Abstract Online self-reported 24-h dietary recall systems promise increased feasibility of dietary assessment. Comparison against interviewer-led recalls established their convergent validity; however, reliability and criterion-validity information is lacking. The validity of energy intakes (EI) reported using Intake24, an online 24-h recall system, was assessed against concurrent measurement of total energy expenditure (TEE) using doubly labelled water in ninety-eight UK adults (40–65 years). Accuracy and precision of EI were assessed using correlation and Bland–Altman analysis. Test–retest reliability of energy and nutrient intakes was assessed using data from three further UK studies where participants (11–88 years) completed Intake24 at least four times; reliability was assessed using intra-class correlations (ICC). Compared with TEE, participants under-reported EI by 25 % (95 % limits of agreement −73 % to +68 %) in the first recall, 22 % (−61 % to +41 %) for average of first two, and 25 % (−60 % to +28 %) for first three recalls. Correlations between EI and TEE were 0·31 (first), 0·47 (first two) and 0·39 (first three recalls), respectively. ICC for a single recall was 0·35 for EI and ranged from 0·31 for Fe to 0·43 for non-milk extrinsic sugars (NMES). Considering pairs of recalls (first two v. third and fourth recalls), ICC was 0·52 for EI and ranged from 0·37 for fat to 0·63 for NMES. EI reported with Intake24 was moderately correlated with objectively measured TEE and underestimated on average to the same extent as seen with interviewer-led 24-h recalls and estimated weight food diaries. Online 24-h recall systems may offer low-cost, low-burden alternatives for collecting dietary information.

Preliminary research has suggested that wearable cameras may reduce under-reporting of energy intake (EI) in self-reported dietary assessment. The aim of the present study was to test the validity of a wearable camera-assisted 24 h dietary recall against the doubly labelled water (DLW) technique. Total energy expenditure (TEE) was assessed over 15 d using the DLW protocol among forty adults (n 20 males, age 35 (sd 17) years, BMI 27 (sd 4) kg/m2 and n 20 females, age 28 (sd 7) years, BMI 22 (sd 2) kg/m2). EI was assessed using three multiple-pass 24 h dietary recalls (MP24) on days 2–4, 8–10 and 13–15. On the days before each nutrition assessment, participants wore an automated wearable camera (SenseCam (SC)) in free-living conditions. The wearable camera images were viewed by the participants following the completion of the dietary recall, and their changes in self-reported intakes were recorded (MP24+SC). TEE and EI assessed by the MP24 and MP24+SC methods were compared. Among men, the MP24 and MP24+SC measures underestimated TEE by 17 and 9 %, respectively (P< 0·001 and P= 0·02). Among women, these measures underestimated TEE by 13 and 7 %, respectively (P< 0·001 and P= 0·004). The assistance of the wearable camera (MP24+SC) reduced the magnitude of under-reporting by 8 % for men and 6 % for women compared with the MP24 alone (P< 0·001 and P< 0·001). The increase in EI was predominantly from the addition of 265 unreported foods (often snacks) as revealed by the participants during the image review. Wearable cameras enhance the accuracy of self-report by providing passive and objective information regarding dietary intake. High-definition image sensors and increased imaging frequency may improve the accuracy further.

Background: A large-scale online study completed by this research team found that brief psychological interventions were associated with high-intensity pleasant emotions and predicted performance. The present study extends this work using data from participants (n = 3376) who completed all self-report data and engaged in a performance task but who did not engage with an intervention or control condition and therefore present as an opportunistic no-treatment group. Methods: 41,720 participants were selected from the process and outcome focus goals intervention groups, which were the successful interventions (n = 30,096), active-control (n = 3039), and no-treatment (n = 8585). Participants completed a competitive task four times: first as practice, second to establish a baseline, third following an opportunity to complete a brief psychological skills intervention, and lastly following an opportunity to repeat the intervention. Repeated measures MANOVA indicated that over four performance rounds, the intensity of positive emotions increased, performance improved, and the amount of effort participants exerted increased; however, these increases were significantly smaller in the no-treatment group. Conclusions: Findings suggest that not engaging in active training conditions had negative effects. We suggest that these findings have implications for the development and deployment of online interventions.

AbstractObjectiveAs misreporting, mostly under-reporting, of dietary intake is a generally known problem in nutritional research, we aimed to analyse the association between selected determinants and the extent of misreporting by the duplicate portion method (DP), 24 h recall (24hR) and FFQ by linear regression analysis using the biomarker values as unbiased estimates.DesignFor each individual, two DP, two 24hR, two FFQ and two 24 h urinary biomarkers were collected within 1·5 years. Also, for sixty-nine individuals one or two doubly labelled water measurements were obtained. The associations of basic determinants (BMI, gender, age and level of education) with misreporting of energy, protein and K intake of the DP, 24hR and FFQ were evaluated using linear regression analysis. Additionally, associations between other determinants, such as physical activity and smoking habits, and misreporting were investigated.SettingThe Netherlands.SubjectsOne hundred and ninety-seven individuals aged 20–70 years.ResultsHigher BMI was associated with under-reporting of dietary intake assessed by the different dietary assessment methods for energy, protein and K, except for K by DP. Men tended to under-report protein by the DP, FFQ and 24hR, and persons of older age under-reported K but only by the 24hR and FFQ. When adjusted for the basic determinants, the other determinants did not show a consistent association with misreporting of energy or nutrients and by the different dietary assessment methods.ConclusionsAs BMI was the only consistent determinant of misreporting, we conclude that BMI should always be taken into account when assessing and correcting dietary intake.

Using Data

The main purpose of this study is to identify the underlying dimensions of consumer complaining and recovery effort and to develop a multidimensional scale to measure this construct. Literature suggests that the consumer complaining and recovery effort is a four-dimensional construct consisting of procedural, cognitive, time-related, and affective components. Using data collected from hotel guests, a measurement scale is developed to assess this four-dimensional construct. First, a factor analysis is conducted on one set of data. Afterward, the underlying dimensions identified by the exploratory factor analysis are confirmed by conducting a confirmatory factor analysis on a separate set of data. Findings suggest that the scale developed in this study presents substantial convergent validity, discriminant validity, predictive validity, and reliability.

Abstract. The present research presents evidence of the validity and reliability of an abbreviated version of the Perceived Affect Utility Scale (PAUSe). In Study 1, findings using item response theory (IRT) led to the deletion of one-third of the number of items in the PAUSe. Results from confirmatory factor analysis (CFA) supported the structure of the abbreviated version of the PAUSe, the PAUSe-r. Examining effect sizes between the PAUSe-r and instruments measuring personality, emotion, and depression also supported the convergent validity, discriminant validity, and incremental validity of this measure, even after taking into account ideal affect and the actual experience of emotion. In Study 2, test-retest reliability of the PAUSe-r in a sample of college students is presented. In Study 3, using data from a large, nonstudent sample, we replicated the structure of the PAUSe-r, as well as relations between the PAUSe-r and personality variables, that were found in Study 1.

Validity And Reliability

The objective of this study was to assess the psychometric properties of the Latvian version of the Flourishing Scale (FS), created by Diener et al. (2010). FS is a brief self-report measure of the respondent’s well-being and success in areas of relationships, self-esteem, purpose, and optimism. The scale provides a single score across 8 items. The original FS was translated to Latvian and then back to English. The Satisfaction with Life Scale and Meaning in Life Questionnaire was applied for testing the convergent validity of the FS. Participants of the study were 191 people, ranged in age from 19 to 68 (159 women, mean age M = 30.62, SD = 9.50). Reliability analysis, exploratory and confirmatory factor analysis (EFA and CFA) of the scale were performed. EFA indicated a one-factor structure. Results showed that the Latvian version of FS has good psychometric properties and demonstrated convergent validity. Testing of the original model by CFA resulted in acceptable fit indices.

Skipping meals is a poor eating behaviour known to result in poor diet quality and health outcomes. Nevertheless, it has become increasingly common over the past few decades in many countries. This study aimed to examine the potential association between the use of workplace foodservices and skipping meals among Korean adult workers using data from the Korea National Health and Nutrition Examination Survey 2016–2018, a nationwide cross-sectional survey of a representative Korean population. A total of 5,137 workers aged 20–64 years were included. Dietary assessment was conducted using a 24-hour dietary recall. In total, 41.2% participants skipped one meal or more per day. The percentage of workers who skipped meals was 43.1±1.0% among participants who did not use workplace foodservices compared to 31.8±1.9% among those who did (P<0.01). Skipping meals was significantly associated with not using workplace foodservices, after adjusting for other confounders including sociodemographic variables, health-related variables, and meal procurement source (odds ratio = 3.4; 95% confidence interval = 2.6–4.4; P<0.01). We found a significant association between using workplace foodservices and reduced skipping meals in Korean adult workers. This study suggests the importance of the provision of workplace foodservices for workers to potentially reduce poor eating behaviours such as skipping meals.

Across many scientific disciplines, methods for recording, storing, and analyzing data are rapidly increasing in complexity. Skillfully using data science tools that manage this complexity requires training in new programming languages and frameworks as well as immersion in new modes of interaction that foster data sharing, collaborative software development, and exchange across disciplines. Learning these skills from traditional university curricula can be challenging because most courses are not designed to evolve on time scales that can keep pace with rapidly shifting data science methods. Here, we present the concept of a hack week as an effective model offering opportunities for networking and community building, education in state-of-the-art data science methods, and immersion in collaborative project work. We find that hack weeks are successful at cultivating collaboration and facilitating the exchange of knowledge. Participants self-report that these events help them in both their day-to-day research as well as their careers. Based on our results, we conclude that hack weeks present an effective, easy-to-implement, fairly low-cost tool to positively impact data analysis literacy in academic disciplines, foster collaboration, and cultivate best practices.

Self-report delinquency scales have contributed greatly to the contemporary basis of our understanding of juvenile delinquency. Nevertheless, they have not been immune to criticism and further improvement and extensive measurement research is still necessary. The present study examined the psychometric properties of one such measure of self-reported delinquency, the Adapted Self-Report Delinquency Scale (ASRDS). The ASRDS was administered to a Portuguese sample of male youths ( N = 470, 12-20 years of age), subdivided into a forensic sample ( n = 217) and a school sample ( n = 253). The Portuguese version of the ASRDS demonstrated satisfactory psychometric properties, in terms of its factor structure, internal consistency, convergent validity, discriminant validity, criterion-related validity, and known-groups validity, thereby justifying its use among this population.
