Clinical Trial Summary
Prevalence of mental health problems and disorders in children and adolescents (hereafter
youths) are estimated at 13.4% of which anxiety and depressive disorders account for more
than half of these disorders. These rates are increasing, putting a large strain on child and
adolescent mental healthcare services (CAMHS) to provide cost-effective treatments with
documented long-term effects. However, even when provided the best evidence based treatment,
between 40-50 % do not recover and continue to report significant symptom burdens. Thus,
there is an immediate need for supplementary and/or new treatment approaches. Physical
activity as a supplementary treatment may be one such approach. However, research
investigating this approach within this population is scant. This protocol paper describes
the development and feasibility trial of a physical activity based intervention targeting
anxiety and depressive symptoms in youth.
The current study will be based on the UK Medical Council Research Framework (MRC) for
developing and evaluating complex interventions. The study will initially focus on the first
two phases of the MRC framework. In line with phase one of this framework, key intervention
components have been identified in preliminary work, which draw on the effects of moderate to
vigorous physical activity, inhibitory learning theory and self determination theory. These
components are to be developed into an intervention to be used in CAMHS. Twenty youths with
anxiety and/or depressive symptoms will be recruited to the intervention. Physical activity
will be measured using the Actigraph GT3X+ monitor at baseline and post-intervention. Outcome
measures concerning symptom change will be assessed (anxiety and depression). Semi-structured
qualitative interview with participants, caregivers and referring specialists will help
identify possible contextual and practical factors associated with delivery of the
intervention and explore acceptability of assessment procedures, the intervention, and
perceived benefits and barriers to participation.
This study will contribute to the development of evidence-based, patient-informed
supplementary physical treatment interventions for youth with internalizing disorders in
contact with CAMHS. The goal is to examine new avenues of treatment that ultimately may
improve upon current treatment outcomes of these disorders.
Description:
In order for health authorities to be able to respond to the current high demand on mental
health services in youth, current treatment interventions need to be examined. The need for
augmented and/or supplementary interventions is pressing. Physical activity appears to be a
promising, low-risk intervention that may serve this purpose and provide long-term protective
health benefits. Despite the potential gain from including physical activity in CAMHS
treatments, to our knowledge, no previous study has examined the use of a physical activity
program in CAMHS as a supplementary treatment in youth's with anxiety and/or depression.
Furthermore, there is a paucity of studies of high methodologically quality examining this
topic.
It is the aim of the current study to address this shortcoming by developing a theoretically
based physical activity intervention to supplement existing treatment for youth with
internalizing disorders (Confident, Active and Happy Youth: CAH-Y).
The current research and intervention development will be based on the UK Medical Council
Research Framework (MRC) for developing and evaluating complex interventions.
The MRC framework strongly recommends carrying out feasibility testing prior to any
full-scale trial. In line with this recommendation and phases, one and two of the MRC
framework, this study proposes to develop and examine the feasibility of recruitment,
retention and acceptability of a physical activity intervention for youth with anxiety and/or
depression treated in CAMHS. This work will lay the groundwork for later phases and a
definitive RCT.
Methods Development of the intervention The theoretical framework for the CAH-Y intervention
will draw on three theories. While not a unified theory, the evidence on the
psycho-physiological effect of moderate to vigorous physical activity in regards to mood and
anxiety disorders in youth specifically and youth mental health in general, indicates a
plethora of causal pathways and positive effects. Primarily modulation of monoamines (e.g.,
increase in serotonin levels), and HPA axis regulation are assumed to be of importance in
relation to anxiety and depression. Secondly, Self Determination Theory is a framework with
which to understand participant experiences with physical activity and their motivation
towards physical activity. The framework focuses on intervention components that can enhance
learning and intrinsic motivation concerning both increased activity and behaviour and
symptom change. Regarding motivation, evidence suggests that in order to establish physical
activity behaviour change, individuals must be either in the 'preparation' or in the
beginnings of an 'action' stage of change. Thus, in order to increase physical activity, it
is critical that participants are engaged and ready to change behaviour. The final
theoretical foundation is inhibitory learning theory which provides a generic framework to
understand the bi-directional interaction between cognition, affects and behaviour in regards
to anxiety and depression and in particular the role of (physical activity) avoidance as a
contributor to and a maintaining factor in these disorders.
Drawing on evidence from CBT treatment for youths with anxiety disorders, evidence suggests
that group treatment is equally as effective as individual treatment in CAMHS populations.
Furthermore, group treatment provides a number of benefits compared to individual treatment
with the current patient group that render this format superior.
Feasibility testing of the intervention Once the CAH-Y intervention is developed a
feasibility, study will be conducted with the goal of investigating intervention feasibility,
appropriateness and practicality of the designed intervention in the proposed setting, and
appropriateness of the assessments. In addition, as noted in the study aims, an effect size
will be estimated for a subsequent randomized controlled trial based on previous literature
(MRC - Phase 3). The feasibility study is a single arm, non-randomized pre-post control
study.
The CAH-Y intervention will be part of the treatment package available to youth in contact
with child and adolescent mental health services (CAMHS), Haukeland University Hospital. The
CAH-Y intervention is organized within the CAMHS context and will be delivered by personnel
employed in this organization. CAMHS is organized at the same intervention level as ordinary
hospital services (Haukeland University Hospital, Bergen, Norway) and is as such a tertiary
specialized service. In the Norwegian context, this is the primary source of treatment for
youth with mental health disorders.
Study population and eligibility Youth are referred to the treatment program from their
attending psychiatrist or psychologist at the local CAMHS.
Recruitment
Youth will be recruited from CAMHS, Department of Child and Adolescent Psychiatry, Haukeland
University Hospital, Norway. Given that CAH-Y is organized within CAMHS, this enables easy
access to potential participants and streamlined recruitment strategies. In practice, this
translates into:
- uncomplicated dispersion of information regarding the intervention to the departments
and mental health professionals via intranet, email and/or physical/digital meetings
- ease of implementing an in-house digital referral system
- a low threshold for communication between the CAH-Y team and the referring specialist
Consent Written consent is obtained from parents and the children. The regional ethical
committee has approved the feasibility study (REK NR. 30912).
Feasibility procedures After referral to CAH-Y and assessment of eligibility, eligible youth
and their primary caregivers are invited to attend a recruitment and inclusion interview.
This interview will take place in the CAH-Y facilities, and the interview will serve several
purposes. In the interview, therapists will provide further information about the
intervention and study details, clarifying any questions and/or concerns, obtaining written
consent and therapists collect and check the questionnaires included in the invitation for
the recruitment interview. Moreover, additional questionnaires will be filled out (see
primary and secondary outcome measures section), medical information gathered (height and
weight), participants will be provided an Actigraph activity monitor to be worn the next
seven days and an activity diary to fill out. In addition, a short qualitative interview
exploring participant and caregiver views on physical activity will be conducted. Finally,
the youth and caregivers will be given a tour of the CAH-Y facilities in order to familiarize
them with the setting.
The next contact with the youth will be the first session of the CAH-Y program, which will be
between one to a maximum of three weeks after the recruitment and inclusion interview. At
this point, participants will also return the Actigraph monitors and activity diaries. The
intervention then progresses bi-weekly the next seven weeks. The day before every session,
the participants will receive a SMS reminder of the session, as well as a link to the website
explaining the program for this the particular session. This is in order to remind the
participants of the session clarify what is expected and encourage participation.
Following the last session of the intervention, participants will receive an invitation to
attend a post-intervention interview, one to a maximum of three weeks following last
intervention session. In this interview, questionnaires relating to symptom change will be
completed, biometric data will be gathered and a short qualitative interview exploring the
views of the participant and his/her caregivers in relation to the intervention will be done.
At the end of the interview, participants will be provided an Actigraph activity monitor to
be worn for the next seven days and a complementing activity diary. After these seven days
have elapsed, a research assistant will gather the Actigraph. Independently of this
assessment with the participant, a short qualitative interview with the referring specialist
will also be conducted by the PI.
At six months post-intervention, the participants and their caregivers will be invited to
attend a follow-up interview. In this interview, questionnaires relating to initial symptoms
will be filled out anew, and a new short qualitative interview exploring views possible
negative and/or positive effects of the intervention will be done. It the end of the
interview, participants will be provided an Actigraph activity monitor to be worn for the
next seven days and a complementing activity diary. After this time-period, the Actigraph
will gathered by a research assistant.
Comparison group In the feasibility study in phase 2, no comparison group will participate.
Participants will serve as their own controls. Pre- and post-treatment results will be
compared.
Measures Apart from the measures that participants and their caregivers fill out at home, all
other measures and assessments will be conducted in the CAH-Y facilities.
Socio-demographic characteristics and psychiatric conditions Feasibility outcomes
Participant-centered outcome measures. Timing Measures will be assessed at baseline
(pre-intervention interview) and at the latest two weeks after completing the intervention in
phase 2. Follow-up outcome will be assessed six months post-intervention.
Sample size As this will be the feasibility study to inform the design of the future
definitive RCT, a target sample of 20 youth participants will be recruited for estimation of
the intended variables.
Statistics and data analysis Quantitative data will be analyzed using SPSS version 22.0 for
Windows.
Quantitative summaries regarding feasibility data will be presented in tables and will
include:
- number of potential participants referred
- number of participants assessed eligible, and assessed reason for non-eligibility
- attendance and retention rates Baseline data for participants will also be presented in
charts as well as any possible participant missing data (questionnaires and Actigraph).
Descriptive data will use 95% confidence intervals (mean and standard deviations).
Baseline differences between groups (e.g. age, activity level, BMI, number of mental
health disorders and questionnaire outcomes) will be analysed using one-way ANOVA.
Nominal data (e.g. gender, ethnicity, social class, participation in school physical
activity) will be analysed using Chi-square analyses. However, as mentioned the
feasibility study is underpowered to detect any effects reliably. Thus, quantitative
feasibility outcomes will be interpreted only as feasibility and pilot data due to lack
of statistical power.
Qualitative interviews with participants, caregivers and referring specialists will be
analysed utilizing thematic analysis. Accordingly, the written interview data will be
reviewed for data familiarization; initial codes will be generated, followed by organizing
codes into themes, refining themes, and finally defining themes and sub-themes.
