The effects of survey mode on self-reported psychological functioning: Measurement invariance and latent mean comparison across face-to-face and web modes.

Despite the increasing popularity of mixed-mode approaches to data collection, studies examining measurement equivalence across different survey modes in representative samples of the general population, particularly focusing on measures of socially sensitive psychological constructs, are sparse. In this study, we used data from a large representative sample of the Slovenian population (N = 9,900) collected as part of the third wave of the European Health Interview Survey (EHIS) to examine mode-inherent effects (i.e., measurement effects that cannot be neutralized by clever survey design) of the traditional interviewer-mediated face-to-face mode and the increasingly popular self-administered web mode on three measures of psychological functioning, namely the Patient Health Questionnaire Depression Scale (PHQ-8), the Satisfaction with Life Scale (SWLS), and the Mental Health Continuum - Short Form (MHC-SF). After controlling for self-selection propensities, our results showed strict measurement invariance for all three scales across the two survey modes, but statistically significant and notable differences in latent means, suggesting that individuals who respond face-to-face systematically report better psychological functioning than individuals who respond over the web. These results suggest significant mode inherent effects that cannot be attributed to measurement non-invariance of the scales between face-to-face and web survey modes, but most likely to social desirability bias in responses achieved in the presence of an interviewer. Administration mode effects must be considered when interpreting and comparing results obtained through different survey modes, particularly interviewer-mediated versus self-administered modes, especially when using measures of culturally desirable traits and behaviors, such as mental health and well-being.

Continuous Intravenous versus Subcutaneous Administration of Insulin for Glycemic Variability in Acute Ischemic Stroke.

Background: Continuous intravenous infusion (IV) or subcutaneous injection (SC) of insulin was widely applied to control hyperglycemia after ischemic stroke. However, the impact of different administration modes on glycemic variability was unknown. Methods: Consecutive stroke patients treated with intravenous thrombolysis were screened. Subjects who received insulin treatment were included and entered into the IV or SC group according to the respective administration mode. Blood glucose was closely monitored within the first 72 hours, and the target range of glucose was from 7.7 to 10.0 mmol/L for all patients. The variabilities of glucose, assessed using standard deviation of the mean, variable coefficient and range from the maximum to the minimum value, were compared between the two groups. Results: A total of 130 patients were enrolled with 66 in the IV groups and 64 in the SC group. Compared with the SC group, the IV group had higher glycemic variability evaluated as either standard deviation (2.7 ± 0.7 mmol/L vs 2.2 ± 0.9 mmol/L, p = 0.002), variable coefficient (0.26 ± 0.06 vs 0.23 ± 0.08, p = 0.011) or range (10.0 ± 3.6 mmol/L vs 8.1 ± 3.1 mmol/L, p = 0.001). Multivariate logistic regression analyses found that continuous intravenous infusion was associated with higher level of the standard deviation (adjusted OR 3.01, 95% CI 1.29-7.28, p = 0.011), variable coefficient (adjusted OR 5.97, 95% CI 2.55-13.96, p < 0.001) and range (adjusted OR 6.08, 95% CI 2.63-14.05, p < 0.001). Conclusion: Continuous intravenous infusion of insulin was associated with higher glycemic variability than subcutaneous injection in acute stroke patients receiving thrombolysis.

Computerized testing in reading comprehension skill: investigating score interchangeability, item review, age and gender stereotypes, ICT literacy and computer attitudes.

Score interchangeability of Computerized Fixed-Length Linear Testing (henceforth CFLT) and Paper-and-Pencil-Based Testing (henceforth PPBT) has become a controversial issue over the last decade when technology has meaningfully restructured methods of the educational assessment. Given this controversy, various testing guidelines published on computerized testing may be used to investigate the interchangeability of CFLT and PPBT mean scores to corroborate if test takers' testing performance is influenced by the effects of testing administration mode; specifically, if validity and reliability of two versions of the same test are affected. This research was conducted to probe not only score interchangeability across testing modes but also to explore the role of age and gender stereotypes, item review, ICT literacy and attitudes towards computer use as moderator variables in test takers' reading achievement in CFLT. Fifty-eight EFL learners homogeneous in both general English and reading skills assigned into one testing group participated in this study. Three different versions of TOEFL reading comprehension test, Computer Attitude Scale (CAS), and ICT literacy Scale of TOEFL Examinees were used in this crossover quasi-controlled empirical study with a common-person and pretest-posttest design to collect data. The findings demonstrated that although the reading scores of test takers were interchangeable in both CFLT and PPBT versions regarding testing administration modes, they were different regarding item review. Furthermore, no significant interaction was found between age, gender, and ICT literacy and CFLT performance. However, attitudes towards the use of computer led to a significant change in testing achievement on CFLT.

Equivalence testing of a newly developed interviewer-led telephone script for the EORTC QLQ-C30.

PURPOSE: The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life-Core Questionnaire (QLQ-C30) is a widely used generic self-report measure of health-related quality of life (HRQOL) for cancer patients. However, no validated voice script for interviewer-led telephone administration was previously available. The aim of this study was to develop a voice script for interviewer administration via telephone. METHODS: Following guidelines from the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) PRO Mixed Modes Good Research Practices Task Force, a randomised cross-over equivalence study, including cognitive debriefing, was conducted to assess equivalence between paper and telephone administration modes. Assuming an expected intraclass correlation coefficient (ICC) of 0.70 and a minimally acceptable level of 0.50, a sample size of 63 was required. RESULTS: Cognitive interviews with five cancer patients found the voice script to be clear and understandable. Due to a protocol deviation in the first wave of testing, only 26 patients were available for analyses. A second wave of recruitment was conducted, adding 37 patients (n = 63; mean age 55.48; 65.1% female). Total ICCs for mode comparison ranged from 0.72 (nausea and vomiting, 95% CI 0.48-0.86) to 0.90 (global health status/QoL, 95% CI 0.80-0.95; pain, 95% CI 0.79-0.95; constipation, 95% CI 0.80-0.95). For paper first administration, all ICCs were above 0.70, except nausea and vomiting (ICC 0.55; 95% CI 0.24-0.76) and financial difficulties (ICC 0.60; 95% CI 0.31-0.79). For phone first administration, all ICCs were above 0.70. CONCLUSIONS: The equivalence testing results support the voice script's validity for administration of the QLQ-C30 via telephone.

La Lista de Verificación del Trastorno de Estrés Postraumático (PCL) en víctimas del terrorismo: análisis comparativo de las propiedades psicométricas de su aplicación telefónica frente a presencial / The PTSD Checklist (PCL) in victims of terrorism: Comparative analysis of the psychometric properties of its administration by telephone vs. in person

Introducción y objetivos: En muchas situaciones tales como las de confinamiento provocadas por la pandemia de la COVID-19, es imposible aplicar los instrumentos psicológicos presencialmente, como originalmente se concibieron. Sin embargo, el modo de aplicación puede afectar a las propiedades psicométricas de las medidas de un instrumento. La Lista de Verificación del Trastorno de Estrés Postraumático (del inglés PTSD Checklist; en adelante PCL) es uno de los instrumentos más utilizados para evaluar presencialmente la sintomatología del trastorno de estrés postraumático (TEPT). Este es el primer estudio que analiza y compara la estructura factorial, consistencia interna y validez diagnóstica, nomológica y de grupos contrastados de las medidas de la PCL aplicada presencial y telefónicamente. Material y métodos: Se administró la PCL en ambos formatos a una muestra de 634 personas víctimas del terrorismo junto con una entrevista diagnóstica estructurada y medidas de depresión y ansiedad. Resultados: Las puntuaciones de ambas formas de aplicación de la PCL presentan una misma estructura unifactorial, índices excelentes de consistencia interna (alfa > .90) e índices muy buenos de validez diagnóstica para identificar el TEPT (AUC > .90); ambas discriminan significativamente y con tamaños del efecto grandes (d = 0.88–2.84) entre víctimas con TEPT, con trastornos depresivos o de ansiedad y sin trastornos, y ambas presentan correlaciones significativas y grandes con medidas de otros constructos con los que el TEPT guarda una estrecha relación: depresión y ansiedad. Conclusiones: Los resultados sugieren que la PCL se puede aplicar telefónicamente con las mismas garantías psicométricas que presencialmente.(AU)

Introduction and objectives: In many situations, such as confinement situations caused by the COVID-19 pandemic, it is not possible to administer psychological instruments in person, as originally contemplated in their development. However, the mode of administration can affect the psychometric properties of instrument scores. The PTSD Checklist (PCL) is one of the most widely used instruments for assessing the symptoms of posttraumatic stress disorder (PTSD) in person. This study is the first research that has analyzed and compared the factorial structure, the internal consistency, the validity of contrasted groups, the diagnostic validity, and the nomological validity of scores on the PCL administered in person and by telephone. Material and methods: The PCL was administered in both application modes to a sample of 634 victims of terrorism along with a structured diagnostic interview and measures of depression and anxiety. Results: Scores on both administration modes of the PCL have the same unifactorial structure, excellent indexes of internal consistency (alpha > .90) and very good indexes of diagnostic validity to identify the PTSD (AUC > .90), discriminate significantly and with large effect sizes (d = 0.88–2.84) between victims with PTSD, with depressive or anxiety disorders and without disorders, and present significant and large correlations with measures of other constructs with which PTSD is closely related, namely depression and anxiety. Conclusions: The results suggest that the PCL can be administered over the telephone with the same psychometric guarantees as in person.(AU)

Factors that influence clinical efficacy of live biotherapeutic products.

Traditional probiotics are increasingly being used in a medical context. The use of these products as drugs is considerably different from the traditional use as food or food supplements, as, obviously, the target population is different (diseased versus healthy or at risk population). Besides the target population, also the regulatory context is different, mainly with respect to production, administration regime and type of clinical studies required. In this paper we will, besides the regulatory differences, focus on aspects that may impact the efficacy of a live biotherapeutic product (drug), especially in a clinical setting. The impact of the dosage seems to depend on the strain and the application and may follow some rationale. In contrast, information on the impact of the time of administration or diet, is often still lacking. The matrix and the use of protective measures may clearly have an impact on the survival and efficacy of the strain.

Equivalence of Laptop and Tablet Administrations of the Minnesota Multiphasic Personality Inventory-2 Restructured Form.

The present study investigated the comparability of laptop computer- and tablet-based administration modes for the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). Employing a counterbalanced within-subjects design, the MMPI-2-RF was administered via both modes to a sample of college undergraduates ( N = 133). Administration modes were compared in terms of mean scale scores, internal consistency, test-retest consistency, external validity, and administration time. Mean scores were generally similar, and scores produced via both methods appeared approximately equal in terms of internal consistency and test-retest consistency. Scores from the two modalities also evidenced highly similar patterns of associations with external criteria. Notably, tablet administration of the MMPI-2-RF was substantially longer than laptop administration in the present study (mean difference 7.2 minutes, Cohen's d = .95). Overall, results suggest that varying administration mode between laptop and tablet has a negligible influence on MMPI-2-RF scores, providing evidence that these modes of administration can be considered psychometrically equivalent.

Impact of administration mode on Oro-facial Appearance assessment using the Oro-facial Esthetic Scale.

BACKGROUND: Oro-facial Appearance is increasingly recognised as an important component of patient-reported outcomes in dentistry. While the Oro-facial Esthetic Scale (OES) has sufficient psychometric properties to characterise dental patient's global assessment of Oro-facial Appearance, the equivalence of alternative methods of administration has not been demonstrated so far. OBJECTIVE: Aim of this study was to investigate whether and to what extent method of administration affects OES scores. METHODS: Participants were recruited as convenience sample of 42 adult dental patients registered for a regular recall visit and with no actual need of dental interventions. Oro-facial Appearance was assessed using the German version of the OES applying three methods of administration: (a) face-to-face interview, (b) self-administered questionnaire and (c) telephone interview, in a randomised order with a period of about one week between assessments. RESULTS: Oro-facial Esthetic Scale summary scores did not differ substantially or statistically significantly between the different methods of administration (two-way ANOVA; P = 0.209). Intraclass correlation coefficients (ICC) for pairwise comparisons of administration modes ranged from 0.67 to 0.84 indicating fair to excellent test-retest reliability. Internal consistency was satisfactory with lower limits of the 95% confidence interval (CI) of Cronbach's alpha ranging from 0.82 to 0.88 for the administration modes. Correlations of the OES summary score with a single item assessing global Oro-facial Appearance supported convergent validity with lower limits of the CI of the correlation coefficients ranging between 0.58 and 0.75. CONCLUSION: The administration mode has no significant impact on Oro-facial Appearance assessment when using the OES.

Prevalence and factors associated with use of hookah tobacco among young adults in the U.S.

INTRODUCTION: Among young adults, use of hookah tobacco (HT) is an emerging health-risk behavior. The goals were to demonstrate that (1) the prevalence of ever-use and current use of HT increased among U.S. young adults (18-30 years old) in the period from 2010 to 2015 and (2) the patterns of HT use differed across diverse demographic subpopulations of young adults. METHODS: We merged and analyzed data from the 2010-2011 and 2014-2015 Tobacco Use Supplement to the Current Population Survey. The sample (n = 55,352) was representative of the young adult population in the U.S. Two binary measures were the ever and current use of HT. The significance level was 5%. RESULTS: The rate of current use of HT increased from 1% in 2010-11 to 2% in 2014-15 (CI = 0.6%:1.1%). The rate of ever-use increased from 7% to 12% (CI = 4.2%:5.6%). The over-time increase was not uniform: the increase was most rapid among 26-30 year-old adults, non-Hispanic Black and African American adults, and in Northeastern and Midwestern U.S. regions. HT ever-use, overall, was associated (all p's < 0.001) with many sociodemographic factors and current tobacco-use behaviors. The rate of HT ever-use was 16% for daily and 23% for occasional cigarette smokers, 23% for users of smokeless tobacco products, 37% for cigar smokers, and 55% for smokers of regular pipe (filled with tobacco). DISCUSSION/CONCLUSION: HT use is becoming increasingly more popular among young adults in the U.S. Methods should target not only cessation of cigarette smoking but use of all tobacco products.

Are differences in population prevalence of alcohol's harm to others related to survey administration mode?

INTRODUCTION AND AIMS: This study assessed the comparability of estimates of alcohol's harm to others across different administration modes in Swedish general population surveys. Harm was categorised as harm from strangers' drinking and harm from heavy drinkers known to the respondent. DESIGN AND METHODS: Three surveys were conducted in 2011/2012 (n = 6841), including identical questions. One was based on self-administered postal or Web questionnaires, and two were based on computer-assisted telephone interviews of which one included a more ambitious procedure in terms of for example monetary incentives to the respondents. Pearson χ2 -tests were used to compare differences in the prevalence of harm. To estimate potential effects of survey mode, the samples were pooled, and multivariate Poisson regression models with mode as explanatory variable were used, adjusting for socio-demographic and behavioural factors. RESULTS: Respondents in the two computer-assisted telephone interviews were more likely to report harm from strangers' drinking compared with respondents in the self-administered postal or Web questionnaires. However, no significant differences were found between survey modes concerning reports of harm from known people's drinking. DISCUSSION AND CONCLUSIONS: A survey mode based on interviews seems to facilitate reports of harm from strangers' drinking. This does not apply to reports of harm from known people's drinking. Therefore, the comparability of estimates of alcohol's harm to others between survey modes depends on the type of harm being studied. [Sundin E, Landberg J, Galanti MR, Room R, Ramstedt M. Are differences in population prevalence of alcohol's harmto others related to survey administration mode?

Impact of Survey Administration Mode on the Results of a Health-Related Discrete Choice Experiment: Online and Paper Comparison.

BACKGROUND: Electronic data collection is increasingly being used for discrete choice experiments (DCEs). OBJECTIVES: To study whether paper or electronic administration results in measurement effects. METHODS: Respondents were drawn from the same sample frame (an Internet panel) and completed a nearly identical DCE survey either online or on paper during the same period. A DCE on preferences for basic health insurance served as a case study. We used panel mixed logit models for the analysis. RESULTS: In total, 898 respondents completed the survey: 533 respondents completed the survey online, whereas 365 respondents returned the paper survey. There were no significant differences with respect to sociodemographic characteristics between the respondents in both samples. The median response time was shorter for the online sample than for the paper sample, and a smaller proportion of respondents from the online sample were satisfied with the number of choice sets. Although some willingness- to-pay estimates were higher for the online sample, the elicited preferences for basic health insurance characteristics were similar between both modes of administration. CONCLUSIONS: We find no indication that online surveys yield inferior results compared with paper-based surveys, whereas the price per respondent is lower for online surveys. Researchers might want to include fewer choice sets per respondent when collecting DCE data online. Because our findings are based on a nonrandomized DCE that covers one health domain only, research in other domains is needed to support our findings.

Research on value of different administration models of tiotropium bromide applied to treat asthma combined with COPD / 中国生化药物杂志

Objective To explore clinical value of different administration modes applied to treat the asthma combined with chronic obstructive pulmonary disease ( COPD ) .Methods Clinical data of 180 patients with bronchial asthma combined with COPD admitted by the department of respiratory medicine of the Hospital from June 2013 to June 2015 were retrospectively analyzed, and such patients were divided into three groups including 58 patients in the control group, 60 patients in the observation group A and 62 patients in observation group B ( n =62 ) in random cross double-blind method.The patients in the control group were administered and treated with placebo ( once in the morning and at night daily respectively) , the patients in the observation group A were administered and treated with 2.5 μg of tiotropium bromide ( once in the morning and at night daily respectively), and the patients in the observation group B were treated with 2.5 μg of tiotropium bromide (once at night daily respectively), and the treatment efficacy on three groups of patients were observed.Results Average questionnaire scores of FEV1, AUC0 ~24 h , FEV1(0 ~24 h) peak valley value, PEFam , PEFpm , FEV1 and ACQ -7 in 24 hours of patients in the observation group A and observation group B, there were no statistically significant differences between two groups;Questionnaire scores of FEV1, AUC0 ~24 h , FEV1(0 ~24 h) peak valley value, PEFam , PEFpm , FEV1 and ACQ-7 in 24 hours of patients in the observation group A and observation group B were significantly higher than such indexes of patients in the control group, and the differences were statistically significant ( P <0.05 ) .Conclusion Two different dosage regimens of tiotropium bromide with daily dose of 5 μg can significantly keep the bronchus expanding for 24 h, and delivers significant efficacy on the asthma combined with COPD treatment.
