The Melbourne Decision-Making Questionnaire (MDMQ) is an attempt to capture and measure coping strategies that people use. The instrument had not previously been translated into Swedish. The aim of this study was to evaluate validity and reliability of the Swedish version of the MDMQ.
A Swedish translation was performed and back-translated. A group of five pilot readers evaluated content validity. The translated questionnaire was tested among 735 patients, healthcare workers, healthcare students and teachers. A parallel analysis (PA), exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed.
An initial EFA with a four-factor solution showed a low concordance with the original 22-item four-factor model with a very low Cronbach's alpha in one of the dimensions. However, a second EFA with a three-factor solution showed a good model fit for the Swedish translation of the Melbourne Decision-Making Questionnaire (MDMQ-S) with a satisfactory Cronbach's alpha. A CFA showed a goodness of fit after deleting six items.
After testing the MDMQ-S, we found support for validity and reliability of the instrument. We found the 16-item version of MDMQ-S to be satisfactory concerning the subscales vigilance, procrastination and buck-passing. However, we found no support that the hypervigilance dimension could be measured by the MDMQ-S.
Digital Elevation Models (DEMs) play a prominent role in glaciological studies for the mass balance of glaciers and ice sheets. By providing a time snapshot of glacier geometry, DEMs are crucial for most glacier evolution modelling studies, but are also important for cryospheric modelling in general. We present a historical medium-resolution DEM and orthophotographs that consistently cover the entire surroundings and margins of the Greenland Ice Sheet 1978-1987. About 3,500 aerial photographs of Greenland are combined with field surveyed geodetic ground control to produce a 25?m gridded DEM and a 2?m black-and-white digital orthophotograph. Supporting data consist of a reliability mask and a photo footprint coverage with recording dates. Through one internal and two external validation tests, this DEM shows an accuracy better than 10?m horizontally and 6?m vertically while the precision is better than 4?m. This dataset proved successful for topographical mapping and geodetic mass balance. Other uses include control and calibration of remotely sensed data such as imagery or InSAR velocity maps.

Health literacy (HL) is an important determinant for health and a valuable health indicator within public health. As such, it is a significant outcome variable of health promotion efforts. Valid and reliable instruments are needed to evaluate health promotion interventions and to assess levels of HL in a population. One of the few measurements of communicative and critical HL is the Japanese Communicative and Critical Health Literacy scale (C & C HL scale). To make it possible to use this instrument in Sweden, the C & C HL scale was translated into Swedish and different aspects of validity, including test-retest reliability, of the translated version were tested.
After translation and back-translation, The Swedish C & C HL scale was tested for content validity and test-retest reliability. Data were collected from a committee consisting of public health experts and bilingual people, and from a test group of 35 persons.
The Swedish C & C HL scale was understandable and showed evidence of content validity. The test-retest confirmed that it was stable over time, percentage agreements for the items ranging from 66% to 89% (M = 74%).
The Swedish C & C HL scale is equivalent to the Japanese C & C HL scale in terms of language and content. The items cover the major aspects of communicative and critical HL and are understandable and stable over time, i.e., reliable.
The field of sleep disorders medicine is facing enormous challenges as it strives to gain recognition from the medical profession, the public and government. One of these challenges is to ensure that limited resources for diagnosis are used wisely. The authors argue that the standards for polysomnography developed by the Canadian Sleep Society and the Canadian Thoracic Society (see pages 1673 to 1678 of this issue) will go a long way toward ensuring that this expensive resource is used prudently. In the mean-time, more research is needed to determine valid measures of the impact of sleep disorders and to establish the reliability of different diagnostic methods.

Assessing pain in the intensive care unit (ICU) is challenging. Due to intubation and sedation, communication can be limited. International guidelines recommend assessing pain with instruments based on behavioral parameters when critically ill patients are unable to self-report their pain level. One of the recommended instruments, the Behavioral Pain Scale (BPS), has shown good validity and reliability in international studies. The aim of this study was to translate and adapt the BPS for critically ill intubated and non-intubated patients in a Swedish ICU context and to assess inter-rater reliability and discriminant validity.
The BPS (both for intubated and non-intubated patients) was translated and adapted into Swedish using a translation method consisting of ten steps. The Swedish version was then tested for inter-rater reliability and discriminant validity on 20 critically ill patients (10 intubated and 10 non-intubated) before and directly after a potentially painful procedure (repositioning).
The Swedish version of the BPS showed inter-rater reliability with a percentage agreement of 85% when tested on a sample of critically ill patients. The instrument also showed discriminant validity between assessments at rest and after repositioning.
Results of the Swedish version of the BPS support its use in critically ill patients who cannot self-report their pain level. Still, additional studies are needed to further explore its reliability and validity in the Swedish ICU context.

This study measured the validity of work histories obtained by interview with 84 female workers and examined specific factors which influence such validity. This is the first validation of work histories collected by interviews with women. The validity of each interview was assessed over a period of 29 years, from 1955 to 1983. The information provided by the worker was compared annually to job information registered in public and union records. On the average, interviews yielded the correct information (either employer's name or nonworking year) for 81% of the person years of these subjects. However, there was a time effect; the average validity score for recent employment (1972-1983) was 89%, while that for employment in the more distant past (1955-1971) was 74%. Furthermore, workers who had fewer jobs, had longer durations of employment, and were non-French speaking had higher validity scores. Most of these findings are consistent with previous studies conducted among male respondents.
