Following the events that transpired after 9/11, evidence suggested that the mental health of Muslims across the globe was affected significantly, resulting in decreased wellness for members of this group. Hate crimes toward Muslims and those perceived as Muslim increased. Though the implications of this major event were evident for adults, little research has examined the ramifications on youth growing up during this time. In the present study, a grounded theory approach was utilized to examine the identity development of Muslims growing up in the age of the "war on terrorism." Nine students (3 females, 6 males) participated in the current study, and represented undergraduate (4) and graduate students (5). Participants completed two phases of data collection. The first was an open-ended interview questionnaire completed online. The second phase consisted of an in-depth interview. The results of the present study yielded three models. The first described the experience of being Muslim on a Catholic campus. At the core of students' experiences was an appreciation of the campus' spirituality. It was defined by four interconnected dimensions: connection with a spiritual community; a sense of uniqueness and pride; appraisal of student attitudes; and overcoming challenges and barriers. The second model answered the primary question of the investigation which sought to understand the identity development of Muslim youth who grew up in the United States during 9/11. Results suggested a two-tiered interconnected multidimensional model, with a core made up of the collectivistic self. The inner ring of the model depicts elements most central to the participants' identity and included: family; ethnic heritage; and religion (Islam). The outer ring illustrates domain that were also important but less salient and included: region; field of study; ethnic minorities; social justice; hobbies; and SES. The third model was a moderation model and depicted the effects of 9/11 on participants' lives. It was evident that participants were exposed to discrimination and resulting negative repercussions. Despite this, their positive coping strategies appeared to significantly mitigate its effects. Limitations and challenges of the present study are discussed. Future directions and practical applications are also provided.
