Validation of the brief TEMPS-M temperament questionnaire in a clinical Italian sample of bipolar and cyclothymic patients
2020
Abstract Background To assess psychometric proprieties of the short version of
TEMPS-M in an Italian clinical sample of patients with bipolar disorder type I (BDI), type II (BDI) or
cyclothymic disorder(CYC). Methods All participants were recruited in two Italian university sites. They were asked to complete the Italian version of the short
TEMPS-M, consisting of 35 items on a five-point Likert scale ranging from 1 to 5. The factorial structure of the instrument was assessed by principal components analysis with
varimax rotation. The reliability of the subscales was assessed with
Cronbach's alpha. Results The 815 recruited patients had a diagnosis of BDI (430), CYC (227) or BDII (158); 60% of them were female and with a mean age of 44.4 (±14.6) years.
Cronbach's alphacoefficients of subscales ranged from 0.808 to 0.898. The factor analysis confirmed five dimensions (depressive, cyclothymic, hyperthymic, irritable, anxious), as in the English version of the scale. All
temperamentswere more represented in CYC than in BDI patients. Depressive and anxious
temperamentswere more represented in BDII than in BDI; the
hyperthymic temperamentwas represented more in BDI than in BDII patients. Limitations No other assessment instrument was used as a reference to assess the external or
predictive validityof
TEMPS-M; several socio-demographic and clinical characteristics have not been assessed. Conclusion The Italian version of the short
TEMPS-M shows good reliability and validity. It might be used in clinical and research settings, for the dimensional exploration of the investigated domains.
