Depression symptoms' impact on personality disorder treatment: Depression symptoms amplifying the interpersonal benefits of negative-affect expression

BACKGROUND

While there is some evidence that patients with elevated depression symptoms experience greater benefits from negative-affect expression, this amplifying effect has not been investigated within a psychotherapeutic context. This is particularly notable considering the substantial evidence linking affect expression with desired outcomes across psychotherapeutic approaches. The primary purpose of the present study was to investigate if depression symptoms amplified (i.e., moderated) the association between negative-affect expression and reductions in interpersonal problems for patients in a psychiatric day treatment for personality disorders. The secondary purpose was to investigate milieu (i.e., other patients concurrently enrolled) negative-affect intensity and its association with patients' reductions in interpersonal problems.

METHODS

Participants (N = 239) were patients consecutively admitted into a psychiatric day treatment program for people with personality disorders. Patients completed measures of (1) depression symptoms at pre-treatment, (2) interpersonal problems at pre- and post-treatment, and (3) negative-affect expression each week of treatment.

RESULTS

The association between patient negative-affect expression and reductions in interpersonal problems was amplified by depression symptoms. Depression symptoms also amplified the association between milieu negative-affect intensity and reductions in interpersonal problems.

CONCLUSIONS

Our findings indicate that depression symptoms amplified the therapeutic value of negative-affect expression and amplified the value of an affectively intense milieu. Practical and theoretical implications are discussed.

Low positive affect display mediates the association between borderline personality disorder and negative evaluations at zero acquaintance

BACKGROUND

Several recent studies have demonstrated that naïve raters tend to evaluate individuals with Borderline Personality Disorder (BPD) negatively at zero-acquaintance (i.e., in a 'first impression' type situation, where the rater has no knowledge of the individual and no prior interactions with them). Specifically, individuals with BPD were evaluated as less trustworthy, likeable, and cooperative than healthy participants (HCs). Based on previous impression formation studies, we hypothesized that the non-verbal cues positive affect display, negative affect display, and eye contact contribute to negative first impressions of those with BPD.

METHODS

To address this question, we recruited 101 participants that rated the degree of positive affect display, negative affect display, and eye contact in 52 videos of age-and gender-matched BPD and HC participants. We hypothesized that low positive affect display, high negative affect display, and eye contact would mediate the association between group (BPD vs. HC) and ratings of trustworthiness, likeability, and cooperativeness.

RESULTS

Ratings for positive affect display were significantly lower and those for negative affect display significantly higher for BPD versus HC targets, whereas eye contact did not differ significantly between groups. In multiple mediation models, positive affect display significantly mediated the association between group and trustworthiness/likeability, whereas negative affect display only mediated the association between group and likeability. None of the individual cues was a significant mediator of the association between group and cooperation.

CONCLUSIONS

We emphasize therapeutic possibilities to improve positive affect display -and thus overall first impressions- to increase the chances of forming social bonds for BPD individuals.
