Varimax Rotation (varimax + rotation)
Selected AbstractsA novel scale for measuring mixed states in bipolar disorderCLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 6 2009Jonathan Cavanagh Abstract Objectives: Conventional descriptions of bipolar disorder tend to treat the mixed state as something of an afterthought. There is no scale that specifically measures the phenomena of the mixed state. This study aimed to test a novel scale for mixed state in a clinical and community population of bipolar patients. Methods: The scale included clinically relevant symptoms of both mania and depression in a bivariate scale. Recovered respondents were asked to recall their last manic episode. The scale allowed endorsement of one or more of the manic and depressive symptoms. Internal consistency analyses were carried out using Cronbach alpha. Factor analysis was carried out using a standard Principal Components Analysis followed by Varimax Rotation. A confirmatory factor analytic method was used to validate the scale structure in a representative clinical sample. Results: The reliability analysis gave a Cronbach alpha value of 0.950, with a range of corrected-item-total-scale correlations from 0.546 (weight change) to 0.830 (mood). The factor analysis revealed a two-factor solution for the manic and depressed items which accounted for 61.2% of the variance in the data. Factor 1 represented physical activity, verbal activity, thought processes and mood. Factor 2 represented eating habits, weight change, passage of time and pain sensitivity. Conclusions: This novel scale appears to capture the key features of mixed states. The two-factor solution fits well with previous models of bipolar disorder and concurs with the view that mixed states may be more than the sum of their parts. Copyright © 2009 John Wiley & Sons, Ltd. Key Practitioner Message: There is no clinical scale that specifically measures the phenomena of the bipolar mixed state. This new scale includes clinically relevant symptoms of both mania and depression in a bivariate scale. The scale appears to capture key features of the mixed state and endorses the view that mixed states may be more than the sum of their parts. [source] The Forensic Inpatient Observation Scale (FIOS): development, reliability and validityCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 3 2001Irma G.H. Timmerman Introduction Re-offending, as a measure of success in forensic psychiatry, gives no information about other behaviours that may have changed. The development of the Forensic Inpatient Observation Scale (FIOS), an observation instrument to assess the non-offending functioning of forensic patients, is described. Study 1 In the first study the development of the initial item pool of the FIOS is described. This resulted in an instrument consisting of 78 items and seven scales. The internal reliability of the scales ranged from 0.78 to 0.91. The inter-rater reliability of the scales varied from 0.50 to 0.85 and the test,retest reliability over a period of three weeks was high for most scales, ranging from 0.74 to 0.89. Study 2 In the second study the FIOS was developed further in another sample of forensic patients. This time exploratory factor analysis with Varimax rotation and post hoc reliability analysis were applied to determine the factor structure among the items. This resulted in an item pool of 35 items, among which six factors could be distinguished that closely resemble the factor structure of the FIOS in study one: (1) self-care, (2) social behaviour, (3) oppositional behaviour, (4) insight offence/ problems, (5) verbal skills and (6) distress. Most items have high loadings on the factor they are assigned; 29 items have a loading of 0.60 or higher. The internal consistency of the scales ranges from 0.73 to 0.91 and the scales appear to be measuring independent constructs. Twenty-five out of the 35 items have an inter-rater correspondence of 90% or higher and 30 out of 35 items have an inter-rater correspondence of 87.5% or higher. The inter-rater reliability on the scale level, however, was somewhat less satisfying with correlations ranging from 0.50 to 0.69. Discussion It is argued that training the observers on a more regular basis will improve the inter-rater reliability. There is some evidence for the convergent validity of the FIOS. The FIOS has some advantages over existing inpatient scales in that it is developed specifically for forensic patients, it does not particularly focus on axis 1 symptoms but includes oppositional behaviour and attitudes to offending.

[source] Interpreting variability in global SST data using independent component analysis and principal component analysisINTERNATIONAL JOURNAL OF CLIMATOLOGY, Issue 3 2010Seth Westra Abstract Component extraction techniques are used widely in the analysis and interpretation of high-dimensional climate datasets such as global sea surface temperatures (SSTs). Principal component analysis (PCA), a frequently used component extraction technique, provides an orthogonal representation of the multivariate dataset and maximizes the variance explained by successive components. A disadvantage of PCA, however, is that the interpretability of the second and higher components may be limited. For this reason, a Varimax rotation is often applied to the PCA solution to enhance the interpretability of the components by maximizing a simple structure. An alternative rotational approach is known as independent component analysis (ICA), which finds a set of underlying ,source signals' which drive the multivariate ,mixed' dataset. Here we compare the capacity of PCA, the Varimax rotation and ICA in explaining climate variability present in globally distributed SST anomaly (SSTA) data. We find that phenomena which are global in extent, such as the global warming trend and the El Niño-Southern Oscillation (ENSO), are well represented using PCA. In contrast, the Varimax rotation provides distinct advantages in interpreting more localized phenomena such as variability in the tropical Atlantic. Finally, our analysis suggests that the interpretability of independent components (ICs) appears to be low. This does not diminish the statistical advantages of deriving components that are mutually independent, with potential applications ranging from synthetically generating multivariate datasets, developing statistical forecasts, and reconstructing spatial datasets from patchy observations at multiple point locations.

Oparah lecturer ABSTRACT Objective To assess patients' satisfaction with pharmaceutical services using an"ideal referent" model, and to further explore the validity of an existing patient satisfaction instrument. Method A cross-sectional survey was conducted with a sample of 500 outpatients recruited consecutively at the University of Benin teaching hospital, Nigeria. A self-completion questionnaire that employed a Likert-type scale was used. Data were used to calculate scores on a scale that ranged from 20 to 100, with an assumed midpoint of 60. Descriptive statistics on the sample characteristics and questionnaire items were computed including means, standard deviations and frequency distributions. Varimax rotation with Kaiser normalisation was employed in principal factor analysis. Student's t -test and one-way ANOVA were used for inferential statistics. Key findings The instrument reliability was determined to be 0.9641 and was comparable to the reference study. Nearly half of the patients (46%) rated the amount of time the pharmacist offered to spend with them as poor. About one-third rated promptness of prescription service as poor. Only 49% felt satisfied with the pharmaceutical services. Overall, pharmacy services received a satisfaction rating of 56.04±24.49, below the midpoint. Perceived satisfaction was significantly higher in "friendly explanation" than in "managing therapy" (t=3.916; P<0.0001). Conclusion The study provides evidence that patients experience low satisfaction with current pharmaceutical services at the study hospital. The sociodemographic characteristics of patients were not associated with their level of satisfaction. We further confirm the validity of the patient satisfaction questionnaire in a Nigerian practice setting. [source] PROFESSION AND SOCIETY: Recovered Medical Error InventoryJOURNAL OF NURSING SCHOLARSHIP, Issue 3 2010DNSc, Patricia C. Dykes RN Abstract Purpose: To describe the development and psychometric testing of the Recovered Medical Error Inventory (RMEI). Design and Methods: Content analysis of structured interviews with expert critical care registered nurses (CCRNs) was used to empirically derive a 25-item RMEI. The RMEI was pilot tested with 345 CCRNs. The data set was randomly divided to use the first half for reliability testing and the second half for validation. A principal components analysis with Varimax rotation was conducted. Cronbach's alpha values were examined. A t test and Pearson correlation were used to compare scores of the two samples. Findings: The RMEI consists of 25 items and two subscales. Evidence for initial reliability includes a total scale alpha of .9 and subscale alpha coefficients of .88 (mistake) and .75 (poor judgment). Conclusions: The RMEI subscales have satisfactory internal consistency reliability and evidence for construct validity. Additional testing is warranted. Clinical Relevance: A tool to measure CCRNs' experiences with recovering medical errors allows quantification of nurse surveillance in promoting safe care and preventing unreimbursed hospital costs for treating nosocomial events. [source] Validation of the Professional Practice Environment Scale in Australian General PracticeJOURNAL OF NURSING SCHOLARSHIP, Issue 2 2010BN(Hons), Elizabeth J. Halcomb RN, FRCNA Abstract Purpose: To validate the Professional Practice Environment Scale (PPE) in Australian general practice. Methods: The PPE was modified slightly for appropriateness for the practice setting and administered to a sample of 342 Australian general practice nurses via an online survey tool. The factor structure of the 38-item PPE was examined using principal components analysis with Varimax rotation. Findings: An eight-factor solution accounted for 71.6% of the variance. Low factor loading (<0.3) or cross-component loadings were detected in eight items. A comparison of Cronbach's alpha values demonstrated little change in the deletion of eight items from four of the eight related components. Conclusions: Findings demonstrated that a 30-item version of the PPE was reliable and valid for use to assess the professional practice environment of nurses working in Australian general practice. Clinical Relevance: A tool to measure the professional practice environment in general practice is important as it will assist in monitoring the impact of the work environment on the recruitment, retention, and satisfaction of nurses in this setting. [source] Quality of life and masticatory function in denture wearersJOURNAL OF ORAL REHABILITATION, Issue 5 2006H. KOSHINO summary, Successful prosthodontic treatments for a patient with removable partial dentures including maxillofacial prostheses hopefully brings about psychological wellbeing as well as improved health. The purpose of this study was to investigate the relationship between quality of life (QOL) and the various aspects of denture function. At first, a questionnaire with a visual analog scale with 16 question items concerning denture and/or eating problems, the present state of health, psychological and physical wellbeing, life satisfaction, and QOL was developed. To discuss the validity and reliability of the questionnaire, 48 outpatients who wore a denture were asked to fill it out. Next, to discuss the difference in QOL of the patient with various kinds of dentures and conditions, 103 outpatients were asked to complete the newly developed questionnaire. The questionnaire which contained four factor areas with eight questions for denture patients was developed by factor analysis with Varimax rotation. The reliability of the QOL scale was confirmed by reliability analysis (Cronbach's ,=0·784). The QOL score of edentulous patients with a complete denture having some trouble chewing was significantly lower than that of other denture patients. It was suggested that the wearing of a denture significantly affected the QOL of elderly persons. [source] The five-factor personality inventory: cross-cultural generalizability across 13 countriesEUROPEAN JOURNAL OF PERSONALITY, Issue 5 2003A. A. Jolijn Hendriks In the present study, we investigated the structural invariance of the Five-Factor Personality Inventory (FFPI) across a variety of cultures. Self-report data sets from ten European and three non-European countries were available, representing the Germanic (Belgium, England, Germany, the Netherlands, USA), Romance (Italy, Spain), and Slavic branches (Croatia, Czech Republic, Slovakia) of the Indo-European languages, as well as the Semito-Hamitic (Israel) and Altaic (Hungary, Japan) language families. Each data set was subjected to principal component analysis, followed by varimax rotation and orthogonal Procrustes rotation to optimal agreement with (i) the Dutch normative structure and (ii) an American large-sample structure. Three criteria (scree test, internal consistency reliabilities of the varimax-rotated components, and parallel analysis) were used to establish the number of factors to be retained for rotation. Clear five-factor structures were found in all samples except in the smallest one (USA, N,=,97). Internal consistency reliabilities of the five components were generally good and high congruence was found between each sample structure and both reference structures. More than 80% of the items were equally stable within each country. Based on the results, an international FFPI reference structure is proposed. This reference structure can facilitate standardized communications about Big Five scores across research programmes. Copyright © 2003 John Wiley & Sons, Ltd. [source] Psychometric characteristics of Cloninger's criteria for personality disorder in a population of French prisonersINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 1 2008Antoine Pelissolo Abstract Cloninger has proposed a new procedure to assess personality disorders on the basis of his model of temperament and character. We explored the psychometric characteristics of this instrument in 560 male prisoners, using factor analyses. Results showed that the 20 items relating to the general personality criteria have acceptable internal consistency and that the three-factor structure of the temperament items used to subtype personality disorder are correctly identified by a maximum likelihood factor analysis model with varimax rotation. Overall, 32% of prisoners had a personality disorder according to this model, and it was possible to subtype 68% of these. This new diagnostic procedure for personality disorder seemed to have satisfactory basic psychometric characteristics but further study is required to explore the concurrent validity and the reliability of this instrument.

[source] The construct validity of the client questionnaire of the Wisconsin Quality of Life Index , a cross-validation studyINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 3 2003Jean Caron Abstract The Wisconsin Quality of Life Index (W-QLI, Becker, Diamond and Sainfort, 1993) consists of eight scales: satisfaction with life domains, occupational activities, symptoms, physical health, social relations/support, finances, psychological wellbeing, and activities of daily living. The W-QLI has been modified to fit the characteristics of the Canadian population, the universal Canadian health system, and community and social services in Canada and the modified form was named CaW-QLI (Diaz, Mercier, Hachey, Caron, and Boyer, 1999). This study will verify the empirical basis of these theoretical dimensions by applying a cross-validation procedure on two samples, most of whose subjects have a serious mental illness. Confirmatory factor analyses and exploratory factor analyses using the principal component extraction technique with varimax rotation were applied. With the exception of the occupational activities domain, the remaining scales were correctly identified by the factor analyses on each sample. The occupational activities scale should be developed by additional items for representing this scale, which is too brief, and two other items should be revised in order to improve the quality of the instrument.

[source] A Multivariate Validation of the Defining Characteristics of FatigueINTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 1 2001Mei Fu MSN PURPOSE. To validate the nursing diagnosis fatigue by providing evidence to identify, confirm, and consolidate the defining characteristics. METHODS. The Revised Piper Fatigue Scale and the Schwartz Measurement of Fatigue scales were used to collect data from four groups of healthy women (N = 182). Data were analyzed by maximum-likelihood factor analysis with varimax rotation, and major and minor defining characteristics were identified and clustered. FINDINGS. The identified defining characteristics tended to group into the dimensions identified in prior fatigue studies. Although the majority of the NANDA defining characteristics were validated, differences were found. CONCLUSIONS. atigue is a multidimensional construct. Replication of the study with a variety of samples from different geographic locations and a variety of patient populations will further cross-validate the defining characteristics of fatigue. PRACTICE IMPLICATIONS. Fatigue is a commonly experienced phenomenon in both health and illness. As the knowledge base about fatigue builds, so will the accuracy of nursing assessments and the effectiveness of nursing interventions. [source] Clinical Learning Environment Inventory: factor analysisJOURNAL OF ADVANCED NURSING, Issue 6 2010Jennifer M. Newton newton j.m., jolly b.c., ockerby c.m. & cross w.m. (2010) Clinical Learning Environment Inventory: factor analysis. Journal of Advanced Nursing,66(6), 1371,1381. Abstract Title.,Clinical Learning Environment Inventory: factor analysis. Aim., This paper is a report of the psychometric testing of the Clinical Learning Environment Inventory. Background., The clinical learning environment is a complex socio-cultural entity that offers a variety of opportunities to engage or disengage in learning. The Clinical Learning Environment Inventory is a self-report instrument consisting of 42 items classified into six scales: personalization, student involvement, task orientation, innovation, satisfaction and individualization. It was developed to examine undergraduate nursing students' perceptions of the learning environment whilst on placement in clinical settings. Method., As a component of a longitudinal project, Bachelor of Nursing students (n = 659) from two campuses of a university in Australia, completed the Clinical Learning Environment Inventory from 2006 to 2008. Principal components analysis using varimax rotation was conducted to explore the factor structure of the inventory. Results., Data for 513 students (77%) were eligible for inclusion. Constraining data to a 6-factor solution explained 51% of the variance. The factors identified were: student-centredness, affordances and engagement, individualization, fostering workplace learning, valuing nurses' work, and innovative and adaptive workplace culture. These factors were reviewed against recent theoretical developments in the literature. Conclusion., The study offers an empirically based and theoretically informed extension of the original Clinical Learning Environment Inventory, which had previously relied on ad hoc clustering of items and the use of internal reliability of its sub-scales. Further research is required to establish the consistency of these new factors. [source] Testing of a measurement model for baccalaureate nursing students' self-evaluation of core competenciesJOURNAL OF ADVANCED NURSING, Issue 11 2009Li-Ling Hsu Abstract Title.,Testing of a measurement model for baccalaureate nursing students' self-evaluation of core competencies. Aim. This paper is a report of a study to test the psychometric properties of the Self-Evaluated Core Competencies Scale for baccalaureate nursing students. Background. Baccalaureate nursing students receive basic nursing education and continue to build competency in practice settings after graduation. Nursing students today face great challenges. Society demands analytic, critical, reflective and transformative attitudes from graduates. It also demands that institutions of higher education take the responsibility to encourage students, through academic work, to acquire knowledge and skills that meet the needs of the modern workplace, which favours highly skilled and qualified workers. Methods. A survey of 802 senior nursing students in their last semester at college or university was conducted in Taiwan in 2007 using the Self-Evaluated Core Competencies Scale. Half of the participants were randomly assigned either to principal components analysis with varimax rotation or confirmatory factor analysis. Results. Principal components analysis revealed two components of core competencies that were named as humanity/responsibility and cognitive/performance. The initial model of confirmatory factor analysis was then converged to an acceptable solution but did not show a good fit; however, the final model of confirmatory factor analysis was converged to an acceptable solution with acceptable fit. The final model has two components, namely humanity/responsibility and cognitive/performance. Both components have four indicators. In addition, six indicators have their correlated measurement errors. Conclusion. Self-Evaluated Core Competencies Scale could be used to assess the core competencies of undergraduate nursing students. In addition, it should be used as a teaching guide to increase students' competencies to ensure quality patient care in hospitals. [source] Attitudes of intensive care nurses towards brain death and organ transplantation: instrument development and testingJOURNAL OF ADVANCED NURSING, Issue 5 2006Jung Ran Kim BN MClinN DipN RN Aims., This paper reports the development and testing of an instrument assessing attitudes of Korean intensive care unit nurses. Background., Reluctance by healthcare professionals to identify brain-dead patients as a potential donor is one reason for a shortfall in transplantable organs in all countries. Organ donation from brain-dead patients is a particularly contentious issue in Korea, following recent legal recognition of brain death within the cultural context of Confucian beliefs. Method., A 38-item instrument was developed from the literature and key informant interviews, and validated by an expert panel and a pilot study. A survey was conducted with Korean intensive care unit nurses (n = 520) from October 2003 to January 2004. Principal component analysis with varimax rotation was used to determine construct validity. Item-to-total correlations and Cronbach's coefficient alpha were used to determine the scale's internal consistency and unidimensionality. Results., The scale demonstrated high internal consistency (alpha = 0·88). Principal component analysis yielded a four-component structure: Discomfort, Enhancing quality of life, Willingness to be a donor and Rewarding experience. Overall, Korean intensive care unit nurses showed positive attitudes towards organ transplantation, despite some mixed feelings. Conclusion., The attitude scale was reliable and valid for this cohort. Areas were identified where professional development may enhance positive attitudes towards organ transplantation from brain-dead donors. Effective education for intensive care unit nurses is necessary to increase the organ donor pool in Korea. Further research could test the instrument with other populations. [source] Disclosure to therapists: What is and is not discussed in psychotherapyJOURNAL OF CLINICAL PSYCHOLOGY, Issue 4 2002Barry A. Farber This study used the 80-item Disclosure to Therapist Inventory,R to investigate the nature of patient disclosure within therapy. Participants (45 men, 102 women) were all currently in therapy. A Principal Components Analyses with varimax rotation yielded nine meaningful factors; mean disclosure scores were lowest for the factors of Sexuality and Procreation and highest for the factors of Negative Affect and Intimacy. Specific items most extensively discussed included characteristics of parents that are disliked, and aspects of one's personality that are disliked or worrisome. No significant differences were found in overall degree of disclosure as a function of patient gender or shame-proneness; disclosure was, however, found to be positively correlated with strength of the therapeutic alliance. © 2002 Wiley Periodicals, Inc.

[source] A new scale to measure family members' perception of community health care services for persons with Huntington diseaseJOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 3 2010Valmi D. Sousa PhD CNS-BC RN Abstract Rationale, aims, and objectives, Huntington disease (HD) is a progressive genetic brain disease leading to disruptive cognitive, behavioural and physical impairments. Persons with the condition and their caregivers need appropriate and accessible health care services to help them manage the disease adequately. The purpose of this study was to evaluate the psychometric properties of a new scale that measures family members' perception of community health care services (CHCS) for persons with HD. Methods, A methodological design was used to examine the initial reliability and dimensionality of the CHCS scale among 245 family members of persons with a diagnosis of HD. Data analysis consisted of computing Cronbach's , coefficients, calculating the 95% confidence interval for , and performing item-analysis and exploratory factor analysis. Results, Reliability of the scale based on Cronbach's , was 0.83. Factor analysis using principal component analysis and varimax rotation suggested that three interpretable factors underlie the scale. Factor 1, HD knowledge, had , = 0.82, eigenvalue of 4.67 and explained 33.42% of the variance; factor 2, HD community resources, had , = 0.62, eigenvalue of 1.68 and explained 12.02% of the variance; factor 3, individualized HD management, had , = 0.77, eigenvalue of 1.45 and explained 10.39% of the variance. Conclusions, Findings from this study provide evidence of both construct validity and internal consistency reliability of the CHCS scale. Further psychometric testing of the scale in other samples of family caregivers of persons with HD is warranted. [source] Psychometric Analysis of the Brisbane Practice Environment Measure (B-PEM)JOURNAL OF NURSING SCHOLARSHIP, Issue 1 2010Anndrea Flint RN, MHSc(HSM) Abstract Purpose: To undertake rigorous psychometric testing of the newly developed contemporary work environment measure (the Brisbane Practice Environment Measure [B-PEM]) using exploratory factor analysis and confirmatory factor analysis. Methods: Content validity of the 33-item measure was established by a panel of experts. Initial testing involved 195 nursing staff using principal component factor analysis with varimax rotation (orthogonal) and Cronbach's alpha coefficients. Confirmatory factor analysis was conducted using data from a further 983 nursing staff. Results: Principal component factor analysis yielded a four-factor solution with eigenvalues greater than 1 that explained 52.53% of the variance. These factors were then verified using confirmatory factor analysis. Goodness-of-fit indices showed an acceptable fit overall with the full model, explaining 21% to 73% of the variance. Deletion of items took place throughout the evolution of the instrument, resulting in a 26-item, four-factor measure called the Brisbane Practice Environment Measure-Tested. Conclusions: The B-PEM has undergone rigorous psychometric testing, providing evidence of internal consistency and goodness-of-fit indices within acceptable ranges. The measure can be utilised as a subscale or total score reflective of a contemporary nursing work environment. Clinical Relevance: An up-to-date instrument to measure practice environment may be useful for nursing leaders to monitor the workplace and to assist in identifying areas for improvement, facilitating greater job satisfaction and retention. [source] Development of a Self-Report Instrument to Measure Patient Safety Attitudes, Skills, and KnowledgeJOURNAL OF NURSING SCHOLARSHIP, Issue 4 2008Rebecca Schnall Purpose: To describe the development and psychometric testing of the Patient Safety Attitudes, Skills and Knowledge Scale (PS-ASK). Methods: Content validity of a 35-item instrument was established by a panel of experts. The instrument was pilot tested on 285 nursing students. Principal components analysis (PCA) with varimax rotation was conducted, and Cronbach's alphas were examined. Paired samples t-tests were used to show responsiveness of the scales pre- and post-patient safety curriculum. Results: The final instrument consists of 26 items and three separate scales: attitudes, skills, and knowledge. The attitudes and skills scales each had a three-factor solution. The knowledge items had a one-factor solution. Both skills and knowledge were significantly increased at Time 2 (p<0.001). Conclusions: The skills and knowledge subscales had satisfactory internal consistency reliability, evidence for construct validity, and responsiveness for use as independent scales in future studies. The attitudes subscale needs further refinement before implementation. Comparison with other measures of patient safety skills (e.g., observation) and knowledge are warranted. Clinical Relevance: A tool to measure clinicians' attitudes, skills, and knowledge about patient safety might be useful to evaluate nurses and other clinicians during educational preparation and in practice. [source] A Behavioral Genetic Analysis of the Relationship Between the Socialization Scale and Self-Reported DelinquencyJOURNAL OF PERSONALITY, Issue 1 2000Jeanette Taylor This investigation examined the genetic (A), and shared (C) and nonshared (E) environmental variance contributions to the relationship of self-reported delinquency (as measured by the "Delinquent Behavior Inventory" [DBI; Gibson, 1967]) to the Socialization (So) scale of the California Psychological Inventory using univariate and bivariate structural equation models. The scales were administered to 222 male (145 monozygotic; 77 dizygotic) and 159 female (107 monozygotic; 52 dizygotic) 16- to 18-year-old same-sex twin pairs. Principal components analysis with varimax rotation revealed three interpretable So factors representing family/home environment, self-concept, and behavioral control. Univariate modeling suggested sex differences in etiological influences associated with individual differences in most scales. The bivariate ACE model fit the data, suggesting that the covariance between the So scale and self-reported delinquency owes in part to shared etiological factors. [source] Measuring fatigue among women with Sjögren's syndrome or rheumatoid arthritis: A comparison of the Profile of Fatigue (ProF) and the Multidimensional Fatigue Inventory (MFI)MUSCULOSKELETAL CARE, Issue 1 2008C. E. Goodchild BSc MSc Abstract Background:,Fatigue is common in both Sjögren's syndrome (SS) and rheumatoid arthritis (RA) and can restrict functioning. Aims:,We tested the convergent validity of the Profile of Fatigue (ProF) using the Multidimensional Fatigue Inventory (MFI) in SS and RA. Methods:,The 16-item ProF and the 20-item MFI were completed by 82 White-British women aged 35,79 years (mean 60.4 years). Thirty-four had been diagnosed with SS for a mean of 7.0 years and 48 had been diagnosed with RA for a mean of 14.5 years. The ProF measures four somatic facets of fatigue and two mental facets; the MFI contains one mental and four somatic facets. The structures of the items from both measures were tested by principal component factor analysis using varimax rotation. Results:,No significant differences in fatigue were found between the women with SS or RA. Five factors explained a total of 76% of the variance of the MFI; six factors explained 94% of the variance of the ProF. Mental fatigue items from both questionnaires loaded onto separate factors from somatic fatigue items; the two original facets of mental fatigue in the ProF were replicated. The four somatic fatigue facets of the ProF were generally replicated but the somatic facets of the MFI did not replicate as clearly. Equivalent facets correlated well between the two questionnaires (r , 0.65). Conclusions:,Both the ProF and the MFI distinguish between somatic and mental fatigue in SS and RA but the ProF appears better at resolving somatic facets of fatigue.

[source] Countertransference to psychiatric patients in a clinical setting: Development of the Feeling Checklist,Japanese versionPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 6 2006FUJIKA KATSUKI rn Abstract, Countertransference is an important dimension of the therapeutic alliance between care providers and patients. The Feeling Checklist (FC) is a self-report questionnaire for the assessment of countertransference by hospital staff toward patients. The FC was translated from English into Japanese and its factor structure, reliability, and validity in the Japanese version (FC-J) were examined. A total of 281 Japanese psychiatric nurses were tested with the FC-J. All nurses were primarily involved in provision of psychiatric care. Principal-component factor analysis with varimax rotation was performed to identify the potential components of the FC-J. In a factor analysis of the FC-J, seven factors were extracted. The five subscales that were determined and labeled included Reject, Distance, Helpfulness, Closeness, and Involvement, which collectively accounted for 56.0% of the variance. Cronbach's ,, a measure of internal consistency, for individual subscales was 0.833 for Reject, 0.763 for Distance, 0.768 for Helpfulness, 0.617 for Closeness, and 0.663 for Involvement. Notably, there was a significant correlation between the FC-J and the Nurse Attitude Scale (P < 0.0001). Moreover, one-way anova was performed with each FC-J subscale to examine differences among psychiatric diagnoses in the study sample. A significant difference was found for Involvement (P < 0.001), with the total score on Involvement being the highest in the personality disorder group. These results are considered to verify the reliability and validity of the FC-J as a scale to measure countertransference among Japanese care providers. The use of this scale allows individual care providers to recognize and be cognizant of their own countertransference objectively and thereby contributes to improve the relationship between patients and care providers. [source] Self-efficacy for coping with cancer: revision of the Cancer Behavior Inventory (version 2.0)PSYCHO-ONCOLOGY, Issue 3 2001Thomas V. Merluzzi The Cancer Behavior Inventory (CBI), a measure of self-efficacy for coping with cancer, was revised by adding a new stress management scale and reducing its length from 43 to 33 items. The 33-item CBI was administered to 280 cancer patients. A principal factors analysis with varimax rotation yielded the hypothesized seven factors (,s in parentheses): (1) maintenance of activity and independence (,=0.86), (2) seeking and understanding medical information (,=0.88), (3) stress management (,=0.86), (4) coping with treatment-related side-effects (,=0.82), (5) accepting cancer/maintaining positive attitude (,=0.86), (6) affective regulation (,=0.81), and (7) seeking support (,=0.80). The , for the entire CBI was 0.94, the test-retest (1 week) reliability coefficient was 0.74, and correlations with measures of quality of life and coping supported its validity. The CBI may be useful to researchers and clinicians and can be integrated into a self-regulation model of coping. Copyright © 2001 John Wiley & Sons, Ltd. [source] Reliability and validity of the sexual pressure scale,RESEARCH IN NURSING & HEALTH, Issue 4 2006Rachel Jones Abstract The purpose of this study was to develop the Sexual Pressure Scale (SPS) as a valid and reliable measure of gender stereotypical expectations to engage in sexual behavior. Data were collected using audio computer-assisted self-interview in 306 urban women, aged 18 to 29. Exploratory principal components analysis with varimax rotation yielded 19 items consisting of five factors: Condom Fear, Sexual Coercion, Women's Sex Role, Men Expect Sex, and Show Trust, accounting for 62% of the variance. Divergent and convergent validity were supported, respectively, by negative relationships of SPS factors with dyadic trust and positive relationships with sexual victimization and sexual risk behavior. Alpha reliability was .81; factor reliabilities ranged from .63 to .82. A valid assessment of sexual pressure can suggest the extent to which stereotypical gender expectations structure women's freedom to explore partner and condom use choices. © 2006 Wiley Periodicals, Inc.
