Cardiac anxiety in people with and without coronary atherosclerosis,

DEPRESSION AND ANXIETY, Issue 10 2008
Craig D. Marker Ph.D.
Abstract Many studies have shown that cardiac anxiety when occurring in the absence of coronary artery disease is common and quite costly. The Cardiac Anxiety Questionnaire (CAQ) is an 18-item self-report measure that assesses anxiety related to cardiac symptoms. To better understand the construct of cardiac anxiety, a factor analysis was conducted on CAQ data from 658 individuals who were self or physician-referred for electron beam tomographic screening to determine whether clinically significant coronary atherosclerosis was present. A four-factor solution was judged to provide the best fit with the results reflecting the following factor composition: heart-focused attention, avoidance of activities that bring on symptoms, worry or fear regarding symptoms, and reassurance-seeking. Factorial invariance across groups was also assessed to determine whether the factor structure of the CAQ was similar in individuals with and without clear evidence of coronary atherosclerosis. The factor structure of the CAQ did not differ between the two groups. However, the group without coronary atherosclerosis had significantly higher mean scores on their attention and worry/fear factors suggesting that people without a diagnosed cardiac condition pay more attention to and worry more about their cardiac-related symptoms than those people who have coronary atherosclerosis.

Dental beliefs: factor structure of the revised dental beliefs survey in a group of regular dental patients

EUROPEAN JOURNAL OF ORAL SCIENCES, Issue 6 2009
Kajsa H. Abrahamsson
The aim of this study was to investigate the factor structure of the revised dental beliefs survey (DBS-R) in a group of regular dental patients. The study group consisted of 278 patients (mean age 54 yr), 61% of whom were women. The DBS-R item mean value was 1.6. Principal component analysis (PCA) and confirmatory factor analysis (CFA) were performed. The initial PCA among the 28 DBS-R items showed four factors with eigenvalues of > 1 explaining 67% of the total variance. Five different CFA models were tested. The final model revealed a four-factor solution with one second-order factor (i.e. a hierarchical CFA). Thus, the latent second-order variable, ,dental beliefs', explains the variance from all DBS-R items through the four first-order factors labeled ,ethics', ,belittlement', ,communication and empathy', and ,control and anxiety'. The results suggest a somewhat different factor structure of DBS-R than previously reported for dental-fear patients. Hence, the underlying factor structure of the DBS-R may differ between different patient groups. The results point towards the use of the original 28-item DBS-R and interpreting the scale as measuring an overall construct of ,dental beliefs' and thus patients' attitudes and feelings related to dentists and dentistry.

Psychometric evaluation of the body investment scale for use with adolescents

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 3 2010
Augustine Osman
Abstract We conducted two studies to examine the psychometric properties of the Body Investment Scale (BIS; Orbach & Mikulincer, 1998) in U.S. adolescent samples. The BIS was designed to assess bodily experiences that are associated with suicide-related behaviors. In Study 1, confirmatory factor analysis (CFA) with data from a combined sample of 204 high school adolescents (83 boys, 121 girls) and 197 psychiatric inpatient (101 boys, 96 girls) adolescents provided moderate support for the oblique four-factor solution: Body Feelings (,=.86, 95% CI=.83,.89), Body Touch (,=.71, 95% CI=.65,.76), Body Care (,=.78, 95% CI=.71,.81), and Body Protection (,=.78, 95% CI=.73,.82); robust comparative fit index=.88 and the robust Tucker Lewis Index=.83. The second-order factor model also provided moderate fit to the data. In Study 2, results of the CFA with data from adolescent psychiatric inpatients (N=205; 101 boys, 104 girls) provided additional support for the four-factor solution. In addition, results of the receiver operating characteristic and logistic regression analyses showed that scores on the Body Feelings and Body Protection scales were most useful in differentiating the responses of suicidal and nonsuicidal adolescents, all Cohen's d values >.30. The study also examined associations between scores on the BIS scales and the validation self-report measures of hopelessness, suicide-related behavior, and reasons for living. © 2009 Wiley Periodicals, Inc.

Psychometric Analysis of the Brisbane Practice Environment Measure (B-PEM)

JOURNAL OF NURSING SCHOLARSHIP, Issue 1 2010
Anndrea 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.
