The objectives of this paper were to study if the traits of the Positive Personality Model (PPM; de la Iglesia and Castro Solano, in Front Psychol 9:2025, 2018) were stable throughout time, if patients perceived change in psychotherapy process, and if positive traits at the beginning of the treatment (Time 1) predicted psychotherapy progress after 3 (Time 2) and 6 (Time 3) months of psychological treatment. The sample was composed of 38 subjects, with a mean age of 38.82 (SD = 12.76; 63.2% female; 36.8% male), who had just initiated psychotherapy treatment (Time 1). Results of a repeated measures ANOVA indicated that there were no statistically significant differences in the positive traits within the three moments that were measured. On the contrary, the level of perceived (lack of) psychotherapy progress diminished significantly in each assessment. Since the measure is reversed, this indicates an increment in the self-perception of the patients regarding the progress in psychotherapy. Moreover, a model in which the positive traits in Time 1 were predictors of psychotherapy progress in Time 2 and in Time 3 resulted statistically significant. Of all the positive traits, sprightliness was the only significant predictor. It is concluded that positive traits are characterized by stability throughout time and that, once again, sprightliness stands out as the main predictor of desirable outcomes.

本文的目的是研究积极人格模型（PPM; de la Iglesia and Castro Solano，in Psychol 9：2025，2018）的特征在整个时间内是否稳定，患者是否感到心理治疗过程发生了变化以及是否在治疗开始（时间1）的阳性特征预测的心理治疗3（时间2）和6（时间3）个月后，心理治疗的进展。样本由38位受试者组成，平均年龄为38.82（SD = 12.76; 女性63.2％; 36.8％的男性）刚刚开始接受心理治疗（时间1）。重复测量的方差分析结果表明，在测量的三个瞬间内，阳性特征在统计学上没有显着差异。相反，在每次评估中，感知到的（缺乏）心理治疗进展的水平显着降低。由于该措施被逆转，这表明在心理治疗方面，患者的自我感觉有所提高。此外，其中时间1的阳性特征是时间2和时间3的心理治疗进展的预测指标的模型具有统计学意义。在所有积极特征中，敏捷是唯一重要的预测指标。结论是，积极特质的特点是始终保持稳定，
