The population of adults age 65 and older in the United States (U.S.) is expected to double by the year 2065. According to the American Psychological Association, 63% of older adults diagnosed with a mental disorder do not receive mental health services. The increase and longevity of the population, along with the underutilization of services by this population reflects a need for mental health clinicians to be trained and willing to work with older adults; however, it is not typically common for psychology doctoral students to express interest in treating older adults. The purpose of this dissertation research is to examine clinical psychology doctoral students' attitudes toward older adults and the desire to treat or not to treat the older adult population. A phenomenological qualitative design was utilized for this study. Clinical psychology doctoral students were interviewed individually by the researcher and answered questions related to their population of interest, their previous clinical experiences, and view of clinical work with the older adult community. An exploratory and semi-structured interview was used to gather information. Specific areas addressed in the interview were the students' self-defined population(s) of interest, previous professional and personal experiences with older adults, perceived competence in treating older adults, and attitudes toward treating older adults. Data was examined to find patterns and/or themes related to the research questions. The data indicated several common themes that represent shared experiences related to aging and older adulthood among clinical psychology doctoral students. The data indicated several common themes that represent shared experiences related to aging and older adulthood among clinical psychology doctoral students. Most research questions this study sought to explore were answered by participants. Specifically, participants shared that they believed doctoral programs should provide training to work with this population. Furthermore, participants identified that if training could be applicable to them, they would be interested in pursuing it. Participants shed light on the importance of exposure to different populations. Specifically, all participants shared prior positive experiences with the population they identified as their population of interest. Students were open to discussing their fears about aging and identified that these fears may be due to outside influences such as media, literature, or family. This study brought up important considerations when trying to increase interest in work with the older adult population. Identified themes are mostly consistent with current research and emphasize the need to continue research in this area. Ageism and lack of positive experiences with older adults appear to be contributing factors to the lack of interest in treating older adults.
