This research study was designed to examine the relationships among secure attachment, gratitude, hope, ego-resiliency, and mental well-being in undergraduates by proposing a parallel multiple mediation model. The participants of this study were comprised 214 females and 145 males, a total of 359 undergraduates (60% female and 40% male) between 18 to 23 years old who were recruited from a state university in south of Turkey. To collect data, Relationship Scales Questionnaire, Gratitude Scale, Dispositional Hope Scale, Ego-Resiliency Scale, and Warwick-Edinburgh Mental Well-Being Scale were applied. The results showed that secure attachment, gratitude, hope, ego-resiliency, and mental well-being were positively correlated. The findings from the mediational analyses also indicated that the parallel multiple mediation of gratitude, hope and ego-resiliency in the hypothetical model was statistically significant and explained approximately 57% of the variance in mental well-being.
