Validation of the Multidimensional Schizotypy Scale-Brief in Two Large Samples

This study reports on an initial examination of the construct validity of the Multidimensional Schizotypy Scale-Brief (MSS-B) and the first investigation of its psychometric properties outside of its derivation samples. The MSS-B contains 38 items that assess positive, negative, and disorganized schizotypy and has comparable content coverage and psychometric properties as the original 77-item Multidimensional Schizotypy Scale. Two large samples (n?=?1430 and 1289) completed the MSS-B, as well as measures of schizotypal personality traits and the Five-Factor Model of Personality. MSS-B scores were computed from the full-length scale in sample 1, whereas participants in sample 2 were administered the MSS-B. The psychometric properties and intercorrelations of the MSS-B subscales were consistent with findings from the original derivation samples, with no shrinkage in reliability. In terms of relations with schizotypal traits, the MSS-B positive schizotypy dimension had its strongest association with cognitive-perceptual schizotypal traits, MSS-B negative schizotypy had its strongest association with interpersonal schizotypal traits, and MSS-B disorganized schizotypy had its strongest association with disorganized schizotypal traits. The schizotypy dimensions were characterized by hypothesized patterns of distinct associations with the Five-Factor Model. The present findings are consistent with results from the full-scale MSS.     

Validation of the Multidimensional Blood/Injury Phobia Inventory: Evidence for a Unitary Construct

The Multidimensional Blood/Injury Phobia Inventory (MBPI) was developed from a theoretical framework to characterize a broad range of feared stimuli and phobic reactions associated with this pathology. The MBPI consists of 40 items that cross 4 types of stimulus content (injections, hospitals, blood, injury), 5 types of phobic responses (fear, avoidance, worry, fainting, disgust), and a self versus other focus. This study reports on administration of the MBPI to 558 undergraduates, 9 of whom had blood/injury phobia. The instrument had a Cronbach's alpha of .91 and demonstrated good concurrent validity, convergent validity, and discriminant validity. One large factor emerged in an unrotated principal components analysis, suggesting that blood/injury phobia is a unitary psychometric construct. Exploratory factor analyses revealed a 6-factor solution defined by stimulus content domains and fainting, each of which may be important to consider clinically when assessing the unique concerns of treatment-seeking individuals.     

Application of a Multidimensional Nested Logit Model to Multiple-Choice Test Items

Nested logit models have been presented as an alternative to multinomial logistic models for multiple-choice test items (Suh and Bolt in Psychometrika 75:454–473, 2010) and possess a mathematical structure that naturally lends itself to evaluating the incremental information provided by attending to distractor selection in scoring. One potential concern in attending to distractors is the possibility that distractor selection reflects a different trait/ability than that underlying the correct response. This paper illustrates a multidimensional extension of a nested logit item response model that can be used to evaluate such distinctions and also defines a new framework for incorporating collateral information from distractor selection when differences exist. The approach is demonstrated in application to questions faced by a university testing center over whether to incorporate distractor selection into the scoring of its multiple-choice tests. Several empirical examples are presented.     

The Meaning and Measurement of Work Ethic: Construction and Initial Validation of a Multidimensional Inventory

This monograph presents a brief historical and conceptual review of the work ethic construct, suggests a general conceptual definition of work ethic, and reports a series of empirical studies to construct and evaluate a new multidimensional measure of work ethic. The Multidimensional Work Ethic Profile (MWEP) is a 65-item inventory that measures seven conceptually and empirically distinct facets of the work ethic construct. A series of six studies, using both student and nonstudent samples, examined the psychometric properties of the MWEP. The first study replicates previous research demonstrating the multidimensionality of the work ethic construct. The second study describes the construction and initial psychometric evaluation of the MWEP. The third study examines relations between the MWEP subscales as well as relations with measures of general cognitive ability, personality, and manifest needs. The fourth study examines the generalizability of the MWEP from a student sample to a nonstudent working sample. The fifth study provides further evidence about the generalizability of the MWEP to an organizational sample and examines the relations of the MWEP subscales to other organizationally relevant attitudinal variables (i.e., job satisfaction, organizational commitment, and job involvement). Finally, the sixth study examines the criterion-related validity of the MWEP scales in an organizational context. Implications and directions for future research are discussed.     

Confirmatory Factor Analysis and Multidimensional Scaling for Construct Validation of Cognitive Abilities

Although factor analysis is the most commonly-used method for examining the structure of cognitive variable interrelations, multidimensional scaling (MDS) can provide visual representations highlighting the continuous nature of interrelations among variables. Using data (N = 8,813; ages 17-97 years) aggregated across 38 separate studies, MDS was applied to 16 cognitive variables representative of five well-established cognitive abilities. Parallel to confirmatory factor analytic solutions, and consistent with past MDS applications, the results for young (18-39 years), middle (40-65 years), and old (66-97 years) adult age groups consistently revealed a two-dimensional radex disk, with variables from fluid reasoning tests located at the center. Using a new method, target measures hypothesized to reflect three aspects of cognitive control (updating, storage-plus-processing, and executive functioning) were projected onto the radex disk. Parallel to factor analytic results, these variables were also found to be centrally located in the cognitive ability space. The advantages and limitations of the radex representation are discussed.     

Confirmatory Factor Analysis of Multitrait-Multimethod Data: The Construct Validation of Multidimensional Self-Concept Responses

ABSTRACT The multitrait-multimethod (MTMM) design is frequently used to test construct validity and is particularly appropriate for evaluating multidimensional instruments in personality research Despite its popularity there are important problems with both the traditional and confirmatory factor analysis (CFA) approaches to MTMM data In previous research (1989a, 1989b) I described a new CFA approach that I claimed to be relatively immune to many of these problems This approach is applied here to test the construct validity of preadolescent responses to three multidimensional self-concept instruments The substantive contribution of the present investigation is to demonstrate good support for the construct validity of two of the three instruments The methodological contributions are to further substantiate my claims about the new CFA approaches and to demonstrate this approach in a substantively meaningful context that has broad applicability to other personality research     

The Space Between in Group Psychotherapy: Application of a Multidimensional Model of Relationship

An 8-dimensional model of interpersonal relatedness, derived from existing theories of relationship as well as a phenomenological study, is applied to understanding the space between people in group therapy. Relational development is conceptualized as parallel streams of growth along separate dimensions, which may involve stronger relational capacities on some dimensions and weaker and more problematic behavior on others. This model is used to reflect on the group therapy situation in terms of how people are trying to connect with one another. Examples are offered and suggestions made for how the group therapist might be alert to the manifestations of each dimension. The goal is for both patients and therapist to have an enlarged view of what people need from one another and how to go about receiving it.     

The Family Impact of Pain Scale: Preliminary Validation

A new questionnaire, the Family Impact of Pain Scale (FIPS), was designed in order to assess the effects of chronic pain on the significant other and family of the chronic pain patient. The FIPS is a 10-item self-report questionnaire examining the effect of pain on domestic duties, social functioning and communication within the family. It was administered to 177 chronic pain patients in two different samples to investigate its psychometric properties. Internal reliability (α = .94) and test–retest reliability (r = 0.79) were high. Exploratory factor analysis suggested a two-factor solution, relating to physical limitations and difficulties with communication. Construct validity was confirmed by significant Pearson correlations with pain intensity, pain distress, mood and the use of pain coping skills (r = −0.22–0.74, all at p < .05). Outcome data also showed that the measure is sensitive to the effects of a cognitive behavioural pain management intervention.     

Development and Preliminary Validation of a Self-Report Measure of Psychopathic Personality Traits in Noncriminal Population

Research on psychopathy has been hindered by persisting difficulties and controversies regarding its assessment. The primary goals of this set of studies were to (a) develop, and initiate the construct validation of, a self-report measure that assesses the major personality traits of psychopathy in noncriminal populations and (b) clarify the nature of these traits via an exploratory approach to test construction. This measure, the Psychopathic Personality inventory (PPI), was developed by writing items to assess a large number of personality domains relevant to psychopathy and performing successive item-level factor analyses and revisions on three undergraduate samples. The PPI total score and its eight subscales were found to possess satisfactory internal consistency and test-retest reliability. In four studies with undergraduates, the PPI and its subscales exhibited a promising pattern of convergent and discriminant validity with self-report, psychiatric interview, observer rating, and family history data. In addition, the PPI total score demonstrated incremental validity relative to several commonly used self-report psychopathy-related measures. Future construct validational studies, unresolved conceptual issues regarding the assessment of psychopathy, and potential research uses of the PPI are outlined.     

Development and Preliminary Validation of a New Measure to Assess Shame: The Shame Inventory

Research on the emotion of shame has increased significantly in recent years. However, there remains a need for more psychometrically sound measures of shame, including measures of shame in response to specific, idiographic experiences. The Shame Inventory was developed in order to assess both global feelings of shame as well as shame in response to specific life events or personal characteristics. Two studies were conducted to determine the preliminary psychometric properties of the Shame Inventory. Across both studies, results indicate that the inventory has high internal consistency, test-retest reliability, construct validity, and predictive validity. The Shame Inventory holds promise as a new measure designed to assess both global feelings of shame as well as specific shame-eliciting cues.     

Gender and Wellness: A Multidimensional Systems Model for Counseling

An expanded view of health is advocated for assessment and treatment of individual clients in helping them achieve and maintain their maximum potential for high-level wellness. In addition, moderating variables, such as culture, age, and gender differences, have an impact on every dimension of health and wellness. In this article a multidimensional systems model for wellness is described, and gender differences along those dimensions are reviewed. Application of the model and implications for counseling are discussed. Finally, two illustrative case examples, one man and one woman, are described.

The Physical Appearance Perfectionism Scale: Development and Preliminary Validation

Eight studies with data from 2316 students are presented describing the development and preliminary validation of the Physical Appearance Perfectionism Scale (PAPS), a brief measure with two subscales: Worry About Imperfection and Hope For Perfection. Results from exploratory and confirmatory factor analyses confirmed the measure’s two-dimensional structure. Moreover, correlation analyses provided first evidence for the two subscales’ differential validity: Worry About Imperfection showed negative correlations with positive self-perceptions of one’s appearance (e.g., appearance self-esteem) and positive correlations with maladaptive concerns aspects of perfectionism, physical appearance concerns (e.g., body image disturbances), and body weight control whereas Hope For Perfection showed positive correlations with positive striving aspects of perfectionism, positive self-perceptions, and impression management. In addition, all PAPS scores showed high reliability (Cronbach’s alpha) and temporal stability (test-retest). Overall the findings suggest that the PAPS is a reliable and valid instrument to assess positive and negative aspects of physical appearance perfectionism.     

Assessing Interpersonal Aspects of Schizoid Personality Disorder: Preliminary Validation Studies

In 2 studies, we examined the reliability and validity of an interpersonal measure of schizoid personality disorder (SZPD) based on nonverbal behaviors and interpersonal interactions occurring during interviews. A total of 556 male jail inmates in the United States participated in Study 1; 175 mentally disordered offenders in maximum security hospitals in the United Kingdom participated in Study 2. Across both samples, scores on the Interpersonal Measure of Schizoid Personality Disorder (IM–SZ) exhibited adequate reliability and patterns of correlations with other measures consistent with expectations. The scale displayed patterns of relatively specific correlations with interview and self-report measures of SZPD. In addition, the IM–SZ correlated in an expected manner with features of psychopathy and antisocial personality and with independent ratings of interpersonal behavior. We address implications for assessment of personality disorder.
