Very few empirically validated interventions for improving metacognitive skills (i.e., self-awareness and self-regulation) and functional outcomes have been reported. This single-case experimental study presents JM, a 36-year-old man with a very severe traumatic brain injury (TBI) who demonstrated long-term awareness deficits. Treatment at four years post-injury involved a metacognitive contextual intervention based on a conceptualization of neuro-cognitive, psychological, and socio-environmental factors contributing to his awareness deficits. The 16-week intervention targeted error awareness and self-correction in two real life settings: (a) cooking at home: and (b) volunteer work. Outcome measures included behavioral observation of error behavior and standardized awareness measures. Relative to baseline performance in the cooking setting, JM demonstrated a 44% reduction in error frequency and increased self-correction. Although no spontaneous generalization was evident in the volunteer work setting, specific training in this environment led to a 39% decrease in errors. JM later gained paid employment and received brief metacognitive training in his work environment. JM's global self-knowledge of deficits assessed by self-report was unchanged after the program. Overall, the study provides preliminary support for a metacognitive contextual approach to improve error awareness and functional Outcome in real life settings.

This study investigated the relationship between psychosocial risk factors and (1) neck symptoms and (2) neck pain and disability as measured by the neck disability index (NDI). Female office workers employed in local private and public organizations were invited to participate, with 333 completing a questionnaire. Data were collected on various risk factors including age, negative affectivity, history of previous neck trauma, physical work environment, and task demands. Sixty-one percent of the sample reported neck symptoms lasting greater than 8 days in the last 12 months. The mean NDI of the sample was 15.5 out of 100, indicating mild neck pain and disability. In a hierarchical multivariate logistic regression, low supervisor support was the only psychosocial risk factor identified with the presence of neck symptoms. Similarly, low supervisor support was the only factor associated with the score on the NDI. These associations remained after adjustment for potential confounders of age, negative affectivity, and physical risk factors. The interaction of job demands, decision authority, and supervisor support was significantly associated with the NDI in the final model and this association increased when those with previous trauma were excluded. Interestingly, and somewhat contrary to initial expectations, as job demands increased, high decision authority had an increasing effect on the NDI when supervisor support was low.

Em face da complexidade no ambiente de trabalho que exige maior dedicação por parte de seus ocupantes e com uma crescente exigência por desempenho destes indivíduos, o presente estudo teve por objetivo estudar a interdependência de algumas variáveis do comportamento organizacional, testando um modelo conceitual composto do capital psicológico, percepções de suporte e bem-estar no trabalho. Os participantes foram 152 trabalhadores que atuavam na Região Norte (Estado do Tocantins) e Região Sudeste (Estado de São Paulo) em organizações públicas e privadas. Como instrumento para coleta de dados foi utilizado um questionário de autopreenchimento composto de seis escalas que mediram as variáveis da pesquisa. A presente pesquisa se propôs a apresentar, interpretar e discutir as relações entre as variáveis, como também, testar as hipóteses referentes ao modelo conceitual proposto, por meio de uma pesquisa de natureza transversal com abordagem quantitativa, cujos dados coletados foram analisados por aplicação de técnicas estatísticas paramétricas (cálculos de estatísticas descritivas: médias, desvio padrão, teste t e correlações; cálculos de estatísticas multivariadas: análises de regressões lineares múltiplas hierárquicas e stepwise) por meio do software SPSS, versão 18.0. Os resultados obtidos demonstraram que os níveis das três dimensões de bem-estar no trabalho são impactados diretamente pelas percepções de suporte (social no trabalho e organizacional). Confirmou-se também, o capital psicológico como preditor direto das percepções de suporte (social no trabalho e organizacional). Por fim, este trabalho evidenciou que trabalhadores com um capital psicológico elevado tendem a perceber suporte, tanto social no trabalho como organizacional e, por conseguinte, trabalhadores que percebem suporte (social no trabalho e organizacional) tendem a manter vínculos com seu trabalho e com sua organização empregadora, os quais representam bem-estar no trabalho.
