Selected AbstractsThe Accuracy and Completeness of Data Collected by Prospective and Retrospective MethodsACADEMIC EMERGENCY MEDICINE, Issue 9 2005J. Tobias Nagurney MD Abstract Objectives: To describe and test a model that compares the accuracy of data gathered prospectively versus retrospectively among adult emergency department patients admitted with chest pain. Methods: The authors developed a model of information flow from subject to medical record to the clinical study case report form, based on a literature review. To test this model, a bidirectional (prospective and retrospective) study was conducted, enrolling all eligible adult patients who were admitted with a chief complaint of chest pain. The authors interviewed patients in the emergency department to determine their chest pain history and established a prospective database; this was considered the criterion standard. Then, patient medical records were reviewed to determine the accuracy and completeness of the information available through a retrospective medical record review. Results: The model described applies the concepts of reliability and validity to information passed on by the study subject, the clinician, and the medical record abstractor. This study was comprised of 104 subjects, of which 63% were men and the median age was 63 years. Subjects were uncertain of responses for 0,8% of questions and responded differently upon reinterview for subsets of questions 0,30% of the time. The sensitivity of the medical record for risk factors for coronary artery disease was 0.77 to 0.93. Among the 88 subjects (85%) who indicated that their chest pain was substernal or left chest, the medical record described this location in 44%. Timing of the chest pain was the most difficult item to accurately capture from the medical record. Conclusions: Information obtained retrospectively from the abstraction of medical records is measurably less accurate than information obtained prospectively from research subjects. For certain items, more than half of the information is not available. This loss of information is related to the data types included in the study and by the assumptions that a researcher performing a retrospective study makes about implied versus explicitly stated responses. A model of information flow that incorporates the concepts of reliability and validity can be used to measure some of the loss of information that occurs at each step along the way from subject to clinician to medical record abstractor. [source] Differences in depression symptoms in patients with Alzheimer's and Parkinson's diseases: evidence from the 15-item Geriatric Depression Scale (GDS-15)INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 10 2007Daniel Weintraub Abstract Objective Depression occurs frequently in patients with both Alzheimer's disease (AD) and Parkinson's disease (PD), but there has been little comparison of depression symptoms in the two populations. Method The 15-item Geriatric Depression Scale (GDS-15) was administered as a depression screening instrument to 232,AD patients and 266,PD specialty care patients with at most mild dementia. Logistic regression models were used to determine disease-specific associations with individual GDS-15 items, and factor analysis was used to assess GDS-15 factor structure in the two populations. Results Controlling for total GDS-15 score and other covariates, AD patients reported more dissatisfaction with life (p,=,0.03) and memory problems (p,<,0.001), while PD patients reported more fearfulness (p,=,0.01), helplessness (p,<,0.01), a preference to stay at home (p,=,0.02), and diminished energy (p,<,0.01). Three factors were generated in PD (explaining 55% of the total variance) and five in AD (explaining 59% of the total variance), and the two main factors generated in both populations related primarily to unhappiness and negative thoughts. Conclusions The factor structure of the GDS-15 is similar in AD and PD patients with at most mild stage dementia, but between-group differences on 6 of the GDS-15 items suggests the non-specificity of certain items in the two populations.

[source] The mental adjustment to cancer (MAC) scale: French replication and assessment of positive and negative adjustment dimensionsPSYCHO-ONCOLOGY, Issue 1 2003Sandrine Cayrou The Mental Adjustment to Cancer (MAC) scale was validated on a heterogeneous French sample of 317 cancer patients. Internal consistency was satisfactory for the original subscales (, coefficients=0.62,0.80), except for the Fatalism subscale (,=0.40). The intercorrelations of the subscales and the correlations between the subscales and Anxiety and Depression criteria were congruent with the values reported in the literature. Multidimensional Scaling revealed three positive and three negative subsets of items revealing adjustment to cancer. Congeneric factor analysis of the subsets was performed with LISREL 8.3 and only three of them (after discarding certain items) were retained: Fighting Spirit (FS) Hopelessness/Helplessness (HH) and Anxious Preoccupation (AP). A confirmatory hierarchical factor analysis on the 21 items included showed that FS measured positive adjustment to cancer and HH and AP measured negative adjustment. A differential adjustment hypothesis was proposed in order to explain the stability and instability of the measures of the diverse constructs. The three revised subscales showed the same validity pattern as the corresponding original scales, but the magnitude of the correlations was considerably improved with respect to the original subscales. The practical and the theoretical importance of FS, HH and AP are emphasized. Copyright © 2003 John Wiley & Sons, Ltd. [source] Choices Within Collective Labour Agreements à la Carte in the NetherlandsBRITISH JOURNAL OF INDUSTRIAL RELATIONS, Issue 1 2006Lei Delsen In recent years European employers, unions and governments have developed initiatives that offer employees the right to exchange certain items within an agreed package of employment conditions. So far, the available evidence on the use of such ,cafeteria systems' is largely based on survey data rather than on actual choices. We analyse the actual choices made by the employees of Radboud University Nijmegen in the years 2002,2004. The results cast doubt on the efficiency and the effectiveness of employee choices within collective agreements, contradict the unions' push for working time reduction and question wage moderation and policies on work,life balance. [source] Stepfather involvement in social interventions made by youth protection services in stepfamiliesCHILD & FAMILY SOCIAL WORK, Issue 3 2007Claudine Parent ABSTRACT Despite efforts made by management and caseworkers to promote active parental participation in the protective context, fathers or other male figures are often brushed aside from intervention. This paper presents the results of qualitative research on methods used by youth protection caseworkers (n = 22) working with stepfather families. The main objective is to identify items that encourage or discourage stepfather involvement in psychosocial interventions. Results showed that certain items do not apply solely to stepfathers, but influence youth protection caseworker decision-making from a broader perspective. Particular characteristics associated with being a stepfather significantly influence involvement practices espoused by caseworkers, notably the absence of legal status and biological connection with the mother's children.
