description: This catalog record includes detailed variable-level descriptions, enabling data discovery and comparison. The data are not archived at ICPSR. Users should consult the data owners (via the Roper Center for Public Opinion Research) directly for details on obtaining the data. This collection includes variable-level metadata of the 2015 poll Sports and Health in America, a survey from National Public Radio/Robert Wood Johnson Foundation/Harvard T.H. Chan School of Public Health conducted by Social Science Research Solutions (SSRS). Topics covered in this survey include:Sports participation in past yearExercise in the past yearImportance of sport/exerciseEffects of sport/exerciseFuture sport/exercise participationReasons for not participating in sport/exerciseSports participation in schoolDesire for child sports participationDesire to be professional athleteStopped playing sportsReasons for current sports participationChild healthChild sports participationSports participation with childEffects of child sports participationHope for child to be professional athleteChild exerciseObstacles to child sports participationPersonal healthSport/exercise injuriesHours of TVThe data and documentation files for this survey are available through the Roper Center for Public Opinion Research [Roper #31095185]. Frequencies and summary statistics for the 191 variables from this survey are available through the ICPSR social science variable database and can be accessed from the Variables tab.
description: The study was intended to estimate the share of American adults and children engaged in sports and exercise and the effect of sports on quality of life.
description: The study used phone numbers randomly generated from landline and cell phone samples, with an overlapping frame design, through Marketing Systems Group's (MSG) GENESYS sampling system. The sample consisted of four components: 1) Main RDD dual frame sample (N=1,400) included overlapping landline (n=670) and cell phone (n=730) frames of interviews with randomly selected adults, 2) Main RDD dual frame sport-participants oversample (N=575) included respondents from overlapping landline (n=205) and cell phone (n=370) frames who stated they participated in any sports during the previous year, 3) Sports-participant recruit oversample (N=198) included respondents who said they had participated in sports during a previous SSRS Omnibus survey and agreed to be called back, and 4) Middle/High-School parent oversample (N=333) included respondents who completed the SSRS omnibus survey in recent months and indicated they were parents (or legal guardians) of children living in their households, and that at least one child in the house was between the ages of 11 and 17.The questionnaire was developed by HORP, NPR, and RWJ in consultation with the SSRS project team. The questionnaire was also translated into Spanish.
description: The study dataset contains weight factors that should be employed in any data analysis. Typically weights are used in an attempt to assure that the survey sample more accurately represents the population. The weight variables in this study are TOTLWGT, QGRP1WGT, and QGRP2WGT.The survey data were weighted to adjust for the fact that not all survey respondents were selected with the same probabilities, account for the sample design and oversamples, and account for systematic nonresponse along known population parameters.For the Main Landline and Cell Phone RDD sample, the following weighting was involved: 1) adjustment for the likelihood of selection (base-weight), 2) post-stratification weighting using Iterative Proportional Fitting (or "raking") to reflect the distribution of the adult U.S. population along known population parameters.For all RDD components combined, the following weighting was involved: 1) the population incidence of sports participation was estimated from the weighted main-RDD sample to estimate the extent to which sports participants were oversampled.For all samples combined, the following weighting was involved: 1) propensity scoring for the sports recruits and parent callbacks, 2) estimating the share of the parent population, 3) sport participants and non-participants were then raked separately, 4) weight truncation ("trimming") to reduce variance, 5) proportionately combining the sport-participant and non-participant weighted sample, and 6) unique weights were created for split-samples (asked only sports or only exercise-related questions).
description: Response Rates: The combined response rate across all sample types was 17%.
description: The sample includes 2,506 national adults, age 18 or older across the 50 states and the District of Columbia, including oversamples of adults who said they played or participated in any sport in the past year and parents of junior high school, middle school or high school children.
