Getting There Slowly. . . . . “There is surely a place for research into psychological interventions that improve quality of life for patients after diagnosis or treatment. Maybe happiness (or reduced happiness) has some effect on survival” Letter to British Medical Journal Nov 2002
What is Quality of Life? What does it denote? Something we increasingly referred to What attributes can be used to measure QoL? “The best way of approaching quality of life measurement is to measure the extent to which people's 'happiness requirements' are met - i.e. those requirements which are a necessary (although not sufficient) condition of anyone's happiness - those 'without which no member of the human race can be happy.” McCall 1975
Subjectivity of Quality of Life Recognising subjectivity of QoL is key Measuring the gap between what a person wants and what they have Expectations are adjusted to lie within realm of what is possible People with difficult life circumstances can maintain a QoL
“Meaning” “Quality of Life is tied to perception of 'meaning'. The quest for meaning is central to the human condition, and we are brought in touch with a sense of meaning when we reflect on that which we have created, loved, believed in or left as a legacy.” Frankl, 1963
QoL is NOT . . . . . Being Happy Being disease free Feeling warm and fuzzy MULTIDIMENSIONAL Having money CONCEPT Driving that car Having a good job IT’S ALL OF THE ABOVE AND MORE . . .
QoL may be. . . Ability Adaptation Appreciation Basic Needs Belonging Control Demands Distress Diversity Enhancement Enjoyment Environment Expectations Experiences Flexibility Freedom Fulfilment Gaps Gender Happiness Health Hopes Identity Spirituality Improvement Inclusivity Integrity Isolation Judgements Knowledge Lacks Living Conditions Mismatches Needs Opportunities Perceptions Pleasure Politics Possibilities Religion Safe Satisfaction Security Self-esteem Society Status Stress Truth Well-being Wishes Working Conditions

Health Related Quality of Life (HRQoL) Very Broad Concept The effects of ill-health on Psychological, Social, Physical well-being Multidimensional No overall agreement on: what is included in QoL ? how to measure QoL ? gold standard ? Despite this. . . . . QoL scales still being made Jenney & Campbell 1997
Quality of Life measures Disease / Population Specific Particular health problems over several health domains, e.g. Asthma Quality of Life Questionnaire Dimension Specific Particular aspects e.g. psychological, usually produces a single score Generic Measures Across different patient populations, measures many health domains e.g. SF-36 Individualised Patients include and weight importance of aspects of their own life, producing a single score e.g. Patient Generated Index Utility Specific Economic evaluation, preference for health states, produces a single index e.g. EuroQol
Popularity of QoL measures 800 articles in BMJ since 1992 3921 papers concern QoL (17%) 1275 different scales of QoL 144 in 1990 650 in 1999 increase of 450% Disease / Population specific scales 1819 46% Generic measures scales 865 22% Dimension specific scales 690 18% Utility specific scales 409 15% Individualised scales 62 1% Garratt et al. 2002
How is QoL used in Research? • Descartes – division of body and mind • Biopsychosocial model reunified body & mind • Studies should incorporate the patient's perspective of outcome • Essentialto provide evidence of impact on patient in terms of • Healthstatus • Health-related quality of life
Traditional model of Disease Development Pathogen Disease(pathology) Modifiers Lifestyle Individual susceptibility
Biopsychosocial model of Illness Pathogen Illness (well-being) Psychosocial Factors Attitudes Behaviour Quality of Life
Why use QoL as an Outcome? • Cannot remedy the problem? • Cannot make things any better? • Next best thing = Increase in employee QoL • Central concept in health work • WHO 1948 “Physical, mental and social well-being” • 4 core components: • Disease state and Physical symptoms • Functional status • Psychological functioning • Social functioning

Methodological Problems of QoL • Numerous measuresof QoL in some specialties • Little standardisation • Two prerequisites for standardisation • Primary researchthrough concurrent evaluation of measures • Secondary researchthrough structured reviews of measures • Recommendations from such QoL scales may not be simple to use clinically
Methodological Problems of QoL QoL scales NOT independent of the patient Shopping Bag of experiences? “Shopping Trolley” Psychological status: Overlap between Affective and Somatic states Data dredging Too Specific designated: populations / diseases, timeframes, situations “Spirituality” ignored Generic QoL scales may suffer Developers of scales have vested interests Most popular QoL scales = Pushiest developer
Psych / Perceptual Process of Illness Internal Process “Do I notice internal changes?” “Should I interpret them negatively?” “Should I think they are important?” External processes “Do I notice external sources?” “What should I believe about it?” “What should I do about it?” MENTAL SCHEMA Internal representation of the world (knowledge, attitudes, beliefs) What do we believe about health? What do we believe affects health?
Factors Influencing Symptom Development Selective Internal Attention Tedious & un-stimulating environment Little communication Stressful environment Learned behaviours “Negative Affectivity” OVER FOCUS ON SYMPTOMS Comparisons Attributions Responses Blame Pessimism
Factors Influencing Symptom Development • Selective External Attention • Heightened concern about risk involuntary uncontrolled lack of information dreaded consequences • Mistrust of government / industry • Attitudes about medicine • Political agenda • Legal agenda • Social and political climate • Media and pressure group activity OVER FOCUS ON SYMPTOMS Comparisons Attributions Responses Blame Pessimism
Irritable Bowel Syndrome Common digestive disorder Functional syndrome Traumatic life events, Personality disorders, Stress, Anxiety, Depression Somatization Not a psychological disorder Night-workers & Loners Psychology important in how symptoms are perceived and reacted to Can poor QoL Become a predictor of who will suffer in advance?
The UK Sheep Dipping Saga UK Sheep dipped twice yearly, and was compulsory 1984 – 1988 Organophosphate Pesticides (Ops) were the dip of choice & recommended by HSE & Government Routine sheep dipping is wet and messy work NOT usually an acute exposure Chronic and low level exposures more likely Non-specific symptoms alleviate 48 hours post-dip Dippers’ Flu Anxiety Depression Fatigue Aches & Pains Headache Fever Neurobehavioural problems (memory, concentration)
Headaches Anxiety Fatigue Depression Dippers’ Flu Memory loss Concentration General malaise “Unexplained Symptom Syndrome” The UK Sheep Dipping Saga
No Chronic Effects Ever Found • Symptoms should be acute & reversible, NOT chronic • Bio monitoring suggests symptoms should NOT occur • No good evidence of chronic effects (except after severe intoxication) • No reliable pattern to the symptoms reported • No pathological changes observed
Some Short Term Effects Exposed Farmers Control Subjects General cramp Sneezing Headache Cough Shiver Runny eyes Weak muscles Stiff muscles Sleep walking General ache Cognitive problems Pins and needles Judging distance Buzzing ears Numb toes Itchy skin Nose bleeds Flaky skin Earache Trouble sleeping Fever Flushes Aggression General weakness Coughing blood Jackson et al. 2001
The Fall Out Begins Farmers’ Response Government Response Seek media exposure Initially deny any effects Pressure groups formed Commission research Support groups formed Organize committees / reviews Search for “medicalisation” Question research results Search for compensation Minor policy decisions Commission more research
Why Did Farmers Become Ill ? Exposed to hazardous chemicals Opportunity to blame government Mistrust of government Lack of definitive information Attention from media Support of pressure groups * Isolation of farming life * Economic stress * Anti-chemical / pro-organic society * Farmers seen as intensive polluters * Unpopular with public *

New Approaches to Non-Specific Symptoms • Biopsychosocial approach could better explain other non-specific symptoms • Medical Disease model is limited • 1. Possibility of no objective measurable diagnostic criteria • 2. Contribution of many determinants of illness • 3. Qualitative & Quantitative methods • 4. Better acceptance among the physician community • 5. Quality of Life developed as ill-health predictor

New Approaches to Unexplained Symptoms • Accept there may be no objectively measurable diagnostic criteria • Accept contribution of many determinants of ill health • Both quantitative and qualitative research methods needed • Adjust our own mental models of accepting illness • Quality of Life important as an “outcome” & “contributor” to illness UNDERSTANDING ISSUES CONCERNING QUALITY OF LIFE MAY RESULT IN EXPLANATIONS FOR SUCH SOMATIC SYMPTOM SYNDROMES
