Introduction We examined sexual harassment, alongside other forms of peer victimization, as correlates of self-worth, depression, and anxiety (emotional adjustment). In addition, we investigated joint moderating effects of gender and age in the relationship between sexual harassment and emotional adjustment. Methods Participants were 277 high school and 492 university students (12–24 years, 60% female) residing in Australia. All completed a survey to report sexual harassment experiences, as well as in-person and online/social media appearance-related peer victimization, global self-worth, and social anxiety and depressive symptoms. Results Age was positively associated with sexual harassment, as well as with general and social media victimization; males and females did not differ. Participants who reported more sexual harassment reported poorer adjustment, but only the association with depressive symptoms remained significant after controlling for other forms of peer victimization. When gender and age were tested as moderators, the positive association between sexual harassment and depression was significant for all groups but younger males and there was a positive association between harassment and anxiety among only younger females and older males. Conclusion Sexual harassment was commonly reported, but rather weakly and intermittently associated with emotional health, after controlling for appearance-related peer victimization. Future research should examine when and why youth seem fairly resilient to negative emotional effects that could follow sexual harassment. It is possible that messages about the cause of sexual harassment are being heard and this aids youth to avoid self-blame and emotional maladjustment.

Physical dating aggression is a prevalent and costly public health concern. A theoretical moderator model of substance use and dating aggression posits that associations between them are moderated by relational risk factors. To test these theoretical expectations, the current study examined seven waves of longitudinal data on a community-based sample of 100 male and 100 female participants in a Western U.S. city (M age Wave 1 = 15.83; 69.5% White non-Hispanic, 12.5% Hispanic, 11.5% African Americans, & 12.5% Hispanics). Multilevel models examined how links between substance use and dating aggression varied by relational risk and how these patterns changed developmentally. Main effects of relational risk and substance use emerged, particularly in adolescence. In young adulthood significant three-way interactions emerged such that substance use was more strongly associated with physical aggression when conflict and jealousy were higher. Thus, relational risk factors are integral to models of dating aggression, but their role changes developmentally.

The present study explored how romantic relationship qualities develop with age and relationship length. Eight waves of data on romantic relationships were collected over 10.5 years during adolescence and early adulthood from a community-based sample in a Western U.S. city (100 males, 100 females; M age Wave 1 = 15.83). Measures of support, negative interactions, control, and jealousy were derived from interviews and questionnaire measures. Using multilevel modeling, main effects of age were found for jealousy, and main effects of relationship length were found for each quality. However, main effects were qualified by significant age by length interactions for each and every relationship quality. Short relationships increased in support with age. In comparison, long-term adolescent relationships were notable in that they were both supportive and turbulent, with elevated levels of support, negative interactions, control, and jealousy. With age, long-term relationships continued to have high levels of support, but decreased in negative interactions, control, and jealousy. Present findings highlight how the interplay between age and relationship length is key for understanding the development of romantic relationships. (PsycINFO Database Record

Traditionally, studies of romantic relationship dissolution in emerging adulthood have only examined predictors of relationship dissolution within the next few months to a year. The present study explored contextual-, relationship-, and individual-level predictors of breakups over a total of 6 years, both in the short-term (1 year after data collection) and in the long-term (an additional 5 years). Data were collected from a community-based sample (100 males, 100 females, ages 18–24). With regard, to dissolution in the short-term, lower levels of relationship support and romantic appeal predicted that the relationship dissolved sooner. For relationships that had not dissolved within the next year, these same predictors, as well as life stress, negative interactions, externalizing symptoms, substance use, and age, predicted time to dissolution over the following 5 years. Findings highlight the importance of simultaneously examining contextual, relationship, and individual levels of short- and long-term predictors to better understand relationship dissolution.

The sex-positive framework of sexual development hypothesizes that healthy sexual experiences can be developmentally appropriate and rewarding for adolescents despite the risks involved. Research has not examined whether risky behaviors and rewarding cognitions actually change with sexual debut at a normative or late age. This study measured the longitudinal impact of sexual debut using 7 waves of data from 88 male and 86 female adolescents from a western U.S. city who were in the 10th grade at the study's onset. We used piecewise growth curve analyses to compare behaviors and cognitions before and after first sexual intercourse for those whose debut was at a normative or late age. These analyses revealed that sexual debut was related to rewards, including increases in romantic appeal and sexual satisfaction. In addition, internalizing symptoms declined over time after sexual debut, and substance use grew at a slower rate after sexual debut. We also examined whether differences existed among those whose debut was at an early, normative, or late age. Linear growth curve analyses revealed early sexual debut was related to risks, such as greater substance use, more internalizing and externalizing symptoms, and lower global self-worth. Rewards associated with an early debut included greater romantic appeal, dating satisfaction (males only), and sexual satisfaction (males only). Although there are some inherent risks with sexual activity, the results suggest that sexual debut at a normative or late age is also associated with a decrease in some risks and an increase in rewards.

Violence within romantic relationships is a significant public health concern. Previous research largely explores partner violence at one or two time points, and often examines a limited set of risk factors. The present study explored both individual and relationship-level risk factors and their associations with physical victimization and perpetration across more than 10 years using a community sample of 200 participants (50 % female; M age Wave 1 = 15.8). Additionally, we explored the effects of previous partner violence on the likelihood of future partner violence. Survival analysis indicated that externalizing symptoms and negative interactions (e.g., relationship conflict) were associated with both perpetration and victimization. Reporting an experience of partner violence did not significantly alter an individual's risk of future partner violence. Overall, men were significantly more likely to report victimization; perpetration rates did not vary by gender. The results highlight the importance of examining multiple levels of risk.

The present study assessed a developmental task theory of romantic relationships by examining associations between romantic relationship qualities and adjustment across 9 years using a community-based sample of 100 male and 100 female participants (Mage Wave 1 = 15.83) in a Western U.S. city. Using multilevel modeling, the study examined the moderating effect of age on links between romantic relationship qualities and adjustment. Consistent with developmental task theory, high romantic quality was more negatively associated with internalizing symptoms and dating satisfaction during young adulthood than adolescence. Romantic relationship qualities were also associated with externalizing symptoms and substance use, but the degree of association was consistent across ages. The findings underscore the significance of romantic relationship qualities across development.

Dating aggression has been identified as a priority public health concern. Although alcohol use is a known robust risk factor for dating aggression involvement, such usage is neither necessary nor sufficient for dating aggression involvement. As such, a growing topic of interest is a better understanding of when, and for whom, alcohol use increases risk. A theoretical moderator model posits that associations between alcohol use and dating aggression involvement vary depending on both background (e.g., psychopathology) and situational (e.g., relationship characteristics) risk factors. Alcohol use is thought to be more strongly associated with dating aggression in the context of these other risk factors. Using an intensive longitudinal design, we collected six waves of data spanning six months from 120 participants (60 females; M age W1 = 22.44). Alcohol use and relationship risk were both associated with increases in dating aggression involvement. Consistent with a moderator model, interactions emerged between alcohol use and relationship risk for subsequent dating aggression involvement. The findings underscore the importance of alcohol use and relationship risk for the development of intervention and prevention programs.

Little is known about the effect of sexual coercion on romantic relationship quality and dating experiences. The current study aimed to address this dearth in the literature and test the hypothesis that sexual coercion has a negative impact on victims' subsequent romantic experiences. Using a sample of 94 youth (44 males and 50 females), the current study addressed the impact of sexual coercion on romantic relationship quality and dating experiences. Tracking youth for 8.5 years (M age at Wave 1 = 15.10 years, SD = .49), the current study used piecewise growth curve modeling to account for shifts in the intercept and slope of romantic experiences following sexual coercion. Negative interactions immediately increased following coercion and continued to have an accelerated rate of growth (i.e., a slope change). Jealousy in romantic relationships increased in slope. Serious dating decelerated following the coercive incident. Results were largely consistent across gender and severity of the coercive incident. Contrary to hypotheses, relational support, relationship satisfaction, and casual dating did not significantly change following sexual coercion. Consistent with hypotheses, sexual coercion had a negative impact on romantic experiences. These findings have clinical implications for both prevention and intervention around sexual violence. In addition, the consistency of findings across gender and severity suggests that increased focus should be directed toward both male sexual coercion and less severe sexual coercion.

This study examined how representations of parent-child relationships, friendships, and past romantic relationships are related to subsequent romantic representations. Two-hundred 10th graders (100 female; Mage = 15.87 years) from diverse neighborhoods in a Western U.S. city were administered questionnaires and were interviewed to assess avoidant and anxious representations of their relationships with parents, friends, and romantic partners. Participants then completed similar questionnaires and interviews about their romantic representations six more times over the next 7.5 years. Growth curve analyses revealed that representations of relationships with parents, friends, and romantic partners each uniquely predicted subsequent romantic representations across development. Consistent with attachment and behavioral systems theory, representations of romantic relationships are revised by representations and experiences in other relationships.

Few studies have examined the associations of sexual activity with romantic cognitions, particularly longitudinally. We used a multianalytic approach to examine the longitudinal, between-person, and within-person associations between sexual activity and romantic cognitions. We distinguished among sexual activity with four different types of partners—romantic partners, friends, acquaintances, and friends with benefits. An ethnically/racially representative sample of 185 participants (94 males and 91 females) completed questionnaires when they were 2.5, 4, and 5.5 years out of high school. Frequent sexual activity with a romantic partner was associated with positive romantic cognitions, including less avoidant and anxious relational styles, greater romantic life satisfaction, and romantic appeal. Frequent sexual activity with various nonromantic partners was often associated with more negative romantic cognitions, including avoidant styles, lower romantic life satisfaction, and lower romantic appeal. Few longitudinal effects were found. Findings contribute to a developmental task theory concepualization of sexual behavior.

The purpose of the present study was to provide a detailed examination of sexual behavior with different types of partners. A sample of 163 young adults reported on their light nongenital, heavy nongenital, and genital sexual activity with romantic partners, friends, and casual acquaintances. They described their sexual activity with “friends with benefits” as well as with friends in general. Young adults were most likely to engage in sexual behavior with romantic partners, but sexual behavior also often occurred with some type of nonromantic partner. More young adults engaged in some form of sexual behavior with casual acquaintances than with friends with benefits. The frequencies of sexual behavior, however, were greater with friends with benefits than with friends or casual acquaintances. Interview and questionnaire data revealed that friends with benefits were typically friends, but not necessarily. Nonsexual activities were also less common with friends with benefits than other friends. Taken together, the findings illustrate the value of differentiating among different types of nonromantic partners and different levels of sexual behavior.

Research has consistently demonstrated the negative consequences of depression on adolescents' functioning in peer and family relationships, but little work has examined how depressive symptoms affect the quality of adolescents' and emerging adults' romantic relationships. Five waves of data on depressive symptoms, romantic relationship conflict, and use of positive problem solving were collected from 188 boys and girls during middle adolescence to emerging adulthood. Latent growth curve models indicated that having more depressive symptoms when 15 years old was associated with both more increase in relationship conflict and less increase in positive problem solving as compared to adolescents with fewer depressive symptoms. These results suggest that depression in middle adolescence may impair subsequent romantic relationship qualities into late adolescence and emerging adulthood.

The present study examined the hypotheses that more secure representations of attachments to parents are associated with less adolescent substance use over time and that this link is mediated through relationship quality and monitoring. A sample of 200 adolescents (M = 14 to 16years), their mothers, and close friends were assessed over a 2 years. Higher levels of security in attachment styles, but not states of mind, were predictive of higher levels of monitoring and support and lower levels of negative interactions. Higher levels of security in attachment styles had an indirect effect on changes in substance use over time, mediated by maternal monitoring. These findings highlight the roles of representations of attachments, mother-adolescent relationship qualities, and monitoring in the development of adolescent substance use.

This paper describes an alternative version of the Network of Relationships Inventory, which was designed to assess how frequently different relationships were used to fulfill the functions of three behavioral systems: attachment, caregiving, and affiliation. Psychometric and validational evidence is presented including: (a) high internal consistency for all scales and composites; (b) a second order factor structure of support and negative interactions for each relationship; (c) moderately high stability over a one year period; (d) moderate convergence among different reporters; (e) theoretically meaningful differences among different relationships; (f) moderate associations among different relationships; (g) associations with the original Network of Relationships Inventory; and (h) relations with observed interactions with mothers and friends.

This study examined how parent—adolescent relationship qualities and adolescents’ representations of relationships with parents were related to interactions in 200 adolescent—close friend dyads. Adolescents and friends were observed discussing problems during a series of structured tasks. Negative interactions with mothers were significantly related to adolescents’ greater conflict with friends, poorer focus on tasks, and poorer communication skills. Security of working models (as assessed by interview) was significantly associated with qualities of friendship interactions, whereas security of attachment styles (as assessed by questionnaire) was not. More dismissing (versus secure) working models were associated with poorer focus on problem discussions and weaker communication skills with friends, even after accounting for gender differences and current parent—adolescent relationship qualities.

This study used a social exchange framework to examine the features of non-romantic other-sex (OS) friendships compared with same-sex (SS) friendships and romantic relationships. High school seniors (N = 141) completed open-ended interviews about the benefits and costs of having OS friendships, SS friendships, and romantic relationships in general. As expected, perspective taking, learning about the other sex, and meeting the other sex were seen as rewards of OS friendships more often than for SS friendships and romantic relationships. Confusion about the nature of the relationship was seen as a cost of OS friendships more often than of SS friendships and romantic relationships. Intimacy, support, and companionship were mentioned less often as rewards of OS friendships than romantic relationships. Adolescents also completed questionnaires about their own specific relationships of each type. Their OS friendships were perceived as less supportive than their other two relationships; OS friendships were also seen as having fewer negative interactions than romantic relationships. Our findings expand the application of social exchange theory and lend empirical support to prior speculations about OS friendships and their importance in adolescents' social worlds.

Dating aggression is a prevalent and costly public health concern. Using a relational risk framework, this study examined acute and chronic relational risk factors (negative interactions, jealousy, support, & relationship satisfaction) and their effects on physical and psychological dating aggression. The study also examined the interaction between chronic and acute risk, allowing us to assess how changes in acute risk have differing effects depending on whether the individual is typically at higher chronic risk. A sample of 200 youth (100 female) completed seven waves of data, which spanned nine years from middle adolescence to young adulthood (M age at Wave 1 = 15.83). Using hierarchical linear modeling, analyses revealed both acute (within-person) and chronic (between-person) levels in jealousy, negative interactions, and relationship satisfaction, were associated with physical and psychological dating aggression. Significant interactions between chronic and acute risk emerged in predicting physical aggression for negative interactions, jealousy, and relationship satisfaction such that those with higher levels of chronic risk are more vulnerable to increases in acute risk. These interactions between chronic and acute risk indicate that risk is not static, and dating aggression is particularly likely to occur at certain times for youth at high risk for dating aggression. Such periods of increased risk may provide opportunities for interventions to be particularly effective in preventing dating aggression or its consequences. Taken together, these findings provide support for the role of relational risk factors for dating aggression. They also underscore the importance of considering risk dynamically.

Being a victim of sexual aggression from a peer is a common experience among adolescents and poses a significant risk for various forms of psychopathology. Unfortunately, little is known concerning specific interpersonal factors that increase an adolescent’s risk for experiencing sexual aggression. The current study assessed the contribution made by several interpersonal factors both for the first and repeated experience of becoming a victim of sexual aggression from a peer. Data were collected annually from a longitudinal sample of 200 adolescents over a period of 4 years and were analyzed using multiple-spell, discrete-time survival analysis. Approximately 46% of the adolescents reported experiencing some form of sexual aggression by the end of wave 4. Further, 65% of victims reported experiencing a repeat incident of aggression. Females were at higher risk both for initial and repeated victimization, as were adolescents with more sexual experience and higher levels of rejection sensitivity. Results are discussed in terms of implications for future prevention efforts.

This study examined how same–sex peers influence young women's body image and mood. Eighty female undergraduates were randomly assigned to observe one of two different prearranged conversations between confederates. In one conversation condition, one confederate pressured the other to be thin. In the other conversation condition, one confederate provided positive encouragement to the other about her body image. There was no main effect of condition. Instead, social comparison tendency and appearance orientation moderated the effects of pressure to be thin on body image. Females high on these dimensions were particularly vulnerable to peer pressure to be thin. Similar findings were found with respect to positive and negative emotions. The findings contribute to our understanding of how same–sex peers influence young women's body image and mood.

This chapter reviews the current state of the literature on children and adolescents' dyadic peer relationships. Particular emphasis is placed on children and adolescents' same-sex friendships and romantic relationships, but research on other-sex friendships, antipathies, passionate friendships, and sexual relationships are covered as well. The chapter uses a unified relational perspective, which has four key points. First, friendships and romantic relationships need to be studied as relationships. They are dyadic phenomena with a history. Second, children and adolescents' friendships, romantic relationships, and other peer relationships all share common features. They have been studied as separate phenomena and typically by different investigators, but the field would benefit by simultaneously considering all of these types of relationships. Third, any particular relationship is embedded in a network of dyadic relationships. Finally, dyadic peer relationships cannot be understood without incorporating the contexts in which they occur, such as the general peer group, family, and culture. Using this unified relational perspective, the chapter reviews research on the development of dyadic relationships, the role of the self and partner and gender. The chapter then discusses the associations with family relationships, the peer group, media, and the cultural context in which they are embedded. The links between relationships and adjustment are also covered. The chapter also outlines a number of definitional, conceptual, methodological, and analytical issues that need to be addressed in future research, and identifies a number of understudied topics. It concludes by discussing the merits of the unified relational perspective. Keywords: dating; friends; friendships; romantic relationships; social networks

The present study examined how adolescents' and their romantic partners' romantic working models and relational styles were related to their interactions with each other. Sixty-five couples (M age = 18.1 years) were observed interacting. Romantic working models were assessed in interviews about their romantic experiences; romantic styles were assessed by self-report. Data were analyzed using the Actor Partner Interdependence Model. Working models of romantic relationships, especially girls' models, were predictive of their behavior, the partners' behavior, and the dyads' behavior. Fewer links were found between relational styles and observed behavior. The present study extends past work by showing that representations of romantic relationships influence or are influenced by romantic interactions, even as these representations and relationships are just developing.

A two-year longitudinal investigation examined adolescents' (N = 100 girls and 99 boys) perceptions of social support in relationships with mothers, close friends, and romantic partners from Grade 10 (ages 14–16) to Grade 12 (ages 16–18). Adolescents, mothers, and close friends also provided descriptions of the participants' global self-worth and interpersonal competence. Variable-centered and person-centered analyses revealed that perceived social support tends to be similar across relationships and stable over time. Variable-centered analyses indicated that social support in mother-adolescent relationships was uniquely related to adolescent global self-worth; that social support in close friendships was uniquely related to social acceptance, friendship competence, and romantic competence; and that social support in romantic relationships was uniquely related to romantic competence. Person-centered analyses indicated that adolescents who reported high social support in all three relationships had higher self-worth and greater interpersonal competence than those who did not have a romantic relationship and who reported low social support in relationships with mothers and close friends; and that scores for adolescents who had a romantic [End Page 572] relationship but who reported low social support in all three relationships fell in between these two groups. Taken together, variable-centered analyses suggest that different relationships influence different dimensions of competence, but person-centered analyses indicate that a sizable proportion of adolescents have relationships that act in concert with one another.

It is believed that by adulthood, independent attachments to the mother and the father coalesce into a single state of mind with respect to attachment. If true, states of mind with respect to mothers and fathers should be concordant. Fifty-six young adults were administered two versions of the Adult Attachment Interview, each of which asked about their relationship with one parent. State of mind with respect to the father was significantly related to state of mind with respect to the mother, as were attachment styles regarding the two parents. Perceptions of attachment styles were not very related to corresponding states of mind but were related to inferred loving from a parent.

This study examined the links among adolescents' representations of their relationships with parents, friends, and romantic partners. Sixty-eight adolescents were interviewed three times to assess their working models for each of these types of relationships. Working models of friendships were related to working models of relationships with parents and romantic partners. Working models of relationships with parents and romantic partners were inconsistently related. A similar pattern of results was obtained for self-report measures of relational styles for the three types of relationships. Perceived experiences were also related. Specifically, support in relationships with parents tended to be related to support in romantic relationships and friendships, but the latter two were unrelated. On the other hand, self and other controlling behaviors in friendships were related to corresponding behaviors in romantic relationships. Negative interactions in the three types of relationships also tended to be related. Taken together, the findings indicate that the representations of the three types of relationships are distinct, yet related. Discussion focuses on the nature of the links among the three.

The present study examined the development of friendship conceptions from 4 to 7 years of age. Subjects were administered an open-ended interview, a picture recognition task, and a forced-choice rating task in which they identified the most important characteristics of friendship. Common activities, affection, support, and propinquity were all found to be salient aspects of most children's conceptions. Friendship expectations concerning affection and support increased m frequency with age, while references to physical characteristics decreased. In general, parallel findings were found on the 3 measures, although the results were not as strong on the open-ended interview. The findings suggest that children first learn the overt characteristics of the occupants of the role of friend, but as they grow older they place increasing emphasis on affectively based characteristics.

The current study examined young children's use of the presence or absence of extrinsic reward to make inferences about the intrinsic motivation of another person. Previous research indicates that most kindergartners do not use a discounting heuristic, but it was hypothesized that they may have misinterpreted the questions asked. Kindergarten, second, and fourth graders were presented stories about children who were rewarded or not rewarded for performing various activities Two forms of questioning about motivation were compared. When a traditional form was used, kindergartners did not show evidence of a discounting heuristic. When the questions were adjusted to ask more specifically about intrinsic motivation, children at all grade levels appeared to use a discounting heuristic. Results are discussed in terms of the parameters of the attributional effects, the possible mechanisms responsible for the phenomena, and the significance of the findings for other developmental research using self-report techniques.

The present study compared two theories of the association between romantic involvement and adjustment: a social timetable theory and a developmental task theory. We examined seven waves of longitudinal data on a community based sample of 200 participants (Wave 1 mean age = 15 years, 10 months). In each wave, multiple measures of substance use, externalizing symptoms, and internalizing symptoms were gathered, typically from multiple reporters. Multilevel modeling revealed that greater levels of romantic involvement in adolescence were associated with higher levels of substance use and externalizing symptoms but became associated with lower levels in adulthood. Having a romantic partner was associated with greater levels of substance use, externalizing symptoms, and internalizing symptoms in adolescence but was associated with lower levels in young adulthood. The findings were not consistent with a social timetable theory, which predicts that nonnormative involvement is associated with poor adjustment. Instead, the findings are consistent with a developmental task theory, which predicts that precocious romantic involvement undermines development and adaptation, but when romantic involvement becomes a salient developmental task in adulthood, it is associated with positive adjustment. Discussion focuses on the processes that may underlie the changing nature of the association between romantic involvement and adjustment.

The purpose of this study was to determine if a narrative technique based on the Adult Attachment Interview could be used for studying working models of friendships. A Friendship Interview was developed and administered to a sample of 68 high school seniors. Theoretically coherent factors reflecting friendship experiences and working models were obtained. Ratings of dyadic support from friends were related to secure working models, and inversely related to dismissing working models. Ratings of friend controlling-self dependent behavior and self controlling-friend dependent behavior were related to preoccupied working models. Ratings of experiences in friendships were related to self-perceptions of friendships. Working models were related to self-perceptions of relational styles and attachment styles.

Adolescents' peer structures and the quality of their friendships were explored as antecedents of romantic relationships. Longitudinal data were gathered in a sample of 180 high school students over a 3-year period from grade 9 to grade 11. Consistent with Dunphy (1963), small groups of close friends were predictive of other-sex peer networks which were, in turn predictive of the emergence of future romantic relationships. Indirect effects were found for same-sex groups of close friends and same-sex networks. Consistent with Furman and Wehner (1994), the qualitative features of relationships with both friends and romantic partners were predictive of the qualitative features of subsequent romantic experiences. These linkages suggest ways in which peer relationships may support romantic development at this stage of the life cycle.

The articles in this special issue tell a story of adolescence--a remarkably consistent and coherent story. It is a story of the emergence of other-sex relationships of the change from the predominantly same-sex peer networks of preadolescents to the networks of adolescents containing several new forms of other-sex relationships. These papers highlight the richness of these relationships and the individual dyadic and contextual factors that influence and are influenced by the emergence of these relationships in the adolescent social arena. It is a story that is only now being told by social scientists and one to which these papers contribute substantially. In our commentary we summarize our rendition of this story highlight the key themes in these papers and point out the chapters that remain to be written in this story of adolescent other-sex relationships.

The purposes of this study were to describe the nature of sibling relationships in young adulthood and to examine correlates of individual differences in adults' sibling relationships. A new measure, the Adult Sibling Relationship Questionnaire (ASRQ; R. P. Lanthier & C. Stocker, 1992), was developed with 2 samples (N = 383). The factor structure of the ASRQ indicated that sibling relationships in early adulthood were characterized by 3 independent dimensions: warmth, conflict, and rivalry. Individual differences in adults' warmth, conflict, and rivalry with siblings were somewhat associated with family structure variables and were linked to the amount of contact between siblings and to siblings' mental health.

Intimate partner violence often begins during the courtship stage of romantic relationships. Although some relationships dissolve as a result of aggression, other relationships remain intact, increasing the risk for escalated violence. The present study identified factors predictive of individual differences in emerging adults’ commitment to physically aggressive or sexually coercive dating relationships. Specifically, Rusbult’s Investment Model of romantic relationships (e.g., investment, satisfaction, quality of alternatives, and commitment) was applied to a longitudinal sample of 148 young adult women who reported experiencing aggression or coercion from their current partners. To further explain commitment within aggressive or coercive dating relationships, rejection sensitivity and anxious and avoidant romantic relational styles were included as predictors of the Investment Model variables. A more avoidant romantic style indirectly predicted commitment through relationship satisfaction and investment. Both commitment and rejection sensitivity significantly predicted continuing an aggressive or coercive relationship 6 months later. The present study improves our understanding of the processes involved in relationship commitment. Continuing to understand these processes will inform interventions that seek to help women who have decided to end aggressive or coercive dating relationships.

When adolescents begin using substances, negative consequences are not always directly proportional to the amount used; heavy users may have few consequences whereas light users may have numerous consequences. This study examined how parental monitoring knowledge and parent-child relationship quality may serve as buffers against negative consequences when adolescents use substances. Self-report questionnaires were administered to a community sample of 200 healthy adolescents and their parents at two time points, one year apart. Results suggest that both parental monitoring knowledge and parent-child relationship quality serve as buffers against negative consequences of substance use – but only when adolescents report high levels of monitoring knowledge or strong parent-child relationship quality. Results suggests adolescent perceived parental monitoring knowledge and parent-child relationship quality each act independently to buffer adolescents against negative consequences of substance use over a one-year period.

The present study examined factors associated with harmony in adolescent girls' relationships with their mothers and their best friends. A framework was proposed in which relationship harmony was expected to be related to individual characteristics of each partner and the match between the individual characteristics of each partner. 60 adolescent girls, their mothers, and their best friends participated in self-report and observational tasks. Harmonious mother-daughter partners (vs. disharmonious ones) had more similar needs, felt their needs were better met, perceived their partners as more socially skilled, and had more similar interests. Harmonious friends (vs. disharmonious ones) had more similar needs, and target adolescents perceived partners to be more socially skilled and better at meeting their needs. Observational ratings of attunement, positive affect, and power negotiation were greater in harmonious relationships with both mothers and friends. Discussion focuses on the value of a common framework for studying different relationships.

The present study examined whether positive or negative links occur between psychosocial adjustment and sexual activity with four types of partners—romantic partners, friends, acquaintances, and friends with benefits. We examined longitudinal associations and concurrent between-person and within-person associations. A representative sample of 185 participants (93 males, 92 females), their friends, and mothers completed questionnaires when the participants were 2.5, 4, and 5.5 years out of high school. Regardless of the type of partner, more frequent sexual activity relative to the sexual activity of other young adults was associated with more substance use and risky sexual behavior (i.e., between-person effects). Similarly, for all types of nonromantic partners, more frequrent sexual activity relative to one’s own typical sexual activity was associated with more substance use and risky sexual behavior (i.e., within-person effects). Differences in frequency of sexual activity with friends and acquaintances were associated with greater internalizing and externalizing symptoms as well as lower self-esteem. Follow-up analyses revealed the associations were particularly strong for friends with benefits. Women’s sexual activity frequency with a nonromantic partner was more commonly associated with poorer psychosocial adjustment than such activity by men. More frequent sexual activity with a romantic partner was associated with higher self-esteem and lower internalizing symptoms. Few long-term effects were found for any type of sexual activity. The findings underscore the importance of examining relationship context and illustrate the value of using multiple analytic strategies for identifying the precise nature of associations.

Investigators have identified a number of factors that increase the risk for experiencing sexual coercion, but as yet little is known about how sexual coercion in turn affects these risk factors. Using a sample of 110 adolescents, the current study examined the hypothesis that, after an incident of sexual coercion, adolescents would exhibit increases in several behaviors known to increase risk for victimization. As predicted, after experiencing sexual coercion, adolescents reported increased externalizing symptoms, more frequent sexual intercourse and a greater total number of intercourse partners. Finally, alcohol use, drug use, and problems related to substance use increased. These findings suggest the presence of a feedback loop, in which the experience of sexual coercion leads to an intensification of the factors that initially contributed risk for coercion.

The current study examined longitudinal associations between friend's substance use, friendship quality, parent-adolescent relationship quality and subsequent substance use. Participants were 166 adolescents, their parents and their close same-sex friends. Measures of relationship characteristics in the 10(th) grade were used to predict concurrent substance use and changes in substance use over a one-year period. The most consistent predictor of the use of different substances and changes in substance use over time was the friend's substance using behavior. Negative interactions with a friend were related only to tobacco use, and friendship support neither contributed to nor protected against substance use. Mother-adolescent relationship support was associated with lower levels of concurrent substance use, as well as lower levels of hard drug use over time. Findings highlight the need to examine parents and peers simultaneously and the importance of parental relationships and peer behavior on adolescent substance use. Limitations and future directions are discussed.

One of Bowlby’s (1969) important ideas was that individuals develop mental representations of their relationships with others. Such representations guide their behavior with others and serve as a basis for predicting and interpreting others’ behavior. The purpose of the present study was to examine how such representations of romantic relationships are related to genital, light and heavy nongenital, and risky sexual behavior in adolescence. Based on behavioral systems theory (Furman & Wehner, 1994), we conceptualized such representations of romantic relationships as expectations regarding intimacy and closeness with respect to the attachment, affiliative, caregiving and sexual/reproductive systems in romantic relationships (Furman & Simon, 1999). This conceptualization resembles attachment theorists’ conceptualization of attachment-related mental representations (see Mikulincer & Shaver, 2008), but incorporates representations regarding affiliation, caretaking, and sexuality, as well as attachment. Representations of these other behavioral systems were incorporated as each of the different behavioral systems are central in romantic relationships (Furman & Wehner, 1994; Hazan & Shaver, 1988); thus, we anticipated that romantic representations would incorporate experiences and interactions relevant to all behavioral systems and not solely the attachment system. Similar to attachment theorists, we characterize individual differences in mental representations in terms of the continuous dimensions of avoidance and anxiety with regard to romantic relationships. Those who are avoidant in romantic relationships are not comfortable with intimacy and prefer self-reliance; thus, they are unlikely to turn to their partners, don’t like being turned to, are not very invested in a relationship, and see sexuality as an opportunity for self-gratification. Those who are anxious regarding romantic relationships may worry about rejection and be overly dependent on others for support and esteem; they may find it difficult to feel comforted by a partner when distressed, be overly concerned about a partner's sexual satisfaction or problems (i.e., compulsive caretaking) and overly invest in relationships in a self-sacrificing manner. As can be seen, the present behavioral systems theory conceptualization of mental representations is relatively similar to attachment theory’s conceptualizations of such representations. In fact, the differences in conceptualization are not particularly pertinent to the present study. We believe that the two theories would use similar theoretical arguments and make the same predictions regarding the links with sexual behavior that are examined here. Moreover, attachment researchers conducted most of the relevant research examining the links between representations and sexual behavior in adults.

Currently, little attention is paid to theory in the field of adolescent friendship. Using the chapters in this volume as background, the author delineates a series of questions that must be addressed by theorists and empirical investigators alike.

Using a sample of 199 adolescents, the present study examined Furman and Wehner’s (1999) hypothesis that the predictors of the degree of romantic involvement and the predictors of romantic relationship cognitions and qualities differ. As hypothesized, physical appearance and friends’ normative romantic involvement were related to the degree of casual and serious romantic involvement, whereas relational styles regarding friends and parents were unrelated in almost all cases. On the other hand, relational styles regarding friends and parents were related to supportive and negative romantic interactions and romantic styles,. In contrast, physical appearance and friends’ normative romantic involvement were generally unrelated to interactions and romantic styles. Physical appearance was also related to romantic appeal and satisfaction.

This project examined whether interpersonal pressure to be muscular predicted late adolescents’ pursuit of muscularity. Participants were 199 adolescents (16—19 years), mothers ( n = 175), and friends ( n = 159), assessed at two annual times. Pressure to be muscular was assessed with adolescents’, mothers’, and friends’ reports of their relationships. Adolescents reported pressure from fathers and romantic partners, appearance satisfaction, disordered eating, and pursuit of muscularity. Adolescents’, mothers’, and friends’ reports of pressure related to pursuit of muscularity at both times. Adolescents’ perceptions and mothers’ reports prospectively predicted pursuit of muscularity. Findings highlight the relevance of relationships to pursuit of muscularity in late adolescents.

This study examined how current parent-adolescent relationship qualities and adolescents’ representations of relationships with parents were related to friendship interactions in 200 adolescent-close friend dyads. Adolescents and friends were observed discussing problems during a series of structured tasks. Negative interactions with mothers were significantly related to adolescents’ greater conflict with friends, poorer focus on tasks, and poorer communication skills. Security of working models (as assessed by interview) was significantly associated with qualities of friendship interactions, whereas security of attachment styles (as assessed by questionnaire) was not. More dismissing (vs. secure) working models were associated with poorer focus on problem discussions and weaker communication skills with friends, even after accounting for gender differences and current parent-adolescent relationship qualities. We discuss possible mechanisms for the observed links between dimensions of parent-adolescent relationships and friendships. We also consider methodological and conceptual differences between working model and style measures of attachment representations.
