3. Analytical Focus and Contextualization
In this preliminary study of mental health, see Murtagh and Farid (2017),
the following is described: Choice and selection of main and supplementary
variables. Therefore: our main focus of analysis, and an explanatory context.
In this data source, “Adult Psychiatric Morbidity Survey, England, 2007”,
this reference is important, “HSCIC, Health and Social Care Information Centre
(National Health Service, UK)”, 2009. “National Statistics Adult Psychiatric
Morbidity in England” – 2007, “Results of a household survey, Appendices and
Glossary”. 174 pp. Available at:
http://www.hscic.gov.uk/pubs/psychiatricmorbidity07
There are 1704 variables, including questioning of the subjects about
symptoms and disorders, psychoses and depression characteristics, anti-social
behaviours, eating characteristics and alcohol consumption, drug use, and
sociodemographics, including gender, age, educational level, marital status,
employment status, and region lived in.
An initial display of the neurotic symptoms and common mental disorders
sought to have socio-demographic variables as supplementary. But these
were projected close to the origin, therefore showing very little differentiation
or explanatory relevance for the symptoms and disorders data.
It is found that factor 1 is explained as PTSDcom, “Trauma screening
questionnaire total score” versus all other variables. Factor 2 is explained as
“CISR-FOUR” versus “nosymp”. These are, respectively, “CIS-R score in four
groups, 0-5, 6-11, 12-17, 18 and over. (CIS-R = Common Mental Disorders
questionnaire)”; and having no neurotic symptoms in the past week.
It was sought to characterize the socio-demographic data, and then to see
if the neurotic symptoms and common mental disorders data could be
explanatory and contextual for the socio-demographic data. But no
differentiation was found for these supplementary variables, indicating no
particular explanatory capability in this particular instance. It may be just noted
how the main and supplementary variables were interchanged. Respectively,
the symptoms and demographic variables were main and supplementary; then
the main and supplementary variables were the demographic variables and
symptoms. This was done in order to explore the data. It was seen to have age
and education level counterposed to home region. It was also seen to have
educational level coun-terposed to: employment status, gender, marital
status, ethnicity.
Finally, it was checked whether neurotic symptoms and common mental
disorders data should be jointly analysed with the socio-demographic data.
