The University of Buffalo Adolescent and Family Development Project (AFDP) includes a community sample of adolescents assessed in a 9-wave longitudinal study between 2007 and 2017. The 387 adolescents were 11-12 year old children at recruitment and were assessed annually. The data provide an opportunity to examine risk and protective factors from multiple levels of influences (individual differences, family, peers, community) that might contribute to adolescent substance use in order to inform the development of comprehensive preventive interventions for at-risk youth. The project was largely focused on understanding the development of an internalizing pathway to initiation and escalation of substance use, and eventual development of use-related problems. This was done by examining: 1) the intersection of externalizing and internalizing problems, 2) peer context and use-related motives as a potential mediating mechanism, and 3) whether motivational aspects of personality moderated the proposed mediational paths. Also of interest was whether risk for an internalizing pathway to substance use varied by chronological age or stage of use.
This collection is organized into 13 data parts. Waves 1 through 3 and Waves 7 through 9 each contain 2 datasets pertaining to either a child (DS1, DS3, DS5, DS8, DS10, DS12) or caretaker (DS2, DS4, DS6, DS9, DS11, DS13) interview. All child interview data from Waves 4 through 6 are contained in DS7. Various demographic information, such as age, gender, race, and ethnicity, is also included in the data.

Waves 1, 2, and 3 Procedures
Adolescents and their parents were interviewed in university research offices. Before the interviews began, parents were asked to give consent and adolescents were asked to give assent. Trained research assistants interviewed parents and adolescents in separate rooms to enhance privacy. Data collection included both laboratory tasks as well as questionnaires assessing a wide range of family, peer, individual level risk and protective factors for adolescent drug use. Items from the structured questionnaires participants completed were read aloud and then entered by the interviewer. Items containing sensitive information (e.g., substance use items) were entered by the participant. Assessments took approximately 2.5 to 3 hours. Families were compensated $75, $85, and $125 dollars for Waves 1 through 3, respectively. Procedures and measures for Waves 2 and 3 were identical to those at Wave 1 with a few minor adjustments. Approximately 12 months (+/- 1 month) after the Wave 1 (and Wave 2) assessment the target child and caregiver were contacted for a subsequent data collection.
Waves 4, 5, and 6 Procedures
Waves 4 through 6 consisted of a brief telephone-based audio-Computer-Assisted Self-Interview (CASI) survey of substance use that took 10 to 15 minutes to complete. Parents provided consent over the phone and were given a phone number and PIN for their adolescent to use. Assent from the adolescent was obtained at the initiation of the audio-CASI survey. Procedures and measures for Wave 5 and 6 were identical to those at Wave 4 with a few minor adjustments. Prior to the year anniversary of the Wave 5 audio-CASI, a packet was sent to the family inviting them to participate in the Wave 6 audio-CASI. The packet included an informational letter, consent/assent forms, and return envelopes. The research team then followed up with a phone call. Once the assent/consent were obtained, the child was provided with a phone number and code to complete the interview. Upon completion of the survey, the child selected a gift card option ($15), which was mailed to them. Substance use items included in the audio-CASI were adapted from the National Youth Survey. Some adolescents preferred to fill out paper and pencil surveys and mail them to our office.
Waves 7, 8, and 9 Procedures
Procedures at Waves 7, 8, and 9 closely aligned with those at Waves 1, 2, and 3. Participants (target adolescent) and their caregivers completed annual interviews in university research offices. Considering the age of the participants at these waves, a number of participants had relocated out of the area. To retain these individuals, participants were provided with an opportunity to complete the questionnaires remotely. Assessments took approximately 2.5 to 3 hours. Target adolescents and caregivers were provided $125 and $40, respectively, at Wave 7. This amount incremented $10 and $5 dollars, respectively, in subsequent waves.
Participants were recruited utilizing a random-digit-dial sample of listed and unlisted telephone numbers generated for Erie County, New York. Erie County is a large geographical area that encompasses mostly urban and suburban areas, but also some rural areas. Adolescents were eligible at recruitment if they were between the ages of 11 and 12, and did not have any language or physical disabilities that would preclude them from understanding or completing the assessment. The final sample included 387 families (a caregiver and child from each).
