To B or not to B: Arsenophonus as a source of B-vitamins in whiteflies
2018
1AbstractInsect lineages feeding on nutritionally restricted diets such as phloem, xylem, or blood, were able to diversify by acquiring bacterial species that complemented the missing nutrients. These bacteria, considered obligate/primary endosymbionts, share a long evolutionary history with their hosts. In some cases, however, these endosymbionts are not able to fulfill all the nutritional requirements of their host, driving the acquisition of additional symbiotic species. Whiteflies, which feed on phloem, established an obligate relationship with Candidatus Portiera aleyrodidarum, who provides essential amino acids and carotenoids to the host. As many Whiteflies species harbor additional …

Comparative validity of the OIDP and OHIP-14 in describing the impact of oral health on quality of life in a cross-sectional study performed in Spani…
2010
Objectives: We aimed to compare the utility and validity of two popular socio-dental indicators (OIDP and OHIP- 14) for describing the impact of oral conditions on quality of life applied simultaneously. Study design: We recruited a consecutive sample of 270 healthy Spanish workers visiting the Employment Risk Prevention Centre for a routine medical check-up. OHIP-14 was self-completed before the oral examination and the face to face interview of the OIDP was performed. Both instruments were compared by evaluating its reliability and its validity. Results and Conclusions: The standardised Cronbach alphas for OHIP-14 and OIDP were 0.89 and 0.74 respectively. OIDP showed lower face validity b…
Reliability and Validity of Family Affluence Scale (FAS II) among Adolescents in Beijing, China
2011
This study comprises two sub-studies. Study I assessed the test-retest reliability of Family Affluence Scale (FAS II) items among 95 students aged 11 and 15 years old in Beijing. Study II investigated the completion rate of traditional indicators (parents’ educational level, perceived family wealth, resident area, and school location) measuring socioeconomic status (SES) compared with FAS II, and examined the internal reliability, external and construct validity of the FAS II items in a population of 5876 schoolchildren aged 11, 13 and 15 years old in Beijing. Our study found that the FAS II items have high completion rates (> 99%) which are better than other SES indicators. Analyses of rel…
Measurement of the will to live in older adults: Transcultural adaptation, validity and reliability of the Will-to-Live Scale
2019
Abstract Objective The Will-to-Live Scale (WTLS) is used to measure the will to live in older adults; however, there is no Spanish version. The objective of the study was to translate the WTLS into Spanish, assess its internal structure, reliability, and the correlates between WTLS and life satisfaction, resilience, and depression in older Peruvian adults. Method The participants were 235 Peruvian older adults (M = 72.69, SD = 6.68), evaluated between March to May 2019, selected through non-probability sampling. The WTLS, the Satisfaction with Life Scale (SWLS), the Brief Resilient Coping Scale (BRCS) and the Patient Health Questionnaire-2 (PHQ-2) were administered. Data analysis included r…

Testing and comparing two self-care-related instruments among older Chinese adults
2017
Objectives The study aimed to test and compare the reliability and validity, including sensitivity and specificity of the two self-care-related instruments, the Self-care Ability Scale for the Elderly (SASE), and the Appraisal of Self-care Agency Scale-Revised (ASAS-R), among older adults in the Chinese context. Methods A cross-sectional design was used to conduct this study. The sample consisted of 1152 older adults. Data were collected by a questionnaire including the Chinese version of SASE (SASE-CHI), the Chinese version of ASAS-R (ASAS-R-CHI) and the Exercise of Self-Care Agency scale (ESCA). Homogeneity and stability, content, construct and concurrent validity, and sensitivity and spe…
Validation of Doloplus-2 among nonverbal nursing home patients : an evaluation of Doloplus-2 in a clinical setting
2010
Published version of an article from the journal: BMC Geriatrics. Also available from the publisher: http://dx.doi.org/10.1186/1471-2318-10-9 BACKGROUND:Pain measurement in nonverbal older adults is best based on behavioural observation, e.g. using an observational measurement tool such as Doloplus-2. The purposes of this study were to examine the use of Doloplus-2 in a nonverbal nursing home population, and to evaluate its reliability and validity by comparing registered nurses' estimation of pain with Doloplus-2 scores.METHOD:In this cross-sectional study, Doloplus-2 was used to observe the pain behaviour of patients aged above 65 years who were unable to self-report their pain. Nurses al…
