Simmons Longitudinal Study: Adaptation and Development Across the Lifespan [New England, United States], Age 26 Data, Wave 7, 1998 (ICPSR 24866)

Principal Investigator(s): Reinherz, Helen Z., Simmons College. School of Social Work


The Simmons Longitudinal Study (SLS) is a community-based study that has prospectively traced the life course of a single-aged cohort from childhood (age 5) to adulthood (age 26). Data were collected from multiple informants at seven major time points: age 5 (1977), age 6 (1978), age 9 (1980-1981), age 15 (1987), age 18 (1990), age 21 (1993-1994), and age 26 (1998). Since its inception in 1977, the SLS has utilized a multidisciplinary, multimethod approach, with the dual goals of: (1) tracing the development and course of academic difficulties, behavior problems, and psychopathology; and (2) identifying factors that promote health functioning from early childhood (age 5) to adulthood (age 26). The SLS has consistently emphasized the identification of modifiable social and environmental risk and protective factors that can be targeted directly in prevention and intervention programs. To date, SLS has published 50 journal articles and 9 book chapters. The original study group was comprised of every child who entered kindergarten in the fall of 1977 in one public school district in a northeastern town in the United States. For this wave of the study, Wave 7, respondents were 26 years old in 1998. In addition to diagnostic information, participants reported on their current employment, functioning, and family relationships. In young adulthood, many members of the study group reported satisfaction with their education, careers, and families. For both the respondent and parent/relative interviews, interviewer observations were obtained.

Sample:    (1) The original 1977 sample included all youth registering for kindergarten in one public school system in a working class community in Massachusetts. The racial composition and gender division of the original sample were representative of the population of Massachusetts at that time. The sample included approximately equal numbers of males and females, and almost all (98 percent) were Caucasian. For information in regard to "Sample Retention" and "Effects of Sample Attrition," please review the ICPSR codebook available with this collection. (2) A telephone interview was conducted with the Parent/Relative only. If the respondent lived out of the area, a telephone interview was conducted rather than a face-to-face interview.

Mode of Data Collection:    face-to-face interview, self-enumerated questionnaire, telephone interview

Extent of Processing:   ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure.
