Suicidal Ideation among Adolescents as Topic of Research Interest Scientific research is supported logically and empirically (Babbie, 2017) by either an objective or subjective paradigm. Within the framework of the objective paradigm, the researcher who is removed from the subjects views the reality as any material object (Laureate education, 2016a). As far as my topic of interest as concerned, the researcher involves in predicting suicidal ideation among adolescents and takes control over this process. In such a case, theory can be built on survey design and random sampling interventions with a view to exploring how the world works that makes suicidal thought and attempts possible as early as the onset of adolescence. My area of interest – suicidal ideation among adolescents – involves the relationship between personality traits, culture, family structure, peer friendship, education as causes of suicidal ideation in two distinct groups, early adolescents and middle adolescents. My area of expertise will be in a mixed quantitative and qualitative research, for I am interested in finding the answer to the question why adolescents in the current technology advanced and deeply divided world are at risk of suicidal ideation. Epistemological Assumptions of Philosophical Orientations Epistemology is deals with scientific knowing achieved by scientific inquiry (Babbie, 2017). As knowledge is accumulative by nature, it is grounded in the known on which new knowledge is built. Each field of knowledge develops seminal research that presents the conceptual framework that is shared by all researchers in this field as fundamental and basic. The replication of fundamental theoretical backgrounds in another context or situation is the task of a researcher who supports the authority in the selected field. Epistemologically, positivism and interpretivism are objectivist philosophical assumptions, whereas social constructivism and realism are subjectivist ones. Scientific knowing has developed two main research designs, quantitative and qualitative. The former tests theory and hypothesis, determines relationship between variables, uses statistics, and shows testing. The latter creates research approach, asks what/who/when/where/why questions, utilizes non-numerical data, and develops conceptual framework. Most popular quantitative designs include correlation, quasi-experimental, experimental, factor analysis, and ex post facto ones. Qualitative designs include phenomenology, narrative, grounded theory, ethnography, and straight qualitative ones (Barbie, 2017). However, blended designs can be effectively used as well (Laureate education, 2016a), marked by the qualitative or quantitative dominant or interacting without triangulation. Epistemologically, the researcher possesses sources of knowing and is capable of acknowledging and controlling biases (Laureate education, 2016a).
