What the data showed.

Table 1 · Descriptive Statistics

By sex

Variable	Female · M (SD)	Male · M (SD)
Age	20.21 (1.53)	20.67 (1.81)
Cum. GPA	3.49 (0.59)	3.40 (0.48)
APS-S total	76.00 (14.27)	73.15 (12.69)
GAD-7 total	11.16 (6.08)	6.39 (4.81)
BSMAS total	16.42 (5.34)	15.48 (4.59)

Female and male students had similar ages and cumulative GPAs. Female students reported notably higher GAD-7 anxiety. Sex differences in BSMAS and APS-S were small.

Multiple linear regression

Models predicting GPA and anxiety

GPA from APS-S, sex, and APS-S × Sex

GPA = 4.65 − 0.015·APS − 0.55·G + 0.006·(APS·G)

Procrastination significantly predicted lower GPA. The sex interaction was not significant.

GPA from BSMAS, sex, and BSMAS × Sex

GPA = 3.697 − 0.013·BSMAS − 0.162·G + 0.004·(BSMAS·G)

BSMAS did not uniquely predict GPA. No significant sex interaction.

Anxiety (GAD-7) from BSMAS, sex, and BSMAS × Sex

GAD-7 = 7.15 + 0.24·BSMAS − 4.62·G − 0.01·(BSMAS·G)

Higher BSMAS predicted higher anxiety. Female students reported higher anxiety overall. No significant interaction.

Bottom line

Procrastination tracked GPA. Social media addiction tracked anxiety. No sex interactions reached significance.
