Three joint temperament-character configurations account for learning, personality and well-being: normative demographic findings in a representative national population

Introduction

A common practice in research and clinical practice is to use data considered representative of a target population to compare and understand the personality characteristics of specific groups or specific individuals. To this end, numerous studies have presented normative data for the temperament and character traits outlined in Cloninger's psychobiological model of personality. However, recent genomic evidence demonstrates that human personality is organized as a complex hierarchy that ascends beyond the individual traits to multi-trait profiles that regulate emotional reactivity (temperament profiles) or goals and values (character profiles), and then to three phenotypic networks, which integrate temperament profiles and character profiles, that regulate learning. Given this recent understanding, our aim was to provide a novel and more comprehensive description of personality features at a societal level (using a stratified sample representative of the Portuguese population) by considering personality at its higher levels of complexity.

Methods

Toward this goal, a stratified sample of 2,443 Portuguese adults responded to the Revised Temperament and Character Inventory (TCI-R).

Results

We summarize the prevalence of (a) temperament profiles, (b) character profiles, and (c) integrated temperament-character networks within the whole sample, as well as for men vs. women and different age groups separately. Independent of age and education, women were more likely to be capable of resourceful productivity and helpful cooperation combined with being more intuitive, meditative and creative than men. Independent of age and gender, individuals with a degree were also more likely to present these biopsychosocial features. We also found that the organized character profile was most typical of adults in their 40s. Finally, the distribution of personality profiles across age differed as a function of gender: for men the oldest individuals had the most coherent personalities while high personality integration was most prevalent for women in their 30s.

Discussion

These results have strong implications for research and intervention. In particular, these results are relevant for understanding the epidemiology of interactions between personality, mental health and well-being, including their expressions in a national population as a function of demographic characteristics.

Temperament and character traits in patients with tinnitus: a prospective case series with comparisons

OBJECTIVE

To describe the personality traits of temperament and character in patients with tinnitus and to identify differences in these traits associated with the severity of tinnitus.

STUDY DESIGN

Case series with comparisons.

SETTING

Tertiary referral centre.

PARTICIPANTS

From January to December 2014, one hundred and thirty-four adult patients with chronic subjective tinnitus completed psychoacoustic measurements of tinnitus and the Temperament and Character Inventory (TCI).

MEASUREMENTS

Personality traits were assessed by the TCI. The TCI assesses seven dimensions of personality traits and four temperaments 'novelty seeking, harm avoidance, reward dependence, persistence', as well as three characters 'self-directedness, cooperativeness, self-transcendence'.

MAIN OUTCOME MEASURES

The values of the TCI parameters in the tinnitus patients were compared with reference data from a non-institutional adult population, and associations between TCI parameter values and tinnitus severity were evaluated.

RESULTS

In terms of temperament, tinnitus patients had higher scores for 'harm avoidance', whereas scores for 'novelty seeking', 'reward dependence' and 'persistence' were significantly lower than the reference. In terms of character, lower 'cooperativeness' and 'self-transcendence' were identified in the subjects with tinnitus. The 'novelty seeking' score was inversely related to tinnitus severity (r = -0.285, P = 0.001), while other temperament and character traits did not show significant correlations.

CONCLUSIONS

There may be a connection between tinnitus and personality traits, especially in the case of 'novelty seeking', which is relatively constant over a lifetime. The TCI questionnaire may be useful in facilitating the application of personality traits to tailored counselling for tinnitus.
