Introduction

• Living alone has become a common phase in the lifecourse with one person households now making up a third of all households in Britain

• This is a rising trend in western societies

• Proportion of 16-59 year olds living alone in Britain has trebled from 5% in 1971 to 16% in 2002

Introduction

• Increase of people who live alone has many social, economic and policy implications

• The trends are regarded as symbolic of excessive individualism (Bauman 1995).

• Also optimistically as a democratisation of personal life


Introduction

• Increase of living alone leads to more housing demand, more poverty, social inequality, care demand, decrease of fertility

• And health problems which are not widely researched.


Does living alone matter?

• Living alone is a type of social isolation

• Social isolation may be detrimental to individuals’ mental health

• Faris, (1934) “Any form of isolation that cuts the

person off from intimate social relations for an extended period of time may lead to this form of mental disorder”.



• People living alone are less likely to develop close personal relationship and the same level of commitment to other people than people who living together

• Persons living alone much less likely to be engaged in mutual obligations and mutual reinforcement of a primary type, particularly on a daily basis



• Persons living alone less likely involve emotional gratification and personal satisfaction.

• Although individually people living alone may be better off they are worse off because of pooling effects for people living as a family

• Living alone more likely to have pathological behaviour, smoking, drinking



• However, social integration involves not only benefits but costs

• Social relations can be a source of emotional, physical, and financial tension (House, et al 1988)

• At an extreme, of all social ties, family relations are most likely to be negative and damaging to individual well-being.



• Marriage has been shown to have protective effects on people’s health

• Married people enjoy better mental health than other demographic groups (Lillard & Panis, 1996)


Previous studies

• Supportive – Smith et al 2005; Rogers et al 2000;

Denton & Walters, 1999; Hughes & Waite 2002; Joutsenniemi et al 2006

• Unsupportive– Hughes & Gove 1981; Denton & Walters

1999


What will this study do?

• This research focuses on the effect of living alone on mental health

• Longitudinal data


Research questions

• Does living alone affect mental health?

• Does living alone affect mental health independent of marital status?

• Does the transition into living alone affect mental health?

• Are there gender differences in the effect of living alone?


Data

• British Household Panel Survey (BHPS)• A national representative sample• Prospective samples-interviewees are

followed annually from 1991• All household members over 16 are

interviewed• 1991-2003, 5000 households and

10000 people


Measurement of mental health

• General Health Questionnaire (GHQ)• 12 questions like

– Have you recently:• Lost much sleep over worry?• Felt constantly under strain?• Felt you could not overcome your difficulties?• Been feeling unhappy and depressed?• Been losing confidence in yourself?• Been thinking of yourself as a worthless person?


Measurement of mental health

• We use the caseness method, each response is coded 0, and 1

• Total 12 items end up with 0 to 12• A dichotomous variable is

constructed with a threshold of 4 Individuals aged 16 to 64 are included

in our study

Modelling issues

• Longitudinal data allow us to – Control unobserved heterogeneity

• Ability to cope with stress• Childhood experience

– Study transitions between different living arrangements


Modelling issues

• Fixed effect logistic models for models of being alone

• Logistic models for effects of transition into living alone (excluding never married or never cohabiting)

• Control for age, household income, urban rural areas of residence, education, employment status, smoking, number of friends, and region of residence

Conclusions

• Being living alone tends to negatively affects mental status for men but not women

• Being living alone does not have independent effects on mental health from marital status

• Transition into living alone has strong effects on mental health and increases risks of mental disorders in short-term


Future studies

• Better methodologies in tackling endogeneity using SEM modelling or 2SLS

• Dynamic panel models taking account of state dependency

• Increase sample size by incorporating more data from the latest waves

• More analysis of duration effects
