  3. Measuring Life Change www.psychlotron.org.uk • Holmes & Rahe(1967) • List of life changes rated (judged by a panel) for degree of readjustment required e.g. • Death of spouse – high readjustment - 100 • Holiday – low readjustment - 13 • Adding up scores for changes during a given period (6m) gives the LCU score

  4. Life Change & Stress www.psychlotron.org.uk • Rahe et al (1970) • Study of relationship between life change and general health • LCU scores obtained using SRRS • Health scores generated from doctors’ records • Correlation between SRRS and illness scores was +0.118 • Small, but unlikely to be a chance result

  5. Life Change and Stress www.psychlotron.org.uk • Thomas et al (1997) • Increased LCU scores predicted increased mortality risk in heart patients • Rosengren et al (1993) • Higher LCU scores associated with higher mortality in elderly PPs

  6. Life Change and Stress www.psychlotron.org.uk • Individual differences • Impact of CLEs likely to be mediated by e.g. personality, coping style • Some events (e.g. divorce) may be perceived differently by different people • Correlational & retrospective data • Do pps have an accurate recall of events/illnesses? • Does being ill make certain CLEs more likely?
