Personality Promotion: The Impact of Coaching and Behavioral Activation on Facet Level Personality Change and Health Outcomes

Personality change through a digital-coaching intervention: Using measurement invariance testing to distinguish between trait domain, facet, and nuance change

Recent intervention research has shown that personality traits can be modified through psychological interventions. However, it is unclear whether reported effects represent changes in the trait domain or only some facets or items. Using data ( N = 552) from a recent intervention trial, the present study examined the effects of a digital-coaching intervention on self- and observer-reported personality facets and items. We focused on participants who wanted to decrease in Negative Emotionality, increase in Conscientiousness or increase in Extraversion. We used measurement invariance testing to examine which level of the trait domain hierarchy changed during the intervention. For the self-reports, we found some heterogeneity in the effects on all three trait domains, but most notably Extraversion and Conscientiousness. Specifically, participants reported to increase strongly on sociability (Extraversion), and moderately on productiveness and organization (Conscientiousness), but not on the other facets of these trait domains. Observers generally reported small but non-significant changes, with no scalar invariance violations except for Extraversion. Overall, this suggests considerable heterogeneity in intervention-related personality change that can be overlooked if only focusing on the trait domain level. We discuss the relevance of measurement invariance testing and measurement approaches for personality development and intervention research.

Personality Change Through Digital-Coaching Interventions

A highly relevant but provocative research question is whether and how one can intentionally change personality traits through psychological interventions, given that traits are relatively stable by definition. Recently, research has begun to investigate personality change through intervention in nonclinical populations. One attractive and innovative interventional avenue may lie in using digital applications to guide and support people in their desire to change their personality and trigger change processes. This article provides a rationale for nonclinical personality-change interventions and discusses motivations to change, the potential of using digital applications for intervention efforts, key studies that illustrate this emerging field of research, and future directions.

Can exposure to arguments pro and contra extraversion affect self-reports of the trait and the attitude toward it?

OBJECTIVE

Changeability of personality over short-term intervals has increasingly become a focus of research. However, the role played by argumentation interventions in short-term variations has scarcely been examined.

METHODS

In two experiments (N = 363 and 320), we investigated how processing positive and negative argumentation regarding extraversion (Study 1: watching a lecture; Study 2: elaborating self-invented arguments) affects self-reports on this trait and attitude toward it. The experiments included three waves of measurements with argument manipulation (in favor of or against extraversion) immediately prior to Time 2 (Study 2 also included a control group).

RESULTS

Mean-level changes in extraversion across time moments, measured with the longitudinal confirmatory factor analysis, were consistently negligible. Conversely, there were some indications that argumentation about extraversion could have immediate short-term effects on attitudes toward this trait. The random-intercept cross-lagged model showed that rank-order consistency stemmed from a trait-like intercept, which was particularly large for trait extraversion compared with the attitude. The autoregressive and cross-lagged effects of residual within-person variation were consistently small and mostly nonsignificant.

CONCLUSION

Our findings suggest that extraversion and the attitude toward it maintained their temporal continuity within 3 months, even under a single exposure to arguments pro and contra this trait.

Self-reported occupational functioning in persons with relapsing-remitting multiple sclerosis: Does personality matter?

BACKGROUND

Multiple sclerosis (MS) poses a major threat to sustainable employability. Identifying conditions and factors that promote work participation is of great importance. Our objective was to explore the contribution of personality traits in explaining occupational functioning in MS.

METHODS

241 participants with relapsing-remitting MS (78% female, median age: 42.0 years, median EDSS: 2.0) and 60 healthy controls (70% female, median age: 45.0 years) underwent neuropsychological and neurological examinations and completed questionnaires. Multivariate logistic and linear regression analyses were conducted to examine relations between personality traits and self-reported occupational functioning, while accounting for known correlates.

RESULTS

Personality traits were not associated with self-reported occupational functioning when correcting for known correlates. A higher impact of fatigue (B = -0.05, p = .005 and B = -0.04, p = .009) and depression (B = -0.22, p = .008 and B = -0.21, p = .01) were associated with no paid job (R² = 0.13) and considering to reduce work hours (R² = 0.12). A higher impact of fatigue (B = -0.05, p = .008, β = 0.46, p = .001 and β = -0.36, p = .001) was associated with absenteeism from work (R² = 0.15), more presenteeism (R² = 0.35) and lower work ability (R² = 0.25). A higher impact of fatigue (β = 0.46, p = .001) and anxiety (β = 0.25, p = .001) were associated with more work difficulties (R² = 0.54).

CONCLUSION

Personality traits did not explain additional variance in self-reported occupational functioning in persons with relapsing-remitting MS with mild disability. The impact of fatigue was the main and most consistent correlate of occupational functioning, often combined with depression or anxiety. Total explained variance of the models was limited, emphasizing the need to additionally examine other (contextual) factors when considering occupational challenges in MS.
