Dimensional models for classifying personality have received extensive empirical support in the treatment of substance misuse. However, we do not currently understand whether and which dimensions of personality functioning are amenable to change. The aim was to examine whether there are clinically significant changes between pre- and during-treatment and assess whether these differ between those completing or dropping out of treatment. From the 200 participants from the outpatient and 340 from the inpatient treatment, a purposeful selection was utilised of 75 cases that participated in both phases and had complete datasets of the assessment battery. A quantitative multi-site individual follow-up design allowed the examination of the potential effects of treatment in personality functioning as well as the degree of clinical significant change of personality functioning. We use Jacob and Truax's formula of reliable and clinically significant change. Five independent mixed between-within subject analyses of variance were performed. All personality adaptations changed towards higher-functioning levels, except Social Concordance, which remained stable. Compared to those dropping out, completers had significantly more changes towards functional characteristic adaptations and higher clinical improvement. The persistence of maladaptive characteristic adaptations may be an important risk marker for poor treatment outcomes, requiring therapeutic attention.
用于人格分类的维度模型在物质滥用治疗方面获得了广泛的实证支持。然而，我们目前并不清楚人格功能的哪些维度以及是否能够改变。目的是检验治疗前和治疗期间是否存在具有临床意义的变化，并评估完成治疗者和退出治疗者之间这些变化是否存在差异。从200名门诊参与者和340名住院治疗参与者中，有目的地选取了75例参与两个阶段且拥有完整评估数据集的病例。定量多地点个体随访设计允许检验治疗对人格功能的潜在影响以及人格功能具有临床意义的变化程度。我们使用雅各布和特鲁克斯关于可靠且具有临床意义变化的公式。进行了五项独立的主体间与主体内混合方差分析。除社会和谐性保持稳定外，所有人格适应性都朝着更高功能水平变化。与退出治疗者相比，完成治疗者在功能特征适应性方面有显著更多变化且临床改善程度更高。适应不良特征适应性的持续存在可能是治疗效果不佳的一个重要风险指标，需要给予治疗关注。
