Item type:Publication, Quantifying trunk neuromuscular control using seated balancing and stability threshold(Elsevier, 2020-11-09)Performance during seated balancing is often used to assess trunk neuromuscular control, including evaluating impairments in back pain populations. Balancing in less challenging environments allows for flexibility in control, which may not depend on health status but instead may reflect personal preferences. To make assessment less ambiguous, trunk neuromuscular control should be maximally challenged. Thirty-four healthy subjects balanced on a robotic seat capable of adjusting rotational stiffness. Subjects balanced while rotational stiffness was gradually reduced. The rotational stiffness at which subjects could no longer maintain balance, defined as critical stiffness (kCrit), was used to quantify the subjects’ trunk neuromuscular control. A higher kCrit reflects poorer control, as subjects require a more stable base to balance. Subjects were tested on three days separated by 24 hours to assess test–retest reliability. Anthropometric (height and weight) and demographic (age and sex) influences on kCrit and its reliability were assessed. Height and age did not affect kCrit; whereas, being heavier (p < 0.001) and female (p = 0.042) significantly increased kCrit. Reliability was also affected by anthropometric and demographic factors, highlighting the potential problem of inflated reliability estimates from non-control related attributes. kCrit measurements appear reliable even after removing anthropometric and demographic influences, with adjusted correlations of 0.612 (95%CI: 0.433–0.766) versus unadjusted correlations of 0.880 (95%CI: 0.797–0.932). Besides assessment, trainers and therapists prescribing exercise could use the seated balance task and kCrit to precisely set difficulty level to a percentage of the subject's stability threshold to optimize improvements in trunk neuromuscular control and spine health. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Validity and reliability of the Parental Involvement Scale: caregiving and socialization activities in Peruvian parents(Universidad Catolica de Colombia, 2022-06-22)El presente estudio busca obtener evidencias de validez y confiabilidad de la Escala de Involucramiento Parental: Actividades de cuidado y socialización en una muestra de padres peruanos de niños y niñas preescolares. Para ello, se realizó una traducción y armonización del lenguaje del instrumento a partir de su versión en inglés al español, para luego aplicar la nueva versión a un grupo de 420 padres y 420 madres de niños y niñas de cinco ciudades. La evidencia de la estructura interna se evaluó a través de un análisis factorial confirmatorio multigrupo, utilizando el método de máxima verosimilitud para examinar la estructura de los 26 ítems originales. Durante el análisis, se procedió a la eliminación progresiva de los ítems con bajas cargas factoriales hasta encontrar un modelo con adecuados indicadores de ajuste [χ2 (531) = 822.82; p < .001; χ2 /gl = 1.550; gfi = .90; cfi = .95; tli = .94; rmsea = .036, ic 90 % = (.031-.041), p close = 1.000, srmr = .05]. El resultado fue una escala de 18 ítems distribuidos en las cinco dimensiones originales, cada una con confiabilidad por consistencia interna alfa de Cronbach entre .66 y .78 y coeficientes omega entre .70 y .75. La confiabilidad entre evaluadores estuvo entre .67 y .88. Los alcances y limitaciones del estudio son discutidos teniendo en cuenta la importancia de contar con instrumentos de medición del involucramiento paterno, relativo al materno, que consideren las perspectivas de padres y madres en el contexto peruano. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Validation of the Spanish version of the Baby Pediatric Symptom Checklist (BPSC) with Peruvian infants aged 6 to 18 months from socioeconomically vulnerable settings(Aitana Research Group, 2024-09-01)Validation of the Spanish version of the Baby Pediatric Symptom Checklist (BPSC) with Peruvian infants aged 6 to 18 months from socioeconomically vulnerable settings. Difficulties in the socioemotional development of infants are associated with problems of adaptation to the social environment and greater probability of psychopathology during childhood, adolescence, and adulthood. Despite this, in the Latin American context there is no instrument available to assess such difficulties with infants, specially in socioeconomically vulnerable contexts. Therefore, the aim of this study was to obtain evidence of internal validity of the Spanish versión of the Baby Pediatric Symptom Checklist (BPSC; Sheldrick et al., 2013) in a sample of 1239 infants (50% females and 50% males) aged six to 18 months (M = 12.40, SD = 3.20). The infants came from urban and rural areas of Peru with high rates of socioeconomic vulnerability. In the overall sample, the exploratory factor analysis (KMO = .93, Bartlett’s Sphericity Test [66] = 28960.62, p < .001) and confirmatory factor analysis (χ2(51) = 254.58, p < .001, CFI = .97, RMSEA = .06 and SRMR = .03) results showed adequate internal structure validity with a three-factor solution which shows an appropriate reliability (α = .82-.84; ω = .81 - .87). In addition, the results of the analyses performed through exploratory factor analysis by age groups also revealed an adequate functioning of the scale in the 6- to 12-month and 12- to 18-month age groups.Thus, evidence is provided to support the use of the BPSC in studies conducted in Peru. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Psychometric Analysis of a Brief Measure of Emotional Intelligence (EQ-i-M20) in Teenagers from Lima(AIDEP, 2023-01-01)The research aimed to assess if the EQ-i-M20 presents evidence of validity regarding its internal structure, measurement invariance between men and women, and acceptable reliability. The sample consisted of 788 adolescents between 11 and 18 years old from an educational institution in Lima (Peru). The internal structure was evaluated by the Exploratory Structural Equation Modeling (ESEM), both the oblique model and the bifactor, the invariance of measurement with a multiple ESEM group, and its reliability using the α and ω. The results indicate that in men and women. the original factor structure of five oblique factors is replicated, that it has an acceptable degree of measurement invariance, and the reliability values are satisfactory. In conclusion, the EQ-i-M20 is an instrument with adequate psychometric properties. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Adaptación de la escala de sentido de capacidad para estudiantes peruanos(Universidad de San Martín de Porres, 2023-12-30)Background: The sense of capability scale, originally validated in French university students (Drouin & Costalat-Founeau, 2020), measures people’s subjective representation of their own capacities and theirperceptions of what others think about them. The aim of this study is to adapt the scale for university students in Lima, Peru and to analyze its psychometric properties. Method: 516 students from a private university completed the questionnaire. Factor analysis and correlations were used to determine evidence of validity. Cronbach’s alpha and McDonald’s omega were used to evaluate reliability. Results: Contrary to the original 2-factor structure, our results suggested a single-factor solution that explained 52% of the variance; the items had high loadings. The model was confirmed by a best fit (χ2 = 362.84; df = 35; p < .001; CFI = .99; TLI = .98; SRMR = .06; RMSEA = .10). A moderate positive correlation was found with positive affect and flourishing, as well as a moderate negative correlation with negative affect. There were no significantdifferences by sex, level, and career type. Conclusion: The new version of the scale shows evidence of adequate validity and reliability (α = .88) in students of a private university in Lima, Peru.
