Game Awareness: A Questionnaire

This paper deals with one of the possible methodological approaches to an empirical examination of game awareness. Such an outline should enable the gathering of a deeper understanding of individuals’ awareness. The questionnaire is based on a scenario technique, and it is focused on game awareness in situations with possible strategic interactions. The goal is to assess the instrument regarding its reliability and validity. Internal reliability is assessed using Cronbach’s alpha coefficient. A k-nn analysis was used to estimate divergent construct validity and criterion validity, and nonparametric factor analysis was used to estimate convergent construct validity. The questionnaire satisfies the requirements of reliability and validity. Moreover, there is an indication that each of the eight scenarios may be used separately, as they also meet the criteria for reliability and validity. Possible practical and theoretical implications involve questionnaire use as a basis for educational intervention, other instruments’ development, as well as for the collection and publication of behavioral insights about game awareness. Behavioral insights should enrich the theory and incite behavioral game theory models of game awareness and its implications.

Use of the PROMIS Mobility score in assessing function in adolescents and adults previously affected by childhood hip disease

Aims The Patient-Reported Outcomes Measurement Information System (PROMIS) has demonstrated faster administration, lower burden of data capture and reduced floor and ceiling effects compared to traditional Patient Reported Outcomes Measurements (PROMs). We investigated the suitability of PROMIS Mobility score in assessing physical function in the sequelae of childhood hip disease. Methods In all, 266 adolscents (aged ≥ 12 years) and adults were identified with a prior diagnosis of childhood hip disease (either Perthes’ disease (n = 232 (87.2%)) or Slipped Capital Femoral Epiphysis (n = 34 (12.8%)) with a mean age of 27.73 years (SD 12.24). Participants completed the PROMIS Mobility Computer Adaptive Test, the Non-Arthritic Hip Score (NAHS), EuroQol five-dimension five-level questionnaire, and the Numeric Pain Rating Scale. We investigated the correlation between the PROMIS Mobility and other tools to assess use in this population and any clustering of outcome scores. Results There was a strong correlation between the PROMIS Mobility and other established PROMs; NAHS ( rs = 0.79; p < 0.001). There was notable clustering in PROMIS at the upper end of the distribution score (42.5%), with less seen in the NAHS (20.3%). However, the clustering was broadly similar between PROMIS Mobility and the comparable domains of the NAHS; function (53.6%), and activity (35.0%). Conclusion PROMIS Mobility strongly correlated with other tools demonstrating convergent construct validity. There was clustering of physical function scores at the upper end of the distributions, which may reflect truncation of the data caused by participants having excellent outcomes. There were elements of disease not captured within PROMIS Mobility alone, and difficulties in differentiating those with the highest levels of function.

Cross-cultural adaptation, validity, and reliability of the Neck OutcOme Score (NOOS-Ar) among the Saudi Arabian populace

BACKGROUND: To date the Neck OutcOme Score (NOOS) was not cross-culturally adapted, validated or available in the Arabic language, although it was available in other languages. OBJECTIVE: To translate and cross-culturally adapt the Arabic version of the Neck OutcOme Score (NOOS-Ar) and study its psychometric properties. METHODS: A sample of 146 subjects with chronic neck pain filled in the NOOS-Ar questionnaire to determine the Cronbach’s alpha (α) for internal consistency, test-retest reliability by intraclass correlation coefficients(2,1) [ICC(2,1)], inter-item correlation, measurement error by coefficient of variance and minimal detectable change, ceiling and floor effects, convergent construct validity with visual analog scale (VAS) by Spearman’s rank correlation coefficient (ρ) and factor analysis to calculate and determine its psychometric properties. RESULTS: Excellent internal consistency (Cronbach’s α> 0.9) and test-retest reliability [ICC(2,1)> 0.9] were observed in NOOS-Ar. None of the five subscales of the NOOS-Ar showed a floor or ceiling effect. The coefficient of variance was generally high, but the minimal detectable change was within the acceptable range (< 30%). The ‘everyday activity and pain’ and ‘symptoms’ subscales of the NOOS-Ar, showed a moderate correlation with VAS. CONCLUSION: The NOOS-Ar is highly reliable and has a moderate to good degree of convergent construct validity with VAS with no floor or ceiling effects.

Psychometric Properties of the Generalized Pliance Questionnaire in Spain

Rule-governed behavior is a central concept to explain complex human behavior from a functional-analytic standpoint. Recently, a self-report measure of a functional type of rule-following called generalized pliance has been developed – the Generalized Pliance Questionnaire (GPQ). The GPQ has two versions with 18 and 9 items, respectively. This study aimed to analyze the factor structure and psychometric properties of both GPQ versions in a Spanish online sample ( N = 846). Confirmatory factor analyses showed that the one-factor model obtained an acceptable fit in the GPQ-18, but an inadequate fit in the GPQ-9. The GPQ-18 showed measurement invariance across gender, excellent internal consistency, and convergent construct validity. According to the results, the GPQ-18 showed good psychometric properties in Spanish samples.

Psychometric properties of the Automatic Thoughts Questionnaire-8 in two Spanish nonclinical samples

Background The ATQ is a widely used instrument consisting of 30 items that assess the frequency of negative automatic thoughts. However, the extensive length of the ATQ could compromise its measurement efficiency in survey research. Consequently, an 8-item shortened version of the ATQ has been developed. This study aims to analyze the validity of the ATQ-8 in two Spanish samples. Method The ATQ-8 was administered to a total sample of 1,148 participants (302 undergraduates and 846 general online population). To analyze convergent construct validity, the questionnaire package also included the Dysfunctional Attitude Scale-Revised (DAS-R), Depression Anxiety and Stress Scale-21 (DASS-21), Acceptance Action Questionnaire-II (AAQ-II), Cognitive Fusion Questionnaire (CFQ), Generalized Pliance Questionnaire (GPQ), and Satisfaction with Life Scale (SWLS). To analyze internal consistency, we computed Cronbach’s alpha and McDonald’s omega. A confirmatory factor analysis was conducted to test the one-factor structure of the ATQ-8. In so doing, a robust diagonally weighted least square estimation method (Robust DWLS) was adopted using polychoric correlations. Afterward, we analyzed measurement invariance across samples, gender, groupage, and education level. Lastly, we evaluated convergent construct validity by computing Pearson correlations between the ATQ-8 and the remaining instruments. Results The internal consistency across samples was adequate (alpha and omega = .89). The one-factor model demonstrated a good fit to the data (RMSEA = 0.10, 90% CI [0.089, 0.112], CFI = 0.98, NNFI = 0.97, and SRMR = 0.048). The ATQ-8 showed scalar metric invariance across samples, gender, groupage, and education level. The ATQ-8 scores were significantly associated with emotional symptoms (DASS-21), satisfaction with life (SWLS), dysfunctional schemas (DAS-R), cognitive fusion (CFQ), experiential avoidance (AAQ-II), and generalized pliance (GPQ). In conclusion, the Spanish version of the ATQ-8 demonstrated adequate psychometric properties in Spanish samples.

Translation and Cross-Cultural Adaptation of the Harris Hip Score into Arabic

Background: The Harris Hip Score (HHS) is a widely used Patient-Related Outcomes score. It measures pain and function levels in patients with hip pathologies. Objectives: The main objective of this study is to translate and culturally adapt the HHS into Arabic, and to assess the reliability and validity of the translated version. Material & Methods: 110 patients participated in this survey. The internal consistency tests were calculated using Cronbach’s alpha. Test-retest reliability (intra-correlation coefficient), convergent construct validity, convergent validity, floor & ceiling effects, and responsiveness were calculated. Bland-Altman Plot and forest plots were done to measure the level of agreement. Results: Test reliability for the first testing situation - calculated using Cronbach's alpha - was 0.98 for the pain subscale, 0.98 for the stiffness, and 0.99 for the physical function subscale. For the second testing, reliability was 0.99, 0.97, and 0.99 (pain, stiffness, and physical function, respectively).

Questionnaire measuring patient participation in health care: Scale development and psychometric evaluation

Background: Patient participation in treatment and care is often encouraged and is desirable because of its proven positive impact on treatment, quality of care and patient safety. Aims: To develop an instrument to measure patient participation in health care and to investigate the measurement properties of the Patient Participation Questionnaire (PPQ). Methods: A literature review was conducted to develop a model of patient participation. The PPQ was constructed consisting of 17 items organized into four subscales. Psychometric evaluation of factor structure, convergent construct validity by hypothesis testing and analyses of internal consistency using Cronbach’s alpha were performed on data from a hospitalised mixed group of patients with cardiac disease, pulmonary disease and cancer ( N=378 patients). Results: Confirmatory factor analysis did not show a clear model fit, which is why an exploratory factor analysis was performed, suggesting a different four subscale structure consisting of a total of 16 items. The four subscales were labelled Shared decision power, Adapted and individualized knowledge, Collaboration and Human approach. There were strong ceiling effects on all items. Analysis of convergent construct validity showed a moderate correlation (0.59) between the PPQ and another instrument measuring patient participation. Internal consistency for the total PPQ score was high: 0.89. Conclusion: In a mixed group of patients with cardiac disease, pulmonary disease and cancer, the PPQ showed promising psychometric properties in terms of factor structure, convergent construct validity and internal consistency. The PPQ may be used to shed light on the experience of patient participation and guide quality improvements.

Psychometric properties of women’s satisfaction with the childbirth education class questionnaire for Iranian population

Background: Childbirth preparation classes can reduce pregnant women’s anxiety and fear levels by providing them with training supports. The importance of mothers’ participation in these classes, evaluation of their satisfaction with these classes, and lack of a standard instrument in Iran led to the necessity of conducting this study for the translation and psychometric analysis of the women’s satisfaction with the childbirth education class questionnaire for the population of Iranian women. Methods: The questionnaire was translated from English into Persian through the forward-backward translation method. The cluster sampling method was employed to select 205 pregnant women with gestational age of 35-37 weeks from all health complexes of Tabriz, Iran. The face, content, and construct validity of the research instrument were assessed through exploratory and confirmatory factor analyses. Internal consistency and test-retest reliability were measured to evaluate the overall reliability of the questionnaire. Results: The impact scores of all items were above 1.5. The content validity index (CVI) and content validity ratio (CVR) of the questionnaire were 0.88 and 0.94, respectively. The convergent construct validity of the whole questionnaire and those of its three subscales were confirmed through the exploratory factor analysis (EFA). The factor loadings of no items were below 0.3, and the X2⁄df ratio was smaller than 5. In addition, the RMSEA was smaller than 0.08; therefore, the overall model validity was confirmed. Cronbach’s alpha and intra-class correlation coefficient (ICC) were 0.93 and 0.96, respectively, indicating the acceptable reliability of the questionnaire. Conclusion: The Persian version of this questionnaire, entitled "Women’s Satisfaction with Childbirth Education Class" is a valid and reliable instrument for measuring Iranian women’s satisfaction with childbirth education classes.

ANALYTICAL CONSIDERATIONS OF DEVELOPING A PHENOTYPIC AGING MEASURE: THE CONCEPTUAL FRAMEWORK MUST COME FIRST!

We propose a latent structural model framework where phenotypic aging is a latent variable influenced by chronological age, genes and environment. Within this framework, phenotypic age influences aging-related outcomes and is reflected by latent domains of aging (body composition, energetics, homeostasis, and neural functioning) reflected by biomarkers. First, we validate the framework by selecting age-associated domain-specific biomarkers and assessing internal consistency and convergent construct validity (Cronbach’s alpha). Using data from the Baltimore Longitudinal Study of Aging, within-domain Cronbach’s alphas ranged from 0.80 to 0.92, supporting convergent construct validity. Second, we evaluate two broad methods for combining biomarkers into one phenotypic age measure customized to different objectives: 1) confirmatory factor analysis of chronological age-adjusted biomarkers to create a measure to identify pleiotropic genetic and environmental mechanisms, and 2) machine-learning methods to create a measure optimizing predictive and concurrent criterion validity. This framework will enable evaluation of candidate biological mechanisms of aging.
