The survey data was collected through 8 waves of data collection over a four year period (see <\/span>Table 5: Basic and Network Survey Questionnaires<\/span><\/a> for dates when data was collected) using Qualtrics software to design and implement the survey instrument and to collect online answers from participants.\u00a0 Collected data was exported into Stata (a statistical and data processing application) for cleaning and processing, and then merged with previous cleaned data waves.\u00a0 The resulting 8 waves of merged survey data contain for each study participant information on variables from each of the surveys that they completed.\u00a0\u00a0\u00a0<\/span><\/p>\n

722 students took at least one of the surveys, 698 of whom enrolled in the study.\u00a0 Some students took the survey and filled out consent forms but decided not to participate.\u00a0 We include their limited data here because if they were named in network surveys by study participants they receive a five digit <\/span>case number<\/span><\/i> code indicated we have survey data on them.\u00a0\u00a0\u00a0<\/span><\/p>\n

The data file exists as both a Stata .dta file and a raw .csv file. A Stata generated codebook was created (see <\/span>Basic Survey Codebook<\/b>).\u00a0 There are over 3000 variables.\u00a0 The file is organized by wave. A suffix\u00a0 \u201c_N\u201d is attached to a variable name indicating which of the 8 survey waves the variable\u2019s values come from.\u00a0 Within waves, variables are listed in the data file roughly in the order in which questions were asked in the survey.\u00a0 All non-identifying raw variables are contained in this file, along with numerous constructed variables from the original raw ones.\u00a0 The values of constructed variables for a set of raw variables usually follows the set of raw variables from which they were constructed.\u00a0 For example after the 44 items in the Big Five Personality Inventory there are the 5 constructed personality measures: Extraversion, Agreeableness, Conscientiousness, Neuroticism and Openness.\u00a0<\/span><\/p>\n

Copies of the Qualtrics survey instruments for each wave are in the<\/span> Documentation Section<\/b>.\u00a0 <\/span>Table 5: Basic and Network Survey Questionnaires<\/span><\/a> provides links to the .pdf and MS Word .doc version of each survey.\u00a0<\/span><\/p>\n

Not all variables are asked in each wave.\u00a0 <\/span>Table 4:\u00a0 Basic Survey Questions by Wave<\/span><\/a>, contains information on which sets of variables were asked in which waves.\u00a0 Variable names generated by Qualtrics begin with \u201cQ\u201d and have the form \u201cQn.m\u201d where \u201cn\u201d refers to the section bloc of the survey and \u201cm\u201d for the question\u2019s number within that block.\u00a0 These names appear in the .doc and .pdf copies of the survey. During data cleaning using Stata, all names were changed to meaningful <\/span>variable names <\/span><\/i>indicating what the variable measures.<\/span>\u00a0 Variable name labels<\/span><\/i> for the names were added and include information on the question (including sometimes Qualtrics question numbers).\u00a0 This way users can go to the .pdf or .doc file for a specific survey and look up the exact question for the variable of interest. \u00a0 Users can also use <\/span>Table 4<\/span><\/a>\u00a0 to identify where in the survey specific questions are located. \u00a0 We employed many mental health and social-psychological scale systems developed by others. <\/span>Table 6: Basic Survey Scales<\/span><\/a> contains links to documents with the items we used and the methods for scale construction.\u00a0\u00a0<\/span><\/p>\n
