INTRODUCTION
Personality and psychopathology have been variably associated along history.1 Their interactions may exist in different forms and may be associated with a model of vulnerability, as certain disordered personality traits may predispose to psychopathology (e.g., clinical depression).2
Various personality models and structures have been described, and current models suggest that personality is hierarchically organized, with broad higher-order (molar) traits that subdivide into specific lower-order (facet) traits.3 The Five Factor Model (FFM), the most widely accepted model of normal personality,4 has been used extensively in studies of depression, but it is weighted to molar constructs and, therefore, has some limitations.5, 6 As most personality dimensions show some level of interdependence, a hierarchical model that includes molar constructs and their constituent facets may overcome those limitations to some degree. Furthermore, the FFM is limited in that it does not assess some personality styles relevant to a predisposition to depressive disorders, such as rejection sensitivity, a central feature of atypical depression.7
Parker et al.7 suggested that some forms of non-melancholic depression are a consequence of predisposing personality styles and undertook several studies to define and refine such candidate personality styles.6 - 11 Their studies have led to a flexible self-report measure of personality,6 the Temperament & Personality Questionnaire (T&P).12 This tiered instrument is used to evaluate molar constructs and a series of lower-order personality styles overrepresented in individuals with depressive disorders according to a bottom-up approach irrespective of any model of personality. Although its English version has been used in numerous studies, T&P has been minimally used in other languages.13 This report summarizes the process of translation and cultural adaptation (TCA) of the T&P from English into Brazilian Portuguese and briefly describes its final version.
METHODS
The Temperament & Personality Questionnaire (T&P)
The T&P is a 109-item self-report questionnaire with 10 subscales, eight for the assessment of personality styles (89 items) and two for disordered personality functioning (10 items for non-cooperativeness and 10 for ineffectiveness). Each item is rated on a 4-point scale (0 = not true at all; 1 = slightly true; 2 = moderately true; and 3 = very true). The T&P is hierarchically organized and scored across two to eight progressively divergent tiers. At the eight-tier level, molar neuroticism and introversion scores are generated, and the eighth tier has all eight personality facets (anxious worrying, personal reserve, perfectionism, irritability, social avoidance, rejection sensitivity, self-criticism and self-focused).
Intermediate tiers are derived from molar tiers. For instance, the personality style anxious worrying/sensitivity to other at the fifth tier splits into 'anxious worrying' and 'rejection sensitivity' at the sixth tier, with both lower-order dimensions of the higher-order molar neuroticism construct. The T&P is available for use free of charge and can be completed in a pen-and-paper format or online in the Black Dog Institute Website (www.blackdoginstitute.org.au). The psychometric properties of the original English version of T&P were tested in Australian samples and results revealed high internal consistence across its eight subscales (Cronbach's α coefficients ranging from 0.62 to 0.91) and high test-retest reliability (intra-class correlation ranging from 0.72 to 0.93). The questionnaire had minimal sensitivity to mood state effects and concurrent validity against clinically judged construct scores.6
The authors of this study developed a Portuguese version of the T&P, as described here, and evaluated its psychometric properties, described in another manuscript.14
Procedures
The procedures for translation and adaptation of the T&P followed guidelines for adapting self-report instruments issued by the Task Force for Translation and Cultural Adaptation of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR).15 These guidelines are widely used for translation and adaptation of self-report instruments in various health areas. A detailed discussion of this method was published by our research group in a study for the translation and adaptation of the Measure of Parental Style (MOPS).16
Briefly, the translation process had 10 steps15:
1) Preparation: initial work, before the translation process;
2) Forward translation: first translation into the target language;
3) Reconciliation: building a single version merging more than one forward translation;
4) Back translation: translation of the reconciliation version back into the original language;
5) Back translation review: comparison of back-translated versions with the original to investigate discrepancies;
6) Harmonization: comparison of back translation versions with each other and the original instrument to harmonize discrepancies between the reviewed version of the back translation and the original instrument;
7) Cognitive debriefing: application of the instrument to a small number of patients with depression to check understandability, interpretation and cultural relevance of the translation;
8) Review of cognitive debriefing results and finalization;
9) Proof reading; and
10) Final report.
The translation of T&P started after the author of the original instrument (GP) had been contacted and granted authorization (preparation phase). The first (forward) translations were made by four native speakers of the target language, in two pairs, producing two independent translations. The reconciliation version was produced by a native speaker of the target language not involved in the forward translations.
The back translation was performed by an independent translator, not linked to the project, and who did not know the original instrument or the first translations. The revision of the back translation was performed by the author of the original T&P (GP).
Five patients with depression were recruited for the cognitive debriefing at de Mood Disorders Program, an outpatient service of Hospital de Clínicas de Porto Alegre (HCPA) in southern Brazil. The investigation was approved by the medical ethics committee of HCPA, and all participants provided written informed consent.
RESULTS
Table 1 summarizes the results of the two initial translations, conciliation, back translation and final version. The author's comments suggested adjustments to only eleven items (items 5, 14, 15, 20, 32, 76, 80, 88, 102, 108 and 109) of the questionnaire, and changes and adjustments were accepted by the Brazilian research group.

After revision of the back translation, the Brazilian version of the T&P was applied to five outpatients with depression whose native language was Portuguese. For each item, the patients were asked what they understood and whether they had any difficulties or suggestions (cognitive debriefing). This step produced minor adaptations that were incorporated into the final version, along with syntax and spelling revisions. For example, in item 39 (I like lots of social stimulation) the word contato (contact in English) was placed in brackets to reinforce the meaning of the original sentence in English. We did not perform any harmonization, as there are no versions of the T&P in other languages to compare with our back translation.
DISCUSSION
This study briefly described the translation and cross-cultural adaptation of T&P into Brazilian Portuguese using the method prescribed by the TCA task force.15 To our knowledge, this is the first translation of T&P. The translation followed a standardized process and required minor adaptations.
This version of the T&P has already been used in Brazil in studies already published.13 In clinical settings, the T&P has advantages over other personality measures, as it assesses personality styles specifically overrepresented in patients with clinical depression and follows a bottom-up approach.7 Because of this structure, at the fourth tier each of its four personality styles is consistent with the big four factors of the dominant FFM of personality: anxious worrying/sensitivity to others in T&P is equivalent to neuroticism in FFM; irritability, to disagreeableness; perfectionism, to conscientiousness; and personal/social reserve, to introversion.6 Therefore, construct validity has been suggested for its original English version.
Another potential advantage is its flexible format of eight tiers, which allows for broad investigations that range from molar factors at its second tier to more fine-grained analyses examining up to eight factors at its eighth tier. It may be used in studies to investigate the association between personality and depression (e.g., risk of onset and response to treatment) as well as to examine specificity to non-melancholic depressive subtypes, such as atypical depression.17
In summary, the Brazilian version of the T&P was translated and adapted following rigid standardized international guidelines and is already available for use, although its validation is ongoing. Future adaptations to other languages should use the same process and be compared with our back translation. We believe that this versatile instrument may be especially useful to investigate the association between personality styles and depressive conditions.
