits the generalisability of results to the wider autistic population. The SBQ-ASC has been developed for use in research and is not recommended to assess risk of future suicide attempts and/or self-harm. The SBQ-ASC has been designed with and for autistic and possibly autistic adults, and is not appropriate to compare to non-autistic adults given measurement differences between these groups.ConclusionsThe SBQ-ASC is a brief self-report suicidality assessment tool, developed and validated with and for autistic adults, without co-occurring intellectual disability. The SBQ-ASC is appropriate for use in research to identify suicidal thoughts and behaviours in autistic and possibly autistic people, and model associations with risk and protective factors.

A reliability and validity study on upper limb range of motion measurement using mobile sensor compared with goniometers

Introduction: The use of tele-rehabilitation devices to aid physiotherapy has gained popularity in recent years. In particular, measuring limb range of motion with a wearable mobile sensor can facilitate rehabilitation therapies by providing more efficient progress monitoring and reducing clinicians’ workload. This study aimed to examine the test-retest reliability and validity of using a wearable mobile sensor to measure upper limb range of motion (ROM). Materials and methods: Participants were recruited by convenient sampling. They were instructed to perform four kinds of upper limb movements including shoulder flexion, abduction, external rotation and elbow flexion, from which the ROM was measured by Mobile sensors REBEE (XCLR8 Technologies) and a standard goniometer (Model 12-1000) in each movement. Each kind of movements and the two ROM measurements were performed twice for the evaluation of test-retest reliability using Intraclass Correlation Coefficients (ICC). Pearson's correlations were computed between the ROM measured by the mobile sensors and the goniometer in each movement to assess construct validities of the mobile sensors. The agreement (95% mean difference) between the two sets of measurement was illustrated by Bland-Altman plots. Results: Thirty-four asymptomatic young Asian adults (15 males) participated in this study (Mage ± SD, 24.2 ± 3.82 years). The ICC for the ROM measured by the sensors were between 0.94 and 0.99, p &lt;0.01 and for the goniometer measurements were between 0.95 and 0.98, p &lt;0.01 in the four movements, indicating excellent reliability in both measurement methods. The Pearson's correlation between the sensor’s and goniometric ROM measurements in four kinds of movements ranged from r =0.96 to 0.99, p &lt;0.01, indicating a very strong construct validity for using the mobile sensors to measure upper limb ROM. The mean difference between the two measurements ranged from 0.13 degrees to 7.6 degrees. Conclusions: The results demonstrated that measuring upper limb ROM using the mobile sensors by non-healthcare trained students were as reliable and valid as using the standard universal goniometers by healthcare trained students. The findings implied that the wearable mobile sensors possibly allow non-healthcare trained carers to measure clinically useful, reliable and valid upper limb ROM from patients, which may facilitate symptom monitoring and improve the efficiency of the rehabilitation process.

Validation of the internet addiction test (IAT) to Sinhalese and assessment of internet addiction among school children in Sri Lanka

AimsTo translate Young's Internet Addiction Test (IAT) to Sinhalese and validate for use in a Sri Lankan population. Following validation of the questionnaire, to use the validated questionnaire to assess the prevalence of internet addiction in a school going population in the Western province of Sri Lanka and identify characteristics of those addicted to the internet.BackgroundThe internet is widely used across the world and in Sri Lanka. Though essential for everyday life there are many negative aspects of internet use. Addiction to the internet is one such problem and identified to exist among the general population and students in other countries. The most common tool used to measure internet addiction is Young's internet addiction test. The phenomena of internet addiction has not been scientifically studied in Sri Lanka according to our knowledge.MethodA school-based cross-sectional analytical study conducted in two stages among students aged 15 to 19 years. In stage 1 of the study, 200 students were administered the Sinhalese translation of the IAT and internal consistency and test retest validity assessed. Once validation of the scale was established the translated scale was used on a sample of 2800 students to assess presence of internet addiction.ResultThe Sinhala translation of the Internet addiction test showed good reliability and validity The Chrohnbach's alpha value was 0.78 and Pearson correlation coefficient of 0.85 and therefore suitable to use in a Sinhalese speaking population in Sri Lanka.Internet addiction was identified among the study population. 8% of the entire study sample and 12.6% among those using the internet showed features of internet addiction. The majority of cases of internet addiction identified were mild 8.2% followed by moderate internet addiction in 3.6% and only 0.9 % having severe internet addiction. There were no significant demographic or internet use related features identified among those with internet users and those not addicted to the internet.ConclusionThis study demonstrated that the Sinhala translation of Young's IAT is suitable to assess internet addiction in Sri Lanka. It also identified that there are students in Sri Lanka who are addicted to the internet. This will possibly impact negatively on their lives at a crucial stage of development and have immediate as well as long term detrimental effects. More studies are required to identify characteristics of those who are addicted to the internet and to plan interventions.

COVID-19 Infection Stigma Scale: psychometric properties

BackgroundStigma has been noticed towards patients with COVID-19 in several regions of the world. This social discrimination has contributed to delay in diagnosis and treatment. Also, it may increase the suffering of the patients leading to poor outcome of the illness. Stigma can be assessed with the use of a valid and reliable instrument developed and adapted to our culture. Our objective was to analyze the psychometric properties of COVID-19 Infection Stigma Scale (CISS) for measuring the social stigma among patients with COVID-19 in Egypt. A cross-sectional study that included 182 COVID-19 patients was carried out. The reliability, the convergent validity, and the external and internal consistency of the scale were measured. Factor analysis was used to exclude the weak items.ResultsThe mean of the COVID-19 Infection Stigma Scale scores was 34.97±10.35 which was higher than 50% of the score. Absence of the floor and ceiling effects was observed. Cronbach’s alpha coefficient for scale reliability ranged from 0.75 to 0.94 with 0.82 for the total score. The convergent validity coefficients ranged from 0.36 to 0.63. Test-retest validity Pearson’s correlation coefficients ranged from 0.72 to 0.92 with 0.89 for the total score. The split half correlation coefficient was 0.86, and the reliability coefficient was 0.92. Both were acceptable correlation coefficients for internal consistency of the scale. Factor analysis showed two factors had latent root greater than 1. The rotated component matrix of the 2 factors revealed that all questions had r value more than 0.30, which means that no need to exclude any of them.ConclusionThe results showed that the COVID-19 Infection Stigma Scale is a valid and reliable instrument for the Egyptian people.

Psychometric Properties of the Infant Toddler Activity Card Sort.

The Infant Toddler Activity Card Sort (ITACS) is a new measure that engages caregivers in goal development by measuring participation in early childhood. Initial evaluation of the ITACS is required to assess its psychometric properties. To evaluate test-retest reliability, concurrent validity, and between-group differences of the ITACS. Caregivers (N = 208) of children 0-3 years, who were typically developing (TD) or had a developmental delay (DD), completed the ITACS and Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) with repeat assessment after 2 weeks later (n = 117). The ITACS demonstrated moderate concurrent validity with the PEDI-CAT. Children with DD had significantly more activity concerns on the ITACS than TD. Adequate test-retest reliability was not achieved. The ITACS is a useful tool for identifying caregiver concerns in activity engagement; interventions can be tailored to address concerns and increase participation in childhood routines.

Illness Expectations Assessment in People with Asthma: A Tool for Explicit and Implicit Beliefs.

BackgroundIllness expectations are cognitive schemas, both explicit and implicit, describing how symptoms are expected to be in the future. They can be particularly relevant to disease in a mind/body framework. Asthma is a condition in which the psychological aspects can highly influence the body, but no study has directly explored these specific expectations, and no dedicated assessment tools are available.MethodsWe developed a questionnaire to assess the illness expectations, together with an ad hoc version of the Implicit Association Test (IAT). We tested its factorial structure, and the internal and test–retest validity, recruiting a sample of 183 asthmatic people. We also explored the convergent validity and the correlations with objective and subjective clinical assessments.ResultsData suggested a three-factorial structure of the questionnaire into expectations about future symptoms, change in current health status, and rigidity of these expectations. The questionnaire showed good psychometric properties and strong associations with the other considered outcomes, including implicit expectations. The implicit evaluation, however, lacked test–retest reliability.ConclusionThe questionnaire is a valid tool to assess illness expectations in people with asthma. The two expectation scales are highly related, and the implicit expectations are moderately associated with the explicit ones. The lack of stability related to IAT results may reflect a lack of stability of the implicit expectations. The implications for the mind/body framework still need to be fully explored.

Development of Measures of Perceived Neighborhood Environmental Attributes Influencing, and Perceived Barriers to Engagement in, Healthy Behaviors for Older Chinese Immigrants to Australia.

Environmental correlates, barriers, and facilitators of physical activity, healthy eating, and socializing are understudied in older immigrants to developed countries. This study developed/adapted and validated measures of perceived barriers and neighborhood environmental characteristics related to these health-enhancing behaviors appropriate for older Chinese immigrants to Australia and similar Western countries. Older Chinese immigrants living in Melbourne (Australia) were recruited from neighborhoods varying in walkability and percentage of Chinese residents. Versions of the Neighborhood Environment for Healthy Aging–Chinese Immigrants to Australia (NEHA-CIA) questionnaire (20 subscales) and the Perceived Barriers to Health-Enhancing Behaviors questionnaire (four subscales) were developed from extant validated scales and information collected in formative qualitative research. Thirty-one participants took part in cognitive interviews aimed to pilot-test and refine the questionnaires. The modified questionnaires were administered to 52 participants twice, two weeks apart. Test-retest reliability (intraclass correlation coefficients), internal consistency (Cronbach’s α), and construct validity (associations with theoretically-relevant constructs) were examined. Most items and subscales of both questionnaires had good test-retest reliability and internal consistency, while the NEHA-CIA also showed good construct validity. Future studies need to further examine the construct validity of the questionnaire of perceived barriers and determine the factorial validity of both measures on large representative samples.

Development and testing of the Geriatric Care Assessment Practices (G-CAP) survey

BackgroundWhile the Resident Assessment Instrument-Home Care (RAI-HC) tool was designed to support comprehensive geriatric assessment in home care, it is more often used for service allocation and little is known about how point-of-care providers collect the information they need to plan and provide care. The purpose of this pilot study was to develop and test a survey to explore the geriatric care assessment practices of nurses, occupational therapists (OTs) and physiotherapists (PTs) in home care.MethodsLiterature review and expert consultation informed the development of the Geriatric Care Assessment Practices (G-CAP) survey—a 33 question, online, self-report tool exploring assessment and information-sharing methods, attitudes, knowledge, experience and demographic information. The survey was pilot tested at a single home care agency in Ontario, Canada (N = 27). Test-retest reliability (N = 20) and construct validity were explored.ResultsThe subscales of the G-CAP survey showed fair to good test-retest reliability within a population of interdisciplinary home care providers [ICC2 (A,1) (M ICC = 0.58) for continuous items; weighted kappa (M kappa = 0.63) for categorical items]. Statistically significant differences between OT, PT and nurse responses [M t = 3.0; M p = 0.01] and moderate correlations between predicted related items [M r = |0.39|] provide preliminary support for our hypotheses around survey construct validity in this population. Pilot participants indicated that they use their clinical judgment far more often than standardized assessment tools. Client input was indicated to be the most important source of information for goal-setting. Most pilot participants had heard of the RAI-HC; however, few used it. Pilot participants agreed they could use assessment information from others but also said they must conduct their own assessments and only sometimes share and rarely receive information from other providers.ConclusionsThe G-CAP survey shows promise as a measure of the geriatric care assessment practices of interdisciplinary home care providers. Findings from the survey have the potential to inform improvements to integrated care planning. Next steps include making adaptations to the G-CAP survey to further improve the reliability and validity of the tool and a broad administration of the survey in Ontario home care.

Psychometric properties of the Multi-group Ethnic Identity Measure (MEIM) in a sample of Iranian young adults.

BackgroundThis study examines the factor structure, reliability and test-retest validity of the 12-item Iranian version of the Multigroup Ethnic Identity Measure (MEIM). Additionally, the MEIM’s concurrent validity was tested by investigating the association between ethnic identity and subjective well-being.MethodThe scale was translated into Persian language and was administered to 426 students (193 female) at a major public university in Tehran along with the Positive Affect Negative Affect Schedule, and the Satisfaction with Life Scale.ResultsThe confirmatory factor analysis supported the two-factor first-order commitment, and exploration (consisting of 12 items), and the second-order unidimensional factor structure of general ethnic identity. Moreover, we found evidence for good internal consistency, test re-test reliability, and concurrent validity.ConclusionThe MEIM Persian version was found to be a valid and reliable measure to examine ethnic identity in this Iranian student population, for both males and females. These results support the utility of the Persian version of the MEIM for its use in Middle-Eastern contexts.

Development of a Balance Recovery Performance Measure for Gait Perturbation Training Based on the Center of Pressure.

Background: The availability of instrumented treadmills that can apply unexpected perturbations during walking has made gait perturbation training more popular in clinical practice. To quantify and monitor balance recovery while training, easy to use measures are needed and may be based on integrated force plate data. Therefore, we aimed to quantify and evaluate different implementations of the recovery performance measure based on center of pressure data.Methods: Recovery performance was calculated based on differences in center of pressure trajectories between unperturbed walking and balance recovery after a perturbation. Five methodological choices leading to 36 different implementations were evaluated. Test-retest reliability, effect sizes, and concurrent validity were evaluated against trunk velocity measures.Results: Differences in measures of (dis-)similarity, time normalization and reference data affected reliability, sensitivity and validity and none of the performance measure implementations based on center of pressure trajectories was superior on all criteria. Measures assessing perturbation effects on trunk velocities provided more reliable and sensitive recovery outcomes.Discussion: Different implementations of the recovery performance measure can be chosen dependent on constraints imposed in the clinical setting.Conclusion: Quantifying recovery performance based on center of pressure data is possible and may be suitable to monitor improvement in recovery performance after gait perturbations in specific clinical setups. Validity of performance measures in general requires further attention.
