Beyond internal consistency reliability: Rationale and user’s guide for Multitrait Analysis Program on the microcomputer

A methodology for evaluating Likert-type scales is presented. Multitrait scaling is a straightforward approach to scale analysis that focuses on items as the unit of analysis and utilizes the logic of convergent and discriminant validity. Multitrait scaling is illustrated with the Multitrait Analysis Program, using patient satisfaction data from the Medical Outcomes Study.     

Test-retest reliability of the test of nonverbal intelligence (TONI)

Test-retest reliability of the Test of Nonverbal Intelligence (TONI) was investigated. Fifty students randomly selected from first and second grades were administered Form A and Form B of the TONI on two occasions 3 weeks apart. Test-retest correlation coefficients were calculated for all 50 subjects. The results showed high test-retest reliability: Correlation coefficients were .89 (Form A) and .83 (Form B). Parallel form reliability was also high: Form A correlated with Form B .88 on the first administration and .86 on the second administration.     

Forms of Competitive Attitude and Achievement Orientation in Relation to Disordered Eating

The primary focus in this study was anexamination of the differential contributions of twodifferent forms of competitive attitude to disorderedeating in a nonclinical sample of Caucasian universitywomen. The results showed that it is not competitionper se that is a primary contributor to eatingdisorders, but rather a particular form of competitiveattitude. Specifically, hypercompetitiveness was related strongly to eating disorder symptoms, butpersonal development competitiveness was unrelated. Asecond purpose considered the relationship ofcontext-specific measures of achievement to eatingdisorder symptoms. Disordered eating was associatedpositively with the need to achieve in appearance, butnot to a need to achieve in academics and career.Discussion centered on the potential usefulness of these findings in the treatment of women who areeating disordered. It also argued for changes in asocialization process which often leads to thedevelopment of hypercompetitive attitudes and anovervaluing of beauty in American women.     

Daydreaming: a measurable concept

Research has been reported which supports the psychometric properties of the Imaginal Processes Inventory. The purpose was to confirm and extend this research as well as investigate the interrelationships between daydreaming and depression, locus of control, and visual imagery. This inventory (7 scales), Beck Depression Inventory, Rotter Locus of Control Scale (I-E), and Gordon's Test of Visual Imagery Control were administered to 100 female undergraduates. A sample of 39 subjects were retested on the scales an average of 6.8 wk. after the first administration. Correlations with Imaginal Processes Inventory and test-retest data were consistent with Giambra's (1977) findings for males and support the reliability and generalizability of the scores. Other results include significant intercorrelations between the various scales of this inventory and the others. Implications for an understanding of the process of depression are discussed.     

Problem-solving performance of young boys and girls as a function of task appropriateness and sex identity

The problem-solving performance of young boys and girls was examined in three conditions in which good performance was indicated as being appropriate for boys, for girls, or for both boys and girls. The relations between task scores and five sex-role measures were also examined. As predicted, the boys performed significantly more poorly when the task was indicated as one that girls did better. The girls' performance was not affected by the conditions of the study. The girls' problem-solving scores did not differ significantly from the boys' scores. There was some relationship between the task scores and the sex-role measures for boys, but not for girls. Associations among the sex-role measures were not high.This research was supported by a DGES-FCAC research grant from the government of Quebec, Canada.

Implementation of the Sound Partners Reading Program

Eleven first grade and 10 second grade students, all with reading and behavioral difficulties, received one-on-one tutoring using the Sound Partners reading program (Vadasy & Pool, l997). Students received 30 min of tutoring each day for 5 months. Students were assessed on Letter-Word Identification, Passage Comprehension, and Word Attack subtests of the Woodcock-Johnson-Revised (WJ-R): Tests of Achievement. An informal measure (rapid letter naming) was also used. Results indicated that gains of approximately 1 standard deviation (or greater) were noted for subtests of the WJ-R for first-grade students; second graders showed relatively stable performance from pre- to posttest assessments. Similar performance was noted on the informal measure across grades. Program satisfaction data showed that overall the tutors, teachers, and students were pleased with the program. Discussion focuses on the implications for future investigations.     

Psychopathology Following Interpersonal Violence: A Comparison of Risk Factors in Older and Younger Adults

A randomly selected sample of 549 women age 55 years and older and 2,669 women age 18–34 years was interviewed via telephone to determine prevalences of physical and sexual assault, posttraumatic stress disorder (PTSD) symptomatology, and depression. Prevalences of sexual and physical assaults were lower in older compared to younger women. In addition, given a trauma, prevalences and proportionate risk of posttraumatic psychopathology and depression were also lower for older, relative to younger women. Specifically, multivariate analyses revealed that sexual assault predicted only PTSD avoidance in older adults, but all forms of PTSD symptomatology and depression in younger adult women. Similarly, physical assault predicted only PTSD re-experiencing symptoms in older women, but all forms of PTSD symptoms and depression in younger women. Self-reported health status was not associated with any increased risk of psychopathology, and low income predicted increased avoidance and depression only in younger women.     

White Racial Identity and Attitudes Toward People With Disabilities

This empirical study investigated the relationship between racial identity and attitudes toward people with disabilities. Results indicate that higher statuses of racial identity correlate positively while lower and more racist‐oriented statuses correlate negatively with attitudes toward people with disabilities. The study supports the notion that attitudes from cultural memberships associated with power can transfer from one domain (i.e., White/People of Color) to another domain (i.e., Abled/Disabled). Este estudio empírico investigó la relación entre la identidad y actitudes raciales hacia personas con incapacidades. Los resultados indican que las posiciones más altas de la identidad racial se pone en correlación positivamente mientras bajan y más posiciones racista‐orientados se pone en correlación negativamente con actitudes hacia personas con incapacidades. El estudio sostiene la noción que actitudes de asociaciones culturales asociadas con el poder pueden transferir de un dominio (es decir, los Blancos/Personas del Color) a otro dominio (es decir, Capacitados/Incapacitados).     

The psychology of psychiatric genetics: evidence that positive emotions in females moderate genetic sensitivity to social stress associated with the BDNF Val-sup-6-sup-6Met polymorphism

Previous work indicated protective effects of positive emotions on genetically influenced stress sensitivity. Given the fact that expression of brain-derived-neurotrophic-factor (BDNF) is associated with stress-induced behavioral changes, it was hypothesized that the BDNF Val-sup-6-sup-6Met genotype may mediate genetic effects on stress sensitivity, conditional on the level of concurrent positive emotions. Subjects (n=446) participated in a momentary assessment study, collecting appraisals of stress and affect in the flow of daily life. Multilevel regression analyses examined moderation of daily life stress-induced negative affect (NA) by BDNF genotype, and to what degree this was conditional on concurrent positive emotions. Results showed that heterozygous BDNF "Met" carriers exhibited an increased NA response to social stress compared with "Val/Val" subjects. Positive emotions at the time of the stressor decreased BDNF genetic moderation of the NA response to social stress in a dose-response fashion. This effect was most pronounced in BDNF Met carriers. Thus, the impact of BDNF genotype on stress sensitivity is conditional on the experience of positive emotions. Interdisciplinary research in psychology and psychiatric genetics may lead to the improvement of treatment choices in stress-related disorders.
