- The morphological appearance of the vastus lateralis (VL) muscle from high-level power-lifters on long-term anabolic steroid supplementation (PAS) and power-lifters never taking anabolic steroids (P) was compared. The effects of long- and short-term supplementation were compared. Enzyme-immunohistochemical investigations were performed to assess muscle fiber type composition, fiber area, number of myonuclei per fiber, internal myonuclei, myonuclear domains and proportion of satellite cells. The PAS group had larger type I, IIA, IIAB and IIC fiber areas (p<0.05). The number of myonuclei/fiber and the proportion of central nuclei were significantly higher in the PAS group (p<0.05). Similar results were seen in the trapezius muscle (T) but additionally, in T the proportion of fibers expressing developmental myosin isoforms was higher in the PAS group compared to the P group. Further, in VL, the PAS group had significantly larger nuclear domains in fibers containing > or = 5 myonuclei. The results of AS on VL morphology in this study were similar to previously reported short-term effects of AS on VL. The initial effects from AS appear to be maintained for several years.

Utvärdering av metoder mot mobbning
- 2011
-
Rapport (övrigt vetenskapligt)abstract
- Denna utvärdering ger besked om insatser och arbetssätt som effektivt förebygger och åtgärdar mobbning. Utvärderingen är unik genom att den omfattar stora mängder data, både kvalitativa och kvantitativa från 39 skolor, att enskilda individers utsatthet följs upp vid tre tillfällen och att den omfattar flera program samtidigt.Resultaten visar bland annat att olika insatser har olika effekt för pojkar och flickor samt olika effekt beroende på om mobbningen är social eller fysisk. Den visar också att ingen enskild insats har dramatiskt positiva effekter. För att en skola ska lyckas förebygga och åtgärda mobbning krävs ett systematiskt arbete och en kombination av insatser. Åtta namngivna program som används mot mobbning har ingått i utvärderingen: Farstametoden, Friends, Lions Quest, Olweusprogrammet, SET – Social och emotionell träning, Skolkomet, Skolmedling samt Stegvis. I utvärderingens fristående metodfördjupning Utvärdering av metoder mot mobbning. Metodappendix och bilagor till rapport 353, (endast publicerad som pdf ) redovisar forskarna utförligt utvärderingens design och redogör för tillvägagångssättet vid datainsamling och analys.

Evaluation of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) in persons with heart disease : A pilot study
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Background: As part of preparation for a Swedish multicentre study, exploring sexual and married life in patients with myocardial infarction and their partners, a Swedish validated instrument was required.Aims: The aim of this pilot study was to evaluate the validity and reliability of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) among persons with a heart disease.Methods: A convenience sample of 79 persons (47 men and 32 women) living with a heart disease was recruited from the members of the National Association of Heart and Lung Patients. They completed a Swedish version of the WSFQ on two occasions.Results: Two separate factor analyses each revealed a two-factor structure on both occasions: “Sexual appetite” and “Sexual expectations” with gender-neutral questions and “Sexual sensitiveness” and “Sexual ability” with gender-specific questions. Cronbach's alpha coefficients ranged from 0.48 to 0.86 and test–retest values for all but one question exceeded 0.70.Conclusions: The Swedish version of the WSFQ showed good validity and stability and acceptable internal homogeneity. Extended evaluations of the questionnaire are recommended.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: There is a need for a short and easily administered scale, in the Swedish language, for assessing partner relationships in the health care of persons with cardiac disease. PURPOSE: To establish the reliability and validity of the Swedish version of the Relationship Assessment Scale (RAS). DESIGN: The present pilot study has a methodological design. FINDINGS: Content validity has been tested for relevance, clarity and readability. The scale was tested for construct validity with explorative factor analysis. The reliability was tested by internal consistency and test-retest analysis. The result showed a two-factor solution, which does not correspond to the original proposed one-factor solution. The factor analyses revealed two quite distinct factors of RAS, labelled "Relationship built on expectations and satisfaction of needs" and "Relationship built on love and devotion". CONCLUSIONS: The scale has satisfactory psychometric properties in terms of content validity, construct validity, homogeneity and stability in a population of persons with cardiac disease. Wider evaluations of the RAS for other populations and settings are recommended.
