The measure of empathy in early childhood: Testing the reliability, validity, and clinical utility of scores in early childhood.

Empathy is a critical socioemotional skill that motivates prosocial behavior and supports the ability to respond to the emotions of others. Although accurate measurement of empathy in young children is critical for identifying and remediating empathy deficits, currently available parent-report measures of childhood empathy have several psychometric limitations. The present study tested the reliability, validity, and clinical utility of scores on the Measure of Empathy in Early Childhood (MEEC), a new multidimensional, parent-report empathy scale, in 4- to 7-year-old children. The psychometric properties of MEEC scores were assessed by examining their associations with criterion, construct, discriminant, and clinical validity measures. A sample of 129 parents of community and clinic-referred children (Mage = 5.62 years, SD = 1.01, 65.9% boys) completed the MEEC and other relevant parent-report questionnaires. Internal consistencies (α = .79-.93) of MEEC scores were good. Correlations between MEEC scores and parent-report measures, sex, and age robustly supported their validity in 4- to 7-year-old children. Logistic regression analyses demonstrated that MEEC scores significantly predicted membership into clinical subgroups characterized by empathy deficits. Linear regression analyses indicated that prosocial behavior and sympathy MEEC subscales, but not affective empathy, statistically predicted parent-reported callous-unemotional traits. Theoretical and clinical implications of these findings for developmental models of empathy and empathy-related disorders are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

A psychometric evaluation of a new social subscale for the Common Misconceptions about Traumatic Brain Injury (CM-TBI) questionnaire: toward the CM-TBI-II

ABSTRACT Objective Existing TBI misconception measures are critiqued for failing to measure postinjury social experiences. This study developed a social subscale for the Common Misconceptions about TBI (CM-TBI) questionnaire for use in the general public. Methods Seven experts independently review items drawn from the literature. Shortlisted items were administered online to 158 adults (aged ≥18 years; 51% postschool educated; 60% no TBI experience), the CM-TBI, and a measure of construct validity (a published TBI-adaptation of the Community Attitudes Towards the Mentally Ill; CAMI-TBI). One week later, the new items were redeployed (n = 46). Results Expert review and iterative correlations identified a 10-item social subscale (internal consistency, test-retest reliability, α’s>.80). When added to the CM-TBI (ie. CM-TBI-II), the internal consistency was .71. The social subscale was significantly correlated with CAMI-TBI measures (p’s <.05, r’s > .3). There was no significant difference on the social subscale for education subgroups (school vs post-school, p = 0.056) or previous TBI experience; but there was a difference for the CM-TBI-II (post-school>school; Cohen’s d = 7.83, large effect). Conclusion This study found strong preliminary psychometric support for a new social subscale, administered as the CM-TBI-II. This subscale shows promise as a measure of misconceptions about social functioning post-TBI. The CM-TBI-II could support evaluations of programs aiming to improve social engagement and community participation for people with TBI.

Screening for post-intensive care syndrome: Validation of the Healthy Aging Brain Care Monitor Self-Report Chinese version.

The Healthy Aging Brain Care Monitor Self-Report (HABC-M SR) is a tool to evaluate physical, mental and cognitive impairments. It has been validated in several countries for post-intensive care syndrome (PICS) assessment, but there is no Chinese version yet. The aim of this study is to translate and cross-cultural adapt HABC-M SR, and validate its psychological properties among Chinese ICU survivors. This is a cross-sectional study. the HABC-M SR was translated into Chinese and validated in intensive care unit survivors (n = 145). Measures of internal consistency, construct validity, concurrent validity, and content validity were evaluated. A 19-item Chinese version of HABC-M SR was yielded, with good reliability (Cronbach's α = 0.92) and validity (the variance was 64.4%, overall content validity was 0.91, and correlation coefficients were 0.62-0.90). The 19-item Chinese version HABC-M SR is a reliable and valid tool for PICS assessing and may be regarded as a standard measurement. The Chinese version HABC-M SR may help in selecting PICS high-risk survivors for ICU follow-up interventions. The HABC-M SR can also be regarded as a standard specific PICS measurement, thus promote the comparability between studies and transformation of the clinical evidence.

Construction &amp; Validation of Civic Sense Scale (CSS) in Urdu Language for Pakistani Secondary School Students

Civic sense plays a crucial role in human life. It determines the success and usefulness of a citizen in a society. The civic sense consists of both civic knowledge and civic practices. The students’ civic knowledge or self-perception of civic sense improves their civic practices in the community. This paper describes constructing and validating the Civic Sense Scale (CSS). This scale is prepared to measure students’ civic knowledge and civic practices. Generalized Structural Component Analysis (GSCA) technique is applied in this study. This scale was administered to 1200 Federal Government Educational Institutions students studying in 10th grade in Pakistan. A total of 1196 students out of 1200 students responded to the questionnaire. The data was collected from students through a stratified sampling technique. Both self-perception and civic practices on civic sense consisted of 45 items. There were 23 and 22 items on Civic Sense Scale on self-perception and civic practices, respectively. The reliability indicator Cronbach’s alpha and Rho were observed to be more than 0.7. Likewise, the construct validity, convergent and discriminant validity measures were in acceptable ranges. These show that Civic Sense Scale (CSS) is highly recommended to measure civic sense and its practices in the educational setting. Initially, this study was limited to secondary school students in Federal Government Educational Institutions of Pakistan.

Presenting the direct intercultural effectiveness simulation: an implicit trait policy on intercultural competence.

An implicit trait policy (ITP) represents the interaction between a personal disposition and general domain knowledge on how to effectively handle a specific (intercultural) situation. Such an ITP is a proven construct to create instruments that can predict future effective behavior. Moreover, such a simulation can provide valuable proxies for actual (future) behavior, as measures of (future) real life intercultural interactions are not always available. In a series of three studies (N1 = 224, N2 = 291, N3 = 478), the present research introduces a "Direct Intercultural Effectiveness Simulation" or DIES, an instrument that simulates intercultural effectiveness by directly tapping into an ITP on intercultural competence. First and foremost, the present research demonstrates that the DIES instrument generates reliable and construct-valid measures of intercultural effectiveness. Second, the DIES instrument also shows expected converging and diverging patterns when correlated with a nomological network on intercultural effectiveness. And third, the DIES measure is further validated by integration into an ITP framework of intercultural effectiveness based on theoretical and empirical accounts from literature. The DIES instrument generates a reliable and valid measure of intercultural effectiveness by tapping into an ITP on intercultural competence. Theoretically, the present research integrates the instrument into literature by empirically verifying an ITP framework of intercultural effectiveness. In practice, the DIES instrument can be used as an awareness or training proxy for actual behavior to tackle important problems like ethnic prejudice and discrimination.

Developing and validating a Japanese version of the Plymouth Sensory Imagery Questionnaire.

Mental imagery refers to the representation of stimuli that are not physically present and has long been a subject of interest in psychology. However, most research on mental imagery has been limited to visual images, with other types of imagery, such as sound and smell, receiving little attention. A possible reason for this is the lack of appropriate scales to measure the vividness of multisensory imagery. The Plymouth Sensory Imagery Scale (Psi-Q) has been developed to address this issue and has been used in several studies to measure the vividness of seven imageries: vision, sound, smell, taste, touch, body, and feeling. In this study of 400 participants in Japan, the Psi-Q was translated into Japanese and tested for reliability and validity. The results showed good internal reliability and retest reliability and moderate to high correlations with other measures of construct validity, including mindfulness, Big Five, and life satisfaction. Additionally, there is no significant difference in total Psi-Q scores between the Japanese and British samples, although some differences are found in individual sensory imagery abilities. This study provides valuable insights into multisensory mental imagery, and it is expected that research dealing simultaneously with the responses of multisensory modalities will further accumulate.

The Situated Assessment Method (SAM2): Establishing individual differences in habitual behavior.

From the perspectives of grounded, situated, and embodied cognition, we have developed a new approach for assessing individual differences. Because this approach is grounded in two dimensions of situatedness-situational experience and the Situated Action Cycle-we refer to it as the Situated Assessment Method (SAM2). Rather than abstracting over situations during assessment of a construct (as in traditional assessment instruments), SAM2 assesses a construct in situations where it occurs, simultaneously measuring factors from the Situated Action Cycle known to influence it. To demonstrate this framework, we developed the SAM2 Habitual Behavior Instrument (SAM2 HBI). Across three studies with a total of 442 participants, the SAM2 HBI produced a robust and replicable pattern of results at both the group and individual levels. Trait-level measures of habitual behavior exhibited large reliable individual differences in the regularity of performing positive versus negative habits. Situational assessments established large effects of situations and large situation by individual interactions. Several sources of evidence demonstrated construct and content validity for SAM2 measures of habitual behavior. At both the group and individual levels, these measures were associated with factors from the Situated Action Cycle known to influence habitual behavior in the literature (consistency, automaticity, immediate reward, long-term reward). Regressions explained approximately 65% of the variance at the group level and a median of approximately 75% at the individual level. SAM2 measures further exhibited well-established interactions with personality measures for self-control and neuroticism. Cognitive-affective processes from the Situated Action Cycle explained nearly all the variance in these interactions. Finally, a composite measure of habitualness established habitual behaviors at both the group and individual levels. Additionally, a composite measure of reward was positively related to the composite measure of habitualness, increasing with self-control and decreasing with neuroticism.

Validating the Perceived Active School Travel Enablers and Barriers-Parent (PASTEB-P) Questionnaire to Support Intervention Programming and Research.

A child's ability to participate in active school travel (AST) is complicated by several factors. Of particular note are parental controls, which are informed by their perceptions of the local built and social environments, assessments of their child's skills, and convenience preferences, among other considerations. However, there is currently a lack of AST-specific scales that include validated parental perception measures related to such notable barriers and enablers, or those that tend to frame their AST decision-making processes. Framed within the social-ecological model of health behaviour, the aims of the present paper were thus threefold, specifically to (1) outline and test the construct validity of measures delineating parental perceptions of barriers and enablers to AST, (2) evaluate the reliability and consistency of the developed measures, and (3) connect these measures to develop broader constructs for use in the Perceived Active School Travel Enablers and Barriers-Parent (PASTEB-P) questionnaire. To achieve these aims, a mixed-methods approach featuring cognitive interviews and surveys, along with qualitative (thematic analysis) and quantitative (Cohen's Kappa, McDonald's Omega, and confirmatory factor analysis) analyses, was applied across two studies. The validation processes of the two studies resulted in the development of fifteen items comprising seven distinct constructs (barriers: AST Skills, Convenience, Road Safety, Social Safety, and Equipment Storage; enablers: Supportive Environment and Safe Environment) related to parental perceptions of AST. The developed PASTEB-P questionnaire can be used to inform and evaluate AST intervention programming and can be applied for AST research purposes.

New measures to assess the “Other” three pillars of food security–availability, utilization, and stability

BackgroundIn recent reviews of available measures, no existing measures assessed all four pillars of food security and most only assessed one or two pillars–predominantly the access pillar. The purpose of this study was to preliminarily develop novel measures of availability, utilization, and stability that are complementary to the USDA’s household food security survey measure (HFSSM).MethodsA formative phase included an expert advisory group, literature scans, and interviews with individuals experiencing food insecurity. From April-June 2021, the new measures were piloted in five states (California, Florida, Maryland, North Carolina, and Washington). The cross-sectional pilot survey included the new measures (perceived limited availability, utilization barriers, and food insecurity stability), scales and items for validation (e.g., food security, and self-reported dietary and health outcomes), and demographic questions. Exploratory factor analysis was used to assess dimensionality, internal consistency was assessed using Kuder-Richardson formula 21 (KR21), and convergent and discriminant validity were assessed using Spearman’s correlation coefficients. Also, a brief screener version was created for the utilization barriers measure that may be necessary for certain applications (e.g., clinical intake screening to inform referrals to assistance programs).ResultsThe analytic samples (perceived limited availability (n = 334); utilization barriers (n = 428); food insecurity stability (n = 445)) were around 45 years old on average, most households had children, over two-thirds were food insecure, over three-fourths were women, and the samples were racially/ethnically diverse. All items loaded highly and unambiguously to a factor (factor loadings range 0.525–0.903). Food insecurity stability showed a four-factor structure, utilization barriers showed a two-factor structure, and perceived limited availability showed a two-factor structure. KR21 metrics ranged from 0.72 to 0.84. Higher scores for the new measures were generally associated with increased food insecurity (rhos = 0.248–0.497), except for one of the food insecurity stability scores. Also, several of the measures were associated with statistically significantly worse health and dietary outcomes.ConclusionsThe findings support the reliability and construct validity of these new measures within a largely low-income and food insecure sample of households in the United States. Following further testing, such as Confirmatory Factor Analysis in future samples, these measures may be used in various applications to promote a more comprehensive understanding of the food insecurity experience. Such work can help inform novel intervention approaches to address food insecurity more fully.

Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) questionnaire is a measurement tool for assessing health status and wellbeing of disabled children, which evaluates children's quality of life from the caregiver point of view. The aim of our work was the Hungarian translation and cultural adaptation of the questionnaire and also validation of the CPCHILD on Hungarian cerebral palsy patients. Further aim was to test the eligibility of the questionnaire for superficial assessment of caregiver's psychological attitudes. Translation of the questionnaire was carried out according to the Beaton's guidelines. Test-retest, interrater reliability (ICC) and also internal consistency (Cronbach-alpha) were calculated for reliability. The importance of the questions was assessed for face validity and known group validity test was done to measure construct validity. For examining parental attitudes, the patients were divided into ambulatory and non-ambulatory groups and the 36 quality of life questions of the 7th domain were used to find relations. During test-retest reliability measurements, the ICC was 0.96 (95% CI: 0.88-0.98), and Cronbach-alpha exceeded the minimal expected value of 0.7 (0.74-0.97) except in the 5th domain (0.67), while measuring interrater reliability the ICC was 0.87 (95% CI 0.70-0.94). Face validity was above the 2.0 threshold in every question (2.6-4.5; mean: 3.4 ± 1.34) and the known group validity calculations showed significant differences between the CPCHILD scores of ambulatory and non-ambulatory groups. Examining parental attitudes, a significant difference was also shown among the parents of ambulatory and non-ambulatory children in assessing the importance of sitting in the quality of life of their children (2.89 ± 1.28 vs. 3.51 ± 0.82; p<0.01). The final outcome of our study is that CPCHILD questionnaire has become widely accessible in Hungarian language. Our result, that the answers referring to the sitting abilities and the activities should be carried out in sitting position, was significantly different among the caregivers of the ambulatory and non-ambulatory children, showing that the parents of the GMFCS IV and V category children evaluate the importance of sitting ability higher compared to those parents who care for GMFCS I, II and III category children. Furthermore, the results draw attention to the wellbeing and health of the children measurable with CPCHILD as well as that parental caregiver attitudes can be recognized which may give further help in finding the balance between expectations and possibilities during the rehabilitation of cerebral palsy children.

On the construct and perceptual validity measures of L1-based vs. L2-based elicitation as a measure of L2 classroom performance assessment

This study aimed at investigating the English as a foreign language (EFL) learners’ perceptions of L1-based and L2-based elicitations in the English classroom employing an explanatory sequential mixed-method design. Ninety-seven Iranian intermediate EFL learners of English have been selected from Islamic Azad University (Science and Research Branch) in Tehran Province using a convenient sampling method. Of these, in the qualitative phase, 15 individuals were selected through a convenience sampling method as the focus group (N = 15; n = 8 for the L1 group and n = 7 for the L2 group). In the quantitative phase, 90 intermediate EFL learners were selected. The selected participants’ L2 performances were assessed through L1-based and L2-based elicitation techniques. They completed two validated researcher-made questionnaires to capture their perceptions of the elicitation techniques. Accordingly, five separate exploratory factor analyses were run to investigate the underlying constructs of the five components of the L1-based and L2-based perception questionnaires, the results of which showed that the correlation matrices were not singular and there were perfect correlations among all variables of L1-based and L2-based perception questionnaires. The findings show that the majority of respondents prefer to use their L2 in speaking classes and believe that L2 should be the prior language in general speaking classes. More than two-thirds of the respondents prefer to use L2 when they want to communicate with each other inside and outside of the classroom and prefer to use L2 in doing their assignments or performing orally in class. More than half of the respondents prefer to use L2 in assessment sessions.

Psychometric properties of the mental health continuum-short form in Iranian adolescents.

Psychological tests are necessary to assess the mental state of individuals. Mental health is one of the important psychological indicators and is increasingly considered as having various aspects of well-being. The Mental Health Continuum-Short Form (MHC-SF) is a 14-item instrument that assesses mental health, focusing on emotional, psychological, and social well-being. The present study, the psychometric properties of the Persian version of the MHC-SF were examined in relation to its factor structure, internal consistency, construct validity, and gender measurement invariance among adolescents. The population of this study was Iranian adolescents between 11-and 18-year-old who were enrolled in the seventh to twelfth grades. A convenience sample of 822 Adolescents from four large cities in the Iran (Tehran, Zanjan, Hamedan and Ghazvin) participated in the present study. Questionnaires were completed online. Statistical analyses to evaluate the factor structure, internal consistency, construct validity, gender and age factorial invariance were performed in SPSS and LISREL. According to the results of confirmatory factor analysis, the MHC-SF is composed of three factors: emotional, psychological, and social well-being. Reliability was confirmed by Cronbach's alpha method and composite reliability (>0.7). Measurement invariance were confirmed among girls and boys. Convergent and divergent validity were also evaluated and confirmed by correlating the test score with similar and different tests. This study confirmed the psychometric properties of MHC-SF in the Iranian adolescent community. This instrument can be used in psychological research and diagnostic evaluations.

A Comparison of Preference-Based, Generic and Disease-Specific Health-Related Quality of Life in Pediatric Inflammatory Bowel Disease.

Generic preference-based HRQOL assessments used expressly for economic evaluation have not been examined in pediatric Crohn's disease (CD) and ulcerative colitis (UC). The objective was to further assess the construct validity of preference-based HRQOL measures in pediatric IBD by comparing the Child Health Utility 9 Dimensions (CHU9D) and Health Utilities Index (HUI) to the disease-specific IMPACT-III and to the generic PedsQL in children with CD and with UC. The CHU9D, HUI, IMPACT-III and/or PedsQL were administered to Canadian children aged 6 to 18 years with CD and UC. CHU9D total and domain utilities were calculated using adult and youth tariffs. HUI total and attribute utilities were determined for the HUI2 and HUI3. Total scores for IMPACT-III and PedsQL were determined. Spearman correlations were calculated between generic preference-based utilities and the IMPACT-III and PedsQL scores. The questionnaires were administered to 157 children with CD and 73 children with UC. Moderate to strong correlations were observed between the CHU9D, HUI2, HUI3 and the disease-specific IMPACT-III or generic PedsQL. As hypothesized, domains with similar constructs demonstrated stronger correlations, such as the Pain and Well-being domains. While all questionnaires were moderately correlated with the IMPACT-III and PedsQL questionnaires, the CHU9D using youth tariffs and the HUI3 were most strongly correlated and would be suitable choices to generate health utilities for children with CD or UC for the purpose of economic evaluation of treatments in pediatric IBD.

Translation and Validation of Maternal Confidence Questionnaire (MCQ) In Iran: Persian Version

ABSTRACT Objective Mother's confidence is defined as the understanding of the mother of her ability to take care of the child and knowing his/her needs. The Maternal Confidence Questionnaire (MCQ) is designed to measure a mother's confidence in a neonatal intensive care unit (NICU). The aim of this study was to validate a Persian version of the MCQ for Iranian mothers. Design The MCQ was translated into Persian using a forward–backward method. Validity was assessed using face, content, and construct validity measures. Results Based on the result of face validity, all items of the scale are appropriate, clear and relevant for using. Bartlett's test (KMO = 0.92, PV<0.001) demonstrates the appropriateness of using factor analysis for our data set. Also, 53% of total variance has been explained by one-factor CFA model that confirmed by goodness of fit indices; GFI = 0.96, CFI = 0.93, RMSEA = 0.07 (0.05, 0.09) as well as p-close = 0.040 and the CMIN = 2.2, p<0.001. The scale has excellent internal consistency (Cronbach's alpha = 0.93). Conclusion The Persian version of MCQ showed adequate reliability and validity for measuring maternal confidence in Iranian mothers. This instrument can be used in future studies to assess confidence in mothers with preterm neonates in Iran. Also, this instrument will help neonatal nurses and medical staff to measure confidence in mothers with preterm neonates and accordingly provide supportive interventions.

Good, bad, and beyond: Perils of partialing positive and negative couple variables within individuals.

Partialing correlated predictors to test independent effects is an essential tool in couple research. In actor-partner models, partners' parallel scores are partialed in tests of unique associations with outcomes. Correlated aspects of couple functioning are also often partialed within individuals to examine separate effects. Partialed versions of measures are typically interpreted as assessing the same construct as original unadjusted variables, but in fact their meaning can change. Extending a prior report on changes in construct validity resulting from partialing partners' parallel scores, the present analyses examined effects of partialing measures of positive and negative relationship variables within individuals, specifically perceived support from the partner and relationship conflict. In 300 middle-aged and older couples, we utilized participants' interpersonal circumplex ratings of their partner's typical behavior during marital interactions to compare interpersonal correlates of unadjusted and within-person partialed forms of the Quality of Relationships Inventory Support and Conflict scales. Compared to unadjusted scores, partialed support scores (i.e., adjusted for conflict) were substantially less closely associated with ratings of partner's warmth, and were associated with a less submissive (i.e., less agreeable, cooperative) form of warmth. Compared to unadjusted scores, partialed conflict scores (i.e., adjusted for support) were substantially less closely correlated with ratings of the partner's hostility, and were associated with a more controlling (i.e., critical, coercive) form of hostility. Results were nearly identical for wives and husbands. Partialing correlated scores within individuals can alter the construct validity of relationship measures, suggesting the need for careful reporting and interpretation in couple research.

Consistency among common measures of corporate social and sustainability performance

The objective of this study is to thoroughly evaluate and compare three popular databases used in research on the environment, society and governance. Our analysis aims to establish construct validity, and thus addresses the difficulty in choosing which data providers to use for this type of research, and whether findings are comparable across the three databases and applicable to firms in different countries. The most widely used database, referred to as KLD (Kinder, Lydenberg, and Domini), is used to help establish the construct validity of measures coming from the other databases, known as Sustainalytics and Asset4. Frequently used measures from the three databases are highly correlated, and tests of the relationships between composite measures from the databases and financial performance are consistently positive. Even a more focused stakeholder management measure doesn't materially alter the results, suggesting that stakeholder-oriented firms also tend to be socially responsible in ways beyond stakeholder relationships, such as in preserving the environment. We also find that Sustainalytics and Asset4 track substantially more variables and contain many more international firms than KLD, making them more flexible for empirical work on this topic.

The Utility of Natural Language Samples for Assessing Communication and Language in Infants Referred with Early Signs of Autism.

Natural Language Sampling (NLS) offers clear potential for communication and language assessment, where other data might be difficult to interpret. We leveraged existing primary data for 18-month-olds showing early signs of autism, to examine the reliability and concurrent construct validity of NLS-derived measures coded from video-of child language, parent linguistic input, and dyadic balance of communicative interaction-against standardised assessment scores. Using Systematic Analysis of Language Transcripts (SALT) software and coding conventions, masked coders achieved good-to-excellent inter-rater agreement across all measures. Associations across concurrent measures of analogous constructs suggested strong validity of NLS applied to 6-min videoclips. NLS offers benefits of feasibility and adaptability for validly quantifying emerging skills, and potential for standardisation for clinical use and rigorous research design.

Electromagnetic and climatic foundations of human aggression

Heat is associated with human aggression in field research, assumedly by affecting emotions, but it is not in laboratory experiments. Since this may be so because temperature functions as a proxy for UV radiation in field settings, not in the laboratory, this research tested, across 126 countries, whether temperature loses its predictive capacity when the electromagnetic variable is controlled. Temperature presented null statistical effects when UV radiation was controlled, although it exhibited a tangential contribution in mediation analyses. The results revealed strong direct effects of UV radiation on Van de Vliert and Daan's (2017) aggression composite scores, and strong indirect effects on homicide rate. Economic inequality emerged as a strong mediator related to homicide rate, not to the aggression composite, while steady rain, pathogen prevalence, per capita income and cognitive performance contributed to the explanation of human aggression. These findings suggest that the heat-aggression paradigm has outlived its usefulness and that global warming should not be expected to increase aggression via emotions. Future studies must address UV radiation's effects across routine activity patterns, strengthen the construct validity of measures of aggression, target omitted variables, and confirm the theorized role of testosterone as a mediator using field and, especially, laboratory studies.

Psychometric properties of the Arabic version of Physical Activity Questionnaire for Adolescents (PAQ-A)

AimTo evaluate the psychometric properties of the Arabic version of the Physical Activity Questionnaire for Adolescents (PAQ-A). BackgroundPhysical inactivity is a major risk factor for becoming overweight or obese and developing chronic conditions that lead to an increase in mortality globally. Inadequate physical activity (PA) has been a problem among Arabic-speaking populations, including female adolescents in Saudi Arabia. Unfortunately, psychometrically sound measures to assess PA among female adolescents in Saudi Arabia are lacking, indicating that a reliable, valid and feasible self-report measure is urgently needed for use with this young Arabic-speaking population. MethodsA cross-sectional study approved by a university institutional review board was conducted with 383 Saudi female adolescents, 13–18 years of age, who were recruited from 10 all-female public schools in Jeddah, Saudi Arabia. Physical activity was measured via the PAQ-A, which assesses the level of PA engagement during the school year for 7 days. Internal consistency was estimated. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to assess the measure's construct validity and the Pearson correlation coefficient was used to assess convergent validity. ResultsCronbach's alpha was 0.81, indicating acceptable internal consistency. Item-total correlation coefficients ranged from 0.11 to 0.61. Both EFA and CFA indicated a single-factor. The scale was significantly correlated with other cognitive and affective variables that reflected the physical activity perceptions among the female adolescents, such as enjoyment of PA, PA self-efficacy and social support for PA. ConclusionsThe Arabic version of the PAQ-A is reliable and valid measure for assessing PA among Arabic-speaking female adolescents.

Portuguese Physical Literacy Assessment - Observation (PPLA-O) for adolescents (15-18 years) from grades 10-12: Development and initial validation through item response theory.

Aims of these studies were to develop the Portuguese Physical Literacy Assessment Observation instrument (PPLA-O) to assess the physical and part of the cognitive domain of Physical Literacy (PL) through data collected routinely by Physical Education (PE) teachers; and to assess the construct validity (dimensionality, measurement invariance, and convergent and discriminant validity) and score reliability of one of its modules [Movement Competence, Rules, and Tactics (MCRT)]. Content analysis of the Portuguese PE syllabus and literature review were used for PPLA-O domain identification. Multidimensional Item Response Theory (MIRT) models were used to assess construct validity and reliability, along with bivariate correlations in a sample of 515 Portuguese grade 10-12 students (M age = 16, SD = 1). PPLA-O development resulted in an instrument with two modules: MCRT (22 physical activities) and Health-Related Fitness (HRF; 5 protocols); both assessed with teacher-reported data entered in a spreadsheet. A two correlated dimensions Graded Response Model (Manipulative-based Activities [MA], and Stability-based Activities [SA]) showed best fit to the MCRT data, suggesting measurement invariance across sexes, and adequate to good score reliabilities (MA = .89, and SA = .73). There was a moderate to high correlation (r = .68) between dimensions, and boys had higher scores in both dimensions. Correlations among MCRT scores and HRF variables were similar in magnitude to previous reports in meta-analysis and systematic reviews. PPLA-O is composed of two modules that integrate observational data collected by PE teachers into a common frame of criterion-referenced PL assessment. The HRF module uses data collected through widely validated FITescola® assessment protocols. The MCRT makes use of teacher-reported data collected in a wide range of activities and movement pursuits to measure movement competence and inherent cognitive skills (Tactics and Rules). We also gathered initial evidence supporting construct validity and score reliability of the MCRT module. This highly feasible instrument can provide Portuguese grade 10-12 (15-18 years) PE students with feedback on their PL journey, along with the other instrument of PPLA (PPLA-Questionnaire). Further studies should assess inter and intra-rater reliability and criterion-related validity of its two modules.
