Clarifying and measuring the characteristics of experiences that involve a loss of self or a dissolution of its boundaries.

Mystical experience, non-dual awareness, selflessness, self-transcendent experience, and ego-dissolution have become increasingly prominent constructs in meditation and psychedelic research. However, these constructs and their measures tend to be highly overlapping, imprecise, and poorly integrated with similar pathological experiences. The present study seeks to clarify the common factors involved in the characteristics of these experiences using precise distinctions across an array of experience contexts (including meditation, psychedelics, and psychopathology). Participants (N = 386) completed an online survey about an experience that involved either a dissolution of self-boundaries or a loss of selfhood. Confirmatory factor analyses resulted in 16 experience characteristics, including multiple types of changes in sense of self, co-occurring phenomenology, and cognitive and affective responses. Qualitative thematic analysis provided rich descriptions of experience characteristics. Taken together, results lead to a more specific measurement model and descriptive account of experiences involving a loss of self or self-boundary.

Does a General "G Factor" Best Account for Hypnotizability?

The lead article in this issue of the International Journal of Clinical and Experimental Hypnosis (IJCEH), entitled, "Confirmatory Factor Analysis of the Elkins Hypnotizability Scale in a Clinical Population", reports on a factor analysis of hypnotizability scores in a clinical population of postmenopausal women. The results found evidence for a general hypnotizability latent variable. This finding suggests a general "G factor" may best account for hypnotizability. More research is needed, however, if confirmed in future research would lead to a new understanding of hypnotizability as having a single-factor structure. Existing research proposes greater recognition of the natural capacity of humans to intentionally alter their own experiences. Another study reports that perceptions of clinical hypnosis are positive among the public and healthcare providers, but more education of healthcare providers about hypnotherapy is needed. Additional articles are presented that examine the feasibility and potential benefit of clinical hypnosis in treatment of pain and distress among patients with fibromyalgia syndrome and in improving sleep disturbances in individuals with mild cognitive impairment.

Confirmatory Factor Analysis of the Elkins Hypnotizability Scale in a Clinical Population.

The objective of this study was to determine the best-fit factor structure of a standardized hypnotizability measure in a clinical population. The Elkins Hypnotizability Scale (EHS) was administered to 173 post-menopausal women, age from 39 to 75 years, with a mean age of 54.61 years. Confirmatory factor analysis was conducted, and comparative fit index (CFI) and root mean square error of approximation (RMSEA) were used to determine goodness of fit. Results indicated that the single-factor structure modeled with six indicators based on the individual items on the EHS provides the best description of fit. Results of the present study demonstrate that the EHS has a single-factor structure. Further research is required with other populations and measures.

Confirmatory Factor Analysis of the Spirituality and Spiritual Care Rating Scale: A Cross-Sectional Study in Eight US Nursing Homes.

The aim of this study was to test a modified Spirituality and Spiritual Care Rating Scale (SSCRS) and report initial findings, based on a cross-sectional descriptive survey from eight nursing homes in the USA. This study examined the psychometric properties of a modified version of the SSCRS for assessing the perceptions of staff (i.e. nurses, rehabilitation staff, food and nutrition service staff, activities staff, social workers, and administrative staff) who work in nursing homes. The modified version of the SSCRS is measuring respondents' perceptions of spirituality, spiritual care, religiosity, and personalized care. Confirmatory factor analysis showed satisfactory goodness of fit for the original four-factor structure of the SSCRS. The modified version demonstrated good internal consistency and reliability (Cronbach's alpha ranging from 0.71 to 0.90). Initial findings showed statistically significant differences across all four sub-scales. Further research is needed to psychometrically test the modified tool.

Development and initial validation of the trait and state Mindful Eating Behaviour Scales.

PURPOSE: The quantitative assessment of mindful eating has been challenging, even with the latest additions to the field of multifactorial mindful eating psychometric tools. This manuscript presents the development, validity and reliability assessment of a trait and state Mindful Eating Behaviour Scale across four studies driven by recent theory (Mantzios in Nutr Health 27: 1-5, 2021). METHODS: Study 1 assessed the content validity of the scale through ratings of clinical and research experts in the field. Study 2 inspected the scale through exploratory and confirmatory factor, parallel, correlation, and reliability analyses. Study 3 assessed the temporal stability through a test-retest in a 2-week interval. Study 4 assessed the scale in a randomized control experimental design, where a mindful eating (vs. control group) received the trait scale before consuming chocolate, and an equivalent state scale was modified to assess state changes during the 10-min eating session. RESULTS: Study 1 yielded items to be reflective and concise of the definition of mindful eating behaviour. Study 2 indicated 2 potential factors through exploratory factor analyses, which were further verified through a parallel analysis, while subscales correlation indicated one-dimensionality, which was further verified through confirmatory factor analysis. In addition, the internal consistency of the scale and subscales was good. Study 3 certified the reliability of the scale over time, while Study 4 indicated that both the trait and state scales were significant indicators of eating mindfully. CONCLUSIONS: Together, all studies signal the utility of theoretically sound and empirically validated measurements for the replicable assessment of mindful eating behaviour. LEVEL OF EVIDENCE: No level of evidence: basic science.

Safety voice climate: A psychometric evaluation and validation.

INTRODUCTION: Speaking up about safety issues, termed "safety voice," is a proactive response where people across all levels of the organization express their concerns to prevent physical hazards. An understanding of safety voice requires insight into its antecedents. A perceived need to fit in with the organization and fear of consequences can trump the courage to speak out about safety concerns. Safety voice climate can be seen as a manifestation of the social exchanges in an organization and functions as a roadmap of which speaking out behaviors are encouraged and which behaviors are not. This study conceptualizes safety voice climate, presents the Safety Voice Climate Scale (SVCS) as a measurement tool, and gathers initial evidence for its validity. The study also assesses the associations between the SVCS and safety voice behavior. METHOD: The SVCS and the measurement of safety voice behavior were derived from the Trends in Risk Level in the Norwegian Petroleum Activity questionnaire. The SVCS includes the two theoretical dimensions Work colleagues' encouragement of safety voice and Leaders' attitudes towards safety voice. Psychometric properties were tested with a representative sample from the Norwegian petroleum sector (n = 7,624). RESULTS: Confirmatory factor analyses supported the proposed two-factor model, and the internal consistency of the factors was good. Furthermore, a structural equation model including the SVCS as predictors of safety voice behavior showed a good fit, indicating acceptable criterion validity, although only the Work colleagues' encouragement of safety voice variable was significantly associated with safety voice behavior. Conclusion and practical application: The SVCS can be used as a tool to detect some of the barriers and supporting elements relating to safety voice and guidance on the efforts needed to foster work climates that promote communication of safety issues.

Patients' expectancy scale of acupuncture: Development and clinical performance test.

PURPOSE: This study aims to develop and validate a concise tool for evaluating acupuncture expectancy that is easy to understand and conforms to acupuncture characteristics. MATERIALS AND METHODS: A draft was created using the Delphi consensus method. Reliability, validity, discrimination, and feasibility tests were conducted at the item and scale levels. RESULTS: The scale themes were defined as disease-related, treatment-related, process-related, and outcome-related. After two rounds of Delphi surveys with good experts' reliability (authority coefficients of experts were 0.86 and 0.87 in the two rounds) and agreement (Kendall's concordance coefficient of the participants were 0.33 and 0.15 in the two rounds, P < 0.05), 11 items (the mean score for item importance, full mark ratios, and coefficient of variation of items were ≥3.5, ≥25%, and ≤0.30, respectively) were included in the draft. A total of 145 individuals were recruited to test the draft. Reliability was assessed by Cronbach's α coefficient (0.90), split-half reliability coefficient (0.89), and test-retest reliability (Pearson's coefficient = 0.74, P < 0.05). Content validity was assessed by the content validity index (Item-CVI ≥ 0.78 and Scale-CVI/Ave = 0.92), and a confirmatory factor analysis was performed to assess the construct validity. The discrimination of scale items was evaluated by the critical ratio (CR > 3.00) and the homogeneity test (item-total correlations >0.40). Feasibility was assessed through the acceptance rate (recovery rate = 98.60%, response rate = 100%), completion rate (100%), and completion time (4.99 ± 6.80 min). CONCLUSION: The patients' expectancy scale of acupuncture (PESA) consists of 11 items with four themes, disease-related, treatment-related, process-related, and outcome-related. It has great reliability, validity, discrimination, and feasibility and has the potential to evaluate acupuncture expectancy in clinical trials.

Development and testing of the Midwifery Perceptions and Assessment of Clinical Teaching (MidPaACT) tool.

OBJECTIVE: Develop and test a tool to measure midwives' perceptions of their role in preceptoring midwifery students. DESIGN: A multi method exploratory study design was used. POPULATION: Preceptor midwives from three maternity units in south-east Queensland Australia. METHODS: A three-phase process was used: item generation; expert review; psychometric testing including content analysis of qualitative responses. The survey was online or paper-based and included demographic details, the Clinical Preceptor Experience Evaluation Tool (CPEET) role subscale and draft tool. A focus group discussion explored the open-ended responses. FINDINGS: A large sample of preceptors (n = 164, 64.2 % response rate) participated. Factor analysis revealed a two-factor structure with 24 items accounting for 40.2 % of variance. The mean total score of the Midwifery Perceptions and Assessment of Clinical Teaching (MidPaACT) tool was 103.31 (SD = 9.47). The scale was reliable (Cronbach's alpha 0.89) and valid. Test-retest reliability showed moderate to excellent temporal stability across the scale and subscales. Measures of concurrent validity showed little agreement with the CPEET tool. Qualitative analysis revealed the way midwives were taught as students had a powerful influence on their approach to teaching in practice. CONCLUSION: This tool is specifically designed to assess midwifery preceptors' perceptions of their role in student learning in practice. Psychometric testing of the MidPaACT tool confirms its reliability and validity. IMPLICATIONS FOR PRACTICE: Midwifery preceptors are a key influence on the development of students' capability as a midwife. Midwives' perceptions of their proficiency in student learning are under-reported. The MidPaACT tool provides a reliable and valid means of measuring preceptors' perceptions and identifying areas for future educational and workforce improvement.

Psychometric testing of the nurse professional competence scale Arabic version: An exploratory and confirmatory factor analyses.

AIM: To translate the Nurse Professional Competence Scale-Short Form English version into Arabic and psychometrically validate its properties among Saudi citizen nurses. BACKGROUND: Evaluating nurses' professional competence is vital in delivering safe, cost-effective care and developing healthcare systems. However, psychometrically reliable and validated nurse competence scales in Arabic-speaking countries remain scant. DESIGN: A descriptive cross-sectional design adhering to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. METHODS: Participant nurses (n = 598) were conveniently recruited from four government-owned hospitals and completed the Arabic-translated 35-item Nurse Professional Competence Scale-Short Form. We used Spearman's rank-order correlation, exploratory factor analysis, Kaiser-Meyer-Olkin test, and confirmatory factor analysis to analyze the data. RESULTS: After exploratory factor analysis and reliability analyses, several items of the Arabic-translated 35-item Nurse Professional Competence Scale-Short Form were omitted due to high inter-item correlations and low factor loading difference. The Arabic version of the Nurse Professional Competence Scale-Short Form was reduced to 21 items, consisting of a three-factor structure: Professional Care Pedagogics, Holistic Value-Based Care, and Direct Nursing Care. Results also demonstrated that the revised three-factor structure had good overall scale reliability, good subscale internal consistencies, and acceptable construct validity using the confirmatory factor analysis. CONCLUSION: The 21-item Nurse Professional Competence Scale-Short Form Arabic version is a useful scale, having demonstrated construct validity and reliability. Therefore, nurse managers in Arabic-speaking nations could assess their nurses' professional competence using the 21-item Nurse Professional Competence Scale-Short Form Arabic version to develop proactive programs that enhance professional competence.

Adaptación transcultural al español rioplatense de la escala "Telemedicine Satisfaction and Usefulness Questionnaire" y evaluación del nivel de satisfacción global de la Tele-Rehabilitación en un Servicio de Kinesiología y Terapia Ocupacional / A Cross-cultural Adaptation of the "Telemedicine Satisfaction and Usefulness Questionnaire" Scale to Rioplatense Spanish and an Evaluation of the Global Satisfaction Level of Tele-Rehabilitation in a Kinesiology and Occupational Therapy Service

Introducción: el servicio de Kinesiología del Hospital Italiano de Buenos Aires adoptó la virtualidad para la atención de pacientes durante la pandemia de COVID-19. Se decidió realizar una adaptación transcultural del cuestionario de 17 ítems validado al español de España Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ) para conocer la satisfacción de los pacientes. Métodos: dos investigadores nativos realizaron una adaptación del cuestionario TSUQ al español rioplatense. Participaron pacientes atendidos entre mayo de 2021 y marzo de 2022 que habían realizado al menos cuatro sesiones de Tele-Rehabilitación (TR). Fue evaluada la correlación de la puntuación del instrumento resultante con la de un ítem agregado a modo de criterio externo concurrente. La validación del constructo fue llevada a cabo mediante sendos análisis factoriales exploratorios y confirmatorios. Resultados: obtuvimos 293 cuestionarios (media de edad 57 años, 64% sexo femenino). Luego de los resultados del AFE (Análisis factorial Exploratorio) (n = 101), consensuamos eliminar 5 ítems. El cuestionario resultante (12 ítems) fue luego validado en una nueva muestra (n = 192) a través de un AFC (Análisis factorial Confirmatorio). La fiabilidad compuesta, la varianza media extractada y la validez convergente fueron adecuadas, mientras que la validez discriminante fue escasa. Documentamos una moderada correlación (Spearman de 0,35, p < 0,0001) entre el puntaje total del cuestionario y el de la pregunta agregada como criterio externo concurrente de validación y una excelente correlación entre versiones. Conclusión: la versión abreviada del cuestionario TSUQ en español tiene propiedades psicométricas adecuadas, lo que lo vuelve un instrumento valioso para evaluar la satisfacción de los pacientes que realizan Tele-Rehabilitación.

Introduction: the Kinesiology service of the Hospital Italiano de Buenos Aires adopted virtuality for patient care during the COVID-19 pandemic. It was decided to make a cross-cultural adaptation of the 17-item Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ) validated for Peninsular Spanish to assess patient satisfaction. Methods: two native researchers adapted the TSUQ questionnaire to Riplatense Spanish. The participants were patients seen between May 2021 and March 2022 who had undergone at least four sessions of TR. We evaluated the correlation between the resulting instrument score and that of an item added as a concurrent external criterion. Construct validation was done with exploratory and confirmatory factor analysis. Results: we obtained 293 questionnaires (mean age 57 years, 64% female). After the AFE results (n=101), we agreed on eliminating five items. The final questionnaire (12 items) was tested in a new sample (n=192) with a CEA. Composite reliability, mean-variance extracted, and convergent validity were adequate, whereas the discriminant accuracy was low. We documented a moderate correlation (Spearman of 0.35, p < 0.0001) between the total questionnaire score and the aggregate question score as a concurrent external validation criterion and an excellent correlation between versions. Conclusion: the abbreviated version of the TSUQ questionnaire in Spanish has suitable psychometric properties, which makes it a valuable instrument for evaluating patient satisfaction in persons undergoing Tele-Rehabilitation.

A multiway spectral analysis model to monitor the kinetic chlorination reaction of caffeine and determine its content in commercial liquid and solid drinks.

A multiway data analysis model, namely parallel factor analysis (PARAFAC) was proposed to decompose a three-way array of second-order kinetic UV measurements, for the chlorination reaction of caffeine with NaOCl, into a set of the spectra, time, and concentration matrices. The multiway resolution provided the simultaneous estimation of spectral, kinetic, and quantitative analysis of caffeine. The ability of the PARAFAC tool was checked by analyzing the validation samples in the presence of interferences. The added recovery and relative standard deviations for caffeine in the spiked samples were calculated as 99.1%-99.5% and 0.52%-1.34% for Iced Coffee Black liquid coffee (ICB), 99.5%-103.0% and 0.42%-1.03% for Jacobs Monarch Gold 100% Instant Coffee (JMG) and 99.5%-101.4% and 0.11%-0.13% for Çaykur Black Filter (Süzen) Bag Tea (BTB). Caffeine in commercial drinks was analyzed using the concentration matrices of the PARAFAC application. The PARAFAC results were statistically compared to those obtained by the developed UPLC method.

Characteristics associated with subjective and objective measures of treatment success in women undergoing percutaneous tibial nerve stimulation vs sham for accidental bowel leakage.

INTRODUCTION AND HYPOTHESIS: In randomized trials both percutaneous tibial nerve stimulation (PTNS) and sham result in clinically significant improvements in accidental bowel leakage (ABL). We aimed to identify subgroups who may preferentially benefit from PTNS in women enrolled in a multicenter randomized trial. METHODS: This planned secondary analysis explored factors associated with success for PTNS vs sham using various definitions: treatment responder using three cutoff points for St. Mark's score (≥3-, ≥4-, and ≥5-point reduction); Patient Global Impression of Improvement (PGI-I) of ≥ much better; and ≥50% reduction in fecal incontinence episodes (FIEs). Backward logistic regression models were generated using elements with significance of p<0.2 for each definition and interaction terms assessed differential effects of PTNS vs sham. RESULTS: Of 166 women randomized, 160 provided data for at least one success definition. Overall, success rates were 65% (102 out of 158), 57% (90 out of 158), and 46% (73 out of 158) for ≥3-, ≥4-, and ≥5-point St Mark's reduction respectively; 43% (68 out of 157) for PGI-I; and 48% (70 out of 145) for ≥50% FIEs. Of those providing data for all definitions of success, 77% (109 out of 142) met one success criterion, 43% (61 out of 142) two, and 29% (41 out of 142) all three success criteria. No reliable or consistent factors were associated with improved outcomes with PTNS over sham regardless of definition. CONCLUSIONS: Despite exploring diverse success outcomes, no subgroups of women with ABL differentially responded to PTNS over sham. Success results varied widely across subjective and objective definitions. Further investigation of ABL treatment success definitions that consistently and accurately capture patient symptom burden and improvement are needed.

Screening of anti-fatigue active ingredients of Eleutherococcus senticosus via spectrum-effect relationship based on factor analysis and LC-MS/MS.

ES contains compounds known to have significant anti-fatigue activity. In recent years, it has received extensive attention because it is efficient. However, its active ingredients on antifatigue effect are still unclear. This study attempts to establish the spectrum-effect relationship of ES antifatigue activity to screen the effective components. The results showed that the similarity of 15 ES fingerprints obtained by LC-MS/MS was 0.533-0.992, and the chemical structures of 22 common peaks were identified. The anti-fatigue activity of 15 batches of ES was characterized by forced swimming test of mice and quantified by CAFI, among which S4, S1 and S5 had better activity. 9 components (caffeic acid, 5-(4-O-ß-D-glucosylferoyl)-quinic acid, (±)13-HODE, isofraxidin, eleutheroside E, syringin, pinoresinol diglucoside or its isomer, 7,8-dihydrodehydrocarbinol alcohol-4-O-ß-D-glucoside, secoisolariciresinol-4-O-ß-D-glucoside) highly related to anti-fatigue activity may be the effective components of ES.

Self-Compassion in Chinese Young Adults: Its Measurement and Measurement Construct.

OBJECTIVES: Self-compassion is the ability to be kind to oneself in adversity. This multidimensional construct is typically assessed by the Self-Compassion Scale (SCS). In Chinese samples, there have been inconsistent psychometric findings that impede cross-cultural research. This study aimed to explore the factor structure of the Chinese version (SCS-C). METHODS: Two samples of young Chinese adults were recruited (Sample 1, N = 465, 141 men, Mean age [Mage] = 20.26; Sample 2, N = 392, 71 men; Mage = 18.97). Confirmatory factor analyses and exploratory structural equation modeling (ESEM) were used to examine previously reported four- and six-factor structures of SCS-C. RESULTS: Although ESEM supported the six-factor structure when a problematic item was omitted, we found stronger evidence for a novel four-factor structure of the SCS-C revealed with self-kindness, common humanity, mindfulness, and uncompassionate self-responding. This suggests that Chinese individuals have a different understanding of the negative components of the original self-compassion definition, which was based on the United States and other mostly Western samples. Omega coefficients of the bifactor models suggested that using the SCS total score in Chinese samples is inappropriate. However, high factor determinacy and construct replicability indicated that the general factor of SCS-C could be used in a structural equation modeling context for both four-factor and six-factor structures. CONCLUSIONS: When using the existing SCS-C in path models, researchers should use a latent variable approach and establish the measurement construct rather than sum scores of the scale or subscales without checking the factor structure in future empirical studies. Also, the SCS-C needs to be revised, and we proposed directions forward for future research.

Spirituality and Spiritual Care in Nursing: Validity of the Spirituality and Spiritual Care Rating Scale in an Indian Context.

This study was undertaken to test the validity of the Spirituality and Spiritual Care Rating Scale (SSCRS) by McSherry et al. (IJNS 39:723-734, 2002) in an Indian context. The study was conducted in a tertiary care teaching hospital with a convenience sample of 200 nurses. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were completed to assess the reliability and validity of the tool. The results of the present study were similar to but differed from the McSherry et al's (IJNS 39:723-734, 2002) study which identified 17 items on the scale. Only 15 items loaded on three factors.

The FACIT-Sp spiritual wellbeing scale: a factor analysis in patients with severe and/or life-limiting medical illnesses.

BACKGROUND: The Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp) is a widely used measure of spiritual wellbeing. However, consensus on the best factor structure for this measure has not been reached. Both a 2-factor (Meaning/Peace, Faith) and a 3-factor (Meaning, Peace, Faith) structure are reported in the literature. In this study, we examined the factorial structure of the FACIT-Sp in a population of patients with severe and/or life-limiting medical illnesses. METHODS: The present study is a part of a larger study that validated the National Institute of Health-Healing Experiences of All Life Stressors (NIH-HEALS), a measure of psycho-social-spiritual healing developed by the Pain and Palliative Care Service at the National Institutes of Health Clinical Center (NIH-CC). The sample included 200 subjects who were recruited from the NIH Clinical Center inpatient units and outpatient clinics with severe and/or life limiting illnesses (cancer, non-genetic conditions, genetic conditions, blood dyscrasias). FACIT-Sp is a 12-item questionnaire scored on a 5-point Likert scale (0 = not at all; 4 = very much). Exploratory factor analysis (EFA) and principal component analysis (PCA) were used to analyze results and to identify the number of latent constructs and underlying factor structure. RESULTS: The results supported the 3-factor (Meaning, Peace, and Faith) model of the FACIT-Sp and accounted for the most variability (74.20%), followed by the 2-factor solution (64.95%). The identified factors related to Faith, Peace, and Meaning and were consistent with previously reported 3-factor model. CONCLUSIONS: This study confirmed the 3-factor structure of FACIT-Sp. This information can inform interventions aimed at improving quality of life and spiritual wellbeing in clinical and palliative care settings.

Trend changes and factor analysis of endometrial hyperplasia in patients with polycystic ovarian syndrome based on the Korean National Health Insurance Database.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with an increased risk of other gynecological disorders, such as endometrial hyperplasia (EH). However, substantial factors in the comorbidity of EH and PCOS remain to be investigated. We analyzed trend changes in PCOS and factors related to the comorbidity of PCOS and EH using data from the Korea National Health Insurance (KNHI) claims database. METHODS: The data for this population-based study of people diagnosed with PCOS or EH in Korea from 2009 to 2016 were collected from the KNHI claims database between 2007 and 2017. We conducted a trend analysis of the prevalence and incidence of PCOS and EH. In addition, we performed a logistic regression analysis to identify risk factors associated with EH incidence in people with PCOS using the matched case-control methodology. RESULTS: The average annual growth rate of the incidence of PCOS was 14.1% from 2009 to 2016, whereas the EH rate increased by only 3.4% annually. Comorbidities, type 2 diabetes, obesity, hypertension, hyperlipidemia, and infertility, increased the risk of EH in PCOS patients. Additionally, the cumulative duration of oral contraceptive & progestin treatment for PCOS correlated highly with the comorbidity of EH and PCOS. CONCLUSIONS: We confirmed the relationship between PCOS and EH using big data suitable for time series analyses of the diagnosis and treatment of diseases. Endometrial evaluation should be done with more caution if oral contraceptives & progestins have been used for a long time.

Numerical investigation on functional limitations of the anti-stall fin for an axial fan: one-factor analyses.

The stall in an axial fan is directly related to detrimental phenomena such as performance degradation, vibration, noise, and flow instability at low flow rates. As a kind of passive control method to handle the stall, two-dimensional plates so-named anti-stall fin (ASF) were suggested by ourselves and were attached inside the casing. In this study, the ASF's effect on the internal flow pattern was visually investigated in the flow passage, and its tendency was discussed with the performance curve. Subsequently, the ASF's functional limitations for various design parameters, which the ASF can derive aerodynamically, were presented as the primary focus of this study. Each one-factor analysis was performed, and the internal flow pattern was observed in parallel at the point where the ASF lost its function. For the radial length, axial length, number of fins, and positive-tangential angle, the ASF almost retained its function up to the limitation to prevent instability but radically lost its function at a certain flow rate. For the axial gap and negative-tangential angle, the ASF gradually lost its function. Mostly, this study was based on numerical analysis, and the performance was validated through experimental tests.

Development of the motivational thought frequency scale for alcohol abstinence (MTF-A).

BACKGROUND AND AIMS: For most treatment-seeking patients with severe Alcohol Use Disorder (AUD), abstinence is the clinically indicated goal. Existing AUD motivation scales are non-specific about treatment consumption goals, which limit their effectiveness. Desires and mental imagery are relevant in the motivation for AUD treatment engagement. The Motivational Thought Frequency Scale for an abstinence goal (MTF-A) was adapted from the MTF for controlled drinking (MTF-CD). This study psychometrically evaluated the MTF-A in an alcohol-dependent sample engaged in treatment with a goal of abstinence. To enhance the clinical utility of the scale, a secondary aim was to evaluate a psychometrically equivalent short version of the MTF-A. METHOD: A sample N of 329 treatment-seeking patients with AUD (mean age of 44.44 years, SD = 11.89 years, 72% male) who were undertaking a cognitive behavioral treatment (CBT) program for abstinence completed the Motivational Thought Frequency Scale for Abstinence (MTF-A) and the Severity of Alcohol Dependence Questionnaire (SADQ). The MTF-A measured motivation for abstinence through four factors: intensity, self-efficacy imagery, incentives imagery, and availability. Confirmatory factor analyses (CFAs) were conducted to examine factor structure and model fit. Cronbach's alpha assessed internal consistency. Predictive validity was determined by logistic regression predicting first-session treatment non-attendance and alcohol consumption between baseline assessment and commencement of treatment, controlling for potential confounds. RESULTS: A four-factor structure provided the best fit for the MTF-A, compared with one- and three-factor models. A shortened 9-item MTF-A scale (S-MTF-A) provided better fit than the 13-item MTF-A scale. Both MTF-A and S-MTF-A displayed good internal consistency. Although both MTF-A and S-MTF-A successfully predicted first-session treatment non-attendance, neither predicted alcohol consumption between the baseline assessment and commencement of treatment. CONCLUSIONS: The model fit of the four-factor, 9-item S-MTF-A was superior to the original 13-item MTF-A. Both scales were predictive of participation of AUD treatment. Desires and mental imagery play an important role in AUD treatment motivation.

Athletic trainers' viewpoints of patient-centered care: Preliminary findings.

The core competency of patient-centered care (PCC) states that for positive patient outcomes, the provider must respect the patient's views and recognize their experiences. The Athletic Training Strategic Alliance Research Agenda Task Force identified a profession-wide belief that examining the extent to which athletic trainers (ATs) provide PCC in their clinical practice would benefit the profession. To first address this line of inquiry, we must study the subjectivity of how ATs view PCC. This study used Q methodology which is a research design that collects data from participants from a quantitative and qualitative perspective. A total of 115 (males = 62, females = 53, age = 37±10 y, experience = 13±10 y) ATs dispersed between 11 job settings volunteered for this study. Participants were asked to pre-sort (agree, disagree, neutral) 36 validated statements representing the 8 dimensions of PCC, then completed a Q-sort where they dragged-and-dropped the pre-sorted statements based on perceived importance in providing PCC. The Q-sorts were analyzed using QMethod software. A principal component analysis was used to identify statement rankings and factors. Factors were determined by an Eigenvalue > 1 and analyzed using a scree plot. The 6 highest selected statements per factor were assessed to create the distinguishing viewpoints. Two distinguishing viewpoints emerged from the factor analysis of the Q-sorts: 1) the interpersonal connection that valued teamwork, open communication, and respectful care with varied populations; 2) the holistic gatekeeper that valued personal promotion for activities of daily living, self-care, and quality of life. Overall, ATs value patient's preferences and respect. However, a lack of importance was identified for incorporating the disablement model which is a core competency and adopted framework by the athletic training profession.
