- Aim and objectives: To translate the Clinical Trial Nursing Questionnaire (CTNQ) into Swedish and test it for face and content validity as well as internal consistency and reproducibility using test–retest procedures.Introduction/Background: In many countries, as in Sweden, a registered nurse can be involved in research by becoming a clinical research nurse. The clinical research nurse plays a pivotal role in clinical studies as a part of the research team. Scales have been developed and used with the objective to clarify the role of clinical research nurses: one of them is the CTNQ.Methods: A quantitative cross-sectional design with a test–retest procedure was applied to validate the translated questionnaire. By using a snowball sampling method, relevant participants were identified and 49 registered nurses working in the field of research as clinical research nurses answered the questionnaire on two occasions. An expert panel of three clinical research nurses evaluated the questionnaire for face and content validity. The STROBE checklist for observational research has been followed for presenting the research (see File S1).Results: Face and content validity was agreed upon in the expert panel group. Tests for internal consistency of the CTNQ was calculated and showed a high Cronbach's alpha for both the frequency and importance subscales. The test–retest correlation analysis (reproducibility) also revealed a high correlation coefficient for both subscales.Conclusion: The CTNQ-SWE is a valid and robust instrument in a Swedish version. The instrument can be of importance in assessing the role of clinical research nurses in Sweden in future studies.Relevance to clinical practice: Use of the CTNQ-SWE in future research can be of value for clarification and professional development of the clinical research nurse role in Sweden. The further use of the CTNQ in Sweden can be of value in understanding the process where licensed nurses make a transition into becoming a clinical research nurse, and to identify needs for customised education.

- Objectives: To address the associations between emotional, physical and sexual violence, specifically multiple violence victimisation, and sexual ill health and sexual risk behaviours in youth, as well as possible gender differences.Methods: A cross-sectional population-based survey among sexually experienced youth using a questionnaire with validated questions on emotional, physical, and sexual violence victimisation, sociodemographics, health risk behaviours, and sexual ill health and sexual risk behaviours. Proportions, unadjusted/adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated.Results: The participants comprised 1192 female and 1021 male students aged 15 to 22 years. The females had experienced multiple violence (victimisation with two or three types of violence) more often than the males (21% vs. 16%). The associations between multiple violence victimisation and sexual ill health and sexual risk behaviours were consistent for both genders. Experience of/involvement in pregnancy yielded adjusted ORs of 2.4 (95% CI 1.5-3.7) for females and 2.1 (95% CI 1.3-3.4) for males, and early age at first intercourse 2.2 (95% CI 1.6-3.1) for females and 1.9 (95% CI 1.2-3.0) for males. No significantly raised adjusted ORs were found for non-use of contraceptives in young men or young women, or for chlamydia infection in young men.Conclusions: Several types of sexual ill health and sexual risk behaviours are strongly associated with multiple violence victimisation in both genders. This should be taken into consideration when counselling young people and addressing their sexual and reproductive health.

- In this study we have investigated why diameters of tree stems, which are approximately cylindrical, are often overestimated by mobile laser scanning. This paper analyzes the physical processes when using ground-based laser scanning that may contribute to a bias when estimating cylinder diameters using circle-fit methods. A laser scanner simulator was implemented and used to evaluate various properties, such as distance, cylinder diameter, and beam width of a laser scanner-cylinder system to find critical conditions. The simulation results suggest that a positive bias of the diameter estimation is expected. Furthermore, the bias follows a quadratic function of one parameter - the relative footprint, i.e., the fraction of the cylinder width illuminated by the laser beam. The quadratic signature opens up a possibility to construct a compensation model for the bias.
