Filter by:The goal of this randomized clinical trial is to evaluate the efficacy of trauma-adapted yoga as a complementary intervention to care as usual in child and adolescents psychiatry clinics, in the population of adolescents with the diagnosis of ADHD and/or PTSD. We hypothesize that trauma-adapted yoga (TAY) is an effective non-pharmacological intervention for adolescent with ADHD and/or PTSD. Aims: (1) Validate the impact of TAY on the mental health & quality of life of adolescents with ADHD and/or PTSD. (2) Investigate the feasibility of online TAY for continued self-care. (3) Explore adolescents' experiences & parental perspectives on TAY in their treatment. (4) Explore healthcare professionals' experience on the integration of TAY into clinical practice. Within and between group (yoga group vs waiting list) analyses will be performed.
The main objective of the study is to evaluate the influence of caffeine intake on participants' energetic arousal, affect, motivation to achieve a training goal, satisfaction with training, and the sense of agency during training. Consequently, participants will engage in three sessions: caffeine, placebo, and no substance (in counterbalanced order). During each session, their affective and motivational states will be assessed, along with the performance of a standardized physical exercise test. The investigators hypothesize that participants who consume caffeine (caffeine condition) will exhibit higher levels of energy and motivation compared to the other two groups. Additionally, they are expected to experience greater optimism and expectancy regarding their training goals and achieve better results in the physical exercise test. A secondary aim of the study is to examine the impact of genetic variability on motivational and affective states of participants, as well as their performance in the physical exercise test after caffeine. The investigators will assess the CYP1A2 (-163C > A, rs762551; characterized such as "fast" (AA genotype) and "slow" caffeine metabolizers (C-carriers)) and ADORA2A (1976T > C; rs5751876; characterized by "high" (TT genotype) or "low" sensitivity to caffeine (C-carriers)).
The goal of this randomized controlled trial is to examine the effects of a walking intervention (3 walks per week for a period of 4 weeks) in a nature vs. urban setting on the wellbeing of young adult postsecondary students. We will examine changes in positive and negative affect for participants assigned to the nature condition vs those assigned to the urban condition (primary outcome). We will also examine changes in reported depression and anxiety symptoms, perceived stress levels, sleep quality, mindfulness and wellbeing (secondary outcome).
This study aims to investigate whether consuming a drink containing powdered blueberries (equivalent to 150 g of fresh fruit) can improve mood and executive function in healthy emerging adults.
The goal of this clinical trial is to test if a mindfulness-enhanced positive affect induction (MPAI) works well to reduce pain intensity and pain unpleasantness from a cold water pain test in undergraduate college students who do not endorse ongoing medical or mental health diagnoses. The main questions it aims to answer are: - Is the MPAI a feasible and acceptable psychological technique for managing brief pain? - Does the MPAI work well to reduce pain intensity and unpleasantness from experimentally induced brief pain, compared to those using a breathing meditation or those instructed to respond naturally. - Does using the MPAI work well to improve confidence in self-managing brief pain? Participants will be asked to complete questionnaires about their sleep, pain beliefs, and emotions after consenting to participate and at the end of the study session. They will then be randomized to either: - Use the MPAI for managing pain induced by a cold water test (placing their hand in a container of cold water kept at approximately 5 degrees Celsius). - Use a breathing meditation for managing pain induced by a cold water test (placing their hand in a container of cold water kept at approximately 5 degrees Celsius). - Respond naturally to pain induced by a cold water test (placing their hand in a container of cold water kept at approximately 5 degrees Celsius). Researchers will compare the MPAI group to the breathing meditation and natural response groups to see if the MPAI group reports less pain from the cold water test and
Posttraumatic stress disorder (PTSD) has devastating health consequences. Evidence-based PTSD interventions address the substantial burden of PTSD on the health of individuals and societies; however, several individuals receiving these interventions drop out and not all individuals experience improvement in PTSD symptoms. Moreover, these current PTSD interventions primarily target trauma memories. Notably, growing evidence suggests that PTSD symptoms are related to difficulties in the encoding and retrieving of positive memories as well. Thus, the proposed study will examine effects of and targets underlying a novel PTSD technique focused on narrating and detailing positive memories - Processing of Positive Memories Technique (PPMT). Methodologically, 70 individuals will be randomly assigned to PPMT vs. Supportive Counseling (SC) for this study. The aims of the proposed study include (1) examining PPMT's effects on PTSD symptom severity and stress systems' dysregulation (i.e., awakening salivary alpha amylase [sAA] and cortisol); (2) examining mechanisms underlying PPMT's effects; and (3) refining PPMT. It is hypothesized that the PPMT arm will report greater decreases in PTSD severity and sAA/cortisol ratios. Further, it is hypothesized that PPMT-related improved affect will mediate the association between study arm (PPMT vs. SC) and changes in PTSD severity. Lastly, feedback will be obtained from study participants on PPMT's feasibility, format, and content to refine PPMT. The proposed study may contribute preliminary evidence on the potential significance of targeting positive memories in PTSD interventions.
Researchers at the University of North Carolina at Greensboro conduct a single-arm intervention trial to investigate the efficacy of a music-based group exercise program for community-dwelling older adults. Up to forty participants will be recruited to participate in a music-based light-to-moderate intensity group exercise program for 20 weeks (30 - 40 min/day, up to 6 days/week), which is designed for older adults with or without functional limitations to exercise with chairs for the improvement of aerobic capacity, upper and lower body strength, and balance control at a gradually increasing pace. During the exercise sessions, participants will be trained to move in time with music playlists in synchronous tempos. Primary outcomes are cognitive performance, mobility, and health-related quality of life measured before and after the intervention. Secondary outcomes are adherence to the exercise program as a potential mediator of the treatment.
The athlete population has a high risk of suffering from mental health problems (e.g., anxiety), especially for athletes with individual sports. As such, various forms of mental training were used to maintain the mental health of athletes, such as mindfulness training or relaxation training. However, differences pertaining to the electrophysiological mechanisms resulting from both mental training in athletes are unknown. Therefore, the purpose of the current study was to examine the differential effects between the brief mindfulness induction (MI) and relaxation induction (RI) on state anxiety, affect and the activation of the brain in track and field athletes.
A call for an exercise prescription aiming at pleasure promotion has been proposed by several authors. This entails that current exercise prescription guidelines are heavily focused on a dose-response relation derived from an effectiveness (e.g., fitness gains) and safety of the prescription (e.g., reduced risk of injury for the general population) standpoint. Despite its relevance, this bipartite or biomedical approach (e.g., rationale for a given dose of a drug and expected outcome) tends to overlook other relevant variables that are needed for, for example, behavior maintenance, or individual preferences. Although some flexibility of this rationale may account for personal differences, how to adequately adjust the training variables to individual characteristics is still poorly explored or even expressed. The call for a tripartite exercise prescription reflects the bout of evidence that supports the relevance of pleasurable experiences in exercise and their impact on adherence. Thus, besides an effective and safe program, contemplating how to assess and promote exercise-related pleasurable experiences are paramount. As stated in 2011 on the ACSM position stand, affect-regulation did not behold the necessary evidence to be a primary method of exercise prescription, although affect assessment (e.g., through the feeling scale) was proposed to be relevant for exercise intensity self-regulation. A decennial look at the ACSM exercise guidelines shows that although presenting an advancement in affect-related behavioral strategies and theories, no clear indications on operational instruments for assessment and admeasurement of affect are presented depicts a barrier to an adequate advancement in this matter. This can be seen, for example, in ACSM principles for exercise prescription (Frequency, Intensity, Time, and Type; FITT). Although supporting the use of affect regulation for exercise promotion and maintenance, the FITT is not based on a previous (e.g., preexercise evaluation) or in-session affective assessment, and more importantly, does not address how to adjust exercise prescription/supervision aiming to improve the pleasure/displeasure relation.
This randomized controlled trial will assess the effects of External Cues focused messaging (i.e., government recommendations of MyPlate) compared to Internal Cues focused messaging (i.e., intuitive eating). The investigators will collect data on within-person changes in psychological (e.g. affect) and physiological (e.g. heart rate variability) outcomes in female college students. Participants will be randomly assigned to one of two study conditions. In condition one, participants will view a five-minute video focusing on traditional nutrition education principles. In condition two, participants will view a five-minute video focusing on intuitive eating principles.
