Objective:
To assess maladaptive beliefs about low back pain (LBP), valid and reliable measurement tools are required. Although some tools exist to assess them, the Low Back Pain-related Beliefs Screening Tool (LBP-BST) was developed in order to explore all different categories of misbeliefs in individuals chronic low back pain (CLBP). This study aimed to evaluate the main psychometric properties of both the short and long versions of the revised LBPBSTv2.
Methods:
A total of 108 patients with CLBP completed the LBP-BSTv2 to assess its potential floor/ceiling effects, internal consistency, and construct validity. The latter was evaluated by comparing scores with the Back Beliefs Questionnaire (BBQ). Test-retest reliability was assessed in 47 of the participants one week later.
Results:
No floor or ceiling effects were observed. The short and long versions of the LBPBSTv2 showed strong construct validity, with significant correlations with BBQ scores. Internal consistency was acceptable to good (Cronbach’s alpha: 0.77–0.84), and test-retest reliability was high (intraclass correlation coefficient: 0.76–0.81).
Conclusion
The LBP-BSTv2 is a valid and reliable tool for assessing maladaptive beliefs in patients with CLBP. Its integration into clinical practice could help healthcare professionals identify and address unhelpful beliefs that may hinder rehabilitation. Further research is needed to confirm its usefulness in tracking changes over time and guiding individualized interventions and to study other psychometric properties such as responsiveness.

Purpose:
Rabies is a fatal but preventable disease with proper pre-exposure anti-rabies vaccination (ARV). Dogs, as household pets and strays, are the reservoir and vector of the disease, and dog bites have been associated with human rabies cases in Sri Lanka over the past few years. However, other susceptible species having frequent contact with humans may be a source of infection. One such species is sheep and immunity following ARV has never been tested in sheep reared in Sri Lanka.
Materials and Methods:
We have tested serum samples from sheep reared in the Animal Centre, Medical Research Institute of Sri Lanka for the presence of anti-rabies antibodies following ARV. Sheep serum samples were tested with Bio-Pro Rabies enzyme-linked immunosorbent assay (ELISA) antibody kits used for the first time in Sri Lanka and our results were verified by a seroneutralization method on cells (fluorescent antibody virus neutralization, FAVN test) currently recommended by World Organization for Animal Health and World Health Organization.
Results:
Sheep received annual ARV and maintained high neutralizing antibody titers in their serum. No maternal antibodies were detected in lamb around 6 months of age. Agreement between the ELISA and FAVN test, i.e., coefficient concordance was 83.87%.
Conclusion
Annual vaccination in sheep has an effect on maintaining adequate protection against rabies by measurements of anti-rabies antibody response. Lambs need to be vaccinated earlier than 6 months of age to achieve protective levels of neutralizing antibodies in their serum. Introducing this ELISA in Sri Lanka will be a good opportunity to determine the level of anti-rabies antibodies in animal serum samples.
