This study will help to (1) assess whether values clarification leads to increased motivation to engage in physical activity, greater stability in motivation, and improvements in engagement in physical activity and valued action, relative to engaging in self-reflection, (2) determine if the impact of values clarification on these outcomes vary depending on context (e.g., positive/negative affect, psychological inflexibility, stressful events), (3) explore whether values clarification procedures that employ distinct relational frames (hierarchical, conditional, distinction, and deictic) differentially impact motivation to engage in physical activity, and daily engagement in physical activity, and (4) explore whether the impact of values clarification vary depending on baseline self-compassion and/or intrinsic/extrinsic motivation., conditionsModule conditions: Health-Related Behavior, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, primaryPurpose: TREATMENT, maskingInfo masking: NONE, enrollmentInfo count: 64, type: ESTIMATED, armsInterventionsModule interventions name: Values Clarification Mobile Application, interventions name: Self-Reflection Mobile Application, outcomesModule primaryOutcomes measure: International Physical Activity Questionnaire (IPAQ) - Total physical activity, secondaryOutcomes measure: Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3) - Total score, secondaryOutcomes measure: Amotivation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3), secondaryOutcomes measure: External Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3), secondaryOutcomes measure: Introjected Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3), secondaryOutcomes measure: Identified Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3), secondaryOutcomes measure: Integrated Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3), secondaryOutcomes measure: Intrinsic Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3), secondaryOutcomes measure: Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Questionnaire v1.2, secondaryOutcomes measure: Global Mental Health - Subscale of the PROMIS Global Health Questionnaire v1.2 (Patient-Reported Outcomes Measurement Information System), secondaryOutcomes measure: Global Physical Health - Subscale of the PROMIS Global Health Questionnaire v1.2 (Patient-Reported Outcomes Measurement Information System), secondaryOutcomes measure: Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form v2.0 - Satisfaction with Social Roles and Activities 8a, secondaryOutcomes measure: Multidimensional Psychological Flexibility Inventory - Short Form 24-item version (MPFI-24), secondaryOutcomes measure: Contact With Values - Subscale of the Multidimensional Psychological Flexibility Inventory - Short Form 24-item version (MPFI-24), secondaryOutcomes measure: Lack of Contact With Values - Subscale of the Multidimensional Psychological Flexibility Inventory - Short Form 24-item version (MPFI-24), secondaryOutcomes measure: Values Clarity Questionnaire (VCQ), secondaryOutcomes measure: Self-Compassion Scale Short Form (SCS-SF), secondaryOutcomes measure: Random responding question, secondaryOutcomes measure: Credibility & Expectancy Questionnaire (CEQ), secondaryOutcomes measure: System Usability Scale (SUS), secondaryOutcomes measure: Treatment Evaluation Inventory-Short Form (TEI-SF), secondaryOutcomes measure: Exercise ecological momentary assessment (EMA) questions, secondaryOutcomes measure: Multidimensional Psychological Flexibility Inventory - Short Form 24-item version adapted for ecological momentary assessment (MPFI-24 validated for EMA), secondaryOutcomes measure: Momentary Contact With Values - Subscale of the Multidimensional Psychological Flexibility Inventory - Short Form 24-item version adapted for ecological momentary assessment (MPFI-24 validated for EMA), secondaryOutcomes measure: Momentary Lack of Contact With Values - Subscale of the Multidimensional Psychological Flexibility Inventory - Short Form 24-item version adapted for ecological momentary assessment (MPFI-24 validated for EMA), secondaryOutcomes measure: Emotion ratings, secondaryOutcomes measure: Current Motivation to Exercise, secondaryOutcomes measure: Previous Day Stress Level, eligibilityModule sex: ALL, minimumAge: 18 Years, maximumAge: 65 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Mindfulness and Acceptance Processes Lab, city: Starkville, state: Mississippi, zip: 39759, country: United States, geoPoint lat: 33.45049, lon: -88.81961, hasResults: False
