Development of the Multicultural Mental Health Awareness Scale

The present study describes the development of an instrument to assess the multicultural competencies of mental health professionals in Australia. The scale was developed to assess the effectiveness of a multicultural mental health training program. Mental health professionals from Queensland, Australia (N = 268) participated in the study by completing a questionnaire battery. Items on the new scale were generated to parallel the Queensland Transcultural Mental Health Centre (QTMHC) training program's objectives. The results describe a 35‐item Multicultural Mental Health Awareness Scale. Factor analysis of the scale indicated three factors of multicultural counselling competencies: Awareness, Knowledge, and Skills. These factors were in line with the Sue et al. (1982) multicultural counselling competencies. The scale has satisfactory internal consistency, test–retest reliability, concurrent validity, and discriminant validity and can be used to evaluate the effectiveness of the multicultural competency training programs in mental health.     

Reliability of Summed Item Scores Using Structural Equation Modeling: An Alternative to Coefficient Alpha

A method is presented for estimating reliability using structural equation modeling (SEM) that allows for nonlinearity between factors and item scores. Assuming the focus is on consistency of summed item scores, this method for estimating reliability is preferred to those based on linear SEM models and to the most commonly reported estimate of reliability, coefficient alpha.     

Parent and Teacher Ratings of Attention-Deficit/Hyperactivity Disorder in Preschool: The ADHD Rating Scale-IV Preschool Version

Efforts for early identification and intervention for children with AD/HD have necessitated the development of rating scales of behavior for the preschool population. The standardization, reliability, and validity data were presented for the ADHD Rating Scale-IV Preschool Version. Parent and teacher ratings were collected on 902 and 977 children 3 to 5 years of age, respectively. Raw scores for the Inattention, Hyperactivity/Impulsivity and Total scores were converted to T-Scores and percentile ranks. Reliability coefficients ranged from 0.80 to 0.95 indicating good test–retest reliability. Concurrent validity with the Conners Teacher Rating Scales: Revised-Short and Conners Parent Rating Scale: Revised-Short ranged from 0.54 to 0.96. The ADHD-Rating Scale-IV appears to be a reliable, valid and user friendly measure for screening preschoolers with behavior problems. Future research is needed to validate its widespread use as a screening and diagnostic tool.     

Slower eating rate reduces the food intake of men, but not women: implications for behavioral weight control

This study tested a central tenet of behavioral weight control: does slower eating rate reduce food intake and positively affect appetite ratings. This study used direct behavioral observation of participants' (n=48; 25BMI35) eating behavior using Universal Eating Monitors. Food intake and ratings of "desire to eat" (collected each minute during meals) were represented as a function of time. Based on an acclimation meal, participants' eating rate was modified by instructing them to eat a bite of food when prompted by a computer, which generated three types of meals: (1) baseline (eating rate was the same as the acclimation meal), (2) reduced-rate (eating rate was reduced by 50%), and (3) combined-rate (eating rate at the beginning of the meal was identical to that of the acclimation meal, subsequently eating rate was reduced by 50%). All meals were ad libitum. Slower eating rate during the reduced-rate and combined-rate meals resulted in less food intake compared to the baseline meal for men, but not women. Ratings of desire to eat, normalized for the amount of food consumed, were lower during the combined-rate meal for men and women. Thus, this basic premise of behavioral weight control was supported for men, but not for women.     

On the measurement of preferences in the analytic hierarchy process

In this paper we apply multiattribute value theory as a framework for examining the use of pairwise comparisons in the analytic hierarchy process (AHP). On one hand our analysis indicates that pairwise comparisons should be understood in terms of preference differences between pairs of alternatives. On the other hand it points out undesirable effects caused by the upper bound and the discretization of any given ratio scale. Both these observations apply equally well to the SMART procedure which also uses estimates of weight ratios. Furthermore, we demonstrate that the AHP can be modified so as to produce results similar to those of multiattribute value measurement; we also propose new balanced scales to improve the sensitivity of the AHP ratio scales. Finally we show that the so-called supermatrix technique does not eliminate the rank reversal phenomenon which can be attributed to the normalizations in the AHP. © 1997 John Wiley & Sons, Ltd.     

Comparison of the construct validity of the Gray–Wilson Personality Questionnaire and the BIS/BAS scales

345 subjects completed a translated, shortened version of the Gray–Wilson Personality Questionnaire (GWPQ), along with Russian versions of Carver and White’s BIS/BAS scales, the Eysenck Personality Profiler, the Eysenck Personality Questionnaire, and Spielberger’s State-Trait Anxiety Inventory. Exploratory factor analysis of GWPQ items pointed to a three-factor solution and three new scales were created which demonstrated adequate psychometric characteristics. Confirmatory factor analysis of the BIS/BAS scales showed that a four-factor model best fitted the data but the three BAS subscales should be treated as sub-factors of a second-order factor. Structural equation modelling showed that GWPQ scales generally explained Eysenck’s dimensions better than BIS/BAS scales. The distinction between GWPQ and Carver and White’s scales mainly concerned BAS measures. GWPQ BAS captured more of Psychoticism, whereas Carver and White’s BAS captured more of Extraversion.     

Vocal mistuning reveals the origin of musical scales

ABSTRACT

Theories of the origin of tonality from the time of Pythagoras onward have assumed that the intervals used in musical scales are defined mathematically based on harmonic ratios. Virtually all such theories are predicated on tunable instruments (e.g. strings), whereas the voice is the most ancestral and universal instrument used to make music. In the present study, we analysed the tuning of sung musical intervals from a familiar song, doing so across both trained and untrained singers. Contrary to the predictions of traditional theories, we found that sung intervals (unlike those of instruments) showed marked overlap with neighbouring interval categories. Furthermore, we found that listeners of these sung productions did not base their aesthetic judgments of singing quality on the precision of tuning of sung intervals. We consolidate these results into a model of tonality based on both vocal and sensory factors that contribute to the formation of sung melodies.     

Item Response Theory Analyses of the Parent and Teacher Ratings of the DSM-IV ADHD Rating Scale

The graded response model (GRM), which is based on item response theory (IRT), was used to evaluate the psychometric properties of the inattention and hyperactivity/impulsivity symptoms in an ADHD rating scale. To accomplish this, parents and teachers completed the DSM-IV ADHD Rating Scale (DARS; Gomez et al., Journal of Child Psychology and Psychiatry, 40, 265–274, 1999) for a group of 1,475 primary school-aged children. The results for the discrimination parameters showed that all symptoms for both groups of respondents were generally good for discriminating their respective latent traits. For virtually all symptoms, their threshold values showed moderate to large increases in the level of the latent trait at each subsequent response dichotomy, with the symptoms being especially good at representing the appropriate traits from mean to moderately high trait levels. The item information function values for most symptoms indicated reasonable reliability from, approximately, the mean trait levels to moderately high trait levels. These findings indicate good psychometric properties for the parent and teacher ratings of the DARS. The implications of the findings for the use of the DARS and other similar scales are discussed.     

The personality basis of justice: The five‐factor model as an integrative model of personality and procedural fairness effects on cooperation

Building upon the self‐based model of cooperation (De Cremer & Tyler, 2005 ), the present study investigates the relationship between the five‐factor model (FFM) and cooperation. Study 1 (N = 56), an experiment conducted in the laboratory, and Study 2 (N = 116), a field study conducted in an organisational context, yielded a moderator effect between neuroticism and procedural fairness in explaining cooperation. Study 3 (N = 177) showed that this moderator effect was mediated by the self‐uncertainty and relational variables proposed by the self‐based model of cooperation. It is concluded that the FFM is useful in explaining cooperation and contributes to a better understanding of (procedural) fairness effects. Moreover, the necessity to build integrative, multi‐level models that combine core and surface aspects of personality to explain the effects of fairness on cooperation is elaborated upon.
