The purpose of this study was to explore heterosexual bias in the diagnosis and treatment of gay males. Two hundred-fifty (134 males and 116 females) mental health professionals from the Division of Psychotherapy (29) of the American Psychological Association participated in the study. Participants were randomly assigned to one of two case history conditions, which presented a 35-year-old male seeking therapy. Both conditions were equivalent with regards to the presenting problem (i.e., diagnostic symptoms) with the exception of his significant other (i.e., gay vs. non-gay condition). Potential bias was measured through a diagnostic rating Likert scale and a treatment plan questionnaire. Other independent variables that could potentially have an effect on diagnostic ratings were explored, such as gender, year of graduation, and theoretical orientation of the respondents. Results of the statistical analyses failed to confirm evidence of heterosexual bias. Implications for further research and training are discussed.

The early diagnosis of CP (Cerebral Palsy) in infants is important for developing meaningful interventions. One of the major symptoms of the CP is lack of the coordinated movements of a baby. The bilateral coordinated movement (BCM) is that a baby shows in the early development stage. Each limb movement shows various ranges of speed and angle with fluency in a normal infant. When a baby has CP the movements are cramped and more synchronized. A quantitative method is needed to diagnose the BCM. Data is collected from 3-axis accelerometers, which are connected, to each limb of the baby. Signal processing the collected data using short time Fourier transforms, along with the formation of time-dependent transfer functions and the coherence property is the key to the diagnostic approach. Combinations of each limb's movement and their relationship can represent the correlated movement. Data collected from a normal baby is used to develop the technique for identifying the fidgety movement. Time histories and the resulting diagnostic tool are presented to show the regions of the described movement. The evaluation of the transduction approach and the analysis is discussed in detail. The application of the quantitative tool for the early diagnosis of CP offers clinicians the opportunity to provide interventions that may reduce the debilitating impact this condition has on children. Tools such as this can also be used to assess motor development in infants and lead to the identification and early intervention for other conditions. / Master of Science
