Results The FreKAQ-J had acceptable internal consistency , unidimensionality , good test-retest reliability , and was functional on the category rating scale .
The FreKAQ-J was significantly correlated with pain in motion , disability , pain-related catastrophizing , fear of movement , and anxiety symptomatology .
Conclusions We developed FreKAQ-J by modifying the FreBAQ-J. The FreKAQ-J fits the Rasch measurement model well and is suitable for use in people with knee OA .
Background Recent systematic review s have demonstrated that pain associated with knee osteoarthritis ( OA ) is a complex phenomenon that involves various contributors .
People with knee OA exhibit symptoms of impaired body-perception , including reduced tactile acuity , impairments in limb laterality recognition , and de grade d proprioceptive acuity .
The Fremantle Back Awareness Question naire ( FreBAQ ) was developed to assess body-perception specific to the back in people with chronic low back pain .
The aim of this study was to develop and assess the psychometric properties of a knee-specific version of the FreBAQ-J ( FreKAQ-J ) , determine whether people with knee pain experience perceptual impairments and investigate the relationship between disturbed self-perception and clinical status .
Factor structure of the Hospital Anxiety and Depression Scale in Japanese psychiatric outpatient and student populations
Background The Hospital Anxiety and Depression Scale ( HADS ) is a common screening instrument excluding somatic symptoms of depression and anxiety , but previous studies have reported inconsistencies of its factor structure . The construct validity of the Japanese version of the HADS has yet to be reported . To examine the factor structure of the HADS in a Japanese population is needed . Methods Exploratory and confirmatory factor analyses were conducted in the combined data of 408 psychiatric out patients and 1069 undergraduate students . The data pool was r and omly split in half for a cross validation . An exploratory factor analysis was performed on one half of the data , and the fitness of the plausible model was examined in the other half of the data using a confirmatory factor analysis . Simultaneous multi-group analyses between the subgroups ( out patients vs. students , and men vs. women ) were subsequently conducted . Results A two-factor model where items 6 and 7 had dual loadings was supported . These factors were interpreted as reflecting anxiety and depression . Item 10 showed low contributions to both of the factors . Simultaneous multi-group analyses indicated a factor pattern stability across the subgroups . Conclusion The Japanese version of HADS indicated good factorial validity in our sample s. However , ambiguous wording of item 7 should be clarified in future revisions
