A Generalized Strategy for Measuring Performance in the Velocity-Position Phase Plane

Subjects pressed a key down as fast as possible but controlled the response duration of the keypress. The task required long (300 ±100 msec) and short (150±50 msec) durations in both simple (long only or short only) and choice (mixed long and short) conditions. Choice reaction time was slower than simple reaction time, but reaction time for long and short durations did not differ significantly for either simple or choice conditions. This finding fails to support a study by Klapp, Wyatt, and Lingo (1974) which found reaction time differences between long and short durations for choice but not simple conditions.     

Reliability and Validity of Single-Item Self-Reports: With Special Relevance to College Students' Alcohol Use,Religiosity, Study,and Social Life

The authors tested the assumption that single-item measures have unacceptably low reliability and validity. On 2 occasions 11 weeks apart, college students reported on the frequency and quantity of alcohol consumption, 2 religious behaviors, time of study and of socializing (focal items), and other qualities and characteristics. Most test-retest reliabilities were good to excellent; objective facts were more reliable than subjective evaluations; and target items had good validity when correlated with 2-week nightly log records of corresponding behaviors in a multimethod multitrait matrix. The exception was self-reported study, with relatively low reliability and validity, suggesting the non-trait-like quality of this behavior. Single-item measures may be better than commonly thought.     

Measurement Equivalence/Invariance of the Abusive Supervision Measure Across Workers From Taiwan and the United States

Growing international research interest in negative-leadership behaviors prompts the need to examine whether measures of ineffective leadership developed in the United States are equivalent across countries outside the United States. B. J. Tepper's (2000) abusive supervision measure has been used widely inside and outside the United States and merits research attention on its construct equivalence across different cultural settings. The authors conducted a series of multigroup confirmatory factor analyses to investigate the measurement equivalence of this measure across Taiwan (N = 256) and the United States (N = 389). Configural invariance was established, suggesting that both U.S. and Taiwanese samples perceive abusive supervision as a single-factor concept. Furthermore, the establishment of partial metric invariance and partial scalar invariance suggests that the abusive supervision measure is applicable to crosscultural comparisons in latent means, construct variance, construct covariances, and unstandardized path coefficients with the caution that workers from different cultures calibrate their responses differently when answering some items.     

How Do Propensity Score Methods Measure Up in the Presence of Measurement Error? A Monte Carlo Study

Considering that the absence of measurement error in research is a rare phenomenon and its effects can be dramatic, we examine the impact of measurement error on propensity score (PS) analysis used to minimize selection bias in behavioral and social observational studies. A Monte Carlo study was conducted to explore the effects of measurement error on the treatment effect and balance estimates in PS analysis across seven different PS conditioning methods. In general, the results indicate that even low levels of measurement error in the covariates lead to substantial bias in estimates of treatment effects and concomitant reduction in confidence interval coverage across all methods of conditioning on the PS.     

On the validity of implicit association measures of personality traits

Participants (N = 200) completed self-report and implicit association (IAT) measures of Extraversion, Conscientiousness, and Emotional Stability. Peer trait ratings and supervisor ratings of job performance were also collected. Results suggested low convergence between IAT and self-report trait measures. Cognitive ability and self-positive bias both explained significant portions of the method variance expressed by IAT measures. Correlations between IAT trait measures and job performance were statistically non-significant, of similar magnitudes to their self-report counterparts, and of magnitudes consistent with past research on criterion validities of self-report trait measures. The results offer only very limited support for the use of IAT trait measures in applied assessment settings.     

Indirect scaling methods for testing quantitative emotion theories

Two studies investigated the utility of indirect scaling methods, based on graded pair comparisons, for the testing of quantitative emotion theories. In Study 1, we measured the intensity of relief and disappointment caused by lottery outcomes, and in Study 2, the intensity of disgust evoked by pictures, using both direct intensity ratings and graded pair comparisons. The stimuli were systematically constructed to reflect variables expected to influence the intensity of the emotions according to theoretical models of relief/disappointment and disgust, respectively. Two probabilistic scaling methods were used to estimate scale values from the pair comparison judgements: Additive functional measurement (AFM) and maximum likelihood difference scaling (MLDS). The emotion models were fitted to the direct and indirect intensity measurements using nonlinear regression (Study 1) and analysis of variance (Study 2). Both studies found substantially improved fits of the emotion models for the indirectly determined emotion intensities, with their advantage being evident particularly at the level of individual participants. The results suggest that indirect scaling methods yield more precise measurements of emotion intensity than rating scales and thereby provide stronger tests of emotion theories in general and quantitative emotion theories in particular.     

Measuring Spiritual Fitness: Atheist Military Personnel,Veterans, and Civilians

This study investigated the impact of transcendent item phrasing (i.e., phrasing which assumes the respondent believes in certain sacred or supernatural concepts) on the validity of the U.S. Army’s Comprehensive Soldier Fitness (CSF) program’s spiritual fitness scale when administered to atheist military personnel, veterans, and civilians. Results indicated that the inclusion of transcendent phrasing led to reduced concurrent validity for the spiritual fitness scale when administered to atheist military personnel and veterans, reduced concurrent and predictive validity when administered to atheists’ but not Christians’ spiritual fitness. Notably, the removal of transcendent phrasing actually led to increased concurrent validity for Christian respondents. Taken together, these findings suggest the Revised scale, which is composed of items that do not rely on transcendent phrasing, produces better psychometric outcomes for both atheist and Christian respondents. Implications for the CSF program and the measurement of spiritual fitness are addressed.     

Evaluation of the Religiosity in 5-D Scale

ABSTRACT

The goal of this study was to evaluate the factor structure and measurement equivalence of the Religiosity in 5-D Scale (Faulkner & DeJong, 1966). Using 262 participants from the Georgia Centenarian Study (Poon et al., 1992), analyses included exploratory factor analyses without rotation and using rotation, confirmatory factor analyses of a multiple and single factor religiosity construct, the establishment of measurement equivalence across age groups. The 5-D scale maintained a one-factor construct of religiosity. Dimensions of this factor included ideology, experience, ritual, and consequence. A measurement model of the religiosity construct was then established using summary scores. Confirmatory factor analysis revealed a satisfactory model of fit (GFI = .99; CFI = 1.00). Finally, measurement equivalence was maintained across age groups including sexagenarians (GFI = .95), octogenarians (GFI = .89), and centenarians (GFI = .95). The 5-D scale is an appropriate measure for use in aging research.     

The development and initial validation of the Fatigue Sensitivity Questionnaire

ABSTRACT

Currently, there is poor understanding of fatigue and the possible psychological conditions that may underlie chronic fatigue. Although substantial work has been directed to better clinically address fatigue, no work has explored individual differences in expectations or perceptions of the negative consequences associated with fatigue-related symptoms. The goals of this study were to (a) develop and (b) validate a measure of expectations or perceptions of the negative consequences associated with fatigue-related symptoms (e.g. fatigue sensitivity) across two independent samples (N = 1,827; 73.1% female; M_age = 21.68; SD = 4.54) of young adults. Results supported a 10-item measure of fatigue sensitivity, entitled the Fatigue Sensitivity Questionnaire (FSQ). The FSQ demonstrated unidimensionality, excellent internal consistency, and strong convergent and discriminant validity. Overall, the 10-item scale offers a single score that can be employed to measure fatigue sensitivity. Clinically, the FSQ may be a brief, informative, and easily disseminated measure in better understanding and capturing expectations or perceptions about the negative consequences of fatigue. As a research tool, the use of the FSQ may provide broader understanding of vulnerability factors that may influence fatigue-related health outcomes. Future research is needed to test the validity of the FSQ in other samples.

Abstract

The relationship between work and home-based stressors in predicting burnout symptoms was examined amongst 120 drug and alcohol service employees. Staff who reported high levels of burnout on the Maslach Burnout Inventory across all three scales of Emotional Exhaustion, Depersonalization and Personal Accomplishment were compared with a sample of low burnout employees. High burnout was associated with younger age, larger agency size, high levels of total work stressors, work overload, and daily hassles and a lower level of peer cohesion. Regression analyses revealed that male gender, younger age, work overload, role ambiguity and daily hassles were significant predictors of Emotional Exhaustion. Younger age was also a significant predictor of Depersonalization. Marked differences were found in the way in which males and females responded to work and non-work stressors and the interaction between these variables. For women, a significant interaction was found between total work stressors and home-based stressors in the prediction of Emotional Exhaustion and a trend in this direction was evident for Depersonalization. Low levels of home problems appeared to protect women from the adverse impact of work stressors. The burnout levels of women were relatively unaffected by work stressors, unless home stressors were also high. The level of daily hassles had a direct effect upon symptoms of Emotional Exhaustion, but did not interact with work stressors in predicting Emotional Exhaustion for women. Burnout levels of male employees on Emotional Exhaustion and Depersonalization scales were strongly linked to the level of work stressors and were not predicted by total home stressors nor the interaction between these variables. Symptoms of Emotional Exhaustion in males were predicted by severity of daily hassles, but this variable did not interact with work stressors in predicting Emotional Exhaustion.
