Latent Structure of Antisocial and Borderline Personality Disorders: A Taxometric Research

Abstract

Resumo A identificação dos transtornos da personalidade como entidades categóricas ou contínuas ainda está sob investigação na psiquiatria e psicologia. No que diz respeito aos transtornos de personalidade antissocial (TPA) e borderline (TPB), análises taxométricas têm revelado resultados controversos, logo, inconclusivos. Partindo disso, este estudo buscou empregar métodos taxométricos na investigação da estrutura latente dos TPA e BPD. Foram analisados taxometricamente indicadores relacionados aos TPA e BPD do Inventário Dimensional Clínico da Personalidade (IDCP) em uma amostra clínica (N = 282; 63,5% mulheres; idade média = 38,38, com DP = 13,59) e outra da população geral (N = 7.091; 78,8% mulheres; Idade média = 22,20, com DP = 8,51). Os índices CCFI médios foram 0,276 para TPA e 0,401 para BPD. Os achados parecem refutar a perspectiva nosográfica categórica tradicional enquanto uma adequada perspectiva de modelagem latente de ambos os transtornos, além disso, sugerindo, claramente, uma estrutura dimensional para o TPA.

Dependency, mood instability, and inconsequence traits for discriminating borderline personality disorder

“…Several personality dimensions could be acknowledged as pertinent to BPD; however, conceptually and as in line with previous studies, 13,14 we highlight the dimensions of dependency, mood instability, and inconsequence, since they include factors related to separation insecurity, oscillation and emotional vulnerability, as well as impulsiveness and extreme reactions. [16][17][18][19] The aim of this study was to investigate the most discriminant IDCP-2 dimensions and factors to distinguish people diagnosed with BPD from people without this diagnosis.…”

“…3 The IDCP-2 comprises 206 items rated on a Likert scale ranging from 1 ("it has nothing to do with me") to 4 ("it has a lot to do with me"). The IDCP-2 comprises 12 dimensions (divided into 47 factors); however, based on previous studies with the IDCP, 13,14 we selected the dimensions and factors more strongly related to BPD, i.e., dependency 17 (self-devaluation, avoidance of abandonment, and insecurity), mood instability 18 (vulnerability, anxious worry, and hopelessness), and inconsequence 16 In relation to the first three charts in Figure 1, the BPD group showed the highest means in all cases, and the community sample tended to have the lowest means in almost all cases (except for inconsequence factors).…”

“…1,2,6,8,9 Some of these BPD features have been considered as indicators of personality impairment severity. 10,11 Based on the prominent literature about dimensional models of PDs, the self-report test Dimensional Clinical Personality Inventory (Inventário Dimensional Clínico da Personalidade [IDCP]) [12][13][14] has shown accuracy in the evaluation and identification of traits associated with BPD. Although no study has been published testing the accuracy of the revised version of the IDCP (i.e., IDCP-2), 15 results found with the first version of the IDCP can be generalized to the dimensions of IDCP-2, since the correlation between the total scores of the two versions tends to be around 0.90.…”

“…Embora esta tenha sido uma proposta bastante aceita, novos estudos têm suportado uma estrutura dimensional para esse e outros transtornos de personalidade. Dessa forma, sugere--se que novos estudos considerem essa nova perspectiva nas análises de dados (Carvalho et al, 2019;Hauck Filho et al, 2009). Agradecimentos Não há menções.…”
