Reliability, construct validity, and subscale norms of the Brief Symptom Inventory when administered to bereaved parents.

The Brief Symptom Inventory (BSI) was administered to parents (N = 260; 171 mothers and 89 fathers) whose adolescent and young adult children died unexpectedly and violently by accident, homicide, or suicide. Summary statistics and reliability coefficients (Cronbach's alpha) for the nine subscales and the Global Severity Index were calculated. A comparison of means and standard deviations confirmed the expectation that this sample is dramatically different from the normative American community standard. Raw scores for the subscales were transformed into standardized T scores and critical values for a screening heuristic presented. An attempt to obtain construct validity using factor analysis suggested that a five-factor solution provided a description of this population of bereaved parents that is more insightful than the nine standard subscales of the BSI. Implications for both clinicians and future research are discussed.

Loneliness, affect, and self-concept: construct validity of the Bradley Loneliness Scale.

Loneliness is a painful effect probably universally experienced but which has been long neglected in the psychological literature. This study is an extension of the work begun by Rosalee Bradley in developing a self-report instrument for measuring loneliness. It tests the hypothesis that subjects who score higher differ significantly from those scoring low on the loneliness scale on mood: anxiety, depression, anger, vigor, fatigue, confusion, and differ significantly in self-concept as well. Results using data of 208 subjects on the Profile of Mood States, Tennessee Self-Concept Scale, and Bradley Loneliness Scale support this hypothesis and also support the construct validity of the Bradley Loneliness Scale.

Social anxiety and fear of negative evaluation: construct validity of the BFNE-II.

The Brief Fear of Negative Evaluation Scale [BFNE; Leary, M. R. (1983). A brief version of the Fear of Negative Evaluation Scale. Personality and Social Psychology Bulletin, 9, 371-375] is a self-report measure designed to assess fear of negative evaluation, a characteristic feature of social anxiety disorders [Rapee, R. M., & Heimberg, R. G. (1997). A cognitive-behavioral model of anxiety in social phobia. Behaviour Research and Therapy, 35, 741-756]. Recent psychometric assessments have suggested that a 2-factor model is most appropriate, with the first factor comprising the straightforwardly worded items and the second factor comprising the reverse-worded items [Carleton, R. N., McCreary, D., Norton, P. J., & Asmundson, G. J. G. (in press-a). The Brief Fear of Negative Evaluation Scale, Revised. Depression & Anxiety; Rodebaugh, T. L., Woods, C. M., Thissen, D. M., Heimberg, R. G., Chambless, D. L., & Rapee, R. M. (2004). More information from fewer questions: the factor structure and item properties of the original and brief fear of negative evaluation scale. Psychological Assessment, 2, 169-181; Weeks, J. W., Heimberg, R. G., Fresco, D. M., Hart, T. A., Turk, C. L., Schneier, F. R., et al. (2005). Empirical validation and psychometric evaluation of the Brief Fear of Negative Evaluation Scale in patients with social anxiety disorder. Psychological Assessment, 17, 179-190]. Some researchers recommend the reverse-worded items be removed from scoring [e.g., Rodebaugh, T. L., Woods, C. M., Thissen, D. M., Heimberg, R. G., Chambless, D. L., & Rapee, R. M. (2004). More information from fewer questions: the factor structure and item properties of the original and brief fear of negative evaluation scale. Psychological Assessment, 2, 169-181; Weeks, J. W., Heimberg, R. G., Fresco, D. M., Hart, T. A., Turk, C. L., Schneier, F. R., et al. (2005). Empirical validation and psychometric evaluation of the Brief Fear of Negative Evaluation Scale in patients with social anxiety disorder. Psychological Assessment, 17, 179-190]; however [Carleton, R. N., McCreary, D., Norton, P. J., & Asmundson, G. J. G. (in press-a). The Brief Fear of Negative Evaluation Scale, Revised. Depression & Anxiety; Collins, K. A., Westra, H. A., Dozois, D. J. A., & Stewart, S. H. (2005). The validity of the brief version of the fear of negative evaluation scale. Journal of Anxiety Disorders, 19, 345-359] recommend that these items be reworded to maintain scale sensitivity. The present study examined the reliability and validity of the BFNE-II, a version of the BFNE evaluating revisions of the reverse-worded items in a community sample. A unitary model of the BFNE-II resulted in excellent confirmatory factor analysis fit indices. Moderate convergent and discriminant validity were found when BFNE-II items were correlated with additional independent measures of social anxiety [i.e., Social Interaction Anxiety & Social Phobia Scales; Mattick, R. P., & Clarke, J. C. (1998). Development and validation of measures of social phobia scrutiny fear and social interaction anxiety. Behaviour Research and Therapy, 36, 455-470], and fear [i.e., Anxiety Sensitivity Index; Reiss, S., & McNally, R. J. (1985). The expectancy model of fear. In S. Reiss, R. R. Bootzin (Eds.), Theoretical issues in behaviour therapy (pp. 107--121). New York: Academic Press. and the Illness/Injury Sensitivity Index; Carleton, R. N., Park, I., & Asmundson, G. J. G. (in press-b). The Illness/Injury Sensitivity Index: an examination of construct validity. Depression & Anxiety). These findings support the utility of the revised items and the validity of the BFNE-II as a measure of the fear of negative evaluation. Implications and future research directions are discussed.

Construct validity of the Relationship Profile Test: links with attachment, identity, relatedness, and affect.

Studies suggest that overdependence and detachment have negative effects on psychological adjustment, health, and therapy process and outcome. In contrast, healthy dependency (ie., flexible, situation-appropriate help and support seeking) has beneficial effects in each of these areas. In this investigation, 90 college students (50 women and 40 men) completed a battery of personality scales including the Relationship Profile Test (RPT), a 30-item measure of destructive overdependence, dysfunctional detachment, and healthy dependency. RPT scores showed the expected patterns of subscale intercorrelations, gender differences, and links with measures of attachment style, identity, relatedness, and affect. Implications of these results for the construct validity of the RPT are discussed in the context of theoretical models of dependency-detachment.

Scale reliability and construct validity: a pilot study among primary school children in Northern Tanzania.

Based on the World Health Organization's standardized survey inventories assessing AIDS-related knowledge, attitudes, beliefs, and practices (KABP) for adolescents, a written questionnaire was developed and pilot tested among primary school children in Northern Tanzania. Subjects included 472 fifth and sixth graders at four schools in Arusha and Kilimanjaro regions. Results indicated that the large majority of the students understood the questions and were able and willing to complete the survey. Non-response patterns did not seem to be related to the sensitivity of included questions. AIDS-related knowledge and attitudes toward engaging in sexual behavior had acceptable reliability and construct validity when compared with similar surveys in Western countries, while perceived social norms and self-efficacy need further development. KABP questionnaires may serve as a useful method in AIDS-related surveys and evaluation studies among school children in Tanzania if survey instruments are adapted to reflect the local social and cultural context.

Construct validation of the Dutch version of the impact of event scale.

The Impact of Event Scale (ES; M. J. Horowitz, N. Wilner, & W. Alvarez, 1979) is a worldwide-used self-report measure to assess the frequency of intrusive and avoidant phenomena after a variety of traumatic experiences. The purpose of this article is to assess the psychometric value of the Dutch version of the IES (D. Brom & R. J. Kleber, 1985) in several samples of individuals who had experienced various traumatic stressors. The reliability and structure of the IES were evaluated in 3 different samples (total N = 1.588). The reliability of the Dutch version of the IES was adequate across the various stressors. The construct validity was assessed by using confirmatory factor analyses. Outcomes revealed a robust structure over the various samples, generally supporting the composition of the original IES.

Replication and construct validation of the Barrow Neurological Institute Screen for Higher Cerebral Function with a Swedish population.

A Swedish translation of the Barrow Neurological Institute Screen for Higher Cerebral Functions was administered to 52 normal control subjects and 36 patients with well-documented brain dysfunction. Findings replicated those reported in American samples. Level of performance was strikingly similar between Swedish controls and American controls, especially in individuals between 15 and 39 years. Swedish patients with brain dysfunction performed at levels significantly below the Swedish control subjects. The sensitivity of the test was 83% (correctly classifying 30 of 36 patients); patients with a higher level of education were misclassified. The present study replicates earlier findings and adds to the construct validity of the Barrow Neurological Institute Screen. This test may also prove useful for studying rehabilitation outcomes in Swedish patients.

Pain measurement: construct validity of the affective dimension of the McGill Pain Questionnaire with chronic benign pain patients.

The research reported here used a population of chronic benign pain patients and examined the relationship between scores in the affective dimension of the McGill Pain Questionnaire and independent measures of affect and infirmity The data indicated that patients who reported high affective dimensional scores were significantly more depressed and anxious and somatized more than patients who reported low effective scores. Similarly, these high affective patients reported significantly greater perceived infirmity secondary to their pain. These results suggest that the affective dimension score of the McGill Pain Questionnaire can serve as a useful index of the overall affective status of pain patients and given this interpretation the dimension has good construct validity.

The Yale-Brown Obsessive Compulsive Scale: factor analysis, construct validity, and suggestions for refinement.

The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is widely acknowledged as the gold standard measure of obsessive-compulsive disorder (OCD) symptom severity. Despite its popularity, a number of questions remain regarding the Y-BOCS' psychometric properties including: (a) whether obsessional and compulsive symptoms contribute independently to global OCD severity and (b) whether the Y-BOCS subscales are valid with respect to other measures of OCD. We examined these issues in a sample of 100 patients with a diagnosis of OCD. While our confirmatory factor analyses failed to reproduce any previously reported models of the Y-BOCS factor structure, exploratory factor analysis indicated a two-factor solution that assessed symptom severity (i.e., time, distress, and interference from obsessions and compulsions) as separate from resistance and control of obsessions and compulsions. In contrast to the Resistance/Control Subscale, the Severity Subscale demonstrated good psychometric properties and construct validity. Based on our findings we recommend revisions to scoring the Y-BOCS.

Investigating the construct validity of the dissociative taxon: stability analyses of normal and pathological dissociation.

Research has suggested the existence of a pathological dissociative taxon. However, relatively little is known about this taxon. This study examined the 2-month retest stability of this taxon--together with other measures of dissociation and the Big Five--in a sample of 465 undergraduates. Contrary to expectation, taxon scores were only modestly stable and were substantially less stable than the other measures, including continuous indicators of dissociation. Furthermore, most individuals who were identified as taxon members at one assessment were classified as nonmembers at the other. These results challenge the existence of a pathological dissociative taxon. More generally, these data demonstrate that statistically identified taxa need to be explicated through the normal process of construct validation.

An assessment tool for brachial plexus regional anesthesia performance: establishing construct validity and reliability.

BACKGROUND AND OBJECTIVES: Technical proficiency in regional anesthesia is often determined subjectively through in-training evaluations. Objective assessment tools improve these evaluations by providing criteria for measurement. However, any evaluation instrument needs to be valid and reliable before it is adopted into a curriculum. The purpose of this study is to determine the validity and reliability of a devised assessment of residents performing an interscalene brachial plexus block (ISB). METHODS: In this prospective study, 10 junior trainees and 10 senior trainees were videotaped performing an ISB. Junior trainees were defined as in their first year of anesthetic training and had performed less than 10 ISBs independently. Senior trainees had completed at least 1 year of anesthesia training and had performed greater than 10 ISBs independently. Two blinded expert raters independently evaluated the performance of the ISB using a checklist and global rating scale. Construct validity was established if the assessments were able to reliably discriminate between different levels of training. RESULTS: Senior trainees performed an ISB significantly better than junior trainees when assessed using the global rating scale (P < .05) and checklist (P < .001). The overall interrater reliability for the global rating scores was excellent (r = 0.85, P < .05) and was good for the checklist scores (r = 0.74, P < .05). CONCLUSIONS: Both assessment modalities were valid, in that they reliably discriminated between different levels of training. Objective measures of technical skills are feasible, timely, and improve the validity and reliability of competency assessments.

Development and construct validation of a measure of attitudes toward public exposure to sexual stimuli.

Developed a brief, reliable, and valid measure of attitudes toward public exposure to sexual stimuli. Both advocates and opponents of public exposure to such stimuli typically cite presumed effects upon children. Consequently many of the Likert format items in the several versions of the scale deal with prescriptive and prescriptive beliefs about the exposure of children to sex related stimuli. Over a three-year period five different groups of respondents participated in the study. Both the longer and the shorter versions of the scale administered to these groups appear to have acceptable reliabilities. In an attempt to provide construct validation information, the relationships between the Acceptance of Public Sexuality Scale and several measures of traditionalism were examined. As expected, scores on the scale were inversely related to measures of traditionalism and positively related to measures of modernity Possible uses of the scale were discussed.

Construct validity of the auditory continuous performance test for preschoolers.

Development of diagnostic instruments directed toward neuropsychological assessment of preschoolers lags significantly behind those available for school-age children (DeWolfe, Byrne, & Bawden, 2000). This is particularly true for measures of executive function (EF). The Auditory Continuous Performance Test for Preschoolers (ACPT-P; Mahone, Pillion, & Hiemenz, 2001) is a computerized, Go-No-go test developed to measure selected EF skills in preschoolers. First, to determine whether performance on the ACPT-P is associated with hearing impairment, we compared performance of children with mild hearing loss (MHL) to controls on the ACPT-P, and measures of spatial working memory (SWM) and motor persistence (MP). There were no differences between performance of the MHL group and controls on any of these measures. Second, to examine the construct validity of the ACPT-P, we compared performance of 40 preschoolers with ADHD to 40 age- and sex-matched controls, using the ACPT-P to measure response preparation, sustained attention, and inhibitory control. We also compared these groups on measures of SWM and MP. The group with attention deficit hyperactivity disorder (ADHD) performed significantly worse than controls on the ACPT-P (omissions, mean response time, variability) and MP. The ACPT-P was correlated with the MP, but not with the SWM measure. Both the ACPT-P and the MP measures showed low to moderate correlations with parent ratings of behavior associated with ADHD. These findings support the use of performance-based assessment of executive control skills in preschoolers suspected of having ADHD. In this age group, the ACPT-P may be particularly useful in assessing sustained attention and response preparation and may complement behavior rating scales.

Cortical and subcortical constructs of the dean-woodcock sensory motor battery: a construct validity study.

The factor structure of the Dean-Woodcock Sensory Motor Battery was examined using exploratory factor analysis with promax rotation. Participants (n = 1,651) were composed of 701 neurologically impaired individuals and 950 normal individuals. Three factors, accounting for almost 58.2% of the total test variation, emerged from the data and were labeled Simple Sensory Skills, Motor and Complex Sensory Skills, and Subcortical Motor Skills and Auditory/Visual Acuity. Hypothesized cross loadings were present, especially between the first two factors, which highlighted the parallel nature of sensory-motor skills. The third factor demonstrated the least amount of cross loadings, which reinforced the demarcation of cortical and subcortical motor skills measured by the DWSMB. The results also indicated that the factors were separated by the complexity of the cortical sensory-motor tasks. The factor structure, combined with an analysis of the interfactor correlations, provides evidence for construct validity of the DWSMB.

Action (verb) fluency: test-retest reliability, normative standards, and construct validity.

Action (verb) fluency is a newly developed verbal fluency task that requires the examinee to rapidly generate as many verbs (i.e., "things that people do") as possible within 1 min. Existing literature indicates that action fluency may be more sensitive to frontal-basal ganglia loop pathophysiology than traditional noun fluency tasks (e.g., animal fluency), which is consistent with the hypothesized neural dissociation between noun and verb retrieval. In the current study, a series of analyses were undertaken to examine the psychometric properties of action fluency in a sample of 174 younger healthy participants. The first set of analyses describes the development of demographically adjusted normative data for action fluency. Next, a group of hypothesis-driven correlational analyses reveals significant associations between action fluency and putative tests of executive functions, verbal working memory, verbal fluency, and information processing speed, but not between action fluency and tests of learning or constructional praxis. The final set of analyses demonstrates the test-retest stability of the action fluency test and provides standards for determining statistically reliable changes in performance. In sum, this study enhances the potential clinical applicability of action fluency by providing demographically adjusted normative data and demonstrating evidence for its reliability and construct validity.

The Body Esteem Scale: construct validity of the female subscales.

The female subscales of the Body Esteem Scale (BES) have demonstrated convergent and discriminant validity in two previous studies. However, relationships between BES dimensions, weight, and other body-image measures have not been adequately examined. In this study, 200 women with a mean age of 27.6 years completed the BES, the Eating Disorder Inventory, the Self-Consciousness Scale, the Tennessee Self-Concept Scale, a figure rating task, a phototechnical body-size estimation procedure, and items concerning weight satisfaction and attractiveness. BES Weight Concern was most closely related to weight variables and other body image measures where BES Sexual Attractiveness and Physical Condition were more strongly associated with less specific self-perceptions and attitudes. Results support the construct validity of the BES female subscales and their utility for research in populations at increased risk for body-image or eating-disorder disturbances.

Effects of affective-semantic mode of item presentation in balanced self-report scales: biased construct validity of the Zung Self-rating Depression Scale.

The widely applied procedure of balancing self-report instruments by including positively and negatively keyed items is exemplified by the Zung Self-rating Depression Scale (SDS). Investigation of the influence of the symptom-positive and symptom-negative item modes on the SDS in a depressed population resulted in two major findings. First, the reversed scoring of the symptom-negative items resulted in higher mean item scores. Secondly, factor analyses of the SDS in the present study and in previous research revealed that the semantic modes of item presentation were represented in the factor structure of the SDS. These findings were confirmed by analyses with the State-Trait Anxiety Inventory (STAI) and by previous factor analytical research with balanced instruments and were interpreted within the framework of the theory of Positive and Negative Affect. The present data cast doubts on the construct validity of the SDS as a measure of depressive symptomatology due to the presence of the negatively keyed items and suggest reconsideration of the use of balanced instruments for minimization of the acquiescence response set.

Continued construct validation of the St. Marys CVA Evaluation: Bilateral Awareness Scale.

Previous research suggested that scores on the Schenkenberg Line Bisection Test of unilateral neglect should correlate significantly with bilateral awareness ratings on the St. Marys CVA Evaluation, but that scores on both of these instruments should not correlate with St. Marys perceptual scores. To test this hypothesis, occupational therapists at St. Marys Hospital Medical Center administered the Schenkenberg test and St. Marys CVA Evaluation to 26 cerebral vascular accident (CVA) patients. Spearman rho coefficients were computed. As hypothesized, the correlation between the Schenkenberg test scores and St. Marys bilateral awareness ratings reached statistical significance, and no significant relationship was found between Schenkenberg scores and St. Marys perceptual scores. However, there was a significant relationship between the St. Marys bilateral awareness ratings and perceptual scores. This result may indicate that clinical observations are not adequate to discriminate between unilateral neglect and perceptual impairments. The results further the construct validation process of the St. Marys CVA Evaluation. The data also support the position that unilateral neglect is not primarily a perceptual phenomenon.
