Although borderline personality is characterized by a variety of interpersonal antecedents and consequences, interpersonal theory has yet to develop an adequate model of the disorder. It was hypothesized that considerations of non-interpersonal features that influence interpersonal behavior can inform the description of the interpersonal process associated with borderline personality. Specifically, it was proposed that borderline personality is not adequately conceptualized as characterized by rigid and extreme traits. Instead identity diffusion, or under-developed personality organization, characterizes the disorder, as do notable problems with perception and behavioral impulsivity. Three samples of dyads interacting in a collaborative task were compared using structural equation models of their traits and situational behavior from the perspectives of multiple raters. Two samples included dyads without a borderline interactant and one dyad had one person with and another without borderline personality features. It was hypothesized that dyads including borderline participants would manifest behavior that deviates from normative interpersonal processes. Results were consistent with hypotheses in suggesting that dyads without an individual who has borderline characteristics demonstrate very similar interpersonal patterns, whereas dyads with a borderline interactant deviate from normative interpersonal process. Specifically, borderline individuals appear to be hyper-perceptive of others’ efforts to control (dominate or submit to) them. With regard to affiliation (warmth vs. coldness), borderline individuals appear to have very different perceptions of their own interpersonal style than do individuals who know them, and unlike nonborderline individuals, these styles exert minimal influence on their behavior in interpersonal situations. These results suggest practical implications that vary across interpersonal dimensions. Data imply that clinicians should take seriously suggestions by borderline patients that they feel controlled. With regard to affiliation, data are consistent with the theory of identity diffusion in suggesting that borderline personality features are associated with a lack of stable interpersonal traits that influence behavior across situations, and the development of such a style is an important therapeutic target.

It is widely accepted in our society that people’s paralinguistic (i.e., non-semantic characteristics of the voice) and nonverbal (i.e., posture, gestures, and facial expressions) behaviours play an important role in conveying information about their personality traits. Two particularly relevant traits include one’s preferred levels of dominance and affiliation, which are the two major axes of the interpersonal circumplex. The current study investigates how dominance and affiliation are conveyed through paralinguistic and nonverbal behaviour using a lens model framework. Two major issues addressed by this framework include: 1) How do observers make inferences about people’s dominance and affiliation using paralinguistic and nonverbal behaviours and 2) How do people’s trait dominance and affiliation relate to these behavioural cues? To examine these two questions, we collected data from 114 opposite-sex dyads who worked together to complete a relatively unstructured collaborative task. The videotaped interactions were coded for specific paralinguistic (e.g., pitch, volume, resonance) and nonverbal (e.g., hand gestures, trunk posture, facial expressions) behaviours, in addition to coding more global displays of dominance and affiliation. Participants also completed several measures of trait dominance and affiliation, which tapped both their relatively conscious (i.e., explicit) and their relatively unconscious (i.e., implicit) levels of these traits. Our findings suggest that observers used mainly paralinguistic behaviour to infer dominance and mainly nonverbal behaviour to infer affiliation. In comparison to observers’ perceptions, there were fewer significant relations between individuals’ self-reported trait dominance and affiliation and the nonverbal and paralinguistic behaviours they expressed during the interaction, suggesting that people may have limited conscious awareness of how these behaviours convey information about their trait dominance and affiliation. In line with this idea, several behaviours showed relations to implicit measures of trait dominance and affiliation. We also conducted factor analyses of the measured paralinguistic and nonverbal behaviours, to examine whether or not these behaviours might co-occur as subsets or factors. We found that paralinguistic and nonverbal behaviours can be captured by overarching factors which relate meaningfully to measures of dominance and affiliation. Finally, we demonstrated that dyad members’ paralinguistic and nonverbal behaviours become interdependent as they interact with one another.

Sleep problems are robust suicide risk correlates. According to the interpersonal theory of suicide, thwarted belongingness (TB) and perceived burdensomeness (PB) may explain the link between sleep problems and suicide risk. This study examined these relationships among 331 community-dwelling adults identifying as sexual and/or gender minorities. Self-report measures of sleep problems, TB, PB, suicide risk, and anxiety were completed. Bootstrap mediation analyses were conducted to test TB and PB as interacting, individual, and parallel explanatory factors linking sleep problems and suicide risk. Sleep problems were associated with greater TB, PB, and suicide risk. TB and PB, in parallel and individually, accounted for the relationship between sleep problems and suicide risk, beyond age and anxiety. In contrast to the interpersonal theory, the indirect effect of PB was stronger at lower levels of TB and the indirect effect of TB was stronger at lower levels of PB. Exploratory analyses indicated significant differences between sexual minorities, gender minorities, and individuals identifying as both sexual and gender minorities: the indirect effect of sleep problems on suicide risk through PB was descriptively strongest among sexual minorities, and the indirect effect through TB was descriptively stronger among gender minorities and individuals identifying with both minority groups. Findings suggest that intervening upon TB and PB may thwart the trajectory from sleep problems to suicide risk among sexual and gender minorities. Further work is needed to determine whether suicide risk pathways differ across minority groups.

abstract: This study examined the relationship of client pretreatment interpersonal problems (measured by the Inventory of Interpersonal Problems) to the therapeutic alliance (as measured early in treatment by a self report version of the Working Alliance Inventory‐ Short) using multilevel modeling to account for client and counselor variables. Specifically, the correlations of dominance, hostility and cold/distance interpersonal problems with the initial working alliance were investigated. Participants consisted of 144 clients and 44 graduate student counselors at the Counselor Training Center at Arizona State University. The intraclass value of .23 indicated there is a sizable effect, with counselor differences accounting for 23% of the variance in client alliance ratings, supporting the use of multilevel modeling. There was a dominance counselor gender interaction with working alliance scores. Clients who had problems with dominance reported higher working alliance scores with male counselors while clients who had problems with submissiveness reported higher working alliance scores with female counselors. Hostile dominance interpersonal problems were associated with lower initial working alliance scores regardless of counselor gender. Implications for clinical practice are discussed. / Dissertation/Thesis / M.C. Counseling Psychology 2012

Posttraumatic stress disorder (PTSD) symptoms and substance use have been associated with increased suicide ideation, but have rarely been examined within a larger theoretical context of suicide risk. The interpersonal theory of suicide posits that feeling disconnected from others (i.e., thwarted belongingness) and feeling like a burden on others (i.e., perceived burdensomeness) are associated with increased suicide ideation. We hypothesized that perceived burdensomeness and thwarted belongingness would mediate the relation between PTSD symptoms and suicide ideation, and that using substances to cope would moderate these relations. Participants were 254 college students reporting exposure to potentially traumatic experiences. Findings from a moderated mediation analysis indicated that perceived burdensomeness, but not thwarted belongingness, mediated the relation between PTSD symptoms and suicide ideation, and using substances to cope moderated this relation. Therapeutic interventions aimed at reducing suicide ideation might benefit from decreasing perceived burdensomeness and the use of substances to cope.
