Research Questions
• Does participation in learning in later life
have beneficial effects on wellbeing?
• Are some types of learning more beneficial
than others?
2
Potential Outcomes of Learning
[the three capitals framework, from Schuller, 2004]
• Human capital
» Knowledge and skills
• Social capital
» Social and civic participation, friends, networks
• Identity capital
» Self-esteem, locus of control, sense of purpose, critical
thinking

English Longitudinal Study of Ageing:
Overview
• Original sample taken from 3 sweeps of Health Survey of England (1998,
1999, 2001)
• ELSA is representative of the English 50+ population in private households
at the baseline (2002/03)
• ELSA Wave 1: 2002/03; ELSA Wave 2, 2004/05; ELSA Wave 3, 2007
• Sample size at Wave 1: approx 11,000
• Data available from UK Data Archive
4
Information on learning in ELSA
• Current participation in music, arts or evening
classes
• Current participation in gym/exercise classes
• Recent or current participation in formal education
or training course

Subjective Well-being Measures in
ELSA
• Quality of Life: CASP-19. CASP means control,
autonomy, self-realisation, pleasure
• GHQ-12. General Health Questionnaire
• Life Satisfaction. SWLS – Satisfaction With Life
Scale (Diener)
8
CASP-19 is a theory based Quality of Life Measure
developed under the UK’s
Economic and Social Research Council’s
Growing Older Programme (2000-2003)
See “Quality of Life and the third age: key predictors of CASP19”. Wiggins, Higgs, Hyde and Blane. (2004). Special Issue of
Ageing and Society. Vol 24(3), pp.1-16.

Examples of some of the CASP-19 items
CONTROL & AUTONOMY
 My age prevents me from doing the things I would like to do*
 I feel that what happens to me is out of my control *
 I feel left out of things *
 I can do the things I want to do
 I feel that I can please myself what I do
 Shortage of money stops me doing things I want to do *
* reverse code

Examples of some of the CASP-19 items
SELF- REALISATION
 I feel full of energy these days
 I feel that life is full of opportunities
 I feel that the future looks good for me
13
Examples of some of the CASP-19 items
PLEASURE
 I look forward to each day
 I feel that my life has meaning
 I enjoy the things that I do

Satisfaction with Life Scale

•
“In most ways my life is close to my ideal”
“The conditions of my life are excellent”
“I am satisfied with my life”
“So far I have got the important things I want in
life”
• “If I could live my life again, I would change
almost nothing”
Each coded on 7-point scale, from strongly agree to strongly disagree, and then
summed to obtain score (minimum 0, maximum 30)

Method (1): estimation strategy
• Interest: statistical associations between measures of wellbeing
(response) and measures of learning (explanatory)
• Method issue 1: other observable factors influencing wellbeing
» Control for these observable factors in multiple regression model
• Method issue 2: unobservable (but fixed) characteristics influencing both
wellbeing and participation in learning
» Use change in wellbeing, rather than level of wellbeing as
response variable
•
19
Method (2): dealing with
dropout and non-response
Longitudinal survey: people tend to drop out over time (attrition)
» Use probability weights to allow for dropout from the survey
(standard set of weights supplied with ELSA survey)
Respondents don’t answer all questions: a problem for multiple regression
» Use multiple imputation to overcome this.
(specifically imputation by chained equations in Stata)
20
Multiple regression models for
change in outcome
control variables entered in stages
1. level of outcome variable
2. Age, gender, highest qualification
3. Marital status, work status, income, health status, in
pain, mobility, support from family/friends
4. Change in partner status, work status, physical
health and mobility variables

Magnitude of ‘effects’ of
adult learning?
Quality of Life: mean decline in CASP-19 score between 2 waves approx
0.5; compares to an increase of approx 0.7 associated with
participation in adult learning (music/arts/evening classes)
Life satisfaction: score typically declines by 1 point between 2 waves;
compares to an increase of approx 0.7 associated with participation
in adult learning (music/arts/evening classes)
23
Analysis of sub-groups
 Analysis of impact of music/arts/evening classes on wellbeing
showed few differences by sub-group (gender, age group, work
status, marital status)
 Evidence that those with higher education who participated in
learning had larger gains in wellbeing than people with no
qualifications who participated in learning
24
Summary of main results

Evidence that participation in learning linked to increased wellbeing

Participation in music/arts/evening classes remains significantly
associated with wellbeing, even after allowing for many other factors

Other forms of learning, including formal education and training
courses, not associated with increased wellbeing (after allowing for
other factors)
25
What are the implications of these findings?
•
Learning in later life can have an impact on individual wellbeing
 A contribution to ‘successful ageing’
•
Only some types of learning have direct impact on wellbeing
 Participation in non-vocational learning i.e. leisure classes
 No evidence that formal education/training courses have an effect
•
26
Key message for policy
 While vocational training is important in many respects other forms of
learning, including learning for pleasure/interest, should not be
neglected
Implications (continued)
•
The research does not rule out vocational training having an indirect
impact on wellbeing
•
For example, older people who regard themselves as unemployed
have much lower wellbeing (on average) than those who are in
employment
•
So IF vocational training helps to keep older adults in employment
then it would contribute to wellbeing in an indirect way
