Optimism and Mental Health in Adolescence: a Prospective Validation Study of the Dutch Life-Orientation Test-Revised (LOT-R-A) for Adolescents.

The study aimed to examine the psychometric properties of the Dutch Life Orientation Test-Revised for Adolescents (LOT-R-A), a self-report questionnaire assessing dispositional optimism, and to evaluate the two-factor structure (optimism, pessimism). The LOT-R-A and the questionnaires measuring well-being (MHC-SF-A) and psychological problems (SDQ) were completed by 459 Dutch adolescents (178 boys and 281 girls) between the ages of 11 and 18 years at baseline and 281 adolescents at a four-week follow-up. The results confirmed the two-factor structure (optimism, pessimism) of the LOT-R-A. The findings provided evidence of internal consistency of scores ranging from low to good, and evidence of good test-retest reliability of scores. Further, scores of optimism were cross-sectionally positively associated with scores of positive emotions and well-being and negatively with scores of psychological problems and negative emotions, providing evidence of convergent and divergent validity of optimism scores with emotions, well-being, and psychological problems. Lastly, scores of optimism were prospectively positively associated with scores of well-being and negatively with scores of psychological problems, providing evidence of criterion validity of optimism scores with well-being and psychological problems. Based on these findings it can be concluded that the LOT-R-A is a valid instrument to examine optimism among adolescents. Future research can help to elucidate the role of optimism in mental health interventions and can gather knowledge on how these interventions can be refined to optimally cultivate optimism during the developmental period of adolescence.

Pelvic floor distress inventory (PFDI)-systematic review of measurement properties.

The Pelvic Floor Distress Inventory (PFDI) and PFDI-20 have been translated and validated into several languages ​​with different measurement property values ​​and are recommended by the International Consultation on Incontinence (ICI) as grade A for assessing pelvic floor dysfunction. Thus, the aim of the current study was to investigate the measurement properties of the PFDI and PFDI-20. Systematic review conducted in August 2020 through a search performed in PubMed, SCOPUS, WoS, ScienceDirect, CINAHL, and Google Scholar for studies that evaluated the measurement properties of the PFDI and PFDI-20. The data were analyzed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). Initially, 2857 studies were found, and 7 studies on PFDI and 25 on PFDI-20 were analyzed. The PFDI presented high quality of evidence for hypothesis testing, moderate for test-retest reliability and responsiveness, and very low quality of evidence for content validity. The PFDI-20 presented high quality of evidence for criterion validity, hypothesis testing, and responsiveness, moderate quality for test-retest reliability and measurement errors, and very low quality of evidence for content validity. It was not possible to rate the quality of evidence of the internal consistency of the PFDI and PFDI-20. No studies assessed the cross-cultural validity. Only the hypothesis testing presented high quality of evidence for the PFDI. Criterion validity, hypothesis testing, and responsiveness presented a high quality of evidence for the PFDI-20. Due to the high degree of recommendation of the PFDI and PFDI-20 given by the ICI, further studies are needed to reevaluate all the measurement properties of these instruments.

Evidence for use of damage control surgery and damage control interventions in civilian trauma patients: a systematic review

BackgroundAlthough damage control (DC) surgery is widely assumed to reduce mortality in critically injured patients, survivors often suffer substantial morbidity, suggesting that it should only be used when indicated. The purpose of this systematic review was to determine which indications for DC have evidence that they are reliable and/or valid (and therefore in which clinical situations evidence supports use of DC or that DC improves outcomes).MethodsWe searched 11 databases (1950–April 1, 2019) for studies that enrolled exclusively civilian trauma patients and reported data on the reliability (consistency of surgical decisions in a given clinical scenario) or content (surgeons would perform DC in that clinical scenario or the indication predicted use of DC in practice), construct (were associated with poor outcomes), or criterion (were associated with improved outcomes when DC was conducted instead of definitive surgery) validity for suggested indications for DC surgery or DC interventions.ResultsAmong 34,979 citations identified, we included 36 cohort studies and three cross-sectional surveys in the systematic review. Of the 59 unique indications for DC identified, 10 had evidence of content validity [e.g., a major abdominal vascular injury or a packed red blood cell (PRBC) volume exceeding the critical administration threshold], nine had evidence of construct validity (e.g., unstable patients with combined abdominal vascular and pancreas gunshot injuries or an iliac vessel injury and intraoperative acidosis), and six had evidence of criterion validity (e.g., penetrating trauma patients requiring > 10 U PRBCs with an abdominal vascular and multiple abdominal visceral injuries or intraoperative hypothermia, acidosis, or coagulopathy). No studies evaluated the reliability of indications.ConclusionsFew indications for DC surgery or DC interventions have evidence supporting that they are reliable and/or valid. DC should be used with respect for the uncertainty regarding its effectiveness, and only in circumstances where definitive surgery cannot be entertained.

Social validity and psychometric properties of Teacher Impression Scale – A pilot study

ABSTRACT Teachers of inclusive early childhood education (ECE) are responsible for monitoring children’s social skills achievement, and promoting social play between children with and without special educational needs (SEN). The Teacher Impression Scale (TIS) is an observational assessment developed for this purpose. This study aims to explore the social validity of the Swedish version of TIS, TIS-S, and to evaluate its effectiveness in identifying participants for peer-mediated interventions in Swedish preschools; by also testing the internal consistency, and the construct and criterion-related validity of the scale. The teachers (N = 16) observed children with SEN (n = 16) and without SEN (n = 16) in social play situations with TIS-S and subsequently answered a survey. Data were analysed quantitatively and qualitatively. Results demonstrate that the TIS-S has high internal reliability. The TIS-S also discriminated between the groups of children with and without SEN, which provided evidence of construct and criterion validity. Social validity was verified as the teachers reported that TIS-S was suitable for recognising individual children’s need for support in interactions with peers, planning for adaptations for all children in the social learning environment, and reflecting on the complexity of children’s social behaviour in play.

Psychometric Properties of the Bullying Participant Behaviors Questionnaire (BPBQ) among Chinese Middle School Students

The Bullying Participant Behaviors Questionnaire (BPBQ) is an efficient self-report measure for investigating bullying participant role behaviors. The present study evaluated the psychometric properties of the BPBQ in a Chinese middle school sample. A total of 516 middle school students (47.7% girls; age range = 12–14 years) were recruited from an urban middle school in China. Results revealed that a five-factor model fit the data best. Correlations between the BPBQ subscale scores and the external criterion variables, including empathy and sympathy, moral disengagement, and trait anger, provided evidence of criterion validity. Furthermore, the BPBQ had good alpha reliability and moderate to good test-retest reliability. In conclusion, the BPBQ is a promising assessment tool to measure bullying participant behaviors among Chinese middle school students.

The Withdrawal Assessment Tool to identify iatrogenic withdrawal symptoms in critically ill paediatric patients: A COSMIN systematic review of measurement properties

The Withdrawal Assessment Tool (WAT-1) is one of the most widely used clinician-reported outcome measures to evaluate iatrogenic withdrawal symptoms (IWS) in critically ill children. However, the WAT-1's measurement properties have not been aggregated. Aggregating psychometric research on the WAT-1 will enhance appropriate use, and outline gaps for future empirical research. The aim of this systematic review is to critically appraise, compare, and summarize the measurement properties and evidence quality, and describe the interpretability and feasibility of the WAT-1 for identifying IWS symptoms in critically ill children. A systematic search of Medline, Embase and CINAHL was conducted from inception to 15 April 2020. Study inclusion/exclusion, data extraction, and measurement property evidence and the modified GRADE quality scoring were applied according to the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines. Six studies were included in the review. There was sufficient, high-quality evidence for reliability, structural validity, criterion validity, measurement error, construct validity, and feasibility. More information is required to support the WAT-1's content validity, responsiveness, internal consistency, cross-cultural validity, and interpretability according to COSMIN guidelines. The results of this review indicate that the WAT-1 is a precise, easy to use measure of IWS in critically ill children despite some measurement property inconsistencies and gaps in the publication record. More information is required to support its content validity, responsiveness, internal consistency, cross-cultural validity, and interpretability.

Adaptation and Validation of the Authoritative School Climate Survey in a Sample of Chilean Adolescents.

Authoritative school climate is a relevant and novel construct that improves the academic performance and social-emotional development of students. This study aimed to evaluate the psychometric properties of reliability and validity of the Authoritative School Climate Survey (ASCS) in a sample of Chilean adolescents. A cross-sectional study was carried out, in which 808 students from 12 schools in Chile participated (55.1% men and 44.9% women), with a mean age of 15.94 (SD = 1.32). The results obtained through exploratory and confirmatory factor analyzes ratified the hypothesized structure of two correlated factors. As expected, evidence of criterion validity showed significant relationships between the measures of authoritative school climate and attitude toward institutional authority. This study provides evidence regarding the psychometric quality of the scale to assess authoritative school climate, allowing its use in the Chilean context.

Psychometric Examination of the Abbreviated Version of the Dual School Climate and School Identification Measure-Student (SCASIM-St15) in a Sample of Chilean Adolescents.

School climate is a multidimensional construct that has been related to a series of psychological, social, and school variables. The dual school climate and school identification measure-student (SCASIM-St) is a measure that has a multidimensional factor structure, with four first-order factors and a second-order factor, plus an independent factor that evaluates school identification. However, the SCASIM-St is long, with 38 items measuring school climate. The first objective of this study was to examine the psychometric properties of reliability and validity of the abbreviated version of the dual school climate and school identification measure-student (SCASIM-St-15), for use in contexts with time limitations or for explanatory studies that need to apply multiple instruments simultaneously. The second objective was to analyze the degree of invariance for the groups: sex, type of education, and age. The sample was made up of 2,044 students of both sexes (49.1% women and 50.9% men), with a mean age of 14.64 (SD = 0.718), representing 27 secondary schools in Chile. The results indicated that the SCASIM-St15 presents adequate indicators of reliability and construct validity. Evidence of external criterion validity confirmed significant associations with the Attitudes to Institutional Authority in Adolescence Scale measure. The results of the factorial invariance analysis indicate that the SCASIM-St15 remains stable up to the level of metric invariance for the variable sex and the level of scalar invariance for the variables type of education and age. The study concluded that despite the significant decrease in the number of items, the SCASIM-St15 measures school climate in a reliable and valid way, without losing its theoretical and conceptual robustness.

A critical review of animal-based welfare indicators for polar bears (Ursus maritimus) in zoos: Identification and evidence of validity

AbstractCaptive polar bears (Ursus maritimus) are well-documented as being prone to behavioural disorders and, as a result, their welfare is the cause of increasing concern. There is therefore a need for an evidence-based approach to the assessment of the welfare of this species and identification of valid welfare indicators is the first step towards achieving this. To this end, a critical evaluation of peer-reviewed literature was undertaken. Searches of Web of Science and Scopus took place in May 2020 for publications relevant to the welfare of captive polar bears which met inclusion criteria. Further, validity of extracted indicators was assessed via investigation of evidence of content, construct and criterion validity along with strength of evidence at publication-level. Database searches and snowballing unearthed 46 publications included for review. Identified indicators were sorted into nine behavioural, four physiological (based on physiological or biological sampling) and five physical (based on visual inspection) categories. Among behavioural indicators, the strongest evidence of validity was found for abnormal behaviour. For the physiological indicators, validity was only established for faecal glucocorticoid metabolite concentration. Content validity was assumed for all physical indicators. Generalisability and strength of evidence was generally compromised by low sample sizes and experimental limitations, and only a small number of papers investigated welfare indicators directly, resulting in a paucity of validated indicators. Potential welfare indicators that warrant further validation are highlighted. Overall, this review provides an overview of current valid and promising welfare indicators along with identified gaps in knowledge, relevant for the provision of a methodology for assessing and monitoring welfare of captive polar bears.

Team boosting behaviours:Development and validation of a new concept and scale

ABSTRACT In teams, some people are truly noticed when present, and sorely missed when absent. Often they are described as the “life of the party”, but in a formal team context, we refer to their behaviors as “team boosting behavior”. These behaviors have the potential to affect the team’s processes. In three consecutive studies, we conceptualized these behaviors and developed and validated a questionnaire to measure them. In Study 1, we defined team boosting behaviors as the extent to which team members exhibit mood-enhancing, energizing, and uniting behaviors, directed towards team members. In Study 2, we developed and validated an instrument to measure team boosting behaviors using a sample of team members in work and sports teams (N = 385). Results supported a three-factor structure and indicated positive relationships with conceptually similar constructs. In Study 3, we cross-validated the three-factor structure among the members of 120 work teams and offer evidence for convergent and criterion validity of the Team Boosting behavior scale. The behaviors related positively to a positive team climate, team work engagement, and leader-rated team performance. The scale provides a useful tool for future empirical research to study the role of individual team boosting behaviors in shaping team processes and outcomes.

Development and Validation of a Scale to Measure Entrepreneurial Hustle

Entrepreneurial hustle refers to urgent and unorthodox actions that entrepreneurs take to move their ventures forward. Recent literature suggests entrepreneurial hustle is important for venture development. However, the literature on entrepreneurial hustle is limited without a valid and reliable measurement scale. We first elaborate the two dimensions of entrepreneurial hustle and specify its theoretical connections with other constructs. We then develop and validate a scale to measure entrepreneurial hustle. In Study 1, we generate items for the scale based on our theoretical developments and find evidence to support the content validity of these items. In Study 2, we collect additional data (N=232) to assess convergent, criterion, and discriminant validity and confirm factor structure. The results of Study 2 confirm entrepreneurial hustle is a second-order formative construct composed of two first-order reflective dimensions—urgency and unorthodoxy. Results also provide evidence for convergent, criterion, and discriminant validity. We contribute to the literature on entrepreneurial action by providing evidence that hustle is a valid behavioral construct and can be reliably measured with our new measurement scale.

Адаптация Стратклайдского опросника (SI-22) на российской выборке

This study aims to clarify the methodological status of the category “activity experience”. A sample of the study consists of first-year students of a Moscow university. Study 1 (N = 104) attended by respondent aged 17 to 28 years (M = 18.30; SD = 1.40), 82% are female, and in study 2 (N = 93), aged 17 to 28 20 years old (M = 18.02; SD = 0.61), 55% are female. Study 2 includes three measurements of activity-related experiences with an interval of 10—15 days. We use the Activity-Related Experience Assessment (AREA), the Universal Perceived Locus of Causality Scale (UPLOC), the Responsibility Scale, and a brief version of the Psychological Health Continuum. The results of the study demonstrate that the activity-related experiences are neither personality traits, that are inherent in the individual regardless of situations, nor emotional states that change over time. Evidence of reliability, construct validity and criterion validity of the Activity- Related Experiences Assessment Scale is given. The measure of academic success is better predicted not by those experiences that are manifested during study activities, but those that arise along on the way to university. There is a slight effect of the influence of time on the measure of effort.

Validity of the social support assessment scale in mothers of hospitalized premature neonates

Abstract Mothers staying with their premature babies, hospitalized in the Neonatal Intensive Care Unit tend to have reduced contact with friends and family, so it is pertinent that the perceived social support be evaluated during this period. This study aims to verify the validity of the Scale to evaluate the perceived social support by mothers of hospitalized premature babies. It is composed by the following dimensions: affective support; material support; informational support; emotionalsupport; embracing support; and attentional support. It is a sectional analytical study. The participants were 218 mothers of premature babies hospitalized in the Neonatal Intensive Care Unit. The social support Scale for mothers of hospitalized premature neonates demonstrates satisfactory psychometric quality, presenting evidence of criterion validity, internal consistency and internal structure.

Escala de Atitudes frente à Homossexualidade (ATHO): construção e produção de evidências de validade / Attitudes towards Homosexuality Scale (ATHO): construction and production of evidence of validity

O objetivo do presente artigo foi produzir evidências de validade para uma medida de homofobia. Para isso, foram desenvolvidos processos de adaptação de itens de uma escala de homofobia sutil e manifesta e um survey online com 985 indivíduos brasileiros, maiores de 18 anos e como média de idade de 26,01 anos (DP = 7,52). Além desse instrumento, foi aplicado um questionário sócioidentitário, uma escala de preconceito contra diversidade sexual e de gênero e uma escala de homofobia internalizada. Com a amostra selecionada foram executadas uma Análise Fatorial Exploratória e uma Análise Fatorial Confirmatória, além de medidas para identificar evidências de validade de critério, convergente e concorrente. Os resultados apontaram para a possibilidade de existência de dois modelos na Escala de Atitudes frente à Homossexualidade (ATHO), um com dois fatores, Atitudes Distais (α = 0,855) e Atitudes Proximais (α = 0,819), e outro com fator único (α = 0,881), os dois com ajustes satisfatórios. A correlação com outra medida de preconceito contra diversidade sexual foi significativa, positiva e com elevada magnitude (r = 0,851). Homens, moradores de cidades pequenas ou médias, pessoas que estudaram até o Ensino Médio e indivíduos heterossexuais apresentaram significativamente maiores pontuações na ATHO do que os grupos pares. Esses resultados atestam que há indícios de validade na escala, indicativos de boas propriedades psicométricas e que ela pode ser utilizada para investigação da homofobia.

Body acceptance by others: Refinement of the construct, and development and psychometric evaluation of a revised measure – The Body Acceptance by Others Scale-2

The Body Acceptance by Others Scale (BAOS) measures the degree to which individuals perceive body acceptance by others, but its factor structure is questionable. Here, we developed a revision of the BAOS (i.e., the BAOS-2) by designing novel items reflective of generalised perceptions of body acceptance by others. In three studies, we examined the psychometrics of the 13-item BAOS-2. Study 1, with United Kingdom adults (N = 601), led to the extraction of a unidimensional model of BAOS-2 scores and provided evidence of 4-week test-retest reliability. Study 2, with United Kingdom adults (N = 423), indicated that the unidimensional model of BAOS-2 scores had adequate fit and that scores were invariant across gender. Study 2 also provided evidence of convergent, construct, criterion, discriminant, and incremental validity. Study 3 cross-validated the fit of the unidimensional model in adults from the United State (N = 503) and provided evidence of invariance across gender and national group. Internal consistency coefficients of BAOS-2 scores were adequate across all three studies. There were no significant gender differences in BAOS-2 scores and a significant national difference had a negligible effect size. Thus, the BAOS-2 is a psychometrically-sound measure that can be utilised in future research.

Diabetes distress instruments in adults with Type 1 diabetes: A systematic review using the COSMIN (COnsensus-based Standards for the selection of health status Measurement INstruments) checklist.

To identify all extant instruments used to measure diabetes distress in adults with Type 1 diabetes and to evaluate the evidence for the measurement properties of these instruments. Medline, Embase, CINAHL plus and PsycINFO were systematically searched from inception up until 12 March 2020 for all publications which evaluated the psychometric properties of diabetes distress measurement instruments. The quality of the methodology and the measurement properties in the identified studies were evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. Seven out of the 7656 articles retrieved in the search were included in the final review. Four diabetes distress measurement instruments were identified, none of which displayed evidence for all measurement properties specified in the COSMIN guidelines. The Problem Areas in Diabetes-11 (PAID-11) demonstrated the best psychometric properties, displaying strong evidence for structural validity, internal consistency, hypothesis testing, responsiveness and criterion validity. The Problem Areas in Diabetes scale (PAID) was the most frequently investigated instrument, demonstrating good relevance and hypothesis testing across four studies; however, concerns remain over its factor structure. The PAID-11 appears to be the most psychometrically sound instrument for measuring diabetes distress in adults with Type 1 diabetes, displaying strong evidence for a range of measurement properties. However, as only one study evaluated this instrument and its content validity has yet to be assessed, further validation is warranted. Additional qualitative work is needed to assess the content validity of these instruments among individuals with Type 1 diabetes.

A German Validation of Four Questionnaires Crucial to the Study of Time Perception: BPS, CFC-14, SAQ, and MQT.

We aimed to validate four established questionnaires related to time perception in German (Consideration of Future Consequences-14 scale (CFC-14), Boredom Proneness Scale (BPS), Metacognitive Questionnaire on Time (MQT), and Self-Awareness Questionnaire (SAQ)) using a back-translation method. Exploratory factor analyses were conducted on the data of 273 German-speaking participants to evaluate the factorial structures. Internal consistencies indicated good reliability values of the questionnaires and the respective subscales, except for the MQT. Intercorrelations between the questionnaires were examined to test their external validities and gain additional insight into the associations among the constructs. The consideration of future consequences was negatively linked to boredom proneness, whereas interoceptive awareness of one’s bodily sensations was positively associated with boredom proneness. Additionally, interoceptive awareness was linked to metacognitive beliefs about which factors influence time perception. The results are discussed in regard to human time perception. Conclusion: The validated German questionnaires can now be used in research projects. Initial observations on how the questionnaires are related to each other fit the current knowledge on how human time perception works, yielding the first evidence for the external validity of the German versions of these established questionnaires. For evidence of criterion validity, future studies should more thoroughly investigate the external validities analyzing the correlations with other validated measures.

Development and Validation of the Adolescent Sexting Scale (A-SextS) with a Spanish Sample.

“Sexting” is generally defined as the exchange of sexual media content via the internet. However, research on this topic has underscored the need to seek greater consensus when considering different conceptual elements that make up this definition. The aim of this study was to develop and validate an instrument for measuring sexting among adolescents, in order to cover a gap identified in the previous literature. The Adolescent Sexting Scale (A-SextS for short) was developed for validation on a sample of 579 Spanish secondary school pupils between the ages of 11 and 18. Evidence for face, content, concurrent, and criterion validity were assessed. A comprehensive set of 64 items, covering six defining characteristics of sexting (e.g., actions, recipient, media format, degree of sexual explicitness), was constructed after conducting an extensive literature review, two discussion groups, and a pilot study. Sexting prevalence rates measured by A-SextS were mostly concurrent with those found in previous studies. A-SextS subscales produced statistically significant positive associations with pornography consumption and physical sexual intercourse. The study shows that A-SextS can be an integrating instrument that facilitates a rigorous and comprehensive assessment of adolescent sexting experiences, as well as the formulation of an operationalized definition of the practice of sexting.
