The Prospective and Retrospective Memory Questionnaire (PRMQ): Normative data and latent structure in a large non-clinical sample

The Prospective and Retrospective Memory Questionnaire (PRMQ; Smith, Della Sala, Logie, & Maylor, 2000) was developed to provide a self-report measure of prospective and retrospective memory slips in everyday life. It consists of sixteen items, eight asking about prospective memory failures, and eight concerning retrospective failures. The PRMQ was administered to a sample of the general adult population (N = 551) ranging in age between 17 and 94. Ten competing models of the latent structure of the PRMQ were derived from theoretical and empirical sources and were tested using confirmatory factor analysis. The model with the best fit had a tripartite structure and consisted of a general memory factor (all items loaded on this factor) plus orthogonal specific factors of prospective and retrospective memory. The reliabilities (internal consistency) of the Total scale and the Prospective and Retrospective scales were acceptable: Cronbach's alpha was 0.89, 0.84, and 0.80, respectively. Age and gender did not influence PRMQ scores, thereby simplifying the presentation and interpretation of normative data. To ease interpretation of scores on the PRMQ, tables are presented for conversion of raw scores on the Total scale and Prospective and Retrospective scales to T scores (confidence limits on scores are also provided). In addition, tables are provided to allow users to assess the reliability and abnormality of differences between an individual's scores on the Prospective and Retrospective scales.

Brazelton Neonatal Behavioral Assessment Scale: A psychometric study in a Portuguese sample

BackgroundThe Neonatal Behavioral Assessment Scale (NBAS, Brazelton &; Nugent, 1995) is an instrument conceived to observe the neonatal neurobehavior. Data analysis is usually performed by organizing items into groups. The most widely used data reduction for the NBAS was developed by Lester, Als, and Brazelton (1982).ObjectiveExamine the psychometric properties of the NBAS items in a sample of 213 Portuguese infants.MethodThe NBAS was performed in the first week of infant life (3 days ± 2) and in the seventh week of life (52 days ± 5).ResultsPrincipal component analyses yielded a solution of four components explaining 55.13% of total variance. Construct validity was supported by better neurobehavioral performance of 7-week-old infants compared with 1-week-old infants.ConclusionChanges in the NBAS structure for the Portuguese sample are suggested compared to Lester factors in order to reach better internal consistency of the scale.     

Personal disturbance scale: factor structure confirmed in a large nonclinical sample

The two-component structure of anxiety and depression items of the short form Personal Disturbance Scale, reported in an earlier clinical study of 480 adult psychiatric patients, was substantially replicated in a large nonclinical sample of 758 adults.     

Translation and Standardization of the Sex-Role Egalitarianism Scale (SRES-B) on a German Sample

This study presents a German-language version of the sex-role egalitarianism scale (SRES-B) L. A. King, & D. W. King, 1993]. The SRES measures a person’s attitude toward egalitarianism between women and men. It has been normed on different populations, but there was no German version of the scale. The purpose of the present study was to translate and assess the psychometric properties of the SRES-B on a German population (n=379). As expected, sex, age, and educational level affected the scores of individuals on the scale. The results of factor analyses of the domain scores and correlations of subscales demonstrate a unidimensionality of the construct. The quality of the psychometric properties of items and scale was satisfactory. Implications and future directions for research are discussed.The research was conducted as part of the author’s master thesis, while at the University of Osnabrueck, Germany.     

The NEO Five-Factor Inventory: latent structure and relationships with dimensions of anxiety and depressive disorders in a large clinical sample

The present study evaluated the latent structure of the NEO Five-Factor Inventory (NEO FFI) and relations between the five-factor model (FFM) of personality and dimensions of DSM-IV anxiety and depressive disorders (panic disorder, generalized anxiety disorder [GAD], obsessive-compulsive disorder, social phobia [SOC], major depressive disorder [MDD]) in a large sample of outpatients (N = 1,980). Exploratory structural equation modeling (ESEM) was used to show that a five-factor solution provided acceptable model fit, albeit with some poorly functioning items. Neuroticism demonstrated significant positive associations with all but one of the disorder constructs whereas Extraversion was inversely related to SOC and MDD. Conscientiousness was inversely related to MDD but demonstrated a positive relationship with GAD. Results are discussed in regard to potential revisions to the NEO FFI, the evaluation of other NEO instruments using ESEM, and clinical implications of structural paths between FFM domains and specific emotional disorders.     

Religious obsessions and compulsions in a non-clinical sample: the Penn Inventory of Scrupulosity (PIOS)

The present investigation reports on the development and psychometric evaluation of the Penn Inventory of Scrupulosity (PIOS), a 19-item self-report scale measuring religious obsessive-compulsive symptoms. Factor analysis yielded a two factor solution with the first subscale measuring fears about having committed sin, and the second measuring fears concerning punishment from God. Using a sample of college students, the PIOS was shown to be internally consistent and possess good convergent and discriminant validity. Highly devout participants evidenced higher scores on both PIOS subscales, but devout Jews evidenced fewer fears of sin and punishment from God compared to devout Protestants or Catholics. The PIOS has utility both as a research and clinical tool.     

Unique sets of social and mood characteristics differentiate autistic and negative schizotypy traits in a young adult non-clinical sample

While well-established as distinct disorders, new evidence linking autism and schizophrenia has emerged. One line of evidence is the strong correlation identified between the social traits assessed by the Autism Spectrum Quotient (AQ:Social) and the negative traits of schizotypy. To further explore this association, the current study examined whether these sets of traits are convergent or divergent in the degree to which they relate to specific aspects of socio-emotional functioning. Regression analyses conducted on self-report data collected from 284 undergraduate students showed that the social items from the AQ uniquely relate to levels of social anxiety and social skills, while negative schizotypy traits uniquely relate to social anhedonia and depression. Additionally, AQ:Social and negative schizotypy traits were found to share a significant proportion of variance, independent of each of the socio-emotional variables examined. The results thus provide further evidence of shared atypical social function linked to both autistic-like traits and negative schizotypy traits, but importantly also highlight clear differences in the specific socio-emotional profiles associated with these sets of traits.     

The tripartite model and dimensions of anxiety and depression: an examination of structure in a large school sample

This study was designed to build on recent findings that (a) factors of the tripartite model in adults are not uniformly related to all anxiety disorder dimensions as recent research has suggested (T. A. Brown, B. F. Chorpita, & D. H. Barlow, 1998; S. Mineka, D. W. Watson, & L. A. Clark, 1998), and (b) the tripartite model of emotion appears to have increasing support and utility in child samples (e.g., C. J. Lonigan, E. S. Hooe, C. F. David, & J. A. Kistner, 1999). The structural relations were evaluated among tripartite factors and dimensions representing selected anxiety disorders and depression in a large multiethnic school sample of children and adolescents. General aspects of the tripartite model were supported. For example, Negative Affect was positively related with all anxiety and depression scales, and Positive Affect was negatively correlated with the depression scale. Consistent with previous observations in adult samples, Physiological Hyperarousal was positively related with Panic only, and was not significantly positively correlated with other anxiety syndromes. The structure of the best fitting model appeared robust across different grade levels and gender. In follow-up analyses, several interactions of grade level with structural parameters emerged, such that the relation of some of the tripartite factors with anxiety and depression were noted to increase or decrease across grade level.     

The factor structure of the Personality Assessment Inventory-Borderline Features (PAI-BOR) Scale in a nonclinical sample.

We evaluated the fit of Morey's (1991) proposed 4-factor structure on Personality Assessment Inventory-Borderline Features Scale (PAI-BOR; Morey, 1991) items in a sample of approximately 5,000 nonclinical participants. The proposed model did not fit the data well. Results from a series of exploratory and confirmatory factor analyses suggested that a 6-factor model provided the best fit to the PAI-BOR item covariances.     

Evaluating the latent structure of the MMPI-2 F(p) scale in a forensic sample: a taxometric analysis

P. A. Arbisi and Y. S. Ben-Porath (1995) originally proposed that the Infrequency Psychopathology scale, F(p), be used as the final step in an algorithm to determine the validity of a Minnesota Multiphasic Personality Inventory-2 (MMPI-2) protocol. The current study used taxometric procedures to determine the latent structure of F(p) among examinees with profiles that would necessitate the interpretation of F(p) when using Arbisi and Ben-Porath's proposed algorithm. Participants included a subsample of 289 consecutively referred pretrial forensic examinees adjudicated incompetent to stand trial with high Infrequency (F) scale scores, thereby providing a sample that would be expected to have a high base rate of persons with bona fide psychopathology and persons with incentive to overreport psychopathology. Using MAMBAC and MAXEIG, F(p) produced a taxonic latent structure within the subgroup of examinees who obtained raw scores on F of greater than 17. These results support Arbisi and Ben-Porath's original proposal to use F(p) to identify a distinct subgroup of overreported MMPI-2 protocols within forensic psychiatric examinees with high elevations on F. Implications and suggestions for future research are provided.     

The Stroop color-word test: influence of age, sex, and education; and normative data for a large sample across the adult age range

The Stroop Color-Word Test was administered to 1,856 cognitively screened, healthy Dutch speaking participants aged 24 to 81 years. The effects of age, gender, and education on Stroop test performance were investigated to adequately stratify the normative data. The results showed that especially the speed-dependent Stroop scores (time to complete a subtest), rather than the accuracy measures (the errors made per Stroop sub-task), were profoundly affected by the demographic variables. In addition to the main effects of the demographic variables, an Age Low Level of Education interaction was found for the Error III and the Stroop Interference scores. This suggests that executive function, as measured by the Stroop test, declines with age and that the decline is more pronounced in people with a low level of education. This is consistent with the reserve hypothesis of brain aging (i.e., that education generates reserve capacity against the damaging effects of aging on brain functions). Normative Stroop data were established using both a regression-based and traditional approach, and the appropriateness of both methods for generating normative data is discussed.     

The Perceived Stress Scale: Factor structure and relation to depression symptoms in a psychiatric sample

The present study sought to examine the factor structure and psychometric properties of the Perceived Stress Scale (PSS) when administered to psychiatric patients. We also examined predictive validity of the PSS by assessing the association between the Perceived Stress Scale and the Beck Depression Inventory. A heterogeneous sample of 96 psychiatric patients (48 men, 48 women) completed the Perceived Stress Scale (PSS) and the Beck Depression Inventory. Factor analysis of the PSS established that the scale consisted of two factors. The first factor was comprised primarily of items reflecting adaptational symptoms. In contrast, the second factor consisted of items reflecting coping ability. Both factors had an adequate degree of internal consistency. Finally, a series of regression analyses predicting depression found that both factors accounted for unique variance in depression scores in women, but only the first factor accounted for unique variance in men. It is concluded that the PSS is a multidimensional and internally consistent measure of perceived stress.This research was supported by Grant 410-91-1690 from the social sciences and Humanities Research Council of Canada as well as by grants from the Research and Program Evaluation Committee Brockville Psychiatric Hospital.     

Career adaptability in Lithuania: A test of psychometric properties and a theoretical model

The Career Adapt-Abilities Scale-Lithuanian Form consists of four six-item subscales measuring concern, control, curiosity, and confidence. These are thought to be the main dimensions of career adaptability reflecting individual psychosocial resources to cope with occupational transitions, developmental tasks, and work traumas. Two studies were administered in a sample (N  =  767) of Lithuanian high school students. The results showed factor structure to be identical to that of the CAAS-International Form. Moreover, good to excellent scale internal consistency coefficients were obtained. With a slight exception, MIMIC model analysis revealed no major effects of demographic variables upon the CAAS factor or factor indicator scores. Concurrent validity analysis showed career adaptability, as measured by the CAAS-Lithuanian Form, to be significantly related to career aspirations, to the frequency of career exploration behaviors and to career decidedness. Finally, as hypothesized by the career construction model of adaptation, career exploration behaviors mediated the link between career adaptability and decidedness.     

Clarifying boundaries of binge eating disorder and psychiatric comorbidity: a latent structure analysis

Binge eating disorder (BED) presents with substantial psychiatric comorbidity. This latent structure analysis sought to delineate boundaries of BED given its comorbidity with affective and anxiety disorders. A population-based sample of 151 women with BED, 102 women with affective or anxiety disorders, and 259 women without psychiatric disorders was assessed with clinical interviews and self-report-questionnaires. Taxometric analyses were conducted using DSM-IV criteria of BED and of affective and anxiety disorders. The results showed a taxonic structure of BED and of affective and anxiety disorders. Both taxa co-occurred at an above-chance level, but also presented independently with twice-as-large probabilities. Within the BED taxon, diagnostic co-occurrence indicated greater general psychopathology, lower social adaptation, and greater premorbid exposure to parental mood and substance disorder, but not greater eating disorder psychopathology. Eating disorder psychopathology discriminated individuals in the BED taxon from individuals in the affective and anxiety disorders taxon. Diagnostic criteria of BED were more indicative of the BED taxon than were criteria of affective and anxiety disorders. The results show that at the latent level, BED was co-occurring with, yet distinct from, affective and anxiety disorders and was not characterized by an underlying affective or anxiety disorder.     

The Depression Anxiety and Stress Scales: Reference data from a large psychiatric outpatient sample

The published norms for the Depression Anxiety and Stress Scale (DASS) give results for clinical populations that largely fall in the severe to very severe categories. As a result, within this population, the ability to compare the comparative contributions of the underlying emotional components is reduced. The present study presents results from a large general psychiatric outpatient population and provides percentile norms with confidence intervals for both the original DASS and the shorter 21‐item form. It is noted that both forms have high validity but that the correlations between scales are higher than those reported in non‐clinical populations. There was little variation between sexes but some variation of results with age with both younger and older cohorts having lower scores except for the Stress scale where there were higher scores in the older group. There is some evidence of a ceiling effect in the Depression and Stress scales. It was noted that nearly a quarter of patient scores fell within the originally defined normal range suggesting that the DASS would not be a particularly sensitive instrument in its previously reported use as a screening instrument for psychiatric illness.     

The Toronto Alexithymia Scale (TAS-20): A measure of general psychological distress

The Toronto Alexithymia Scale (Bagby, R. M., Parker, J. D. A., & Taylor, G. J. (1994). The twenty-item Toronto Alexithymia Scale-I. Item selection and cross-validation of the factor structure. Journal of Psychosomatic Research, 38, 23–32.) is the most commonly used measure of Alexithymia (= difficulties identifying and describing one’s own feelings). Sixty-three persons (34 psychiatric inpatients, 29 healthy controls) first filled in the TAS-20 and were then interviewed about their interpersonal relationships. Two raters coded the emotional experiences that the participants reported during these interviews. Contrary to expectations, participants with higher TAS-20 scores reported more emotions (particularly negative ones), and more different emotions, questioning the validity of the TAS-20 as a measure of Alexithymia. Based on correlation patterns and a joint factor analysis with two well-established measures of psychopathology, it is concluded that the TAS-20 assesses a general psychological distress factor.     

The Sociocultural Attitudes Toward Appearance Questionnaire (SATAQ-3): reliability and normative comparisons of eating disordered patients

The Sociocultural Attitudes Toward Appearance Questionnaire-3 (SATAQ-3) is a measure of one’s endorsement of societal appearance ideals. The measure has received extensive evaluation in normative samples, but only minimal evaluation in clinical groups. In this study, 440 patients with eating disorders completed the SATAQ-3. Internal consistencies were excellent for the four SATAQ-3 subscales. Groups did not differ by diagnosis on the Information subscale, however, individuals with bulimia nervosa scored higher than individuals with both subtypes of anorexia nervosa (restricting and binge eating/purging) on levels of Internalization-General and Internalization-Athlete. The findings provide informative normative data, along with preliminary results indicative of the potentially greater role of media messages and images in the formation and/or maintenance of bulimia nervosa than anorexia nervosa.     

An expanded childhood anxiety sensitivity index: its factor structure, reliability, and validity in a non-clinical adolescent sample

Anxiety sensitivity refers to the fear of anxiety-related bodily sensations that are interpreted as having potentially harmful somatic, psychological, or social consequences. The current study examined the factor analytic structure of anxiety sensitivity in a large sample of normal adolescents (N=518) using the revised childhood anxiety sensitivity index (CASI-R). Confirmatory factor analysis indicated that anxiety sensitivity as measured by the CASI-R can best be conceptualised as a hierarchical construct with four lower-order factors loading on a single higher-order factor. The lower-order factors were 'fear of cardiovascular symptoms', 'fear of publicly observable anxiety reactions', 'fear of cognitive dyscontrol', and 'fear of respiratory symptoms'. An additional aim of the present study was to investigate the psychometric properties of the CASI-R. Results showed the CASI-R to be a reliable scale in terms of internal consistency. Furthermore, CASI-R scores were substantially related to levels of anxiety sensitivity as measured by the original index, trait anxiety, symptoms of anxiety disorders, in particular 'panic disorder and agoraphobia', and depression. Finally, some evidence was found for the validity of the CASI-R factor scores. That is, all factors convincingly loaded on symptoms of 'panic disorder and agoraphobia', whereas the factor 'fear of publicly observable anxiety reactions' was also strongly associated with symptoms of 'social phobia'.     

The Work Environment Scale and the Ward Atmosphere Scale (short forms): psychometric data

Alpha coefficients of internal consistency for the Short Forms of the Work Environment Scale and Ward Atmosphere Scale, their major dimensions and their subscales are presented. Although some exceptions were noted, the indices reported here attest to the adequate reliability of the short forms of the two scales, which was previously documented for the unabridged forms. The few exceptions are hypothesized to be attributable to either sampling error or the fact that each factor is comprised of only 4 items. The need for further reliability testing of these short forms is emphasized.
