Drop-out from apprenticeship – an application of survival methods to grouped data- CLS working paper 1986/8

Dougal Hutchison looks at reasons for drop-out and finds that age at entry, region and marital status did not affect the probability of drop-out, but strong predictors were trade of apprenticeship, size of firm, educational level and whether the apprentice had signed articles.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, young adult, apprenticeship, education, qualifications, drop-out, trade, firm.

Event history and survival analysis in the social sciences- CLS working paper 1986/9

Dougal Hutchison illustrates the concepts involved in looking at discrete series of events in longitudinal studies, with reference to the NCDS cohort: additive models of survival time or hazard; proportional hazards; the semi-parametric approach and grouped distinct failure times.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, young adult, time series, survival analysis, Cox proportional hazards.

Social class changes in weight-for-height between childhood and early adulthood- CLS working paper 1986/6

Chris Power and C. Moynihan find that social class differences in the prevalence of overweight and obesity were found to be negligible in childhood but marked by early adulthood, with a greater percentage of overweight and obesity in lower social classes. This difference was three-fold among obese men and two-fold among obese women when respondents were classified on the basis of their own occupation.  But a longer-term effect of early class backgrounds also emerged. Children from manual backgrounds were more likely to become overweight and obese young adults (7 per cent of those with average weight-for-height at age 7) compared with their non-manual contemporaries (3 per cent).  They were also more likely to remain overweight or obese through to early adulthood.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, young adult, obesity, overweight, BMI, social class, gender.

Response to a national longitudinal study – policy and academic implications in the study of change- CLS working paper 1986/7

Dougal Hutchison looks at reasons (other than non-response) why final sample sizes in longitudinal research may be much lower than the target population of the study: for instance, restrictions of analyses to sub-populations, and losses in the course of operationalizing concepts.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, young adult, attrition, bias, loss-to-follow-up, sub-populations, item non-response,

Leaving the parental home – an analysis of early housing careers- CLS working paper 1986/4

Gill Jones’s analysis of early housing careers in the NCDS 1958 cohort looks at factors such as movement from school to work, family formation and the effects of social class and gender on early housing decisions in the context of  leaving the parental home.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, young adult, housing, parental home, social class, gender.

Stratification in youth- CLS working paper 1986/5

Gill Jones’s research looks at what has happened to young people aged 23 in the NCDS 1958 cohort since they left full-time education, looking at notions such as youth as a transition, and the place of young adults in the social structure.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, young adult, housing, social class, gender.

Effects of ability grouping in secondary schools in Great Britain- CLS working paper 1986/3

Alan C. Kerckhoff’s research compares those in the NCDS 1958 cohort who have been  educated in ability groups with those who have not.   Covariates are social background, parental influences, school influences, and contingencies such as residential moves from birth to age 11.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, education, streaming, ability

Health and social mobility during the early years of life- CLS working paper 1986/2

Chris Power,  Ken Fogelman and John Fox describe a DHSS-funded project concerned with relationships between social class, social mobility and health during the early years of life.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, social class, SES, social mobility, health, young adult.

Report on the longitudinal exploitation of the National Child Development Study in areas of interest to the DHSS- CLS working paper 1986/1

Mildred Blaxter reviews the value of all the longitudinal research done so far on the NCDS cohort, under the following broad categories:

Social mobility, inequality and health;

Social and geographical mobility, the environement and health;

Stress in childhood;

The long-term effects of adverse factors at birth;

The sequellae of developmental and behavioural problems;

The conseqeuences of labelling;

The predictive value of different assessments;

The natural history of specific conditions;

The study of special sub-groups;

Accidents;

Health and employment/unemployment;

Emotional problems and health;

Alcohol consumption;

Smoking;

Intergenerational analyses.

A longitudinal study of alcohol consumption amongst young adults in Britain, Part III: childhood and adolescent characteristics associated with drinking behaviour in early adulthood- CLS working paper 1985/15

In this third piece of research in a 3-part series, Mayer Ghodsian analyses the relationship between alcohol consumption early-adulthood (age 23) and its associations with a wide range of characteristics during childhood and adolescence in the NCDS 1958 cohort.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, alcohol, intoxication, drinking, adolescence, young adult.

A longitudinal study of alcohol consumption amongst young adults in Britain, Part II: a national longitudinal study of alcohol consumption between the ages of 16 and 23- CLS working paper 1985/14

In this second piece of research in a 3-part series, Chris Power and Mayer Ghodsian analyse the relationship between alcohol consumption in adolescence (age 16) and early-adulthood (age 23) in the NCDS 1958 cohort.

Keywords: 1958 birth cohort, NCDS, National Child Development Study, alcohol, intoxication, drinking, adolescence, young adult.

A longitudinal study of alcohol consumption amongst young adults in Britain, Part I: alcohol consumption and associated factors in young adults in Britain- CLS working paper 1985/13

In this first piece of research in a 3-part series, Chris Power analyses the personal, social and economic characteristics of young adults in relation to alcohol consumption, using the NCDS 1958 cohort follow-up at age 23.
