Objective: Psychopathology research has relied on discrete diagnoses, which neglects the unique manifestations of each individual’s pathology. Borderline personality disorder combines interpersonal, affective, and behavioral regulation impairments making it particularly ill-suited to a “one size fits all” diagnosis. Clinical assessment and case formulation involve understanding and developing a personalized model for each patient’s contextualized dynamic processes, and research would benefit from a similar focus on the individual. Method: We use group iterative multiple model estimation, which estimates a model for each individual and identifies general or shared features across individuals, in both a mixed-diagnosis sample (N=78) and a subsample with a single diagnosis (n=24). Results: We found that individuals vary widely in their dynamic processes in affective and interpersonal domains both within and across diagnoses. However, there was some evidence that dynamic patterns relate to transdiagnostic baseline measures. We conclude with descriptions of two person-specific models as an example of the heterogeneity of dynamic processes. Conclusions: The idiographic models presented here join a growing literature showing that the individuals differ dramatically in the total patterning of these processes, even as key processes are shared across individuals. We argue that these processes are best estimated in the context of person-specific models, and that so doing may advance our understanding of the contextualized dynamic processes that could identify maintenance mechanisms and treatment targets.

Abstract. Psychiatric hospitalization can cause significant distress for patients. Research has shown that to cope with the stress, patients sometimes resort to self-harm. Given the paucity of research on self-harm among psychiatric inpatients, a better understanding of transdiagnostic processes as predictors of self-harm during psychiatric hospitalization is needed. The current study examined whether coping styles predicted self-harm after controlling for commonly associated factors, such as age, gender, and borderline personality disorder. Participants were 72 patients (mean age = 39.32 years, SD = 12.29, 64% male) admitted for inpatient treatment at a public psychiatric hospital in Sydney, Australia. Participants completed self-report measures of coping styles and ward-specific coping behaviors, including self-harm, in relation to coping with the stress of acute hospitalization. Results showed that younger age, diagnosis of borderline personality disorder, and higher emotion-oriented coping were associated with self-harm. After controlling for age and borderline personality disorder, higher levels of emotion-oriented coping were found to be a significant predictor of self-harm. Findings were partially consistent with hypotheses; emotion-oriented but not avoidance-oriented coping significantly predicted self-harm. This finding may help to identify and provide psychiatric inpatients who are at risk of self-harm with appropriate therapeutic interventions.

Abstract. One of the most common personality disorders among adolescents and young adults is the Borderline Personality Disorder (BPD). The objective of current study was to assess three questionnaires that can reliably screen for BPD in adolescents and young adults (N = 53): the McLean Screening Instrument for BPD (MSI-BPD; Zanarini et al., 2003 ), the Personality Diagnostic Questionnaire 4th edition – BPD scale (PDQ-4 BPD; Hyler, 1994 ), and the SCID-II Patient Questionnaire – BPD scale (SCID-II-PQ BPD). The nine criteria of BPD according to the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV; APA, 1994 ) were measured with the Structural Clinical Interview for DSM-IV Axis II disorders – BPD scale (SCID-II; First, Spitzer, Gibbon, Williams, & Benjamin, 1995 ). Correlations between the questionnaires and the SCID-II were calculated. In addition, the sensitivity and specificity of the questionnaires were tested. All instruments predicted the BPD diagnosis equally well.
