Marital Instability Over the Life Course [United States]: A Five-Wave Panel Study, 1980, 1983, 1988, 1992-1994, 1997

Data Archive > U.S. Surveys > General Population > National > Other National Surveys > Summary

To examine the causes of marital instability throughout the life course, five waves of data were collected between 1980 and 1997 from married individuals who were between the ages of 18 and 55 in 1980. Information collected in 1980 (Wave I) focused on the effects of wives' participation in the labor force on marriage and marital instability. Measures predicting marital instability and divorce and assessing marital quality were developed. Variables include information on earnings, commitment to work, hours worked, and occupational status. The focus of Wave II, conducted in 1983, was to link changes in factors such as economic resources, wife's employment, presence of children, marital satisfaction, life goals, and health to actions intended to dissolve a marriage, such as divorce and permanent separation. Information on adjustment to marital dissolution, relationship with in-laws, size of home, parents' employment, use of free time, club membership, child-care arrangements, and responsibility for chores was gathered. Wave III, collected in 1988, further examined the impact of changes in employment, economics, and health on marital relationships. Questions were asked about divorce and remarriage, investment of energy and resource use in the care of aging parents and dependent offspring, asset value, awareness of aging, mental health issues, and history of disease. In 1992, a fourth wave of data was collected to look at changes in employment, economics, and health. Questions were asked about retirement issues, family structure, and the impact of caring for aging parents while at the same time caring for dependent offspring. Data were also collected in 1992 and 1994 from adult offspring who were living in the household in 1980 and had reached age 19 by 1992, thus providing parallel measures with their parents regarding the quality of parent-child relationships, attitudes, and support along with exploring the impact of childhood experiences on the transition to adult life. In 1997, the fifth wave was collected and interviews were conducted with a second sample of adult offspring (N=202) along with second interviews of offspring selected in 1992 (N=606). Wave 5 also examines the relationship between marital quality and stability and how it relates to changes in marital quality later in life. Among the variables included in all five waves are age, sex, educational attainment, marital status and history, attitude toward divorce, number of children, religious affiliation, and income level.

Collection Procedures
Waves I, II, and III

Participants were first interviewed by telephone in the fall of 1980. Spouses were not interviewed. Random digit dialing was used to select the sample. Among eligible households the response rate was 65%. Three percent were partial interviews, 15% refused, and 17% could not be reached. In 1983, the response rate was 78% and in 1988, 84%. The re-survey in 1983 yielded 1,578 completed interviews and reliable information on marital status of another 150 individuals. In 1988 1,341 interviews plus reliable marital information on another 94 people were obtained. Because divorce was the central focus of the investigation, interviewers were instructed to obtain information on the individual's marital status even if they could not complete the interview or reach the individual. The marital status information could then be used when predicting marital instability from previously obtained interview data.

Wave IV

To maintain the integrity of the panel, respondents were tracked in the spring of 1989 and again in the spring of 1991. In April of 1989 and February of 1991 letters were sent to all respondents, giving them a progress report on the study. The letters were sent with "Address Correction Requested" so that study staff were informed about those individuals who had changed addresses or for whom the letter could not be delivered. Those individuals were tracked and lists of addresses and phone numbers updated.

Everyone who was reinterviewed in 1992 who had offspring 19 years of age or older who resided in the household in 1980 were asked to give us the name and phone number of a child. In cases where there was more than one eligible child, a random procedure was used to select the child to be included in the study. In households with two eligible children, the name, address and phone number of the second offspring was also obtained. In households with three or more eligible children, a second child was selected at random and the name, address, and phone number requested. We interviewed the second child when it was not possible to obtain an interview with the first. We felt it was better to obtain information on one child than none. We obtained phone numbers on 537 first selected and 299 second selected offspring. Six percent of the interviews are with offspring other than the first selected individual. Of the 1,341 people who were interviewed in 1988, we succeeded in reinterviewing 1,193 (89%) of the adults. Among those interviewed, 625 had children 19 years of age who resided in the household in 1980. Eighty-eight (14%) elected not to provide the name and phone number of the offspring. Of the 537 names of offspring provided by parents, interviews were
obtained from 471 (88%) of them.

Wave V

To maintain the integrity of the panel, respondents were tracked in the fall of 1993 and again in the fall of 1994. Letters were sent to all respondents giving them a progress report on the study (see Appendix C). The letters were sent with “Address Correction Requested” so that study staff were informed about those individuals who had changed addresses or for whom the letter could not be delivered. Those individuals were tracked and lists of addresses and phone numbers updated. Offspring of the panel respondents who were interviewed in 1992 were also tracked in the fall of 1993 and 1994. Offspring respondents were sent a letter in 1995 updating them on the study as well as a short survey asking about changes in their work/family life since 1992. A follow-up postcard was sent to those respondents who had not yet returned the short survey.

Respondents who were re-interviewed in 1997 who had offspring 19 years of age or older who resided in the household in 1980, and who did not have offspring who were interviewed in 1992, were asked to give us the name and phone number of a child. In cases where there was more than one eligible child, a random procedure was used to select the child to be included in the study. In households with two eligible children, the name, address and phone number of the second offspring was also obtained. In households with three or more eligible children, a second child was selected at random and the name, address, and phone number requested. We interviewed the second child when it was not possible to obtain an interview with the first. We felt it was better to obtain information on one child than none. We obtained phone numbers on 250 first selected and 119 second selected offspring. Three percent of the interviews are with offspring other than the first selected individual. Of the 1,193 people who were interviewed in 1992, we succeeded in re-interviewing 1,077 (90.3%) of the adults.
Sampling Procedures
The population sampled was all husbands and wives in households in the contiguous United States in which both spouses were present and under the age of 55 and who had access to a telephone. A clustering technique was used to reduce selection costs. It was estimated that the respondents were sufficiently dispersed geographically so as not to create a design effect requiring attention in the analysis of the data. An additional random procedure was used to select a couple if more than one lived in the household and to select the husband or wife.

Sample Representativeness and Weighting
Using Census data, the investigators evaluated the sample on the following background characteristics: age, race, sex, household size, presence of children, home ownership, husband's education, region, and metropolitan residence. The sample is comparable to the national distribution of married individuals, husbands under 55 on the following characteristics: husband's age, wife's age, race, household size, tenure, region, and presence of children. The sample does have the biases in sex and education expected in survey research; the sample is more likely to be female (59% versus 52% for the population), and better educated (30% with a bachelors degree versus 24% for the population). Because of the higher refusal rates in metropolitan areas only 63% of the sample, compared with 74% of the nation, comes from standard metropolitan statistical areas. This disparity occurs in all areas but the south. To increase the generalizability of the survey, the sample was weighted for metropolitan residence by region.

According to the investigators, attrition in the second and third waves influences the representativeness of the sample only slightly. Table 5 in Appendix 1 shows the 1980 characteristics of those reinterviewed in 1983 and 1988. Attrition occurred among those who were 14-24 years old, black, those with Spanish origin, males, individuals from three person households, renters, those without any college, people from the south, those with children under 6, and those living in metropolitan areas. Out of 54 comparisons between 1980 and 1988 characteristics, 6 were more than by 3 percent and 41 of the comparisons were below 2.5 percent. Probit analysis was used to test whether some demographic variables (age, sex, home ownership, education, presence of children) and five indicators of marital quality (happiness, disagreement, interaction, problems, divorce proneness) affect the probability of not being included in the second and third wave. Home ownership and educational attainment were the only statistically significant predictors of a non-interview. Renters and those with lower educational attainment are more likely to drop from the panel. The panel remains fairly representative of the target population.

Marital Instability Scale
These indices of marital instability are based on 27 items asked of people who are married. The initial development of the scale is described in detail in the following publications:

Booth, Alan, David Johnson, and John N. Edwards. 1983. "Measuring Marital Instability." Journal of Marriage and the Family 45: 387-393.

Edwards, John N., David R. Johnson, and Alan Booth. "Coming Apart: A Prognostic Instrument of Marital Breakup." Family Relations 36: 165-170.

Johnson, David R., Lynn K. White, John N. Edwards, and Alan Booth. "Dimensions of Marital Quality: Toward Methodological and Conceptual Refinement." Journal of Family Issues 7: 31-49.

The scale was revised slightly in 1984 and it is that revision that is available for all three years. Higher scores indicate greater marital instability. The variable was logged to bring the distributional quality more into line with the assumptions needed for multiple regression.
Marital Problems Scale
A summated scale using 13 items indicating presence of marital problems because either or both spouses: 1) gets angry easily; 2) gets easily hurt; 3) is jealous; 4) is domineering; 5) is critical; 6) is moody; 7) won't talk to the other; 8) has sexual relationship with others; 9) has irritating habit; 10) is not home enough; 11) spends money foolishly; 12) drinks or uses drugs; and 13) has been in trouble with the law. Higher scores indicate greater marital problems.
Marital Happiness Scale
A summated scale using eleven items reflecting amount of happiness with: 1) extent of understanding received from spouse; 2) amount of love received; 3) extent of agreement about things; 4) sexual relationship; 5) spouse as someone who takes care of things around the house; 6) spouse as someone to do things with; 7) spouse's faithfulness; 8) evaluation of marriage as very happy, pretty happy, or not too happy; 9) compared to other marriages, respondent's is better, same, or not as good; 10) comparing marriage to 3 years ago, it is getting better, staying the same, or getting worse; and 11) strength of feelings of love respondent has for spouse.
Marital Interaction Scale
A summated scale using five items: 1) eat main meal together; 2) go shopping together; 3) visit friends together; 4) work around home together; and 5) go out together. Scale has possible values from 5 to 20. Higher scores indicate greater interaction.
Sex Roles Scale
A summated scale using seven items: 1) wife's most important task: caring for children; 2) husband should earn higher pay than wife; 3) husband shouldn't worry if wife gone overnight in connection with job; 4) if wife works full-time, husband should help with housework; 5) if jobs scarce, wife shouldn't work; 6) working mothers can have just as good of a relationship with kids; and 7) even if wife works, husband should be main breadwinner. Response categories were: 1) strongly agree; 2) agree; 3) disagree; and 4) strongly disagree. Higher scores indicate more traditional values.
Marital Disagreement Scale
A summated scale using the following items: 1) disagreements over share of housework done by respondent; 2) frequency of disagreements with spouse; 3) number of serious quarrels with spouse within last two months; and 4) arguments involving physical abuse. Scale values range from 0 to 12. Higher scores indicate greater disagreement. The variables were z-scored and added together.
Wife's Job Commitment Scale
A summated scale using four items:

1. Wife works because she wants a career
2. Wife works for a feeling of accomplishment
3. Wife works because she wants financial independence
4. Wife's work preference: full-time, part-time, none
