BACKGROUND AND OBJECTIVES: Catastrophization and social support influence health outcomes in people with chronic pain. However, there is still no consensus regarding the relationship between these factors, and the information available in what relates to chronic pain in the knee joint is even scarcer. The objective of this study was to describe and understand the relationship between the perceived social support and pain catastrophization in adults with chronic knee pain.

METHODS: Sociodemographic data were collected, and the West Haven-Yale Multidimensional Pain Inventory and Pain Catastrophizing Scale were completed by the participants. The sample included 28 participants attending daycare institutions in Aveiro, Braga and Leiria districts (Portugal).

RESULTS: Seventy-five percent of the participants presented clinically significant catastrophization, and 64.3% reported high perceived social support. There is a direct relationship between high catastrophization and frequent solicitations and distraction responses. Conversely, an inverse association between high catastrophization levels and infrequent negative responses was observed in the collected sample.

CONCLUSION: Useful social support contributes to a maladaptive response to pain by increasing catastrophization levels, and the catastrophic response may be a way to ask for support. There is a direct association between the perceived social support and the catastrophization of chronic knee pain in the participants. However, the association between these variables was poor/low evidencing the need to consider other factors in the catastrophization study.

JUSTIFICATIVA E OBJETIVOS: Tanto a catastrofização como o suporte social influenciam os resultados na saúde de indivíduos com dor crônica. Porém, não há consenso sobre a relação entre esses fatores, sendo escassa a informação direcionada à articulação do joelho. O objetivo deste estudo foi descrever e compreender a relação entre o suporte social percebido e a catastrofização da dor em idosos com dor crônica do joelho.

MÉTODOS: Foi feita a coleta de dados sociodemográficos, em conjunto com o preenchimento dos instrumentos West Haven-Yale Multidimensional Pain Inventory e Pain Catastrophizing Scale pelos participantes. A amostra foi constituída por 28 participantes, institucionalizados em regime de centro de dia dos distritos de Aveiro, Braga e Leiria (Portugal).

RESULTADOS: Setenta e cinco por cento dos participantes apresentaram catastrofização clinicamente significativa e 64,3% referiram alto suporte social percebido. Verificou-se uma relação diretamente proporcional entre a elevada catastrofização e as respostas solícitas e de distração frequentes. Contrariamente, existe uma associação inversamente proporcional entre o elevado nível de catastrofização e as respostas negativas pouco frequentes na amostra recolhida.

CONCLUSÃO: O suporte social útil contribui para uma resposta desadaptativa à dor, pelo aumento dos níveis de catastrofização, podendo a resposta catastrófica constituir um meio para solicitar apoio. Denota-se uma associação diretamente proporcional entre o suporte social percebido e a catastrofização da dor crônica do joelho nos participantes. Contudo, a relação demonstrou ser pobre/baixa, evidenciando a necessidade de considerar outros fatores no estudo da catastrofização.
