ABSTRACT Severe traumatic brain injury (sTBI) often results in significant morbidity, with fewer than 50% returning to work and only a minority resuming leisure and social activity. Yet few effective interventions are available for non-vocational activity. The aim of the study was to develop a new goal-directed intervention, the Programme for Engagement, Participation and Activities (PEPA), and evaluate its effect. The research design was a multiple-baseline design across behaviours, with direct inter-subject and systematic replications. Seven participants with sTBI, neurobehavioural impairment including apathy, inability to work, and limited leisure/social activities were categorised into two groups. Group 1 (n = 4) had cognitive impairments but were functionally independent. Systematic replication was conducted in a further three participants (group 2) with major neurobehavioural impairments and functional disability. Generalisation measures evaluated other life domains in group 1 participants (e.g., mood, community participation). Results of the weighted average Tau-U across the tiers was significant for six out of seven participants, with large effect sizes (≥.64) for five participants. Generalisation effects extended to other domains of life. The PEPA thus shows promise as an effective intervention to increase non-vocational activity and improve mental health outcomes in people with neurobehavioural disability after sTBI. These results add to the evidence for the effectiveness of goal-directed interventions.

评估在严重创伤性脑损伤后增加有意义活动的干预措施:具有直接受试者间和系统复制的单例实验设计

摘要 严重创伤性脑损伤 (sTBI) 通常会导致显着的发病率,只有不到 50% 的人重返工作岗位,只有少数人恢复休闲和社交活动。然而,很少有有效的干预措施可用于非职业活动。该研究的目的是开发一种新的以目标为导向的干预措施,即参与、参与和活动计划 (PEPA),并评估其效果。研究设计是跨行为的多基线设计,具有直接的受试者间和系统复制。七名患有 sTBI、神经行为障碍(包括冷漠、无法工作和休闲/社交活动受限)的参与者被分为两组。第 1 组(n = 4)有认知障碍,但功能独立。在另外三名患有严重神经行为障碍和功能障碍的参与者(第 2 组)中进行了系统复制。概括测量评估了第 1 组参与者的其他生活领域(例如,情绪、社区参与)。七名参与者中有六名参与者的加权平均 Tau-U 结果显着,五名参与者的效应量大 (≥.64)。泛化效应扩展到生活的其他领域。因此,PEPA 有望成为一种有效干预措施,以增加 sTBI 后神经行为障碍患者的非职业活动并改善其心理健康结果。这些结果为目标导向的干预措施的有效性提供了证据。概括测量评估了第 1 组参与者的其他生活领域(例如,情绪、社区参与)。七名参与者中有六名参与者的加权平均 Tau-U 结果显着,五名参与者的效应量大 (≥.64)。泛化效应扩展到生活的其他领域。因此,PEPA 有望成为一种有效干预措施,以增加 sTBI 后神经行为障碍患者的非职业活动并改善其心理健康结果。这些结果为目标导向的干预措施的有效性提供了证据。概括测量评估了第 1 组参与者的其他生活领域(例如,情绪、社区参与)。七名参与者中有六名参与者的加权平均 Tau-U 结果显着,五名参与者的效应量大 (≥.64)。泛化效应扩展到生活的其他领域。因此,PEPA 有望成为一种有效干预措施,以增加 sTBI 后神经行为障碍患者的非职业活动并改善其心理健康结果。这些结果为目标导向的干预措施的有效性提供了证据。泛化效应扩展到生活的其他领域。因此,PEPA 有望成为一种有效干预措施,以增加 sTBI 后神经行为障碍患者的非职业活动并改善其心理健康结果。这些结果为目标导向的干预措施的有效性提供了证据。泛化效应扩展到生活的其他领域。因此,PEPA 有望成为一种有效干预措施,以增加 sTBI 后神经行为障碍患者的非职业活动并改善其心理健康结果。这些结果为目标导向的干预措施的有效性提供了证据。
