HEALTHY IRELAND
A Conceptual Approach towards a Research and Data Plan
Presentation at Department of Health, 12th February 2014
KEY CONCEPTS IN HEALTHY IRELAND
Current adverse health trends in Ireland are similar to those causing concern in other developed countries. They include projected significant increases in levels of
chronic disease,
exposure to health risks,
growing health inequalities, and
difficulty in accessing care when it is needed.
Healthy Ireland, page 6
KEY CONCEPTS IN HEALTHY IRELAND cont. …
Healthy Ireland is designed to bring about real, measurable change and is based on an understanding of the determinants of health. Health and well-being are affected by all aspects of a person’s life;
economic status, education, housing, the physical environment in which people live and work.
Health and well-being are also affected by policy decisions taken by Government, the individual choices people make about how they live, and the participation of people in their communities.
Healthy Ireland, page 6
KEY CONCEPTS IN HEALTHY IRELAND cont. …
This means addressing risk factors and promoting protective factors at every stage of life
from pre-natal, through early childhood, adolescence, adulthood and into old age, to support lifelong health and well-being.
Healthy Ireland, page 6
HIGHLIGHTED RISK FACTORS AFFECTING POSITIVE HEALTH OUTCOMES
The major risk factors identified in Healthy Ireland are:
Overweight and Obesity
Mental Health
Smoking
Alcohol and Drugs
But note the conceptual confusion in the above: smoking, alcohol and drugs are pure behaviours and thus potential risk factors. Obesity is a health outcome, but could still be seen as a proxy for behaviour in a similar way. By contrast, mental health is first and foremost a health outcome!
Healthy Ireland, page 10
IN SUMMARY
Healthy Ireland provides an integrated approach to looking at higher level Health and Well-being outcomes,
HI attempts to identify the key Risk and Protective Factors that affect these outcomes,
HI attempts to understand the differentials in health outcomes for different groups within Irish society (i.e. the Social Gradient) and
HI aims at mapping out the movement of key indicators over time, both in terms of health and well-being outcomes and the key factors which affect these.
A CONCEPTUAL APPROACH TO DEVELOPING A RESEARCH AND DATA PLAN
When formulating a conceptual approach to a Research and Data Plan aimed at supporting evidence-based policy making, it is our contention that this can best be achieved on the basis of understanding the structural relationships between key health outcomes and their principal determinants.
This can best be achieved by analysing major Irish datasets (GUI, TILDA, SLAN) using appropriate statistical techniques.
Key latent concepts can be operationalised as composite indices, to facilitate ongoing monitoring of risk and protection factors and health outcomes.
Data collection should be based on a need-to-know approach and guided by the a priori identification of key concepts.
OVERVIEW OVER REST OF PRESENTATION
The remainder of this presentation is organised in four sections:
1.The first section will demonstrate the usefulness of a Structural Equation Model in understanding Child Well-being using the Growing UP in Ireland data.
2.This is followed by a demonstration of the determinants of Health and Well-being of older people using TILDA.
3.The third Section discusses the underlying principles informing Composite Index Construction.
4.The final Section outlines how the approach(es) may be applied in the context of Healthy Ireland, and particularly the development of a Research and Data Plan.
UNDERSTANDING CHILD WELL-BEINGA STUDY BASED ON THE 9-YEAR COHORT OF GUI
The central question guiding our research is:
What influences the well-being of children and their families?
Drawing on Ryff and Keyes (1995), we define well-being as a multi-dimensional construct
situated between the individual and the social whole, comprising:
Emotional well-being (absence of depression, internalising behaviours)
Subjective well-being (e.g. life satisfaction)
Relational well-being (including family and intimate relationships)
Positive self-concept (self-esteem, self-efficacy)
Positive work and/or study role
Absence of symptoms or externalising behaviours
OUR APPROACH
We situate the well-being of children within the context of the “family system”.
We develop an integrated theoretical model of well-being and the family system, based on previous research.
We seek robust latent multi-item measures of key concepts in this model.
We distinguish between
the measurement model (items and scales used to measure key concepts),
the structural model (relationships between the key concepts), and
the risk and protective factors that constitute the context of child development.
We use Structural Equation Modelling techniques to estimate parameters in our model.

KEY FINDINGS
1. The analysis confirms the importance of the mother’s well-being as a mediating factor on the child. A one unit improvement in the mother’s well-being is associated with a 0.4 unit direct improvement in child well-being.
2. In stark contrast, the direct effect of the father’s well-being on the child (.04) is almost negligible once we control for other factors.
3. A striking result is the strongly mediated effect of many contextual influences, in harmony with the ecological model of child well-being.
4. With the exception of the mother’s health and the Haase-Pratschke Deprivation Index, which have a significant direct effect on child well-being, all other socio-economic factors, including financial variables and local area problems, have a distal effect on child well-being that is mediated by the mother’s well-being.
DISCUSSION
1. The conceptualisation of well-being as a higher-order latent concept reveals itself to be a powerful and well-supported hypothesis.
2. The assumption that the well-being of children cannot be understood without simultaneously analysing the well-being of their parents is reinforced.
3. All of the key influences identified in this analysis are in line with our previous research on child and family well-being using independent data – including the finding that a unit change in maternal well-being is associated with almost half a unit change in child well-being.
4. Parents act as a buffer between economic risk factors and child well-being.
5. Socio-economic risks do influence parental well-being, and thus have a mediated effect on children.
6. The model presented here reflects the situation of two-parent families only. As we elected to study the dyadic relationships between caregivers and between caregivers and children, single parents were excluded. The next step would therefore be to focus on the primary caregiver and child, thus including single parent families.

REFLECTING ON THE DESIGN OF THE GUI DATASET
The GUI 9 year-old cohort data has a number of strengths…
a large sample, panel design, multiple outcome measures, independent assessments, and a clustered sampling design consistent with an “ecological” approach.
…but, given the overwhelming influence of parental well-being on child well-being, the data has also some weaknesses:
It does not provide sufficient information on relationships (reciprocity, support, intimacy, conflict) within the neighbourhood, family or friendship group.
It lacks a range of important measures, such as conflict between intimate partners, subjective well-being, physical symptoms, positive/negative affect, adult self-concept.
In developing a Research and Data Plan for Healthy Ireland it is important that the key structural components that determine overall health and well-being are well understood before signing off on what data should be collected for the future.
LEARNING FROM TILDA
There are four questions which guide our analysis of the TILDA data:
What is the relationship between Overall Health and Overall Well-being?
What is the influence of mediating factors such as an Active Lifestyle and the level of
Health Care utilised?
How are these concepts influenced by a wide range of contextual factors?
How do we develop an understanding of Ageing, other than being simply synonymous
with age?
Note the similarity of questions raised in developing a Research and Data Plan for
Healthy Ireland!
KEY CONCEPTS TO BE CONSIDERED
Well-being
Again, we define well-being as a multi-dimensional construct situated between the
individual and the social whole, comprising:
Emotional well-being (absence of depression)
Loneliness
Subjective well-being (e.g. life satisfaction)
Positive self-concept (self-esteem, self-efficacy)
KEY CONCEPTS TO BE CONSIDERED
Overall Health
Rather than looking at the effect of contextual factors on each specific dimension of
Health, we construct a measure of Overall Health Status as a higher-level latent concept
comprising five components:
Blood Measures
Movement Measures
Neuropsychological Measures
Eyesight, and
Sensory Functioning
THE DATASET
Our analysis is based on the first wave of TILDA data, which has many strengths…
Large sample, panel design, multiple measures, independent assessments, clustered sampling design, “ecological” approach.
Unlike the GUI dataset, TILDA also provides information on self-concept , subjective well-being, physical symptoms, reciprocity and support within the neighbourhood, family or friendship group.
…but the TILDA data still has some weaknesses:
It notably lacks a measure of personality traits (positive/negative affect), which has been shown to be of importance and conceptually and empirically different from depression.
Nevertheless, almost all of the constituents to well-being thought to be of importance can be implemented within the TILDA analysis.

AN IMPORTANT NOTE ON MISSING DATA
The dataset used to estimate the TILDA Well-being Model comprises of all subjects where there exists a complete set of data for all constructs included. It is divided into two samples, a male sample with 1,828 cases, and a female sample with 1,833 cases.
Missing data resulted in the following loss of records:
Failure to return the essential self-completion questionnaire leads to a loss of roughly 15% of the sample, or about 1,300 cases.
Failure to participate in the health assessment leads to a further reduction of almost 2,000 cases.
Failure to provide data on incomes and assets imposes the loss of a further 1,300 cases approximately.
The need to exclude young partners from the sample leads to a further loss of roughly 20 men and 150 women.
Although the complete TILDA sample contains 8,504 cases, the cumulative impact of missing data implies a severe amount of data lost.

The final Model is estimated separately for the male and female samples and comprises:
36 variables per sample
A total of 1,332 observed variances and covariances
Requiring the estimation of 363 parameters (107 regression coefficients for each sample, 16 constrained to be equal across samples
41 variances for each sample, 21 constrained to be equal across samples
52 covariances for each sample
Overall more than 10 cases per parameter estimated.
Despite the significant amount of data lost, this represents a very powerful and well-supported model.

KEY FINDINGS
1. The analysis confirms the pivotal importance of age for the health and well-being of older persons. A one unit (STD) increase in a person’s age is associated with a 0.75 unit deterioration in the person’s overall health.
2. This, however, does not automatically translate into a similar deterioration of personal well-being. Whilst a person’s health is a strong influence on his/her well-being, the relationship (.24) is not as strong as one might expect and indeed, the moderate negative influence of age via the deterioration in health is partially offset by the positive direct effect of age on well-being (.23) .
3. The other major factor which decouples a person’s well-being from his/her overall health alone, is the strong positive effect (.42) associated with a high quality relationship. It should, however, be noted that one could equally postulate a model in which the quality of relationship is taken as a measurement of a person’s well-being.
KEY FINDINGS
4. As is well-supported by other research, social class has a strong effect (.32) on the health of an older person, but surprisingly, no statistically significant direct effect on personal well-being.
5. Instead, the effect of social class on well-being is entirely mediated; firstly via the already established path from health to well-being and secondly, by the complex way in which it affects a person’s active lifestyle.
6. There exists a strong (.28) direct effect of social class on living an active life style. Poorer health has a strong negative effect (-.72) and an active life style has a positive effect (.14) on a person’s well-being.
OTHER IMPORTANT FINDINGS
1. Medical Screening is positively associated with High Social Class (.18), but negatively associated with Age (-.26) and being Unemployed (-.09).
2. The amount of Care Received from relatives reflects the degree of Impairments (.17), Close Relatives/Friends (.07) and Car Access Problems (.08). Lesser Care Received is associated with better Overall Health (-.08).
3. Living Alone has a negative effect on Health and Personal Well-being, as well as an indirect negative effect on well-being via Alcohol Problems.
4. A good Relationship Quality and having Close Friends and Relatives have positive effects on Active Lifestyle, Overall Health and Personal Well-being.
5. Experiencing Transport Problems negatively affects both Overall Health and Personal Well-being.
6. Religiosity does improve a person’s Well-being, both directly and indirectly via improved drinking and smoking behaviour.
7. In contrast, being unemployed has a negative effect on well-being.
IMPLICATIONS FOR THE DEVELOPMENT OF THE RESEARCH AND DATA PLAN
Our analysis of TILDA provides strong support for a conceptual approach which builds on the use of latent variables in the context of a structural equation modelling environment.
The approach is able to distinguish between the health and well-being of a person, as well as quantifying the influence that key concepts such as social class and lifestyle have on these outcomes.
Of the four underlying tenets of Healthy Ireland, Mental Health, Smoking and Alcohol and Drugs are already successfully identified with their respective effects on Health and well-being.
It may be possible to specify the model in such way as to align it further with the assumptions underlying Healthy Ireland.
FROM LATENT VARIABLE TO COMPOSITE INDICATOR CONSTRUCTION
The conceptualisation of key aspects of health and well-being and their determinants as latent concepts is in line with the rising interest internationally in the construction of Composite Indicators.
It facilitates an understanding of the key dimensions of these concepts a definition as to how these can be measured the ability to model their structural relationships the identification and measurement of key influences on the latent concepts The monitoring of changes in both outcomes and key determinants over time.
Composite Indicators are tools for policy-making
Rapid development of economic indicators after WWII, but slow catch-up in “social” arena.
Indicators are a proxy for unobservable phenomena (broad picture)
Practical, intervention-oriented tools for decision-making
Without theories, statistical data merely “describe the symptoms”
The following slides are excerpts from a recent 2-day workshop delivered at the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA).
COMPOSITE INDEX CONSTRUCTION IN CONTEXT
PRINCIPLES IN THE CONSTRUCTION OF COMPOSITE INDICATORS
What is badly defined is likely to be badly measured …
A sound theoretical framework is the starting point in constructing composite indicators. The framework should clearly define the phenomenon to be measured and its sub-components and select individual indicators and weights that reflect their relative importance and the dimensions of the overall composite. Ideally, this process would be based on what is desirable to measure and not which indicators are available.
PRINCIPLES IN THE CONSTRUCTIONOF COMPOSITE INDICATORS
Evaluation Criteria for Selection of Variables: Relevance: are the data what the user expects? Accuracy: are the figures reliable? Comparability: are the data in all necessary respects comparable
across countries (units of analysis)? Completeness: are domains for which statistics are available
reflecting the needs expressed by users? Coherence: are the data coherent with other data? Timeliness and punctuality: does the user receive the data in time
and according to pre-established dates? Accessibility and clarity: is the figure accessible and
understandable?
PRINCIPLES IN THE CONSTRUCTIONOF COMPOSITE INDICATORS
Preliminary Data-Analysis in Variable Selection:
Uni-dimensional Construct; i.e. construct covering a single dimension
Undertake Reliability Analysis Cronbach’s Alpha, which measures internal consistency of a set of items
Cronbach’s alpha (α) Internal Consistency
greater than 0.9 excellent
0.8 – 0.9 good
0.7 – 0.8 acceptable
0.6 – 0.7 questionable
0.5 – 0.6 poor
less than 0.5 unacceptable
PRINCIPLES IN THE CONSTRUCTIONOF COMPOSITE INDICATORS
Preliminary Data-Analysis in Variable Selection:
Multi-dimensional Construct; i.e. construct covering multiple dimensions
Undertake Factor Analysis to identify sufficiently supported dimensions
(subject to sufficient n)
Ask whether the dimensions have substantive meaning
Avoid constructs which are “indicator rich but information poor”
Undertake Reliability Analysis (Cronbach’s Alpha) to assess internal
consistency of each dimension.
FROM OBJECTIVES TO DESIGN
Dimensionality
Composite indicators seek to measure multi-dimensional concepts which cannot be captured by single indicators
Other terms: domain, facet, sub-component, factor, pillar
Relates to the pattern of correlations between variables
Multi-level, hierarchical phenomenon
Has consequences for weighting and aggregation
Analysis may be theory-driven or data-driven
No empirical answers to questions about dimensionality
FROM OBJECTIVES TO DESIGN
Timeliness and Temporal Dynamics
Timeliness refers to the period that elapses between the availability of
an indicator and the phenomenon described
Temporal dynamics are important for benchmarking, programme
assessment and causal analysis
Uses of composite indicators should be anticipated to ensure that
design allows for required temporal dynamics:
“For time-dependent studies, in order to assess country performance across years, the average across countries … and the standard deviation across countries … are calculated for a reference year, usually the initial time point...” (Nardo et al., 2005, pp. 60-1).
FROM OBJECTIVES TO DESIGN
Sensitivity Analysis (OECD Indicator Handbook)
1. inclusion and exclusion of sub-indicators.
2. modelling data error based on the available information on variance estimation.
3. using alternative editing schemes, e.g. single or multiple imputation.
4. using alternative data normalisation schemes, such as re-scaling, standardisation, use of rankings.
5. using different weighting schemes, e.g., methods from the participatory family (budget allocation, analytic hierarchy process) and endogenous weighting (benefit of the doubt).
6. using different aggregation systems, e.g., linear, geometric mean of un-scaled variable, and multi-criteria ordering.
7. using different plausible values for the weights.
EXAMPLES OF COMPOSITE INDICATORS
Examples of Composite Indicators:
UN Human Development Index (HDI)
OECD Technology Achievement Index (TDI)
UK Index of Multiple Deprivation (IMD)
Pobal HP Deprivation Index in Ireland (HP Index)
KEY LESSONS FROM THE HISTORY OF INDICATOR CONSTRUCTION (COBB & RIXFORD, 1998)
1. Having a number does not necessarily mean that you have a good indicator.
2. Effective indicators require a clear conceptual basis.
3. There's no such thing as a value-free indicator.
4. Comprehensiveness may be the enemy of effectiveness.
5. The symbolic value of an indicator may outweigh its value as a literal measure.
6. Don't conflate indicators with reality.
7. A democratic indicators program requires more than good public participation processes.
KEY LESSONS FROM THE HISTORY OF INDICATOR CONSTRUCTION (COBB & RIXFORD, 1998) CONT.
8. Measurement does not necessarily induce appropriate action.
9. Better information may lead to better decisions and improved outcomes, but not as easily as it might seem.
10. Challenging prevailing wisdom about what causes a problem is often the first step to fixing it.
11. To take action, look for indicators that reveal causes, not symptoms
12. You are more likely to move from indicators to outcomes if you have control over resources.
HEALTHY IRELAND: MONITORING AND EVALUATION
Healthy Ireland states that it will be subject to rigorous monitoring and evaluation.
An Outcomes Framework will be developed that will specify key indicators to underpin each of the four high-level goals.
Targets for quantifiable improvements will be set, where appropriate.
Regular measurement of these indicators will allow progress to be assessed over time.
HEALTHY IRELAND’S GOALS
Healthy Ireland states four central goals:
Increase the proportion of people who are healthy at all stages of life
Reduce health inequalities
Protect the public from threats to health and wellbeing
Create an environment where every individual and sector of society can play their part in achieving a healthy Ireland
PATHWAY TOWARDS A RESEARCH AND DATA PLAN FOR HEALTHY IRELAND
1. Identify and agree on key concepts (not individual data!) to be measured. Delphi method may be appropriate for this step.
2. Identify possible data sources from which key concepts can by approximated.
3. Test the coherence of these measurement models using Reliability and Confirmatory Factor Analysis.
4. Determine the structural relationships between key concepts using Structural Equation Modelling.
5. Develop a plan how these measurements can be repeated over time to assist monitoring and evaluation.
