Because of their invincible attitude, adolescents put themselves increasingly at risk for developing health problems due to life style choices. Lack of knowledge and misunderstanding can lead to choices that impact their health throughout life. Improved interactions with health care providers (HCP) are imperative to set appropriate goals for health. The Adolescent Transaction Scale (ATS) is a newly developed instrument to measure adolescent’s perceptions of interactions with HCP based on Imogene King’s operational definition of transaction. The objective of the pilot study was to psychometrically test the ATS and to determine its ability to discriminate between two groups whose perceptions of transaction were suspected to be different. The ATS is a 32-item scale. 5-6 statements represent each of the 6 elements of the operational definition of transaction. The ATS originally consisted of 58 items with a Cronbach’s alpha of .83 and a content validity index of .82. The ATS was revised based on recommendations of content experts, King, and an instrumentation expert to the current ATS of 32 items. CVI of the revised ATS is .774. The design was a nonexperimental descriptive comparative study. The subjects included a convenience sample of 49 adolescents, 12-15 years old in two different settings. The “chronic” group consisted of fourteen subjects were from an outpatient hematology/oncology clinic of a large metropolitan children’s hospital. The “well” group was 35 adolescents in ninth grade science classes in a large suburban high school. Demographic data was collected to determine eligibility and presence of a health problem and number of visits to a health care provider (HCP) over the past year. Both groups were given the ATS. Reliability was determined using Cronbach’s alpha using the entire sample. The mean of the score of the ATS for each group was compared to determine the ability of the ATS to discriminate between two groups. Findings showed a Cronbach’s alpha of .93 for the revised ATS and that it was able to discriminate between the two groups. The ATS scores were significantly higher in adolescents in the chronic group than in the well group (one-tailed t-test, p=.0315, df=47). It also showed that the chronic group had significantly more visits to a HCP than the well group (one-tailed t-test, p=.0015, df=14.85). Construct validity will be tested in the main study by doing a factor analysis using principal axis factoring with orthogonal varimax rotation. Reliability will be determined by calculating a Cronbach’s alpha. Subjects will be 14-17 years old. Adolescents with increased opportunity to interact with HCP had higher scores, but the means were still very low indicating a need to improve communication. Using a focused interview technique based on the operational definition of transaction in every encounter with adolescents to involve them in the goal setting should improve communication and have a positive effect on health outcomes.
