This paper presents Tiltification, a multi modal spirit level application for smartphones. The non-profit app was produced by students in the master project “Sonification Apps” in winter term 2020/21 at the University of Bremen. In the app, psychoacoustic sonification is used to give feedback on the device’s rotation angles in two plane dimensions, allowing users to level furniture or take perfectly horizontal photos. Tiltification supplements the market of spirit level apps with the unique feature of auditory information processing. This provides for additional benefit in comparison to a physical spirit level and for more accessibility for visu- ally and cognitively impaired people. We argue that the distribution of sonification apps through mainstream channels is a contribution to establish sonification in the market and make it better known to users outside the scientific domain. We hope that the auditory display community will support us by using and recommending the app and by providing valuable feedback on the app functionality and design, and on our communication, advertisement and distribution strategy.

Objectives: To investigate the prevalence of depressive symptoms in rheumatoid arthritis (RA) patients using two previously validated questionnaires in a large patient sample, and to evaluate depressive symptoms in the context of clinical characteristics (e.g. remission of disease) and patient-reported impact of disease. Methods: In this cross-sectional study, the previously validated Patient Health Questionnaire (PHQ-9) and Beck-Depression Inventory II (BDI-II) were used to assess the extent of depressive symptoms in RA patients. Demographic background, RA disease activity score (DAS28), RA impact of disease (RAID) score, comorbidities, anti-rheumatic therapy and antidepressive treatment, were recorded. Cut-off values for depressive symptomatology were PHQ-9 >5 or BDI-II >14 for mild depressive symptoms or worse and PHQ-9 > 10 or BDI-II > 20 for moderate depressive symptoms or worse. Prevalence of depressive symptomatology was derived by frequency analysis while factors independently associated with depressive symptomatology were investigated by using multiple logistic regression analyses. Ethics committee approval was obtained, and all patients provided written informed consent before participation. Results: In 1004 RA-patients (75.1% female, mean±SD age: 61.0±12.9 years, mean disease duration: 12.2±9.9 years, DAS28 (ESR): 2.5±1.2), the prevalence of depressive symptoms was 55.4% (mild or worse) and 22.8% (moderate or worse). Characteristics independently associated with depressive symptomatology were: age 2 (OR = 10.54) and presence of chronic pain (OR = 3.25). Of patients classified as having depressive symptoms, only 11.7% were receiving anti-depressive therapy. Conclusions: Mild and moderate depressive symptoms were common in RA patients according to validated tools. In routine clinical practice, screening for depression with corresponding follow-up procedures is as relevant as incorporating these results with patient-reported outcomes (e.g. symptom state), because the mere assessment of clinical disease activity does not sufficiently reflect the prevalence of depressive symptoms.

Einleitung: Patienten mit rheumatoider Arthritis (RA) haben ein erhöhtes Risiko, an Diabetes mellitus (DM) zu erkranken. Wenig bekannt ist, welche Zusammenhänge es gibt zwischen DM als Komorbidität, Übergewicht und Krankheitsaktivität.

Objective: To validate standard self‐report questionnaires for depression screening in patients with rheumatoid arthritis (RA) and compare these measures to one another and to the Montgomery‐Åsberg Depression Rating Scale (MADRS), a standardized structured interview. Methods: In 9 clinical centers across Germany, depressive symptomatology was assessed in 262 adult RA patients at baseline (T0) and at 12 ± 2 weeks followup (T1) using the World Health Organization 5‐Item Well‐Being Index (WHO‐5), the Patient Health Questionnaire (PHQ‐9), and the Beck Depression Inventory II (BDI‐II). The construct validity of these depression questionnaires (using convergent and discriminant validity) was evaluated using Spearman's correlations at both time points. The test-retest reliability of the questionnaires was evaluated in RA patients who had not undergone a psychotherapeutic intervention or received antidepressants between T0 and T1. The sensitivity and the specificity of the questionnaires were calculated using the results of the MADRS, a structured interview, as the gold standard. Results: According to Spearman's correlation coefficients, all questionnaires met convergent validity criteria (r > |0.50|), with the BDI‐II performing best, while correlations with age and disease activity for all questionnaires met the criteria for discriminant validity (r < |0.50|). The only questionnaire to meet the predefined retest reliability criterion (r > 0.70) was the BDI‐II (rs = 0.77), which also achieved the best results for both sensitivity and specificity (>80%) when using the MADRS as the gold standard. Conclusion: The BDI‐II best met the predefined criteria, and the PHQ‐9 met most of the validity criteria, with lower sensitivity and specificity.
