- (From the chapter) Our chapter is divided into three sections. The first section includes an overview of developmental approaches to interdependent data. The limitations of previous analytic strategies will be considered, followed by a discussion of procedures that address these limitations. Although these points apply to research on all close relationships, we will limit our examples to research on peers. Our particular focus is peer similarity, which encompasses selection and socialization influences. The second section describes a novel adaptation of the Actor-Partner Interdependence Model (APIM; Kashy & Kenny, 2000; Kenny & Cook, 1999) to longitudinal data on friendship homophily. Conventional APIM procedures are well suited to describe concurrent patterns of association; our modified structural equation modeling approach utilizes multiple group analyses with indistinguishable dyads to shed light on socialization and selection effects across time. The third section describes a new statistical application designed to estimate peer group homogeneity from longitudinal data. The SIENA statistical software package (Snijders, Pattison, Robins, & Handcock, 2006) simultaneously models selection and socialization effects over time. We describe how to partition variance into parameters that ascribe similarity to networks, dyads, and individuals. We close with a call for developmental scholars to take seriously the need to incorporate interdependence into the design of new research.

Tidskriftsartikel (refereegranskat)abstract
- Selection and socialization have been implicated in friendship homophily, but the relative contributions of each are difficult to measure simultaneously because of the nonindependent nature of the data. To address this problem, the authors applied a multiple-groups longitudinal actor-partner interdependence model (D. A. Kashy & D. A. Kenny, 2000) for distinguishable dyads to 3 consecutive years of intoxication frequency data from a large community-based sample of Swedish youth. Participants, ranging from 12 to 18 years old (M = 14.35, SD = 1.56) at the start of the study, included 902 adol escents (426 girls and 476 boys) with at least one reciprocated friend during at least one time point and 212 adolescents (84 girls and 128 boys) without reciprocated friends at any time. Similarity estimates indicated strong effects for selection and socialization in friends' intoxication frequency. Over time, younger members of these dyads had less stable patterns of intoxication than older members, largely because younger partners changed their drinking behavior to resemble that of older partners.
