Instrument Development With Web Surveys and Multiple Imputations

This article outlines the development of a tool to assess psychosocial needs in U.S. Air Force (USAF) units. Instrument development began with the construction of an item taxonomy, pretesting procedures (Q-sort; cognitive interviews), and a pilot web survey to document internal consistency and test-retest reliability, followed by two large-scale Web surveys to derive a viable factor structure. Because certain items (e.g., child care) were not relevant to all respondents, multiple imputations to replace missing values were necessary before factor analyses could proceed. Exploratory factor analyses of data from the first Web survey revealed an eight-factor solution; and data from the second Web survey confirmed that the eight-factor solution could be replicated on an independent sample. Developed in accordance with psychometric principles, the final assessment tool tapped a range of psychosocial factors spanning quality of work life, community life, family functioning, and personal well-being.     

Social Stigma and its Consequences for the Socially Stigmatized

This paper presents an integrative review of current and classic theory and research on social stigma and its consequences for the socially stigmatized. Specific attention is paid to stigma‐related processes surrounding race/ethnicity, gender, and sexual orientation. The origins and perpetration of social stigma are discussed alongside perspectives on how stigmatized groups and individuals experience stigma‐related stress. Consideration is given to responses to stigma in the form of coping, social support, and meaning‐making processes. Both the potential negative and positive consequences of social stigma are highlighted in this review through the integration of predominant social psychological theory with emerging critical and feminist theories of positive marginality and resistance. The paper culminates in a theoretical process model designed to provoke future theory and research that share its integrative aims.     

Community implementation of PMTO™: Impacts on referrals to specialist services and schools

Sigmarsdóttir, M. & Björnsdóttir, A. (2012). Community implementation of PMTO?: Impacts on referrals to specialist services and schools. Scandinavian Journal of Psychology 53, 506–511. In 2000, the city of Hafnarfjörður, Iceland, implemented Parent Management Training – Oregon Model (PMTO^?) to prevent and treat behavioral problems among children. This paper describes the implementation and findings regarding impacts in the community. As hypothesized, findings showed that the number of referrals to specialist services decreased in Hafnarfjörður following PMTO implementation and increased in two comparison communities not implementing the method. Within the Hafnarfjörður community, recorded instances of behavior problems reduced in elementary schools working in line with PMTO. The results presented are the first such findings in Iceland and suggest the kinds of systematic changes communities may experience following the implementation of an evidence‐based program.     

Neuropsychological correlates of psychopathology in an unselected cohort of young adolescents

Members of a birth cohort were assessed for psychopathology and neuropsychological dysfunction at age 13. Ss who met DSM-III criteria for a single disorder, multiple disorders, and no disorder were compared on 5 composite neuropsychological measures. The multiple disorders group performed significantly worse than did the nondisordered group on the Verbal, Visuospatial, Verbal Memory, and Visual-Motor Integration factors. They also showed the highest rate of neuropsychological impairment. The attention-deficit disorder group performed significantly worse than did the nondisordered group on the Verbal Memory and Visual-Motor Integration factors, and the anxiety disorder group performed significantly worse than did the nondisordered group on the Visual-Motor Integration factor. Results suggest that neuropsychological dysfunction is more often associated with multiple rather than single, psychiatric disorders in adolescents. The problem of comorbidity in studies of neuropsychological function in childhood and adolescent psychopathology is highlighted.     

Comparison of the geometric and the contrast models of similarity by presentation of visual stimuli to the left and the right visual fields

In this study we investigated by means of the "same-different" decision task the process of comparing visual stimuli (schematic faces, familiar objects, houseplants, and nonsense figures) when presented for 100-150 msec to the right or to the left visual hemifields. The analysis of incorrect "same" responses showed that the addition of a common component (e.g., glasses, buttons) to a pair of nonidentical stimuli increased the percentage of incorrect same responses whereas the addition of the same component to one stimulus only in the pair decreased the percentage of incorrect "same" responses. This pattern, which is in accordance with Tversky's contrast model of similarity, is incompatible with any geometric model. Second, for schematic faces the results revealed that the left hemisphere is more sensitive to common than to distinctive features, whereas the right hemisphere is more sensitive to distinctive than to common features. No such interaction was obtained for the other type of stimuli. The implications of these results for models of similarity and the difference between the present findings and the findings of Sergent (1984) are discussed.     

An examination of an appropriateness index and its effect on validity coefficients

Differences in validity coefficients were examined for both an appropriately responding group and an inappropriately responding group on four computer adaptive tests. Appropriate responding occurs when an examinee follows a clear pattern in answering test items relative to item difficulties. An Appropriateness Index score is computed based on Item Response Theory item parameters. The subjects were 155 college students from a medium sized midwestern university. The procedure required the subjects to complete four computer adaptive tests, as well as four criterion measures. High and low appropriateness groups were then formed by splitting the groups based on median values. The differences in validity coefficients were then examined for each of the four tests. All validity coefficients were smaller for the inappropriate groups, however only two of the four differences were significant. The appropriateness index was found to be an important factor in the consideration of validity coefficients.Portions of this paper were presented at the 34th Annual meeting of the Southeastern Psychological Association, March 31, 1988, New Orleans, Louisiana.Preparation of this article was supported in part by London House, Inc.

The relationship of the Yale-Brown Obsessive Compulsive Scale (YBOCS) to other measures of obsessive compulsive symptoms in a nonclinical population

The Yale-Brown Obsessive Compulsive Scale (YBOCS; Goodman, Price, Rasmussen, & Mazure, 1989a) is an interview-based rating scale measuring severity of obsessive compulsive disorder (OCD). Because it is independent of the number and type of OCD symptoms and minimizes confounding with other types of symptoms, it has become the "gold standard" for assessing the outcome of behavioral and pharmacological treatments. This study was designed to further validate the YBOCS in relation to self-report measures of obsessive compulsive phenomena in a nonclinical population. Among a group of 45 female college students, the three primary YBOCS measures (obsessions, compulsions, and total score) were internally consistent and correlated moderately to strongly with self-report measures of obsessive compulsive phenomena that have been used in previous research. The compulsive subscale of the YBOCS showed the lowest correlation with self-report measures sharing only 25% of the common variance. This measure is appropriate for use with nonclinical samples and may prove superior to other instruments for detecting the presence and severity of obsessive and compulsive symptoms.     

ORTHOGRAPHIC REPRESENTATION AND PHONEMIC SEGMENTATION IN SKILLED READERS:

Abstract— The long-lasting effect of reading experience in Hebrew and English on phonemic segmentation was examined in skilled readers Hebrew and English orthographies differ in the way they represent phonological information Whereas each phoneme in English is represented by a discrete letter, in un-pointed Hebrew most of the vowel information is not conveyed by the print, and, therefore, a letter often corresponds to a CV utterance (i. e., a consonant plus a vowel) Adult native speakers of Hebrew or English, presented with words consisting of a consonant, a vowel, and then another consonant, were require to delete the first "sound" of each word and to pronounce the remaining utterance as fast as possible Hebrew speakers deleted the initial CV segment instead of the initial consonant more often than English speakers, for both Hebrew and English words Moreover, Hebrew speakers were significantly slower than English speakers in correctly deleting the initial phoneme, and faster in deleting the whole syllable. These results suggest that the manner in which orthography represents phonology not only affects phonological awareness during reading acquisition, but also has a long-lasting effect on skilled readers' intuitions concerning the phonological structure of their spoken language.     

Factors affecting the onset and magnitude of linear vection

The role of central and peripheral vision in the production of linear vection was assessed by using displays in which flow structure and sources of internal and external depth information were manipulated. Radial optical flow was more effective for inducing self-motion in both central and peripheral visual fields than was lamellar flow in displays of the same size. The presence of external occlusion information was necessary to induce linear vection when small displays were composed of lamellar flow, whereas the effectiveness of small radial displays did not depend on the availability of occlusion edges.     

Cognitive-behavioral treatment of compulsive hoarding: a multiple baseline experimental case study

The present case study describes a cognitive-behavioral intervention directed at helping a 53 year old female suffering from compulsive hoarding decrease clutter and improve decision-making and sorting techniques. The intervention focused on decision-making training, exposure and response prevention, and cognitive restructuring. Ratios of cluttered space to overall space were calculated for floor and furniture tops for each of five rooms over a period of 17 months. Clutter decreased substantially in each of the rooms targeted for intervention, while clutter ratios remained stable for a room used as a baseline control (no intervention). In addition, D.'s scores on self-report measures of obsessive-compulsive symptomatology decreased after 9 months of intervention suggesting that the treatment protocol affected symptoms of hoarding distress, as well as clutter. Despite previously reported difficulties in the treatment of compulsive hoarding, our results provide preliminary evidence that a cognitive-behavioral intervention can be successful in reducing hoarding symptoms. Suggestions for future research include streamlining the treatment program and testing its efficacy on large clinical samples.
