Physical activity, mindfulness meditation, or heart rate variability biofeedback for stress reduction: a randomized controlled trial

In contemporary western societies stress is highly prevalent, therefore the need for stress-reducing methods is great. This randomized controlled trial compared the efficacy of self-help physical activity (PA), mindfulness meditation (MM), and heart rate variability biofeedback (HRV-BF) in reducing stress and its related symptoms. We randomly allocated 126 participants to PA, MM, or HRV-BF upon enrollment, of whom 76 agreed to participate. The interventions consisted of psycho-education and an introduction to the specific intervention techniques and 5 weeks of daily exercises at home. The PA exercises consisted of a vigorous-intensity activity of free choice. The MM exercises consisted of guided mindfulness meditation. The HRV-BF exercises consisted of slow breathing with a heart rate variability biofeedback device. Participants received daily reminders for their exercises and were contacted weekly to monitor their progress. They completed questionnaires prior to, directly after, and 6 weeks after the intervention. Results indicated an overall beneficial effect consisting of reduced stress, anxiety and depressive symptoms, and improved psychological well-being and sleep quality. No significant between-intervention effect was found, suggesting that PA, MM, and HRV-BF are equally effective in reducing stress and its related symptoms. These self-help interventions provide easily accessible help for people with stress complaints

Parenting, family functioning and anxiety-disordered children: Comparisons to controls, changes after family versus child CBT

We examined (1) whether families of clinic-referred anxiety-disordered children are characterized by anxiety-enhancing parenting and family functioning, compared to control families; (2) whether family cognitive-behavioral therapy (FCBT) for anxiety-disordered children decreases anxiety-enhancing parenting and family functioning more so than child-focused cognitive-behavioral therapy (CCBT); (3) whether anxiety-disordered children benefit more from therapy in the long-term when parents display less anxiety enhancing parenting and family functioning. The referred sample consisted of 104 anxiety-disordered children (8-18 year-olds) and their families, randomized to FCBT or CCBT. The control sample consisted of 44 families from the general population. At pretreatment (referred and control sample), posttreatment, 3-months and 1-year follow up (referred sample), children’s anxiety disorders were assessed by the ADIS-C/P. Child and parents’ anxiety symptoms, parenting behaviors (autonomy granting, overprotection, rejection) and family functioning (relational functioning, family control) were assessed with questionnaires. Parent-reported autonomy granting and family relational functioning were lower in the referred versus control families. Child-reported autonomy granting was higher in the referred families. Anxiety-enhancing parenting/family functioning decreased after FCBT and CCBT, with no differences between treatments. Good family relational functioning at posttreatment predicted more improvement on anxiety measurements at the long term for adolescents, but not for school-aged children. The generally hold idea that certain parenting styles and family functioning cause child anxiety, and need to be specifically targeted in the treatment of anxious children, is not supported. Good relational functioning within adolescent’s families however is associated with better long-term outcome on anxiety, suggesting that families can support the maintenance of treatment gains
