Measuring the work environment among healthcare professionals: Validation of the Dutch version of the Culture of Care Barometer.

A positive work environment (WE) is paramount for healthcare employees to provide good quality care. To stimulate a positive work environment, employees' perceptions of the work environment need to be assessed. This study aimed to assess the reliability and validity of the Dutch version of the Culture of Care Barometer (CoCB-NL) survey in hospitals. This longitudinal validation study explored content validity, structural validity, internal consistency, hypothesis testing for construct validity, and responsiveness. The study was conducted at seven departments in two Dutch university hospitals. The departments were included based on their managers' motivation to better understand their employees' perception of their WE. All employees of participating departments were invited to complete the survey (n = 1,730). The response rate was 63.2%. The content of the CoCB-NL was considered relevant and accessible by the respondents. Two factor models were found. First, confirmative factor analysis of the original four-factor structure showed an acceptable fit (X2 2006.49; df 399; p = <0.001; comparative fit index [CFI] 0.82; Tucker-Lewis index [TLI] 0.80; root mean square error of approximation [RMSEA] 0.09). Second, explanatory factor analysis revealed a five-factor model including 'organizational support', 'leadership', 'collegiality and teamwork', 'relationship with manager', and 'employee influence and development'. This model was confirmed and showed a better fit (X2 1552.93; df 395; p = < 0.00; CFI 0.87; TLI 0.86; RMSEA 0.07). Twelve out of eighteen hypotheses were confirmed. Responsiveness was assumed between the measurements. The CoCB-NL is a valid and reliable instrument for identifying areas needing improvement in the WE. Furthermore, the CoCB-NL appears to be responsive and therefore useful for longitudinal evaluations of healthcare employees' work environments.

Development and validation of the adolescent behavioural change Counselling Assessment Tool in Indonesia

BackgroundPrimary care provides an important context to engage adolescents and their families in healthy lifestyles with the goal of reducing future behaviour-related health problems. Developing a valid tool to assess health professionals’ skills in behavioural change counselling is integral to improving the quality of clinical care provided to adolescents in Indonesia.MethodsThis work was nested within a project to develop a training program to enhance the behaviour-change counselling of adolescents and their parents by Indonesian primary care professionals. Initial item development was based on the content of the training module and the domain structure of the Behavioral Change Counselling Index (BECCI), a commonly used tool to assess counselling quality in healthcare settings. Expert panels were used to test content validity, while face validity was assessed by a group of trained psychologists. Inter-rater agreement was calculated prior to tests of construct validity and reliability, which involved psychologists rating 125 audio-taped counselling sessions between the health professional and adolescent patients, together with a parent.ResultsAn initial 13-item tool was developed using a 1–5 Likert scale. Validity and reliability testing resulted in the decision to use a 14-item tool with a 0–3 Likert scale. The scale was found to have a Cronbach’s α coefficient of 0.839 (internal consistency), and there was strong inter-rater agreement (0.931).ConclusionThe assessment tool known as the Adolescent Behavioural Change Counselling Assessment Tool, is a valid and reliable instrument to measure Indonesian health professionals’ behavioural-change counselling skills with adolescent patients. The tool provides an evaluation framework for future interventions that aim to improve health professionals’ skills in addressing adolescent behaviour-related health problems.

Rodent tests of depression and anxiety: Construct validity and translational relevance

Behavioral testing constitutes the primary method to measure the emotional states of nonhuman animals in preclinical research. Emerging as the characteristic tool of the behaviorist school of psychology, behavioral testing of animals, particularly rodents, is employed to understand the complex cognitive and affective symptoms of neuropsychiatric disorders. Following the symptom-based diagnosis model of the DSM, rodent models and tests of depression and anxiety focus on behavioral patterns that resemble the superficial symptoms of these disorders. While these practices provided researchers with a platform to screen novel antidepressant and anxiolytic drug candidates, their construct validity—involving relevant underlying mechanisms—has been questioned. In this review, we present the laboratory procedures used to assess depressive- and anxiety-like behaviors in rats and mice. These include constructs that rely on stress-triggered responses, such as behavioral despair, and those that emerge with nonaversive training, such as cognitive bias. We describe the specific behavioral tests that are used to assess these constructs and discuss the criticisms on their theoretical background. We review specific concerns about the construct validity and translational relevance of individual behavioral tests, outline the limitations of the traditional, symptom-based interpretation, and introduce novel, ethologically relevant frameworks that emphasize simple behavioral patterns. Finally, we explore behavioral monitoring and morphological analysis methods that can be integrated into behavioral testing and discuss how they can enhance the construct validity of these tests.

Challenges of Measuring Self-Reported Exposure to Occupational Biomechanical Risk Factors Amongst People with Low Literacy Engaged in Manual Labour: Findings from a Cross-Cultural Adaptation and Psychometric Investigation in an African Population with Chronic Low Back Pain.

Occupational biomechanical factors are implicated in the aetiology and progression of low back pain (LBP). This study cross-culturally adapted and psychometrically investigated the Occupational Risk Factor Questionnaire (ORFQ) in a low literate Nigerian Igbo population with chronic LBP. Forward and back translation of the original ORFQ by clinical and non-clinical translators was followed by an expert committee review. The adapted ORFQ was pre-tested amongst rural Nigerian adults with chronic LBP using cognitive think-aloud interviewing. Internal consistency (Cronbach's alpha) and test-retest reliability (unweighted and linear weighted k statistic for item-by-item agreement, and intra-class correlation coefficient-ICC) were investigated amongst 50 rural and urban Nigerian dwellers with chronic LBP. Spearman's correlation and regression analyses were conducted with the Igbo-ORFQ, and measures of disability [World Health Organisation Disability Assessment Schedule (WHODAS 2.0), Roland Morris Disability Questionnaire (RMDQ), Back performance scale (BPS)], pain intensity [Eleven-point box scale (BS-11)] and social support [Multidimensional Scale of Perceived Social Support (MSPSS)], to test construct validity with 200 rural Nigerian dwellers with chronic LBP. Cross-cultural adaptation highlighted difficulty conceptualising and concretising exposure to biomechanical risk factors. Item-by-item agreement, internal consistency (α = 0.84) and intraclass correlation coefficient (ICC = 0.83) were good. Some unexpected direction of associations between the biomechanical components of the Igbo-ORFQ, and disability, pain intensity, and social support prohibits establishment of construct validity. Prospective studies comparing the Igbo-ORFQ to other measures of exposure to occupational biomechanical risk factors are required to establish the construct validity of the Igbo-ORFQ.

Validity and Reliability of Farra Eye Model as a Surgical Simulator for Capsulorhexis Training

Abstract&#x0D; Introduction &amp; Objectives : Various simulation models are available for cataract surgery training. Farra Eye Model, a new cataract surgery simulator, was developed to provide the resident with more affordable options. This study aims to determine the validity and reliability of the Farra Eye Model as a surgical simulator for capsulorhexis training.&#x0D; Methods : A cross-sectional pilot study was performed among ophthalmology residents and consultants to assess face, content, and construct validity of a new surgical simulator. Subjects were divided into novice, intermediate, and expert groups according to their level of expertise. Face and content validity was assessed using a validated questionnaire with a 5-point Likert scale response. Construct validity was done by comparing capsulorhexis performance between the three groups. Two raters assessed performance using capsulorhexis indices in ICO-OSCAR: Phaco assessment tool, number of forceps grabs, and duration of capsulorhexis.&#x0D; Results : A total of 33 subjects were recruited and divided equally into three groups. The overall face validity score was favorable (3.67 ± 0.67). However, the capsule elasticity was rated poor (2.73 ± 1.1) among the intermediate group. The content validity was favorable regarding the overall score (4.15± 0.58) and each assessment component. In the construct validity test, intermediate and expert groups showed better capsulorhexis performance than the novice group on all parameters (p&lt;0.001), with good inter-rater reliability (ICC&gt;0.7).&#x0D; Conclusion : Farra Eye Model has a good face and content validity for capsulorhexis training and is able to differentiate the novice group from intermediate and expert groups. However, it remains a challenge to replicate human lens capsule elasticity.

Validity of PBEST Learning Model: An Innovative Learning to Improve Creative Thinking Skill and Entrepreneurial Science Thinking

Based on the results of previous studies, evidence was acquired indicating that the creative thinking abilities of pupils in various locations of Indonesia still require improvement. Creative and innovative thinking in science learning integrated with entrepreneurship produces entrepreneurial science thinking. Learning interventions are needed to develop competitive graduates who can face challenges and rapid changes in the 21st century. This research aims to validate the Project Based Entrepreneurial Science Thinking (PBEST) learning model. The educational development research design used is the validation studies design, which tests two criteria, namely testing content validity (which is also called relevance) and construct validity (which is also called consistency). This validation involves three experts in science education, and the validation instrument uses a validation sheet. The research and data analysis indicate that the PBEST learning model consistently produces highly relevant results that meet rigorous validity and reliability standards (with a percentage of agreement ≥ 75%). The PBEST learning model consists of four stages, namely: (1) Observe and thinking project, (2) Design project, (3) Monitoring and evaluation project, (4) Economic value. The validation of the implementation supporting learning tools confirms the validity and reliability of the semester learning plans, lecture program units, student worksheets, student books, creative thinking skill tests, and entrepreneurial science thinking tests. The PBEST learning paradigm is applicable for enhancing both creative thinking skills and entrepreneurial science thinking.

Construct Validity Testing of the Provider Co-Management Index to Measure Shared Care in Provider Dyads.

Co-management encompasses the dyadic process between two healthcare providers. The Provider Co-Management Index (PCMI) was initially developed as a 20-item instrument across three theory-informed subscales. This study aimed to establish construct validity of the PCMI with a sample of primary care providers through exploratory and confirmatory factor analyses. We conducted a cross-sectional survey of primary care physicians, nurse practitioners, and physician assistants randomly selected from the IQVIA database across New York State. Mail surveys were used to acquire a minimum of 300 responses for split sample factor analyses. The first subsample (derivation sample) was used to explore factorial structure by conducting an exploratory factor analysis. A second (validation) sample was used to confirm the emerged factorial structure using confirmatory factor analysis. We performed iterative analysis and calculated good fit indices to determine the best-fit model. There were 333 responses included in the analysis. Cronbach's alpha was high for a three-item per dimension scale within a one-factor model. The instrument was named PCMI-9 to indicate the shorter version length. This study established the construct validity of an instrument that scales the co-management of patients by two providers. The final instrument includes nine items on a single factor using a 4-point, Likert-type scale. Additional research is needed to establish discriminant validity.

Understanding the Influence of Brand Experience and Brand Satisfaction on Brand Loyalty: Mediated by Brand Love

The aim of this research is to uncover the impact of brand experience and brand satisfaction on brand loyalty, with brand love mediating between the two. The research employs a deductive quantitative approach. The researcher utilizes a survey design with a sample size of 230 UMS students. Non-probability purposive sampling technique is chosen to select respondents for this study. Instrument testing is conducted through construct validity and reliability tests, which indicate valid and reliable results. Hypothesis testing is performed using SEM-PLS with the Smart PLS tool through outer and inner models. This study empirically demonstrates that brand love can mediate the influence of brand experience and brand satisfaction on brand loyalty. The theoretical contribution of this study offers insights into brand loyalty concerning brand experience, brand satisfaction, and brand love. The practical contribution suggests that companies should focus on brand satisfaction in addition to brand experience and brand love to contribute to the enhancement of brand loyalty.

An intervention to improve antibiotic prescription behavior in veterinary students: A protocol based on the multi-theory model to tackle antimicrobial resistance.

Antimicrobial resistance (AMR) is a global health threat. Moreover, incorrect and inappropriate drug prescription behavior is considered a fundamental risk factor. Thus, the present study aims to develop, implement, and evaluate the effectiveness of an educational program based on the multi-theoretical model (MTM) in improving antibiotic prescription behavior in veterinary students of Iran. The present study will include four phases including a qualitative phase, an instrument design and psychometric test phase, and a cross-sectional, and an interventional phase. In the first phase, the sampling will be purposive with a maximum variety. The interviews will be conducted with a sample of veterinarians. The data will be analyzed in MAXQDA 10. In the second phase, the face and content validity will be tested by a panel of experts as field specialists. A confirmatory factor analysis will be used to test construct validity, and Cronbach's alpha coefficient and intracluster correlation coefficient will be used to determine the internal consistency of the instrument. Then, at this stage, a number of veterinary students will be selected through a multi-stage sampling method. In the cross-sectional phase, another sample of veterinary students will complete a researcher-made questionnaire. Then, Spearman's correlation coefficient test will be used to test the relationship between the two stages of behavior initiation and behavior continuation. The data will be analyzed in SPSS 22. In the third phase, some veterinary students will be selected through a census and will be randomly divided into a control and an intervention group. To collect data in the final phase, the researcher-made questionnaire that was designed in the second phase of the study based on a multi-theory model will be used to extract data. To compare demographic characteristics, compare the correlation between the constructs of the multi-theory model with antibiotic prescribing behavior in the cross-sectional phase and compare the scores of the constructs of the MTM in two intervention and control groups paired-samples T test and independent-samples T test will be used. The present study will aim to improve antibiotic prescription behavior in veterinary students based on a MTM. The findings can be used as a model for training students in clinical fields such as veterinary medicine and general medicine at university at a national level. After verification and approval by experts and university professors, we can expect a change in the educational curriculum to include instructions on how to write out prescriptions for students. There are hopes that the present study if conducted accurately and widely to help prevent AMR in livestock, humans, and society.

Sexual function index adaptation for breast cancer patients (FSFI-BC)- translation and psychometric properties of Persian version

BackgroundEffective interventions to improve sexual dysfunction in breast cancer survivors need screening of these dysfunctions with a suitable instrument. The aim of present study was translation and identifying psychometric properties of Female Sexual Function Index – Adapted for Breast Cancer (FSFI-BC) which has been specifically developed for breast cancer survivors.MethodThis methodological study was performed between February 2017 and October 2018. 200 breast cancer survivors in stage 1 or 2 who were selected through convenience sampling method, completed the questionnaire. Reliability was assessed by Cronbach’s alfa and test re-test analysis and construct validity was performed through confirmatory (CFA) and exploratory factor analysis( EFA).ResultsSix factors were extracted in exploratory factor analysis (EFA). These factors explained 74.6% of the total variance in in NSA group and 0.821 in SA group. Reliability evaluation indicated high internal consistency and good test re-test reliability. Cronbach’s alpha coefficient in all areas of the tool was above 0.7 (the lowest and the highest measures were 0.885 and 0.945, respectively), which is a good indicator for reliability of an instrument. Confirmatory factor analysis showed an acceptable fitness for seven factors of FSFI-BC questionnaire (Normed Fit Index or NFI = 0.9 for both groups, Comparative of Fit Index or CFI = 0.93 and 0.92, χ 2/df = 1.68 and 1.71 for SA(Sexually Active) and NSA(No Sexually Active) individuals, respectively) .ConclusionStudy findings suggest that Persian version of FSFI-BC is a suitable instrument for sexual dysfunction screening in breast cancer survivors.

Relationship between Volitional and Non-Volitional Quadriceps Muscle Endurance in Patients with Chronic Obstructive Pulmonary Disease.

Volitional assessment of quadriceps muscle endurance is clinically relevant in patients with chronic obstructive pulmonary disease (COPD). However, studies that determine the construct validity of volitional tests by comparing them to non-volitional measures are lacking. Therefore, the aim of the current study is to evaluate the correlation between volitional and non-volitional quadriceps muscle endurance in patients with COPD. Quadriceps muscle endurance was evaluated in twenty-six patients with COPD. A volitional isometric and a volitional isokinetic protocol were performed on a computerised dynamometer to determine the isometric time and isokinetic work fatigue index, respectively. Non-volitional assessment of quadriceps muscle endurance was evaluated using repetitive electrical stimulations to establish the isometric muscle force decline. Sixteen patients (61 ± 8 years, 63% male, FEV1 47 (32-53)%) performed all three quadriceps endurance tests conforming to pre-defined test criteria. Both volitional isometric time and isokinetic work fatigue index did not significantly correlate with non-volitional muscle force decline (both p > 0.05). There was a strong correlation between volitional isometric time and isokinetic work fatigue index (rho = -0.716, p = 0.002). To conclude, this study suggests that volitional measures evaluate partly different aspects of quadriceps muscle endurance compared to non-volitional measures. Accordingly, these outcome measures cannot be used interchangeably.

"I Want It to Look Natural": Development and Validation of the FACE-Q Aesthetics Natural Module.

The concept of "natural" after a facial aesthetic treatment represents an understudied area. We added scales to FACE-Q Aesthetics to provide a means to measure this concept from the patient's perspective. The objective of this study was to develop and validate the FACE-Q Aesthetic Natural module. Concept elicitation interviews with people having minimally invasive treatments were conducted to explore the natural concept and develop scales. Patient and expert input refined scale content. An online sample (ie, Prolific) of people who had a facial aesthetic treatment was analyzed with Rasch measurement theory to examine psychometric properties. A test-retest reliability study was performed, and construct validity was examined. Interviews with 26 people were conducted. Three scales were developed and refined with input from 12 experts, 11 patients, and 184 online survey participants. Data from 1358 online participants provided evidence of scale reliability and validity. Reliability was high with person separation index, Cronbach alpha, and intraclass correlation coefficient values without extremes ≥0.82. Tests of construct validity confirmed that the scales functioned as hypothesized. Higher scores on the Expectations scale were associated with how important it was to have a natural look and movement after treatment. In addition, higher scores on the Natural Appearance and Natural Outcome scales correlated with better scores on other FACE-Q Aesthetics scales, and were associated with the face looking and feeling natural and with overall satisfaction with facial appearance. Many people seeking facial aesthetic treatments want to look natural after treatment. These new FACE-Q Aesthetics scales provide a means to measure the concept of natural from the patient's perspective.

Validation of the Retirement Resources Inventory in Persian: Assessing Psychometric Properties among Iranian Retirees.

Retirement resources are considered one of the key determinants of well-being and coping with the challenging situations of retirement courses. Therefore, due to the lack of a valid questionnaire for research and practice at the national level as well as international comparisons, this study was conducted to translate the original retirement resources inventory into Persian and assess the validity and reliability of the Persian version. The research employed a cross-sectional descriptive methodological approach, beginning with translating the questionnaire into Persian. Psychometric properties were evaluated through face, content, construct validity, and reliability tests. 335 participants were involved in assessing construct validity, while 30 participants contributed to the internal consistency test, and 20 took part in the test-retest reliability test. Data analysis was performed using SPSS Version 26 and AMOS 24 software. The exploratory factor analysis (EFA) revealed eight components with eigenvalues greater than 1, accounting for 46.68% of the variance, with no questions being removed. Confirmatory factor analysis (CFA) indicated that all items had a factor loading above 0.3, resulting in a final model with 35 items and eight factors, supported by fit indices (χ 2/df = 1.95, TLI: 0.87, IFI = 0.88, RMSEA = 0.05, GFI: 0.85). Reliability measures showed Cronbach's alpha coefficients ranging from 0.71 to 0.83 and an intraclass correlation coefficient (ICC) of 0.93. The study concludes that the Persian version of the RRI, encompassing 35 items across eight dimensions, is a valid and reliable tool for the Iranian retiree population. This validated inventory can be utilized in future national and international studies, particularly experimental ones, to develop well-being and retirement adjustment programs, thereby aiding in understanding and supporting Iranian retirees.

Content Validity Testing of a Novel Cognitive Screen, the Gaylord Occupational Therapy Cognitive (GOT-Cog), to Improve Inpatient Occupational Therapy Treatment Planning.

No single cognitive screen adequately captures all cognitive domains that are important for inpatient occupational therapy treatment planning. To quantify the content validity of a novel 22-item cognitive screen, the Gaylord Occupational Therapy Cognitive (GOT-Cog) screen, developed to better inform inpatient occupational therapy treatment planning. Delphi-style expert panel review. Long-term acute care hospital. The first panel was attended by four occupational therapists, two speech-language pathologists, one physician assistant, and two neuropsychologists; the second, by four occupational therapists, one speech-language pathologist, and one physician assistant. Each Delphi panel discussed the relevance, essentiality, and clarity of each item. After each discussion, panelists completed a content validity survey to summarize their evaluation of each item. On the basis of panelists' survey responses, item- and scale-level relevance, essentiality, and clarity were quantified by calculating the respective content validity index (CVI), content validity ratio (CVR), and content clarity index (CCI). Universal agreement (UA) and κ statistics were also calculated, as appropriate. Upon presenting the initial 23-item instrument covering 10 cognitive domains to the first Delphi panel, several questions were added, removed, or rewritten, resulting in a 22-item instrument representing nine domains. After the second panel, several questions were again rewritten, and the domains reorganized. All scale-level metrics improved, including CVI (from 0.87 to 1.0), UA (0.52 to 1.0), CVR (0.43 to 0.94), and CCI (2.26 to 2.92). GOT-Cog displays overall excellent content validity and can proceed to construct validity testing. Plain-Language Summary: By reporting on the content validity of the Gaylord Occupational Therapy Cognitive screen, this brief report begins the necessary process of evaluating the measure's overall validity and reliability.

Adaptation of Willpower Theories Scales to Turkish Culture and Investigation of Psychometric Properties

According to the Strength Model, willpower is derived from a limited resource, and using willpower reduces its capacity. However, subsequent studies have shown that the belief in whether the willpower is derived from a limited or unlimited resource affects its capacity. To measure these implicit beliefs about willpower, researchers have developed the Willpower Theories Scale (WTS) in three different areas. The purpose of this study is to conduct Turkish validity and reliability studies of the Strenuous Mental Activity (WTS-MA), Resistance to Temptations (WTS-RT), and Emotion Regulation (WTS-ER) Scales. For this purpose, data were collected from 498 people aged between 18-39. The psychometric properties of the scales were examined through validity and reliability analyses. According to the results of the Confirmatory Factor Analysis performed to test construct validity, it was observed that all three scales exhibited a good fit indexes. In terms of convergent validity, their relationships with the Brief Self-Control Scale and the WHO Well-Being Index-5 were examined. Following the reliability analysis, the Cronbach Alpha values of the scales were calculated as .69, .57, and .56 for WTS-MA, WTS-RT, and WTS-ER, respectively. Consequently, when evaluating the psychometric properties of all three scales, it can be concluded that the Turkish version is valid and reliable, making it suitable for future research.

Development of the "Social Participation Barriers in Patients With Diabetes" Questionnaire for Older Patients With Diabetes and Evaluation of its Reliability and Validity.

Objectives: To develop a questionnaire for evaluating the factors hindering social participation in older patients with diabetes (the Social Participation Barriers in Patients with Diabetes [SPBD] questionnaire) and assess its reliability and validity. Materials and Methods: This is a cross-sectional study. This study included outpatients aged ≥60 years having diabetes and undergoing treatment at the Ise Redcross Hospital. A draft questionnaire consisting of 20 questions was developed with reference to previous studies. Logistic regression analysis was conducted, and Cronbach's alpha coefficient was calculated. Exploratory factor analysis was conducted to test construct validity. Pearson's correlation coefficients between SPBD scores and frailty scores, social frailty scores and frequency of outings were calculated. Results: Overall, 353 patients were included in the analysis. After questions without an association in the logistic regression analysis were excluded and results of the exploratory factor analyses were obtained, 10 questions were excluded. As a result, we created a 10-item SPBD questionnaire. Cronbach's alpha coefficient was .87. The SPBD score was significantly associated with frequency of going out, and frailty. Conclusions: We created an SPBD questionnaire to assess barriers to social participation in older adult patients with diabetes. This study indicated the validity and reliability of the questionnaire.

Pengaruh Kepuasan Kerja Terhadap Kinerja Dokter yang Dimoderasi oleh Spiritualitas

Job satisfaction is a positive emotional condition as a result of job appraisal. Spirituality possessed by a doctor is an inner condition that grows because it interprets work in his life. This study aims to examine and explain the relationship between job satisfaction and physician performance, which is moderated by spirituality. From the questionnaires that were distributed, a total of 150 respondents were obtained consisting of general practitioners (71 people), doctors with Masters degrees (65 people), specialist doctors (9 people) and doctors with Doctoral education as many as 5 people. The doctors have worked for &lt; 5 years (63 people), 5-10 years (32 people), 10-20 years (31 people) and &gt; 20 years (24 people). The results of the construct validity test (job satisfaction) obtained data that there were 5 valid statement indicators. While the validity of spirituality obtained 4 valid data, and on the performance, parameters obtained 6 valid performance indicators. The results of the analysis obtained data that job satisfaction has a positive significant effect on the performance of doctors (P = 0.000). Spirituality has a positive significant effect on doctors' performance with a significance level of P=0.000. However, spirituality as a moderating variable has a negative effect, which means it reduces the effect of job satisfaction on performance. The spirituality factor reduces job satisfaction. It can be logically explained that job satisfaction is not solely a determinant of performance. Spirituality reflects the vocation of dedication as a doctor who has special knowledge to help human health and humanity. Spiritually, working doctors do not pursue job satisfaction merely, but there is a spirituality of dedication that aims to help save the souls of fellow human beings.

A Video-Based Procedure-Specific Competency Assessment Tool for Minimally Invasive Esophagectomy

Minimally invasive esophagectomy (MIE) is a complex procedure with substantial learning curves. In other complex minimally invasive procedures, suboptimal surgical performance has convincingly been associated with less favorable patient outcomes as assessed by peer review of the surgical procedure. To develop and validate a procedure-specific competency assessment tool (CAT) for MIE. In this international quality improvement study, a procedure-specific MIE-CAT was developed and validated. The MIE-CAT contains 8 procedural phases, and 4 quality components per phase are scored with a Likert scale ranging from 1 to 4. For evaluation of the MIE-CAT, intraoperative MIE videos performed by a single surgical team in the Esophageal Center East Netherlands were peer reviewed by 18 independent international MIE experts (with more than 120 MIEs performed). Each video was assessed by 2 or 3 blinded experts to evaluate feasibility, content validity, reliability, and construct validity. MIE-CAT version 2 was composed with refined content aimed at improving interrater reliability. A total of 32 full-length MIE videos from patients who underwent MIE between 2011 and 2020 were analyzed. Data were analyzed from January 2021 to January 2023. Performance assessment of transthoracic MIE with an intrathoracic anastomosis. Feasibility, content validity, interrater and intrarater reliability, and construct validity, including correlations with both experience of the surgical team and clinical parameters, of the developed MIE-CAT. Experts found the MIE-CAT easy to understand and easy to use to grade surgical performance. The MIE-CAT demonstrated good intrarater reliability (range of intraclass correlation coefficients [ICCs], 0.807 [95% CI, 0.656 to 0.892] for quality component score to 0.898 [95% CI, 0.846 to 0.932] for phase score). Interrater reliability was moderate (range of ICCs, 0.536 [95% CI, -0.220 to 0.994] for total MIE-CAT score to 0.705 [95% CI, 0.473 to 0.846] for quality component score), and most discrepancies originated in the lymphadenectomy phases. Hypothesis testing for construct validity showed more than 75% of hypotheses correct: MIE-CAT performance scores correlated with experience of the surgical team (r = 0.288 to 0.622), blood loss (r = -0.034 to -0.545), operative time (r = -0.309 to -0.611), intraoperative complications (r = -0.052 to -0.319), and severe postoperative complications (r = -0.207 to -0.395). MIE-CAT version 2 increased usability. Interrater reliability improved but remained moderate (range of ICCs, 0.666 to 0.743), and most discrepancies between raters remained in the lymphadenectomy phases. The MIE-CAT was developed and its feasibility, content validity, reliability, and construct validity were demonstrated. By providing insight into surgical performance of MIE, the MIE-CAT might be used for clinical, training, and research purposes.

The ad-libitum taste test as measure of momentary alcohol use in the laboratory: an investigation of construct validity and confounding factors

RationaleThe ad-libitum taste test is a widely used covert measure of motivation to consume alcohol in the laboratory. However, studies on its construct validity and potential confounding factors are scarce.ObjectivesThis study aimed to evaluate the construct validity of the ad-libitum taste test by examining the association of ad-libitum alcohol consumption with typical alcohol use and craving, and investigating potential moderation by trait anxiety, depressiveness, current mood, and drinking motives.MethodsA sample of 264 young male individuals were offered two 0.33 l glasses of beer. Participants were instructed to rate the characteristics of each drink, while the percentage of beverages containing alcohol consumed was assessed. Associations of ad-libitum consumption with typical alcohol use and craving were assessed using non-parametric and piecewise regressions. Moreover, moderator analysis with trait anxiety, depressiveness, current mood, and drinking motives was carried out.ResultsAd-libitum alcohol consumption was associated with typical alcohol use and alcohol craving. However, these associations decreased at high consumption levels. Associations between ad-libitum consumption, typical alcohol use, and craving were stable across several conditions, except that the association between ad-libitum consumption and craving increased with higher social, conformity, and coping drinking motives.ConclusionsThe ad-libitum taste test appears to be a valid measure of the motivation to drink alcohol in laboratory studies in young male adults, although this validity might be compromised at high levels of ad-libitum consumption. Consideration of these factors can contribute to further refining the ad-libitum taste test as a valuable tool for assessing motivation to consume alcohol in laboratory studies.
