T1  - Reliability and validity of MoMo-Physical-Activity-Questionnaire for Adolescents (MoMo-AFB)
JF  - Diagnostica
N2  - This paper presents the psychometric properties of the MoMo-AFB (Bos, Worth, Opper, Oberger & Woll, 2009), a questionnaire designed to measure the physical activity of children and adolescents. The MoMo-AFB consists of 28 items, covering the fields of everyday physical activity, sports within and outside of organised clubs, physical education as well as compliance with physical activity guidelines. A study was conducted with 109 boys and 87 girls aged between 9 and 17 years. The MoMo-AFB was given on two separate occasions to evaluate reliability and was compared with accelerometry data of ActiGraph GT1X to evaluate validity. The overall kappa/weighted kappa coefficient for the one-week testretest reliability was .66 (SD = .19) and the overall intraclass correlation (ICC) .68. Self-reported and accelerometer-measured average weekly time spent performing moderate to vigorous physical activity were significantly correlated (Spearman r = .29). Regarding reliability and validity, the MoMo-AFB is comparable with other international published physical activity questionnaires for adolescents.

T1  - Cognitive flexibility in adolescent patients with unipolar affective disorders - gender differences
JF  - Zeitschrift für Kinder- und Jugendpsychiatrie und Psychotherapie
N2  - Objective: Several studies have revealed impairments in cognitive functions among patients with affective disorders (AD). However, to date there are few neuropsychological studies on cognitive flexibility among adolescent patients with AD, especially on gender differences in AD. Here, we investigate cognitive functions, especially cognitive flexibility, in adolescent patients with unipolar AD (UAD) compared to a healthy control group (CG). Method: The study population consists of 17 male patients (M-age = 15.4 +/- 1.3) and 22 female patients with UAD (M-age = 15.6 +/- 1.4) as well as 20 male (M-age = 16.0 +/- 1.0) and 30 female (M-age = 15.7 +/- 0.9) healthy adolescents. A neuropsychological test battery was conducted, and depressive symptoms, psychological stress, and intelligence were also assessed. Results: The analyses revealed no significant group differences regarding cognitive flexibility or visual processing speed, albeit slight better performance in motor processing speed for the CG. Furthermore, no gender differences were observed regarding cognitive flexibility, though female subjects general displayed better performance in processing speed. Conclusions: Overall, there are no indications for serious deficits and specific gender differences in cognitive flexibility or processing speed in adolescent patients with UAD. Independent of psychological distress, female subjects seem to have some advantages in processing speed.
