Analysing the influencing factors of on-line studying engagement of preparatory international students: A case study of the science and technology Chinese course

With the rapid development of network technology, cross-regional on-line higher education is becoming one of the mainstream directions of distance education development. The effectiveness of on-line studying is significantly influenced by the level of learning engagement, and research on this topic can help learners by providing them with process-oriented learning support and targeted teaching interventions. Using the example of on-line Science and Technology Chinese Course for preparatory international students at four universities in China, this study collected self-reported data from 463 students using a survey method. The questionnaire was divided into two parts: the on-line studying engagement scale and the factors influencing on-line studying engagement. Descriptive statistical analysis and differential testing were conducted on the data using SPSS software, and the structural validity of the questionnaire was tested using AMOS software. With the assistance of Smart PLS, a model of the influencing factors of on-line studying engagement was constructed to explore the relationship between on-line studying engagement and its influencing factors. The study found that: The overall level of engagement in on line studying for preparatory international students is above average. In demographic factors, apart from gender, all other variables have a significant impact on on-line studying. Student-level factors will have a more significant positive impact on the degree of on-line studying engagement of preparatory international students. Among them, academic self-efficacy, basic psychological needs satisfaction, the difficulty of the on-line course, and completion of the assignment have a significant positive effect. The influence of teacher-level factors on behavioral engagement and emotional engagement is stronger than that of student-level factors. However, the emotional support of teacher-level factors, the on-line environment of environmental-level factors, and the perceived usefulness of technology of teacher-level factors have a certain negative impact on engagement in online studying. According to the research results, this paper puts forward the optimization strategies of accelerating the update frequency of Chinese learning materials, strengthening the input of on-line emotional support, and holding language learning activities with cultural characteristics. This study makes an in-depth analysis of the influencing factors of preparatory international students’ on-line Chinese studying engagement, and puts forward the optimization strategies to improve the quality of on-line studying, to provide theoretical and practical reference for the development of cross-regional on-line higher education.

Development of a new health-related quality of life measure for people with diabetes who experience hypoglycaemia: the Hypo-RESOLVE QoL

Aims/hypothesisValid and reliable patient-reported outcome measures are vital for assessing disease impact, responsiveness to healthcare and the cost-effectiveness of interventions. A recent review has questioned the ability of existing measures to assess hypoglycaemia-related impacts on health-related quality of life for people with diabetes. This mixed-methods project was designed to produce a novel health-related quality of life patient-reported outcome measure in hypoglycaemia: the Hypo-RESOLVE QoL.MethodsThree studies were conducted with people with diabetes who experience hypoglycaemia. In Stage 1, a comprehensive health-related quality of life framework for hypoglycaemia was elicited from semi-structured interviews (N=31). In Stage 2, the content validity and acceptability of draft measure content were tested via three waves of cognitive debriefing interviews (N=70 people with diabetes; N=14 clinicians). In Stage 3, revised measure content was administered alongside existing generic and diabetes-related measures in a large cross-sectional observational survey to assess psychometric performance (N=1246). The final measure was developed using multiple evidence sources, incorporating stakeholder engagement.ResultsA novel conceptual model of hypoglycaemia-related health-related quality of life was generated, featuring 19 themes, organised by physical, social and psychological aspects. From a draft version of 76 items, a final 14-item measure was produced with satisfactory structural (χ2=472.27, df=74, p<0.001; comparative fit index =0.943; root mean square error of approximation =0.069) and convergent validity with related constructs (r=0.46–0.59), internal consistency (α=0.91) and test–retest reliability (intraclass correlation coefficient =0.87).Conclusions/interpretationThe Hypo-RESOLVE QoL is a rigorously developed patient-reported outcome measure assessing the health-related quality of life impacts of hypoglycaemia. The Hypo-RESOLVE QoL has demonstrable validity and reliability and has value for use in clinical decision-making and as a clinical trial endpoint.Data availabilityAll data generated or analysed during this study are included in the published article and its online supplementary files (https://doi.org/10.15131/shef.data.23295284.v2).Graphical

Performance of the Modified Caregiver Strain Index in a Sample of Black and White Persons Living With Dementia and Their Caregivers.

This study examined the performance of the Modified Caregiver Strain Index (MCSI) in a sample of Black and White caregivers of persons living with dementia. Data on 153 dyads enrolled in the Care Ecosystem dementia care management program were analyzed, including sociodemographic variables, dementia severity, and caregiver burden and wellbeing. Factor structure, item-response patterns, and concurrent validity were assessed across racial groups. Differences between Black and White caregivers included gender, dyad relation, and socioeconomic disadvantage. Factor structure and item loadings varied by racial cohort, with parameters supporting a 3-factor model. For Black caregivers, finances and work, emotional and physical strain, and family and personal adjustment items loaded together on individual factors. For White caregivers physical and emotional strain items loaded on separate factors, although personal and family adjustment items loaded with work and financial strain items. Item-level analysis revealed differences between groups, with Black caregivers endorsing physical strain to a greater degree (p = .003). Total MCSI scores were positively correlated with concurrent measures like the PHQ-9 (White: r = 0.67, Black: r = 0.54) and the GAD-2 (White: r = 0.47, Black: r = 0.4), and negatively correlated with self-efficacy ratings (White: r = -0.54, Black: r = -0.55), with a p < .001 for all validity analysis. The MCSI displayed acceptable statistical performance for Black and White caregivers of persons living with dementia and displayed a factor structure sensitive to cultural variations of the construct. Researchers results highlight the inherent complexity and the relevance of selecting inclusive measures to appropriately serve diverse populations.

Cross-cultural evaluation of the Michigan Hand Outcomes Questionnaire: a systematic review

This systematic review aims to provide a comprehensive synthesis and in-depth analysis of the quality of the different cross-cultural versions of the MHQ. This study was conducted using Pubmed, Web of Science, CINAHL and SCOPUS databases to identify cross-cultural validation studies of the MHQ. Methodological quality, quality of evidence and criteria for good measurement properties of these studies were applied for each psychometric property. Quality assessment and data extraction were performed independently by two reviewers according to the COnsensus-based Standards for selection of health Measurement INstruments (COSMIN) guidelines. A total of 493 articles were identified, of which 22 were included and 20 were analysed.Of the six properties analysed, responsiveness and hypothesis testing for construct validity had the highest methodological quality and quality of evidence, and met the criteria for good measurement properties. The lowest quality properties were measurement error and internal consistency. The different cross-cultural versions of the MHQ were found to be reliable, valid and able to detect clinical change. The lack of development of measurement error, formulation of an a priori hypothesis or structural validity affects the detection of small clinical changes and their discriminative capacity.

Translation and cross-cultural adaptation of the posttraumatic stress disorder checklist for DSM-5 for the Thai population

ObjectiveThis study aimed to perform a transcultural translation of the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) and assess its reliability within the Thai context. MethodsThe PCL-5 underwent a comprehensive translation process, including forward and backward translation, assessment by an expert panel, and comprehension testing by 10 patients with posttraumatic stress disorder (PTSD). The internal consistency of the overall scale and its subscales was examined using a sample of 100 patients with psychiatric disorders. Test-retest reliability was tested on Day 0 and Day 14. Confirmatory factor analyses were performed to assess structural validity and goodness-of-fit. ResultsExperts’ assessment of item-objective congruence indicated a satisfactory alignment of all items. The patients with PTSD demonstrated a strong understanding of the questionnaire. The translated PCL-5 exhibited excellent internal consistency (α = 0.96) with robust internal consistency of all subscales (α ranging from 0.86 to 0.91). The test-retest reliability was high (r = 0.82). Among the three structural models tested, the seven-factor Hybrid model provided the best fit to the data. Notably, patients with personality disorders scored the highest. ConclusionsThe Thai version of the PCL-5 demonstrates reliability, making it a valuable instrument for clinical application and future research among the Thai population. Patients with comorbid personality disorders may score higher on the PCL-5.

The Patient Activation Measure-13 (PAM-13) in an oncology patient population: psychometric properties and dimensionality evaluation

BackgroundAccurate assessment and enhancement of health-related skills among oncology patients are pivotal for optimizing cancer care. The Patient Activation Measure (PAM-13), a questionnaire designed to reflect an individual’s knowledge, skills, and confidence in self-healthcare management, has been validated across diverse countries and settings. Concerns have been raised regarding the cross-situational applicability, as patients with specific diseases and cultural backgrounds interpret questionnaire items differently. This study aimed to examine the structural validity and psychometric properties of the PAM-13 in an oncological patient cohort.MethodsBaseline data from a longitudinal non-randomized controlled study involving cancer out-patients (n = 1,125) from Comprehensive Cancer Centres in Southern Germany were analysed. The German version of the PAM-13 was employed. With classical test and item response theory methods data quality, reliability, convergent and structural validity, as well as psychometric properties were assessed. Exploratory (EFA) and confirmatory factor analyses (CFA) were employed to investigate the postulated unidimensionality of the underlying construct. With a partial credit model (PCM) we examined item fit, targeting, local independence and differential item functioning.ResultsParticipants were predominantly female (73.0%) with a breast cancer diagnosis (41.3%). While items were generally well-accepted, ceiling effects were observed and a high mean PAM-13 score (69.7, SD = 14.2) was noted, potentially compromising responsiveness to interventions. Reliability was adequate (Cronbach’s α = 0.81), person and item separation reliability were good to excellent (0.81 and 0.99, respectively). Explorations of the unidimensionality of the construct (EFA, CFA, PCM) yielded inconclusive results, hinting towards a two-factor solution. Item difficulty rankings deviated from the original. No differential item functioning was identified, and local independence was confirmed.ConclusionsWhile the PAM-13 serves as a valuable instrument for comprehending and promoting health-related skills in cancer patients, the identification of ceiling effects, disordered item-difficulty rankings, and inconclusive findings regarding unidimensionality contribute to the expanding body of evidence, emphasizing the dependency of PAM-13’s validity and reliability on distinctive characteristics within the population under investigation. Future research should prioritize refining or adding PAM-13 items to better capture the specific health-related challenges within diverse populations, paving the way for more effective patient engagement strategies in oncology.Trial registration numberDRKS00021779

TURKISH ADAPTATION OF THE PERCEPTION OF ANOMIE SCALE: PSYCHOMETRIC PROPERTIES, VALIDITY AND RELIABILITY

Anomie describes a situation in which society does not meet individuals' expectations and does not offer moral standards and a just and reasonable social context. Perceived anomie is related to numerous psychological variables, such as political decisions and self-esteem. This study aims to adapt and assess the validity and reliability of the Turkish version of the Perception of Anomie Scale. The sample consisted of 332 participants (189 women) aged between 18-66. For convergent validity we used Group Integration Scale and Belief in a Dangerous World Scale, for discriminant validity we used General Belief in a Just World Scale and Social Dominance Orientation Scale, for predictive validity we used Life Satisfaction Scale and Importance of Identity Scale. The results demonstrated the structural validity of the scale and presented adequate evidence for the measurement validity of the Turkish version of the Perception of Anomie Scale.

Which Scale to Assess Pain Self-efficacy Shows Better Measurement Properties in Chronic Low Back Pain? A Head-To-Head Comparison Study

ObjectiveTo compare the quality of the measurement properties of Pain Self-Efficacy Questionnaire (PSEQ)-10, PSEQ-4, PSEQ-2, Chronic Pain Self-Efficacy Scale (CPSS) long-form, and CPSS short-form (CPSS-SF) in patients with chronic low back pain (CLBP). DesignCross-sectional and longitudinal studies (measurement properties). SettingOutpatient rehabilitation. ParticipantsParticipants (N=245) with nonspecific CLBP (18-60y, 63% women) were enrolled in this study. InterventionsNot applicable. Main Outcome MeasuresPain self-efficacy questionnaires were administered on 3 occasions: baseline assessment, 1 week after the first assessment (reliability), and after an 8-week exercise program (responsiveness). The intraclass correlation coefficient (ICC) and Cronbach α were used to assess reliability and internal consistency, respectively. Pearson correlation and confirmatory factor analyses were used to assess construct validity. The area under the curve and hypothesis testing were used to assess responsiveness. ResultsNo difference was observed for all the questionnaires regarding internal consistency (Cronbach α>.7), criterion validity (r>.88), and reliability (ICC>.7). The scales confirmed >75% of the hypotheses for the construct validity, except for CPSS-SF. PSEQ-2 did not meet the criterion for structural validity. PSEQ-10 met all the criteria for good measurement properties according to Consensus-Based Standards for the Selection of Health Measurement Instruments. ConclusionsIt was not possible to calculate structural validity for PSEQ-2, CPSS-SF did not meet the criterion for suitable hypothesis testing for construct validity, and all the questionnaires did not show suitable measurement error, except for the PSEQ-10. Hence, the PSEQ-10 was the unique scale that met all the criteria for good measurement properties for assessing pain self-efficacy in CLBP.

Psychometric Properties of the Weight Loss Readiness Test in Active Duty Military Personnel Enrolled in a Weight Management Trial.

The Weight Loss Readiness Test (WLRT) was developed to encourage consideration of factors influencing readiness to engage in weight loss. The WLRT is used clinically, most notably to assess motivation before initiating Navy weight management programs, yet little is known about its psychometric properties. This study examined the reliability, convergent and predictive validity, and factor structure of the WLRT in a sample of active duty service members enrolling in a Navy-based weight management program (N = 178, identified as female = 61%, mean age = 29.7 years, mean baseline body mass index = 33.1 kg/m2). All procedures were approved by the respective Institutional Review Boards and research committees. Exploratory factor analysis revealed a 5-factor structure explaining 52% of the variance that best fit the data with low to moderate correlations between factors: (1) Motivation, (2) Exercise-Related Confidence, (3) Non-Exercise Confidence, (4) Cues, and (5) Anticipated Satisfaction. Internal reliability of subscales was acceptable to good (α = 0.755-0.903). Generally, convergent validity was found between the identified subscales and other measures of motivation, confidence, and disinhibited eating in expected directions. No relationships were found between the subscales and predictive validity outcomes (weight change, program attendance). Results indicate adequate structural and convergent validity in the WLRT, but that weight loss readiness, as measured by the WLRT, does not provide predictive validity regarding weight loss or attendance outcomes in this sample. Nonetheless, this measure offers clinical utility in fostering thoughtful conversations about weight loss. The WLRT uniquely focuses on long-term maintenance of behavior change and differentiates between exercise-related and non-exercise confidence. Future studies should further probe the utility of this measure in other populations and the contexts in which it is being used.

Examining the structural validity of the teacher-rated SSIS-RS and SSIS SEL scales

ABSTRACT The Social Skills Improvement System-Rating Scales (SSIS-RS) and the Social Skills Improvement System Social and Emotional Learning Edition (SSIS SEL) are rating scales used to assess social behavior in children and adolescents. While the SSIS-RS is well-regarded and used worldwide, the SSIS SEL is establishing foothold. In the current study, we used confirmatory factor analyses to investigate the structural validity of teacher-reported social skills in both the SSIS-RS and SSIS SEL in a large sample of Norwegian first-grade students (n = 879). Our evaluation indicates that the six-factor SSIS SEL models displayed superior fit compared to the seven-factor structures of SSIS-RS in our data. Results provide evidence of (a) several excessive factor correlations in both structures, (b) a few items overlapping in content, and (c) five items that appeared statistically distinct from the overall concepts of social skills (SSIS-RS) and social and emotional competency (SSIS SEL).

Translation, validation, and comparison of genetic knowledge scales in Greek and German.

Introduction : Advances in biosciences have significantly expanded our knowledge and capabilities in medicine and technology. Genetic tests can now predict hereditary predisposition or susceptibility to diseases, while gene-editing tools like CRISPR/Cas enable easy repair of disease genes in both somatic and germline cells, ensuring permanent genome correction. Despite these advancements, there is a shortage of valid instruments for studying the knowledge about these technologies. To fill this gap, our study aims to translate and validate various scales to effectively measure the public's knowledge of genetics. Methods: A convenience sample of N = 567 (Germany n = 317, Greece n = 250) participants completed a Google Forms questionnaire between December 2022 and June 2023, which included the General Knowledge of Genes and Heredity (GKGH), Knowledge about Gene-Environment Interaction (KGEI), and Knowledge of Modern Genetics and Genomics (KMGG) questionnaires. Analyses included internal consistency, structural validity, construct validity, and retest reliability with a subset of n = 72 (DE) and n = 50 (GR). Correlation analyses and group differences were evaluated for gender, education, religiosity, age, prior experience with genetic testing, and preferences toward potential providers of genetic testing. This study used the STROBE checklist for reporting. Results: The GKGH exhibited low values in internal consistency and item analysis, along with a ceiling effect within the German group. However, it demonstrated good values in retest and construct validity. In the Greek group, all properties were highly satisfactory. The KMGG consistently displayed excellent properties across all analyses, whereas the KGEI only showed convincing results in construct validity and item analysis. Discussion: The GKGH and KMGG demonstrated strong psychometric properties with varying difficulty levels dependent on the sample, with the German sample demonstrating a notably higher understanding of genetic technologies. Despite displaying acceptable properties, the KGEI fell short of measuring what its title suggests. Participants' level of education showed a significant correlation with knowledge of genetic technologies, and only in the Greek sample did experiences with genetic tests influence knowledge. Preferences regarding availability of genetic testing are comparable between the two countries, with variations influenced by factors such as age, gender and religiosity.

Longitudinal Analysis and Latent Growth Modeling of the Modified Hip Dysfunction and Osteoarthritis Outcome Score for Joint Replacement (HOOS-JR).

The Hip Dysfunction and Osteoarthritis Outcome Score for Joint Replacement (HOOS-JR) was developed as a short-form survey to measure progress after total hip arthroplasty (THA). However, the longitudinal validity of the scale structure pertaining to the modified five-item HOOS-JR has not been assessed. Therefore, the purpose of this study was to evaluate the structural validity, longitudinal invariance properties, and latent growth curve (LGC) modeling of the modified five-item HOOS-JR in a large multi-site sample of patients who underwent a THA. A longitudinal study was conducted using data from the Surgical Outcome System (SOS) database. Confirmatory factor analyses (CFAs) were conducted to assess the structural validity and longitudinal invariance across five time points. Additionally, LGC modeling was performed to assess the heterogeneity of the recovery patterns for different subgroups of patients. The resulting CFAs met most of the goodness-of-fit indices (CFI = 0.964-0.982; IFI = 0.965-0.986; SRMR = 0.021-0.035). Longitudinal analysis did not meet full invariance, exceeding the scalar invariance model (CFIDIFF = 0.012; χ2DIFF test = 702.67). Partial invariance requirements were met upon release of the intercept constraint associated with item five (CFIDIFF test = 0.010; χ2DIFF = 1073.83). The equal means model did not pass the recommended goodness-of-fit indices (CFIDIFF = 0.133; χ2DIFF = 3962.49). Scores significantly changed over time, with the highest scores identified preoperatively and the lowest scores identified at 2- and 3-years postoperatively. Upon conclusion, partial scalar invariance was identified within our model. We identified that patients self-report most improvements in their scores within 6 months postoperatively. Females reported more hip disability at preoperative time points and had faster improvement as measured by the scores of the modified five-item HOOS-JR.

Validity and Reliability of the Empowered Veteran Index-Short Form (EVI-SF)

ABSTRACT Purpose Veteran empowerment may include connection, community impact, and personal growth. At least one valid and reliable tool has been developed to measure the aforementioned framework: the empowered veteran index (EVI). However, there is a need for a shorter measure to prevent survey fatigue. Materials and methods We recruited military veteran members of a nonprofit (n = 316), The Mission Continues, for participation in this cross-sectional online survey study. Participants completed the 35-item EVI. A short form of the EVI (EVI-SF) was developed through bifactor confirmatory factor analysis (CFA). Results The 10-item EVI-SF model demonstrated satisfactory performance (χ2 p = 0.68, SRMR = 0.02, RMSEA = 0.01, CFI = 0.99, TLI = 0.99). All factor loadings in this model were ≥ 0.30, providing evidence for the validity of the interval structure. Internal consistency reliability was good for all three subscales (omegas >0.7). Discussion Analysis of the EVI-SF showed that the instrument was valid and reliable. The EVI-SF contains 10 items with seven-point Likert scale response options. Use of the instrument may provide for the opportunity to measure empowerment of military veterans. Conclusion This study provides preliminary psychometric validation of the EVI-SF.

Evaluating the psychometric properties of the simplified Chinese version of PROMIS-29 version 2.1 in patients with hematologic malignancies

The Patient-Reported Outcomes Measurement Information System 29-item Profile version 2.1 (PROMIS-29 V2.1) is a widely utilized self-reported instrument for assessing health outcomes from the patients’ perspectives. This study aimed to evaluate the psychometric properties of the PROMIS-29 V2.1 Chinese version among patients with hematological malignancy. Conducted as a cross-sectional, this research was approved by the Medical Ethical Committee of the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (registration number QTJC2022002-EC-1). We employed convenience sampling to enroll eligible patients with hematological malignancy from four tertiary hospitals in Tianjin, Shandong, Jiangsu, and Anhui province in China between June and August 2023. Participants were asked to complete a socio-demographic information questionnaire, the PROMIS-29 V2.1, and the Functional Assessment of Cancer Therapy-General (FACT-G). We assessed the reliability, ceiling and floor effects, structural, convergent discriminant and criterion validity of the PROMIS-29 V2.1. A total of 354 patients with a mean age of 46.93 years was included in the final analysis. The reliability of the PROMIS-29 V2.1 was affirmed, with Cronbach’s α for the domains ranging from 0.787 to 0.968. Except sleep disturbance, the other six domains had ceiling effects, which were seen on physical function (26.0%), anxiety (37.0%), depression (40.4%), fatigue (18.4%), social roles (18.9%) and pain interference (43.2%), respectively. Criterion validity was supported by significant correlations between the PROMIS-29 V2.1 and FACT-G scores, as determined by the Spearman correlation test (P < 0.001). Confirmatory factor analysis (CFA) indicated a good model fit, with indices of χ2/df (2.602), IFI (0.960), and RMSEA (0.067). The Average Variance Extracted (AVE) values for the seven dimensions of PROMIS-29 V2.1, ranging from 0.500 to 0.910, demonstrated satisfactory convergent validity. Discriminant validity was confirmed by ideal √AVE values. The Chinese version of the PROMIS-29 V2.1 profile has been validated as an effective instrument for assessing symptoms and functions in patients with hematological malignancy, underscoring its reliability and applicability in this specific patient group.

Phylum-level studies of bacterial cutinases for unravelling enzymatic specificity toward PET degradation: an in silico approach.

The overwhelming use of PET plastic in various day-to-day activities led to the voluminous increase in PET waste and growing environmental hazards. A plethora of methods have been used that are associated with secondary pollutants. Therefore, microbial degradation of PET provides a sustainable approach due to its versatile metabolic diversity and capacity. The present work highlights the cutinase enzyme's role in PET degradation. This study focuses on the bacterial cutinases homologs screened from 43 reported phylum of bacteria. The reported bacterial cutinases for plastic degradation have been chosen as reference sequences, and 917 sequences have shown homology across the bacterial phyla. The dienelactone hydrolase (DLH) domain was identified for attaining specificity towards PET binding in 196 of 917 sequences. Various computational tools have been used for the physicochemical characterization of 196 sequences. The analysis revealed that most selected sequences are hydrophilic, extracellular, and thermally stable. Based on this analysis, 17 sequences have been further pursued for three-dimensional structure prediction and validation. The molecular docking studies of 17 selected sequences revealed efficient PET binding with the three sequences derived from the phylum Bacteroidota, the lowest binding energy of -5.9kcal/mol, Armatimonadota, and Nitrososphaerota with -5.8kcal/mol. The two enzyme sequences retrieved from the phylum Bacteroidota and Armatimonadota are metagenomically derived. Therefore, the present studies concluded that there is a high probability of finding cutinase homologs in various environmental resources that can be further explored for PET degradation.

Clarifying the longitudinal factor structure, temporal stability, and construct validity of Go/No-Go task-related neural activation across adolescence and young adulthood

This study aimed to clarify the psychometric properties and development of Go/No-Go (GNG) task-related neural activation across critical periods of neurobiological maturation by examining its longitudinal stability, factor structure, developmental change, and associations with a computational index of task-general cognitive control. A longitudinal sample (N=289) of adolescents from the Michigan Longitudinal Study was assessed at four time-points (mean number of timepoints per participant=2.05; standard deviation=0.89) spanning early adolescence (ages 10−13) to young adulthood (22−25). Results suggested that regional neural activations from the “successful inhibition” (SI>GO) and “failed inhibition” (FI>GO; error-monitoring) contrasts are each described well by a single general factor. Neural activity across both contrasts showed developmental increases throughout adolescence that plateau in young adulthood. Neural activity metrics evidenced low temporal stability across this period of marked developmental change, and the SI>GO factor showed no relations with a behavioral index of cognitive control. The FI>GO factor displayed stronger criterion validity in the form of significant, positive associations with behaviorally measured cognitive control. Findings emphasize the utility of well-validated psychometric methods and longitudinal data for clarifying the measurement properties of functional neuroimaging metrics and improving measurement practices in developmental cognitive neuroscience.

Development and validation of career decision making proficiency scale

The purpose of the present research was to develop and examine the psychometric properties of the Career Decision Making Proficiency Scale (CDMPS). The new tool amalgamates various conceptual domains of career exploration process and validates its usage for students and young adults (N=565). The researcher used a survey research design that involved the theoretical evaluation by experts, mandating two subscale divisions for the original 40 items. A deductive approach was considered for the scale development. The content validity assessment by means of CVR- Lawshe’s Test, Fleiss’ Kappa statistics, and the CVI-proportion agreement method retained 34 items. R Studio software was used for dimension reduction techniques and inter-factor bi-variate correlations. The results of the item analysis confirmed 30 items clustered into five dormant constructs. The reliability coefficients of the two sub-scales were found to be high (α= 0.80 and 0.87). Furthermore, the exploratory factor analysis explained 52.45 percent and 50.99 percent of total variance, confirming the factorial internal structural validity of the two sub-scales, respectively. The scale can be administered by career and school counsellors to guide students with their career decisions, to assess career decision difficulties faced by weak students and potential dropouts or repeaters, and to assess students’ confidence, motivation, and abilities in handling problematic situations at the time of deciding a career path.

Psychometric Properties of Career Decision-Making Difficulties Questionnaire: Lithuanian Version

Valid and reliable methods are needed to assess the difficulties young people often face in making career-related decisions. A cross-sectional study was conducted to test the psychometric characteristics (internal consistency, discriminant, convergent and structural validities) of the Lithuanian version of the Career decision-making difficulties questionnaire (Gati et al., 1996) in a sample of Lithuanian students (N = 255). The results revealed that the Lithuanian version of Career decision-making difficulties has good internal consistency. Adequate convergent validity was confirmed by finding statistically significant positive relationships with indecisiveness, and discriminant validity was confirmed by finding statistically significant negative relationships with career self-efficacy. Finally, structural validity was confirmed by confirmatory factor analysis, which revealed that a 10-factor structure was the most appropriate. The results of the research showed that the Lithuanian version of the Career decision-making difficulties questionnaire is a suitable measurement tool, but further studies on the evaluation of the scale are needed.

Psychometric validation of the Danish version of the Major Depression Inventory using data from the Lolland-Falster health study (LOFUS)

Purpose The Major Depression Inventory (MDI) is a widely used self-rating depression scale commonly in primary care in Denmark. It has not been subject to robust psychometric validation in a general population setting. The aim of this study was to evaluate the psychometric measurement properties of the MDI when applied in the general population. Methods We evaluated statistical psychometric validity using modern test theory (confirmatory factor analysis, item response theory models and Rasch measurement theory) testing local independence and differential item function across groups defined by gender, age, education, and chronic disease status. Separate analyses across different strata and across different statistical models were employed. Results Regarding structural validity we consistently identified local dependence for the item two pairs (MDI2,MDI3) and (MDI4,MDI5) across strata. This result was confirmed by bifactor CFA models and item screening. We further identified substantial differential item functioning with respect to age group and with respect to chronic disease. We identified quantified the magnitude of this lack of measurement invariance. Conclusion The MDI is psychometrically valid in homogenous sub populations, but the disclosed evidence of local dependence means that published estimates of its reliability cannot be trusted. The lack of measurement invariance means that the instrument cannot be used to compare individuals or groups unless they are similar in terms of age group and chronic disease status.

Psychometric properties of the Norwegian version of the Strength and Difficulties Questionnaire in a preschool sample

Purpose The Strength and Difficulties Questionnaire (SDQ) is widely used internationally, however less so in preschool populations and validations studies are thus needed. This study examined the psychometric properties of the Norwegian version parent report of the SDQ – preschool version (SDQ 2–4). Materials and methods Parents of 289 Norwegian children in the age span 1–6 years old filled out the SDQ 2–4, the Child Behavior Checklist (CBCL), and background information. Internal consistency, factor structure, and convergent validity were assessed. Results The results showed satisfying internal consistency for the total difficulties score, but worse for some of the subscales. The five-factor structure showed a good fit. Good convergent and divergent validity was found in terms of correlations with CBCL. Sex differences were found on all scales, boys scoring higher on all problem scales. Conclusions The SDQ 2–4 can be a promising instrument to screen for emotional and behavioral difficulties among Norwegian preschoolers, particularly in high-risk populations.
