q3 · i? · associational · r2

Attrition analysis in the four-wave longitudinal study (290 consented; 214, 73.8%, completed the final wave). No significant differences were found in gender, age, family structure, SES, or the other study variables; Little's MCAR test was not significant.

"there was a significant difference between adolescents who participated at all time points and those who dropped out in terms of peer victimization, F (1, 270) = 6.85, p = .009, indicating that participants who withdrew from the study reported more peer victimization."

Discussion¶

Related Claims¶

• Longitudinal subject attrition produces systematic baseline differences among continuing, dropout, and non-participating students — a broader claim this one bears on
• Youth lost to attrition had discussed immigration more frequently and reported lower hope and peer validation at baseline — related
• Attrition of 130 students (35%) between pretest and posttest was not systematically related to baseline characteristics — related
