Aim
Demonstrate how nurses, doctors, and health
professionals, who have little or no direct
access to statistician, can use SPSS confidently
to convert their data into information for the
advancement of research in health and medicine.

Effective Design is guided by

• A Clear Research Question
• Selecting an appropriate Study Design
• Selecting the appropriate Statistics

4
Using a Case Study

• The Aim To examine the effect of legs ulcers on
  anxiety and depression in relation to quality of
  everyday life.
• Design choices Case Control study was selected
  to compare result result with National
  Statistics.
• Perform analyses Systematic selection of
  statistics to use

5
About the Data

• 190 leg ulcer patients (males 101 and
  females89) were recruited by consent, in the
  Northwest - Lancashire, Merseyside and Greater
  Manchester.
•  
• Methodology Mixed Methods approach was used.
  Qualitative and Quantitative data were collected
  via questionnaire and interviews.
• This presentation focuses on the quantitative
  data analysis.

6
Age by gender

• Mean Age by gender was examined for any
  significant differences between male and female.
•  
• Independent T-test was used to compare the mean
  age by gender in leg ulcer patients. Females
  (mean age 70.17, SD13.69) were significantly
  higher t(188)12.57 plt0.01 than males( mean
  age64.77, SD15.03).
•  
• Office for National Statistics1(ONS) reports
  from the General Practice Research Database
  (GPRD) that there are fewer adult men (44 per
  1000) receiving drugs for anxiety and depression
  than women (101 per 1000) between 1994-96. Same
  study reveals mean age differences of men (36.2)
  and women (81.9) receiving treatment for
  depression and anxiety. Note this is general
  not leg ulcers.

Mobility and Anxiety

• Independent sample t-test was used to examine
  the different levels of anxiety between those who
  are mobile and those who are not.
• No significant difference in the levels of
  anxiety t(188)-1.246 pgt0.05) were found
  between the fully mobile (mean score 6.05,
  SD4.197) and the limited/immobile (mean score
  6.98, SD4.653) groups.

8
Mobility and Depression

• Independent sample t-test was used to examine
  the different levels of anxiety between those who
  are mobile and those who are not.
• No significant difference in the levels of
  anxiety t(188)-2.905 plt0.05) were found
  between the fully mobile (mean score 4.93,
  SD3.505) and the limited/immobile (mean score
  6.75, SD4.064) groups.

9
Depression scores by gender

• Depression scores by gender were examined for any
  significant differences between male and female.
• Independent T-test was used to compare the mean
  anxiety scores by gender in leg ulcer patients.
  No significant difference t(188)-0.102 pgt0.05
  was found between Females(mean depression score
  5.38, SD3.67) and males(mean depression score
  5.33, SD3.76).

Conclusion
1. I have use the case to go through the logical
line of thinking 2. Highlighted the importance
of aligning Research Question gt Study Design
gt Inform the choice of Stats gt for effective
study outcome 3. I have demonstrated using the
case study, how the use of SPSS helped to convert
the data into information to advance research in
health and medicine.
