Engagement in health promoting behaviors will be assessed using the Health Behavior Survey (HBS). This measure is composed of the 30-item Health Behavior Survey (HBS) that was developed for a previous study (Hocking, Schwartz, Hobbie et al., 2013). HBS alcoholic beverage consumption (4-items), smoking (2-items), other drug use (4-items), sunscreen use (1-item), health-screening (1-item), exercise (4-items), sexual behavior (3-items), and nutrition/weight (7-items). These items will be scored as either health promoting or health limiting (1 point for each health promoting behavior). The total score, as well as scores from each content area, will be used.

Perceived Health Competence Scale (PHCS) survey will be used to assess health competence beliefs. The survey is an 8-item instrument designed to assess perceived effectiveness carrying out health behaviors and influencing personal health outcomes. Participants rate each item on a 5-point Likert scale, from strongly disagree to strongly agree. Items yield a total score.

Minneapolis-Manchester Quality of Life Instrument-adolescent (MMQL) survey will be used to measure health related quality of life in adolescent and young adult survivors of childhood cancer by assessing physical functioning, psychological functioning, social functioning, cognitive functioning, body image, outlook on life, and intimate relationships. Scores range from one to five, with a higher score indicating a better HRQL An overall QoL score is reached by finding the mean score for all the items.

Medical record review as well as completion of the Medical Adherence Measure (MAM) survey will be used to assess patient adherence to clinic attendance. The MAM assesses adherence. Patient adherence to medication and to clinic attendance are each rated on a 10-point scale (1 = never; 10 = always take medication). Participants also select barriers to adherence from a list of 12 and the option to write in another reason.

Knowledge of health promoting behaviors will be assessed using the Knowledge Acquisition Measure questionnaire. The measure was developed by the research team for use in this study. The questionnaire consists of 23 multiple choice items regarding knowledge of basic health-promoting behaviors (e.g. recommended sunscreen use and maintenance of physical health) as well as five goal-specific questions that each participant will answer based on the goal he or she chose at the time of enrollment. All components of the Knowledge Acquisition Measure aim to assess the amount of health-related knowledge gained over the course of the intervention.

Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQUI) questionnaire- 19-item self-report questionnaire that measures subjective sleep quality and disturbance in adults over the past one-month period and discriminates "good" and "poor" sleepers (Buysse, Reynolds, Monk, Berman, & Kupfer, 1989). The PSQI yields a global score (PSQI-G) and seven subscale scores consisting of Sleep Quality, Sleep Latency, Sleep Duration, Sleep Efficiency, Sleep Disturbances, Sleep Medications, and Daytime Dysfunction, with a global score of > 5 thought to be suggestive of significant sleep disturbance.

Medical adherence will be assessed by medical record review as well as Medical Adherence Measure (MAM) - Patient adherence to medication and to clinic attendance are each rated on a 10-point scale (1 = never; 10 = always take medication). Participants also select barriers to adherence from a list of 12 and the option to write in another reason.

Multidimensional fatigues scale (MFS) questionnaire will be used to assess fatigue. The measure is an 18- item questionnaire that yields a total score and three subscale scores: General Fatigue, Sleep/Rest Fatigue, and Cognitive Fatigue. Items are answered on a 5-point Likert-type scale indicating how problematic each element of fatigue was over the past month. Lower scores indicate more fatigue

Goal Attainment Measure - was developed for this study, and assesses participants' expectation of (10-items) and progress related to achieving their chosen goal (9-items).
