The purpose of the current study was to explore how youth make sense of the experience of living with a service member (SM) parent with an opertational stress injury (OSI). Research suggests that youths living with an SM with an OSI are at a higher risk of developing mental health disorders and behavioural problems, as well as achieving lower academic outcomes (Stelnicki & Schwartz, 2016). Studies have also shown that OSIs such as posttraumatic stress disorder, negatively impact an SM’s ability to parent and engage with their child (Creech & Misca, 2010). However, while these challenges have been identified in the literature, limited research has examined the firsthand experiences of adolescents living with an SM parent with an OSI. Furthermore, little attention has been paid to resilience in military-connected youth (MCY) and how MCY might cope with the challenges that come with parental OSI. Given these two gaps in knowledge, I explored youths’ experiences of living with an SM parent with an OSI by asking the question: How might we understand how adolescents make sense of their experience of living with an SM parent with an OSI? I used the qualitative research methodology, Interpretative Phenomenological Analysis (IPA), to guide this multi-perspectival study. Using purposive and snowball sampling, I recruited 11 adolescents (14-18 years old), who met the inclusion criteria. Five participants were female while six were male, with a mean age of 16.3 years old. I conducted audio-taped, in-depth, semi-structured interviews with each participant. Interviews were analyzed to produce a set of themes that reflected the ways in which MCY understood their experience. The study findings included four overarching themes: (a) Making Sense of Parental OSI, (b) Repercussions of Living With Parental OSI, (c) Coping, and (d) Resiliency. These findings are discussed in the context of relevant literature. The strengths and limitations of the study are considered and implications for theory, research, practice, and policy are presented.
