Identifying within-person dynamic factors influencing personality functioning (operationalized as self- and interpersonal functioning) above maladaptive personality traits could increase the applicability of the alternative DSM-5 model and help inform clinical interventions of personality difficulties. Founded in the metacognitive model of psychological disorders, we conducted a four-wave longitudinal survey study, where 1418 individuals aged 18 or above were recruited using convenience sampling. We used latent growth modelling to investigate whether metacognitive beliefs, emphasized as a mechanism of disorder in the metacognitive model, predicted the trajectory of self- and interpersonal functioning within individuals over time beyond baseline maladaptive personality traits. The results were that all personality traits were significantly associated with self- and interpersonal functioning at baseline, except for anankastia for the self-factor. Further, all metacognitive belief domains except cognitive self-consciousness for the interpersonal functioning factor showed an additional contribution across self- and interpersonal functioning over time. Overall, negative metacognitive beliefs was the strongest individual predictor among the metacognitive domains followed by cognitive confidence. These findings suggests that targeting metacognitions could be relevant for treatment aiming to increase personality functioning even beyond maladaptive personality traits. Treatment implications related to the within-person level of analysis based on these results are briefly discussed.
