2What is the Childrens Fund?
Essentially it is a pot of money (initially 450m
in total) disbursed disproportionately to each
Local Authority in England. Each Local Authority
has generated Partnerships that, in turn, have
developed services aimed at children and young
people between 5 and 13. These services are
intended to be preventative and based on
partnership working and the participation of the
young people and their families.
3What are the aims of the Childrens Fund?
To help overcome poverty and disadvantage More
specifically, to 1. Reduce truancy 2. Increase
educational attainment. 3. Reduce crime and
anti-social behaviour. 4. Improve health.
4How is the National Evaluation of the Childrens
Fund organised?
- It is a joint project between the University of
- Birmingham and the Institute of Education in
London, - directed by Professor Anne Edwards in Birmingham.
It - started in January 2003 and, as things stand, is
due - to end in March 2006.
- There are two main research strands
- (i) Strand A in London, using a quantitative
approach to measuring implementation and
estimating impact.
5How is the National Evaluation of the Childrens
Fund organised?
- (ii) Strand B in Birmingham, using a mostly
qualitative and case study approach to learning - and understanding more about the operation of
the Childrens Fund at a local level in terms of
the Partnerships activities in relation to
multi-agency working, participation and their
views about prevention. - In addition, each Partnership has a small budget
- either to commission or to carry out themselves
local - evaluations.
6Strand As research questions
- Can any improvements in the outcomes introduced
- earlier be attributed to the operation of the
Childrens - Fund? In other words, has the Children Fund had
an - impact?
- However, answers to question 1 can only be
- understood in terms of answers to a prior
question - How many, and what kinds of children and
families, - have actually used the services provided under
the - Childrens Fund umbrella? In other words, how
- successful has the implementation of the
Childrens - Fund been?
7Strand As main methodological problems
- 1. Self-selection.
- 2. Heterogeneity of services.
- 3. Secondary analysis of datasets collected for
other purposes.
8Basic evaluation model
9Millennium Cohort Study (MCS)
MCS First Survey Fieldwork
- Birth dates
- England Sept 2000 to Aug 2001
- Fieldwork child 9-10 months old
- England Jun 2001 to Aug 2002
10Millennium Cohort Study (MCS)
MCS2
- The second MCS survey took place around the time
of the childrens third birthdays - The survey follows all those 11,533 families who
took part in MCS1 in England plus some 500 New
families who were missed by DWP last time - Fieldwork started in September 2003 in England
and will finish early in 2005.
11MCS Target Sample, Sweep 1
All children living in the selected wards
Observed mean cluster size across the UK is 47
but the range is from 7 to 403.
12Millennium Cohort Study (MCS)
MCS2 and the Childrens Fund
- 76 English wards used in the second sweep of the
MCS were also wards with Childrens Fund services - In these wards families with children aged
between 4 and 15, in addition to their 3 year old
cohort child, were asked information about (up to
2) older siblings as part of the NECF.
13Millennium Cohort Study (MCS)
Older Siblings (4 - 15 Year olds)
- Use of services
- Involvement with services
- Mother report on Strengths and Difficulties
- Mother report on spare time activities for
children aged 4-9 years - Siblings aged 10-15 do self-completion on own
activities including truancy, smoking, substance
use, etc - Information collected about the schools attended
14Millennium Cohort Study (MCS)
Possible Analysis
- Data collected at one point in time so although
the MCS itself is longitudinal, the data on older
siblings are cross sectional. - We can report descriptive statistics on what type
of people use Childrens Fund services and
compare them to those who do not very helpful
to policy makers who are interested in issues of
targeting.
15MCS3
- The third sweep of MCS will take place around the
- time of the childrens fifth birthdays, after
they - have started compulsory schooling.
- Fieldwork will start in November 2005 and is due
to - end in May 2006 in England and Wales.
- The original intention had been to measure the
- older sibs again in MCS3 but, at this point,
funding - for this is still uncertain.
16PLASC / NPD
- Pupil Level Annual Schools Census and National
Pupil Database - Annual survey from 2002
- The purpose of this administrative dataset is to
provide a census of pupils in England and Wales
17PLASC / NPD
- Free School Meals
- SEN
- Ethnicity
- English as a second language
18PLASC / NPD
- PLASC/NPD is rich in detailed information on
educational outcomes such as KS scores and
examination results. - Results at KS1, KS2, KS3 and KS4
- Exclusion from school
19PLASC / NPD
- Schools with school-based programmes will be
matched with similar schools without such
programmes and the relative progress of pupils
with the same characteristics in the two groups
of schools will be compared. -
- The 2003 data is longitudinal, containing prior
Key Stage attainment. KS1 will be used as a
control we do not have data on foundation stage
profiles.
20Families and Children Survey (FACS)
- FACS is a refreshed panel survey, which started
in 1999. FACS started life as the Survey of Low
Income Families (SOLIF). Therefore for the first
two waves it considered only low-income families.
- We will be using FACS from 2002 onwards.
- 2003 fieldwork was carried out September 2003 to
January 2004 this will provide us with an
outcome measure.
21Families and Children Survey (FACS)
- Library
- Parent and toddler group
- Playgroup
- Nursery
- Leisure Centre/Pool
- Park/playground
- GP
- Community Health Services
- Satisfaction as well as use
22Families and Children Survey (FACS)
- Outcomes Education, Delinquency and Health
(2002 and 2003)
- Absence from school
- Behavioural problems and exclusion
- Homework completion
- Smoking, drinking, drugs
- Trouble with the police
- Qualifications (GCSE etc)
- Parents subjective view of how child is doing
- Health
23Families and Children Survey (FACS)
- We will use FACS to compare outcomes in
Childrens Fund wards and non Childrens Fund
wards. We will analyse the links between living
in a Childrens Fund area, take up of services,
and relevant outcomes. - The advantage of FACS is that we have individual
child level measures for both 2002 and 2003. The
disadvantage is that exposure to services by 2003
will not have been great.
24Heterogeneity
Plewis, I. and Mason, P. (2005) What works and
why combining quantitative and qualitative
approaches in large-scale evaluations. Internation
al Journal of Social Research Methods
(forthcoming). Plewis, I. (2002) Modelling
impact heterogeneity. JRSS(A), 165, 31-38.
25Heterogeneity
Suppose our outcome of interest, a measure of a
young persons criminal behaviour, can be assumed
to be measured on an interval scale, and suppose
that the sample members are clustered into areas,
some of which are intervention areas and some are
controls. We label the outcome yij where j (j
1..J) is the subscript for area and i (i 1..nj)
is the subscript for the young person. We label
the variable defining the intervention as xj
with, for now, x 1 for the intervention areas
and 0 for the control areas.
26Heterogeneity
We want to introduce heterogeneity into our model
and we can partition this heterogeneity into four
classes heterogeneity that is a characteristic
of (1) individuals and (2) the areas in which
they live, and heterogeneity that is created by
(3) the intervention at the individual level and
(4) at the area level. We can represent these
four classes by variables z, using the
superscript (x) for variables pertaining to the
intervention
27Heterogeneity
(1) zij are essentially fixed characteristics of
the target individuals - age, sex, social class
and so on, including a pre-intervention measure
of the outcome. The question here is does the
intervention effect vary according to these
fixed characteristics at the individual level
(level one)? (2) zj are fixed characteristics
of the area (and, therefore, constant for
individuals within areas) - urban or rural area,
proportion unemployed and so on. Now the
question is is the intervention effect
different for different types of areas?
28Heterogeneity
(3) zij(x) are characteristics of the
intervention as experienced and perceived by the
individual, notably whether a target family
actually uses the service. (4) zj(x) are
characteristics of the intervention as it is
delivered at the area level organisations and
their characteristics delivering the
intervention and partnership arrangements behind
them, level of user participation in service
design and delivery, forms of delivery such as
how established the service is, and so on. These
are key variables for answering the what works
question measures of many of them are derived
from qualitative investigations.
29Heterogeneity
(1a)
(1b)
(1c)
(1d)
with the intervention variable (i.e. xj) at level
two (areas).
30Heterogeneity
The important parameters are ?01 in (1b) this
shows, in essence, whether the intervention
affects mean outcome at the area level, having
controlled for all the z variables. In other
words, a negative value of ?01 shows that
criminal behaviour was, on average, lower in the
intervention areas. The parameters ?03, ?04, ?11
and ?21 tell us about variability around this
mean (which might be zero). Thus ?03 a
non-zero value indicates that the intervention
varies in its effect according to the fixed
characteristics of the area. For example, the
intervention might be more effective in rural
areas.
31Heterogeneity
?04 a non-zero value indicates that the
intervention varies in its effect according to
the way the service is delivered at the area
level. For example, an intervention might be more
effective if young people were involved in its
design. ?11 in 1(c) this tells us how much
heterogeneity there is in terms of fixed
individual family characteristics. For example,
an intervention might be more effective for young
people living in single-parent families. ?21 in
1(d) this tells us how much heterogeneity there
is in terms of characteristics of the
intervention as experienced by individuals. For
example, we would expect an intervention that is
used regularly to be more effective than one that
is only used sporadically.
