The interplay between social interaction quality and wellbeing in military personnel during their initial two-years of service.

This research examined the nature of social interaction profiles in the initial two-years of military service, profile association to early vulnerability to psychological distress, and the association between supervisor interaction qualities in the likelihood of profile membership. Data were collected as part of a larger longitudinal study. Participants who completed key variables at either 3-12 months post-enlistment ( = 5,233; 85.6% male) or 15-24 months post-enlistment ( = 2,162; 79.2% male) were included in the cross-sectional profile analysis of social interaction quality from military and nonmilitary sources. Cross-sectional latent profile analyses and transition analysis were used to investigate the social interaction profiles at each time-point, the effect of leader interactions on movement between profiles, and related psychological distress outcomes. Social interaction quality, and in particular colleague interactions, was predictably associated with psychological distress. Leadership interactions were associated with the nature of colleague social interactions. Greater positive social interactions with leadership was related to a reduced likelihood of experiencing less frequent negative interactions with colleagues. The findings implicate a possible role for supervisors in perpetuating positive or negative colleague interactions. Moreover, a trajectory of vulnerability to psychological distress may start in the initial two-years of military service and emerge from the psychosocial context.
