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. conditions: Health-Related Behavior studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL primaryPurpose: TREATMENT masking: NONE count: 64 type: ESTIMATED name: Values Clarification Mobile Application name: Self-Reflection Mobile Application measure: International Physical Activity Questionnaire (IPAQ) - Total physical activity measure: Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3) - Total score measure: Amotivation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3) measure: External Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3) measure: Introjected Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3) measure: Identified Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3) measure: Integrated Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3) measure: Intrinsic Regulation - Subscale of the Behavioral Regulation in Exercise Questionnaire, Version 3 (BREQ-3) measure: Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Questionnaire v1.2 measure: Global Mental Health - Subscale of the PROMIS Global Health Questionnaire v1.2 (Patient-Reported Outcomes Measurement Information System) measure: Global Physical Health - Subscale of the PROMIS Global Health Questionnaire v1.2 (Patient-Reported Outcomes Measurement Information System) measure: Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form v2.0 - Satisfaction with Social Roles and Activities 8a measure: Multidimensional Psychological Flexibility Inventory - Short Form 24-item version (MPFI-24) measure: Contact With Values - Subscale of the Multidimensional Psychological Flexibility Inventory - Short Form 24-item version (MPFI-24) measure: Lack of Contact With Values - Subscale of the Multidimensional Psychological Flexibility Inventory - Short Form 24-item version (MPFI-24) measure: Values Clarity Questionnaire (VCQ) measure: Self-Compassion Scale Short Form (SCS-SF) measure: Random responding question measure: Credibility & Expectancy Questionnaire (CEQ) measure: System Usability Scale (SUS) measure: Treatment Evaluation Inventory-Short Form (TEI-SF) measure: Exercise ecological momentary assessment (EMA) questions measure: Multidimensional Psychological Flexibility Inventory - Short Form 24-item version adapted for ecological momentary assessment (MPFI-24 validated for EMA) 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) 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) measure: Emotion ratings measure: Current Motivation to Exercise measure: Previous Day Stress Level sex: ALL minimumAge: 18 Years maximumAge: 65 Years stdAges: ADULT stdAges: OLDER_ADULT facility: Mindfulness and Acceptance Processes Lab city: Starkville state: Mississippi zip: 39759 country: United States lat: 33.45049 lon: -88.81961 hasResults: False
