Reliability and validity of the borderline personality disorder severity index

The psychometric properties and validity of the Borderline Personality Disorder Severity Index (BPDSI), a semistructured interview assessing the frequency and severity of manifestations of Borderline Personality Disorder (BPD) during a circumscribed period, were investigated in two studies. In study 1, patients with BPD (n = 15), with other personality disorders (PD; n = 18), and without Axis II disorders (but with Axis I disorders; n = 10) assessed with the SCID were interviewed with the BPDSI (1-yr. version). Patients also filled out a number of questionnaires. A second rater judged taped BPDSI interviews. The BPDSI appeared to yield highly reliable (ICC = .93) and internally consistent (Cronbach's alpha = .85) scores. The BPDSI strongly discriminated BPD patients from other patients, and was not related to other Axis II pathology. Concurrent and construct validity was excellent. In study 2, a version of the BPDSI suitable for use in treatment outcome research was investigated (3-month version) in a sample of 64 BPD patients, 23 Cluster C PD patients, and 20 nonpsychiatric controls. Again, reliability coefficients were excellent (ICC = 0.97; Cronbach's alpha = 0.93), and validity indices were good. Clinical norms were also derived. In a sample of 28 BPD patients, the instrument detected improvement during 6 months of psychotherapy.     

Factors associated with eating behavior in pre-adolescents

The goals of this study are the preliminary Spanish adaptation and validation of the following questionnaires: the Children's Eating Attitudes Test (ChEAT), the Lawrence Self-Esteem Questionnaire (LAWSEQ) and the Body Esteem Scale (BES). In addition, we studied bodily self-esteem in pre-adolescent children, and their possible relation to certain eating attitudes and general self-esteem. This study is cross-sectional, analytical and observational. The sample was made up of 457 participants, 55.14% boys and 44.86% girls aged between 8 and 12 (M = 10.14, SD = 1.30). A multivariate analysis of variance (Age x Sex) was carried out with the total scores of LAWSEQ, ChEAT, BES, BIA and BMI. Cronbach's alpha reliability coefficient was .76, .80, and .67 for ChEAT, BES, and LAWSEQ, respectively. The boys presented significantly higher total scores in the ChEAT than the girls. Of the sample, 10.4% (n = 45) scored over the cut-off point of the ChEAT: These subjects presented lower general and bodily self-esteem, a slimmer ideal image and a greater discrepancy between their real self and their social self.     

Psychometric properties of the "Spanish Burnout Inventory" in Chilean professionals working to physical disabled people

While the most commonly employed burnout measure has been the Maslach Burnout Inventory (MBI), researchers have been troubled by some of the psychometric limitations of this instrument. The aim of this study was to analyze the psychometric properties of the "Spanish Burnout Inventory" (SBI). The psychometric properties were analysed with data from a sample of 277 Chilean professionals working to physical disabled people. The psychometric properties of the SBI were examined through the following analyses: confirmatory factor analysis, reliability Cronbach's alpha, and concurrent validity with the MBI. The hypothesized four factor model obtained an adequate data fit for the sample (chi2(164) = 285.32, p < .001, GFI = .96, RMSEA = .052, NNFI .93, CFI = .94). Results confirmed the hypothesis formulated. The Cronbach's alpha coefficient was higher than .70 for the four scales of the instruments. Results supported the concurrent validity with the MBI. As a whole, the results of these study provided evidence on the adequate psychometric properties of the SBI for the study of burnout in the Chilean cultural context.     

The reliability of three visual perception tests used to assess adults

Summary.-The reliability of three adult visual perceptual tests was investigated. Participants aged 20 years and older (N = 221; 49 adults with neurological impairment, 172 adults without) completed the Developmental Test of Visual Perception-Adolescent and Adult (DTVP-A), the Motor-Free Visual Perception Test-3 (MVPT-3), and the Test of Visual Perceptual Skills (non-motor) Third Edition (TVPS-3). Participants (n = 46) without neurological impairment completed these tests twice. Cronbach's alpha for the DTVP-A, MVPT-3, and TVPS-3 total scales were .86, .74, and .80 and test-retest correlations .51, .71, and .72, respectively.     

Are hand-grip and knee extension strength reflective of a common construct?

Grip and knee extension strength have each been used to characterize muscle strength. Whether grip and knee extension strength reflect a common construct was investigated. Bilateral isometric grip and knee extension strength measures obtained by dynamometry were retrieved from the records of 34 adults who were at least 60 years of age (M = 80.2 yr., SD = 8.1) and had diverse non-focal diagnoses or problems. Relations between measurements were examined using Pearson correlations, Cronbach's alpha, and factor analysis. Pearson correlations (r = .55 to .89), Cronbach's alpha (.88), and factor analysis (loadings .85 to .91) all suggest that grip and knee extension strength reflect a common construct. Either grip or knee extension strength, therefore, may be adequate to characterize limb muscle strength in older adults who are receiving physical therapy for diverse non-focal diagnoses or problems. Nevertheless, the measurement of grip strength may be preferred because it is easier.     

The Racial and Ethnic Microaggressions Scale (REMS): construction, reliability, and validity

Racial microaggressions are subtle statements and behaviors that unconsciously communicate denigrating messages to people of color. In recent years, a theoretical taxonomy and subsequent qualitative studies have introduced the types of microaggressions that people of color experience. In the present study, college- and Internet-based samples of African Americans, Latina/os, Asian Americans, and multiracial participants (N = 661) were used to develop and validate the Racial and Ethnic Microaggression Scale (REMS). In Study 1, an exploratory principal-components analyses (n = 443) yielded a 6-factor model: (a) Assumptions of Inferiority, (b) Second-Class Citizen and Assumptions of Criminality, (c) Microinvalidations, (d) Exoticization/Assumptions of Similarity, (e) Environmental Microaggressions, and (f) Workplace and School Microaggressions, with a Cronbach's alpha of .912 for the overall model and subscales ranging from .783 to .873. In Study 2, a confirmatory factor analysis (n = 218) supported the 6-factor model with a Cronbach's alpha of .892. Further analyses indicate that the REMS is a valid measure of racial microaggressions, as evidenced by high correlations with existing measures of racism and participants' feedback. Future research directions and implications for practice are discussed.     

Linguistic communication and the semantics/pragmatics distinction

Most people working on linguistic meaning or communication assume that semantics and pragmatics are distinct domains, yet there is still little consensus on how the distinction is to be drawn. The position defended in this paper is that the semantics/pragmatics distinction holds between (context-invariant) encoded linguistic meaning and speaker meaning. Two other ‘minimalist’ positions on semantics are explored and found wanting: Kent Bach’s view that there is a narrow semantic notion of context which is responsible for providing semantic values for a small number of indexicals, and Herman Cappelen and Ernie Lepore’s view that semantics includes the provision of values for all indexicals, even though these depend on the speaker’s communicative intentions. Finally, some implications are considered for the favoured semantics/pragmatics distinction of the fact that there are linguistic elements (lexical and syntactic) which do not contribute to truth-conditional content but rather provide guidance on pragmatic inference.     

Flourishing of Students in a Tertiary Education Institution in South Africa

The aims of this study were to examine the relationship between flourishing and academic performance (AP), life satisfaction (SWT), and positive affect (PA). A quantitative cross-sectional survey design was used on a convenience sample of university students (n = 845). The Mental Health Continuum Long Form (MHC-LF), Positive and Negative Affect Scale (PANAS) and Satisfaction with Life Scales (SWLS) were administered. Academic performance was determined through averaging all the participants' modules for the first semester. Individuals with moderate levels of flourishing typically performed in the ‘above average’ to ‘excelling academically’ range. Furthermore, a large number of individuals who were underperforming were also languishing. Flourishing students experienced higher levels of positive affect and life satisfaction, as well as lower levels of negative affect than their languishing and moderately flourishing counterparts. The relationship between flourishing and academic performance is complex, it would seem that flourishing/languishing plays a role in academic performance. Finally, flourishing relates to both PA and SWL, which supports the construct validity of flourishing's conceptualisation.     

Psychometric properties of the Spanish version of the Thougth-Shape Fusion Questionnaire

The objectives of the study were to analyze the psychometric properties, factor structure and internal consistency of the Spanish version of the Thought-Shape Fusion Questionnaire (TSF-Q), as well as to determine its validity by evaluating the relationship of the TSF-Q to different instruments. Two groups were studied: one comprising 146 patients with a diagnosis of anorexia (n = 82), bulimia (n = 33) or unspecified eating disorder (n = 31), and another group of 115 undergraduates with no history of psychological disorder. All participants completed the TSF-Q, TAF-Q, EDI-2, STAI, BDI and SCL-90-R. Differences in TSF-Q scores between the diagnostic subgroups were also analyzed. Two factors were obtained which coincided with the two sections indicated by the authors of the questionnaire: conceptual and interpretative. The internal consistency of the TSF-Q and its subscales was determined by means of Cronbach's alpha, with values ranging between .93 and .96. The correlations with other instruments reflected adequate validity. There were no significant differences between the diagnostic subgroups. The Spanish version of the TSF-Q meets the psychometric requirements for measuring thought-shape fusion and shows adequate internal consistency and validity.     

The Swedish version of the parent-rated Junior Temperament and Character Inventory (J-TCI)

To evaluate the psychometric characteristics of the Swedish version of the Junior Temperament and Character Inventory (J-TCI), it was sent to parents of 9- and 12-yr.-old twins in Sweden. The final number of responders was 196 parents who rated 92 female and 104 male twin pairs. The inventory of one twin, randomly chosen from each pair, was included in the analyses. Reward Dependence, Persistence, and Cooperativeness were scored higher in girls; Novelty Seeking was higher in the 9-yr.-olds and Persistence in the 12-yr.-olds. Pearson's correlations showed that some dimensions were not statistically independent from each other, even if the covariance was moderate. Internal consistency (Cronbach's alpha) was satisfactory for Harm Avoidance, Novelty Seeking, Self-Directedness, and Cooperativeness (.68-.81), while it was lower in those dimensions that had fewer items. The Swedish parent version of the J-TCI shared about the same psychometric characteristics as found in international samples.     

Y haplogroups and aggressive behavior in a Pakistani ethnic group

Studies show that personality dimensions such as aggression are influenced by genetic factors and that allelic variants located on the Y chromosome influence such behavior. We investigated polymorphisms on the male-specific region of the human Y chromosome in 156 unrelated males from the same ethnic background, who were administered the Punjabi translation of the Buss and Perry Aggression Questionnaire that measures four aspects that constitute aggressive behavior, i.e. physical aggression, verbal aggression, anger, and hostility. A value of .85 for Cronbach's coefficient alpha indicates considerable internal consistency and suggests that the psychometric properties of the aggression questionnaire can be adapted for the Pakistani population. A mean score+/-SD of 69.70+/-19.95 was obtained for the questionnaire. Each individual was genotyped following a phylogenetic hierarchical approach to define evolutionary Y haplogroups. Five Y haplogroups that are commonly found in Eurasia and Pakistan comprised 87% (n=136) of the population sample, with one haplogroup, R1a1, constituting 55% of the sampled population. A comparison of the total and four subscale mean scores across the five common Y haplogroups that were present at a frequency > or =3% in this ethnic group revealed no overall significant differences. However, effect-size comparisons allowed us to detect an association of the haplogroups R2 (Cohen's d statistic=.448-.732) and R1a1 (d=.107-.448) with lower self-reported aggression mean scores in this population.     

Psychometric properties of the Spanish version of the self-perception profile for children

Harter's Self-perception Profile for Children was designed to assess children's domain-specific judgments of their competence (scholastic, social, athletic, physical, and behavioral), as well as global self-worth. The psychometric properties and exploratory factor analysis of the profile for two Spanish samples of children (49% boys and 51% girls; M age=11.1 yr., SD=9.7), were examined (n=23 from an after-school social care center in an economically deprived neighborhood and n=120 from a private school mainly enrolling families of medium socioeconomic status). All attending children between 9 and 12 yr. old were included. Analysis showed sex differences, with girls scoring lower than boys on Athletic Competence and higher on Behavioral Conduct. Children from the economically deprived group had higher scores on Social Acceptance and lower scores on Physical Appearance. The cross-cultural analysis showed that the Spanish control group scored significantly higher than the original American control group on Global Self-worth. A Spanish validation with 9- to 12-yr.-olds clearly replicated the five-factor structure reported by Harter in 1985 and also replicated the results obtained in other European samples, showing reliable and valid psychometric properties.

Natural teeth and cognitive function in humans

A number of neurobiological, psychological and social factors may account for cognitive impairment. In animal studies a relation between dental status and cognitive performance has been found. It is unclear whether such a relation exists for humans. In a first step we compared the performance of 1,351 participants (53% women, 47% men; age M = 54.0) with natural teeth to 487 edentulous participants (59% women, 41% men; age M = 71.3) on 12 cognitive tests. The natural teeth group had a lower mean age, fewer women, more years of education, higher mini-mental state (MMSE), and performed significantly higher on several cognitive tests. In a subsequent analysis, the cognitive performance of a subset of the participants (50-85 years) was examined. In this analysis, 211 had natural dentition and 188 were edentulous. The groups were matched for gender, age, social variables, diseases, stress and MMSE. The cognitive disadvantage of the edentulous group was still apparent. The results suggest that functional natural teeth relate to relatively preserved cognitive functioning in older age.     

Depression and cognitive impairment in disability-free early multiple sclerosis

Cognitive and emotional capabilities were evaluated in 73 female patients with stable relapsing-remitting definite, and/or laboratory-supported multiple sclerosis (MS) and were compared with 32 matched healthy controls. Patients were categorized according to their score in the expanded disability status scale (EDSS) to either no (EDSS 0, n = 33) or few clinical signs (EDSS 1-2, n = 40) of MS without physical disability. Patients with EDSS > 0 were characterized by significantly (p < 0.001) higher scores on "von Zerssen's" depression scale, compared to controls. Patients with higher EDSS scores (1-2) showed significantly decreased performance with respect to the total score of Kimura's Recurring-Figures-Test (p < 0.001), in addition. Regarding visuo-constructive functioning, patients with EDSS=0 performed to a significantly lower level (p < 0.001), compared to controls. These results indicate that depression may present as an early sign in MS followed by cognitive impairment, in particular visuo-spatial short-term memory, before physical disability appears. Neuropsychological tests as mentioned here could serve as early diagnostic tools to detect subtle disease progression and to initiate and monitor disease modifying therapies.     

The semantics/pragmatics interface from an experimental perspective: the case of scalar implicature

In this paper I discuss some of the criteria that are widely used in the linguistic and philosophical literature to classify an aspect of meaning as either semantic or pragmatic. With regards to the case of scalar implicature (e.g. some Fs are G implying that not all Fs are G), these criteria are not ultimately conclusive, either in the results of their application, or in the interpretation of the results with regards to the semantics/pragmatics distinction (or in both). I propose a psychologically relevant criterion, that of the primary or secondary role of context. This criterion applies to sub-personal processes that derive the interpretation of a scalar term rather than to the eventual interpretation of the term, and there exist well-established experimental paradigms that can generate quantitative data. I present recent studies on scalar implicature which employ such off-line and real-time paradigms, aiming to demonstrate how research on the semantics/pragmatics distinction can benefit from experimental investigation.     

Predicting intention to use condoms in homosexual men: an application and extension of the theory of reasoned action

A questionnaire based upon the Theory of Reasoned Action was developed and tested to identify predictors of intention to use condoms. Behavioral intentions, attitudes and subjective normative beliefs, behavioral norms, and age of HIV-positive status were included on the questionnaire. Internal consistency of the four components was high, with Cronbach's alpha coefficients of 0.76-0.87. Qualitative data were collected over 2 months from 194 homosexual men who participated in Sydney's homosexual community. Participants aged 17-64 years of mean age 29.5 attended individual interviews or small focus groups to discuss their views concerning condom use. 15% reported having tested HIV-positive, 59% tested negative, and 26% reported not knowing their HIV serostatus. According to logistic modeling, the significant predictors of intentions to use a condom were attitudes and behavioral norms, while HIV antibody positive status and age directly influence behavioral intentions to use a condom. About 50% of men over age 25 years intended to use a condom, irrespective of HIV status. Overall, 59% of men aged 25 years and younger intended to use a condom; 22% of HIV-positive men and 63% of HIV-negative men.     

Willingness to use microbicides varies by race/ethnicity, experience with prevention products, and partner type.

OBJECTIVE: To investigate women's willingness to use vaginal microbicides to reduce/prevent HIV infection, using measures grounded in the individual, behavioral, and social contexts of sex. DESIGN: A cross-sectional study that enrolled a sample (N = 531) of 18-55 year old Latina, African-American, and White women in the U.S. between October, 2004, and July, 2005. MAIN OUTCOME MEASURES: Willingness to use microbicides and individual- and context-related variables (e.g., demographics, relationship status). RESULTS: Exploratory and confirmatory factor analyses supported a one-dimensional, 8-item scale, with high internal consistency (alpha = .91). Subgroup analyses within the Latina (n = 166), African- American (n = 193), and White sub-samples (n = 172) also supported a unidimensional scale with strong internal validity and high reliability. Race/ethnicity as a contextual factor, a woman's history of using prevention products, and the nature of the sexual partnership were predictive of willingness to use microbicides (R = .41). That is, women with greater frequencies of condom use, a history of spermicide use, and non-main sexual partners had higher predicted Willingness to Use Microbicides scale scores, while White women had lower predicted scores. CONCLUSION: The Willingness to Use Microbicides scale serves as the first psychometrically validated measure of factors related to microbicide acceptability. Developing and implementing psychometrically validated and contextualized microbicide acceptability measures, in an effort to understand microbicide users and circumstances of use, is crucial to both clinical trials and future intervention studies.     

Development and validation of the Childhood Perfectionism Inventory (I.P.I.)

There are a few studies linking children's perfectionism with diverse internalized or externalized disorders. Likewise, in Spanish, there is no scale that measures the diverse aspects that comprise it. This paper presents the Children's Perfectionism Inventory (IPI). The sample comprised 2,260 participants (51.2% males and 48.8% females). The age range is between 8 and 13 years (mean= 9.94 and SD= 1.27). Sampling was stratified and random. Of the sample, 78.1% are from public education and 21.9% from private education. 16.2% reside in rural areas and 83.8% in urban areas. To study the validity of the questionnaire, cross-validation was performed. Initially three factors were obtained through exploratory factor analysis: Self-assessment, Self-imposed and External Pressures, with adequate reliability indices (Cronbach's alpha= .89, .87 and .88, respectively). Subsequently, using a confirmatory method, it was found that the three initial factors were explained by a single second-order factor called Perfectionism.
