Psychosocial functioning in the context of diagnosis: Assessment and theoretical issues.

Psychosocial functioning is an important focus of attention in the revision of the Diagnostic and Statistical Manual of Mental Disorders. Researchers and clinicians are converging upon the opinion that psychometrically strong, comprehensive assessment of individuals' functioning is needed to characterize disorder fully. Also shared is the realization that existing theory and research in this domain have critical shortcomings. The authors urge that the field reexamine the empirical evidence and address theoretical issues to guide future development of the construct and its measurement. The authors first discuss several theoretical issues relevant to the conceptualization and assessment of functioning: (a) definitions of functioning, (b) the role of functioning in defining disorder, and (c) understanding functioning within environmental contexts. The authors then present data regarding empirical domains of psychosocial functioning and their interrelations. Self-reported data on multiple domains of psychosocial functioning were collected from 429 participants. Factor-analytic results (promax rotation) suggest a 4-factor structure of psychosocial functioning: Well-Being, Basic Functioning, Self-Mastery, and Interpersonal and Social Relationships. Finally, the authors propose an integration of theory and empirical findings, which they believe will better incorporate psychosocial functioning into future diagnostic systems.

A psychometric evaluation of the DSM-IV borderline personality disorder criteria: age and sex moderation of criterion functioning

Despite its importance as a paradigmatic personality disorder, little is known about the measurement invariance of the DSM-IV borderline personality disorder (BPD) criteria; that is, whether the criteria assess the disorder equivalently across different groups. BPD criteria were evaluated at interview in 2794 young adult Norwegian twins. Analyses, based on item-response modeling, were conducted to test for differential age and sex moderation of the individual BPD criteria characteristics given factor-level covariate effects. Confirmatory factor analytic results supported a unidimensional structure for the nine BPD criteria. Compared to males, females had a higher BPD factor mean, larger factor variance and there was a significant age by sex interaction on the factor mean. Strong differential sex and age by sex interaction effects were found for the 'impulsivity' criterion factor loading and threshold. Impulsivity related to the BPD factor poorly in young females but improved significantly in older females. Males reported more impulsivity compared to females and this difference increased with age. The 'affective instability' threshold was also moderated, with males reporting less than expected. The results suggest the DSM-IV BPD 'impulsivity' and 'affective instability' criteria function differentially with respect to age and sex, with impulsivity being especially problematic. If verified, these findings have important implications for the interpretation of prior research with these criteria. These non-invariant age and sex effects may be identifying criteria-level expression features relevant to BPD nosology and etiology. Criterion functioning assessed using modern psychometric methods should be considered in the development of DSM-V.

Ideological Consistency and Attitudinal Conf lict

According to attitudinal theorists, justices on the U.S. Supreme Court decide cases largely on political preferences that fall within one dimension of ideology. The focus of this study is to test whether a unidimensional ideological model explains the voting behavior of Canadian Supreme Court justices (1992—1997). The factor-analytic results in three areas of law, two of which have never been examined in this way in Canada, provide substantial evidence of ideological voting. Yet unlike the U.S. justices of the Rehnquist court, Canadian justices exhibit a much higher degree of ideological complexity. These findings call into question the widely held assumption of unidimensional decision making that is in vogue in the U.S. literature today, and they suggest that attitudinal theorists and comparative scholars must be cognizant that multiple dimensions of attitudinal voting might occur in high courts that are not as ideologically polarized as the U.S. Supreme Court.

Factor Structure and Psychometric Properties of the Multidimensional Anxiety Scale for Children in an African American Adolescent Sample

The current study examined the psychometric properties and factor structure of the Multidimensional Anxiety Scale for Children (MASC) among a community sample of 118 African American students (58 females; ages 14-19 years; mean age = 15.79) in an urban, parochial high school. Adolescents completed the MASC and several other self-report measures of anxiety, perceived competence, and symptoms of ADHD. The original MASC total and subscale mean scores were comparable to data reported in previous studies utilizing community samples of youth, though measures of internal consistency were lower. Factor analytic results supported a three factor solution (i.e., social anxiety, physical symptoms, harm avoidance) which accounted for 23.84% of the variance. While there was overlap in the underlying structure of anxiety between the original MASC publication and the current sample, items reflecting separation anxiety did not emerge as a separate factor. As expected, the MASC total score was positively correlated with measures of anxiety and perceived competence but unrelated to measures of hyperactivity. This study represents an important first step toward establishing more comprehensive age, race, and gender norms for the MASC.

Tableplot

In the debate over null hypothesis significance testing, Paul Meehl strongly advocated appraising theories through the generation and evaluation of precise predictions (e.g., Meehl, 1978 ). The study of personality structure through the five-factor model (FFM; McCrae & John, 1992 ) is an important area of research where one encounters many precise predictions. Extant methods of assessing such predictions, however, do not allow researchers to examine the outcome of the predictions in great detail. That is, it may be difficult to determine how estimates fail to match predicted values. As Meehl argued, one must examine how a theory fails to predict in order to refine and improve the theory. To promote better theory appraisal in FFM research, we present a powerful new tool, called a tableplot ( Kwan, 2008a ), that can summarize and clarify factor analytic results. Specifically, we illustrate how the tableplot enables detailed appraisal of precise predictions in the FFM.

Social connectedness, extraversion, and subjective well-being: Testing a mediation model

This investigation examined social connectedness as distinct from extraversion and as a mediation variable in the relationship between extraversion and subjective well-being. A college student sample ( N = 295) and a sample of individuals who identify as lesbian, gay, and bisexual (LGB; N = 148) completed measures of extraversion, social connectedness, life satisfaction, and positive and negative affect. Factor analytic results suggest social connectedness is a unique construct from extraversion. Moreover, the relationship between extraversion and well-being was mediated by social connectedness.

Perceived Stigma and Barriers to Care for Psychological Treatment: Implications for Reactions to Stressors in Different Contexts

Two studies examined how perceiving a stigma and barriers to care for psychological treatment moderate the relationships between stressors and psychological symptoms. One study utilized a sample of college students and the other a sample of U.S. Army soldiers. Factor analytic results from the two samples supported stigma and barriers to care being separate constructs. In the student sample, perceived stigma interacted with subjective stress to predict depression, such that the relationship between stress and depression was stronger when perceived stigma was high. In the military sample, barriers to care interacted with work overload to predict depression, such that the relationship between overload and depression was stronger when perceived barriers to care were high. Results reveal the importance of examining both stigma and barriers to care as moderators of the stressor–strain relationship, and reinforce the need to develop interventions to address stigma and remove barriers to care.

Measuring Small-Group Environments

This concurrent validity study of Salter Environmental Type Assessment scores was conducted with the Group Environment Scale. A principal components factor analysis with varimax rotation of 191 college students' responses suggested two factors that accounted for 51% of the variance. The factor-analytic results and concurrent validity coefficients were consistent with previous research with both assessments and theoretical assumptions behind the two approaches to measuring group climate. Implications for the assessment of groups are discussed.

Psychological wellness constructs: relationships and group differences

The objective of the study was to examine the relationships between several constructs that were hypothesised to be components underlying psychological wellness and to establish whether there were differences between managerial and non-managerial groups or between Black and White groups in respect of the wellness variables. The Personal Orientation Inventory (POI), Locus of Control Inventory (LOC), Sense of Coherence Scale (SOC), and the Bar-On EQ-I were administered to a random sample of 200 employees of a financial services company. Statistically significant differences were found between the groups on several of the wellness variables with the manager and White groups obtaining higher scores on these variables than their comparison groups. However, in respect of External Locus of Control, the non-manager and Black groups obtained the higher scores. Factor analytic results demonstrated that the wellness variables clustered in two correlated factors (r = 0,43) labeled psychological wellness and self-actualisation.

Examining Work Ethic Across Populations

The authors examined the measurement equivalence of the Multidimensional Work Ethic Profile (MWEP) across the diverse cultures of Korea, Mexico, and the United States. Korean- and Spanish-language versions of the MWEP were developed and evaluated relative to the original English version of the measure. Confirmatory factor analytic results indicated measurement invariance across samples drawn from each country. Further analyses indicated potential substantive differences for some of the seven subscales of the MWEP across samples. The implications of these findings and directions for future research are presented.

Development and validation of Patient Reported Impact of Spasticity Measure (PRISM)

Persons with spinal cord injury (SCI) may experience a range of symptoms typically labeled "spasticity." Previous efforts to develop assessment tools that measure spasticity have failed to represent the experiences of persons who live with the condition. The purpose of this multicenter study was to develop an instrument that measures the impact of spasticity on quality of life. Based on 24 semistructured interviews, a developmental form of the Patient Reported Impact of Spasticity Measure (PRISM) was constructed. The developmental PRISM was administered to 180 persons at five sites. Subscales were developed based on factor analytic results. Evidence for the reliability and validity of the scores was evaluated. Seven subscales were developed, including one that measures the positive effects of spasticity. Results of reliability and validity assessments indicate that the PRISM subscale scores effectively measure the impact of spasticity in the population of veterans with SCI.

Taxometric and factor analytic models of anxiety sensitivity: Integrating approaches to latent structural research.

This study represents an effort to better understand the latent structure of anxiety sensitivity (AS), as indexed by the 16-item Anxiety Sensitivity Index (ASI; S. Reiss, R. A. Peterson, M. Gursky, & R. J. McNally, 1986), by using taxometric and factor-analytic approaches in an integrative manner. Taxometric analyses indicated that AS has a taxonic latent class structure (i.e., a dichotomous latent class structure) in a large sample of North American adults (N=2,515). As predicted, confirmatory factor analyses indicated that a multidimensional 3-factor model of AS provided a good fit for the AS complement class (normative or low-risk form) but not the AS taxon class (high-risk form). Exploratory factor analytic results suggested that the AS taxon may demonstrate a unique, unidimensional factor solution, though there are alternative indications that it may be characterized by a 2-factor solution. Findings suggest that the latent structural nature of AS can be conceptualized as a taxonic latent class structure composed of 2 types or forms of AS, each of these forms characterized by its own unique latent continuity and dimensional structure.

Coping Attitudes Scale: Psychometric Properties of a Measure of Positive Attitudes in Depression

The current study investigated the reliability and validity of the Coping Attitudes Scale (CAS), a new measure designed to assess positive cognitions in depression. The CAS is based on cognitive theory and the items reflect the experience of depressed patients during recovery. Psychiatric inpatients (n = 141) meeting criteria for a major depressive disorder and college students (n = 135) completed the CAS and measures of depression and hopelessness. The 23-item CAS demonstrated high internal consistency and retest reliability. Preliminary evidence for validity was observed via strong, negative correlations with measures of depression and hopelessness. Based on difference scores, changes in the CAS were inversely related to changes in depression. However, factor analytic results suggest that the CAS is not merely assessing the opposite of depression. Preliminary findings indicate that the CAS is a reliable, stable scale that measures positive cognitions.

Development and validation of the Stepfamily Life Index

Using schema theory, this study explored the knowledge structures that stepchildren hold about their stepfamilies. Two studies developed a reliable measure of six themes of stepfamily functioning. In Study 1, 251 adult and adolescent stepchildren completed a pilot inventory. Factor-analytic results reduced the pilot inventory from 192 items to 65 items and demonstrated that each dimension could be measured empirically. In Study 2, 586 adult and adolescent stepchildren completed the revised inventory and produced a new, multidimensional measure: The Stepfamily Life Index (SLI). Evidence of internal reliability and discriminant validity for the SLI is offered, and implications are discussed.

Self-consciousness and psychological distress: A study using the Greek SCS

This study examined the psychometric properties and factor structure of the Greek Self-Consciousness Scale (SCS), and investigated the role of self-consciousness (SC), and personality in psychological distress. Factor analytic results partially supported the factor structure of the SCS. Self-consciousness, particularly the Self-reflectiveness aspect of private-SC, was widely implicated in psychological symptomatology. Neuroticism may exacerbate this association, whereas other aspects of personality, such as Openness and Extraversion may buffer the role of SC in distress.

Simple and complex memory spans and their relation to fluid abilities: Evidence from list-length effects

Complex (working memory) span tasks have generally shown larger and more consistent correlations with higher-order cognition than have simple (or short-term memory) span tasks. The relation between verbal complex and simple verbal span tasks to fluid abilities as a function of list-length was examined. The results suggest that the simple span-fluid abilities correlation changes as a function of list-length, but that the complex span-fluid abilities correlation remains constant across list-lengths from lists as short as two items. Furthermore, regression and factor analytic results suggested that the longest simple span list-lengths and all of the complex span list-lengths had both unique and shared variability in predicting fluid abilities, but that estimates of primary memory did not uniquely predict fluid abilities. It is suggested that complex spans, generally, predict higher-order cognition to a greater extent than do simple spans because complex spans require retrieval of items that have been displaced from primary memory due to the processing component of these tasks. Items in simple spans will also be displaced from primary memory but only after primary memory has become overloaded.

Illustrating a mixed-method approach for validating culturally specific constructs

The purpose of this article is to illustrate a mixed-method approach (i.e., combining qualitative and quantitative methods) for advancing the study of construct validation in cross-cultural research. The article offers a detailed illustration of the approach using the responses 612 Sri Lankan adolescents provided to an ethnographic survey. Such surveys offer a connection between the primary methodologies used (i.e., ethnographic and factor analytic approaches) as they are predicated on qualitative inquiry and allow for the application of factor analysis. If the qualitatively derived constructs are comparable to factor analytic results, then triangulation across methods is achieved and a survey can be developed that is sensitive to culturally specific phenomena. The illustration of this approach uses data from an ethnographic survey of self-concept, as defined by Harter (1999) [Harter, S. (1999). The construction of the self: A developmental perspective. New York: The Guilford Press]. The construction of the self: A developmental perspective. New York: The Guilford Press]. The overall finding is that three constructs emerged from the factor analysis and were reconciled with the ethnographic data.

Reliability and Construct Validity of the Pain Distress Inventory

We conducted three studies to evaluate further the reliability and construct validity of a new self-report instrument, the Pain Distress Inventory (PDI; Osman et al., 2003, The Pain Distress Inventory: Development and initial psychometric properties, J. Clin. Psychol. 59: 767-785). In Study I, exploratory and confirmatory factor analytic results confirmed the replicability of the four-factor oblique solution of the PDI in a mixed sample of students and nonstudents. We also found strong evidence for criterion-related validity of scores on this instrument. In Study II, multisample analyses results found further evidence for equivalence of structure of the PDI across African American and Caucasian young adults. Ethnic and gender group differences were obtained on two of the PDI scale scores. Internal consistency reliability estimates on the PDI total and scale scores were good in both Studies I and II. In Study III, additional analyses of internal consistency and known-groups validity established strong support for construct validity of the PDI.

Validating the Beck Depression Inventory-II for Hong Kong Community Adolescents

The primary purpose of this study was to test for the validity of a Chinese version of the Beck Depression Inventory-II (C-BDI-II) for use with Hong Kong community (i.e., nonclinical) adolescents. Based on a randomized triadic split of the data (N = 1460), we conducted exploratory factor analysis on Group1 (n = 486) and confirmatory factor analysis (CFA) within the framework of structural equation modeling on Groups 2 (n = 487) and 3 (n = 487); the second CFA served as a cross-validation of the determined factor structure. Factor analytic results, based on a 4-factor structure that comprised 1 2nd-order general factor of Depression and 3 1st-order factors representing Negative Attitude, Performance Difficulty, and Somatic Elements, replicated those reported previously for Canadian (Byrne & Baron, 1993), Swedish (Byrne, Baron, Larsson, & Melin, 1995), and Bulgarian (Byrne, Baron, & Balev, 1998) nonclinical adolescents. Based on this cross-validated factor structure, findings related to internal consistency reliability, stability over a 6-month time lag, and relations with relevant external criteria provided strong support for the valid use of the C-BDI-II in measuring depressive symptoms for Hong Kong community adolescents.

School children's responses on a semantic differential over a 10-year span.

A semantic differential scale was administered to 208 school children when they were in the second, fourth, sixth, eighth, tenth, and twelfth grades. Their perceptions towards two concepts were measured, Education (going to school) and Work (having a job). Each semantic differential scale had 15 adjective pairs and reflected the three underlying factors of Evaluative, Potency, and Activity. Because the study was conducted for 10 years (ages seven to 18), the changing cognitive developmental stages of the children were expected to influence factor analytic and reliability results. Confirmatory factor analysis, which forced the data into three factors, did not clearly identify the expected three factors, although more items loaded on the three factors with age. An exploratory factor analysis identified a trend across grades from six to four factors over time. Reliability also improved across age groups. Caution should be exercised when using the semantic differential with young children in investigations of abstract concepts.
