It is common wisdom that death of a spouse can lead to health deterioration of the partner left behind. Is common wisdom right or wrong in this case? To investigate, Maddison and Viola (1968) measured the degree of health deterioration of 132 widows in the Boston area, all of whose husbands had died at the age of 45-60 within a fixed six-month period before the study. A total of 28 of the 132 widows had experienced a marked deterioration in health, 47 had seen a moderate deterioration, and 57 had seen no deterioration in health. Of 98 control women with similar characteristics who had not lost their husbands, 7 saw a marked deterioration in health over the same time period, 31 experienced a moderate deterioration of health, and 60 saw no deterioration. Test whether the pattern of health deterioration was different between the two groups of women. Click to download the data in your preferred format.

Transcribed Image Text:**Investigating Health Deterioration After Spousal Loss**
It is common wisdom that the death of a spouse can lead to health deterioration of the surviving partner. To explore whether this holds true, Maddison and Viola (1968) conducted a study to measure the degree of health deterioration among 132 widows in the Boston area. All their husbands had died at the age of 45-60 within a fixed six-month period prior to the study.
In their findings:
- 28 of the 132 widows experienced a marked deterioration in health.
- 47 widows experienced a moderate deterioration in health.
- 57 widows had no deterioration in health.
A control group of 98 women with similar characteristics, but who had not lost their husbands, was also observed:
- 7 of these women experienced a marked deterioration in health.
- 31 experienced a moderate deterioration in health.
- 60 reported no deterioration.
The study aims to test whether the pattern of health deterioration was different between the two groups of women.
