Self-compassion Therapist-led Online Group Treatment for Adolescents With Distress, Anxiety, and Depression

Adolescence is a vulnerable period of growth and challenges, characterized by rapid physiological and emotional changes. All these changes happen at the same time as relationships expand. A developing self together with a pressure to "fit in" can lead to self-critic and distress. Without appropriate coping skills to manage these challenges, adolescents are more vulnerable to psychological problems. Distress, anxiety, and depression have also increased in the western world during the last years, and especially girls or young women are affected [1]. In addition, depressive disorders are the single largest contributor to global disability [2]. Adolescents-appropriate training in compassion may help adolescents successfully overcome the challenges in the future and help adolescents to take care of themselves.

Schools are not just about acquiring knowledge, they are playing a central role in cultivating necessary social, emotional, and ethical skills required to lead successful lives [3]. Recently, there has been a great interest in bringing mindfulness and compassion to educators and students.

The construct of compassion is defined by Paul Gilbert as a "sensitivity to suffering in self and others with a commitment to try to alleviate and prevent it" [4] and include compassion for oneself, compassion for others, and receiving compassion from others. Compassion strategies are core competencies in life, already taught by large religions as Christianity and Buddhism, but now in a modern version along with new neurobiological research and cognitive behavior therapy interventions. These skills or strategies can be taught, but have not yet been widely used in the contexts of adolescents [3].

Research supporting compassion focused therapy for depression Compassion focused therapy (CFT) was developed two decades ago and is a well-established talking therapy for depression and stress [5]. Compassion has a protective effect against depression and suicidality [6], in youth. Training in compassion is linked to well-being and perceived life satisfaction [7]. Meta-analytic findings of CFT on adults has recently showed moderate effects on stress, depression and anxiety [7]. Studies with adolescents are few. For example one small study [8] with 34 14-17 year old students found that a mindful self-compassion school program in six weeks was feasible and acceptable. The intervention group had significantly greater self-compassion and less depression than the waitlist control.

The CFT intervention Compassion Focused Training (CFT). The investigators have developed a new manual for CFT training with seven modules [9] including 1) what is compassion, 2) understanding myself, 3) life-compass, 4) self-compassion and my body, 5) feelings and compassion, 6) create balanced thoughts, and 7) imagination. CFT is an internet-delivered (zoom or teams) real time group training (for 15-20 years old adolescents), 1,5h, in seven weeks. The youth will receive a manual for practice. The investigators were inspired by Professor Paul Gilbert, Mary Welford, and Elaine Beaumont's approach [10], but the investigators have shortened and adapted Welford and Beaumont manual to Swedish context. In addition, the investigators are influenced by cognitive behavior principles. Functional analyses and thoughts records are for example, used. The intervention focuses on the present and not on processing memories. The intervention is made for primary care and school health. A psychotherapist/psychologist or social worker will lead the training.

Theory behind the studies Compassion focused therapy is a components-based approach that integrates evolutionary theory, neurobiology, attachment theory, affect theory, family theory, cognitive behavioral principles, and humanistic theory [4].

The originality of the project Even though CFT has shown good results for adults, there are only a few small CFT studies on adolescents. None of them provide internet-delivered therapy. Our short internet-delivered group intervention for youths will be unique and could possibly be a good preventive and healing intervention for schools. Primary care and school health care need more efficient methods for both preventing and treating distress, anxiety, and depression.

Many barriers limit treatment uptake, such as limited number of trained therapists, costs, compliance issues such as time off work, and transportation, associated with the need to attend weekly appointments [11]. Delivering CFT in groups on the internet may be an effective and acceptable alternative to therapist-delivered treatment in primary care and at school health care. especially for rural areas.

Internet delivered such as telehealth, minimize barriers in access to care and address health-care disparities. Furthermore, internet delivered therapy allows for culturally and linguistically competent providers to offer mental health services to adolescents who might not have access to such clinicians in their communities. Nevertheless, several challenges have been identified in the literature including technological issues (e.g., poor internet connection), privacy and confidentiality (e.g. finding a quiet and private location), and safety concerns [12,11]. More and better studies with more modern technology are needed to develop this further.

A quality assurance data plan has been written. The investigators will collect quantitative data through RED Cap, which is a web survey recommended by Umeå University [13]. Data from RED Cap is saved at Umeå University. Only anonymous data with code will be saved at RED Cap.

Multifactor authentication is required for logging in to "protective documents" at Umeå University, and also for RED Cap, Outlook, TEAMS and other O365 system. The investigators are storing sensitive data on Umeå University system for that: protective documents [14].

The investigators are following Swedish archive laws and are using a Umeå University system for that [15].

The investigators will do data checks to compare raw data over time if data quality is sustained. Check sum will be used for this.

A data dictionary that contains detailed descriptions of each variable used by the registry, including the source of the variable, and coding information if used and normal ranges if relevant, will be performed.

Standard Operating Procedures have been written to address registry operations and analysis activities, such as patient recruitment, data collection, data management, data analysis, reporting for adverse events, and change management.

Data calculations To address outcomes, data will be screened for faulty values and dependent variables will be examined for normality.

Randomization exclude systematic differences between groups (CFT group (n=20) and control group (n=20, waitlist)) at baseline, so the investigators will only calculate differences in effect sizes (Hedge g and Cohens d) on baseline demographic and psychosocial variables.

Descriptive statistics will be calculated for CFT group and control group for pre- and post-intervention.

To assess whether the groups (CFT group and control group) differ on post values, the investigators will conduct three Ancovas controlling for baseline. Dependent variables: posttest of total score of Perceived Stress Scale, subscale anxiety and depression in Trauma Symptom Checklist for Children (TSCC). Independent variable: Groups (CFT group and control group). Controlling variables: pretest of total score of total score of Perceived Stress Scale, subscale anxiety and depression in Trauma Symptom Checklist for Children (TSCC).

The investigators will calculate Hedges' g scores for effect size of differences between groups. Hedges' g is similar to Cohen's d, but includes a correction factor for small samples. Nonsignificant differences with Hedges' g greater than .20 are considered meaningful and are interpreted according to convention: .20=small, .50=medium, .80=large.

Finally, several Ancovas will be conducted to examine whether differences between CFT group and control group changes in secondary outcomes were found.

The investigators will use an exploratory approach for not missing any changes and the significance level will be 0.05. This study will be underpowered, and the outcome will be used to calculate power for a larger RCT-study. The investigators will both calculate result for intention to treat and for those who have participated more than two times.

Within-participant change will be calculated with Reliable Change Index [16].
