“…Mean alexithymia scores were comparable to other studies using clinical samples with the TSIA (Bagby et al, 2006) and the M-BIQ (Haviland et al, 2002), and slightly higher for the TAS-20 (Taylor et al, 2003) and the OAS (Haviland, Warren, Riggs, & Gallacher, 2001). Internal consistency was good for all total scores and most subscales.…”

“…The few studies exploring the convergence among alexithymia measures do not provide consistent evidence of their convergent validity. Sometimes correlations with large effect sizes (r ≈ .50) are found Haviland, Warren, Riggs, & Nitch, 2002), yet more often correlations are in the small (r ≈ .10) to medium (r ≈ .30) effect size range with sometimes even negative correlations between subscales of different instruments (Berthoz, Haviland, Riggs, Perdereau, & Bungener, 2005;Lumley, Gustavson, Partridge, & Labouvie-Vief, 2005).…”

The Convergence of Alexithymia Measures

The construct of alexithymia is most frequently measured by means of the 20-item Toronto Alexithymia Scale . However a number of other instruments have been developed to compensate for problems with measuring alexithymia through self-report measures. Convergence between the different alexithymia measures is rarely studied. This study investigates the convergence among the TAS-20, the Observer Alexithymia Scale (OAS), the Toronto Structured Interview for Alexithymia (TSIA), the modified Beth Israel Hospital Psychosomatic Questionnaire (M-BIQ), and the alexithymia dimensions as judged by the treating psychologist in an inpatient sample (N = 80). Correlations between the total scores were all significant. However exploratory factor analyses of these measures and their subscales indicate that they do not tap into one underlying factor. It is concluded that the TSIA and the M-BIQ are the best indicators of alexithymia, yet a multi-method approach and care in interpreting results are warranted.

“…This measure was subsequently modified to become a 12-item rating scale that assesses both the lack of emotional awareness and the tendency for operational thinking . Several studies have used the original or modified BIQ as the criterion against which other alexithymia measures have been validated, perhaps because the BIQ captures the original, clinically based manifestations of alexithymia Haviland, Warren, Riggs, & Nitch, 2002). Yet, the BIQ is not widely used, probably because of the challenges of training, the time needed for an interview, the lack of a standardized interview to elicit the information, and problems in obtaining acceptable interrater reliability.…”

“…The 33-item Observer Alexithymia Scale (OAS; Haviland, Warren, & Riggs, 2000) was developed on the assumption that alexithymia manifests in features-lack of insight, distance, somatizing, lack of humor, ridigity-that can be reliably reported by those who know the target person well such as family members, friends, or therapists. This measure has been shown to correlate highly with the modified BIQ (r = .69) when both measures were completed by the same therapists about the same patients (Haviland et al, 2002), and it also differentiates clinical from nonclinical cases (Haviland, Warren, Riggs, & Gallacher, 2001) and predicts a lack of interference on the emotional Stroop Test (Mueller, Alpers, & Reim, 2006). Generally, however, this relatively new measure has not been widely tested, so its validity for predicting criteria of clinical relevance is unknown.…”

“…Embora a TAS seja o instrumento de avaliação da alexitimia mais utilizado em pesquisas na atualidade, três outros instrumentos merecem referência: o Vorst Alexithymia Questionnaire (Bermont & Vorst, 1998 citado por Taylor, Bagby & Luminet, 2000), de auto-relato; o California Q-set Alexithymia Prototype -CAQ-AP (Haviland, 1998;Haviland & Reise, 1996a), com duas versões: auto-relato e avaliado pelo observador; e a Observer Alexithymia Scale -OAS (Haviland, Warren & Riggs, 2000;Haviland, Warren, Riggs & Gallacher, 2001;Haviland, Warren, Riggs & Nitch, 2002). Vale destacar ainda, que a OAS foi desenvolvida a partir do CAQ-AP e se encontra em fase de adaptação e validação para o português (Carneiro, 2006).…”

ResumoForam estudadas propriedades psicométricas da versão em português da Toronto Alexithymia Scale-TAS, em uma amostra de 294 pacientes internados em hospital geral por diversas patologias. Os resultados mostraram boa consistência interna (a = 0,72), e precisão de teste e reteste (r = 0,72). Análise fatorial sugeriu que um modelo de três dimensões pode ser mais adequado para esta população. Os itens do primeiro fator estão associados à habilidade para identificar os sentimentos e distingui-los de sensações corporais. Os itens do segundo fator relacionam-se a um estilo concreto de pensamento. Os itens do terceiro fator relacionam-se à habilidade de expressão de afetos e fantasias (daydreaming). Conclui-se que a alexitimia, conforme avaliada pela versão em português da TAS, é multidimensional não sendo bem representada por um escore global de severidade. Palavras-chave: Emoção; afeto; auto-relato. AbstractPsychometric properties of the Portuguese version of the Toronto Alexithymia Scale -TAS were studied in a sample of 294 inpatients with different pathologies, assisted at a general hospital. Results showed good internal consistency (a = 0,72) and test-retest reliability (r= 0,72). For this population the data were best represented by a three-factor structure. The items on the first factor are associated with the ability to identify one's feelings and to distinguish them from bodily sensations. The items on the second subscale relate to a concrete style of thinking. The items on the third subscale pertain to daydreaming and imagination. In conclusion, alexithymia, as measured by the Portuguese version of the TAS, is multidimensional and not well-represented by a global severity score. Keywords: Emotion; affect; self-report.Ainda que a natureza específica da alexitimia não tenha sido de todo elucidada, desde que proposta nos anos 70 por Sifneos (1972Sifneos ( /1977, há um consenso entre os autores de que ela representa um construto multidimensional relativo a um déficit no processamento cognitivo e de regulação das emoções que se tornam indiferenciadas e são pobremente reguladas (Haviland, Shaw, MacMurray & Cummings, 1988). Como conseqüência, o sujeito tende a responder a situações estressantes e/ou conflituosas através de ações que não são reconhecidas como tendo conteúdo afetivo (Martinez-Sánchez, Ato-García & OrtizSoria, 2003). Observa-se, ainda, uma reduzida capacidade de fantasiar e um padrão de pensamento voltado para os eventos exteriores, com ênfase nos detalhes. Esta forma de pensar apresenta grande semelhança com o pensamento operatório proposto por Marty e de M' Uzan (1963Uzan ( / 1994. Isto é, um estilo de pensamento caracterizado por falta de fantasia e de sonhos, que têm relação óbvia com os resíduos diurnos. A atividade mental é concreta e orientada para o presente, sem relação com fantasias inconscientes.Ao longo do tempo, o conceito de alexitimia foi sendo ampliado para se ajustar às observações que apontavam não se tratar de uma característica exclusiva de pacientes psicossomáticos, como inicia...
