Depression Anxiety Disorder Clinical Trial
Official title:
Randomized Control Trial of RESOLVE (Relaxation Exercise, SOLving Problem and cognitiVe Errors): A Waiting Room Intervention for Crisis Clients
Crisis Teams are now a well established part of the mental health system. These teams are effective in providing crisis management, treatment, referral, and educational services. We are testing a waiting room intervention for the patients attending a Crisis Team. As far as we are aware, no trial of a waiting room intervention has been reported in a psychiatric setting. This is a preliminary study using a Randomized Control Trial (RCT) Design. Patients (N =40) will be randomly allocated to either the treatment or the control group, and will be selected from the local Crisis Team. The treatment group will receive a waiting room intervention called, RESOLVE (Relaxation, SOLving problem and cognitiVe Errors), that is a short film, Plus Treatment As Usual (TAU), and the control group will receive only TAU. Patients in both groups will be assessed before and after the intervention, using the HADS (Hospital Anxiety And Depression Scale), CORE (Clinical Outcome in Routine Evaluation), (to measure psychopathology) and WHODAS (World Health Organization Disability Assessment Schedule) (for functioning). We hypothesize that the treatment group will demonstrate significant improvement in mental health and functioning, compared to the control group. Analyses will be conducted using SPSS v22, and will consist of a t-test or Chi Square test to measure the baseline differences, and a linear regression to compare the differences between the two groups at the end of the intervention. Results will be published in international journals and will be presented in local and international conferences.
GRANT APPLICATION The mental health crisis teams are now a well established and vital part
of the mental health system. These teams are uniquely equipped to provide front-line mental
health care when and where it is most needed. It is able to provide on-site assessment,
crisis management, treatment, referral, and educational services to patients, families, law
enforcement officers, and the community at large. Mental health crisis teams provide access
to mental health care for even the most under-served populations efficiently and
cost-effectively. The cost-effectiveness of the team's services is defined by savings in
both monetary and human terms (Zealberg, Santos, & Fisher, 1993) (Scott, 2000). However, no
interventions have been developed, that are specific to this service.
Patients attending the crisis teams usually wait for their appointments, just like other
health settings. This can be a valuable time that can be used to deliver short term
educational interventions. This has been tried and tested in general health settings (Coyne,
Palmer, Shapiro, Thompson, & DeMichele, 2004; Holmes-Garrett, 1990; Oermann, n.d.; Rhodes et
al., 2001; Wheeler et al., 2001). As far as we are aware no waiting room interventions have
been tried or tested in psychiatric setup. We have developed an intervention RESOLVE
(Relaxation Exercise, SOLving problem and cognitiVe Errors), that can be easily delivered
using eMedia (for example a tv screen) in waiting room. This intervention is short enough to
be given while patients are in a waiting room in a psychiatric clinic. A crisis team setting
might be ideal as most patients might find a problem solving approach helpful. We want to
conduct a pilot using a Randomised Controlled Trial design (RCT) to assess effectiveness of
this intervention.
METHODS Objectives The primary objective of this preliminary pilot study is to assess the
effectiveness of a "waiting room intervention" for patients attending a crisis clinic. The
objectives of the study are to see if the intervention can reduce (1) symptoms of depression
and anxiety, (2) overall psychopathology, and (3) disability.
Participants Participants (N =40) will be primarily recruited from the Crisis Clinic in
Kingston. Inclusion criteria are; All those who fulfill the diagnostic criteria of
Depressive episode (F32) or Recurrent depressive disorder (F33 except 33.4 ) using ICD10
RDC, are between the ages of 18 to 65. Patients will be asked to attend a further
appointment at the end of study period and will be assessed again. The exclusion criteria
include; excessive use of alcohol or drugs (using ICD 10 RDC for alcohol or drug abuse or
dependence) significant cognitive impairment (for example learning disability or dementia)
and active psychosis. Data will be kept strictly confidential, available only to the primary
investigators. Participants may withdraw from the study at any time without penalties.
Study design This preliminary evaluation will use a Randomized Control Trial (RCT) design.
Randomization will be performed using www.randomization.com, from the list of all the
patients who consent. Study participants will be randomly assigned to either treatment or
the control arm. The treatment group will receive waiting room intervention plus TAU
(Treatment As Usual), while the control group will receive only TAU. Patients who have been
referred for the study will be provided brief information about the study. Those who meet
the criteria and consent will be then asked to join the study and will be allocated to one
arm of the trial after randomization.
Measurements Demographic information will be collected using a short questionnaire.
Assessments will be carried out by two research assistants independently. We will also
collect data on number of contacts with the Crisis Team, number of admissions and duration
of contact with the Crisis Team.
The Hospital Anxiety and Depression Scale (HADS) (Zigmond and Snaith, 1983) is a 14 item,
self assessment scale designed to measure anxiety and depression. It has a high internal
consistency, face validity and concurrent validity. Even-numbered questions relate to
depression and odd-numbered questions relate to anxiety. Each question has 4 possible
responses. Responses are scored on a scale from 3 to 0. The maximum score is therefore 21
for depression and 21 for anxiety. A score of 11 or higher indicates the probable presence
of the mood disorder with a score of 8 to 10 being just suggestive of the presence of the
respective state. The two subscales, anxiety and depression, have been found to be
independent measures. In its current form the HADS is now divided into four ranges: normal
(0-7), mild (8-10), moderate (11-15) and severe (16-21).
The Clinical Outcome in Routine Evaluatoin (CORE) is is a client self-report questionnaire
designed to be administered before and after therapy. The client is asked to respond to 34
questions about how they have been feeling over the last week, using a 5-point scale ranging
from 'not at all' to 'most or all of the time'. The 34 items of the measure cover four
dimensions: Subjective well-being, Problems/symptoms, Life functioning and Risk/harm. The
responses are designed to be averaged by the practitioner to produce a mean score to
indicate the level of current psychological global distress (from 'healthy' to 'severe').
The questionnaire is repeated after the last session of treatment; comparison of the pre-and
post-therapy scores offers a measure of 'outcome' (i.e. whether or not the client's level of
distress has changed, and by how much) (Evans, 2000).
The World Health Organization Disability Assessment Schedule 2.0 (WHODAS) (Ustün et al.,
2010) will be used to measure functioning. This scale assesses disability due to physical
and psychological problems, and has been used extensively in research settings.
Procedure Patients who fulfill the inclusion criteria will be provided with information
about the study. Those who consent in writing will be randomly allocated to one arm of the
trial. All participants will complete the demographics questionnaire, HADS, WHO DAS & CORE
during an interview with a primary investigator. Participants in the treatment arm will
attend 1 session of the intervention in addition to the Treatment As Usual. Participants in
the control group will receive treatment as usual during this time. Participants in both
groups will be assessed at the end of 3 months wand then 6 months post intervention.
Data entry and analysis Statistical analyses will be carried out using an Intention To
Treat, using SPSS v22. Both parametric and non-parametric tests will be carried out as
appropriate to compare groups. Treatment and control groups will be compared at the
baseline, using Chi square and t test. A linear regression will be used to compare the two
groups at the end of assessment period. This will be done, using group as the independent,
and the end of assessment scores as dependent variables. Baseline scores and variables that
are not equally distributed in two groups will be used as covariates. All the analyses will
be carried out by FN.
Results and Research Implications If effective, this innovative intervention will reduce
distress, psychopathology and disability in this group and will possibly improve
functioning. Success with this preliminary study could lead to subsequent research to
further investigate this novel intervention.
