Fit Entropy-Based Dynamic Communication Resource Slicing-Optimization Method in Smart Distribution Grids on the Medium-Low-Voltage Side.

With the rapid development of new energy and smart technology, the demand for inter-device communication in medium-low-voltage smart distribution grids has sharply increased, leading to a surge in the variety and quantity of communication services. To meet the needs of diverse and massive communication services, deploying service function chains to flexibly combine virtual resources has become crucial. This paper proposes an optimization method based on fit entropy and network utility to address the limited communication network resources in medium-low-voltage smart distribution grids. This was conducted by modeling the distribution grid as a three-domain model consisting of a service domain, a logical domain, and a physical domain and transforming it into a hierarchical bipartite hypergraph-matching problem, which is a complex combinatorial optimization problem. This paper introduces two matching optimization algorithms: "business domain-logic domain-physical domain integration" and "service domain-logic domain, logic domain-physical domain two-stage", which effectively address this problem based on fit entropy and utility. The simulation results demonstrate that these algorithms significantly improve service success rates and resource utilization, enhancing overall network utility.

Venovenous Extracorporeal Membrane Oxygenation Candidacy Decision-Making: Lessons and Hypotheses From a Single-Center Observational Analysis

BackgroundUtilization of veno-venous extracorporeal membrane oxygenation (V-V ECMO) is increasing, but candidacy selection processes are variable and subject to bias. Research QuestionWhat are the reasons behind V-V ECMO candidacy decisions, and are decisions made consistently across patients? Study Design and MethodsProspective observational study of all patients, admitted or outside hospital referrals, considered for V-V ECMO at a tertiary referral center. Relevant clinical data and reasons for candidacy determination were cross-referenced with other non-candidates and candidates and qualitatively assessed. ResultsEighty-one consultations resulted in 44 (54%) non-candidates, 29 (36%) candidates (9 were subsequently cannulated), and 8 (10%) deferred decisions. Fifteen unique contraindications were identified, variably present across all patients. Five contraindications were invoked as the sole reason to decline a patient. In patients with three or more contraindications, additional contraindications were cited even if their severity was relatively minor. All but four contraindications invoked to decline a patient were non-prohibitive for at least one other candidate. Contraindications documented in non-candidates were present but not mentioned in 21 (47%) other non-candidates. Twenty-six (90%) candidates had at least one contraindication that was prohibitive in a non-candidate, including a contraindication that was the sole reason to decline. Contraindications were proposed as informing three prognostic domains, through which patterns of inconsistency could be better understood: (1) irreversible underlying pulmonary process, (2) unsurvivable critical illness, and (3) clinical condition too compromised for meaningful recovery. InterpretationECMO candidacy decisions are inconsistent. We identified four patterns of inconsistency in our center and propose a three-domain model for understanding and categorizing contraindications, yielding five lessons that may improve candidacy decision processes until further research can more definitively guide practice.

Quality of Life in Childhood Immune Thrombocytopenia: Revision of the Kids' ITP Tools (KIT)

Introduction New treatment approaches have emerged for pediatric ITP over the years, potentially impacting the health-related quality of life (HRQoL) of affected individuals. The Kids' ITP Tools (KIT) (Child self-report/Parent proxy-report and Parent impact-report) have gained international attention as valid tools for monitoring HRQoL in children with ITP and the impact on their parents. The questionnaires were recently updated to reflect changes in clinical management. However, it has also become common practice to evaluate the impact of new therapies using domain scales of QOL (i.e., sub-categories), which are not yet available for the KIT. Thus, the primary objective of this study was to establish domain scales for the KIT 2.0 that accurately quantify and identify specific aspects of HRQoL that are impacted in children with ITP and their parents. Methods The study was conducted in two sequential phases. Phase 1 involved ITP experts identifying key conceptual domains for the KIT questionnaires based on their clinical experiences. An online survey (“card sort survey”) was distributed, and experts sorted the current KIT 2.0 questions into domains, with domain headings suggested as well. Phase 2 involved a statistical approach (i.e., exploratory factor analysis (EFA)) to yield models with different number of domains. Data from children with ITP and their parents was utilized to develop the models, and the data was specifically from three previous international multicentre studies: ITP Consortium of North America (ICON1 study), UK Children's Hospital (UK ITP Paediatric Registry), and the Children's Hospital of Eastern Ontario (KIT international validation). Results In Phase 1, 24 experts completed the Child self-report card-sort survey, while 12 experts completed the Parent impact survey. There were two models that were derived for the Child Self-Report, with one having three domain scales and the other with four domain scales. The Parent Impact resulted in only one model that had three domain scales. In Phase 2, exploratory factor analysis (EFA) resulted in three models for each of the three questionnaires (Table 1), with the final models selected from the EFA and based on clinical interpretability. The four-domain model was selected for the Child Self-Report. The model had a higher Tucker Lewis Index (TLI) score and cumulative percentage of variance compared to the three-domain model. Though the cumulative percentage of variance was higher for the six-domain model, the model had two domains that each contained only two questions, which is not ideal for face validity. The final domain headings for the Child self-report were derived from the expert card sort survey: ITP Uncertainty; General symptoms; ITP challenges/disruptions; and Loss of control. The four-domain model was also selected for the Parent proxy-report on the basis of the same factors as the Child self-report. Likewise, the four-factor model had higher TLI score and relatively lower root mean square error of approximation (RMSEA) compared to the three-factor. The six-factor model had an ideal RMSEA, but contained one domain that had only two questions. The final domain headings are the same as the Child self-report as the context of the questions are the same. The four-domain model was selected for the Parent impact-report. Though both the four- and six-factor models contained two domains with only two questions each, the two-factor model was not ideal clinically as the questions within each of the two domains were not all similar. The headings were also derived from the expert card-sort: ITP Uncertainty; Treatment; Functional well-being; and Activities. Conclusion The revised KIT 2.0 aims to comprehensively summarize health-related quality of life in pediatric patients with ITP and their parents. The introduction of a domain structure derived from expert- and patient-data to the KIT will enable identification of specific aspects of QOL that are affected, which is imperative given the introduction of novel pharmaceutical agents in ITP treatment.

The association between material-psychological-behavioral framework of financial hardship and markers of inflammation: a cross-sectional study of the Midlife in the United States (MIDUS) Refresher cohort

BackgroundMeasures of financial hardship have been suggested to supplement traditional indicators of socioeconomic status (SES) to elucidate household economic well-being. This study formally tested the construct validity of financial hardship and examined its association with markers of inflammation.MethodsThis study utilized data from the Midlife Development in the United States Refresher Study (MIDUS-R; Age = 23-76, 53.7% female, 71% white). Participants were divided into exploratory factor analysis (EFA; completed SAQs only; N = 2,243) and confirmatory factor analysis sample (CFA; completed SAQs and biomarker assessment; N = 863). Analysis was divided into three steps. First, exploratory factor analysis (EFA) is used to examine if the three-domain factor (material, psychological, and behavioral) is the best fitting model for financial hardship measures. Second, we conducted CFA to test the hypothesized three-factor measurement model of financial hardship. Third, we tested the association between domains and the general latent factor of financial hardship and inflammation (interleukin 6/IL6, c-reactive protein/CRP, and fibrinogen).ResultsResults from EFA supported the three-domain model of financial hardship. The hypothesized three-domain measurement model fits well in a different sample within MIDUS-R. In the models adjusted for age and sex, higher material hardship was associated with elevated IL6, CRP, and fibrinogen, while higher behavioral hardship was associated with higher CRP. The association between the material domain and IL6 remained significant after adding body mass index, education, and race as additional covariates. The second-order financial hardship measurement model was associated with IL6, CRP, and fibrinogen, adjusted for age, sex, BMI, education, and race.ConclusionExplicating the socioeconomic environment to include indicators of financial hardship can help researchers better understand the pathway between SES and the inflammation process, which may help elucidate pathways between SES and age-related chronic diseases associated with inflammation.

Validity and reliability assessment: Nursing Professional Values Scale-Three (NPVS-3) for Brazil

AimTo perform the translation and cross-cultural adaptation of the Nurses Professional Values Scale-Three (NPVS-3) and to verify the psychometric properties of the translated and adapted instrument. MethodsThe study was divided into three stages: (1) cultural and linguistic validation; (2) content and face validity; and (3) construct validity. The translation was performed in stages, including translation, reverse translation, and committee review. The translated scale was applied to 337 nursing students and 123 nurses. The Cronbach coefficient was used to analyze internal consistency and confirmatory factor analysis was performed to assess the construct validity of the three-domain model of the NPVS-3. ResultsThe Cronbach's alpha values for Caring (0.795), Activism (0.882), and Professionalism (0.699) were adequate. The construct validity was confirmed by confirmatory factor analysis, which identified the three-factor model as the original NPVS-3. ConclusionsThe Brazilian version of the NPVS-3 has adequate validity and is effective in assessing the professional values of nurses and nursing students in Brazil.

The impact of perceived social hospitality on destination image: The moderating effect of cultural intelligence

Based on the three-domain model of hospitality, this study examines tourists' perceptions of social hospitality during personal or unplanned, spontaneous interactions with locals. Adopting a mixed-methods design, this study has been conducted in two stages. Exploratory factor analysis in phase 1 (N = 239) supports the three-dimensional structure of social hospitality. In phase 2 (N = 353), structural equation modeling was used to analyze the data, the influence of social hospitality on destination image via emotional solidarity was measured, and the moderating effect of cultural intelligence was investigated. Concurrently, it has been discovered that only 'equally communicating with visitors' in social hospitality has a direct effect on the destination image. The effect of ‘concern for the safety of tourists’ on the destination image must be completely mediated by emotional solidarity. Additionally, it was discovered that cultural intelligence moderates the relationship between social hospitality and emotional solidarity. The implications, both theoretical and practical, have also been discussed.

Impact of the COVID-19 Pandemic on Learning: Assessing Cognitive, Affective, and Psychomotor Skills

The acquisition of cognitive, affective, and psychomotor skills is highly important for successful learning outcomes. This article aims to evaluate the Three-Domain Model (TDM) of learning (cognitive, affective, and psychomotor) during the COVID-19 online classes for tertiary students in Bangladesh. This current study aims at the psychometric evaluation and validation of tertiary students' learning loss during the pandemic. A survey questionnaire is administered using the Likert scale. The components of the questionnaire are based on the Three-Domain Model reflecting the cognitive, affective, and psychomotor skills of the students. The article informs of the learning loss due to the pandemic while suggesting the benefits of online classes. The major finding of the article is that learners lost their skills mainly related to the cognitive domain during the pandemic due to online classes. However, at the same time, their skills related to affective and psychomotor domains increased. Therefore, recommendations for minimizing learning loss are also provided to guide future empirical work in the post-pandemic era.

The Management of Workplace Violence against Healthcare Workers: A Multidisciplinary Team for Total Worker Health® Approach in a Hospital.

The risk of aggression against healthcare workers (HCWs) is a globally well-known topic. However, workplace violence (WV) is often considered as part of HCW’s job, leading to a general underreporting. This cross-sectional study aims at providing a descriptive analysis of aggressive acts against HCWs registered in a 34-month period in a pediatric hospital. According to a specific protocol, each aggressive act was analyzed by a multidisciplinary team using the “Modified Overt Aggression Scale” (MOAS), the “General Health Questionnaire-12” (GHQ-12), and the “Short Form-36 Health Survey” (SF-36) to build a report addressing improvement measures. A three-domain model of WV was also developed considering: (1) assaulted HCWs, (2) attacker-related issues, and (3) environmental context. Contributing factors to overt aggression were outlined and tested using univariate analyses. Statistically significant factors were then included in a multiple linear regression model. A total of 82 aggressive acts were registered in the period. MOAS scores registered a mean value of 3.71 (SD: 4.09). Verbal abuse was the most common form of WV. HCWs professional category, minor psychiatric disorder, emotional role limitation, type of containment used, and emotion intensity were significantly associated with overt aggression (p < 0.05), as well as the attacker’s role in the hospital (p < 0.05). The multiple regression analysis confirmed these findings (p < 0.001). Raising awareness on the aggression risk and contributing factors may lead to a relevant improvement of workplace environment, individual workers’ health, and organizational well-being.

Brazilian Version of the Nursing Professional Values Scale: Validity and Reliability Assessment.

Background and Purpose: The Nurses Professional Values Scale-3 (NPVS-3) is an instrument designed to measure nurses professional values. This study aimed to assess the cultural reliability and validity of the NPVS-3 for use in Brazil. Methods: Translation followed the steps: translation, back-translation, Internal consistency was verified using Cronbach's alpha coefficient and construct validity, by confirmatory factor analysis for the NPVS-3 three-domain model. Results: NPVS-3 applied to 169 nursing students. The culturally and semantically equivalent to the original English version was appropriate. The internal consistency values of each factor represented by Cronbach's alpha were adequate: Care (0.790), Activism (0.898), and Professionalism (0.763). Conclusion: The analyses showed that the Brazilian version of NPVS-3 has high validity and reliability, being effective in assessing professional nursing values for Brazil.

Construct validity of the Suboptimal Health Status Questionnaire-25 in a Ghanaian population

BackgroundThe Suboptimal Health Status Questionnaire-25 (SHS-Q-25) developed to measure Suboptimal Health Status has been used worldwide, but its construct validity has only been tested in the Chinese population. Applying Structural Equation Modelling, we investigate aspects of the construct validity of the SHS-Q-25 to determine the interactions between SHS subscales in a Ghanaian population.MethodsThe study involved healthy Ghanaian participants (n = 263; aged 20–80 years; 63% female), who responded to the SHSQ-25. In an exploratory factor and parallel analysis, the study extracted a new domain structure and compared to the established five-domain structure of SHSQ-25. A confirmatory factor analysis (CFA) was conducted and the fit of the model further discussed. Invariance analysis was carried out to establish the consistency of the instrument across multi-groups.ResultsThe extracted domains were reliable with Cronbach’s alpha of 0.846, 0.820 and 0.864 respectively, for fatigue, immune-cardiovascular and cognitive. The CFA revealed that the model fit indices were excellent left( {{text{RMSEA}} = 0.049~ < ~0.08,,{text{CFI}} = 0.903 > 0.9,,{text{GFI}} = 0.880 < 0.9,,{text{TLI}} = 0.907 > 0.9} right). The fit indices for the three-domain model were statistically superior to the five-domain model. There were, however, issues of insufficient discriminant validity as some average variance extracts were smaller than the corresponding maximum shared variance. The three-domain model was invariant for all constrained aspects of the structural model across age, which is an important risk factor for most chronic diseases.ConclusionThe validity tests suggest that the SHS-Q25 can measure SHS in a Ghanaian population. It can be recommended as a screening tool to early detect chronic diseases especially in developing countries where access to facilities is diminished.

Development of 5 Cs Educational Value Scale for eSport Games

With the growing popularity of eSport games, eSport-related issues have gradually gained attention and discussion in academic research. However, the positive benefits (values) brought by playing eSport have not received too much attention in current research. Therefore, after reviewing related research in the past, this study proposed that eSport has the 5 Cs educational Value of cultivating the cooperative attitude, communication skills, critical thinking, self-confidence and continuous improvement attitude based on the three-domain model (TDM) of cognitive, affective and psychomotor, and developed an eSport educational values scale. In this study, a conceptual sampling method was adopted and players with eSport experience were invited to fill out the questionnaire. A total of 316 participants filled out the questionnaire, 51 invalid samples were deleted, the number of effective participants was 265, and the effective recovery rate was 83.9%. Then SPSS 23.0 and AMOS 20.0 were used to analyze the reliability and validity of the scale, and the verification results show the scale developed by this study has good reliability and validity. In addition, in this study, it was also found that the participants had a positive view (M 3.9) on the 5 Cs educational value of the MOBA type eSport, which shows that eSport is not only a casual game, moderate playing this game can also bring educational significance to players.

An Empirically Derived Three-Domain Model of Binge Eating Behavior

Several factors, identified in various psychological models and theories, have been linked to binge-eating (BE) behaviors. Though commonalities exist between these theories, the main functional domains that contribute to the development and maintenance of these behaviors remain unclear. Here, we applied a data-driven dimension reduction approach to a broad community sample to develop an empirically based model of BE behaviors. We hypothesized that impairments in BE behavior are related to three broad functional domains shown to underlie addictive and impulsive behavior: 1) reward-related processing, 2) negative emotionality and 3) cognitive control.

An Empirically Derived Three-Domain Model of Substance Use Disorder

Current neurobiological theories of addiction are often dual models that propose that impairments in reward/approach related behavior and cognitive control underlie chronic drug use. Some models also suggest involvement of negative emotionality. However, few have evaluated these models empirically across different substance use disorders (SUD). Here, we used a data-driven dimension reduction approach to describe the complete phenotypic space assessed in a large community sample containing 30% individuals with SUD.

Psychometric properties of the critical thinking disposition assessment test amongst medical students in China: a cross-sectional study

BackgroundCritical thinking disposition helps medical students and professionals overcome the effects of personal values and beliefs when exercising clinical judgment. The lack of effective instruments to measure critical thinking disposition in medical students has become an obstacle for training and evaluating students in undergraduate programs in China. The aim of this study was to evaluate the psychometric properties of the CTDA test.MethodsA total of 278 students participated in this study and responded to the CTDA test. Cronbach’s α coefficient, internal consistency, test-retest reliability, floor effects and ceiling effects were measured to assess the reliability of the questionnaire. Construct validity of the pre-specified three-domain structure of the CTDA was evaluated by explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). The convergent validity and discriminant validity were also analyzed.ResultsCronbach’s alpha coefficient for the entire questionnaire was calculated to be 0.92, all of the domains showed acceptable internal consistency (0.81–0.86), and the test-retest reliability indicated acceptable intra-class correlation coefficients (ICCs) (0.93, p < 0.01). The EFA and the CFA demonstrated that the three-domain model fitted the data adequately. The test showed satisfactory convergent and discriminant validity.ConclusionsThe CTDA is a reliable and valid questionnaire to evaluate the disposition of medical students towards critical thinking in China and can reasonably be applied in critical thinking programs and medical education research.

Effect of moisture in κ-carrageenan films on their tensile and relaxation behavior studied by correlation between stress and birefringence

A picture on the molecular level describing the deformation and the following relaxation of κ-carrageenan chains has been proposed based on the three-domain structural model for κ-carrageenan films and on the idea of the modified stress-optical rule. The uniaxial tensile and the relaxation behavior for dry and moist κ-carrageenan films has been examined by using a homemade apparatus available for the simultaneous mechanical and birefringence measurements. It has been suggested that the continuous amorphous phase of κ-carrageenan in the dry film is deformed together with the local glass component, and only the glass component relaxes in the following process. On the other hand, concerning the moist film, the crosslinks of κ-carrageenan aggregates in addition to the continuous phase are movable with deformation, while the following relaxation is attributed only to the unbridged κ-carrageenan chains in the continuous phase.

Measuring Mindsets and Achievement Goal Motivation: A Validation Study of Three Instruments.

To evaluate the validity of scores from three instruments measuring achievement goal motivation-related constructs: a shortened version of Dweck's Implicit Theories of Intelligence Scale (ITIS-S), measuring incremental and entity mindsets; Elliot's Achievement Goal Questionnaire-Revised (AGQ-R), measuring mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance achievement goals; and Midgley's Patterns of Adaptive Learning Scales (PALS), measuring mastery, performance-approach, and performance-avoidance achievement goals. High school students participating in a medical simulation training activity in May 2017 completed each instrument. The authors evaluated internal structure using reliability and factor analysis and relations with other variables using the multitrait-multimethod matrix. There were 178 participants. Internal consistency reliability (Cronbach alpha) was > 0.70 for all subscores. Confirmatory factor analysis of ITIS-S scores demonstrated good model fit. Confirmatory factor analysis of AGQ-R scores demonstrated borderline fit; exploratory factor analysis suggested a three-domain model (approach, mastery-avoidance, performance-avoidance). Confirmatory factor analysis of PALS scores also demonstrated borderline fit; exploratory factor analyses suggested consistent distinction between mastery and performance goals but inconsistent distinction between performance-approach and performance-avoidance goals. Correlations among AGQ-R and PALS scores were large for mastery (r = 0.72) and moderate for performance (≥ 0.45) domains; correlations among incremental and mastery scores were moderate (≥ 0.34). Contrary to expectations, correlations between entity and performance scores were negligible. Correlations between conceptually unrelated domains were small or negligible. All instrument scores had good internal consistency and generally appropriate relations with other variables, but empirically determined domain structures did not consistently match theory.

Three-Domain Model for Disaster Management Framework

Existing bodies of research on disaster management frameworks have not been always satisfactorily explained all aspects of catastrophe due to their inadequate applications. This article provides a comprehensive framework, which is a three-domain model, for the goal of mitigating various disasters. Qualitative content analysis has been used as a methodology, while studying flexible organizational management. This model considers disaster, human behavior, and disaster environment as three domains. Human behavioral factors are safety needs, forgetfulness, incentive scheme, disaster mitigation, and enabling sustainability. The model also takes into account all variables in the field, not only the positive aspects, but also the negative aspects of disaster management. The major finding is that, if appropriate, the model may be cognitively utilized as a multi-purpose model as well as a theoretical criterion for the international community.

Measuring achievement goal motivation, mindsets and cognitive load: validation of three instruments' scores.

Measurement of motivation and cognitive load has potential value in health professions education. Our objective was to evaluate the validity of scores from Dweck's Implicit Theories of Intelligence Scale (ITIS), Elliot's Achievement Goal Questionnaire-Revised (AGQ-R) and Leppink's cognitive load index (CLI). This was a validity study evaluating internal structure using reliability and factor analysis, and relationships with other variables using the multitrait-multimethod matrix. Two hundred and thirty-two secondary school students participated in a medical simulation-based training activity at an academic medical center. Pre-activity ITIS (implicit theory [mindset] domains: incremental, entity) andAGQ-R (achievement goal domains: mastery-approach, mastery-avoidance, performance-approach, performance-avoidance), post-activity CLI (cognitive load domains: intrinsic, extrinsic, germane) and task persistence (self-directed repetitions on a laparoscopic surgery task) were measured. Internal consistency reliability (Cronbach's alpha) was > 0.70 for all domain scores except AGQ-R performance-avoidance (alpha 0.68) and CLI extrinsic load (alpha 0.64). Confirmatory factor analysis of ITIS and CLI scores demonstrated acceptable model fit. Confirmatory factor analysis of AGQ-R scores demonstrated borderline fit, and exploratory factor analysis suggested a three-domain model for achievement goals (mastery-approach, performance and avoidance). Correlations among scores from conceptually-related domains generally aligned with expectations, as follows: ITIS incremental and entity, r=-0.52; AGQ-R mastery-avoidance and performance-avoidance, r=0.71; mastery-approach and performance-approach, r=0.55; performance-approach and performance-avoidance, r=0.43; mastery-approach and mastery-avoidance, r=0.36; CLI germane and extrinsic, r=-0.35; ITIS incremental and AGQ-R mastery-approach, r=0.34; ITIS incremental and CLI germane, r=0.44; AGQ-R mastery-approach and CLI germane, r=0.48 (all p<0.001). We found no correlation between the number of task repetitions (i.e. persistence) and mastery-approach scores, r=-0.01. ITIS and CLI scores had appropriate internal structures and relationships with other variables. AGQ-R scores fit a three-factor (not four-factor) model that collapsed avoidance into one domain, although relationships of other variables with the original four domain scores generally aligned with expectations. Mastery goals are positively correlated with germane cognitive load.

Diffusion and reaction pathways of water near fully hydrated TiO2 surfaces from ab initio molecular dynamics.

Ab initio molecular dynamics simulations are reported for water-embedded TiO2 surfaces to determine the diffusive and reactive behavior at full hydration. A three-domain model is developed for six surfaces [rutile (110), (100), and (001), and anatase (101), (100), and (001)] which describes waters as "hard" (irreversibly bound to the surface), "soft" (with reduced mobility but orientation freedom near the surface), or "bulk." The model explains previous experimental data and provides a detailed picture of water diffusion near TiO2 surfaces. Water reactivity is analyzed with a graph-theoretic approach that reveals a number of reaction pathways on TiO2 which occur at full hydration, in addition to direct water splitting. Hydronium (H3O+) is identified to be a key intermediate state, which facilitates water dissociation by proton hopping between intact and dissociated waters near the surfaces. These discoveries significantly improve the understanding of nanoscale water dynamics and reactivity at TiO2 interfaces under ambient conditions.

The Sexual Violence Risk-20: factor structure and psychometric properties

Although the Sexual Violence Risk-20 (SVR-20) is widely used, its psychometric properties have only been investigated in a limited number of studies. This study explored the factor structure of the SVR-20 and examined its psychometric properties. Confirmatory factor analysis (CFA) was used to examine the fit of the original three-domain model of the SVR-20. The CFA showed that the original structure was not satisfactory. Exploratory principal components analysis (PCA) was conducted in search of a more optimal factor structure. Psychometric properties (i.e., internal consistency, predictive value, and convergent validity) of both the original domains and alternative factors were investigated. The PCA and subsequent CFAs pointed in the direction of an alternative, more optimal three-factor solution. The three alternative factors were labeled as Antisociality, Sexual deviance, and Problematic thinking and produced better internal consistency coefficients than the original domains. However, the validity of the SVR-20 was modest and no evidence was found indicating that the alternative factors were better in this regard as compared to the original domains. Despite the overall superiority of actuarial measures in predicting recidivism, the structured professional judgment of the SVR-20 proved to be more predictive of sexual, violent, and general recidivism than its actuarial scoring method.
