Impact of Recovery-Focused CBT on Recent-Onset Bipolar Disorder, Mortality Gap for Schizophrenia and Bipolar Disorder, Correlation of Rheumatoid Arthritis with Bipolar Disorder

This article analysis discusses the impact of recovery-focused cognitive-behavioural therapy (CBT) on patients who have been diagnosed with recent-onset bipolar disorder, a cohort study for determining the mortality gap for individuals suffering from schizophrenia and bipolar disorder from 2000-2014, and a case-control study to determine the correlation of rheumatoid arthritis with bipolar disorder. It also includes information on the population of interest, sample, sampling method, descriptive and inferential statistics used in the articles.

A nationally
representative cohort that
was selected using
primary care electronic
health records that ranged
from 2000 to 2014, and
comprised of comparing

than 16 years, who had
been diagnosed with
bipolar disorder or
schizophrenia. Those
patients who had been

depression and
schizoaffective disorders

Case patients were
generally defined as
being affected with RA
with the presence of at
least 1 recognized RA
diagnosis in medical
records. The diagnosis
comprised of both
seronegative and
seropositive RA patients.
In contrast, the control
group comprised of
randomly selected
patients from the list that
contained CHS enrollees,
exclusive of patients with
RA. Five control patients
had been nominated
against each case patient,
followed by frequency-
matched to the cases, in
relation to age and
gender. Data obtainable
from the CHS database
encompassed gender, age,
smoking status,
socioeconomic status
(SES), and chronic
disease diagnoses.

out-patient clinics, health
teams, primary care teams,
general practice surgeries,

focused CBT had been
attended by the research
participants.
Median age of the general

the adjusted HRs for
bipolar disorder also
demonstrated an increase

the correlation between
bipolar disorder and RA
was no longer substantial
in either females or
males. When stratified
based on the
socioeconomic status,
there was lack of any
significant correlation for

helped to determine the
possible contribution of
