BACKGROUND: The predictive validity of the Low Back Pain Perception Scale is determined in two studies in general practice and showed sufficient discriminative ability, although the psychometric properties of the scale have never been established until now.OBJECTIVE: To determine the reliability and validity of the Low Back Pain Perception Scale in acute nonspecific low back pain patients.METHODS: The Low Back Pain Perception Scale has been authorized translated into Dutch by two bilingual content experts. A sample of 84 acute low back pain patients in physiotherapy primary care, mean age (SD) age 42 (12) years participated in this study. Internal reliability and a test-retest procedure within one-week interval were evaluated.RESULTS: The internal consistency Cronbach α=0.38 (95% CI 0.09 to 0.56) and test - retest reliability within one week Intra Class Correlation coefficient=0.50 (95% CI 0.31 to 0.64). Minimal Detectable Change was measured 1.95. The concurrent validity demonstrates Pearson's r=0.35 (95% CI 0.14 to 0.53).CONCLUSIONS:The Low Back Pain Perception Scale demonstrates poor internal consistency and reliability and moderate concurrent validity. Extreme high or low scores may be clinical relevant therefore the scale can be used as a first screening instrument.

The instrument called Families Importance in Nursing Care-Nurses' Attitudes (FINC-NA) is used to measure nurses' attitudes toward involving families in their nursing care. The aim of this study is to evaluate the FINC-NA scale in a population of Dutch nurses and add new psychometric information to existing knowledge about this instrument. Using a cross-sectional design, 1,211 nurses received an online application in 2015. Psychometric properties were based on polychoric correlations and the Generalized Partial Credit Model. A total of 597 (49%) nurses responded to the online application. Results confirmed a four-subscale structure. All response categories were utilized, although some ceiling effects occurred. Most items increase monotonically, and the majority of items discriminate well between different latent trait scores of nurses with some items providing more information than others. This study reports the psychometric properties of the Dutch language FINC-NA instrument. New insights into the construct and content of items enable the possibility of a more generic instrument that could be valid across several cultures.
Cross-sectional multicentre study to investigate (1) the diagnostic value of the Signs of Depression Scale (SODS) in a Likert scale format and (2) whether the Likert scale improves the diagnostic value compared with the original dichotomous scale. A total of 116 consecutive hospitalized stroke patients, of whom 53 were patients with communicative impairment.
