Propiedades Psicométricas del Inventario Psicológico de Ejecución Deportiva (IPED) en deportistas peruanos de Alto Rendimiento

To measure athlete's success and his sports performance, it is required to quantify the maximum performance developed during seasons of trainings and championships; using a valid, reliable, and adapted to peruvian context instrument. However, caution is urged when considering there is no psychometric evidence to support the use of any scale related to peruvian high performance athletes' sample. The current study was designed to evaluate the psychometric properties of the Sports Performance Psychological Inventory (IPED) in the mentioned sample. Method: Participated 255 peruvian athletes with ages between 14 and 38 years (N:23; SD: 4.29); who actively represents the country and in sports modalities affiliated with the Peruvian Sports Institute (IPD). For the collection of information, a sociodemographic record, Sports Performance Psychological Inventory (IPED) and the Mental Toughness Questionnaire (MTQ) were used. Results: IPED model demonstrated, that the seven-dimensional model had an acceptable fit (SBx2 = 2243.096 / df = 798; CFI=. 955; SRMR=. 095; RMSEA=. 084 [IC90%:. 080 -. 069] and reliability analyses revealed high internal consistency (ω =. 841 > ω =. 754). In addition, scores correlated positively between IPP and MTQ dimensions (AC=. 678; CAN=. 557; CAT=. 457; CVI=. 328; NM=. 425; CAP=. 641; CAC=. 662) and Control (AC=. 558; CAN=. 733; CAT=. 682; CVI=. 171; NM=. 272; CAP=. 432; CAC=. 563) Conclusion: The IPED provides adequate evidence of validity and reliability to measure sports performanc

Body dissatisfaction in university women: new psychometric evidence from the 14-item Body Shape Questionnaire (BSQ-14)

In recent years, young university students have experienced a greater concern for the body aspect that is related to having a slim figure. In this sense, it is important to have tools to measure the dissatisfaction they may have with their body appearance. The objective of the study was to evaluate the psychometric properties of the Body Shape Questionnaire (BSQ-14). Specifically, to evaluate the internal structure of the BSQ-14, the internal consistency of the model, the evidence of discriminant validity based on the correlations of the average score of the BSQ-14 with a measure of mindfulness and the invariance of the BSQ-14 model, considering the variable of performance of physical activities. For hundred two young university students from Metropolitan Lima participated, with an average age of 20.05 years (SD = 18.18). A test battery including the BSQ-14 and Mindful Attention Awareness Scale (MASS-5) was administered. The results indicate that the one-dimensional structure of the BSQ-14 presented a good fit (x2 = 571,420; CFI = 0.962; SRMR = 0.051) and adequate reliability by the internal consistency method (ω = 0.962). Likewise, the BSQ-14 showed negative correlations with Mindfulness and body satisfaction. The BSQ-14 was shown to be invariant among university women who do or do not exercise. It is concluded that the study provides results that support the use of the BSQ-14 to measure body dissatisfaction with evidence of validity and reliability in a sample of young university students. of Metropolitan Lima

Assessment of Fear of COVID-19 in Older Adults: Validation of the Fear of COVID-19 Scale

There is no information in Peru on the prevalence of mental health problems associated with COVID-19 in older adults. In this sense, the aim of the study was to gather evidence on the factor structure, criterion-related validity, and reliability of the Spanish version of the Fear of COVID-19 Scale (FCV-19S) in this population. The participants were 400 older adults (mean age = 68.04, SD = 6.41), who were administered the Fear of COVID-19 Scale, Revised Mental Health Inventory-5, Patient Health Questionnaire-2 items, and Generalized Anxiety Disorder Scale 2 items. Structural equation models were estimated, specifically confirmatory factor analysis (CFA), bifactor CFA, and structural models with latent variables (SEM). Internal consistency was estimated with composite reliability indexes (CRI) and omega coefficients. A bifactor model with both a general factor underlying all items plus a specific factor underlying items 1, 2, 4, and 5 representing the emotional response to COVID better represents the factor structure of the scale. This structure had adequate fit and good reliability, and additionally fear of COVID had a large effect on mental health. In general, women had more fear than men, having more information on COVID was associated to more fear, while having family or friends affected by COVID did not related to fear of the virus. The Spanish version of the Fear of COVID-19 Scale presents evidence of validity and reliability to assess fear of COVID-19 in the Peruvian older adult population

Validity and invariance of measurement of the satisfaction with love life scale in older adults

In recent years, interest in satisfaction with love life (SWLL) has increased. Empirical evidence demonstrated that SWLL favors subjective well-being, physical and mental health, marital quality and stability. In this regard, the study aimed to examine evidence based on the internal structure validity, reliability, and measurement invariance of the Peruvian version of the Satisfaction with Love Life Scale (SWLLS). The participants were 323 older adults recruited from the region of San Martin (Peru) with an average age of 68.73 years (SD = 7.17). The sample comprised of 49.5% women and 50.5% men. The results supported the one-dimensional model and adequate reliability of the SWLLS. A multi-group analysis provided evidence of configural, metric, and scale invariance across genders. The findings verified the validity and reliability of the Peruvian version of the SWLLS, which can be used to measure SWLL.Universidad del Nort

Measurement Invariance of the Short UCLA Loneliness Scale in Spanish and Peruvian Old People: Latent Mean Differences and Evidence for Differential Effects on Perceived Health

The objectives of this study are to evaluate the measurement invariance of the University of California Los Angeles Loneliness Scale (UCLA-LS) three-item version (UCLA-LS-3) in older adults in Peru and Spain, to compare the latent means of loneliness, and to evaluate the psychometric properties of the scale with Item Response Theory (IRT) models, and evaluate the possible moderating effects of the country on loneliness-health relationships. Peruvian sample was composed of 235 old adults from the city of Lima. The Spanish sample was composed of 443 old adults. The three-factor structure of RUCLA-3 anchored to the health measure fitted the data reasonably well in Spain and Peru. The R-UCLA-3 may be considered invariant for these two samples. The latent means of loneliness are different, the Peruvian average of loneliness being greater than that of Spain. The R-UCLA-3 is an invariant measure in older adults in Peru and Spain, with adequate psychometric properties through IRT models

Sociodemographic and psychological predictors of intention to receive a COVID-19 vaccine in elderly peruvians

The implementation of a vaccine against COVID-19 is one of the most important health strategies to mitigate the spread of the disease. The objective of this study was to estimate the prevalence of the intention to be vaccinated against COVID-19 and its predictors in older Peruvian adults. This is a cross-sectional study, where information was collected through an online survey regarding vaccination intention of the participants, as well as sociodemographic and psychological variables. A multiple regression analysis was applied to identify predictors of intention to be vaccinated against COVID-19. We evaluated 245 participants, who had a mean age of 72.74 years old (SD = 6.66). 65.5% of these older adults expressed a high likelihood of accepting vaccination, while 20.9% expressed a low likelihood of accepting vaccination, and 13.6% were hesitant. Eleven predictors were identified that explained 66.69% of the intention to vaccinate against COVID-19. This identified place of residence, perceived likelihood of contracting COVID-19, severity of previous infection with COVID-19, fear of the disease, previous refusal of a vaccine, concerns about vaccine sales and speculation, and trust toward vaccines against COVID-19, as the main predictors. Our results show that confidence in vaccines and previous vaccine refusal are relevant predictors of intention to vaccinate against COVID-19 in older adults; these findings may be useful to guide the development of campaigns for the immunization of this vulnerable group in the current pandemic. © 2021, Associação Brasileira de Psicologia

COVID-19 anxiety, psychological well-being and preventive behaviors during the COVID-19 pandemic in Latin America and the Caribbean: relationships and explanatory model

This study assesses the relationship between COVID-19 anxiety and subjective well-being in terms of the mediating role of COVID-19 preventive behaviors. Additionally, the contribution of sociodemographic factors (sex and age) and risk perception on COVID-19 anxiety and its potential measurement invariance was tested in 5655 participants from 12 countries in Latin America and the Caribbean. A mixture of both latent and observable variables were analyzed using a system of structural equations. The Coronavirus Anxiety Scale (CAS), Preventive COVID-19 Infection Behaviors Scale (PCIBS) and single-item measures were used to assess the perceived probability of death, perceived severity and concern about transmitting COVID-19. The results indicated that there is a significant and relevant direct effect of COVID-19 anxiety on participants' well-being. Furthermore, COVID-19 anxiety significantly predicted both preventive behavior (β =.29, p <.01) and well-being (β = –.32, p <.01). The effects of COVID anxiety and preventive behavior explained 9.8% of the variance in well-being (R-square =.098); whereas, 8.4% of the variance in preventive behavior was associated with COVID anxiety (R-square =.084). Likewise, perceived likelihood of death from COVID, perceived severity of COVID, and concerns about COVID transmission were positively related to anxiety. Age was negatively related to anxiety, with men being less anxious than women. The results are invariant by country, i.e., the broad relationships found in the combined sample are also present in each individual country. The findings indicate that, although the exact relationships between variables may vary between countries, there are enough similarities to provide useful information about the impact of the COVID-19 pandemic in each of the countries included in the study

Studies of new Higgs boson interactions through nonresonant HH production in the b¯bγγ fnal state in pp collisions at √s = 13 TeV with the ATLAS detector

A search for nonresonant Higgs boson pair production in the b ¯bγγ fnal state is performed using 140 fb−1 of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. This analysis supersedes and expands upon the previous nonresonant ATLAS results in this fnal state based on the same data sample. The analysis strategy is optimised to probe anomalous values not only of the Higgs (H) boson self-coupling modifer κλ but also of the quartic HHV V (V = W, Z) coupling modifer κ2V . No signifcant excess above the expected background from Standard Model processes is observed. An observed upper limit µHH &lt; 4.0 is set at 95% confdence level on the Higgs boson pair production cross-section normalised to its Standard Model prediction. The 95% confdence intervals for the coupling modifers are −1.4 &lt; κλ &lt; 6.9 and −0.5 &lt; κ2V &lt; 2.7, assuming all other Higgs boson couplings except the one under study are fxed to the Standard Model predictions. The results are interpreted in the Standard Model efective feld theory and Higgs efective feld theory frameworks in terms of constraints on the couplings of anomalous Higgs boson (self-)interactions
