Integrating Models and Data to Estimate the Structural Reliability of Utility Poles During Hurricanes

Utility systems such as power and communication systems regularly experience significant damage and loss of service during hurricanes. A primary damage mode for these systems is failure of wooden utility poles that support conductors and communication lines. In this article, we present an approach for combining structural reliability models for utility poles with observed data on pole performance during past hurricanes. This approach, based on Bayesian updating, starts from an imperfect but informative prior and updates this prior with observed performance data. We consider flexural and foundation failure mechanisms in the prior, acknowledging that these are an incomplete, but still informative, subset of the possible failure mechanisms for utility poles during hurricanes. We show how a model‐based prior can be updated with observed failure data, using pole failure data from Hurricane Katrina as a case study. The results of this integration of model‐based estimates and observed performance data then offer a more informative starting point for power system performance estimation for hurricane conditions.     

Statistical inference of agreement coefficient between two raters with binary outcomes

Abstract

Scott’s pi and Cohen’s kappa are widely used for assessing the degree of agreement between two raters with binary outcomes. However, many authors have pointed out its paradoxical behavior, that comes from the dependence on the prevalence of a trait under study. To overcome the limitation, Gwet [Computing inter-rater reliability and its variance in the presence of high agreement. British Journal of Mathematical and Statistical Psychology 61(1):29–48] proposed an alternative and more stable agreement coefficient referred to as the AC₁. In this article, we discuss a likelihood-based inference of the AC₁ in the case of two raters with binary outcomes. Construction of confidence intervals is mainly discussed. In addition, hypothesis testing, and sample size estimation are also presented.     

LoTTS parent-infant interaction coding scale: Ease of use and reliability in a sample of high-risk mothers and their infants

Reliable and valid measurement of parent-infant interactions is necessary to demonstrate parental skill acquisition, but existing observational coding schemes are too complex for practical use in most human service settings. The LoTTS Parent-Infant Interaction Coding System (LPICS) was developed specifically to require minimal training and to be maximally useful for human service (rather than research) settings. The LPICS consists of three global scales and four behavioral counts. Undergraduate students participated in approximately 9 h of training and coding using the LPICS. Low inter-rater reliability scores initially necessitated modifications to the LPICS in order to enhance reliability. The revised scoring procedure showed more promise, particularly for three behavior counts: talking to the infant (ICC = .86, excellent), touching the infant (ICC = .90, excellent), and smiling at the infant (ICC = .66, good), and one global scale: parental warmth (ICC = .58, fair). The revised LPICS may have utility as a brief, simple, and easy-to-teach observational measure of parent-infant interactions.     

Development of a Measure of College Students' Adherence to Religious Doctrine Concerning Sexual Behavior

Abstract

Objective: The authors developed a 14-item measure of adherence to religious doctrine concerning sexual behavior (ARDSB). The ARDSB psychometric properties were investigated to better understand religious motivations associated with changes in sexual behavior that may provide support for sexual health promotion and prevention programs. Participants: Four hundred eighty-three undergraduates aged 18 to 26. Methods: Data were collected from an online survey during the 2012–2013 academic school year. Results: Principle components factor analysis identified 2 factors: reasons to break religious doctrine and reasons to adhere to religious doctrine concerning sexual behavior. The subscales had good internal consistency. Correlations, t tests, and analyses of variance of the subscales with measures of intrinsic and extrinsic religiosity and self-reported sexual behavior and risk provide support for concurrent validity. Conclusions: The ARDSB could be employed as a measure to better understand sexual behavior; it is inexpensive and relatively easy to employ in both research and campus ministry settings.     

A Preliminary Assessment of the Validity and Reliability of the Performance Diagnostic Checklist-Human Services

ABSTRACT

The Performance Diagnostic Checklist-Human Services (PDC-HS) is an informant-based tool used to identify the environmental variables contributing to employee performance problems in human service settings. Although previous research has suggested that the tool is useful to identify an intervention which can be used to improve performance, no studies have formally examined the validity and reliability of the tool. In this study, we used video vignettes to assess the validity and reliability of the PDC-HS. We created three videos; each described a performance problem in one or more of the four PDC-HS domains. Twenty-one participants then watched the videos and evaluated the performance problem depicted using the PDC-HS. We measured the validity of the tool by calculating the percentage of participants who correctly identified the PDC-HS domain responsible for the performance problem. Two to four weeks later, we had participants re-watch the videos and complete the PDC-HS to obtain a measure of test re-test reliability. We also compared PDC-HS item responses across participants to evaluate inter-rater reliability. Results show that all participants correctly identified the problematic PDC-HS domain(s) in each video. PDC-HS validity values were above 93% across all three videos and domains; mean test re-test and interrater reliability values were above 95%. The results are discussed in terms of the preliminary nature of this analysis; although these data are limited by the amount and clarity of the information provided in the videos, this study represents a necessary first step in the assessment of the reliability and validity of the PDC-HS tool.     

Limited Nomination Reliability Using Single‐ and Multiple‐item Measures

This article examines a variety of reliability issues as related to limited nomination sociometric measures. Peer nomination data were collected from 77 sixth grade classrooms. Results showed that, although some single‐item peer nomination measures were relatively reliable, many single‐item peer nomination measures using limited nominations were quite unreliable. Overt aggression nomination items were the only set of single‐item measures where mean classroom reliability estimates were .75 or greater. Combining multiple items led to substantially better reliability, as combining the two least reliable items for a category into a single measure made the composite more reliable than the most reliable single measure. Having more nominators in the sample also increased reliability. The limited nomination items overall tended to be less reliable than similar unlimited nomination items from other studies. The authors end with recommendations for obtaining the most reliable peer nomination data possible from a study.     

Court Ordered Multiple Offender Drunk Drivers: Validity and Reliability of Rapid Assessment

ABSTRACT

The Alcohol Use Disorders and Associated Disabilities Interview Schedules' (AUDADIS) DSM-IV related items are used to evaluate the convergent validity of the Severity of Alcohol Dependence Questionnaire (SAD-Q), the Michigan Alcoholism Screening Test (MAST), and the Alcohol Use Disorders Identification Test (AUDIT) with persons convicted for multiple offences of driving under the influence. A total of 187 participants underwent semi-structured interviewing; of these 84% were alcohol dependent. The instruments exhibit acceptable internal consistency (all alphas > .85) as well as test/re-test reliability (all r = s ≥ .85). The MAST converged most closely with a DSM-IV diagnosis. Implications for rapid assessment instrument research as well as practice in public agencies are discussed.
