This dissertation investigated counseling students' professional identity, locus of control, and their impact on counseling students' attitudes toward professional help-seeking in the United States. For the aim of this quantitative study, a correlational research design to explore possible causal relationships among variables using multiple regression, two-way ANOVA, and Pearson correlation coefficient analysis was implemented. The researcher used the Demographic Questionnaire, Attitudes Toward Professional Help Seeking Scale-Short Form (ATPHS-SF), Professional Identity Scale in Counseling-Short Form (PISCSF), and Locus of Control Scale. According to the stepwise regression Model 2 (Professional Identity and Learning Environment) was the best model to predict ATPHS, explaining 5.7% of the variance in the dependent variable. Spearman's rank correlation test demonstrated that professional competency, attitudes towards the profession and PISC Total had the highest correlations with the dependent variable of ATPHS. Two-way ANOVA and Pearson correlation analysis were used to explore the relationship between variables. According to the results of the two-way ANOVA and Pearson correlation, age, and ATPHS were positively correlated. The findings of this study provide implications for counseling leaders, counselor educators, and advisors of counseling students to train future professional counselors. Limitations and suggestions for future research will be discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
