“…The German PND version has been previously evaluated (Leoni‐Scheiber, Gothe, & Müller‐Staub, ). The psychometric properties of the original PND showed favourable results: its content validity exceeded an agreement of 90% by four expert raters (Lunney & Krenz, ), the test–retest reliability as measured by intraclass correlation coefficient was 0.90 (95% CI [0.87, 0.92]), and the internal consistency as measured by Cronbach's alpha coefficient was 0.96 (Romero‐Sánchez, Paloma‐Castro, et al, ). The construct validity was measured by confirmatory factor analysis and showed highly correlated factors in the three‐factor model solution (≥0.96) (D'Agostino et al, ).…”
