The Broad Autism Phenotype-International Test (BAP-IT): A two-domain-based test for the assessment of the broad autism phenotype.

LAY ABSTRACT: The broad autism phenotype refers to a group of behaviors related to autism spectrum disorder, but that appear to a lesser extent. Its assessment has been performed through outdated broad autism phenotype/autism spectrum disorder definitions and tests. To address this problem, this study presents the development of a new test, the Broad Autism Phenotype-International Test, a 20-item measure consisting of two dimensions, SOCIAL-BAP and RIRE-BAP, targeting the two-domain operationalization of autism spectrum disorder in Spain and the United Kingdom. Unlike the Broad Autism Phenotype Questionnaire, this test received empirical support as a quick and effective broad autism phenotype measure that can facilitate both broad autism phenotype/autism spectrum disorder research and interventions. This is the first step to studying the BAP in several Spanish and English-speaking countries.

A compendium of evidence-based practice instruments for nursing education, practice and research.

BACKGROUND: Evidence-based practice (EBP) is a cornerstone for safe, high-quality care. Implementation science recognizes that many factors influence the successful use of EBP, from attitudes and beliefs, self-efficacy, and knowledge and skills to contextual factors related to unit and organizational culture. This integrative review aimed to identify valid and reliable instruments measuring critical EBP domains with nursing professionals. METHODS: A systematic search of the literature was conducted. CINAHL, PubMed, EMBASE, Cochrane, and Joanna Briggs were searched to identify original research publications testing the reliability and validity of EBP nursing instruments. RESULTS: Of 347 records, 48 studies representing 50 instruments were identified as having undergone psychometric testing, thus meeting the inclusion criteria. Most instruments were validated in English-speaking countries. Content validity, construct validity, and internal consistency standards were met for 70%, 62%, and 94% of instruments, respectively. Limited testing was found for other types of validity, test-retest reliability, acceptability, feasibility, or responsivity and sensitivity, thus representing gaps in psychometric validation. Less than 20% of instruments have been translated to other languages limiting their use to advance EBP worldwide. LINKING EVIDENCE TO ACTION: Eighty-two percent of instruments met minimal psychometric standards and are sound for education, practice, and research. Expanding psychometric testing and utilizing validated EBP instruments will further the EBP movement to improve global population health.

Cross-cultural Diagnostic Validity of the Multilingual Naming Test (MINT) in a Sample of Older Adults.

OBJECTIVE: We aimed to evaluate the psychometric properties and diagnostic accuracy of the 32-item version of the Multilingual Naming Test (MINT) in participants from 2 ethnic groups (European Americans [EA; n = 106] and Hispanic Americans [HA; n = 175]) with 3 diagnostic groups (cognitively normal [CN], n = 94, mild cognitive impairment [MCI], n = 148, and dementia, n = 39). METHOD: An Item Response Theory model was used to evaluate items across ethnicity and language groups (Spanish and English), resulting in a 24-item version. We analyzed the MINT discriminant and predictive validity across diagnostic groups. RESULTS: A total of 8 items were differentially difficult between languages in the 32-item version of the MINT. EA scored significantly higher than HA, but the difference was not significant when removing those 8 items (controlling for Education). The Receiver Operating Characteristics showed that the MINT had poor accuracy when identifying CN participants and was acceptable in identifying dementia participants but unacceptable in classifying MCI participants. Finally, we tested the association between MINT scores and magnetic resonance imaging volumetric measures of language-related areas in the temporal and frontal lobes. The 32-item MINT in English and Spanish and the 24-item MINT in Spanish were significantly correlated with the bilateral middle temporal gyrus. The left fusiform gyrus correlated with MINT scores regardless of language and MINT version. We also found differential correlations depending on the language of administration. CONCLUSIONS: Our results highlight the importance of analyzing cross-cultural samples when implementing clinical neuropsychological tests such as the MINT.

A tutorial on automatic post-stratification and weighting in conventional and regression-based norming of psychometric tests.

Norm scores are an essential source of information in individual diagnostics. Given the scope of the decisions this information may entail, establishing high-quality, representative norms is of tremendous importance in test construction. Representativeness is difficult to establish, though, especially with limited resources and when multiple stratification variables and their joint probabilities come into play. Sample stratification requires knowing which stratum an individual belongs to prior to data collection, but the required variables for the individual's classification, such as socio-economic status or demographic characteristics, are often collected within the survey or test data. Therefore, post-stratification techniques, like iterative proportional fitting (= raking), aim at simulating representativeness of normative samples and can thus enhance the overall quality of the norm scores. This tutorial describes the application of raking to normative samples, the calculation of weights, the application of these weights in percentile estimation, and the retrieval of continuous, regression-based norm models with the cNORM package on the R platform. We demonstrate this procedure using a large, non-representative dataset of vocabulary development in childhood and adolescence (N = 4542), using sex and ethnical background as stratification variables.

Ecological validity of the Meyers Neuropsychological Battery.

Neuropsychologists are increasingly being asked to apply neuropsychological test results to real world functioning; however, neuropsychological tests are not usually constructed to do so, but instead are more concerned with diagnostic accuracy than with prediction of daily functioning. Using samples of 5,460 patients that did self-ratings and 2791 patients that had family ratings plus the Meyers Neuropsychological Battery (MNB), it was found that the family ratings were better predicted by neuropsychological test data than were self-ratings on the 38 item Patient Competency Rating Scale (PCRS). The R values for family ratings on the 36 regression equations ranged from .236 to .763. The results show that the ratings given patients by family members could be predicted by the neuropsychological test results. These findings can help the clinician to make broad statements regarding likely real-life functioning and also support the ecological validity of the tests that make up the MNB.

Establishing the Test-Retest Reliability and Minimal Detectable Change of the Multiple Sclerosis Resiliency Scale.

BACKGROUND: The Multiple Sclerosis Resiliency Scale (MSRS) was designed to assess factors connected to resilience when facing MS-related challenges. Although the MSRS has demonstrated good internal consistency and construct validity, its test-retest reliability has yet to be established. Identifying the minimal detectable change (MDC) of the scale will also improve its utility as an outcome measure for resilience-based interventions. This study aimed to determine the test-retest reliability and MDC of the MSRS. METHODS: Participants were 62 persons with MS who completed the MSRS twice, with a mean ± SD of 16.60 ± 3.97 days (range, 14-30 days) between assessments. Test-retest reliability was evaluated using a 2-way, random-effects, single-measurement intraclass correlation coefficient (ICC), with agreement between time 1 and time 2 visualized with a Bland-Altman plot. The MDC was calculated using the standard error of measurement with a 95% CI. RESULTS: At time 1, the mean ± SD MSRS score was 77.19 ± 11.97 (range, 45.83-97.00); at time 2, the mean ± SD score was 76.38 ± 12.75 (range, 46-98). The MSRS total score had good test-retest reliability (ICC = 0.88), with the subscale ICCs ranging from 0.77 (MS Peer Support) to 0.93 (Spirituality). The MDC for the total score was 11.95. CONCLUSIONS: These findings suggest that the MSRS has good test-retest reliability and that persons with MS with a difference of 12 points or more between assessments have experienced a reliable change. The results support the utility of the MSRS as a potential outcome measure for MS-related resilience.

Validation of and Normative Data of the DVAQ-30, a New Video-Naming Test for Assessing Verb Anomia.

OBJECTIVE: Anomia is usually assessed using picture-naming tests. While many tests evaluate anomia for nouns, very few tests have been specifically designed for verb anomia. This article presents the DVAQ-30, a new naming test for detecting verb anomia in adults and elderly people. METHOD: The article describes three studies. Study 1 focused on the DVAQ-30 development phase. In Study 2, healthy participants and individuals with post-stroke aphasia, mild cognitive impairment, Alzheimer's disease, or primary progressive aphasia were assessed using the DVAQ-30 to establish its convergent and discriminant validity, test-retest reliability, and internal consistency. In Study 3, a group of adults and elderly Quebec French-speaking adults were assessed to obtain normative data. RESULTS: The DVAQ-30 had good convergent validity and distinguished the performance of healthy participants from that of participants with pathological conditions. The test also had good internal consistency, and the test-retest analysis showed that the scores had good temporal stability. Furthermore, normative data were collected on the performance of 244 participants aged 50 years old and over. CONCLUSIONS: The DVAQ-30 fills an important gap and has the potential to help clinicians and researchers better detect verb anomia associated with pathological aging and post-stroke aphasia.

The Continuous Matching Task (CMT) - real-time procedural stimulus generation for adaptive testing of attention.

The Continuous Matching Task (CMT) is a novel paradigm designed to measure sustained attention and alertness. It is a special type of Continuous Performance Task (CPT) that utilizes truly continuous stimulus material. Stimuli are generated in real-time by a procedural algorithm which also enables adaptive testing. The task is highly flexible and can be used in either single or dual-task configurations that also allow for task mixing. The functionality of the algorithm and applications are presented. The viability of the CMT is tested and results are compared with similar tasks, i.e. Stroop-Task and Conner's CPT (CCPT), as well as self-reports of ADHD in adults in a Multi-Trait-Multi-Method approach in a sample of N = 122 participants. Self-reports and measurements of heart rate variability during testing are analyzed to infer and compare mental workload during tasks. Overall, variants of the CMT induce a higher mental workload than the other tasks, and employing the dual-task CMT with adaptive difficulty resulted in the highest reliability and validity. Results indicate that the CMT is primarily a measure of alertness and processing speed and benefits from adaptive testing.

Normative Reference Values for Crystallized-Fluid Discrepancy Scores for the NIH Toolbox Cognition Battery.

INTRODUCTION: The purpose of this study was to translate NIH Toolbox Cognition Battery (NIHTB-CB) Crystallized-Fluid discrepancy scores into research and clinical practice with adults by providing normative data for discrepancy scores for both age-adjusted standard scores (SSs) and demographically adjusted T-scores. METHOD: We included adult participants from the NIHTB-CB standardization sample who denied having neurodevelopmental, medical, psychiatric, or neurological conditions (n = 730; M = 47.4 years old, SD = 17.6, range: 18-85; 64.4% women; 63.1% White). Descriptive statistics were calculated for the Fluid and Crystallized composite scores and Crystallized-Fluid discrepancy score, along with correlations between the composite scores and reliability estimates of the discrepancy score. Percentiles were calculated for the discrepancy score, with stratifications by the gender, education, and Crystallized composite for the age-adjusted SSs and demographically adjusted T-scores (T). RESULTS: Crystallized-Fluid discrepancy scores ranged from -40 to 44 (M = -0.63, SD = 14.89, Mdn = -1, interquartile range [IQR]: -11 to 10) for age-adjusted SSs and from -29 to 27 (M = -0.39, SD = 10.49, Mdn = -1, IQR = -8 to 7) for demographically adjusted T-scores. Crystallized-Fluid discrepancy scores of SS = 15 and T = 11 were at the 16th percentile (1 SD below the mean) and discrepancy scores of SS = 21 and T = 15 were at the 7th percentile (1.5 SD below the mean). CONCLUSIONS: Crystallized-Fluid discrepancy scores may be, with future research, a useful within-person interpretive approach for detecting a decline from pre-injury or pre-disease levels of cognitive functioning. These normative reference values assist clinicians and researchers in determining the frequency at which given Crystallized-Fluid discrepancy scores occurred among healthy adults in the normative sample.

The Test of Visuospatial Construction: A Novel Test of Non-motoric Visuoconstruction.

OBJECTIVE: The Test of Visuospatial Construction (TVSC) was designed as an easily administered measure of non-motor visuoconstruction, though only preliminary data exists regarding the clinical utility of this task. The current study examined the diagnostic accuracy of the TVSC by comparing performance between healthy subjects and various clinical groups. The authors also wanted to determine whether previous findings could be replicated regarding its effectiveness at tracking cognitive decline. METHOD: Archival data collected over a period of more than 10 years were utilized and the overall sample consisted of 955 individuals, 372 healthy subjects, and 583 subjects who were categorized into various clinical groups. Only TVSC test data and demographic variables were utilized for statistical analyses in this study. RESULTS: The control group obtained significantly higher scores on the TVSC than the clinical groups. AUC values were indicative of excellent discrimination between cases and controls. Exploratory ROC curve analyses suggested adequate to excellent discrimination between the control group and the individual clinical groups as well as between the mild cognitive impairment (MCI) subgroups and the two dementia groups. CONCLUSIONS: This study demonstrates that the TVSC can effectively differentiate between healthy subjects and neurologically compromised individuals. Additionally, the TVSC may be able to measure the progressive decline in visuoconstructive abilities that occurs as patients traverse the spectrum of MCI and dementia.

Cognitive Interview in the Search for Validity Evidence Based on Response Processes / Entrevistas Cognitivas na Busca de Evidências de Validade Baseadas no Processo de Resposta / Entrevistas Cognitivas en la Búsqueda de Evidencia de Validez Basada en el Proceso de Respuesta

Abstract Cognitive interviews can provide validity evidence for instruments based on item response processes; however, use of focus groups still prevails in Brazilian literature. Moreover, semantic analysis has only been considered when searching for validity evidence based on test content. This paper presents a proposal for qualitative data analysis based on cognitive interviewing, thus providing researchers with a protocol that enables best practices in carrying out this technique, and consolidating it in the Brazilian literature as an option to search for validity evidence based on item response processes. To conclude, we present some criticisms regarding current procedures for validity evidence based on test content and discuss some possibilities.

Sistema de avaliação de testes psicológicos: histórias contadas e não contadas / Psychological test evaluation system: stories told and untold / Sistema de evaluación de tests psicológicos: historias contadas y no contadas

O Sistema de Avaliação de Testes Psicológicos (SATEPSI) recebeu notoriedade entre brasileiros e estrangeiros por oferecer um complexo sistema de qualificação dos testes psicológicos, pouco visto em âmbito mundial. Sua elaboração dependeu de uma autarquia, que o financiou, normatizou e o mantém, mas também de pesquisadores docentes de avaliação psicológica, que trouxeram a expertise da área para que houvesse o pleno estabelecimento de seus parâmetros. Passadas duas décadas de seu lançamento, o SATEPSI foi tema de artigos, capítulos, lives e diálogos digitais, nos quais foram destaque, de modo geral, as Resoluções do Conselho Federal de Psicologia, que o normatiza, e seus impactos para a área de avaliação psicológica - como, por exemplo, o aumento do número de pesquisas e de testes brasileiros qualificados. O que se pretende neste artigo é mencionar sua construção, à luz dos autores que vivenciaram o SATEPSI em funções e tempos distintos. Atenção especial será dada aos Métodos Projetivos, cuja história ainda é pouco revelada.(AU)

The system to evaluate psychological tests (Satepsi) received notoriety among Brazilians and foreigners for offering a complex system of qualification of psychological tests, which is rarely seen worldwide. Its development depended on an autarchy (which financed, standardized, and maintains it) and on researchers teaching psychological assessment, who brought their expertise to the area so its parameters could be fully established. After two decades of its launch, Satepsi was the subject of articles, chapters, lives, and digital dialogues, which usually highlighted the Resolutions of the Federal Council of Psychology that normatize psychological evaluation and their impacts, such as the increase in the number of qualified Brazilian tests. This study aims to mention its construction in the light of the authors who experienced Satepsi in different functions and times, giving special attention to Projective Methods, whose history remains to be shown.(AU)

Escala de potencial criativo no trabalho: análise dos itens via teoria de resposta ao item / Creative Potential at Work Scale: Analysis conducted using Item Response Theory / Escala potencial de trabajo creativo: análisis de ítems a través de la teoría de respuesta a ítems

O presente estudo teve como objetivo realizar a análise dos itens da Escala de potencial criativo no trabalho. A amostra foi composta por 377 participantes, de 18 a 73 anos (M = 33,1; DP = 10,0). Para isso, realizou-se a análise das propriedades psicométricas dos itens, notadamente a estimação da sua dificuldade e medidas de ajuste. Duas análises foram conduzidas. Na primeira, por meio do Modelo de Créditos Parciais, verificou-se os índices de dificuldade dos itens e/ou o nível de habilidade necessária para que o sujeito endosse o conteúdo apresentado no item. Todos os itens que compõem o instrumento apresentaram índices de infit e outfit adequados, com exceção de dois itens. Foi possível, ainda, elaborar o mapa de itens, a fim de identificar aqueles que se mostram mais proeminentes em discriminar indivíduos que apresentam nível de habilidade acima da média. De modo geral, os resultados encontrados nos estudos amparam evidências positivas de validade e precisão da escala. Sugere-se que novos estudos sejam conduzidos com o instrumental, notadamente sua normatização a fim de que o mesmo possa ser disponibilizado, futuramente, para uso profissional

This study aimed to analyze the items of the Scale of creative potential at work. The sample consisted of 377 participants, aged 18 to 73 years (M = 33.1; SD = 10.0). Therefore, the analysis of the psychometric properties of the items was performed, notably the estimation of their difficulty and adjustment measures. Two analyzes were conducted, the first, through the Graduated Response Model, aimed to estimate the difficulty of the items and / or the skill level necessary for the subject to endorse the content presented in the item. All items that make up the instrument presented adequate infit and outfit indices, except for two items. It was also possible to elaborate the item map, to identify those that are more prominent in discriminating individuals with above average skill level. Overall, the results found in the studies support positive evidence of scale validity and accuracy. It is suggested that further studies be conducted with the instrument, notably its standardization so that it can be made available for professional use in the future

When Happiness is Both Joy and Purpose: The Complexity of the Pursuit of Happiness and Well-Being is Related to Actual Well-Being.

People differ in how they define and pursue happiness and well-being (HWB). Previous studies suggested that the best way to achieve a high level of well-being might be to pursue different facets of HWB simultaneously. We expand on this idea and introduce the concept of complexity of HWB definitions to describe how many HWB definitions people endorse simultaneously, and the complexity of HWB-related intentions to describe how many unique facets of HWB people intend to pursue in everyday life. To operationalize these novel concepts, we developed two parallel measures that integrate psychological and philosophical definitions of HWB. In two independent studies (total N = 542), exploratory and confirmatory factor analyses revealed eight reliable and valid factors for both parallel scales: absence of negativity, positive attitude, tranquility, personal development, luck, joy and desires, purpose, and belonging. Complexity of HWB-related intentions was positively associated with all facets of well-being, whereas complexity of HWB definitions was only positively associated with some facets of well-being. HWB-related intentions and their complexity emerged as more important for the experience of well-being than HWB definitions and their complexity. These studies highlight the importance of a multifaceted conceptualization of HWB when investigating how the pursuit of HWB is related to actual levels of well-being.

Factor Structure of the Memory for Intentions Test (MIsT): A Conceptual Replication in Older Adults and People with HIV Disease.

OBJECTIVE: The Memory for Intentions Test (MIsT) is a clinical measure of prospective memory that has strong evidence for convergent, discriminative, and ecological validity. This study uses a conceptual replication design to evaluate the latent structure of the MIsT in two parallel samples who commonly experience prospective memory deficits: older adults and people living with HIV disease. PARTICIPANTS AND METHODS: Study participants included 303 people with HIV disease (ages 18-67) and 267 community-dwelling older adults (ages 50-91). Confirmatory factor analyses of the MIsT were conducted separately in each sample. We evaluated a one-factor model, as well as three two-factor models with the MIsT items loading onto each factor based on cue type, delay interval, or response modality. RESULTS: The one-factor model provided the best (and most parsimonious) fit to the data in both study samples. All two-factor models also demonstrated good fit statistics, although correlations between the two factors in each model were high and none of the two-factor models provided a significantly better fit than the one-factor model. CONCLUSIONS: Results of this conceptual replication study provide support for a robust factor structure of the MIsT across older adults and people with HIV disease. A total score for the MIsT provides the most parsimonious solution, although available evidence and theory also support the potential use of subscales (e.g., cue type). Future studies of the MIsT would be useful to determine its psychometrics in different clinical populations and across demographic factors (e.g., race/ethnicity).

A Validity Measure for the Automated Neuropsychological Assessment Metrics.

The Automated Neuropsychological Assessment Metrics (ANAM) is one of the most widely used and validated neuropsychological instruments for assessing cognition. The ANAM Test System includes a reporting tool, the ANAM Validity Indicator Report that generates scores for the embedded effort measure, the ANAM Performance Validity Index (APVI). The current study seeks to develop a proxy for the APVI, using raw subtest summary test scores. This would be useful for situations where the APVI score is unavailable (e.g., validity report not generated at the time of the assessment) or when the item level data needed to generate this score are inaccessible. ANAM scores from a large data set of 1,000,000+ observations were used for this retrospective analysis. Results of linear regression analysis suggest that the APVI can be reasonably estimated from the raw subtest summary test scores that are presented on the ANAM Performance Report. Clinically, this means that an important step in the interpretation process, checking the validity of test data, can still be performed even when the APVI is not available.

Age Diversity Management in Organizations Scale: development and evidence of validity / Escala Gestão da Diversidade Etária nas Organizações: desenvolvimento e evidências de validade / Escala Gestión de la Diversidad de Edades en las Organizaciones: desarrollo y evidencias de validez

This study aimed to develop the Age Diversity Management in Organizations scale for the Brazilian context and verify its evidence of validity. The process included five steps: proposal of its definition and development of the items according to the literature; content and semantic validity by judges; semantic validity by the target population; exploratory factorial analysis (EFA); and confirmatory factorial analysis (CFA). The EFA sample consisted of 674 workers from different organizations and the CFA of 722 workers. The final version of the scale was composed of 20 items (α =.91), divided into four factors: retirement preparation practices (5 items, α =.93); equal treatment for workers of different ages (6 items, a=.85), training to promote age diversity (5 items, α =.81), and management practices for older workers (4 items, α =.72). The theoretical and practical implications as well as the limitations of this measure are discussed. (AU)

Este estudo objetivou desenvolver e identificar os indícios de validade da escala Gestão da Diversidade Etária nas Organizações (GeDEO) para o contexto brasileiro.

La muestra de AFE consistió en 674 trabajadores de diferentes organizaciones, y la de AFC, en 722. La versión final contiene 20 ítems (α = 0,91), divididos en cuatro factores: prácticas de preparación para la jubilación (5 ítems, α = 0,93); igualdad de trato pata los trabajadores de diferentes edades (6 ítems, α = 0,85), capacitación para promover la diversidad de edades (5 ítems, α = 0,81) y prácticas de gestión para trabajadores mayores (4 ítems, α = 0,72). Se discuten las implicaciones teóricas y prácticas, así como las limitaciones de esta medida. (AU)

Traffic safety knowledge gain of ambulance drivers after simulator-based training.

BACKGROUND: Compared to other road users, ambulance drivers are at a higher accident risk while driving with warning lights and sirens. No standard exists for training or education for emergency medical service employees driving ambulances. Training programs should positively influence knowledge. However, knowledge gain can be influenced by several different factors. This study developed a knowledge test for ambulance drivers to determine influencing factors on knowledge and its gain by simulator-based training. METHODS: Two parallel knowledge test forms with 20 questions each were designed in several steps and tested on up to 174 participants. Questionnaires were used to study associated and influencing factors, such as objective experience, subjective attitudes, personality, motivation and demographic data. RESULTS: Test construction showed good overall parallelism of the two tests as well as reliability and sensitivity. There was no correlation between subjective and objective knowledge gain, but participants with higher subjective knowledge gain showed a higher variation in objective knowledge. Younger age, higher qualification, higher number of license classes, fewer traffic violations, and more traffic safety trainings were positively associated with knowledge, whereas less yearly driving mileage, more traffic safety trainings, and higher risk sensitivity positively influenced knowledge gain through the training. CONCLUSION: Knowledge and its gain through training are very low. Reasons for the lack of predictive power of some variables, such as motivation, personality and attitudes, are discussed. This study presents a new tool for testing knowledge on driving with warning lights and sirens. It shows the need for objective testing and for further research in this special area.

New observations on test architecture and construction of Jullienella foetida Schlumberger, 1890, the largest shallow-water agglutinated foraminifer in modern oceans.

We present new observations on Jullienella foetida Schlumberger, 1890, a giant agglutinated foraminifer with a leaf- or fan-like test reaching a maximum dimension of 14 cm, that is common on some parts of the west African continental shelf. The test wall comprises a smooth, outer veneer of small (<10 µm) mineral grains that overlies the much thicker inner layer, which has a porous structure and is composed of grains measuring several hundreds of microns in size. Micro-CT scans suggest that much of the test interior is filled with cytoplasm, while X-ray micrographs reveal an elaborate system of radiating internal partitions that probably serve to channel cytoplasmic flow and strengthen the test. Jullienella foetida resembles some xenophyophores (giant deep-sea foraminifera) in terms of test size and morphology, but lacks their distinctive internal organization; the similarities are therefore likely to be convergent. Based on micro-CT scan data, we calculated an individual cytoplasmic biomass of 3.65 mg wet weight for one specimen. When combined with literature records of seafloor coverage, this yielded an estimate of >7.0 g wet weight m-2 for the seafloor biomass of J. foetida in areas where it is particularly abundant. The relatively restricted distribution of this species off the north-west African coast at depths above 100 m is probably related to the elevated, upwelling-related surface productivity along this margin, which provides enough food to sustain this high biomass. This remarkable species appears to play an important, perhaps keystone, role in benthic ecosystems where it is abundant, providing the only common hard substrate on which sessile organisms can settle.

'I have high self-compassion': A face-valid single-item self-compassion scale for resource-limited research contexts.

The original 26-item Self-Compassion Scale (SCS; Neff, 2003) and 12-item Short-Form Self-Compassion Scale (SF-SCS; Raes et al., 2011) are scales commonly used in cross-sectional and longitudinal research to assess the global self-compassion construct and its six facets. We introduce the Single-Item Self-Compassion Scale (SISC; 'I have high self-compassion') to measure the global self-compassion construct in time-, space- and resource-limited contexts (e.g., daily diaries, experience sampling and nationally representative surveys). Additionally, the SISC will expand knowledge about self-compassion by providing researchers whose primary interest is not self-compassion with a convenient, face-valid option to measure self-compassion. Across 10 samples (four cross-sectional, four longitudinal and two 7-day daily diary; N = 2,477), we demonstrated that the SISC has acceptable psychometric properties. Specifically, the SISC was temporally consistent, correlated adequately with the SCS and SF-SCS, exhibited nearly identical correlational patterns when compared with the SCS and SF-SCS with a wide range of criterion measures (e.g., self-esteem, personality, affective and social functioning, mental health and demographic variables) and saved 12 min over a 7-day diary. Results replicated among students, community samples and across the United States, Turkey and Malaysia. Thus, we provide the field with an alternative measure of the global self-compassion construct that complements the SCS and SF-SCS.
