Abstract
Zusammenfassung. Untersucht wurde das „neue“ Persönlichkeitskonstrukt „Grit“, das die zwei korrelierten Primärfaktoren „beharrliche Anstrengungsbereitschaft“ („Perseverance of Effort“, PE) und „konsistentes Interesse“ („Constistency of Interest“, CI) in einem Wert zusammenfasst. Grit soll nach Duckworth (2016) Erfolg in Schule, Hochschule, Beruf und Leben besser als Intelligenz und klassische Persönlichkeitsvariablen vorhersagen. Credé, Tynan und Harms (2017) bezweifelten als Resultat ihrer Metaanalyse die hierarchische Grit-Struktur, die behauptete starke Vorhersagekraft für akademische Leistungen konnten sie nicht bestätigen. Weiterhin wurde eine sehr hohe Korrelation von PE mit Gewissenhaftigkeit ermittelt. Bisherige Studien stammen hauptsächlich aus individualistisch orientierten Gesellschaften. Deshalb wurde Grit in einer kollektivistisch orientierten Kultur (China) untersucht (N = 533, Alter: M = 15.16 Jahre, SD = 0.64). Zusätzlich erhoben wir Gewissenhaftigkeit, schulische Selbstwirksamkeit und schulisches Selbstkonzept. Das Mittel der schulischen Fachleistungspunkte wurde berechnet. Die Gesamtstichprobe wurde in zwei randomisierte Substichproben geteilt. Explorative Hauptkomponentenanalysen (Substichprobe 1: n1 = 200) und konfirmatorische Faktorenanalysen (Substichprobe 2: n2 = 333) der Grit-Items erbrachten zwei unkorrelierte Dimensionen, PE und CI. PE korrelierte sehr hoch mit Gewissenhaftigkeit (r = .73, doppelt schrumpfungskorrigiert: r ∞, ∞ = .90). Die Beziehungen von PE zu Selbstwirksamkeit und Selbstkonzept waren hoch (r = .55 bzw. r = .58), zur Schulleistung sehr niedrig (r = .08). CI hing nur mit Selbstwirksamkeit bzw. Selbstkonzept schwach zusammen (r = –.13 bzw. r = –.15), nicht mit Gewissenhaftigkeit (r = .01) und dem Durchschnitt der Schulleistungspunkte (r = –.02). Alles zusammen begründet Zweifel an Grit als „neues“ und valides leistungsbezogen-motivationales Persönlichkeitsmerkmal – zumindest bei chinesischen Adoleszenten.
Abstract.Duckworth, Peterson, Matthews, and Kelley (2007) introduced “grit” as a “new” performance-related motivational trait. It is conceptualized as a higher-order factor which is based on the amalgamation of the two primary factors “Perseverance of Effort” (PE) and “Consistency of Interest” (CI). Duckworth (2016) claimed that grit predicts academic achievement better than intelligence and traditional personality traits. A meta-analysis by Credé, Tynan, and Harms (2017) did not at all confirm Duckworth's assertion and casted doubts on the higher-order structure of grit and on the predictive power of grit for academic performance. Moreover, this meta-analysis revealed that PE is strongly related to conscientiousness. Most grit studies were conducted in individualistic oriented (western) cultures. Research comprising samples from collectivistic (far eastern) cultures is scare. The present study is aimed to shed some light on the factorial structure and performance related validity of the original grit-scale among a sample of N = 533 Han-Chinese middle-school students (age: M = 15.16, SD = 0.64). Conscientiousness, academic self-efficacy, and academic self-concept were additionally measured. The Grade Point Average (GPA) was used as an indicator of academic performance. The sample was randomly split into two subsamples. Principal component analyses (subsample 1: n1 = 200) and confirmatory factor analyses (subsample 2: n2 = 333) revealed two completely independent dimensions, PE and CI, thus indicating that the amalgamation of both facets into one single grit-score made no sense. The internal consistencies of the PE-scale and of the CI-scale were satisfactory. A very high correlation of the PE-scale with conscientiousness was found (r = .73, after correction for attenuation r ∞,∞ = .90) as well as high correlations with self-efficacy (r = .58) and self-concept (r = .55). The relationship of PE with GPA was insignificant and small (r = .08). The CI-scale was not all related to GPA (r = –.02) and conscientiousness (r = .01) and weakly correlated with self-efficacy (r = –.13) and self-concept (r = –.15). Taken together, these findings cast serious doubts on grit as a new and valid achievement tied motivational construct – at least among Chinese adolescents.
