Willingness To Forgive

PurposeThough brand love is recognized as being an important marketing topic both for theory and practice, a gap still exists with regard to its operationalization. To bridge this gap, this paper proposes a single-item measure (SIM) that uses a visual rating scale (i.e., a rating scale combining verbal with nonverbal contents).Design/methodology/approachThree studies covering over 700 respondents and examining three international brands over three product categories were conducted to test the new measure.FindingsFindings provide consistent evidence for the reliability and validity of the proposed measure. They also demonstrate that brand love, as gauged by the new SIM, is good in predicting positive word of mouth, willingness to pay a higher price, and willingness to forgive brand mishaps.Research limitations/implicationsThe paper focuses on brand love mainly from a measurement perspective.Practical implicationsThis paper provides a practical and parsimonious tool to measure brand love.Originality/valueExtant SIMs of brand love are less than ordinal, content invalid, of unknown reliability, and of untested concurrent validity. This paper provides academics and practitioners alike with a SIM of brand love that is ordinal, content valid, and tested in terms of reliability and concurrent validity.

Item Scale

BackgroundRegular assessment of mood is often important for treatment but traditional measures can be time-consuming. A quick ‘litmus test’ is needed.AimsTo test the reliability and validity of a single-item scale for mood.MethodMood was measured repeatedly in 812 patients (258 in-patients, 554 out-patients) being treated in an anxiety disorders unit. Patients had self- and clinician ratings of a single-item depression scale and also rated the 21-item Beck Depression Inventory (BDI–21). Their single-item scores were compared with BDI–21 scores and with outcome measures.ResultsThe single-item depression scores correlated 0.71 to 0.78 with the BDI–21 scores. Clinically useful cut-off points were identified. Depression scores at discharge, but not pre-treatment, correlated significantly with improvement in the main problem.ConclusionsThe quick single-item depression scale, whether rated by patient or by clinician, is a reasonable rough guide to mood in anxiety disorders and saves time for the patient and the clinician compared to longer measures.

Purpose Loudness is a major auditory dimension of tinnitus and is used to diagnose severity, counsel patients, or as a measure of clinical efficacy in audiological research. There is no standard test for tinnitus loudness, but matching and rating methods are popular. This article provides important new knowledge about the reliability and validity of an audiologist-administered tinnitus loudness matching test and a patient-reported tinnitus loudness rating. Method Retrospective analysis of loudness data for 91 participants with stable subjective tinnitus enrolled in a randomized controlled trial of a novel drug for tinnitus. There were two baseline assessments (screening, Day 1) and a posttreatment assessment (Day 28). Results About 66%–70% of the variability from screening to Day 1 was attributable to the true score. But measurement error, indicated by the smallest detectable change, was high for both tinnitus loudness matching (20 dB) and tinnitus loudness rating (3.5 units). Only loudness rating captured a sensation that was meaningful to people who lived with the experience of tinnitus. Conclusions The tinnitus loudness rating performed better against acceptability criteria for reliability and validity than did the tinnitus loudness matching test administered by an audiologist. But the rating question is still limited because it is a single-item instrument and is probably able to detect only large changes (at least 3.5 points).

PurposePrevious studies have proposed that correctly managing stakeholders with certain attributes can benefit project management; however, robust theoretical elaborations and empirical investigations of this topic have been lacking. The purpose of this study is to empirically test the effects of two stakeholder attributes – contractor-perceived contractor salience and contractor project position – on the criticality of five typical contractor-related risks: risk of (1) injuries and accidents, (2) quality defects, (3) work delays, (4) cost overruns and (5) breaches of contract.Design/methodology/approachQuestionnaire data were collected from 118 Chinese contractor managers. Regression models were run in Mplus 7.11 to test the hypotheses.FindingsThe data show that higher contractor-perceived contractor salience and a more supportive contractor project position were both related to lower criticality of contractor-related risks, including risk of (1) injuries and accidents, (2) quality defects, (3) work delays, (4) cost overruns and (5) breaches of contract. Contractor salience also mediated the negative relationship between a supportive contractor project position and the criticality of contractor-related risks.Research limitations/implicationsThe authors’ research design is cross-sectional and thus cannot establish causation in the relationships among the studied variables. The single item measure of contractor project position was used for the first time in the present study; thus, its reliability and validity still await more empirical examinations.Originality/valueThe findings advance the understanding of the value of stakeholder management in projects by specifying that prioritizing stakeholders' claims and securing their support for the project reduce the criticality of stakeholder-related risks. By providing empirical evidence from the construction context, the findings also add to knowledge on the instrumental power of stakeholder management in enhancing project risk management performance.

AbstractThe Physical and Emotional Tormenting Against Animals Scale (P.E.T.) is a new self-administered scale to measure physical and emotional abuse against animals among adolescents. This study is a first attempt to establish the reliability and validity of this newly developed scale with a non-clinical sample of 1396 Italian adolescents, aged 11-17 years.The scale measures different dimensions of animal abuse, ranging from mild to more severe: bothering, tormenting, hitting, harming, and being cruel to an animal. The scale measures the prevalence and frequency of directed and witnessed abuse against animals. Principal components analysis suggested a two factor solution, with factors labeled "direct" and "indirect" animal abuse; internal consistency was good for each factor.The direct animal abuse factor was significantly correlated with the Child Behavior Checklist's single item assessing engagement in cruelty against animals. These findings suggest that the PET scale has potential as an instrument for the measurement of animal abuse. Future studies of the PET scale's psychometric properties, and cross-validation on new populations, are needed.

Care Satisfaction

We decided to develop a short-form of the CHC-SUN/YHC-SUN, a questionnaire aiming at assessing health care satisfaction of children and adolescents with chronic health conditions. Data analysis was based on samples from three different studies. Item selection involved statistical analysis and expert consensus. For independent validation purposes, we calculated descriptive statistics on single-item and composite-scale levels and applied classic test theory, confirmatory factor analyses, and correlation analysis to investigate the psychometric properties of the final short-form by different types of reliability and validity. Internal consistency (Cronbach’s Alpha) reached values of a = 0.89 (self-report) and a = 0.92 (parents report), split-half reliability values reached 0.85 (self-report) and 0.91 (parents report). Confirmatory factor analysis indicated no sufficient fit for the single factor solution, whereas the solution with three factors and one higher order factor indicated the best overall fit amongst three competing models. Validity of the short-form measure can be assumed, e.g., as indicated by its association with a single-item measure on general health care satisfaction. The short-form measures of the CHC-SUN for parents (CHC-SUN-SF) and the YHC-SUN self-report version for adolescents (YHC-SUN-SF) feature excellent psychometric performances, provide economical assessments, and are easy-to-administer questionnaires. They should be used whenever brief measures are needed for economic reasons.

ABSTRACTBackground:A single-item depression measure may not be adequate in capturing the complex entity of mental health, despite wide use of this indicator in community studies. This study evaluated the accuracy of a single-question depression measure in comparison to two composite indices–the Center for Epidemiologic Studies Depression Scale (CESD) and the Geriatric Depression Scale (GDS).Materials and methods:A total of 800 elderly participants ranging from 60 to 89 years of age and residing in Seoul were recruited using a multistage sampling scheme in 2015. The survey was conducted by trained interviewers with a constructed questionnaire. Reliability and validity measures such as the Kappa index, sensitivity, specificity, PPV, NPV, and AUC were used to evaluate the accuracy of the single question measure. Socio-demographic group differences in accuracy were compared by age, sex, marital status, education, employment, and financial status.Results:The prevalence of depression by a single-question measure was much lower than those of CESD and GDS (5.5%, 12.3%, and 12.1%, respectively). The sensitivity of the single-item measure, based on CESD and GDS, was extremely low at 30.6% and 36.1%. In the subgroup analysis, however, there was a marked educational discrepancy in all accuracy measures; in sensitivity, people with a university degree or higher showed about 2.4 times higher sensitivity than those having only a primary school education.Conclusions:The results show that a single-question depression measure should be used with caution. In addition, the single-question measure could substantially underestimate depression among the risk group of older adults.
