Assessing psychological inflexibility: the psychometric properties of the Avoidance and Fusion Questionnaire for Youth in two adult samples

The current study examined whether the Avoidance and Fusion Questionnaire for Youth (AFQ-Y; L. A. Greco, W. Lambert, & R. A. Baer, 2008), a self-report measure of psychological inflexibility for children and adolescents, might be useful for measuring psychological inflexibility for adults. The psychometric properties of the AFQ-Y were examined using data from a college student sample (N = 387) and a clinical sample of patients with anxiety disorders (N = 115). The AFQ-Y, but not the Acceptance and Action Questionnaire-II (AAQ-II; F. W. Bond et al., in press), demonstrated a reading level at or below the recommended 5th or 6th grade reading level. The AFQ-Y also demonstrated adequate reliability (internal consistency), factorial validity, convergent and discriminant validity, and concurrent validity predicting psychological symptoms. Moreover, the AFQ-Y showed incremental validity over the AAQ-II in predicting several psychological symptom domains. Implications for the assessment of psychological inflexibility are discussed.     

Development and initial validation of the medical fear survey-short version

The present investigation employs item response theory (IRT) to develop an abbreviated medical fear survey (MFS). Application of IRT analyses in study 1 (n = 931) to the original 50-item MFS resulted in a 25-item shortened version. Examination of the location parameters also resulted in a reduction of the Likert-type scaling of the MFS by removing the last response category ("terror"). The five subscales of the original MFS were highly correlated with those of the MFS-short version. The short version also displayed comparable convergent and discriminant validity with the original MFS in relation to measures of fear, disgust, and anxiety. Confirmatory factor analysis in Study 2 revealed that the five-factor structure of the MFS-short form fit the data well in U.S. (n = 283) and Dutch (n = 258) samples. The short form also had comparable convergent and discriminant validity with the original MFS in relation to domains of disgust in both samples. Receiver operating characteristic (ROC) analysis in Study 3 demonstrated that the subscales of the short version were comparable with the original MFS in classifying participants high (n = 40) and low (n = 40) in blood/injection phobia. Last, structural equation modeling in Study 4 (n = 113) revealed that the MFS-short form demonstrated excellent convergent/discriminant validity with strong associations with injection fear and no association with spider fear. These findings suggest that the MFS-short form has considerable strengths, including decreased assessment time, while retaining sound psychometric properties.     

A short form of the Common Beliefs Survey III

Previous studies have shown that the Common Beliefs Survey III (CBS III) is an irrational beliefs inventory with satisfactory psychometric properties. We extended research on the CBS by examining this 54-item inventory for redundant material, and substantially abbreviated it without compormising its reliability or validity. This article describes the development of the new, 19-item short form (CBS19), convenient for clinical use, that preserves the psychometric properties of the original.     

Parenting Behaviors and Childhood Anxiety: A Psychometric Investigation of the EMBU-C

Parent rearing behaviors, including both behavioral modeling and parent–child interactions, are associated with anxiety in children. Patterns of overprotection or rejecting behavior from parents may lead children to develop behavioral avoidance, lower self-confidence, and higher symptoms of anxiety. Additional research is needed to further elucidate the role that parenting behavior plays in the development of childhood anxiety. Unfortunately, few measures of parenting behavior exist. The EMBU-C is a 40-item child-report measure of these behaviors, but empirical data supporting the psychometric properties of the EMBU-C are limited. The current investigation examined the psychometric properties of the EMBU-C in the context of childhood anxiety. Participants were 213 children with an anxiety disorder and 150 recruited from the community (all aged 8–13 years). Overall, the EMBU-C demonstrated promising psychometrics. In terms of convergent validity, parent rearing behaviors described on the EMBU-C were significantly related to children’s anxiety symptoms, anxiety-related disability, parenting stress, family functioning and children’s externalizing behaviors. Further, the overprotection and anxious-rearing subscales discriminated between clinical and community participants. Finally, parental overprotection significantly predicted increases in child anxiety and anxiety-related disability 1 year later. Thus, the EMBU-C appears to have value as a clinical tool for assessing parental factors that may contribute to anxiety in children. Recommendations for further item development and measure improvement are offered.     

Brief assessment of schizotypy: Developing short forms of the Wisconsin Schizotypy Scales

The Wisconsin Schizotypy Scales—the Perceptual Aberration, Magical Ideation, Physical Anhedonia, and Revised Social Anhedonia Scales—have been used extensively since their development in the 1970s and 1980s. Based on psychometric analyses using item response theory, the present work presents 15-item short forms of each scale. In addition to being briefer, the short forms omit items with high differential item functioning. Based on data from a sample of young adults (n = 1144), the short forms have strong internal consistency, and they mirror effects found for the longer scales. They thus appear to be a good option for researchers interested in the brief assessment of schizotypic traits. The items are listed in an Appendix A.     

Measuring the phenomenology of autobiographical memory: A short form of the Memory Experiences Questionnaire

The Memory Experiences Questionnaire (MEQ) is a theoretically driven and empirically validated 63-item self-report scale designed to measure 10 phenomenological qualities of autobiographical memories: Vividness, Coherence, Accessibility, Time Perspective, Sensory Details, Visual Perspective, Emotional Intensity, Sharing, Distancing and Valence. To develop a short form of the MEQ to use when time is limited, participants from two samples (N = 719; N = 352) retrieved autobiographical memories, rated the phenomenological experience of each memory and completed several scales measuring psychological distress. For each MEQ dimension, the number of items was reduced by one-half based on item content and item-total correlations. Each short-form scale had acceptable internal consistency (median alpha = .79), and, similar to the long-form version of the scales, the new short scales correlated with psychological distress in theoretically meaningful ways. The new short form of the MEQ has similar psychometric proprieties as the original long form and can be used when time is limited.     

Development and validation of a modified version of the Peritraumatic Dissociative Experiences Questionnaire

This article reports results from 3 studies conducted to develop and validate a modified version of the self-administered form of the Peritraumatic Dissociative Experiences Questionnaire (PDEQ; C. R. Marmar, D. S. Weiss, & T. J. Metzler, 1997). The objective was to develop an instrument suitable for use with persons from diverse ethnic and socioeconomic backgrounds. In Study 1, the original PDEQ was administered to a small sample (N = 15) recruited from among men admitted to the hospital for physical injuries stemming from exposure to community violence. Results led to modifications aimed at improving the utility of the instrument. In Study 2, the modified PDEQ was subjected to structural equation modeling and item response theory analyses to assess its psychometric properties in a larger, primarily male, sample of community violence survivors (N = 284). In Study 3, the reliability and validity of the modified instrument were further assessed in a sample of female survivors of sexual assault (N = 90). Results attest to the psychometric properties as well as the reliability and validity of the modified 8-item PDEQ.     

Efficiently assessing negative cognition in depression: an item response theory analysis of the Dysfunctional Attitude Scale

Despite a central role for dysfunctional attitudes in cognitive theories of depression and the widespread use of the Dysfunctional Attitude Scale, form A (DAS-A; A. Weissman, 1979), the psychometric development of the DAS-A has been relatively limited. The authors used nonparametric item response theory methods to examine the DAS-A items and develop a briefer version of the scale. Using DAS-A data obtained from depressed participants enrolled in 2 large depression treatment studies (N=367), the authors developed a 9-item DAS form (DAS-SF1). In addition, because 2 versions of the DAS are needed for certain study designs, they also developed a 2nd short version (DAS-SF2). These short forms were highly correlated with the original 40-item DAS-A (rs ranged from .91 to .93), exhibited change similar to that of the DAS-A over the course of treatment, were moderately correlated with related self-report assessments, predicted concurrent depression severity, and predicted change in depression from before to after treatment. Taken together, the authors believe the DAS-SF1 and DAS-SF2 provide an efficient and accurate assessment of dysfunctional attitudes among depressed individuals.     

Dyscontrol Experiences Questionnaire: Development, Reliability and Validity

This paper describes development of a retrospective measure of childhood exposure to parental dyscontrol related to specific conditions such as a parent's drinking, anger, or other negative emotional states (e.g., stress, anxiety, depression). A 45-item questionnaire, the Dyscontrol Experiences Questionnaire (DEQ), was designed to assess individuals' childhood experiences with parental loss of control. Two student samples (n = 465 and n = 536) completed a battery of self-report measures. Responses were used to examine the psychometric properties of the DEQ. Factor analysis revealed three lower-order factors accounting for 54.4% of the variance in DEQ item scores. Cronbach's coefficient alphas indicated acceptable internal consistency. Moderate intercorrelations with two other retrospective measures of childhood experiences suggested construct validity. Moderate intercorrelations with two measures of psychological distress suggested predictive validity. In summary, initial psychometric testing of the DEQ suggests it is a reliable and valid tool for investigating an important developmental antecedent of adult psychological distress.     

Initial development of a brief measure of psychological distress

This paper addresses the preliminary development, construct validity, and psychometric properties of a brief self-report measure of psychological distress. 40 items were originally generated by doctoral level psychologists for use in the preliminary clinical sample. Inpatients from a psychiatric unit (N = 125) completed the items, and a principal-components analysis with a direct oblimin rotation was used to evaluate construct validity. The study indicated a four-factor solution, using the constructs of Depression, Hopelessness, Anxiety, and Anger, with good estimates of reliability. After evaluation of factor structure, item analyses, and reliability estimates, a redacted 19-item scale was identified.     

SA-45: a brief form of the SCL-90

The Symptom Assessment-45 Questionnaire (SA-45) is a 45-item self-report instrument of psychiatric symptomatology derived from the original SCL-90. The SA-45 consists of nine 5-item scales assessing each of the same symptom domains as its parent instrument with no item overlap across domains. This paper provides preliminary validation of the Spanish version of the questionnaire in an undergraduate sample. Exploratory and confirmatory factor analyses supported a 9-factor structure, which corresponds to the nine proposed scales. Normative data, reliability (internal consistency) and validity were also examined, finding support for sound psychometric properties.     

The Loneliness Questionnaire-Short Version: an evaluation of reverse-worded and non-reverse-worded items via item response theory

Although reverse-worded items have often been incorporated in scale construction to minimize the effects of acquiescent reporting biases, some researchers have more recently begun questioning this approach and wondering whether the advantages associated with incorporating reverse-worded items is worth the complexities that they bring to measures (e.g., Brown, 2003 ; Marsh, 1996 ). In this study, we used item response theory (IRT) to determine whether there is statistical justification to eliminate the reverse-worded items (e.g., "I have lots of friends") from the Loneliness Questionnaire (LQ; Asher, Hymel, & Renshaw, 1984) and retain only the non-reverse-worded items (e.g., "I'm lonely") to inform the provision of a shortened LQ version. Using a large sample of children (Grades 2-7; n = 6,784) and adolescents (Grades 8-12; n = 4,941), we examined the psychometric properties of the 24-item LQ and found support for retaining the 9 non-reverse-worded LQ items to make up a shortened measure of loneliness in youth. We found that the non-reverse-worded items were associated with superior psychometric properties relative to the reverse-worded items with respect to reliability and IRT parameters (e.g., discrimination and item information). A 3-point Likert-type scale was also found to be more suitable for measuring loneliness across both children and adolescents compared to the original 5-point scale. The relative contributions of reverse-worded and non-reverse-worded items in scale development for youth instruments are also discussed.     

A comparison of the psychometric properties of the psychopathic personality inventory full-length and short-form versions

The Psychopathic Personality Inventory (PPI) has shown promising construct validity as a measure of psychopathy. Because of its relative efficiency, a short-form version of the PPI (PPI-SF) was developed and has proven useful in many psychopathy studies. The validity of the PPI-SF, however, has not been thoroughly examined, and no studies have directly compared the validity of the short form with that of the full-length version. The current study was designed to compare the psychometric properties of both PPI versions, with an emphasis on convergent and discriminant validity in predicting external criteria conceptually relevant to psychopathy. We used both prison (n = 558) and college samples (n = 322) for this investigation. PPI scale scores were more reliable and more strongly correlated with the conceptually relevant criterion measures compared with the PPI-SF, particularly in the prison sample. There were no differences in relative discriminant validity. Thus, overall, the PPI full-length version showed more evidence of construct validity than did the short form, and the consequences of this psychometric difference should be considered when evaluating the clinical utility of each measure.

Assessing Emotional Reactivity: Psychometric Properties of the Perth Emotional Reactivity Scale and the Development of a Short Form

The Perth Emotional Reactivity Scale (PERS) is a 30-item self-report measure of trait levels of emotional reactivity. In this article, we examine the psychometric properties of the PERS subscale and composite scores in an adult community sample (N = 428), and develop an 18-item short form of the measure (PERS–S). The PERS and PERS–S are designed to assess the typical ease of activation, intensity, and duration of one's emotional responses, and do so for positive and negative emotions separately. Our confirmatory factor analyses supported that the PERS and PERS–S both had the same theoretically congruent factor structure, and that all subscale and composite scores displayed high internal consistency reliability. Correlations with scores from established measures of psychopathology and emotion regulation also supported the validity of PERS and PERS–S scores. Our data therefore suggest that the PERS–S subscale and composite scores retain the psychometric strengths of their longer PERS counterparts. We conclude that both forms of the measure have good utility. Clinical and research applications are discussed.     

Psychometric Characteristics of the German Values in Action Inventory of Strengths 120-Item Short Form

The original Values in Action Inventory of Strengths (VIA-IS) is an international 240 item validated self-report questionnaire measuring character strengths. A validated and reliable English 120-item short form (VIA-120) is available. However, there is limited information about the psychometric properties of the German VIA-120. This article addresses this gap and reports the reliability, validity and comparability of the German VIA-120 with the German VIA-240 version. Two independent samples were recruited: a general population sample (N = 1073, Sample 1) and a sample consisting of medical students and physicians (N = 685, Sample 2). Internal consistency of the VIA-120-scales ranged from α = .58 (modesty) to α = .87 (spirituality) in Sample 1 and α = .63 (honesty) to α = .90 (spirituality) in Sample 2. Intercorrelations between the scales of the 120-item version and the original 240-Items version (Sample 1) ranged from r = .52 (hope) to r = .89 (prudence). Criterion validity with the Satisfaction with Life Scale (SWLS) and the Brief Inventory of Thriving (BIT) was demonstrated. The comparison of the factor structure between the original and the short form showed a good convergence (Tucker’s Phi .93–.99 Sample 1, .95–.98 Sample 2). Overall, the German VIA-120 was reliable, showed good convergence with the German VIA-240 and thus presents a similar level of validity for the assessment of character strengths. This study provides the first indication that the VIA 120 short form is comparable regarding the validity and reliability of the original VIA 240-item version indicating its potential to be used in large scale research studies.

     

Development and validation of a brief mental health screening instrument for newly incarcerated adults

The authors report the development and initial psychometric evaluation of gender-specific brief screening instruments to identify undetected psychiatric impairment on incarceration. Women and men completed the Correctional Mental Health Screen (CMHS), a 56-item screen derived from validated measures. Representative subsamples completed structured diagnostic interviews within 5 days. An 8-item screen for women and a 12-item screen for men identified inmates with current Axis I psychiatric disorders with 83% to 100% accuracy on the basis of cut points chosen to maximize negative predictive power. The CMHS showed evidence of incremental predictive utility compared with two previously validated correctional mental health screening measures with White and Black men and White women. Incremental validity was not supported with Black women, for whom the CMHS performed well in identifying true cases but not in ruling out noncases. Analyses of internal consistency, interrater, and retest reliability and convergent, discriminant, and criterion validity supported the psychometric status of the CMHS.     

Measuring the validity and psychometric properties of a short form of the Hypomanic Personality Scale

The Hypomanic Personality Scale (HPS) is used to investigate hypomanic traits and risk for bipolar spectrum disorders; however, the length of the HPS (48 items) may be prohibitive for clinical research and screening purposes. Meads and Bentall (2008) developed a promising 20-item version of the HPS; however, the psychometric properties and validity of the short form have not been thoroughly examined. The present study investigated the construct validity and psychometric properties of the short HPS. A sample of 2713 non-clinically ascertained young adults was used to assess psychometric properties of the short form relative to the original scale. Two non-overlapping subsamples (n = 522; n = 145) were used to investigate the validity of the short HPS using personality and temperament questionnaires and clinical interviews of bipolar psychopathology and diagnoses. The short and original HPS generally had comparable correlations with measures of temperament, personality, impulsivity, borderline personality, grandiosity, psychosocial functioning, and alcohol use, and comparably predicted DSM bipolar and bipolar spectrum diagnoses. Overall, the short HPS was found to be both reliable and valid. However, the short HPS tended to be more strongly correlated with pathological components of hypomanic personality and less strongly correlated with exuberant and potentially adaptive aspects of the construct.
