Adapting the Nurse Practitioner Primary Care Organizational Climate Questionnaire for Acute Care Nurse Practitioners.

Background and Purpose: This study adapted the Nurse Practitioner Primary Care Organizational Climate Questionnaire to measure the organizational climate of nurse practitioners in acute care settings and validated the Nurse Practitioner Acute Care Organizational Climate Questionnaire (NP-ACOCQ). Methods: We used a three-phase instrument adaptation design. In phase 1, experts assessed face and content validity. In phase 2, pilot testing enabled item analysis and preliminary reliability testing. In phase 3, field testing supported exploratory factor analysis. Results: The NP-ACOCQ had a three-factor structure representing subscales. The subscales had Cronbach's alphas of 0.87, 0.90, and 0.94. The subscales, Institutional Visibility, Interprofessional Relationships, and Organizational Autonomy each had between 5 and 13 items. Conclusions: The NP-ACOCQ is a valid and reliable measure to assess organizational factors determining the acute care nurse practitioner work environment.

Social and emotional competencies in Portuguese incarcerated males: psychometric properties of the SEC-Q questionnaire and their relation to health risk behaviors

This study departs from the acknowledged absence of validated measures to assess social and emotional competencies in incarcerated individuals. This is a critical gap given that most available programs aimed at fostering prosocial behavior and reducing antisocial behaviors are theoretically based on enhancing these competencies. This study assessed the psychometric properties of the Social and Emotional Competencies Questionnaire (SEC-Q) in a sample of 219 Portuguese incarcerated males (M age = 37.21 years, SD = 10.61), and to explore the impact of the SEC-Q dimensions on health risk behaviors in this population. The study used confirmatory factor analysis (CFA) to examine the factor structure of the SEC-Q. The four-factor model fitted well to the data (SB χ2 = 267.75; df = 120; Robust CFI = 0.99; Robust RMSEA = 0.06), and, as expected, it includes four dimensions: self-awareness, self-management and motivation, social awareness and prosocial behavior, and decision-making. The four dimensions showed appropriate internal consistency (Cronbach’s alpha = 74–81; McDonald’s omega = 75–82). Additionally, social and emotional competencies were related to higher self-control (rs=0.45, p <.01) and lower health risk behaviors (rs = − 0.25, p <.01), supporting convergent and divergent validity. Findings from the negative binomial regression suggest that higher social awareness and prosocial behavior is related to less health risk behaviors among incarcerated males. This study is a pivotal step to promote an affordable and valid measure to assess social and emotional competencies among Portuguese justice-involved males. SEC-Q can be an important complementary measure for evaluating the effectiveness of interventions aimed at preventing criminal recidivism.

An examination of teachers’ views on video games and learning: Establishing the Games and Literacy Education (GALE) scale

Teachers' views impact if and how technologies are integrated into classroom practice, and research demonstrates that digital game-based learning can support student learning across content areas. Yet, quantitative examinations of teachers' views on digital game-based learning in literacy education are limited. This study establishes the Gaming and Literacy Education (GALE) Scale as a reliable and valid measure for examining literacy teachers' perspectives on digital games and learning. The GALE Scale is a 21-item five-factor model created by conducting an exploratory factor analysis with survey data from 516 literacy teachers in the central United States followed by a confirmatory factor analysis with data from another 516 teachers. While participants generally agreed that digital games can support student learning, they reported limited integration of games in their classrooms, and only 12.2% agreed they learned about game-based learning in their teacher preparation program. Given the efficacy of digital game-based learning across disciplines demonstrated in meta-analytic research, literacy teacher education and professional development on effective uses of games in literacy learning are warranted. Further, scholars can utilize the GALE Scale to examine teachers’ views on digital games and literacy learning across time and contexts.

Reviewing the use of the Brief Religious Coping Scale (Brief RCOPE) across diverse cultures and populations

To discern the religious coping methods which individuals employ when confronting life stressors, Pargament devised the Religious Coping Scale (RCOPE) in 1997. Subsequently, in 1998, Pargament et al. formulated an abbreviated iteration, the Brief RCOPE, intended for both research and practical application. The Brief RCOPE has been found to be a reliable and valid measure, however much of the research looking into the psychometric properties of this measure has been conducted in the United States. The aim of the current review was to draw together findings from studies which have investigated the reliability and/or validity of the measure amongst populations outside of the United States. A narrative approach was adopted, involving searches of academic databases using keywords and the application of specific inclusion criteria. It was found that the reliability of the measure has been demonstrated across a number of countries, and across a range of different religions. The measure has also demonstrated good convergent, construct and concurrent validity in diverse cultures. The findings from this review suggest that the Brief RCOPE can be used in a range of diverse religions and cultures. However, more research is needed to ascertain the accuracy of the measure with other religions and cultures and with those in minority groups.

The Translation, Cross-Cultural Adaptation and Validation of the Italian Version of the Hip and Groin Outcome Score Questionnaire for a Young and Active Population.

The HAGOS (Hip and Groin Outcome Score) questionnaire is a valid and reliable measure of the self-assessment of symptoms, activity limitation, participation restriction, and quality of life (Qol) of subjects with hip and/or groin pain. The aims of this study are to translate and transculturally adapt the HAGOS into Italian (HAGOS-I) and to assess its internal consistency, validity, and reliability in physically active, young, and middle-aged subjects. The translation and transcultural adaptation of (HAGOS-I) was carried out according to international guidelines. Eight-one subjects (mean age 28.19) were included in this study. All the participants completed the HAGOS-I, the Lower Extremity Functional Scale (LEFS-I), the Oxford Hip Score (OHS-I), and the Short Form 36 Health Surveys (SF-36-I). The Cronbach's α for the six HAGOS subscales ranged from 0.63 to 0.87. Statistically significant correlations were obtained between the six HAGOS-I subscales and the LEFS-I (rs = 0.44-0.68; p < 0.01). Only one HAGOS-I subscale (Participation in Physical Activities) did not reach statistical significance with the OHS-I, while the remaining five had a moderate correlation (rs = 0.40-0.60; p < 0.01). The test-retest reliability (Intraclass Correlation Coefficient) ranged from 0.57 to 0.86 for the six HAGOS-I subscales. The HAGOS-I is a valid and reliable instrument that can be used in clinical settings with young and middle-aged subjects with hip and/or groin pathologies.

The psychometric properties of the Swahili version of the Primary Care Post Traumatic Stress Disorder screen for DSM-5 among adults in Kenya.

The psychometric properties of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) are undocumented in Kenya and sub-Saharan Africa (SSA) at large. This study aimed to evaluate the psychometric properties of the Swahili version of the tool, S-PC-PTSD-5, in a community sample of adults 18 years and older drawn from Nairobi, Mombasa and Kwale counties in Kenya. Analysis of cross-sectional data from 1431 adults from the community was conducted, examining the reliability, factorial structure, measurement invariance, and convergent and divergent validity of the interviewer-administered S-PC-PTSD-5. Out of 1431 adults who completed the S-PC-PTSD-5, 666 (46.5%) reported experiencing at least one traumatic event. Internal consistency of the S-PC-PTSD-5 was good overall, with alpha and omega values above 0.7. Confirmatory factor analysis (CFA) results indicated a one-factor structure of the S-PC-PTSD-5 for the overall sample. Multigroup CFA also demonstrated factorial invariance for sex for the one-factor structure of S-PC-PTSD-5. Scores for S-PC-PTSD-5 significantly correlated (positively) with those of generalized anxiety disorder (GAD7) and depressive symptoms (PHQ9), indicating convergent validity. S-PC-PTSD-5 scores also significantly correlated (negatively) with the WHO-5 wellbeing index, supporting divergent validity. The S-PC-PTSD-5 is a reliable and valid unidimensional measure. It appears to be a valuable screening measure for probable PTSD in both urban and rural community settings in Kenya. Nonetheless, to confidently identify those who may need treatment/additional support, further research on the reliability and validity of S-PC-PTSD-5 is required, especially its diagnostic accuracy at different cutoff scores.

Assessment of the reliability, responsiveness, and meaningfulness of the scale for the assessment and rating of ataxia (SARA) for lysosomal storage disorders.

To evaluate the reliability, responsiveness, and validity of theScale for the Assessment and Rating of Ataxia (SARA) in patients with lysosomal storage disorders (LSDs) who present with neurological symptoms, and quantify the threshold for a clinically meaningful change. We analyzed data from three clinical trial cohorts (IB1001-201, IB1001-202, and IB1001-301) of patients with Niemann-Pick disease type C (NPC) and GM2 Gangliosidoses (Tay-Sachs and Sandhoff disease) comprising 122 patients and 703 visits. Reproducibility was described as re-test reliability between repeat baseline visits or baseline and post-treatment washout visits. Responsiveness was determined in relation to the Investigator's, Caregiver's, and Patient's Clinical Global Impression of Improvement (CGI-I). The CGI-I data was also used to quantify a threshold for a clinically meaningful improvement on the SARA scale. Using a qualitative methods approach, patient/caregiver interviews from the IB1001-301 trial were further used to assess a threshold of meaningful change as well as the breadth of neurological signs and symptoms captured and evaluated by the SARA scale. The Inter-Class Correlation (ICC) was 0.95 or greater for all three trials, indicating a high internal consistency/reliability. The mean change in SARA between repeat baseline and post-treatment washout visit assessments in all trials was -0.05, SD 1.98, i.e., minimal, indicating no significant differences, learning effects or other systematic biases. For the CGI-I responses and change in SARA scores, Area Under the Curve (AUC) values were 0.82, 0.71, and 0.77 for the Investigator's, Caregiver's, and Patient's CGI-I respectively, indicating strong agreement. Further qualitative analyses of the patient/caregiver interviews demonstrated a 1-point or greater change on SARA to be a clinically meaningful improvement which is directly relevant to the patient's everyday functioning and quality of life. Changes captured by the SARA were also paralleled by improvement in a broad range of neurological signs and symptoms and beyond cerebellar ataxia. Qualitative and quantitative data demonstrate the reliability and responsiveness of the SARA score as a valid measure of neurological signs and symptoms in LSDs with CNS involvement, such as NPC and GM2 Gangliosidoses. A 1-point change represents a clinically meaningful transition reflecting the gain or loss of complex function.

Validity of the Addiction-like Eating Behavior Scale among Patients with Compulsive Eating.

Food addiction (FA) and binge eating disorder (BED) co-occur and share compulsive eating symptoms. When using an FA measure, it is important to evaluate its performance in a population presenting compulsive eating. The study aims to validate the Addiction-like Eating Behavior Scale (AEBS) among a clinical sample characterized by compulsive eating and overweight/obesity and to evaluate its incremental validity over the Yale Food Addiction Scale 2.0 (YFAS). Patients seeking help for compulsive eating (n = 220), between January 2020 and July 2023, completed online questionnaires, including FA, compulsive eating, and BMI evaluations. The factor structure, internal consistency, and convergent, divergent, and incremental validity were tested. The sample had a mean age of 44.4 years old (SD = 12.7) and a mean BMI of 38.2 (SD = 8.0). The two-factor structure provided a good fit for the data, with factor loadings from 0.55 to 0.82 (except for item 15) and the internal consistency was high (ω = 0.84-0.89). The AEBS was positively correlated with the YFAS (r = 0.66), binge eating (r = 0.67), grazing (r = 0.47), craving (r = 0.74), and BMI (r = 0.26), and negatively correlated with dietary restraint (r = -0.37), supporting good convergent and divergent validity. For each measure of compulsive eating, linear regression showed that the AEBS "appetite drive" subscale had a unique contribution over the YFAS. This study provided evidence that the AEBS is a valid measure among a clinical sample of patients with compulsive eating and overweight/obesity. However, questions remain as to whether the AEBS is a measure of FA or compulsive eating.

Perceptions of adults with type 1 diabetes toward diabetes-specific quality of life measures: a survey-based qualitative exploration

BackgroundDiabetes-specific quality of life (QoL) questionnaires are commonly used to assess the impact of diabetes and its management on an individual’s quality of life. While several valid and reliable measures of diabetes-specific QoL exist, there is no consensus on which to use and in what setting. Furthermore, there is limited evidence of their acceptability to people with diabetes. Our aim was to explore perceptions of adults with type 1 diabetes (T1D) toward five diabetes-specific QoL measures.MethodsAdults (aged 18 + years) with T1D living in Australia or the United Kingdom (UK) were eligible to take part in ‘YourSAY: QoL’, an online cross-sectional survey. Recruitment involved study promotion on diabetes-related websites and social media, as well as direct invitation of people with T1D via a hospital client list (UK only). In random order, participants completed five diabetes-specific QoL measures: Audit of Diabetes-Dependent Quality of Life (ADDQoL-19); Diabetes Care Profile: Social and Personal Factors subscale (DCP); DAWN Impact of Diabetes Profile (DIDP); Diabetes-Specific Quality of Life Scale: Burden Subscale (DSQoLS); Diabetes Quality of Life Questionnaire (Diabetes QOL-Q). They were invited to provide feedback on each questionnaire in the form of a brief free-text response. Responses were analysed using inductive, thematic template analysis.ResultsOf the N = 1,946 adults with T1D who completed the survey, 20% (UK: n = 216, Australia: n = 168) provided qualitative responses about ≥ 1 measure. All measures received both positive and negative feedback, across four themes: (1) clarity and ease of completion, e.g., difficulty isolating impact of diabetes, dislike of hypothetical questions, and preference for ‘not applicable’ response options; (2) relevance and comprehensiveness, e.g., inclusion of a wide range of aspects of life to improve personal relevance; (3) length and repetition, e.g., length to be balanced against respondent burden; (4) framing and tone, e.g., preference for respectful language and avoidance of extremes.ConclusionsThese findings suggest opportunities to improve the relevance and acceptability of existing diabetes-specific QoL measures, and offer considerations for developing new measures, which need to be better informed by the preferences of people living with diabetes.

New Psychometric Evidence of the Life Satisfaction Scale in Older Adults: An Exploratory Graph Analysis Approach.

The objective of the present study was to analyze the psychometric properties of a life satisfaction scale in older Peruvian adults using an exploratory graph analysis (EGA) approach. A total of 407 older adults aged between 60 and 95 years (M = 69.5; SD = 6.7) from three comprehensive elderly care centers (CIAMs) in Lima, Peru, were recruited. A non-probabilistic convenience sampling was used. The Satisfaction with Life Scale (SWLS) was analyzed using EGA with the Gaussian GLASSO model to assess its dimensionality and structural consistency. The relationship with other variables was analyzed using scales such as the GAD-7 and PHQ-9. The network structure of the SWLS indicates a single dimension. Additionally, network loadings (nodes) were examined, showing high values (>0.35) for most items except item 1, which had a moderate loading (>0.25). Structural reliability showed that a single dimension was identified 100% of the time. The post hoc CFA considering the unidimensional network structure obtained through EGA showed satisfactory fit (χ2/df = 3.48, CFI = 0.96, TLI = 0.92, SRMR = 0.02, RMSEA = 0.07 [90% CI 0.05, 0.08]). Finally, internal consistency reliability was acceptable (ω = 0.92). The SWLS measure is robust and consistent. These findings are a valuable reference for advancing research on aging in Peru, as they provide a practical, valid, and reliable measure.

Development and Validation of the Cheers Attitudes towards Non-drinkers Scale (CANS).

Non-drinkers report experiencing stigma, which can act as a barrier to non-drinking. Two studies were undertaken to develop and test a new scale to measure attitudes towards non-drinkers. In Study 1, 29 items were presented to 426 Australian drinkers. In Study 2, the refined 12-item Cheers Attitudes to Non-drinkers Scale (CANS) was presented to 389 drinkers. Alcohol consumption, Harm and the Regan Attitudes towards Non-drinkers Scale (RANDS) were presented for scale validation. Exploratory factor analysis revealed three factors representing the Threats to Fun, Connection and Self that drinkers perceive non-drinkers to pose. Confirmatory factor analysis showed that the scale meets the required fit indices and had good reliability (α = 0.842). Evidence of validity was shown through significant correlations with Alcohol Consumption, Harm and the RANDS. These studies show the CANS to be a reliable and valid measure that could be utilised to understand and modify the stigma experienced by non-drinkers.

Validity, Agreement and Reliability of the ForceFrame Dynamometer in Patients with Anterior Cruciate Ligament Injury.

Restoring maximal muscle strength of the knee extensors (KE) and knee flexors (KF) following anterior cruciate ligament (ACL) injury and ACL reconstruction is of great importance to reduce the re-injury rate after ACL reconstruction and to reduce the risk of knee osteoarthritis. Therefore, it is essential that clinicians and healthcare providers use valid and reliable measures to assess knee muscle strength to ensure a safe return to sport. To evaluate the reliability (test-retest reliability, inter-tester reliability and test-retest agreement) and validity (concurrent validity, convergent validity and ForceFrame (FF) vs.isokinetic dynamometer (ID) agreement) of the ForceFrame (FF) dynamometer during isometric testing of the knee extensors and flexors. Cross-sectional study. Twenty-seven participants with ACL injury or reconstruction were recruited for participation in this study. maximal voluntary isometric contration (MVIC) of the knee extensors and flexors was tested on two separate days. Day one included validity assessments with FF, a gold-standard ID and a handheld dynamometer (HHD). Day two included reliability assessments with FF performed by two assessors. Main outcome measures were day-to-day test-retest reliability and agreement and inter-tester reliability of FF, and concurrent validity (FF vs.an ID and a HHD). Reliability was tested as test-retest and inter-tester reliability using interclass correlation coefficient (ICC), while agreement was tested using Bland & Altman plots with limits of agreement (LOA), standard error of measurement (SEM) and smallest detectable change (SDC). Concurrent validity between FF, ID, and HHD was assessed using Pearson's correlations and mean difference was evaluated by Bland & Altman plots. Twenty-seven participants (10 females, 17 males) with a median age of 25 years (range 19-60) were included in this study. There was a good day-to-day test-retest reliability for MVIC of KE (ICC=0.77, CI95:0.48-0.90) and KF (ICC=0.83, CI95:0.61-0.92) and excellent inter-tester reliability for MVIC of KE (ICC=0.97, CI95:0.94-0.98) and KF (ICC=0.93, 95CI:0.85-0.97). Standard error of measurement (SEM) was 8% and 9%, while the smallest detectable change (SDC) was 22% and 27% for KE and KF, respectively. FF showed fair concurrent validity compared to ID for KE (r=0.56), poor concurrent validity for knee flexors (KF (r=0.24) and compared to HHD a moderate correlation for KE (r=0.74) and poor correlation for KF (r=0.12). Bland & Altman plots between FF and the ID showed a mean difference of -0.51 Nm/kg for KE and -0.32Nm/kg for KF. FF can be used to obtain reliable and valid results to assess MVIC of the KE, but not the KF. It should be noted that absolute results produced by the FF may be considered an underestimation of actual MVIC. The test position to assess KF in FF does not appear to be optimal, and different test-positions may be considered. Level 3.

Cognitive Distortion Scale for Bangladesh: Development and Properties

The purpose of the study was to develop a scale for assessing cognitive distortions in Bangladesh and establishing psychometric properties for Bangladeshi population. The scale was named as Bangladesh Cognitive Distortion Scale (BCDS). Items were constructed through three stages of intensive expert evaluation where 128 respondents participated and both item analysis and factor analysis were undertaken. Finalized BCDS with 39 items was administered to 478 respondents to calculate its psychometric properties. Concurrent validity of BCDS was found 0.828 by calculating correlation between the score of BCDS and clinician’s subjective rating. Predictive validity considering anxiety and depression scale was found 0.756 and 0.841, respectively. Convergent validity (0.670) was confirmed through the correlation between the DAS and BCDS and divergent validity was established by the discriminate value (F=649.564, α&lt;0.01) of clinical and non-clinical groups. Internal consistency reliability of BCDS (Cronbach Alpha- 0.962 and test-retest- 0.890) was found very high. The cut-off point for measuring cognitive distortion by BCDS was found 56 with sensitivity 87% and specificity 88%. According to the percentile norm, total score 56 to 72, 73 to 91, 92 to 109, 110 and above represents the mild, moderate, severe, and profound levels of cognitive distortions respectively. BCDS not only will help both clinicians and researchers to assess cognitive distortions within a short time but also could be used as a valid and reliable outcome measure in cognitive behavior therapy.

Tibial acceleration alone is not a valid surrogate measure of tibial load in response to stride length manipulation

PurposeThis study aimed to evaluate the relationship between peak tibial acceleration and peak ankle joint contact forces in response to stride length manipulation during level-ground running. MethodsTwenty-seven physically active participants ran 10 trials at preferred speed in each of 5 stride length conditions: preferred, ±5 %, and ±10 % of preferred stride length. Motion capture, force platform, and tibial acceleration data were directly measured, and ankle joint contact forces were estimated using an inverse-dynamics-based static optimization routine. ResultsIn general, peak axial tibial accelerations (p < 0.001) as well as axial (p < 0.001) and resultant (p < 0.001) ankle joint contact forces increased with stride length. When averaged within the 10 strides of each stride condition, moderate positive correlations were observed between peak axial acceleration and joint contact force (r = 0.49) as well as peak resultant acceleration and joint contact force (r = 0.51). However, 37% of participants illustrated either no relationship or negative correlations. Only weak correlations across participants existed between peak axial acceleration and joint contact force (r = 0.12) as well as peak resultant acceleration and ankle joint contact force (r = 0.18) when examined on a step-by-step basis. ConclusionThese results suggest that tibial acceleration should not be used as a surrogate for ankle joint contact force on a step-by-step basis in response to stride length manipulations during level-ground running. A 10-step averaged tibial acceleration metric may be useful for some runners, but an initial laboratory assessment would be required to identify these individuals.

Psychometric Properties of the Italian Version of the Interpersonal Sensitivity Measure (IPSM)

The Interpersonal Sensitivity Measure (IPSM) is used to assess interpersonal sensitivity. This study explored the factor structure, internal consistency, and criterion validity of the Italian version of the IPSM (IPSM-It) in non-clinical emerging adults. 374 participants aged between 18 and 31 years (64.4% female; M = 21.96, SD = 2.91) were included in the study. They completed the IPSM, the Beck Depression Inventory-I, the Beck Anxiety Inventory, the State-Trait Anger Expression Inventory-II, and the Satisfaction with Life Scale. Confirmatory factor analysis indicated that the original structure of the measure did not fit the data well. An exploratory factor analysis was also conducted and the results supported a 27-item version of the IPSM and a three-factor structure (Interpersonal Worry and Dependency, Low Self- Esteem, and Unassertive Interpersonal Behavior). The IPSM-It showed good internal consistency and criterion validity. The IPSM-It appeared to be a reliable and valid measure for assessing IPS in Italian culture.

The email conservation task: Testing the validity of an online measure of direct pro-environmental behavior

There is a need for valid measures of pro-environmental behavior, in particular ones measuring actual behavior. In response, a number of such measures have been introduced recently, however each faces limitations such as high costs, practical use and/or only measure indirect environmental behavior, limiting their scope, accessibility and inclusivity. In response, this study introduces the easily administered and low-cost Email Conservation Task (ECT), which measures direct pro-environmental behaviour (in this case, email use). Here, participants chose between personal costs (time spent on trivial tasks) or environmental costs (receiving unnecessary emails leading to CO2 emissions) across multiple trials. In a pre-registered study testing the validity of the ECT, it was found (as hypothesized) that participants scored higher on the ECT (incurred more personal costs rather than receiving unnecessary emails) when personal costs to them were lower, and scored higher when the environmental costs of receiving unnecessary emails were higher. Finally, total scores on the ECT significantly correlated with scores on three self-reported indicators of pro-environmentalism. Overall, the results of this study support all three hypotheses, indicating that the ECT is a valid measure of pro-environmental behavior that can be implemented across a diverse range of research areas.

Psychometric Evaluation of the Traumatic Grief Inventory-Self Report Plus (TGI-SR+) in Chinese Bereaved People.

The Traumatic Grief Inventory-Self Report Plus (TGI-SR+) measures the most recent prolonged grief disorder (PGD) symptom sets defined in the 11th edition of the International Statistical of Diseases and Related Health Problems (ICD-11) and the text revision of the fifth edition of the Diagnostical and Statistical Manual of Mental Disorders (DSM-5-TR). However, the TGI-SR+ has not yet been translated and validated in Chinese. This study aims to evaluate the psychometric properties of the Chinese translation of the TGI-SR+. We examined the Chinese TGI-SR+'s factor structure, internal consistency, convergent validity, discriminant validity, known-groups validity, and optimal clinical cut-off scores in 443 Chinese bereaved adults. Confirmatory factor analyses showed that the two-factor models showed the best fit for the Chinese TGI-SR+ items assessing ICD-11 and DSM-5-TR prolonged grief symptoms. Items assessing ICD-11 and DSM-5-TR prolonged grief symptoms demonstrated good internal consistency. Associations of TGI-SR+ scores with symptom levels of prolonged grief (assessed by the International Prolonged Grief Disorder Scale), posttraumatic stress, anxiety, and depression supported convergent and discriminant validity. Associations with background/loss-related variables provided evidence for known-groups validity. Cut-off points for probable ICD-11 PGD (liberal scoring rule), probable ICD-11 PGD (conservative scoring rule), and probable DSM-5-TR PGD were ≥67, ≥75, and ≥68, respectively. The Chinese TGI-SR+ appears to be a reliable and valid measure to assess prolonged grief symptoms per ICD-11 and DSM-5-TR among Chinese bereaved adults.

Measuring dimensions of teacher resilience in Africa: Self-efficacy and teacher efficacy

With this article we aimed to contribute evidence on reliable and valid measurement of teacher resilience in an under researched African context and population. Scales from an existing instrument, ENTREEi, were used to measure the resilience of pre-service teachers at a South African university. The sample constituted 1,193 final-year pre-service teachers (20–32 years), who completed the FIRE teacher resilience measure (2015 to 2017). Teacher resilience data were purposively selected from the FIRE dataset and items analysed related to self-efficacy and teacher efficacy beliefs. A quantitative approach was used, which consisted of reliability (internal consistency using Cronbach’s alpha) and validity (construct validity using Spearman correlations) analyses of the teacher resilience scale and the teacher efficacy scale. The statistical analyses indicate that the FIRE teacher resilience measure is a reliable and valid measure for intrapersonal resilience-enabling pathways in a challenged context. The underlying variable structure of the teacher resilience scale and teacher efficacy scale held in a Global South setting when used with pre-service teachers. The article contributes to teacher resilience measurement discourse by providing insights into the utility of teacher resilience scales in South Africa. The results act as a precursor for comparative teacher resilience results worldwide for future studies.

The Indian Geriatrics Quality of Life Inventory Scale (IGQOLI): Development and Validation of a Scale to Evaluate the Quality of Life among Geriatric Population of India.

Quality of life (QOL) refers to an individual's perception of their overall life and well-being. As people age, their QOL often deteriorates. Although various outcome measures exist to assess QOL, most are limited in scope and not specific to the Indian ethnicity of geriatrics. Therefore, a new outcome measure was developed and validated to more accurately evaluate the QOL for the geriatric population in India. The outcome measure was developed in three stages, followed by validation. Data was collected using multistage cluster sampling from 13 subdivisions of Jaipur district. A total of 423 participants were interviewed face-to-face. The collected data was analyzed using SPSS version 20, and the reliability and validity of the outcome measure were assessed. The Indian Geriatrics Quality of Life Inventory (IGQOL) scale demonstrated excellent reliability, with a Cronbach's alpha (α) of 0.95 and an intraclass correlation coefficient of 0.93. The measure also exhibited excellent face and content validity, with a K value of 1. Correlation analysis revealed a significant relationship with other outcome measures, with a Pearson correlation coefficient value of > 7 and a p-value of < 0.05. The study concludes that the IGQOLI scale is a reliable and valid outcome measure for evaluating the QOL in the geriatric population in India.

Feasibility of Using Standardized Outcome Measures in the Remote Assessment of Patients with Chronic Stroke: A Case Series

Introduction: With the increase of telerehabilitation utilization worldwide after the COVID-19 pandemic, a review of the current literature shows a concurrent increase in telerehabilitation studies focusing on interventions and delivery models. There is a gap in research on valid and reliable tests and measures that can be used in the physical therapy examination of people with stroke via telerehabilitation. Current reports on psychometric properties of most standardized outcome measures are only applicable in an in-person setting and may not be directly applicable in a remote setting where various challenges contribute to the reliability of results. This report describes the feasibility of administering selected standardized outcome measures in the remote assessment of three patients with chronic stroke with different contexts. Methods: Three patients with chronic stroke underwent physical therapy examination and intervention sessions via telerehabilitation with varying contexts. Results: Various factors affected the results of the assessment including patient and caregiver’s (if present) ability to follow instructions, availability of material and spatial resources, and stability of internet connection. Strategies to improve reliability of assessment results can also be employed such as performing repeat trials, reviewing recordings for accuracy and confirmation, using highly visible markers, and confirming measurement accuracy on video. Discussion: Physical therapy outcome measures that can feasibly be administered remotely are the Timed Up and Go Test, the 10-Meter Walk Test, the 6-Minute Walk Test, the 5-Times Sit to Stand Test, and the Stroke Impact Scale. The Mini Balance Evaluation Systems Test could not be administered remotely as close to standard protocol as possible due to the difficulty of administering the reactive postural component with patient anxiety and safety considerations and materials required.
