Disentangling prototypicality and social desirability: the case of the KNOWI task

The prototype of indicators of a relationship partner who can be trusted to be responsive at times of stress is one kind of social knowledge structure. The Knowledge of Indicators (KNOWI) Task assesses individual differences in knowledge about these prototypic indicators. In constructing the KNOWI, an iterative procedure was used in an attempt to identify those indicators for which ratings of prototypicality are not influenced by social desirability. Study 1 demonstrated that the correlation between ratings of prototypicality and social desirability is indeed eliminated for the final set of indicators retained in the KNOWI. Study 2 tested the prototype matching hypothesis: Comparing an actual partner to the prototype might shape global judgments about that partner's responsiveness. Because in Study 2 only those indicators that are uncorrelated with social desirability were used, this result cannot be explained by social desirability. These results support the construct validity of the indicators used in the KNOWI Task, which seems to be a precise assessment tool not influenced by social desirability.     

Factorial validity of the Conners' Parent Rating Scale-revised: short form with psychiatric outpatients

To assess the factorial validity of the 27-item Conners' Parent Rating Scale-Revised: Short Form (CPRS-R:S; Conners, 1997), 100 (50%) male and 100 (50%) female psychiatric outpatients between 5 and 16 years old were rated by a parent. A confirmatory factor analysis of the 18 item ratings from the CPRS-R:S Oppositional, Cognitive Problems, and Hyperactivity scales provided only tentative support for scoring these scales as Conners (1997) recommended. However, an exploratory principal-axis factor analysis with all 27 item ratings found 2 dimensions: 1 dimension was composed of the 6 items in the Oppositional scale, and other dimension contained the remaining 21 items. An attention deficit hyperactivity disorder (ADHD) Total Symptoms scale was constructed by summing the ratings for these 21 symptom ratings, and this scale was found to be as effective as the Hyperactivity scale was in discriminating between youth who were and were not eventually diagnosed with an ADHD. We discuss the results as providing an alternate way of scoring the CPRS-R:S to screen for an ADHD in child and adolescent psychiatric outpatients.     

Acts and dispositions: A reconsideration of the Act Frequency Approach

The Act Frequency Approach (AFA) proposed by Buss and Craik was summarized and critically reviewed on the basis of a German replication study using six interpersonal traits each with 100 translated acts. The six traits studied were dominant, gregarious, agreeable, submissive, aloof, and quarrelsome. The internal structure of these categories was examined via multiple prototypicality ratings. It was demonstrated that many acts are highly prototypical for more than one category. The manifested categorical structure was tested by gathering retrospective act reports about performance and frequency of exhibiting each of these 600 acts using a sample of 213 adults. Aggregation of the acts according to their prototypicality key yielded reliable subscales. The validities obtained on the basis of the 25 highly prototypical acts were slightly higher compared with those of the 100 act set, as well as the sets with lower prototypicality. The validity gradient proposed by Buss and Craik was found using selected personality scales as well as global self-ratings and peer-ratings on some of the respective trait terms. In general, the results of the German study replicated the findings of Buss and Craik.     

An investigation of the psychometric properties of the MMPI-2 Restructured Clinical (RC) scales with mental health inpatients

In this study, we compared the internal psychometric properties and external correlates of the MMPI-2 (Butcher et al., 2001; Tellegen et al., 2003) Restructured Clinical (RC) scales and corresponding MMPI-2 non-K-corrected Clinical scales in a sample of 280 men and 264 women admitted to inpatient psychiatric units. We evaluated the internal psychometric properties of the RC and Clinical scales by intercorrelation analyses and alpha coefficients. We investigated external correlates of scores from the RC and Clinical scales using selected chart variables, selected Symptom Checklist 90-Revised (Derogatis, 1983, 1994) items, and clinician ratings on the Brief Psychiatric Rating Scale (Overall & Gorham, 1988). Results showed psychometric support for the RC scales in terms of improved intercorrelation patterns and comparable or greater alpha coefficients. Further, external correlational analyses revealed varying degrees of evidence of improvement in convergent and discriminant validity.     

Development of a prototype‐based measure of relational boredom

The goal of this research was to create a self‐report measure of relational boredom using a prototype approach. In the first study, 2 samples (participants in dating relationships and in marital relationships) generated features of the concept of relational boredom. In Study 2, these features were rated for prototypicality by 2 samples (dating and married). A Relational Boredom Scale was constructed by selecting those features (items) that were rated as most central to the construct. In Study 3, the reliability and validity of the scale were assessed, again with participants in dating and marital relationships. There was evidence that the Relational Boredom Scale is a psychometrically sound measurement instrument.     

Prototypicality norms for 28 semantic categories

The extent to which an item is a prototypical exemplar of a category has been found to predict several experimental results (e.g., reaction times in category classification, free and cued recall of lists, release from proactive inhibition in recall). We present prototypicality ratings for 840 words, equally distributed over 28categories. Thecategories were taken from Battig and Montague’s (1969) normative tables; only those categories that contained “concrete” items in common usage were employed in the study. Intragroup reliability correlations were high for all categories tested, as were the correlations for prototypicality ratings between the present study and that of Rosch (1975). In addition, correlations between prototypicality ratings, production frequencies, and word frequencies of the items are given.     

Using generalizability theory to estimate the relative effect of class size and number of items on the dependability of student ratings of instruction

Previous research on the effect of class size on student ratings of instruction has primarily investigated the effect of class size on the favorableness of these ratings rather than its effect on their reliability (dependability). A few studies have used "generalizability theory" to demonstrate the relative effect of class size on the dependability of student ratings of instruction. The purpose of the present study was to test the validity of the findings of these studies in a different cultural setting using a different student ratings questionnaire. Using a random-effect analysis of variance to estimate the variance components for a design in which students were nested within classes and crossed with items, it was found that the variance component for class size was appreciably larger than that for items. At least 20 students were needed to obtain a generalizability coefficient for relative decisions of .70 or more. Increasing the number of students has a greater effect on generalizability coefficients than increasing the number of items.     

A depressive symptom scale for the California Psychological Inventory: construct validation of the CPI-D

To facilitate life span research on depressive symptomatology, a depressive symptom scale for the California Psychological Inventory (CPI) is needed. The authors constructed such a scale (the CPI-D) and compared its psychometric properties with 2 widely used self-report depression scales: the Beck Depression Inventory and the Center for Epidemiological Studies Depression Scale. Construct validity of the CPI-D was examined in 3 studies. Study 1 established content validity, classifying CPI-D items into Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition depressive symptoms. Study 2 used 3 large samples to gather evidence for reliability and validity: correlational analyses demonstrated alpha reliability and convergent and discriminant validity; factor analysis provided evidence for discriminant validity with anxiety; and regression analyses demonstrated comparative validity with existing standard PI scales. Study 3 used clinician ratings of depression and anxiety as criteria for external validity.     

Family resemblances: Studies in the internal structure of categories

Six experiments explored the hypothesis that the members of categories which are considered most prototypical are those with most attributes in common with other members of the category and least attributes in common with other categories. In probabilistic terms, the hypothesis is that prototypicality is a function of the total cue validity of the attributes of items. In Experiments 1 and 3, subjects listed attributes for members of semantic categories which had been previously rated for degree of prototypicality. High positive correlations were obtained between those ratings and the extent of distribution of an item's attributes among the other items of the category. In Experiments 2 and 4, subjects listed superordinates of category members and listed attributes of members of contrasting categories. Negative correlations were obtained between prototypicality and superordinates other than the category in question and between prototypicality and an item's possession of attributes possessed by members of contrasting categories. Experiments 5 and 6 used artificial categories and showed that family resemblance within categories and lack of overlap of elements with contrasting categories were correlated with ease of learning, reaction time in identifying an item after learning, and rating of prototypicality of an item. It is argued that family resemblance offers an alternative to criterial features in defining categories.     

Developing the Impulsive Driver Behavior Scale

The aim of the present study is to develop a driving context specific impulsivity scale. First, a qualitative study was conducted by interviewing 20 individual drivers to develop the scale items based on the definitions of the basic impulsivity dimensions in the literature. Then, a quantitative study with a total of 506 individual drivers to examine the psychometric qualities of the newly developed Impulsive Driver Behavior Scale. In addition, the variance in driver behaviors, namely violations, errors, lapses and positive driver behaviors measured by the Driver Behavior Questionnaire (DBQ; Reason, Manstead, Stradling, Baxter, & Campbell, 1990) explained by the general impulsivity scales in the literature and the newly developed scale were compared. In all the comparisons, Impulsive Driver Behavior Scale explained higher amount of variance than the general impulsivity scales. Finally, it was found that the newly developed driving context specific impulsivity scale had incremental validity over the general impulsivity scales in predicting driver behaviors.     

Measuring personality in one minute or less: A 10-item short version of the Big Five Inventory in English and German

To provide a measure of the Big Five for contexts in which participant time is severely limited, we abbreviated the Big Five Inventory (BFI-44) to a 10-item version, the BFI-10. To permit its use in cross-cultural research, the BFI-10 was developed simultaneously in several samples in both English and German. Results focus on the psychometric characteristics of the 2-item scales on the BFI-10, including their part-whole correlations with the BFI-44 scales, retest reliability, structural validity, convergent validity with the NEO-PI-R and its facets, and external validity using peer ratings. Overall, results indicate that the BFI-10 scales retain significant levels of reliability and validity. Thus, reducing the items of the BFI-44 to less than a fourth yielded effect sizes that were lower than those for the full BFI-44 but still sufficient for research settings with truly limited time constraints.     

Leadership and Perceiver Cognition: Examining the Role of Self-Identity in Implicit Leadership Theories

We investigated whether priming individuals' self-identities to be interdependent or independent influences their ratings of leadership prototypicality. Specifically, we predicted that participants receiving an interdependent prime would rate items associated with transformational leadership as being more prototypical of effective leadership than would participants receiving no prime. We also predicted that participants receiving an independent prime would rate transactional leadership items as being more prototypical of effective leadership. Undergraduate psychology students were randomly assigned to one of three conditions (interdependent prime, independent prime, and control). Results support the idea that self-identity can be primed to influence ratings of leadership prototypicality. We discuss implications and suggest directions for future research.     

Validation of the Treatment Motivation Scales for Forensic outpatient treatment (TMS-F)

The validity of the Treatment Motivation Scales for outpatient offender treatment (TMS-F), a self-report questionnaire with scales for the motivation of patients to engage in the treatment and six cognitive and emotional determinants of this motivation, is evaluated in two studies. In Study 1 (N = 620), the construct validity of the TMS-F is investigated applying a multitrait-multimethod design with a therapist-rating instrument as the criterion method. All scales were found to have adequate convergent validity and acceptable discriminant validity. In Study 2 (N = 328), the criterion validity of the TMS-F is addressed. Applying covariance structure analysis, the instrument is found to predict therapist ratings of the treatment engagement of patients to a substantial degree. Treatment engagement is best predicted by the scales for Motivation to Engage in the Treatment and Perception of the Suitability of the Treatment and not by the scales for Distress and the Perceived Legal Pressure.     

Construction and validation of a physician career development inventory

The development and psychometric characteristics of the Medical Career Development Inventory (MCDI) are described. The MCDI represents the initial construction of a career maturity measure for a homogeneous population of adults who encounter a common set of vocational development tasks. The inventory is intended to measure both degree of vocational development and readiness to cope with the developmental tasks encountered in a physician's career. The MCDI includes 35 items that address coping behaviors germane to dealing with the vocational tasks constituting the career development continuum of physicians. Initial evaluation of the MCDI's psychometric properties with a sample of 160 student-physicians supported the content validity of the items, construct validity of the scales, and criterion validity of the inventory.     

Conceptual and measurement issues of the complementarity dimension of the coach–athlete relationship across cultures

ObjectivesGrounded in the 3Cs model of the coach–athlete relationship, this multi-study outlined the development of two scales that measure coaches' dominant behaviors and athletes' submissive behaviors.Method & resultsIn study 1, a pool of items was generated based on relevant literatures and interviews. The item pool was then assessed by an expert panel including academics, athletes and coaches. In Study 2 and Study 3, construct and criterion validity, as wells as internal reliability of the refined items were tested with a sample of elite coaches and athletes. Analyses revealed that Coach Dominant Behavior Scale (CDB-S) and Athlete Submissive Behavior Scale (ASB-S) possessed sound psychometric properties. In Study 4, the measurement invariance of the 10-item ASB-S was assessed across gender and five countries: Britain, China, Greece, Spain, and Sweden. Results supported the full structural invariance of the ASB-S.ConclusionOverall, the items of both CDB-S and ASB-S were found to be psychometrically sound. The discussion highlights the contributions these findings make on both conceptual and measurement levels as well as the opportunities it opens up for research with practical relevance.     

When Less is More: A Short Version of the Personal Optimism Scale and the Self-Efficacy Optimism Scale

The past few years have seen increased theoretical and applied research on the relations between constructs related to positive expectations. However, instruments capable of distinguishing positive expectancy constructs are still lacking. This study evaluated the psychometric properties of the 18-item Personal Optimism Scale and Self-Efficacy Optimism Scale. Two student samples from the University of Novi Sad in Serbia were recruited for the present research, with a total of 728 participants. The results of the exploratory and confirmatory factor analyses did not support the theoretically expected structure. The results of the confirmatory factor analysis and content validity support shortening the scale to 9 items. The short versions of the scales demonstrated adequate reliability in internal consistency and adequate concurrent and convergent validity by significant correlations with dispositional optimism, general self-efficacy, hope, resilience and subjective well-being. The analyses lead us to conclude that a shorter 4-item Personal Optimism Scale and a 5-item Self-Efficacy Optimism Scale provide a clear, precise measures of two types of positive expectations. The authors argue that the limitations of the original scales emanate from their vague theoretical-substantive validity, and call for future research to replicate these findings.     

Validation of the French version of Brandtstädter and Renner's Tenacious Goal Pursuit (TGP) and Flexible Goal Adjustment (FGA) scales

IntroductionDespite the potential usefulness of the TGP/FGA scales (Brandtstädter and Renner, 1990) for studying the way people adapt with age, there is little psychometric evidence supporting the validity of the construct of either scale.ObjectiveThe aim of the study was to develop a French version of Brandtstädter's TGP/FGA scales in order to provide a self-report measure for French people in the field of gerontology.MethodTwo studies involving 677 participants were conducted to evaluate the construct validity, reliability and convergence validity of these scales.ResultsIn accordance with Brandtstädter, two factors emerged from the exploratory factorial analysis (study 1): tenacious goal pursuit and flexible goal adjustment. However, 10 items were removed because of factorial loadings. A confirmatory factor analysis (study 2) of the 20 remaining items corroborated a two-factor uncorrelated model of the TGP/FGA scales. The simplified subscales showed good internal consistency. As expected, higher scores on the TGP/FGA scales were correlated with good life satisfaction, greater control and less depression. Finally, the TGP scale was negatively related to age, but the FGA was not.ConclusionThe French adaptation of the TGP/FGA scales was shown to possess satisfactory psychometric properties and may therefore be a valuable instrument for researchers and clinicians who are interested in exploring adaptive processes in the maintenance and promotion of personal well-being.
