“…Results of the item analysis are shown in Table 2 . Item difficulty was within the desired range (20–80%) and corrected item-scale correlations were good (> 0.5) [ 21 ]. Internal consistency of the CHIQ was good with Cronbach’s α = 0.88.…”

Background Cluster headache (CH) is a severe, highly disabling primary headache disorder. However, there is little research on CH-related disability, and most of it is based on non CH-specific questionnaires. The aim of this study was to develop a short, CH-specific disability questionnaire. Methods The 8-item Cluster Headache Impact Questionnaire (CHIQ) was developed based on a literature review and patient and expert interviews. The questionnaire was tested in 254 CH patients (171 males; 47.5 ± 11.4 years; 111 chronic CH, 85 active episodic CH, 52 episodic CH in remission) from our tertiary headache center or from a German support group. Results Reliability and validity of the CHIQ was evaluated in active episodic and chronic CH patients (n = 196). Internal consistency (Cronbach’s α = 0.88) and test-retest reliability (ICC 0.91, n = 41) were good. Factor analysis identified a single factor. Convergent validity was shown by significant correlations with the Headache Impact Test (HIT-6, r = 0.58, p < 0.001), subscales of the depression, anxiety and stress scales (DASS, r = 0.46–0.62; p < 0.001) and with CH attack frequency (r = 0.41; p < 0.001). CHIQ scores significantly differentiated between chronic CH (25.8 ± 6.5), active episodic CH (23.3 ± 6.9) and episodic CH patients in remission (13.6 ± 11.9, p < 0.05 for all 3 comparisons). Conclusions The CHIQ is a short, reliable, valid, and easy to administer measure of CH-related disability, which makes it a useful tool for clinical use and research.

“…The purpose of the difficulty index is to distinguish between patients with high and low symptom expression. Therefore, items that are answered “yes” or “no” by all test persons do not provide much information [ 27 ]. The item difficulty (P i ) was calculated: P i = (item mean X i /maximum score) ×100.…”

Background There is no patient-reported functional scale specific for osteochondral lesion of the ankle (OCLA). Therefore, the objectives of this study were to develop a questionnaire that measures symptom severity, function, and sports capacity in patients with osteochondral lesions of the ankle and to determine the psychometric properties of the tool in German language (OCLA-G). Methods The OCLA-G questionnaire was developed according to the COSMIN guidelines. Scalable items were generated from a literature search, based on an evaluation of 71 own OCLA patients, and from expert opinions. Following a twofold item reduction the questionnaire underwent explorative data analysis and principal component analysis. Validity and reliability were analysed in four groups of participants (40 patients with OCLA, 40 patients with other foot and ankle injuries, 40 asymptomatic athletes serving as a population at risk, and 40 asymptomatic persons playing sports not at risk). The minimum age for participation in the study was set at 18 years. The mean age was 39.3 ± 15.1 years. Results The final OCLA-G questionnaire consists of eight and five questions to mirror activities of daily life (ADL) and sports, respectively. Excellent internal consistency (Cronbach’s α = 0.950 for the ADL subscore and 0.965 for the sport subscale, respectively) was found. Spearman’s rank correlation coefficients for test-retest reliability were 0.992 for the ADL subscore and 0.999 for the sport subscale (p < 0.001). The results of the exploratory and confirmatory factor analyses indicated that item difficulty was between 23.4 and 62.8. The Pearson correlation for the OCLA subscales ADL and sport was 0.853 (p < 0.001). Construct validity as tested against the SF-12 questionnaire subscales (Physical and Mental component scale) were r = -0.164 to -0.663 (p < 0.05). Statistically, there was no ADL and sport OCLA mean score difference between OCLA patients and patients with other foot and ankle injuries (p = 0.993 and 0.179, respectively), but both groups differed from the uninjured control groups (p < 0.001). There were no ceiling or floor effects. Conclusions The OCLA-G was successfully developed as the first patient reported and injury specific outcome scale to measure the impact of OCLA induced symptoms on activities of daily living and sport. This study provides evidence for the reliability and validity of the OCLA-G assessing patients with OCLA. Trial registration The registration trial number is DRKS00009401 on DRKS. ‘Retrospectively registered’. Date of registration: 10/12/2015.
