Internal reliability and convergent validity of the Depression-Happiness Scale with the General Health Questionnaire in an employed adult sample

Salmonella Typhimurium was isolated from a fresh fecal sample of zebra finches (Poephila guttata) in December 1992 on an aviary where a large scale outbreak of S. Typhimurium infection among bengalees (a variety of Lonchura striata) in 1991 had been recorded. The isolates from zebra finches were examined for antibiotic sensitivity and plasmids, which were 60 Mdal, then they showed the same pattern as those of S. Typhimurium isolated at the previous outbreak. This is the first report of S. Typhimurium isolation from zebra finches.     

The Schwartz Cancer Fatigue Scale: testing reliability and validity

Fructo-oligosaccharides (FOS) are new food ingredients that are able to beneficially affect the host by selectively stimulating the growth and/or activity of colonic bifidobacteria (concept of prebiotics). A commercial enzyme preparation was found to possess a high fructosyltransferase activity and could be used as a biocatalyst for the industrial production of FOS from sucrose. Under optimum conditions (pH: 5.5, temperature: 55 degrees C and 7 units of fructosyltransferase activity per gram sucrose), in presence of glucose (competitive inhibitor) the actual yield reached the theoretical value (up to 50%). Actually, FOS that are commercially available for their prebiotic properties belong to inulin type with low degree of polymerisation (DP:3 to 10). Our FOS were identified by both HPLC and 13C-NMR spectrometry as neo-FOS type (neo-kestose, neo-nystose and neo-fructofuranosylnystose), a new structure which is very close to inulin type (same linkage between fructosyl units). The neo-FOS may act as a prebiotic factor due to their structural similarity with inulin type.     

Self-Injurious Thoughts and Behaviors Interview: Development, reliability, and validity in an adolescent sample.

The authors developed the Self-Injurious Thoughts and Behaviors Interview (SITBI) and evaluated its psychometric properties. The SITBI is a structured interview that assesses the presence, frequency, and characteristics of a wide range of self-injurious thoughts and behaviors, including suicidal ideation, suicide plans, suicide gestures, suicide attempts, and nonsuicidal self-injury (NSSI). This initial study, based on the administration of the SITBI to 94 adolescents and young adults, suggested that the SITBI has strong interrater reliability (average κ = .99, r = 1.0) and test-retest reliability (average κ = .70, intraclass correlation coefficient = .44) over a 6-month period. Moreover, concurrent validity was demonstrated via strong correspondence between the SITBI and other measures of suicidal ideation (average κ = .54), suicide attempt (κ = .65), and NSSI (average κ = .87). The authors concluded that the SITBI uniformly and comprehensively assesses a wide range of self-injury-related constructs and provides a new instrument that can be administered with relative ease in both research and clinical settings.

The Ostomy Adjustment Scale: Further evidence of reliability and validity.

Administered M. E. Olbrisch's (see record 1985-21769-001) 34-item ostomy adjustment scale (OAS) to 164 volunteers (aged 18–75 yrs) who underwent ostomy surgery. 30 Ss also completed the 17-item short version of the OAS. Support for the 34-item scale's test–retest and internal consistency reliability and construct validity was demonstrated. Internal consistency reliability of the short form was disappointing. Ostomy adjustment was significantly related to quality of life and negatively related to depression. Four clear factors, corresponding to 3 of Olbrisch's factors emerged: normal functioning, functional limitations, negative affect, and positive affect.

Mississippi Scale for Combat-Related Posttraumatic Stress Disorder: Three studies in reliability and validity.

The Mississippi Scale for Combat-Related Posttraumatic Stress Disorder is a 35-item self-report scale derived from Diagnostic and Statistical Manual of Mental Disorders (DSM-III) criteria for the disorder. This article describes a series of three studies designed to explore the psychometric properties of the scale. Study 1 used 362 Vietnam veterans seeking help at Vet Centers (Operation Outreach) to confirm the internal consistency of the instrument and provide an assessment of its factor structure. Study 2 demonstrated the high test–retest reliability of the instrument over a period of 1 week. Study 3 indicated that the test's sensitivity was .93, specificity was .89, and overall hit rate was .90 when it was used to differentiate between a posttraumatic stress disorder (PTSD) group and two non-PTSD comparison groups. The utility of the test when it is administered within the context of a multiaxial approach to assess military-related PTSD is discussed.

UCLA Loneliness Scale (Version 3): reliability, validity, and factor structure

In this article I evaluated the psychometric properties of the UCLA Loneliness Scale (Version 3). Using data from prior studies of college students, nurses, teachers, and the elderly, analyses of the reliability, validity, and factor structure of this new version of the UCLA Loneliness Scale were conducted. Results indicated that the measure was highly reliable, both in terms of internal consistency (coefficient alpha ranging from .89 to .94) and test-retest reliability over a 1-year period (r = .73). Convergent validity for the scale was indicated by significant correlations with other measures of loneliness. Construct validity was supported by significant relations with measures of the adequacy of the individual's interpersonal relationships, and by correlations between loneliness and measures of health and well-being. Confirmatory factor analyses indicated that a model incorporating a global bipolar loneliness factor along with two method factor reflecting direction of item wording provided a very good fit to the data across samples. Implications of these results for future measurement research on loneliness are discussed.     

The reliability and validity of the Perceived Stigmatization Questionnaire (PSQ) and the Social Comfort Questionnaire (SCQ) among an adult burn survivor sample.

In this study, 361 adult burn survivors completed the Perceived Stigmatization Questionnaire (PSQ), the Social Comfort Questionnaire (SCQ), and other measures. Both the PSQ and SCQ had good internal consistency indices. Factor analysis of the PSQ yielded 3 factors (absence of friendly behavior, confused/staring behavior, and hostile behavior). The SCQ had 1 factor. Conjoint factor analysis with measures of related constructs (body esteem, body-esteem importance, depression, social support) suggested that PSQ and SCQ measure distinct constructs. Correlations with the related psychosocial constructs and burn characteristics suggested the PSQ and SCQ have good convergent and discriminant validity. Limitations of the study are discussed.

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. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

The validity and reliability of the Violence Risk Scale: A treatment-friendly violence risk assessment tool.

The development of risk assessment tools that use dynamic variables to predict recidivism and to inform and facilitate violence reduction interventions is the next major challenge in the field of risk assessment and management. This study is the first in a 2-step process to validate the Violence Risk Scale (VRS), a risk assessment tool that integrates violence assessment, prediction, and treatment. Ratings of the 6 static and 20 dynamic VRS variables assess the client's level of risk. Ratings of the dynamic variables identify treatment targets linked to violence, and ratings of the stages of change of the treatment targets assess the client's treatment readiness and change. The VRS scores of 918 male offenders showed good interrater reliability and internal consistency and could predict violent and nonviolent recidivism over both short- and longer term (4.4-year) follow-up. The probability of violent and nonviolent recidivism varied linearly with VRS scores. Dynamic and static variables performed equally well. The results support the contention that the VRS can be used to assess violent risk and to guide violence reduction treatment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Development and validation of a Coping with Discrimination Scale: Factor structure, reliability, and validity.

Four studies were conducted to develop and validate the Coping With Discrimination Scale (CDS). In Study 1, an exploratory factor analysis (N = 328) identified 5 factors: Education/Advocacy, Internalization, Drug and Alcohol Use, Resistance, and Detachment, with internal consistency reliability estimates ranging from .72 to .90. In Study 2, a confirmatory factor analysis (N = 328) provided cross-validation of the 5-factor model as well as evidence for validity of the scale. The validity evidence was similar across racial groups and for males and females. In Study 3, the estimated 2-week test–retest reliabilities (N = 53) were between .48 and .85 for the 5 factors. Education/Advocacy, Internalization, Drug and Alcohol Use, and Detachment were positively associated with active coping, self-blame, substance use, and behavioral disengagement, respectively, providing further support for validity of the CDS. Finally, incremental validity evidence was obtained in Study 4 (N = 220), where it was shown that the CDS explained variance in outcome variables (i.e., depression, life satisfaction, self-esteem, and ethnic identity) that could not be explained by general coping strategies.

The Vancouver Scar Scale: an administration tool and its interrater reliability

The Burn Scar Index, often called the Vancouver Scar Scale, is widely used in clinical practice and research to document change in scar appearance. Several sections of the Index require equipment to accurately score the items. Additionally, the numeric scores are difficult to remember. We recently devised a pocket-sized tool to aid in scoring the scar and to increase staff compliance in use of the Index. With this tool interrater reliability is good, which makes the Burn Scar Index a viable measure for research.     

State–Trait Anger Theory and the utility of the Trait Anger Scale.

Eight studies present support for the state–trait anger theory. In Studies 1–3, high-anger participants reported (a) greater anger in many different provocations, in their most angering ongoing situations, and in daily life, (b) greater anger-related physiological arousal, (c) greater state anger and dysfunctional coping in response to a visualized provocation, and (d) greater use of suppression and outward negative expression of anger. Only heart rate in the visualized provocation did not support predictions. In Studies 4–5, high-anger individuals suffered more frequent and intense anger consequences. In Studies 6–8, trait anger had higher correlations with dimensions of anger than with other emotions, cognitions, and behaviors. Few gender differences were found across studies. Results were discussed in terms of state–trait theory, convergent and discriminant validity for the Trait Anger Scale, anger expression, gender, and the implications for counseling.

Additional support for the reliability and validity of the Modified Scale for Suicide Ideation.

The Modified Scale for Suicide Ideation (MSSI; I. W. Miller et al, 1986) is a self-report measure used to assess suicidality. The present study was designed to provide additional assessment of the psychometric properties of the MSSI by (a) studying it in a severe and chronic sample of suicidal ideators (aged 18–24 years); (b) examining its stability and factor structure; and (c) comparing the MSSI with the Scale for Suicide Ideation (A. Beck et al, 1979), an interview-based measure of suicide ideation. The results provide additional data suggesting that the MSSI has satisfactory reliability and validity and that it can be used as a measure of suicide ideation with some confidence.

New subscales for an anchored version of the Brief Psychiatric Rating Scale: Construction, reliability, and validity in acute psychiatric admissions.

Attending psychiatrists completed an anchored version of the 18-item Brief Psychiatric Rating Scale (BPRS-A) based on admission and evaluation information on a total of 2,921 adult patients treated at 1 public sector acute psychiatric teaching hospital. Exploratory factor analysis was applied to a 6-month sample to construct 4 nonoverlapping subscales: Resistance, Positive Symptoms, Negative Symptoms, and Psychological Discomfort. Confirmatory factor analysis compared these new subscales to 3 other published subscale models using a second 6-month sample. Internal consistency, rater influence, and interrater agreement were estimated in separate studies. Discriminant validity was explored by comparison of diagnosis-based samples. Application of the BPRS-A as a debriefing instrument in the study of symptomatic change and the multiple challenges inherent in psychometric study of such a rating scale in realistic hospital practice are discussed.

Personality and vocational interests in an adult sample.

Examined the relations between vocational typology developed by the 3rd author (1966, 1973) and the neuroticism–extraversion–openness (NEO) model of personality presented by the 1st 2 authors (1980) among 217 males and 144 females, aged 21–89 yrs. Young and old adult groups were similar to college students in most vocational interests, and the same pattern of sex differences was found. Correlations between Self-Directed Search and NEO inventory scores showed strong associations of investigative and artistic interests with openness to experience, and of social and enterprising interests with extraversion. Ss interested primarily in conventional occupations tended to be closed to experience. These associations were generally confirmed when spouse ratings were used as a non-self-report measure of personality traits in a subset of the Ss. The NEO Inventory complements the Holland typology, primarily in providing measures of neuroticsm. Research on the possible utility of supplementing vocational interest data with personality measures is suggested, and some implications for vocational counseling among older adults are discussed.

The Social Phobia Inventory: Validity and reliability in an adolescent community sample.

Social anxiety disorder and social anxiety are highly prevalent psychological conditions in youth. Because of the known risks associated with the spectrum of social anxiety in youth, early detection with valid and reliable assessment measures is imperative. Self-report measures have become the most widely used method of assessment for child and adolescent social anxiety. Because research to date on self-report measures of social anxiety disorder in adolescents is limited, the primary objective of the present study was to contribute to the literature by examining the validity and reliability of a new self-report measure, the Social Phobia Inventory (SPIN), in a community sample of adolescents. The SPIN is a 17-item measure purported to assess the full spectrum of social anxiety disorder symptomatology. Previously, psychometric research on the SPIN in adult populations has demonstrated its validity and reliability. In the current psychometric examination, results revealed strong support for the temporal stability, internal consistency, and construct validity of the SPIN, suggesting it is an appropriate screening measure for the assessment of social anxiety disorder in adolescents.

A new look at an old issue: Manifest Anxiety Scale validity.

Investigated the efficacy of MA scale scores as a measure of situational drive level using 48 undergraduates. The MA scale was used as a dependent variable, i.e., it was administered while drive level was systematically manipulated. Drive state was varied at 4 levels by the induced muscular tension technique while heart rate (HR) and GSR activity were recorded. The physiological measures indicate that drive level was effectively varied; however, no meaningful relationship between MA scale scores and HR and GSR activity was observed. The intercorrelation between HR and GSR was low but significant. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Schizotypy and sustained attention: Confirming evidence from an adult community sample.

Sustained attention deficits represent one of the most robust findings in the study of schizophrenia and schizotypy. However, very little is known about the nature of sustained attention performance and schizotypy in the general adult population. The present study assessed sustained attention performance in a large, normative adult community sample (N = 305) with no history of psychosis using the Continuous Performance Test-identical pairs version (CPT-IP). Associations between overall CPT-IP performance and schizotypal personality disorder features, controlling for the effects of age, sex, and educational level, revealed diminished sensitivity (d', discriminability), and increased random errors were related to increased reality distortion features. These data, drawn from a general population sample, provided support for overall sustained attention deficits as an endophenotype for schizophrenia liability.

Measuring secondhand smoke exposure in babies: The reliability and validity of mother reports in a sample of low-income families.

The reliability and validity of mother's reports of their infants' exposure to secondhand smoke (SHS) were examined in an ethnically diverse sample of low-income, low-education families (N?=?141 mothers). At baseline and posttest, smoking mothers reported about their infants' SHS exposure at different locations and by different sources during the previous week. Findings show that mothers can give reliable accounts of the degree to which they contribute to their babies' SHS exposure. Mothers are able to differentiate between their own smoking behavior and the extent to which they expose their infants. Consistent with the overall exposure pattern, exposure caused by the mother and exposure occurring at home showed the strongest associations with biological and environmental measures. These findings suggest that smoking mothers can provide reliable and valid reports of the degree to which their infants are exposed to SHS. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
