OBJECTIVE: Existing systematic reviews related to advance care planning (ACP) largely focus on specific groups and intervention efficacy or are limited to contextual factors. This research aims to identify the modifiable factors perceived by different users of ACP in healthcare settings and inform healthcare professionals about the factors affecting ACP practice.
METHODS: Five English-language databases (ProQuest, PubMed, CINAHL Plus, Scopus, and Medline) and two Chinese-language databases (CNKI and NCL) were searched up to November 2022. Empirical research identifying factors related to ACP in healthcare settings was included. ACP is defined as a discussion process on future end-of-life care. Thematic synthesis was performed on all included studies.
RESULTS: A total of 1871 unique articles were screened; the full texts of 193 were assessed by 4 reviewers, and 45 articles were included for analysis. Twenty-two (54%) studies were qualitative, 15 (33%) were quantitative, and 6 (13%) used mixed methods. Foci varied from 28 (62%) studies on a single subject group (either patient, family, or physician), 11 (25%) on 2 subject groups (either patient and family or patient and healthcare professional), and 6 (13%) covered 3 subject groups (patient, family, and healthcare professional). Among the 17 studies involving more than 1 subject group, only 2 adopted a dyadic lens in analysis. Complex interwoven factors were categorized into (1) intrapersonal factors, (2) interpersonal factors, and (3) socio-environmental factors, with a total of 11 themes: personal belief, emotions, the burden on others, timing, responsiveness, relationship, family dynamics, experience, person taking the lead, culture, and support.
CONCLUSIONS: Patients, families, and healthcare professionals are the essential stakeholders of ACP in healthcare settings. Factors are interweaved among the intrapersonal, interpersonal, and socio-environmental dimensions. Research is warranted to examine the dynamic interactions of the 3 essential stakeholders from a multidimensional perspective, and the mechanism of the interweaving of factors.

Disorganised speech, or, formal thought disorder (FTD), is considered one of the core features of psychosis, yet its factor structure remains debated. This systematic review aimed to identify the core dimensions of FTD. In line with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA), a systematic review was conducted on the FTD factor analytic literature. Sixteen studies were identified from PsycINFO, PubMed and Web of Science between October 1971 and January 2023. Across the 39 factor analyses investigated, findings demonstrated the prominence of a three-factor structure. Broad agreement was found for two factors within the three-factor model, which were typically referred to as disorganisation and negative, with the exact nature of the third dimension requiring further clarification. The quality assessment revealed some methodological challenges relating to the assessment of FTD and conducted factor analyses. Future research should clarify the exact nature of the third dimension across different patient groups and methodologies to determine whether a consistent transdiagnostic concept of FTD can be elucidated.

Although a posteriori dietary patterns (DPs) naturally reflect actual dietary behavior in a population, their specificity limits generalizability. Among other issues, the absence of a standardized approach to analysis have further hindered discovery of genuinely reproducible DPs across studies from the same/similar populations. A systematic review on a posteriori DPs from principal component analysis or exploratory factor analysis (EFA) across study populations from Italy provides the basis to explore assessment and drivers of DP reproducibility in a case study of epidemiological interest. First to our knowledge, we carried out a qualitative (i.e., similarity plots built on text descriptions) and quantitative (i.e., congruence coefficients, CCs) assessment of DP reproducibility. The 52 selected articles were published in 2001-2022 and represented dietary habits in 1965-2022 from 70% of the Italian regions; children/adolescents, pregnancy/breastfeeding women, and elderly were considered in 15 articles. The included studies mainly derived EFA-based DPs on food groups from food frequency questionnaires and were of \"good quality\" according to standard scales. Based on text descriptions, the 186 identified DPs were collapsed into 113 (69 food-based and 44 nutrient-based) apparently different DPs (39.3% reduction), later summarized along with the 3 \"Mixed-Salad/Vegetable-based Patterns,\" \"Pasta-and-Meat-oriented/Starchy Patterns,\" and \"Dairy Products\" and \"Sweets/Animal-based Patterns\" groups, by matching similar food-based and nutrient-based groups of collapsed DPs. Based on CCs (215 CCs, 68 DPs, 18 articles using the same input lists), all pairs of DPs showing the same/similar names were at least \"fairly similar\" and ∼81% were \"equivalent.\" The 30 \"equivalent\" DPs ended up into 6 genuinely different DPs (80% reduction) that targeted fruits and (raw) vegetables, pasta and meat combined, and cheese and deli meats. Such reduction reflects the same study design, list of input variables, and DP identification method followed across articles from the same groups. This review was registered at PROSPERO as CRD42022341037.

UNASSIGNED: A psychological condition known as NOMOPHOBIA causes individuals to fear losing ability to use or reach their mobile phones. The NMP-Q (nomophobia questionnaire) is a commonly used survey for assessing symptoms related to nomophobia.
UNASSIGNED: We performed a meta-analysis using reliability generalization (RG) on the NMP-Q. Thirteen studies involving 15,929 participants have reported original reliability estimates of the NMP-Q determined through a comprehensive and methodical examination of the available literature.
UNASSIGNED: For the total scores, the pooled internal consistency reliability was 0.93 [0.91; 0.95] and for the subscales it ranged from 0.83 to 0.91. Specifically, 0.91 [0.88; 0.93], 0.84 [0.80; 0.88], 0.83 [0.78; 0.88, and 0.83 [0.80; 0.85] for the subscales. Subscale 1 = not being able to communicate; subscale 2 = losing connectedness; subscale 3 = not being able to access information; and subscale 4 = giving up convenience\", respectively. All reported effect sizes are Cronbach\'s alphas. Structural validity supported a solution of four-factors.
UNASSIGNED: NMP-Q has an excellent internal consistency. Structural validity of four factors appears to be vigorous in fitting NMP-Q items. Our recommendation is to require future studies using NMP-Q to provide a reliability estimate based on their own data.

Information Security Awareness (ISA) is a significant concept that got considerable attention recently and can assist in minimizing the risks associated with information security breaches. Several measurement scales have been developed in this regard, as measuring users\' ISA is paramount. Although ISA specific scales are very important, yet what methodological rigor they use in terms of initial conceptualization of ISA, data collection and analysis during the development, and scale validation of such scales are some unknown aspects. Therefore, we provide a comprehensive review of the existing ISA specific scales to address all the above concerns. A popular method, PRISMA, is utilized, and a total of 24 articles that match with criteria of this research are included for the final in-depth analysis. Also, a holistic evaluation framework is developed containing three phases and 19 criteria. Findings revealed that most studies treat ISA as a multi-dimensional construct, and ISA researchers rarely conduct both pilot testing and pre-text evaluation while validating and refining the initial scales. Additionally, several articles did not report some of the essential elements used for checking the rigor of factor analysis, and evidence for validities of the identified scales is inadequate. Consequently, existing ISA specific scales must be improved both in terms of the methodological thoroughness of the scale development procedure and their validities. Moreover, not only justifying why the development of a new scale is necessary, but also improving the quality of the existing scales by doing multiple iterations is significant in the future. Likewise, the inclusion of all the dimensions of ISA, while generating the initial items pool is an important aspect to be considered. A thorough discussion, recommendations for future research, conclusions, and study limitations are provided.

Multivariate behavioral research often focuses on latent constructs-such as motivation, self-concept, or wellbeing-that cannot be directly observed. Typically, these latent constructs are measured with items in standardized instruments. To test the factorial structure and multidimensionality of latent constructs in educational and psychological research, Morin et al. (2016a) proposed bifactor exploratory structural equation modeling (B-ESEM). This meta-analytic review (158 studies, k = 308, N = 778,624) aimed to estimate the extent to which B-ESEM model fit differs from other model representations, including confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), hierarchical CFA, hierarchical ESEM, and bifactor-CFA. The study domains included learning and instruction, motivation and emotion, self and identity, depression and wellbeing, and interpersonal relations. The meta-analyzed fit indices were the χ2 /df ratio, the comparative fit index (CFI), the Tucker-Lewis index (TLI), the root mean square error of approximation (RMSEA), and the standardized root mean squared residual (SRMR). The findings of this meta-analytic review indicate that the B-ESEM model fit is superior to the fit of reference models. Furthermore, the results suggest that model fit is sensitive to sample size, item number, and the number of specific and general factors in a model.

Understanding people\'s travel behavior is necessary for achieving goals such as increased bicycling and walking, decreased traffic congestion, and adoption of clean-fuel vehicles. To understand underlying motivations, researchers increasingly are adding subjective variables to models of travel behavior. This article presents a systematic review of 158 such studies. Nearly every reviewed article finds subjective variables to be predictive of transport outcomes. However, the 158 reviewed studies include 2864 distinct subjective survey questions. This heterogeneity makes it difficult to reach definitive conclusions about which subjective variables are most important for which transport outcomes. In addition to heterogeneity, challenges of this literature also include an unclear direction of causality and tautological relationships between some subjective variables and behavior. Within the constraints imposed by these challenges, we attempt to evaluate the explanatory power of subjective variables, which subjective variables matter most for which transport choices, and whether the answers to these questions vary between continents. To reduce heterogeneity in future studies, we introduce the Standardized Transport Attitude Measurement Protocol, which identifies a curated set of subjective questions. We have also developed an open-access database of the reviewed studies, including all subjective survey questions and models, with an interactive, searchable interface.

The purpose of this systematic review is to examine the relationship between dietary patterns and sarcopenia using a protocol developed for use by the 2020 Dietary Guidelines Advisory Committee, and to conduct a meta-analysis to summarize the evidence. Multiple electronic databases were searched for studies investigating sarcopenia risk factors or risk of sarcopenia and dietary patterns. Eligible studies were 1) peer-reviewed controlled trials or observational trials, 2) involving adult or older-adult human subjects who were healthy and/or at risk for chronic disease, 3) comparing the effect of consumption or adherence to dietary patterns (measured as an index/score, factor or cluster analysis; reduced rank regression; or a macronutrient distribution), and 4) reported on measures of skeletal muscle mass, muscle strength, muscle performance, and/or risk of sarcopenia. Thirty-eight publications met all inclusion criteria for qualitative synthesis. Thirteen observational studies met inclusion criteria for meta-analysis. Higher adherence to a healthy dietary pattern was associated with a decreased risk of gait speed reduction (OR = 0.58; 95% CI: 0.18, 0.97). The association between healthy dietary pattern adherence and other intermediate markers or risk of sarcopenia was not statistically significant. The majority of individual studies were judged as \"serious\" risk of bias and analysis of the collective evidence base was suggestive of publication bias. Studies suggest a significant association between healthy dietary patterns and maintenance of gait speed with age, an intermediate marker of sarcopenia risk, but the evidence base is limited by serious risk of bias, within and between studies. Further research is needed to understand the association between healthy dietary patterns and risk of sarcopenia.

The main aim was to perform a systematic literature review of studies investigating the factor structure of the Eating Disorder Examination-Questionnaire (EDE-Q), a widely used measure of eating pathology. Secondary aims were to summarize the quality of reporting of latent variable (factor) analyses in these studies and review support for different factor solutions.
Literature was identified through Scopus, Medline, PsycInfo, and ProQuest databases published up to February 23, 2022 and outreach via an international listserv. All studies published in English reporting factor analysis of the EDE-Q were included with few restrictions. Sixty studies including 63,389 participants met inclusion criteria.
The originally proposed four-factor solution received little empirical support, although few alternative models have been robustly evaluated. Items assessing shape and weight concerns frequently coalesce in factor solutions, suggesting that these constructs are closely related. Investigations of brief versions of the EDE-Q have produced more consistent findings, suggesting that these measures, particularly a seven-item version, might be useful alternatives to the full version. Quality of studies was reasonable, with important methodological elements of factor analysis often reported.
The findings are of relevance to practitioners and researchers, suggesting that the \"original\" factor structure of the EDE-Q should be reconsidered and that use of a seven-item version is to be encouraged.
Self-report questionnaires are widely used in the assessment of disordered eating. The current study found that there is little consensus about the structure of a common measure of eating psychopathology. There is more consistent support for a brief, seven-item, version assessing dietary restraint, body dissatisfaction, and overvaluation of weight and shape.
El objetivo principal fue realizar una revisión sistemática de la literatura de los estudios que investigan la estructura factorial del Cuestionario de Eating Disorders Examination (EDE-Q), una medida ampliamente utilizada en la patología alimentaria. Los objetivos secundarios fueron resumir la calidad del informe de los análisis de variables latentes (factores) en estos estudios y revisar el apoyo a diferentes soluciones factoriales. MÉTODO: La literatura se identificó a través de las bases de datos Scopus, Medline, PsycInfo y ProQuest publicadas hasta el 23 de febrero de 2022 y de divulgación a través de un servidor de listas internacional. Todos los estudios publicados en inglés que reportaron el análisis factorial de la EDE-Q se incluyeron con pocas restricciones. Sesenta estudios con 63,389 participantes cumplieron los criterios de inclusión.
La solución de cuatro factores propuesta originalmente recibió poco apoyo empírico, aunque pocos modelos alternativos han sido evaluados sólidamente. Los elementos que evalúan las preocupaciones de peso y figura corporal con frecuencia se unen en soluciones factoriales, lo que sugiere que estos constructos están estrechamente relacionados. Las investigaciones de versiones breves del EDE-Q han producido conclusiones más consistentes, lo que sugiere que estas mediciones, en particular una versión de siete ítems, podrían ser alternativas útiles a la versión completa. La calidad de los estudios fue razonable, y a menudo se reportaron elementos metodológicos importantes del análisis factorial. DISCUSIÓN: Los hallazgos son relevantes para los clínicos e investigadores, lo que sugiere que la estructura factorial “original” del EDE-Q debe reconsiderarse y que se debe alentar el uso de una versión de siete ítems.

Background: Many phenotypic studies have estimated the degree of comorbidity between Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD), but few have examined the latent, or unobserved, structure of combined ASD and ADHD symptoms. This is an important perquisite toward better understanding the overlap between ASD and ADHD. Methods: We conducted a scoping review of studies that examined the factor or latent class structure of ASD and ADHD symptoms within the same clinical or general population sample. Results: Eight studies met final inclusion criteria. Four factor analysis studies found that ASD and ADHD domains loaded separately and one found that some ASD and ADHD domains loaded together. In the three latent class studies, there were evidence of profiles with high levels of co-occurring ASD and ADHD symptoms. Conclusions: Our scoping review provides some evidence of phenotypic overlap between ASD and ADHD at the latent, or unobserved, level, particularly when using a \"person-centered\" (latent class analysis) vs. a \"variable-centered\" (factor analysis) approach.
