This study used a single case design to explore the relationship between individual child-centered play therapy on children with developmental delays by examining its effectiveness in: 1) increasing measured developmental age; 2) reducing problematic behaviors related to developmental delays; and 3) increasing developmentally appropriate behaviors. Three participants were assessed weekly with both developmental and behavioral measures during the three phases of the study: baseline, intervention, and follow up. Additionally, parents of the participants completed behavioral measures at pretest, midpoint, and posttest administrations. The participant's weekly standard scores were graphed and results were examined separately using visual analyses. Changes between phases: non-intervention baseline, intervention, and non-intervention follow-up were examined; specifically, the level, trend, and variability of the data across the phases were examined. Each of the three participants served as their own control group in this single case analysis and their results, and all three of the participants demonstrated improvement on the developmental measures after receiving the play therapy intervention. Results from this single case analysis suggest the need for further replication, use and reporting of single case interventions and designs, to promote the efficacy of counseling interventions and to potentially enhance the literature and research base for evidence based interventions.

College counselors today face increasing challenges, with fewer resources than in the past. Little has been known as to whether college counselors take advantage of resources and benefits available through involvement in professional organizations in these increasingly challenging professional times. College counseling center professionals in one state in the Southwest were surveyed regarding their professional organization involvement (N = 152). Participants were selected by targeting specific 4-year institutions with undergraduate populations and specific counseling professionals who work in college counseling centers within these schools. Most college counselors surveyed were involved in professional organizations, and involved in a variety of ways within these organizations. Many professional organizations catering to college counselors were identified. Specific motivations for involvement and hindrances to involvement were identified. In addition, no significant difference was found among the involvement of professional counselors versus psychologists.

Although professional counselors have distinguished themselves among helping professionals through a focus and foundational framework in normal human growth and development over the life-span, a majority of programs neglect to incorporate training opportunities enabling students to translate developmental theory to clinical practice. In this mixed-method study, the researcher explored the effects of a human developmental counseling application curriculum and examined cognitive complexity levels among counselor trainees. Qualitative results support gains in both the integration and application of developmental content while quantitative results offer partial support for cognitive complexity gains among trainees. This study identifies a curricular training experience in which counselor trainees' integration and application human developmental theory as well as cognitive complexity, are notably enhanced.
