Initial Development and Psychometric Evidence of Physical Education Grit Scale (PE-Grit).

BackgroundGrit is a key concept in positive psychology and educational science. The construct measures two related constructs that are interest and effort. Several instruments have been developed to measure this construct in professional and educational contexts, but no tools have been developed considering specific contexts such as physical education and sport.ObjectivesThe objective of this study is to develop and test a measurement scale to assess Grit in the context of physical education and sport.MethodsTwo exploratory (Phase 1) and confirmatory (Phase 2) samples were administered the 16-item PE-Grit scale in Arabic. In addition, the confirmatory sample also was administered the R-SPQ-2F two-factor learning approaches scale. The factor structure was examined first by exploratory factor analysis on the first sample and then by confirmatory factor analysis on the second sample. Reliability testing was performed by checking internal consistency simultaneously by the three indices: McDonald's ω, Cronbach's α and Gutmann's λ6. Concurrent validity was checked by Pearson's correlation between the PE-Grit and the two dimensions of the SPQ-2F.ResultsAfter the exploratory factor analysis, which identified the factors and gave a preliminary validation of the designed instrument, confirmatory factor analysis was performed on three hierarchical models to be able to identify the best fitting model. A third-order hierarchical model with two physical and academic components each formed by interest and effort presented the best fit indices: chi X2 = 192.95 (p < 0.01), and the X2/DF = 1.36; GFI = 0.99; AGFI = 0.99; CFI and TLI close to 1; RMSEA = 0.025. In addition, McDonald's ω, internal consistency, and Gutmann's λ6 ranged from 0.78 to 0.86 for all four scale dimensions.ConclusionThe PE-Grit scale displays adequate factor structure, good reliability, and acceptable concurrent validity and can be administered to assess Grit in physical education and sport students.

Validation of a developmental screening checklist for Chinese preschoolers in Hong Kong

ABSTRACT There are concerns about the cultural validity of applying developmental screeners developed and normed in Western countries to other sociocultural contexts. Given the scarcity of culturally validated developmental checklists for use among Chinese children, the Hong Kong Society for the Protection of Children (HKSPC) has developed the HKSPC Developmental Checklist (HKSPC-DC) for preschool teachers to identify children at risk of developmental delays through daily observation of children’s functioning at school. This study explored the psychometric properties of the HKSPC-DC among 1183 preschool children aged 2–6 recruited from 14 nursery schools in Hong Kong. The HKSPC-DC showed excellent internal consistency, good interrater and test–retest reliabilities, and acceptable concurrent validity when correlated with the Taipei City Developmental Checklist for Preschoolers (Taipei II), which is the only screening instrument developed in a Chinese society and validated across 4- to 72-month-olds. The HKSPC-DC also showed good discriminatory power in identifying preschoolers potentially at risk of developmental delays. This screening tool may help facilitate early identification of children with developmental vulnerabilities in Chinese preschool populations.

Translation and validation of Chinese version of sense of competence in dementia care staff scale in healthcare providers: a cross-sectional study

BackgroundHealthcare providers’ dementia-care competence is crucial for quality dementia care. A reliable and valid instrument is needed to assess the gaps in their dementia-care competence, and thereby identifying their educational needs. Therefore, this study aims to translate the 17-item Sense of Competence in Dementia Care Staff (SCIDS) scale into Chinese (SCIDS-C) and to validate the SCIDS-C among Chinese healthcare providers.MethodsThe translation procedure followed the modified Brislin’s translation model. A cross-sectional survey was conducted using the translated version. The validity, including content validity, confirmatory factor analysis, concurrent validity and known-groups validity, was tested. Reliability in terms of internal consistency and test-retest reliability with a 2-week interval was evaluated.ResultsA total of 290 healthcare providers in 12 nursing homes and a hospital completed the survey. The scale-level content validity index was .99. The confirmatory factor analysis model marginally supported the original 4-factor structure. Positive but weak correlations were noted between the total score of the SCIDS-C and that of the Dementia Knowledge Assessment Scale (r = .17, p = .005) and Approaches to Dementia Questionnaire (r = .22, p < .001), suggesting acceptable concurrent validity. Differences between health professionals and care assistants were significant in two subscales scores. The internal consistency of the scale was high, with Cronbach’s α of .87. Test-retest reliability was demonstrated with intra-class correlation coefficient of 0.88.ConclusionsThe SCIDS-C demonstrated acceptable reliability and validity although the known-groups validity between health professionals and care assistants was not fully established. It can be used to measure the level of sense of competence and as an outcome measure in educational intervention aiming at improving dementia care among Chinese healthcare providers.

Validity of self-reports of medication treatment of depression in general population surveys.

To assess the concurrent validity of a single question on medication use for depression in a general population survey. Using data from 2015 to 2016 and 2017 to 2018 National Health and Nutrition Examination Survey, we compared responses to a single question on medication use for depression with responses to a detailed questionnaire confirmed by inspecting medication packages or pharmacy printouts. There was a strong agreement (96.4%) between response to a single question about using medication for depression and responses to questions about using antidepressants or other psychiatric medications for depression on the detailed questionnaire. The single-question assessment had excellent sensitivity (93.8%) and specificity (96.7%), positive predictive value (71.5%), and kappa (0.79). Psychometric properties were mostly consistent across population subgroups. Single-question assessments of medication use for depression have acceptable concurrent validity against more detailed assessments and provide an efficient method for assessing medication treatment of depression in population health surveys.

Structural robustness of life satisfaction scale of pre-service teachers in Nigeria

This paper investigated the structural robustness of the Life Satisfaction Scale (LSS) among Nigerian Pre-service Teachers. The study anchors on scale development research type of non-experimental design. Participants were selected randomly, totaling 509. The adopted instrument titled satisfaction with life scale with content validity index of 0.84 and ordinal alpha reliability of (α=0.75) aided in gathering data for the study. Obtained data were analysed using Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and concurrent validity (that is equating with Rosenberg Self Esteem scale), respectively. The results showed that a single trait was evident in the scale, with Eigenvalues of 2.41, 0.97, 0.64, 0.53, and 0.44. Also, the CFA indicated a good fit to the data with compliance indices. A significant positive correlation of the LSS with the Rosenberg self-esteem scale (r=0.83, P&lt;0.05) indicated acceptable concurrent validity. Similarly, LSS maintains its strict invariance regarding gender. The authors concluded that there was psychometric confirmation for a unitary structure of LSS in Nigeria, and since the two scales produced high correlations, the validity of LSS is referred to as concurrent. Therefore, it was recommended that LSS be used to complement scales that emphasise emotional well-being since it accesses an individual’s conscious evaluative judgment of his or her life using personal criteria.

Development and validation of the Professional Nursing Support Scale for Chinese patients with cancer.

This study aimed to develop and test the psychometric properties of a Professional Nursing Support Scale for patients with cancer in mainland China. The study was conducted in two phases from January 2017 to January 2020. Phase I involved item generation and developing a preliminary version of Professional Nursing Support Scale through literature review, qualitative interviews, content validity evaluation and a pilot study. Phase II involved psychometric properties testing of the Professional Nursing Support Scale in 700 patients with cancer recruited from four public hospitals in Anhui Province, China. A 49-item Professional Nursing Support Scale was finally developed. Exploratory factor analysis showed a four-factor structure of the 49-item Professional Nursing Support Scale, accounting for 56.95% of variance. Cronbach's α ranged from 0.91 to 0.94 for the four subscales. Confirmatory factor analysis further confirmed the best model fit of four-factor structure of the Professional Nursing Support Scale. The Professional Nursing Support Scale also showed an acceptable concurrent validity with Supportive Care Needs Scale short form 34 (r = 0.75, p < 0.001) and Psychological Distress Thermometer (r = 0.39, p < 0.001). The Professional Nursing Support Scale is a reliable and valid instrument to assess perceived needs of professional nursing support and support acquisition in relation to the care in Chinese patients with cancer.

Reliability and Validity of the Chinese Version of the Scale for Assessing the Stigma of Mental Illness in Nursing

Background: The prevalence of mental illness continues to increase in China, but research on stigma is still in its infancy, and there are even fewer studies on stigma among nurses. A comprehensive, effective and reliable tool is needed to assess stigma in nursing so that it can be reduced or eliminated to improve nursing quality. This study aimed to translate a 20-item scale for assessing the stigma of mental illness in nursing into Chinese and evaluate its reliability and validity.Methods: An improved Brislin translation model was used to translate the nursing mental illness stigma assessment scale into Chinese. Content and face validity were determined by a panel of experts. A convenience sample of 501 nursing students was chosen. Confirmatory factor analysis, concurrent validity and known group comparison were used to evaluate the scale's structural validity. The reliability was evaluated based on the internal consistency reliability and 2-week retest reliability.Results: The content validity index was 0.90. Confirmatory factor analysis showed that this study supported the three-factor model. The moderate correlation between the Chinese version of the Scale for Assessing the Stigma of Mental Illness in Nursing and the Perceived Devaluation Discrimination Scale suggested acceptable concurrent validity. Cronbach's α (0.863) and the retest coefficient (0.839) were indicative of internal consistency.Conclusion: The Chinese version of the Scale for Assessing the Stigma of Mental Illness in Nursing has acceptable concurrent validity, marginal factor validity, and satisfactory reliability in China. Therefore, the three-factor structure of the Chinese scale should be considered.Relevance to Clinical Practice: The Chinese version of the Scale for Assessing the Stigma of Mental Illness in Nursing can be used to understand the degree of mental illness stigma in nursing.

Validity of an early parent-report questionnaire for language disorder in very preterm children from 2 to 10 years of age.

Language problems at an early age in very preterm (VP) children can have a detrimental effect on other developmental domains and often persist throughout childhood. The aim of this study was to examine the concurrent and predictive validity of an early language parent-report questionnaire for language disorder in VP children from 2 to 10 years of age. In 80 VP children (<32 weeks' gestation) without major disabilities, a parent-questionnaire and formal language assessment, both normed for the general population, were administered at 2 years corrected age (CA). Of these infants, 62 were seen for follow-up formal language assessment at age 4 and 61 were seen at age 10. Sensitivity and specificity values were calculated. The Lexi-list showed acceptable concurrent validity for word production scores obtained at age 2 CA. The predictive validity was good for sentence production and acceptable for word production scores obtained at age 4, and low for language production scores obtained at age 10. A Lexi-list cut-off score of <85 (i.e., <-1 SD) was found optimal. A norm-referenced parent-report questionnaire is a useful, first screening tool in a neonatal follow-up. It not only detected early language disorder at age 2 CA but also proved to be a good predictor for language disorder at age 4. However, it did not predict language disorder at age 10. Formal language assessment at age 4 would therefore be recommended for children with an abnormal parent-report language score at age 2 CA.

Concurrent validity and responsiveness of Traffic Light System-BasicADL (TLS-BasicADL)

Purpose To test validity and responsiveness of Traffic Light System-BasicADL (TLS-BasicADL). Method Validity: Data according to TLS-BasicADL, modified Functional Independence Measure (FIM) and Barthel Index (BI) were collected from 50 patients with mixed medical diagnoses. Responsiveness: 106 patients following hip fracture assessed according to TLS-Basic ADL and modified Katz Index. Percentage change in TLS-BasicADL from pre-fracture status, to post-operatively, discharge and 1 month follow-up was calculated. TLS-BasicADL and modified Katz Index were also correlated at discharge and 1 month. For analysis of responsiveness, Spearman’s rho coefficient (rs) was used and for distribution at item level, percentage change and sign test. Results Validity: Strong-excellent correlations between TLS-BasicADL and modified FIM (0.65–0.95), TLS-BasicADL and modified BI (0.77–0.97) for individual items. Analysis of total scores revealed excellent correlations between instruments (0.96–0.98). Responsiveness: Significant differences between assessments for each item of TLS-BasicADL except upper hygiene, dressing and eating. Excellent correlation was found between TLS-BasicADL and modified Katz Index between pre-fracture – discharge (0.897) and moderate-strong (0.597) discharge − 1 month. Conclusion TLS-BasicADL is shown to have acceptable concurrent validity for measuring basic mobility and self-care in elderly patients with mixed medical diagnoses and responsive for patients following hip fracture surgery. Trial registration Investigation of responsiveness is registered in ClinicalTrials.gov Identifier: NCT03301584 (Retrospectively registered: 4th October 2017). KEYPHRASES Traffic Light System-BasicADL (TLS-BasicADL) provides a simple assessment scale that highlights level of independence in basic activities of daily living. TLS-BasicADL gives the multi/inter-disciplinary team a baseline showing the persons previous and present level of function and visual aid for discussing rehabilitation goals and need for future care. TLS-BasicADL is shown to have acceptable concurrent validity for measuring basic mobility and self-care in elderly patients with mixed medical diagnoses and responsive for patients following hip fracture surgery.

Craving for Ketamine and Its Relationship With Clinical Outcome Indicators in Males With Ketamine Use Disorder.

Background: Craving is considered a hallmark of substance use disorder and is one of the criteria of substance use disorder. The Desires for Drug Questionnaire (DDQ) is a widely used questionnaire to assess craving for heroin. This study aimed to examine the psychometric properties of the ketamine version of the DDQ (DDQ-K) and the associations between craving for ketamine as measured using the DDQ-K and clinical outcome indicators in individuals with ketamine use disorder.Methods: In total, 651 individuals with ketamine use disorder completed the DDQ-K and the Visual Analog Craving Scale (VACS). Demographic data, severity of ketamine use, money spent on ketamine, positive/negative aspects of ketamine use, and readiness to change ketamine use were also recorded. We examined the reliability (internal consistency), construct validity (factor structure), and concurrent validity of the DDQ-K. Multiple regression analysis was used to examine the relationships of craving measured using the DDQ-K with clinical outcome indicators, including money spent on ketamine, severity of ketamine use, positive/negative aspects of ketamine use, and readiness to change ketamine use.Results: The original three-factor model of the DDQ-K was acceptable for use in individuals with ketamine use disorder according to confirmatory factor analysis. The subscales of Desire and Intention and Negative Reinforcement of the DDQ-K, but not the subscale of Control, were of acceptable concurrent validity. The score on the Desire and Intention subscale was positively associated with the level of ketamine dependence, money spent on ketamine use, and positive/negative aspects of ketamine use and negatively associated with readiness to change ketamine use.Conclusion: This study supported the use of the Desire and Intention and Negative Reinforcement subscales of the DDQ-K to assess craving in patients with ketamine use.

Virtual OSCE Implementation for Remote Family Medicine Clinical Assessment During COVID19; Opportunities and Limitations

Abstract: Background: With the continuity of the COVD-19 pandemic and the rapid emergency remote teaching, Assessment was considered problematic. Objective structured clinical examination (OSCE) to assess the core skills required for the family physician is mandatory despite the circumstances. Objectives: This paper is to describe the experience of planning and conducting a virtual OSCE during the COVID-19 pandemic. Methods: Students enrolled in the professional family medicine diploma were the participants of the study. A suggested set-up of the virtual OSCE exam using the ZOOM meeting application was approved by the diploma council. Pilot Mock was done after orientation and preparation. Exam was conducted on parallel 2 sets of stations, each set is composed from 4 stations, facilitated by 3 coordinators and 1 assistant host in the ZOOM session. Each session included 10 students, 4 examiners. Coordinators (hosts) assigned assessors and role players in the designated (virtual) breakout rooms with the candidate, instructions displayed all through the station on the white board of this room. Results: Pilot Mock was conducted, and the feedback was improved in the actual exam setting. Nearly 18 examinee, 8 assessors and 3 moderators and administrate commenced the actual exam. Almost 87.5 % of the assessors were satisfied with the exam. The correlation of the virtual OSCE to written assessment was 0.52 which shows acceptable concurrent validity. Conclusion: Virtual OSCE is still an early version of a method for assessing the clinical skills remotely that needs logistics and further study.

Psychometric Properties of the Persian Version of the 11-Item de Jong Gierveld Loneliness Scale in Iranian Older Adults.

Loneliness is usually a chronic condition which may lead to physical and psychological undesirable consequences, and requires measurement and intervention. This study was conducted with the aim of preparing a Persian version of the 11-item de Jong Gierveld Loneliness Scale and evaluating its psychometric properties among the Iranian older adults. After applying the translation-back translation method, the prepared script was subjected to the face and content validity evaluations and a Persian version of the scale was prepared. Factor analysis, concurrent validity, internal consistency, and test-retest methods were used to validate the scale. The Persian version of the 11-item de Jong Gierveld Loneliness Scale showed acceptable content validity. The negative and significant correlations between the loneliness scores and the Philadelphia Geriatric Center Morale Scale indicated that the questionnaire had acceptable concurrent validity. The results of confirmatory factor analysis confirmed two factors for the scale. Also, the results of the intra-class correlation coefficient and Cronbach's alpha coefficient demonstrated that the scale had acceptable reliability. The Persian version of the 11-item de Jong Gierveld Loneliness Scale is an appropriate tool for measuring loneliness in the Iranian older adults.

The concurrent validity of the Abilitator: a self-assessment questionnaire on functioning and work ability

AimThe Abilitator is a self-assessment questionnaire which was developed to evaluate the perceived work ability and different aspects of functioning of working-age people. The present study aimed to explore the concurrent validity of the Abilitator.Subject and methodsThe participants (n = 177) were patients of a rehabilitation outpatient clinic. Their mean age was 47.1 years. Using Spearman’s correlation coefficients, we assessed the concurrent validity of the Abilitator to compare it to the HAD, RAND-36, EQ-5D, and WHODAS 2.0 (12-item short version) questionnaires.ResultsThe five domains of the Abilitator showed fair to moderate correlation coefficients with the previously validated and accepted measures of functioning. The strongest correlations were found in specific domains measuring similar constructs, namely social inclusion and RAND-36 vitality/fatigue (rs = 0.58), psychological functioning and RAND-36 emotional well-being (rs = 0.67) and HAD depression (rs = −0.65), everyday activities and total score of EQ-5D (rs = 0.63), cognitive functioning and WHODAS 2.0 cognition (rs = 0.57), and physical condition and RAND-36 physical functioning (rs = 0.70). Analysis by subpopulations of gender and age group showed a broadly similar pattern to that of the total sample. In general, stronger correlations were seen among women and among those of a younger age (50 years or under).ConclusionThe Abilitator questionnaire has acceptable concurrent validity for assessing different aspects of the functioning of working-age people.

Concurrent Validity and Reliability of the Transfer Assessment Instrument Questionnaire as a Self-Assessment Measure

ObjectivesTo evaluate the psychometric properties of the Transfer Assessment Instrument Questionnaire (TAI-Q), a self-assessment measure to evaluate transfer quality compared with clinician-reported measures. DesignParticipants self-assessed transfers from their wheelchair to a mat table using the TAI-Q. For session 1, participants self-assessed their transfer both before and after reviewing a video of themselves completing the transfer (session 1). Self-assessment was completed for another transfer after a 10-minute delay (session 2, intrarater reliability) and after a 1- to 2-day delay (session 3, test-retest reliability). Self-assessment was compared with a criterion standard of an experienced clinician scoring the same transfers with the Transfer Assessment Instrument (TAI) version 4.0 (concurrent validity). Setting2017 National Veterans Wheelchair Games. ParticipantsConvenience sample of full-time wheelchair users (N=44). InterventionsNot applicable. Main Outcome MeasuresTAI-Q and TAI. ResultsAfter video review of their transfer, acceptable levels of reliability were demonstrated for total TAI-Q score for intrarater (intraclass correlation [ICC], 0.627) and test-retest reliability (ICC, 0.705). Moderate to acceptable concurrent validity was demonstrated with the TAI (ICC, 0.554-0.740). Participants tended to underestimate the quality of their transfer (reported more deficient items) compared with the TAI. However, this deficit decreased and reliability improved from pre-video review to post-video review and from session 1 to session 2. The minimum detectable change indicated that a change of 1.63 to 2.21 in the TAI-Q total score is needed to detect a significant difference in transfer skills. ConclusionsWhen paired with video review, the TAI-Q demonstrates moderate to acceptable levels of reliability and validity for the total score. Self-assessment was completed quickly (<5min) and could help to potentially screen for deficiencies in transfer quality and opportunities for intervention.

Validation of a Chinese version of the dementia knowledge assessment scale in healthcare providers in China.

To translate 25-item Dementia Knowledge Assessment Scale into Chinese and evaluate its psychometric properties amongst Chinese healthcare providers. The prevalence of dementia is increasing in China, but development of relevant training for healthcare providers is still in its infancy stage. A comprehensive, valid and reliable Chinese knowledge-of-dementia measure is needed to identify training needs and evaluate the effect of educational interventions. A cross-sectional survey. The Dementia Knowledge Assessment Scale was translated into Chinese following the modified Brislin's translation model. Content and face validity were established by an expert panel in dementia care and healthcare providers. A convenience sample of 290 healthcare providers in care homes and hospitals was recruited. Construct validity was evaluated through confirmatory factor analysis, concurrent validity and known groups' comparisons method. Reliability was evaluated through internal consistency reliability and 2-week test-retest reliability. This study used the STROBE checklist for reporting. The content validity index was 0.98. The confirmatory factor analysis model revealed that the four-factor model was partly supported in the present study. The moderate correlation between Chinese version of Dementia Knowledge Assessment Scale and Alzheimer's Disease Knowledge Scale indicated acceptable concurrent validity. The mean score of the scale and subscale scores showed significant differences between health professionals and care assistants, except for the subscale of "Care Considerations." The reliability was demonstrated with Cronbach's alpha of .77 and intra-class correlation coefficients of each subscale between .74 and .92 among 56 respondents. The Chinese version of Dementia Knowledge Assessment Scale demonstrated acceptable concurrent validity but marginal factorial validity and satisfactory reliability amongst Chinese healthcare providers. Therefore, applying the four-factor structure of Chinese version scale should be considered. Chinese version of Dementia Knowledge Assessment Scale can be used to understand the training needs of healthcare providers in dementia.

Development of the English Listening and Reading Computerized Revised Token Test Into Cantonese: Validity, Reliability, and Sensitivity/Specificity in People With Aphasia and Healthy Controls.

Purpose This study reports the psychometric development of the Cantonese versions of the English Computerized Revised Token Test (CRTT) for persons with aphasia (PWAs) and healthy controls (HCs). Method The English CRTT was translated into standard Chinese for the Reading-Word Fade version (CRTT-R-WF-Cantonese) and into formal Cantonese for the Listening version (CRTT-L-Cantonese). Thirty-two adult native Cantonese PWAs and 42 HCs were tested on both versions of CRTT-Cantonese tests and on the Cantonese Aphasia Battery to measure the construct and concurrent validity of CRTT-Cantonese tests. The HCs were retested on both versions of the CRTT-Cantonese tests, whereas the PWAs were randomly assigned for retesting on either version to measure the test-retest reliability. Results A two-way, Group × Modality, repeated-measures analysis of variance revealed significantly lower scores for the PWA group than the HC group for both reading and listening. Other comparisons were not significant. A high and significant correlation was found between the CRTT-R-WF-Cantonese and the CRTT-L-Cantonese in PWAs, and 87% of the PWAs showed nonsignificantly different performance across the CRTT-Cantonese tests based on the Revised Standardized Difference Test. The CRTT-R-WF-Cantonese provided better aphasia diagnostic sensitivity (100%) and specificity (83.30%) values than the CRTT-L-Cantonese. Pearson correlation coefficients revealed significant moderate correlations between the Cantonese Aphasia Battery scores and the CRTT-Cantonese tests in PWAs, supporting adequate concurrent validity. Intraclass correlation coefficient showed high test-retest reliability (between .82 and .96, p < .001) for both CRTT-Cantonese tests for both groups. Conclusions Results support that the validly translated CRTT-R-WF-Cantonese and CRTT-L-Cantonese tests significantly differentiate the reading and listening comprehension of PWAs from HCs and provides acceptable concurrent validity and high test-retest reliability for both tests. Furthermore, favorable PWA versus HC sensitivity and specificity cutoff scores are presented for both CRTT-Cantonese listening and reading tests.

Examining the Structure of the PERMA Theory of Well-Being in Veterans With Mental Illnesses

Assessing and improving veterans’ well-being, especially those veterans who are at risk for or experiencing mental illnesses, has received national attention. We examined (a) the structural validity of the Positive emotion, Engagement, Relationships, Meaning, and Accomplishment (PERMA) theory of well-being and (b) psychometric properties of the PERMA-Profiler in veterans with mental illnesses. The sample consisted of one-hundred and fifty-six veterans with mental illnesses. Confirmatory factor analysis (CFA) and hierarchical CFA were conducted to test one-factor, five-factor, and a second-order PERMA model. Our findings indicated that re-specified second-order model was found to have best model fit indices. The subconstructs of the PERMA were correlated with resilience and functional limitations in theoretically expected direction. The PERMA-Profiler scale was found to have strong internal consistency and acceptable concurrent validity in a sample of veterans with mental illnesses. Rehabilitation counseling clinicians and researchers can use the PERMA-Profiler to screen the five pillars of well-being and overall well-being in veterans with mental illnesses through the lens of an empirical PERMA theory of well-being.

A Longitudinal Comparison of Patient-Reported Outcomes Measurement Information System to Legacy Scales in Knee and Shoulder Arthroscopy Patients

The purpose of this prospective correlational study was to compare the psychometric properties of the Defense and Veterans Pain Rating Scale (DVPRS) and Patient-Reported Outcomes Measurement Information System (PROMIS) scales with those of traditional legacy scales over a longitudinal postoperative period in patients undergoing arthroscopic procedures. Active-duty military personnel undergoing shoulder and knee arthroscopic procedures completed the DVPRS, PROMIS, and legacy scales preoperatively and again at 3 months postoperatively. Rolling correlation coefficients (rrm) were used to assess the concurrent validity between the DVPRS average pain scores and computer adaptive testing PROMIS scales (Anxiety, Depression, Pain Behavior, Pain Interference, Mobility, Sleep Disturbance, Satisfaction With Social Roles, and Upper Extremity Physical Function) and the legacy scales (American Shoulder and Elbow Surgeons [ASES] scale, Shoulder Activity Scale, International Knee Documentation Committee [IKDC] questionnaire, Single Assessment Numeric Evaluation [SANE], Marx Activity Rating Scale, and Veterans RAND 12-Item Health Survey). A total of 121 participants completed the scales preoperatively, 80 completed them at 3months postoperatively, and 59 (49% of participants) completed them at both times. Rolling correlation coefficients between PROMIS Pain Interference (rrm= -0.41, P= .006), Satisfaction With Social Roles (rrm= 0.56, P < .001), and Upper Extremity (rrm=0.71, P < .001) scores showed acceptable concurrent validity with ASES scores over a longitudinal postoperative period. DVPRS scores (rrm= -0.69, P= .002) and PROMIS Pain Behavior (rrm= -0.57, P= .018), Pain Interference (rrm= -0.71, P= .001), Sleep Disturbance (rrm= -0.64, P= .005), and Mobility (rrm= 0.65, P= .005) scores showed acceptable concurrent validity with IKDC scores. There was poor correlation between the PROMIS and DVPRS scores and the Single Assessment Numeric Evaluation, Marx Activity Rating Scale, Shoulder Activity Scale, and Veterans RAND 12-Item Health Survey scores. PROMIS scales measuring physical function, pain presentation, and other health domains showed acceptable concurrent validity with ASES and IKDC scores. By integrating the prospective collection of biopsychosocial PROMIS scales into practice, it is possible for clinicians in orthopaedic settings to assess changes in validated patient-reported outcomes to inform patient-centered care planning throughout the postoperative recovery period. Level II, prospective comparative study (with not all participants completing follow-up).

A Prospective Study for Prediction of Psychotic Relapse Using the Korean Early Signs Scale in Patients With Schizophrenia.

A psychotic relapse of schizophrenia is commonly preceded by nonpsychotic behavioral symptoms and signs, and detection of these early signs may enable prevention of relapse of schizophrenia. This study aimed to test the predictive validity of a Korean version of Early Signs Scale (K-ESS) for psychotic relapse for detecting the early signs. In this multicenter noninterventional 52-week prospective study, outpatients diagnosed as having schizophrenia within 5 years were recruited. The K-ESS and Clinical Global Impression-Severity (CGI-S) scale were administered monthly until the end of the study or the relapse. The primary objective was to determine an optimal cutoff point of K-ESS score for prediction of psychotic relapse. The secondary objective was to assess the concurrent validity of the K-ESS using CGI-S scale. Among the 162 included patients, 14 (8.6%) relapsed during the 52-week study period. The optimal cutoff score of K-ESS was 15 with a sensitivity of 71.43% and a specificity of 52.70%, indicating poor predictive accuracy of K-ESS. A lower cutoff K-ESS score of 3 and a higher cutoff score of 28 were found in the subgroups with milder (CGI-S = 1-2) and severer (CGI-S = 3-4) symptom severity, respectively, with fair to good predictive accuracy. The K-ESS showed acceptable concurrent validity with CGI-S and concordance rate between self-rated and informant-rated scores. The predictive accuracy of K-ESS was limited by evaluation interval of a month. At least fortnightly follow-up would be needed for detection of early signs to prevent a psychotic relapse in schizophrenia.

Clinical application of Chinese Nanjing persistent vegetative state scale

BackgroundIt is a challenge to characterize the consciousness level of patients with severe disturbance of consciousness and predict their prognosis effectively for Chinese doctors. We aimed to investigate the psychometric property and the diagnostic practicality of severe disturbance of consciousness by Chinese Nanjing persistent vegetative state scale (CNPVSS) which was first set up in 1996 and modified in 2001 and 2011.MethodsThe concurrent validity, inter-rater consistency and diagnostic accuracy of CNPVSS and Chinese version of coma recovery scale-revised (CRS-R) were investigated by assessment of 380 patients with severe disorders of consciousness.ResultsTotal scores of the CNPVSS were correlated significantly with that of the CRS-R, indicating acceptable concurrent validity. Sub-scale analysis showed moderate to high inter-rater reliability and test-retest reliability. CNPVSS was superior to CRS-R on the diagnosis sensitivity. The CNPVSS was able to distinguish 65 patients in emergence from minimal consciousness state who were misclassified as in minimal consciousness state (MCS) by the CRS-R, and it could also distinguish two patients in MCS who were misclassified as in vegetative state by the CRS-R.ConclusionThe CNPVSS is an appropriate measurement and is sensitive to distinguish the MCS patients from the VS patients.
