Cross-cultural translation and adaptation of the Danish version of the brief version of the 10-item Big Five Inventory.

BACKGROUND: Personality traits are associated with pain-related beliefs and coping strategies, and different chronic conditions are linked through specific personality profiles. This highlights the importance of having valid and reliable measures of personality traits for use in clinical and research settings when assessing patients in chronic pain. PURPOSE: To translate and cross-culturally adapt the 10-item Big Five Inventory (BFI-10) into Danish. METHODS: A bilingual expert panel (N = 4) and a panel of laymen (N = 8) translated and culturally adapted the questionnaire into Danish. Face validity was evaluated in a group of persons suffering from recurring or ongoing painful conditions (N = 9). Data were collected to evaluate the internal consistency, test-retest reliability and factor structure (N = 96). RESULTS: Some of the participants in the lay panel considered the questionnaire too short, considering its aim of assessing personality. Acceptable internal consistency was found for two out of five subscales (0.78 for both Extraversion and Neuroticism), while the internal consistency was non-acceptable for the remaining subscales (0.17-0.45). Test-retest reliability was acceptable for three subscales (0.80 for Neuroticism, 0.84 for Conscientiousness, and 0.85 for Extraversion). Assumptions for determining the factor structure were not met and therefore was this analysis omitted. DISCUSSION: Although face valid, only two out of five subscales had acceptable internal consistency and only three subscales had acceptable test-retest reliability. These findings indicate that interpreting findings regarding personality using the Danish BFI-10 should be done with caution.

Cross-cultural adaptation of the Danish version of the Big Five Inventory - a dual-panel approach.

Background and aims Assessing personality in research can be of importance, especially due to the potential relationship between different personality traits and the manifestation of symptoms in different clinical conditions. Therefore, it is important to have valid and reliable tools that allow for the assessment of personality traits. In this study, the aim was to translate and culturally adapt the Big Five Inventory (BFI) to the Danish language. Methods A dual panel approach, consisting of a 4-person bilingual panel and an 8-person panel with laymen, was used to translate and culturally adapt the questionnaire. A third 9-person panel consisting of people with different medical diagnosis was used to assess the face validity. Internal consistency (Cronbach's α) and test-retest reliability (intraclass correlation coefficients (ICC)) were tested amongst 96 subjects. Results The translated version demonstrated adequate internal consistency (0.66-0.84) and good-excellent test-retest reliability (0.86-0.95). The smallest detectable change is between 1.13-1.70 for the five subscales. Both the healthy and patient panels of laymen considered the questionnaire too long. Conclusion This translated version of the Big Five Inventory demonstrated high to very high test-retest reliability and, for most parts, an acceptable internal consistency. The construct validity was however different from versions translated into languages geographically and culturally similar to Danish. Implications Assessing the Big Five personality traits in Danish populations can be valuable for many reasons, e.g. when assessing people in pain in both clinical and experimental settings. Improved knowledge of the underlying driver of pain conditions is important. Here, understanding how personality may interact with pain can help researchers and clinicians.

Agreement between physiotherapists rating scapular posture in multiple planes in patients with neck pain: Reliability study.

OBJECTIVE: Evaluation of scapular posture is an integral component of the clinical assessment of painful neck disorders. The aim of this study was to evaluate agreement between therapist judgements of scapula posture in multiple biomechanical planes in individuals with neck pain. DESIGN: Inter-therapist reliability study. SETTING: Research laboratory. PARTICIPANTS: Fifteen participants with chronic neck pain. MAIN OUTCOME MEASURES: Four physiotherapists recorded ratings of scapular orientation (relative to the thorax) in five different scapula postural planes (plane of scapula, sagittal plane, transverse plane, horizontal plane, and vertical plane) under four test conditions (at rest, and during three isometric shoulder conditions) in all participants. Inter-therapist reliability was expressed using both generalized and paired kappa coefficient. RESULTS: Following adjustment for expected agreement and the high prevalence of neutral ratings (81%), on average both the generalised kappa (0.37) as well as Cohen's Kappa for the two therapist pairs (0.45 and 0.42) demonstrated only slight to moderate inter-therapist reliability. CONCLUSIONS: The findings suggest that ratings of scapular posture in individuals with neck pain by visual inspection has only slight to moderate reliability and should only be used in conjunction with other clinical tests when judging scapula function in these patients.
