Attribute-value functions as global interpretations of attribute importance

In order to better understand decision maker’s perceptions of the importance of attributes, Goldstein (1990) differentiates between global and local interpretations of attribute importance. While the appreciation for the distinction is growing, research on the relationship between measures of global and local importance is inconclusive. We believe that these inconclusive findings are caused by operationalizing global attribute importance with single-point measures that implicitly assume that the global interpretation of attribute importance linearly depends on the relevant range of context-specific attribute levels. To address this, we propose to operationalize the global interpretation of attribute importance by estimating decision makers’ attribute-value functions. Two empirical studies demonstrate that the shape of attribute-value functions changes from concave to convex with global attribute importance. Furthermore, the steepness of these functions increases with global attribute importance while the diminishing sensitivity decreases. Finally, it is demonstrated that the inconclusive findings about the relationship between common, single-point measures of global and local attribute importance is driven by non-linearities in decision makers’ attribute-value functions. The results suggest great promise for future research on using decision makers’ attribute-value functions for measuring the importance of attributes.     

Factor structure and measurement invariance of a short measure of the Big Five personality traits

The main purpose of this study is to assess the factor structure and the measurement invariance of the Mini-International Personality Item Pool (Mini-IPIP; Donnellan, Oswald, Baird, & Lucas, 2006). The Mini-IPIP is a brief instrument evaluating personality traits according to the Big Five models. Two samples were collected comprising nearly 800 participants. Confirmatory factor analyzes revealed a five-factor solution consistent with the Big Five model. Measurement invariance analyses showed that the Mini-IPIP was reasonably invariant across samples, genders and age groups. Overall, results pointed to a satisfactory factorial structure and an adequate invariance of the measure.     

Cross-sectional and longitudinal confirmatory factor models for the german test anxiety inventory: A construct validation

Construct validity of the German Test Anxiety Inventory (TAI-G) was tested in two respects. Firstly, the purported four-dimensional structure of the TAI-G (comprising subscales Emotionality, Worry, Interference, and Lack of Confidence) as well as relations of the test anxiety dimensions to self-efficacy were tested. Secondly, the trait conception of the TAI-G was tested within the framework of Latent State-Trait theory. The TAI-G was given to a student sample (N=302) on three occasions with a time interval of 2 weeks along with a study-specific self-efficacy scale on occasion 1. Dimensionality assumptions as well as relations with self-efficacy were tested using cross-sectional second-order confirmatory factor analysis. The trait conception was tested separately for TAI-G subscales by specifying longitudinal confirmatory factor models (Latent State-Trait models) and by calculating variance proportions of manifest variables (Latent State-Trait coefficients) referring to different sources of systematic variance (person, situation, and method) based on parameter estimates of the models. Results were supportive of both the purported four-dimensional structure and hypothesized relationships to self-efficacy (i.e., acceptable model fit) as well as of the trait conception of test anxiety (i.e., acceptable model fit and high proportion of variance due to person component). Implications for further validation studies were discussed.     

Towards a theory-based assessment of coping: The german adaptation of the strategic approach to coping scale

Although coping has become one of the central constructs in the area of research on life events, emotions, and health, it is yet not clear how to conceptualize coping in the most powerful way. Coping instruments often lack a clear underlying theory or are confounded with the stress process itself. Therefore, a theoretical as well as empirical framework is needed. The study at hand presents cross-sectional data from a German version of a coping scale that is constructed in line with the Strategic Approach to Coping Scale (SACS) developed by Hobfoll et al. The German scale findings support those of the original, US version, but also indicate potential cultural distinction. The findings suggest that the GSACS is theory syntonic and has potential for elaborating coping research.     

The Reliability,Validity, Discriminant and Predictive Properties of the Social Phobia Inventory (SoPhI)

This paper reports on the psychometric properties of the Social Phobic Inventory (SoPhI) a 21-item scale that was designed to measure social anxiety according to the criteria of DSM-IV (American Psychiatric Association, APA (1994) Diagnostic and Statistical Manual of Mental Disorder , 4th Edn., Washington). Factor analysis of the SoPhI using data from a clinical sample of respondents with social phobia revealed one factor which explained approximately 59% of variance and which demonstrated strong internal reliability ( f = 0.93). The SoPhI demonstrated concurrent validity with the SPAI ( r = 0.86) and convergent validity with the Fear of Negative Evaluations-Revised ( r = 0.68). The predictive utility of the scale was demonstrated in a sample of university students classified as extroverted, normal, shy/introverted, and phobic/withdrawn ( m 2 57%). Multivariate Analysis of Variance (MANOVA) revealed that the combined university sample differed from the clinical sample on the summated scores on the SoPhI and that 43% ( m 2 ) of this difference was attributable to group membership. This figure rose to 58% attributable to group membership when these same groups were compared for differences on the 21 individual items. Scores of the SoPhI that are indicative of concern and of possible diagnostic criteria, as well as suggestions for future research, are discussed.     

Construct and Criterion Validity of the Comprehensive Trail Making Test in Children and Adolescents with Traumatic Brain Injury

The current study examined the construct and criterion validity of the Comprehensive Trail Making Test (CTMT) when used to evaluate children and adolescents with traumatic brain injury (TBI). Participants included 100 children and adolescents, 50 who had sustained TBI and 50 normal comparisons (NC). Analyses indicated that the CTMT factor scores were significantly correlated with tests of perceptual organizational ability, processing speed, and motor function and provided support for its construct validity. Additionally, correlations between the various CTMT scores suggested that a different pattern of associations was present in the TBI group compared to the NC group. Finally, the TBI group performed significantly worse (p < .001) on all of the CTMT scores, including each of the five CTMT trails as well as the factor and composite index scores. Results support the construct and criterion validity of the CTMT when used to assess children and adolescents with TBI.     

Children and the Test of Memory Malingering: Is one trial enough?

There is a growing body of research suggesting that the first trial of the TOMM may provide an accurate screener of effort in children. During neuropsychological assessments, some circumstances result in only one completed trial of the TOMM. Research on adults reflects that passing scores on Trial 1 (based on Trial 2 cutoff) are highly predictive of passing scores on Trial 2 and the TOMM overall. Pediatric research found that 100% of children and adolescents who passed Trial 1 of the TOMM also passed Trial 2. Our research hypothesis is that children who pass Trial 1 will also pass Trial 2. Data from 75 clinically diagnosed children (ages 6–18 years) found that 64% performed above the published adult TOMM cutoff on Trial 1. All children who passed Trial 1 also passed Trial 2 suggesting support for the research hypothesis. Sensitivity was 1.0, specificity was 0.72, positive predictive value was .33, and negative predictive value was 1.0. These findings suggest that in this sample, the children who performed above the Trial 2 cutoff on Trial 1 also all passed Trial 2 (so there were no false negatives, thus a perfect sensitivity and negative predictive value). Of the 36% of children who did not pass the Trial 1 cutoff, 67% passed on Trial 2. Data clearly support that children passing Trial 1 have a high likelihood of passing Trial 2, thus drawing conclusions about performance validity after passing Trial 1. Conclusions after failing Trial 1 require further investigation.     

Development and psychometric properties of a new measure for memory phenomenology: The Autobiographical Memory Characteristics Questionnaire

The purpose of this study is to develop a valid and reliable measure for the phenomenology of autobiographical memories. The psychometric properties of the Autobiographical Memory Characteristics Questionnaire (AMCQ) were tested in three studies: the factor structure of the AMCQ was examined for childhood memories in Study 1 (N = 305); for autobiographical memories related to romantic relationships in Study 2 (N = 197); and for self-defining memories in Study 3 (N = 262). The explanatory factor analyses performed for each memory type demonstrated the consistency of the AMCQ factor structure across all memory types; while a confirmatory factor analysis on the data garnered from all three studies supported the constructs for the autobiographical memory characteristics defined by the researchers. The AMCQ consists of 63 items and 14 factors, and the internal consistency values of all 14 scales were ranged between .66 and .97. The relationships between the AMCQ scales related to gender and individual emotions, as well as the intercorrelations among the scales, were consistent with both theoretical expectations and previous findings. The results of all the three studies indicated that this new instrument is a reliable and robust measure for memory phenomenology.
