In this paper the test control criteria of the sport-specific Affiliation Motives Scale-Sport are reported. Theoretical background for the development of the scale is the affiliation motive, which is composed of the two factors “hope for affiliation”and “fear of rejection” (Mehrabian and Ksionzkys, A theory of affiliation, 1974). The factor analysis, which was conducted after an item analysis, displayed a two-factor structure and identified the two scales “hope for affiliation” and “fear of rejection” in sports. These two factors could be confirmed by a Confirmatory Factor Analyses. Furthermore, the questionnaire shows satisfactory Cronbach’s alpha. Construct validity is shown through correlations with two general questionnaires to measure the affiliation motive (Krippl, Itemanalytische Untersuchungen zur Selbstbeschreibung von Emotion und Motivation, 1999; Teubel, Eine deutsche Übersetzung der Mehrabian-Skala zur Erfassung des Anschlussmotivs, 2009) and two scales of the German Personality Research Form (Stumpf et al., Deutsche Personality Research Form(PRF), 1985). Validity is additionally shown through significant group differences between team and individual athletes as well as by significant differences between top-level and recreational volleyball players.
