Relationships in middle childhood provide important skills for developing and maintaining peer relationships in early adolescence. Experiences with warmth (i.e., friendly, affectionate behaviors toward others) in particular seem to facilitate the successful navigation of later interpersonal relationships (e.g.,
One feature that sets the current generation of adolescents apart from previous generations is their wide access to digital communication. Unlike face-to-face communication, digital communication can occur anywhere that adolescents have access to the Internet or smartphones. Adolescents heavily use text messaging to communicate with peers, and their text messaging communication is rich with emotional tone conveyed in relatively few words (
The present research investigates links between experiences with warmth in middle childhood and affective states and disagreeable interactions within text-based digital communication in early adolescence. Below we discuss the important role that digital communication plays in early adolescence and describe theoretical frameworks to help explain the transmission of warmth in middle childhood to later text-messaging communication. Because parents and peers likely both play a role in socialization, we introduce a statistical model that helps to disentangle these different sources of behavior and thus provide a more nuanced picture of how warmth in middle childhood comes to be related to text-message communication.
Common forms of digital communication include short message service (aka text-messaging) via mobile phone, instant-messaging (IM) using services such as Snapchat and Facebook messenger, and posts or announcements (aka microblogging) using social networking websites such as Twitter, Instagram, and Facebook. These digital communication forms differ with regards to the typical content exchanged (e.g., text for Twitter, photos for Instagram) and the size of the audience (e.g., whereas Twitter can reach a large audience, IM is generally restricted to one person at a time). Unlike social networking website communication, text-messaging via mobile phone generally involves dyadic exchanges of written content.
Adolescents report preferring text messaging as a way of communicating with friends, even more than face-to-face interactions (
Both the frequency and content of adolescents’ text messaging relate to psychological adjustment. Self-report and observational studies of text messaging show that frequency of texting relates to externalizing symptoms (
Although negative text messaging content may be associated with maladjustment, frequency of text messaging may also relate positively to the quality of adolescents’ friendships. For a sample of adolescents in the Netherlands, self-reported online communication (e.g., IM, e-mail) was related to perceived closeness with friends (
We define warmth in the present research as interpersonal behavior characterized by positive valence and benevolence. Whereas we consider higher levels of warmth to involve nurturing and agreeable behavior (e.g., friendliness, sympathy, and cooperativeness;
Expressions of warmth and quarrelsomeness typically invite similar behaviors (warmth and quarrelsomeness, respectively) from others (see, e.g.,
Much of the available empirical evidence on links between offline and online behavior supports a perspective called co-construction theory, that “adolescents are psychologically connected to their online worlds similarly to their offline worlds” (
Co-construction theory therefore suggests that warmth in text messaging might follow from warmth in earlier, offline relationships.
The development of early adult romantic relationships (DEARR) model (cf.
One useful design that can be used to assess multiple relationships is the one-with-many (OWM) design. In this design, a focal individual is tied to several partners and those several partners are tied only to the focal individual. When working with the OWM, a distinction is made between the “one” (i.e., the focal person who has ties to several partners) and the “many” (i.e., the many partners who have ties to the focal person). Moreover, data can be gathered from the one (e.g., the focal person’s expressions of warmth toward all the partners), the many (e.g., the partners’ expressions of warmth toward the focal person), or both (in which case the design is said to be reciprocal). It is also possible that the “many” can be meaningfully distinguished (e.g., by role such as parent vs. friend). The OWM design differs from the more widely known round-robin designs because the partners (or the “many”) do not interact with one another. Nevertheless, the underlying model of interpersonal behavior is the same.
When data are collected from a reciprocal OWM design with distinguishable members—as would be the case when target children interact with their parents and peers, but the parents and peers do not interact with each other—variance partitioning analyses based on the SRM can illuminate the extent to which target children’s expressions of warmth toward their parents and friends are due to their dispositional tendencies to express warmth toward others (i.e., the target children’s actor effects) or the unique relationships they have with their parents and friends (i.e., the child-to-parent and child-to-friend relationship effects). These analyses can further determine the extent to which parents’ and friends’ expressions of warmth toward the target children are due to the target children’s dispositional tendencies to elicit warmth from others (i.e., the target children’s partner effects) or the unique adjustments that parents and friends make to the target children (i.e., the parent-to-child and friend-to-child relationship effects). However, because there are only three people and the parents and peers do not interact with each other, there are not enough data to estimate the group mean effect or the actor and partner effects for the parents and peers. This approach nevertheless enables a reasonably sophisticated understanding of how experiences with parents and peers contribute to later outcomes.
In addition, OWM analyses can provide insight into whether target children’s dispositional tendencies to express and receive warmth are connected (i.e., generalized reciprocity), as well as whether unique expressions of warmth are reciprocated within the parent–child and friend–child relationships (i.e., parent–child and friend–child dyadic reciprocity). Because research on affective constructs generally finds stronger reciprocity in within-generational (e.g., siblings) than between-generational relationships (e.g., parent–child;
The current research uses a prospective multimethod design across 8 years to investigate linkages between actual behavior in middle childhood and early adolescence. Unlike other studies, we include both parents and peers, which permits us to better understand how unique features of these relationships contribute to the manifestation of warmth over and above children’s dispositional tendencies to express and receive warmth. Moreover, by including both the child’s parent and friend in the same study, we are able to evaluate whether connections between observed warmth in middle childhood and digital communication in adolescence are better explained by behavioral continuity or socialization mechanisms.
With this in mind, our research is guided by the following sets of research questions:
Procedures were approved for the project, Social Aggression: Precursors and Outcomes, by the Institutional Review Board at the University of Texas at Dallas (IRB# 07–36). Participants included 218 typically developing children (and their parents and peers) who were involved in an ongoing longitudinal study examining the antecedents and consequences of social aggression (
Target children were asked to bring their parent and a same-gender, similarly aged friend to the laboratory in the fourth (n = 205), fifth (n = 195), sixth (n = 188), and seventh (n = 173) grade. Parents primarily consisted of target children’s mothers (fourth: 94.3%; fifth: 94%; sixth: 94.7%; seventh: 94.3%). To ensure that latent variables capturing features of the parent–child relationship were comparable across waves, we excluded those participants who did not bring the same parent to the lab visits. Although target children always brought a parent to the visit, they did not always bring a friend (6.9% of participants did not bring a friend in fourth grade; 20.2% in fifth grade; 29.8% in sixth grade; and 38.2% in seventh grade). The majority of participants (72.9%) did not bring the same friend to two or more of the visits over the course of the study. While at the lab, target children interacted with their parents and peers separately across six tasks (for a list of the tasks, see Appendix A on the Open Science Framework [OSF] page for this project:
During each of the summers prior to entering Grades 9, 10, and 11, participants completed sessions either in their home or in the laboratory (ninth, n = 172; 10th, n = 180; and 11th, n = 178 grades). At the end of these sessions, participants were provided with BlackBerries with paid service plans, configured to capture all incoming and outgoing text-message communication exchanged on the phone. Participants received a new BlackBerry at the conclusion of each visit, and were compensated $50 for their time. Participants used the phones frequently and heavily, exchanging an average of 151.48 texts during each day of coded content (SD = 175.16). Moreover, the overwhelming majority of text-message communication coded for this research was exchanged with their peers (91.84%). Although participants were not prevented from using other devices, we believe that they used these BlackBerries as their primary phones throughout the study given that the average number of messages exchanged per day was slightly higher than self-reported texting rates identified in other studies (
Attrition analyses revealed that 36.9% of participants from the laboratory visit in fourth grade (Time 1) did not have data for the digital communication variables in the 11th grade (Time 7). Although participants’ attrition status was unrelated to their gender and their scores on the digital communication variables, of the 20 tests that investigated links between attrition and warmth, six emerged as statistically significant. Further, the two more strongly powered tests of these six effects suggest that participants who remained in the study from Times 1 to 7 expressed and received less warmth from their friends (though these differences were relatively small; d′s = −.30 and −.33). In sum, there is not much evidence that attrition status was systematically related to the study variables (see Appendix B on the OSF page for this project for more details).
Coding for the behaviors described below was performed by teams of graduate and undergraduate research assistants in the last author’s (MKU) laboratory (32 assistants for warmth and 24 assistants for digital communication). Before coders could provide ratings, they were required to complete weeks-long training (10 weeks for warmth and 8 weeks for digital communication) that involved reviewing the corresponding coding manual and coding practice segments or transcripts until reliability was achieved. Although most segments (80%) were coded by one rater, 20% of transcripts were double coded to assess interrater reliability; given the smaller sample size available to compute interrater reliability, all estimates of interrater reliability that we report below were computed using the entire sample (i.e., the sample includes data from target children who brought different parents to the study across waves).
Observed warmth in middle childhood
Trained coders rated both the target child and her/his interaction partner on warmth for each task at each visit. Coders rated the prominence of positivity/negativity in participants’ communication using a 7-point scale (1 = completely positive, 2 = very positive, 3 = mostly positive, 4 = moderate, 5 = mostly negative, 6 = very negative, 7 = completely negative). They were instructed to consider communication that conveyed friendliness, pleasantness, and kindness as positive, and that which conveyed quarrelsomeness, criticalness, and unresponsiveness as negative. These two forms of communication seem to align closely with items from the “warm-agreeable” (e.g., soft-hearted, accommodating, and kind) and “cold-hearted” (e.g., cruel, unsympathetic, and cold-hearted) subscales from the Interpersonal Adjectives Scales-Revised (
Interrater reliability was acceptable across the six tasks at each wave (target children-to-parents: α ranged from .70 to .89, Median = .83; target children-to-friends: α ranged from .85 to .94, Median = .92; parents-to-target children: α ranged from .72 to .91, Median = .84; friends-to-target children: α ranged from .88 to .93, Median = .92). Each task showed low-to-moderate consistency across all four visits (target children-to-parents: α ranged from .45 to .61, Median = .54); target children-to-friends: α ranged from .13 to .33, Median = .24); parents-to-target children: α ranged from .52 to .71, Median = .62); friends-to-target children: α ranged from .18 to .37, Median = .21). Because expressions of warmth were very consistent for participants across tasks (target children-to-parents: α ranged from .84 to .91, Median = .88; target children-to-friends: α ranged from .87 to .93, Median = .90; parents-to-target children: α ranged from .85 to .91, Median = .87; friends-to-target children: α ranged from .87 to .92, Median = .91), we computed averages for warmth across the tasks and used these composites for the analyses.
Digital communication in early adolescence
Daily transcripts from 2-day samples of the target children’s text-message communication in the Fall and Spring semesters of ninth, 10th, and 11th grades were selected for coding. To ensure that sufficient levels of social interaction would be observed, we initially sampled text-message communication from the target children on days near the homecoming football game and Valentine’s Day for the Fall and Spring semesters, respectively. If we could not find text-message communication for participants near these days, the search parameters were expanded until content was found. This resulted in up to 4 days per year, for a total of 12 possible days of coded text content (M = 9.2 days, SD = 2.92 days, range = 1–12 days). Participants who did not have transcripts during a given day, or sent fewer than 10 text messages within the day, were not rated on the scales described below.
Coding focused on messages sent by the participant, but received messages were used for additional context. Transcripts were coded for: positive affect (i.e., cheerful and caring communication; interrater reliability for each day of messages ranged from α = .46 to .79; Median = .68); negative affect (i.e., cold and quarrelsome behaviors; interrater reliability ranged from α = .32 to .85; Median = .63); social aggression (i.e., behaviors expressed to damage another person’s social relationships; interrater reliability ranged from α = .36 to .83; Median = .72); urgency/demandingness (i.e., behaviors indicating the requirement of immediate feedback; interrater reliability ranged from α = .42 to .92; Median = .71); and duplicity (i.e., deceptive behaviors; interrater reliability ranged from α = .59 to .92; Median = .81).
Prior to conducting these analyses, we used the Monte Carlo simulation capabilities of Mplus Version 6.11 (
As
We used structural equation modeling with maximum likelihood estimation within Mplus 7.4 to fit the cross-sectional reciprocal OWM model with distinguishable members to observed warmth at each of the four time points in middle childhood.
As can be seen, there was little evidence that target children’s experiences with warmth when interacting with their parents and peers were driven by their dispositional tendencies to express or elicit warmth. Instead, it appears that observed warmth was primarily relationship-specific; put another way, the amount of warmth expressed within the parent–child and friend–child pairings had more to do with the unique relationships the target children had with their partners in these observed interactions than their general tendencies to provide or receive warmth. In addition, the dyadic reciprocity correlation coefficients suggest that these relationship-specific expressions of warmth within the parent–child and friend–child interactions were strongly reciprocated. To evaluate whether the dyadic reciprocity correlations significantly differed between friends and parents, we imposed equality constraints on the parameters and performed chi-square difference tests. These findings revealed that the reciprocal exchange of warmth was stronger in the friend–child relationships than the parent–child relationships in the sixth, Δχ
Longitudinal OWM model of warmth
Given our interest in understanding how general qualities of warmth in middle childhood relate to early adolescent digital communication, we sought to construct a longitudinal OWM model that specified the time-specific OWM parameters as indicators of general OWM parameters (see
Because target children typically brought different friends to the study at each wave, indices of friend–child dyadic reciprocity across time were not strongly related; consequently, instead of treating time-specific versions of this variable as indicators of a broader dispositional variable, we freely estimated correlations between the time-specific indices of friend–child dyadic reciprocity across waves. Last, to account for stability in the directed relationship effects, we treated time-specific versions of the relationship effects as indicators of broader dispositional variables (e.g., the stable target child-to-parent relationship effect was indicated by the time-specific versions of this variable at the fourth, fifth, sixth, and seventh grades; note that stable relationship effects are omitted in
We used insights from the cross-sectional OWM analyses to build up the longitudinal OWM model (e.g., fixing the partner effect variances for Grades 6 and 7 to 0). To be consistent with future analyses using skewed outcomes (e.g., digital social aggression), we used robust maximum likelihood (MLR) estimation for this and all subsequent analyses. The initial model did not run. We decided to fix all small and nonsignificant variances that were being estimated as negative in the current model to 0 (namely the time-specific actor effect for the sixth grade and the stable friend-to-target child relationship effect). This modified model ran successfully and demonstrated excellent fit, χ
Regressing digital communication on OWM components
We examined several features of digital communication across early adolescence (i.e., positive affect, negative affect, social aggression, urgency/demandingness, and duplicity). All features were coded for ninth, 10th, and 11th grade, except for social aggression, which was only coded in 10th and 11th grade.
We next evaluated whether experiences with parents and peers had differential effects on the digital outcomes by imposing equality constraints on all of the paths in
Simplified longitudinal analyses
One of the benefits of the longitudinal analyses presented above is that they provide insight into the general relations between reciprocal exchanges of warmth in parent–child and friend–child interactions in middle childhood and different features of digital communication in adolescence. That being said, we acknowledge that our sample size may not be ideal for estimating a model of this complexity. To ensure that our results were not simply an artifact of this more complex longitudinal latent variable model, we specified additional simplified longitudinal models that used the dyadic reciprocity variables from the cross-sectional OWM models at each time point to predict more simplified forms of each of the latent variables for digital communication (for more details, see Appendix E on the OSF project page). With the exception of failing to find evidence that the effects of dyadic reciprocity on urgency/demandingness significantly differed for parent–child and friend–child dyads, the results from these simplified longitudinal analyses showed a similar substantive pattern of results and thus bolster our original set of conclusions.
The present research explored whether experiences with warmth in middle childhood with parents and peers are linked to more positive affect, less negative affect, and less disagreeable interactions in text-message communication in adolescence. The results suggest that observed expressions of warmth in middle childhood are primarily driven by unique features of the parent–child and friend–child relationships. Further, consistent with co-construction theory and the mechanism of socialization, greater exchanges of warmth within these relationships predicted lower levels of negative affect and duplicity within digital communication.
Warmth, constituting one of the two fundamental axes in the interpersonal circumplex (
Research investigating the test–retest reliability of the FFM domains and facets found that the facet of warmth displayed one of the highest test–retest reliability coefficients (
This discrepancy may be partially attributed to differences in the design. Whereas past dyadic research has generally used round-robin SRM designs with families to draw their conclusions, the current research used an OWM design with parents and peers. It could be that family members are more likely to be treated in a similar manner (e.g., each person representing a communal situation;
Another potential reason that significant actor and partner effect variances were not found in the present research is that the number of partners was only two. This small number of partners makes it more difficult to detect systematic consistency (see
This study suggests that observed expressions of warmth in middle childhood between children and their parents and peers are primarily relationship-specific. Indeed, rather than being driven by dispositional features of the target child, expressions of warmth were primarily a function of the unique interpersonal situations encountered in the parent–child and friend–child relationships. This evidence regarding relatively large relationship effect variances is consistent with work by
Relevant to this, the present research also showed that warmth is strongly reciprocated within the parent–child and friend–child relationships. This is consistent with the interpersonal theory principle of complementarity (
Given past research illuminating potential differences in horizontal versus vertical relationships (e.g.,
Co-construction theory posits that, “. . . users . . . [create] their [digital] contexts in conjunction with other users, thus influencing and being influenced by the very online culture that they are helping to create” (
In particular, the results indicate that reciprocal exchanges of warmth within parent–child and friend–child relationships predict less negative affect and duplicity. These findings corroborate research on offline behavior showing that increased expressions of warmth are linked to decreased negative affect (
We also found that reciprocal exchanges of warmth within the parent–child relationship had unique implications for children’s observed urgency/demandingness. Relevant to this, greater parental warmth predicted adolescents’ increased levels of effortful control 2 years later (
In contrast to previous theoretical (cf.
Our results also shed some light on the plausibility of behavioral continuity and parental and peer socialization as mechanisms linking offline behavior to online behavior longitudinally. Simply put, the behavioral continuity mechanism did not receive much support. Because the results of the OWM analyses indicated that observed expressions of warmth did not have a strong dispositional basis, behavioral continuity could not constitute a tenable mechanism given that it presupposes a certain degree of consistency across interaction partners that is carried forward across time. As noted previously, however, it is possible that the current OWM design prevented us from detecting significant actor effect variance. Future research with round-robin SRM designs will be needed to determine whether behavioral continuity helps to explain the transmission of warmth in offline relationships to online relationships.
On the other hand, the OWM analyses indicated that observed expressions of warmth have a strong relational basis. The results further suggest that expressions of warmth were reinforced within these relationships and thus that parental and peer socialization constituted plausible mechanisms for the transmission of warmth. When we investigated linkages, we found that experiences with warmth within these relationships related to decreased negative affect and duplicity within text-message communication. During middle childhood, people further develop their relational schemas (
The present research had a number of strengths. Because we had observational measures of warmth and digital communication, we were able to eliminate shared-method variance as a plausible explanation for our results. Moreover, we were able to observe warmth in two different key relationships—parent–child and friend–child—both of which have clear implications for later development (e.g.,
Our research also had several limitations. To begin, our operationalization of warmth combined features of both warmth from the interpersonal circumplex and the agreeableness dimension of the FFM. As such, higher levels of warmth reflected both more nurturing and agreeable behavior, and lower levels reflected both colder and more quarrelsome behavior. However, researchers have argued that the opposite of warmth may be better construed as aloofness or indifference rather than quarrelsomeness or hostility (e.g.,
In addition, our use of a nonexperimental panel design prevents us from being able to make causal inferences. Although we were able to demonstrate prospective relations between the variables, future research will be needed to evaluate whether reciprocating warmth in key relationships actually reduces the degree to which individuals engage in quarrelsome modes of digital communication. Another limitation is that we did not actually assess warmth in digital communication, which would have permitted us to directly evaluate co-construction theory.
Furthermore, by using the OWM design, we could not disentangle all possible sources of variance. Although nonindependence in the “warm” behaviors is modeled in the analyses via the OWM, it does not necessarily account for the fact that the entire network may be similar in terms of the behavior. To our minds, this is what the “group mean” effect is supposed to capture. Unlike the SRM for a four-person group, however, there are not enough data to estimate all relevant parameters for the SRM; in such situations, it is common to omit the group effect variance (
Given the rising availability of online IM applications such as Snapchat and Facebook messenger, it is reasonable to wonder whether adolescents and young adults continue to use text messaging as frequently (see
Notwithstanding these limitations, this research represents the first attempt to link observational qualities of parent–child and peer–child relationships in middle childhood to the actual content of future text-message communication. Using the OWM design, we found that observed expressions of warmth in middle childhood were primarily relationship-specific. In addition, expressions of warmth within the parent–child and friend–child relationships were linked to less quarrelsome modes of digital communication. Taken together, these findings suggest that children make unique adjustments to their parents and friends in terms of warmth, and these unique adjustments are related to how they use text-message communication.
