N = 309. Indices with minimal difference have been represented upto 3 places of decimal

Proposed model: Direct relation between TE & AE, FMS, FRS, ITS & AE, and AE & PWB + Direct relation between TE & PWB and FMS, FRS, ITS & PWB

Model 1: Direct relation between TE & AE, FMS, FRS, ITS & AE, and AE & PWB + Direct relation between TE & PWB

Model 2: Direct relation between TE & AE, FMS, FRS, ITS & AE, and AE & PWB + Direct relation between FMS, FRS, ITS & PWB

Model 3: Direct relation between TE & AE, FMS, FRS, ITS & AE, and AE & PWB

Df: Degrees of freedom; RMSEA: Root-mean-square error of approximation; SRMR: Standardized root-mean-square residual; CFI: Comparative fit index

TE: Team Environment; FMS: Family Support; FRS: Friends Support; ITS: Institutional Support; AE: Academic Engagement; PWB: Psychological Well-being
