Kurzbeschreibung

|
Das Sportwissenschaftliche Institut des Bundesamtes für Sport hat in den letzten Jahren eine umfangreiche Datenbank mit Daten zum Erholungs-Belastungsfragebogen Sport (EBF-Sport; Kellmann & Kallus, 2000), sowie der deutschsprachigen Fassung des Profile of Mood States, erstellt. Die Faktorenlösung des Erholungs-Belastungsfragebogen wurde, trotz ermutigenden Ergebnissen im angewandten klinischen Einsatz, immer wieder kritisch hinterfragt. Das Profile of Mood States war zur Erfassung von Stimmungslagen das Instrument der Wahl der 80-er und 90-er Jahre in der englischsprachigen Sportpsychologie. Deren Validität wurde jedoch in den letzten Jahren von mehreren Autoren in Frage gestellt. Ein deutschsprachiges Instrument als Alternative stellen die Befindlichkeitsskalen (BFS) von Abele-Brehm und Brehm (1986) dar. Das Instrument wurde jedoch im breiten Umfang nur von Abele-Brehm und Brehm selber eingesetzt. Eine Validierung aus anderer Quelle existiert nicht, ganz abgesehen von einer englischsprachigen Version, die für die Vergleichbarkeit internationaler Studien von Nutzen wäre.

Abstract
Two studies were conducted in the attempt to further develop and refine the Recovery-Stress Questionnaire for Athletes (RESTQ-Sport) (Kellmann & Kallus, 2001). Confirmatory factor analytic procedures (CFA) were employed to test the hypothesized 19-factor structure of the instrument. The 76-item German version of the RESTQ-Sport was administered to 453 athletes. The original two-factor model did not result in an entirely satisfactory fit of the RESTQ-Sport as illustrated by absolute and relative fit indices. A lot of items seemed to be factorially ambiguous. Factor loadings, standardized residuals, and modification indices were used to identify problematic items. Item content was then used to determine whether a problematic item should be removed. In study 2, the revised questionnaire, consisting of 54 items forming 14 different scales, was administered to 282 athletes. Regarding to the fit indices our solution fitted the data moderately well. As demonstrated by the AIC's the new factor solution was better and more parsimonious as the original factor solution.
Unraveling Affect Measurement in Sport Psychology Research:
The Circumplex Mood Inventory

Abstract
Confirmatory factor analysis (CFA) was used to examine the validity of an English translation of the 'Befindlchkeitsskalen' (mood scales) of Abele-Brehm and Brehm (1986), here referred to as the Circumplex Mood Inventory (CMI). The underlying categorical-dimensional circumplex structure of affect, with the 2 bipolar dimensions of valence and activation, was tested using the special covariance structure approach provided by the program CIRCUM. The modified 30-item scale, forming 4 positive and 4 negative mood categories, revealed a reasonable fit. The circumplex structure could be shown for 7 of the 8 categories with an adequate fit. Three pairs of mood categories, lying in the circumplex model opposite of each other, probably representing an appetitive motivational system (positive affect) and an aversive motivational system (negative affect), emerged for the analysis. The balanced positive / negative structure provides a functional and possibly more ecologically valid avenue in sport and exercise, and measures not primarily the absence of negative affect.
