A Variable Response Inconsistency scale and a True Response Inconsistency scale for the Millon Adolescent Clinical Inventory.

Variable Response Inconsistency (M-VRIN) and True Response Inconsistency (M-TRIN) scales were developed for the Millon Adolescent Clinical Inventory using 104 male and 78 female delinquents, ages 13-17 years. M-VRIN efficacy was assessed by comparing nonrandom protocols of 76 male and 34 female delinquents, ages 13-17 years, with 100 computer-generated random protocols. Nonrandom protocols were screened using a matched-pair Minnesota Multiphasic Personality Inventory-Adolescent or Jesness Inventory. M-TRIN efficacy was assessed by comparing protocols with 160 simulated acquiescent and nonacquiescent protocols. Specificities of .95 or higher showed sensitivities up to .89 for M-VRIN, and .90 and .79 for M-TRIN. Predictive power and overall effectiveness are reported for several base rates. Small relationships may exist between M-VRIN and race, and between M-TRIN and gender.

Likert and Guttman scaling of visual function rating scale questionnaires.

PURPOSE: To test the assumptions underlying Likert scoring of visual function questionnaires. METHODS: Questionnaires were administered to 284 low-vision subjects by telephone. Each subject was administered two of four questionnaires: ADVS, NEI VFQ-25 plus supplement, expanded VAQ, and VF-14. RESULTS: Z-scores for cumulative frequency of using each rating category across subjects are not linear with rating category rank and items are not the same difficulty for any of the questionnaires. Guttmann coefficients of reproducibility ranged from 57% for the ADVS to 51% for the NEI VFQ-25. Cronbach alphas ranged from 0.92 for the VF-14 to 0.96 for the NEI VFQ; however, inter-item consistency coefficients ranged from 0.24 for the VAQ to 0.45 for the NEI VFQ. Likert scores were significantly correlated between instruments, ranging from 0.66 for NEI VFQ vs ADVS to 0.90 for the VF-14 vs. ADVS. CONCLUSIONS: The rating scales of all four questionnaires fail to satisfy Likert's assumptions. Also, ratings are probabilistic, rather than deterministic, which means that the Likert model is not valid for these questionnaires. However, Likert scores for all four instruments are intercorrelated, suggesting that they are monotonic with the latent subject trait distributed in the low vision sample.

Traumatic ureteral injuries: a single institution experience validating the American Association for the Surgery of Trauma-Organ Injury Scale grading scale.

PURPOSE: Ureteral injuries are uncommon and challenging. In this study we report our institutional experience with ureteral injuries. We evaluated the American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS) for ureteral injuries as a predictor of outcomes for complexity of repair, morbidity, mortality and associated injuries. MATERIALS AND METHODS: We performed a retrospective, 120-month study (January 1992 to December 2002) at an urban, level I trauma center. RESULTS: In the 57 patients mean hospital Admission blood pressure +/- SD was 115 +/- 25 mm Hg, mean Revised Trauma Score was 7.38 +/- 0.84 and mean Injury Severity Score was 15 +/- 1.15. The mechanism of injury was penetrating in 55 cases (96.5%), including gunshot wound in 52 (54.5%) and stab wound in 2 (5.5%), and in blunt 2 of motor vehicle accidents (3.5%). The anatomical location was the left side in 33 cases (58%), right side in 23 (40%) and bilateral in 1 (2%). The distribution of injuries was proximal in 15 cases (26%), mid in 21 (37%) and distal in 21 (37%). Associated injuries were present in 56 patients (98%). An intraoperative diagnosis was made in 44 cases (77%). Of the patients 50 (88%) required complex repairs or an adjunct procedure, including a double pigtail stent in 33 (58%), ureteroureterostomy in 20 (35%), ureteroneocystostomy with a psoas hitch in 10 (18%), external diversion in 9 (16%), suprapubic cystostomy in 8 (14%), nephrostomy in 2 (3.5%), nephrectomy in 2 (3.5%) and ligation in 2 (3.5%). Injury grade was I to V in 5 (8%), 8 (13%), 13 (22.8%), 18 (31.6%) and 13 (22.8%) cases, respectively. Overall 51 patients (89%) survived. No deaths were related to ureteral injury. Renal salvage was achieved in 49 of the 51 surviving patients (96%). CONCLUSIONS: Ureteral injuries are uncommon. The complexity of repair and number of associated injuries increase with AAST-OIS injury grade. Mortality increases with AAST-OIS injury grade but it is not related to the ureteral injury. Excellent results can be achieved with complex techniques of primary repair, leading to renal salvage.

Shadows of the planck scale: scale dependence of compactification geometry.

By studying the effects of the shape moduli associated with toroidal compactifications, we demonstrate that Planck-sized extra dimensions can cast significant "shadows" over low-energy physics. These shadows distort our perceptions of the compactification geometry associated with large extra dimensions and place a fundamental limit on our ability to probe the geometry of compactification by measuring Kaluza-Klein states. We also find that compactification geometry is effectively renormalized as a function of energy scale, with "renormalization group equations" describing the "flow" of geometric parameters such as compactification radii and shape angles as functions of energy.

Development and validation of a five-factor sexual satisfaction and distress scale for women: the Sexual Satisfaction Scale for Women (SSS-W).

INTRODUCTION: This article presents data based on the responses of over 800 women who contributed to the development of the Sexual Satisfaction Scale for Women (SSS-W). AIM: The aim of this study was to develop a comprehensive, multifaceted, valid, and reliable self-report measure of women's sexual satisfaction and distress. METHODS: Phase I involved the initial selection of items based on past literature and on interviews of women diagnosed with sexual dysfunction and an exploratory factor analysis. Phase II involved an additional administration of the questionnaire, factor analyses, and refinement of the questionnaire items. Phase III involved administration of the final questionnaire to a sample of women with clinically diagnosed sexual dysfunction and controls. RESULTS: Psychometric evaluation of the SSS-W conducted in a sample of women meeting DSM-IV-TR criteria for female sexual dysfunction and in a control sample provided preliminary evidence of reliability and validity. The ability of the SSS-W to discriminate between sexually functional and dysfunctional women was demonstrated for each of the SSS-W domain scores and total score. CONCLUSION: The SSS-W is a brief, 30-item measure of sexual satisfaction and sexual distress, composed of five domains supported by factor analyses: contentment, communication, compatibility, relational concern, and personal concern. It exhibits sound psychometric properties and has a demonstrated ability to discriminate between clinical and nonclinical samples.

A modified peripheral neuropathy scale: the Overall Neuropathy Limitations Scale.

A new peripheral neuropathy activities measure, the Overall Neuropathy Limitations Scale (ONLS), was derived by modifying the Overall Disability Sum Score (ODSS) slightly. Its inter-rater reliability was found to be high and its correlation with the ODSS (r = 0.97), 36-item Short Form Questionnaire Physical Component Summary Score, and participation and impairment measures was significant. Acceptable responsiveness (standardised response mean 0.76) was shown by the ONLS. The results obtained from the questionnaire agreed closely with those obtained from observation of the tasks on the ONLS, but were not equivalent. The simplicity of the ODSS is shared by the ONLS, but the ONLS has better content validity and less ceiling effect, which may make it more useful for clinical practice and research.

Behavior Rating Scale for Dementia: development of test scales and presentation of data for 555 individuals with Alzheimer's disease.

We studied 555 Alzheimer's disease patients on the Behavior Rating Scale for Dementia (BRSD), which uses informant interviews to measure behavioral pathology in demented patients. For the 45 items, ratings of present ranged from 5% to 66% of the subjects, with 39 rated present in at least 10%. Twenty-nine items were significantly correlated with dementia severity. The mean number of items present per subject was 13.5; only two subjects had none rated present. Factor analysis identified six factors common to mildly and moderately demented subjects. Six subscales were developed: Depressive Symptoms, Inertia, Vegetative Symptoms, Irritability/Aggression, Behavioral Dysregulation, and Psychotic Symptoms. Interitem consistency was high for three subscales (alpha's from .75 to .80) and moderate for three (alpha's from .48 to .56). Four subscale scores and total scores were significantly but weakly correlated with dementia severity. Detailed results and test instructions are presented in the BRSD manual, available from The Consortium to Establish a Registry for Alzheimer's Disease.

Construct validation of scales derived from the Rorschach method: a review of issues and introduction to the Rorschach rating scale.

I suggest the main goal of Rorschach validation should be a refined understanding of what each score means. Toward this end, I review general issues in construct validity, hurdles unique to the Rorschach, and general limitations with validation criteria. I then recommend two approaches for improving criteria so they can begin approximating the gold standards that are necessary for a refined understanding of what scores actually measure. The first is a method for improving expert clinical judgment, and the second is a method for aggregating data across diverse judges. Finally, the Rorschach Rating Scale (RRS) is presented as a criterion tool to be used with either of these approaches to validation. The RRS is a fairly comprehensive summary of the constructs thought to be measured by various Rorschach scoring systems. The utility of the RRS for research and training are discussed, as are other practical, theoretical, and psychometric issues in its application.

On the depth and scale of metabolic rate variation: scaling of oxygen consumption rates and enzymatic activity in the Class Cephalopoda (Mollusca).

Recent ecological theory depends, for predictive power, on the apparent similarity of metabolic rates within broad taxonomic or functional groups of organisms (e.g. invertebrates or ectotherms). Such metabolic commonality is challenged here, as I demonstrate more than 200-fold variation in metabolic rates independent of body mass and temperature in a single class of animals, the Cephalopoda, over seven orders of magnitude size range. I further demonstrate wide variation in the slopes of metabolic scaling curves. The observed variation in metabolism reflects differential selection among species for locomotory capacity rather than mass or temperature constraints. Such selection is highest among epipelagic squids (Lolignidae and Ommastrephidae) that, as adults, have temperature-corrected metabolic rates higher than mammals of similar size.

[Drug Compliance Scale. I. Development of the Drug Compliance Scale].

The failure of patients to comply with treatment regimens recommended by their physicians is a significant clinical problem. Researches on the assessment of compliance have, however, been precluded by methodological difficulties such as lack of adequate measures. The purpose of this study was to develop a self-administered questionnaire to evaluate drug compliance. First, questionnaire containing a 52-items complied by two doctors, a pharmacist and a nurse, was tested on 81 outpatients, all volunteers, attending the departments of psychosomatic medicine and internal medicine. Four items were temporarily removed for later analysis because they directly inquired about drug compliance (drug compliance items). The other 48 items were analyzed and three factors consisting of 26 items were further studied: expectation on taking medicine, rejection to taking medicine and seeking knowledge of drugs. Chronback's alpha coefficients representing internal consistency of the three factors were sufficiently high (ranging from .75 to .84). Furthermore, we preformed a simplified pill count to validate the 4 drug compliance items. There was a weak to moderate correlation between the result of pill count and each of 4 drug compliance items. A new self-administered questionnaire of 30 items was thus developed and named the Drug Compliance Scale.

Coarse spatial scales constrain the range of binocular fusion on fine scales.

To examine interactions among spatial scales in disparity processing, we have measured the upper disparity limit for binocular single vision (the diplopia threshold) for high-spatial-frequency test stimuli in the presence of cosine gratings of lower spatial frequency that defined a surface in depth. When the frequency of this grating surface was 2.0 octaves below that of the test, the test fusion range was reduced by a factor of 3-4 relative to the condition in which no grating surface was present. However, gratings 4.0 octaves below the test frequency had no effect, and the test and grating were seen transparently at different depths. Further experiments indicate that the effect is orientation specific and that high-frequency gratings do not affect low-frequency tests. Finally, experiments using grating surfaces tilted in depth indicate that fusion at high spatial frequencies is constrained to a range centered on the local disparity of the surface defined by the lower frequency. These results are important for computational models for stereopsis that are based on coarse-to-fine matching strategies.

[Actual conditions of occupational health activities in small-scale enterprises in Japan: system for occupational health, health management and demands by small-scale enterprises].

In order to clarify the real conditions of occupational health services (OHS) in small-scale enterprises (SSEs) in Japan, we analyzed questionnaires recovered from 765 SSEs in the area of a city neighboring Osaka City (recovery rate, 69.3%). The SSEs included 358 SSEs with 1 to 4 workers (46.8% of total SSEs), 203 with 5 to 9 (26.5%), 163 with 10 to 29 (21.3%) and 41 with 30 to 49 (5.4%). The main types of businesses were manufacturing (374, 48.9% of total SSEs), wholesale/retail trade/restaurants (153, 20.0%), community, social and personal services (132, 17.3%) and construction (72, 9.4%). Health examinations were performed in 47.7% of SSEs. The reason for the lack of examinations were "shortage of time" (33.3% of SSEs lacking health examination) and "employees do not want to be examined" (28.1%). Some health promotion measures were conducted in 29.2% of SSEs. Health examination (59.0% of SSEs), health promotion (36.5%), measure of mental health (25.9%) and information service for employers and employees (25.5%) were demanded by SSEs as OHS. Financial subsidies and economical incentives were demanded by 46.4% and 28.8% of SSEs, respectively. Regional occupational health center in this area was poorly known among SSEs (8.2%), but health examination (48.4%), information service (37.5%), assessment of work method and advice to improve (19.8%) and environment measurement (12.4%) are demanded of the center by SSEs.

Broad factor scales of the 16 PF Fifth Edition and Millon personality disorder scales: a replication.

This study is a replication of the link between broad personality factors from the 16 PF and personality disorder scales based on Millon's typology of personality. The current study was done with the new version of the 16 PF during the final stages of norming. The sample consisted of 30 female and 2 male undergraduate and graduate students, ranging in age from about 21 to 60 years. The data from this replication are consistent with results of the earlier study in that 15 of the 18 expectations were in the expected direction. Of these 10 were significant.

Preconditions for sensitivity in measuring change: visual analogue scales compared to rating scales in a Likert format.

In a study of preconditions of responsiveness, we examined the variances obtained by two different ways of responding to questionnaire items. Subjects were 168 first-year medical students. They all completed a questionnaire of nine items. The original Likert-like scoring was (partially) replaced by visual analogue scoring in three quarters of the questionnaires. For three items the analogue form had a significantly greater variance than the discrete form, but no discrete item had a significantly greater variance than its analogue counterpart. Assuming that a greater variance was indicative for a greater responsiveness, our findings provide some support for the preferred use of analogue scales over discrete response categories in the measurement of changes over time.

Time perspective of substance abuse patients: comparison of the scales in Stanford Time Perspective Inventory, Beck Depression Inventory, and Beck Hopelessness Scale.

This study examined the correlations between the Stanford Time Perspective Inventory, the Beck Depression Inventory, and the Beck Hopelessness Scale for an in-patient substance-abuse population of 50. Analysis did not support the hypothesis that substance abusers would be more likely to be present-hedonistic and present-fatalistic rather than past- or future-oriented. However, the results modestly supported the hypothesis that future orientation would be negatively correlated with scores on depression and hopelessness measures. In this sample, there was a slight tendency toward the time orientations of future- and present-fatalistic. Correlations among scores on the three measures were generally low (range = .06 to -.38).
