The purpose of this study is to examine whether an integrative group-based intervention will help children experiencing psychological and physical distress. Children, ages 10 to 12, will be recruited for participation in this therapeutic group. Eligible and consenting participants will be randomized to a wait-list control group or the group intervention. The group intervention will take place over a 12-week period, during which participants will attend a weekly coping skills group that integrates yoga-based practices (such as yoga poses, mindfulness, self-acceptance, breath work) with cognitive-behavioral principles (such as increasing awareness of thoughts and emotions).

Psychosomatic symptoms are physical complaints in the absence of an organic cause. For children and adolescents, psychosomatic symptoms often manifest as headaches, gastrointestinal (GI) discomfort, non-specific musculoskeletal pain, and fatigue. These symptoms are strongly associated with the presence of an internalizing disorder-namely, anxiety or depression-in youth. Thus, treatment of these symptoms has often been cached within a broader intervention protocol, the overarching goal of which is to address the global internalizing disorder. For children who experience intense and persistent psychosomatic discomfort, however, it can be critical to specifically target these symptoms through intensive intervention. Otherwise, psychosomatic complaints can be extremely impairing, impeding children's attendance in school, participation in extracurricular activities, and disrupting family activities. At present, there are few systematic that can target a range of psychosomatic problems.

Yoga-based interventions may be a particularly valuable treatment for children with psychosomatic complaints. Such interventions have been studied empirically in adults with a number of psychosomatic conditions, and more recently in children with a variety of psychological conditions. Indeed, there have been a small number of studies targeting psychosomatic complaints in children via yogic practices. Although there is emerging interest in yoga-based interventions for youth, and slowly growing evidence their efficacy, at present there are no known structured interventions for youth with psychosomatic complaints in the context of an internalizing disorder. Thus, the goal of the present proposal is to develop a semi-structured, manualized intervention that targets impairing psychosomatic symptoms in youth with a comorbid internalizing disorders. The specific aims are as follows:

Specific Aim 1 Treatment Feasibility: Assess the feasibility of a novel integrative coping intervention for children with somatic symptoms and anxiety.

Hypothesis: The yoga-based intervention will be acceptable and feasible for children. Acceptability will be defined as a 50% consent rate among participants approached for the study; Feasibility will be defined by 75% of children completing 80% of intervention sessions.

Secondary Aim 1 Treatment Efficacy: Assess the preliminary efficacy of a 12-week integrative coping intervention on both somatic and psychological (e.g., anxiety, mood) symptoms compared to a wait-list control condition.

Hypothesis: Children in the active intervention condition will have a significant reduction in somatic and anxiety symptoms following the 12-week intervention compared to a wait-list control.

Inclusion Criteria:

1. Children between the ages of 10- and 12-years old;

2. Presence of clinically-relevant internalizing symptoms (e.g., anxiety or depression) as defined by any of the following:

   3. Current medical intervention for somatic pain in the absence of an organic disease (e.g., medical treatment for migraines or irritable bowel syndrome)

Exclusion Criteria:
