The development of a Money Attitude Scale.

On the basis of the clinical and theoretical literature, 62 items in the domains of security, retention, and power-prestige were generated. Factor analysis yielded five factors: power-prestige, retention-time, distrust, quality, and anxiety. A 29-item Money Attitude Scale (MAS) was developed on the basis of four of these factors. Reliability measures, as well as personality and psychopathological correlations, were determined and discussed.

Developing a rating scale for projected stories.

The Six-part Story Method (6PSM) is a projective tool in wide use by dramatherapists in the UK, USA and Israel (Lahad & Ayalon, 1993). In contrast to projective tests used by psychotherapists and psychologists, the 6PSM has never been the subject of any validation or reliability studies. This study reports on the identification of scale items to describe the manifest content of six-part stories. In all, 26 statements with acceptable inter-rater reliability have been identified. These statements were used to rate stories produced by clinicians (N = 24) mainstream community mental health patients (N = 21) and patients with a borderline personality disorder (N = 19). Some features that were expected to be indicators of an author with a BPD diagnosis proved to be as common in stories from other authors. However, a scale of eight items was identified that differentiated well between authors with a BPD diagnosis and others, with adequate test-retest and inter-rater reliability. Concurrent validity was tested against the Structured Clinical Interview for DSM-IV Axis II (SCID-II), the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM) and the Inventory of Interpersonal Problems--Short Form (IIP-32).

Visual, cognitive, and language assessments at 39 months: a follow-up study of children fed formulas containing long-chain polyunsaturated fatty acids to 1 year of age.

OBJECTIVE: Docosahexaenoic acid (DHA) and arachidonic acid (ARA) are long-chain polyunsaturated fatty acids found in breast milk and recently added to infant formulas. Their importance in infant nutrition was recognized by the rapid accretion of these fatty acids in the brain during the first postnatal year, reports of enhanced intellectual development in breastfed children, and recognition of the physiologic importance of DHA in visual and neural systems from studies in animal models. These considerations led to clinical trials to evaluate whether infant formulas that are supplemented with DHA or both DHA and ARA would enhance visual and cognitive development or whether conversion of linoleic acid and alpha-linolenic acid, the essential fatty acid precursors of ARA and DHA, respectively, at the levels found in infant formulas is sufficient to support adequately visual and cognitive development. Visual and cognitive development were not different with supplementation in some studies, whereas other studies reported benefits of adding DHA or both DHA and ARA to formula. One of the first trials with term infants that were fed formula supplemented with DHA or both DHA and ARA evaluated growth, visual acuity (Visual Evoked Potential; Acuity Card Procedure), mental and motor development (Bayley Scales of Infant Development), and early language development (MacArthur Communicative Developmental Inventories). Growth, visual acuity, and mental and motor development were not different among the 3 formula groups or between the breastfed and formula-fed infants in the first year of life. At 14 months of age, infants who were fed the formula with DHA but no ARA had lower vocabulary production and comprehension scores than infants who were fed the unsupplemented control formula or who were breastfed, respectively. The present follow-up study evaluated IQ, receptive and expressive vocabulary, visual-motor function, and visual acuity of children from the original trial when they reached 39 months of age. METHODS: Infants were randomized within 1 week after birth and fed a control formula (n = 65), one containing DHA (n = 65), or one containing both ARA and DHA (n = 66) to 1 year of age. A comparison group (n = 80) was exclusively breastfed for at least 3 months after which the infants continued to be exclusively breastfed or were supplemented with and/or weaned to infant formula. At 39 months, standard tests of IQ (Stanford Binet IQ), receptive vocabulary (Peabody Picture Vocabulary Test-Revised), expressive vocabulary (mean length of utterance), visual-motor function (Beery Visual-Motor Index), and visual acuity (Acuity Card Procedure) were administered. Growth, red blood cell fatty acid levels, and morbidity also were evaluated. RESULTS: Results were analyzed using analysis of variance or linear regression models. The regression model for IQ, receptive and expressive language, and the visual-motor index controlled for site, birth weight, sex, maternal education, maternal age, and the child's age at testing. The regression model for visual acuity controlled for site only. A variable selection model also identified which of 22 potentially prognostic variables among different categories (feeding groups, the child and family demographics, indicators of illness since birth, and environment) were most influential for IQ and expressive vocabulary. A total of 157 (80%) of the 197 infants studied at 12 months participated in this follow-up study. Characteristics of the families were representative of US families with children up to 5 years of age, and there were no differences in the demographic or family characteristics among the randomized formula groups. As expected, the formula and breastfed groups differed in ethnicity, marital status, parental education, and the prevalence of smoking. Sex, ethnicity, gestational age at birth, and birth weight for those who participated at 39 months did not differ from those who did not. The 12-month Bayley mental and motor scores and 14-month vocabulary scores of the children who participated also were were not different from those who did not. At 39 months, IQ, receptive and expressive language, visual-motor function, and visual acuity were not different among the 3 randomized formula groups or between the breastfed and formula groups. The adjusted means for the control, ARA+DHA, DHA, and breastfed groups were as follows: IQ scores, 104, 101, 100, 106; Peabody Picture Vocabulary Test, 99.2, 97.2, 95.1, 97.4; mean length of utterance, 3.64, 3.75, 3.93, 4.08; the visual-motor index, 2.26, 2.24, 2.05, 2.40; and visual acuity (cycles/degree), 30.4, 27.9, 27.5, 28.6, respectively. IQ was positively associated with female sex and maternal education and negatively associated with the number of siblings and exposure to cigarette smoking in utero and/or postnatally. Expressive language also was positively associated with maternal education and negatively associated with the average hours in child care per week and hospitalizations since birth but only when the breastfed group was included in the analysis. The associations between maternal education and child IQ scores are consistent with previous reports as are the associations between prenatal exposure to cigarette smoke and IQ and early language development. Approximately one third of the variance for IQ was explained by sex, maternal education, the number of siblings, and exposure to cigarette smoke. Growth achievement, red blood cell fatty acid levels, and morbidity did not differ among groups. CONCLUSIONS: We reported previously that infants who were fed an unsupplemented formula or one with DHA or with both DHA and ARA through 12 months or were breastfed showed no differences in mental and motor development, but those who were fed DHA without ARA had lower vocabulary scores on a standardized, parent-report instrument at 14 months of age when compared with infants who were fed the unsupplemented formula or who were breastfed. When the infants were reassessed at 39 months using age-appropriate tests of receptive and expressive language as well as IQ, visual-motor function and visual acuity, no differences among the formula groups or between the formula and breastfed groups were found. The 14-month observation thus may have been a transient effect of DHA (without ARA) supplementation on early vocabulary development or may have occurred by chance. The absence of differences in growth achievement adds to the evidence that DHA with or without ARA supports normal growth in full-term infants. In conclusion, adding both DHA and ARA when supplementing infant formulas with long-chain polyunsaturated fatty acids supports visual and cognitive development through 39 months.

Relation of light and exercise to seasonal depressive symptoms: preliminary development of a scale.

The palliative effects of exercise on depression are neither generally accepted nor clearly understood. On the contrary, the efficacy of light exposure in the treatment of seasonal depressive symptoms is widely recognized. It is possible that the contradictory findings in the exercise and depression literatures are due to a failure to consider light exposure as a variable. 32 women who regularly exercised were administered a depression inventory and the Seasonal Light Inventory, a new measure composed of two 10-item subscales, Seasonality and Light Exposure. Seasonality assesses fluctuations of mood, appetite, sleep, and other activities occurring at similar times each year, and the Light Exposure subscale measures respondents' estimated exposure to outdoor and bright indoor light. Indeed, those exercisers whose habits exposed them to a relatively large amount of light reported fewer seasonal depressive symptoms than those whose habits exposed them to a relatively small amount of light. The results suggest that the puzzling relationship between exercise and depression might be delineated more clearly by considering light exposure as a confounding variable.

Systematic review of the quality of randomized controlled trials for patellofemoral pain syndrome.

STUDY DESIGN: Systematic review of the literature. OBJECTIVES: To develop a grading scale to judge the quality of randomized clinical trials (RCTs) and conduct a systematic review of the published RCTs that assess nonoperative treatments for patellofemoral pain syndrome (PFPS). BACKGROUND: Systematic reviews of the quality and usefulness of clinical trials allow for efficient synthesis and dissemination of the literature, which should facilitate clinicians' efforts to incorporate principles of evidence-based practice in the clinical decision-making process. METHODS AND MEASURES: Using a scale based on criteria in the Cochrane Collaboration Handbook, we sought to critically appraise the methodology used in RCTs related to the nonoperative management of PFPS, synthesize and interpret our results, and report our findings in a user-friendly fashion. A scale to assess the methodological quality of trials was designed and pilot tested for its content and reliability. Published RCTs identified during a literature search were then selected and rated by 6 raters. We used predefined cutoff scores to identify specific weaknesses in the clinical research process that need to be improved in future clinical trials. RESULTS: The quality scale we developed was demonstrated to be sufficiently reliable to warrant interpretation of the reviewers' findings. The percentage of trials that met a minimum level of quality for each specific criterion ranged from a low of 25% for the adequacy of the description of the randomization procedure to a high of 95% for the description and standardization of the intervention. CONCLUSIONS: Based on the results of trials exhibiting a sufficient level of quality, treatments that were effective in decreasing pain and improving function in patients with PFPS were acupuncture, quadriceps strengthening, the use of a resistive brace, and the combination of exercises with patellar taping and biofeedback. The use of soft foot orthotics in patients with excessive foot pronation appeared useful in decreasing pain. In addition, at a short-term follow-up, patients who received exercise programs were discharged earlier from physical therapy. Unfortunately, most RCTs reviewed contained qualitative flaws that bring the validity of the results into question, thus diminishing the ability to generalize the results to clinical practice. These flaws were primarily in the areas of randomization procedures, duration of follow-up, control of cointerventions, assurance of blinding, accountability and proper analysis of dropouts, number of subjects, and the relevance of outcomes. Also, given the limited number of high-quality clinical trials, recommendations about supporting or refuting specific treatment approaches may be premature and can only be made with caution.

A scale for the measurement of attitudes toward physically disabled adults.

The ATDPs have been the instruments most commonly used for the measurement of attitudes toward disabled persons. However, it has become increasingly apparent that these scales have serious shortcomings and that a new scale is due. A New Scale was developed for the purpose of measuring attitudes towards permanently and seriously physically disabled adults. The subjects used for the development of this scale consisted of students studying for a Bachelor of Science degree in physiotherapy. The scale has 50 scored statements and 25 interest statements. The scored statements were created so that they could not be answered on the basis of factual knowledge, and would be difficult to answer on the basis of remembered experience and reasonable argument. The interest statements did not contribute to the subject's score and were included for the purpose of keeping the subject's interest in responding to all the statements on the scale. A psychometric analysis of the 50 scored statements demonstrated that the New Scale has excellent discriminative ability, internal consistency, and reliability, good validity, and that the influence of agreement response and social desirability is minimal. In addition it is believed that the New Scale has a high degree of unidimensionality.

[Development of a scale to measure the effectiveness of oriental nursing education].

PURPOSE: The aim of this study was to design and evaluate a scale for measuring reliability and validity in the field of oriental nursing education. METHOD: A questionnaire was administered to 495 university nursing students using a convenience sampling method. The period of time for collecting data was from September 2003 to January 2004. RESULT: The derived outcome tool consisted of 6 factors and 22 inquires on the basis of a conceptual frame of three domains (knowledge, attitude, and skill), As a result of the item analysis, 22 items were selected and the internal consistency alpha coefficient was .767. The value of Cronbach' Alpha of knowledge (factor 1) was .885, attitude (factor 2) was .756, and skill (factor 3) was .610. The three factors accounted for 65.110% of the variance in the total scale. Addressing the explanatory variance of each domain Cognitive domain was 22.477%, affective domain was 20.543%, and psychomotor domain was 17.090%. CONCLUSION: Further studies need to be done to verify educational evaluation and apply our outcomes to oriental nursing education.

[Covariation of parental judgments of child behavioral characteristics with a developmental scale and observation of behaviors].

The aim of the present study is the validation of a German questionnaire that was designed to assess "infant temperament" by parental judgement. The questionnaire represents an adaptation of Rothbart's "Infant Behavior Questionnaire" (IBQ). It was studied whether the parental judgements concerning positive emotionality, negative emotionality/irritability, motor activity and soothability of the infant are correlated to corresponding observed child behavior. Furthermore we tried to determine influences of parental characteristics on their judgements. 31 First-born healthy 4 months old infants were observed in their home environment as well as in the video laboratory of our institute. The Bayley Scales of Infant Development (Mental Scale) were applied. The mothers filled in the Temperament Questionnaire and scales to assess maternal depression and anxiety. We yielded the expected significant correlations for the scales measuring positive and negative emotionality, and motor activity with the observed behavioral characteristics of the infants. Independent of these results the mothers' judgements of their infant's positive and negative emotionality was associated with maternal depression. We can therefore conclude that the two scales contain subjective and objective elements that are independent of each other.

[Development of a scale for assessing lack of motivation in elderly persons].

OBJECTIVE: Apathy is made of depression and of loss of motivation. For patients with senile dementia of Alzheimer-type, the MMS score is inversely correlated with apathy and depression. The aim of this study is to build a scale aimed at loss of motivation and validated for elderly people. METHODS: The study was performed on 44 non-demented elderly people, 54 outpatients with dementia, mainly Alzheimer's type. After agreement of the patients and the family, patients were assessed using different scales: Cornell's for depression, Marin's for apathy, MMS for cognitive disorders. At the same time, we tested with caregivers a 21 items indirect scale listing various disorders related to loss of motivation, scored from 1 to 4: very often, often, sometimes, never. Patients were retested by 7 different caregivers, and different investigators, immediately and a month later to evaluate reproducibility, temporal stability using Cohen's Kappa and Spearman coefficients. The demotivation scale was then correlated with the other scales and Cronbach's alpha coefficient was studied. RESULTS: The 44 non-demented people were 80.25 years old +/- 7.75. 54 demented patients were included: 15 men and 39 women. The mean age was 81.47 years +/- 8.03. As Cohen's Kappa and Spearman coefficients were not sufficient for 6 items, the scale was reduced to 15 items (Presented). The depression scale is strongly and significantly correlated with the Marin's apathy scale. Internal coherence is particularly significant: Cronbach's alpha coefficient = 0.91. For the 54 patients with dementia, the depression score worsens significantly as cognitive disorders worsen. In these patients Marin's scale shows a progression of apathy with the impairment observed in MMS, but the MMS is not correlated with the score at the demotivation scale. So this latter scale seems to measure something close but independent from apathy. DISCUSSION: The loss of motivation is a frequent behavioral disorder in old patients. Loss of motivation can be present in any chronic disease with asthenia. This disorder is frequent in depression, in dementia and even in endocrine disease, for instance hyperthyroidism. It triggers a loss of commitment of old people and paves the way for the loss of autonomy. Apathy is a loss of motivation associated with an affective blunting. Demotivation is congruent with the actual presence of apathy in patients as measured using Marin's scale that has been used as a standard in this study. This paper presents a methodology for an evaluation scale aimed at the loss of motivation in old people. A psychologist and seven different caregivers working in a day care hospital on 98 patients performed an indirect assessment. An estimation of specificity, sensibility, reproducibility and homogeneity was tested with appropriate techniques. The results obtained with this scale answer the preliminary methodological queries, allowing us to trigger further researches for a final validation. According to our results, demotivation does not increase with age neither in demented nor in non-demented patients. Conversely, the aggravation of cognitive disorders in dementia is associated with increasing demotivation and depression. The loss of motivation participates to the learnt and acquired helplessness. Its care is necessarily global, using pharmacological, psychological and sociotherapeutic treatment. CONCLUSION: EAD scale appears a reliable tool to assess loss of motivation in old and very old patients.

Validation of a model for process development and scale-up of packed-bed solid-state bioreactors.

We have validated our previously described model for scale-up of packed-bed solid-state fermenters (Weber et al., 1999) with experiments in an adiabatic 15-dm(3) packed-bed reactor, using the fungi Coniothyrium minitans and Aspergillus oryzae. Effects of temperature on respiration, growth, and sporulation of the biocontrol fungus C. minitans on hemp impregnated with a liquid medium were determined in independent experiments, and the first two effects were translated into a kinetic model, which was incorporated in the material and energy balances of the packed-bed model. Predicted temperatures corresponded well with experimental results. As predicted, large amounts of water were lost due to evaporative cooling. With hemp as support no shrinkage was observed, and temperatures could be adequately controlled, both with C. minitans and A. oryzae. In experiments with grains, strong shrinkage of the grains was expected and observed. Nevertheless, cultivation of C. minitans on oats succeeded because this fungus did not form a tight hyphal network between the grains. However, cultivation of A. oryzae failed because shrinkage combined with the strong hyphal network formed by this fungus resulted in channeling, local overheating of the bed, and very inhomogeneous growth of the fungus. For cultivation of C. minitans on oats and for cultivation of A. oryzae on wheat and hemp, no kinetic models were available. Nevertheless, the enthalpy and water balances gave accurate temperature predictions when online measurements of oxygen consumption were used as input. The current model can be improved by incorporation of (1) gas-solids water and heat transfer kinetics to account for deviations from equilibrium observed with fast-growing fungi such as A. oryzae, and (2) the dynamic response of the fungus to changes in temperature, which were neglected in the isothermal kinetic experiments.
