Objetivo: A variabilidade nos relatos de dor tem sido um tema relativamente
negligenciado, apesar de trabalhos recentes sugerirem um impacto importante
na avaliação da dor. O paradigma Focused Analgesia Selection Test (FAST)
avalia esta variabilidade, mas os estudos sobre este paradigma são ainda
escassos. Esta dissertação estuda a relação entre este paradigma e a
vulnerabilidade a pistas internas e/ou externas, sugerindo que indivíduos que se
focam mais nas primeiras demonstrarão menor variabilidade comparando com
os indivíduos que se focam nas segundas.
Participantes e método: 13 participantes realizaram o FAST que avalia
variabilidade nos relatos de dor e a Rubber Hand Illusion (RHI) que avalia a
vulnerabilidade a pistas externas, através de medidas subjetivas (questionário
de pertença subjetiva), comportamentais (Deriva Proprioceptiva) e fisiológicas
(resposta galvânica) em duas condições (síncronas e assíncronas). Foi ainda
aplicado o questionário de Avaliação Multidimensional de Consciência
Interoceptiva para avaliar a consciência Interoceptiva e a Escala de Consciência
de Si Próprio, para avaliar estilos de Consciência de Si.
Resultados: Verificaram-se correções significativas entre a Deriva
Proprioceptiva na condição assíncrona da RHI com o FAST e, entre a
consciência interoceptiva na subescala “Não se Preocupar e “Confiar” e o FAST.
A Deriva Proprioceptiva na Condição Assíncrona correlacionou-se com as
subescalas “Não se distrair” e “Não se preocupar” da Consciência Interoceptiva.
A Consciência de Si Próprio Privada e a Deriva Proprioceptiva também se
correlacionaram na condição síncrona.
Conclusão: Uma menor variabilidade nos relatos de dor parece relacionar-se
com maior resistência a pistas táteis. Diferentes tipos de pistas externas poderão
ter valorizações distintas. A forma como o indivíduo processa pistas externas ou
internas é relevante para a perceção e as pistas externas não devem ser
entendidas necessariamente como fonte de distorção, podendo reduzir efeitos
de manipulação e sugestibilidade. Mais estudos são essenciais para aprofundar
estas questões e o seu impacto na avaliação da dor.
Purpose: Variability in pain reports has been a relatively neglected topic despite recent work suggesting an important impact on pain assessment. The Focused Analgesia Selection Test (FAST) paradigm assesses this variability, but studies on this paradigm are still scarce. This dissertation studies the relation between this paradigm and the vulnerability to internal and/or external cues, suggesting that individuals who focus more on the former will demonstrate less variability compared to individuals who focus on the latter. Participants and method: 13 participants performed the FAST that assesses variability in pain reports and the Rubber Hand Illusion (RHI) that assesses vulnerability to external cues, through subjective (subjective belongingness questionnaire), behavioral (Propriceptive Drift) and physiological (galvanic response) measures in two conditions (synchronous and asynchronous). The Multidimensional Assessment of Interoceptive Awareness questionnaire was also applied to assess interoceptive awareness and the Self-Awareness Scale to assess styles of self-awareness. Results: There were significant correlations between Proprioceptive Drift in the asynchronous condition of the RHI and the FAST, and between Interoceptive Awareness in the subscale "Not-Worrying” and "Trusting" and the FAST. Proprioceptive Drift in the Asynchronous Condition correlated with "NotDistracting" and "Not-Worrying" subscales of Interoceptive Awareness. Private Self-Awareness and Proprioceptive Drift also correlated in the synchronous condition. Conclusion: Lower variability in pain reports may be related to higher resistance to tactile cues. Different types of external cues can have different valuations. The way an individual processes external or internal cues is relevant for perception, and external cues should not necessarily be perceived as a source of distortion because they may reduce manipulation and suggestibility effects. More studies are essential to further explore these issues and their impact on pain assessment.
