 During the pilot phase, 10 women will be asked to participate in an initial intake appointment to sign the informed consent form, complete baseline questionnaires, receive an activity monitor, and receive instructions on completing the daily surveys and wearing the activity monitor. Women will also be asked to provide their typical daily wake times and bedtimes during this appointment to guide the sampling schedule. Ecological momentary assessment EMA in which women receive two or three daily prompts to complete a short survey will be used in this study. Women will be asked to answer seven questions assessing their momentary activity 1, self-efficacy 1, and self-worth 5 twice per day for one week and three times per day for one week. Five women will be assigned to each condition each week so that half of the sample receives the twice per day condition during the first week and half receives the twice per day condition during the second week of the pilot phase. Women sampled twice per day will be prompted to complete assessments 1 15 minutes after their typical wake time reported during their intake appointment and 2 90 minutes prior to their typical bedtime. Women sampled three times per day will be prompted one additional time during the afternoon random time between 2:00 and 3:00pm. Women will be prompted to complete the survey via text message. A link will be provided in each text message to direct women to a mobile compatible Qualtrics survey containing seven items assessing womens current activity, self-efficacy, general self-worth, knowledge self-worth, emotional self-worth, social self-worth, and physical self-worth. At the end of the two week pilot phase, women will be asked to complete a survey to provide feedback on the sampling scheme and the usability of the mobile survey. Results of the survey will inform modifications to the test phase.
