This study evaluated whether providing intensive home treatment (IHT) to patients experiencing a psychiatric crisis has more effect on self-efficacy when compared to care as usual (CAU). Self-efficacy is a psychological concept closely related to one of the aims of IHT. Additionally, differential effects on self-efficacy among patients with different mental disorders and associations between self-efficacy and symptomatic recovery or quality of life were examined. Data stem from a Zelen double consent randomised controlled trial (RCT), which assesses the effects of IHT compared to CAU on patients who experienced a psychiatric crisis. Data were collected at baseline, 6 and 26 weeks follow-up. Self-efficacy was measured using the Mental Health Confidence Scale. The 5-dimensional EuroQol instrument and the Brief Psychiatric Rating Scale (BPRS) were used to measure quality of life and symptomatic recovery, respectively. We used linear mixed modelling to estimate the associations with self-efficacy. Data of 142 participants were used. Overall, no difference between IHT and CAU was found with respect to self-efficacy (B = − 0.08, SE = 0.15, p = 0.57), and self-efficacy did not change over the period of 26 weeks (B = − 0.01, SE = 0.12, t (103.95) = − 0.06, p = 0.95). However, differential effects on self-efficacy over time were found for patients with different mental disorders (F(8, 219.33) = 3.75, p < 0.001). Additionally, self-efficacy was strongly associated with symptomatic recovery (total BPRS B = − 0.10, SE = 0.02, p < 0.00) and quality of life (B = 0.14, SE = 0.01, p < 0.001). Although self-efficacy was associated with symptomatic recovery and quality of life, IHT does not have a supplementary effect on self-efficacy when compared to CAU. This result raises the question whether, and how, crisis care could be adapted to enhance self-efficacy, keeping in mind the development of self-efficacy in depressive, bipolar, personality, and schizophrenia spectrum and other psychotic disorders. The findings should be considered with some caution. This study lacked sufficient power to test small changes in self-efficacy and some mental disorders had a small sample size.

强化家庭治疗对精神病康复者自我效能的影响

这项研究评估了与精神照护相比，向精神病患者提供强化家庭治疗（IHT）是否对自我效能有更大的影响。自我效能感是与IHT的目标之一密切相关的心理概念。此外，还研究了不同精神障碍患者对自我效能的不同影响以及自我效能与症状恢复或生活质量之间的关联。数据来自Zelen双重同意随机对照试验（RCT），该试验评估了IHT与CAU相比对经历精神病患者的影响。在基线，6和26周的随访中收集数据。使用心理健康信心量表测量自我效能。使用5维EuroQol仪器和简短精神病评定量表（BPRS）来衡量生活质量和症状恢复。我们使用线性混合建模来估计与自我效能感的关联。使用了142名参与者的数据。总体而言，就自我效能而言，IHT和CAU之间没有差异（B = − 0.08，SE = 0.15，p = 0.57），并且自我效能在26周内没有变化（B = − 0.01， SE = 0.12，t（103.95）=-0.06，p = 0.95）。然而，对于患有不同精神障碍的患者，其自我效能随时间的变化存在差异（F（8，219.33）= 3.75，p <0.001）。此外，自我效能感与症状恢复（总BPRS B = − 0.10，SE = 0.02，p <0.00）和生活质量（B = 0.14，SE = 0.01，p <0.001）密切相关。尽管自我效能感与症状恢复和生活质量相关，但与CAU相比，IHT对自我效能感没有补充作用。这一结果提出了一个问题，即是否应该以及如何将危机护理调整为增强自我效能感，同时要牢记抑郁症，躁郁症，人格和精神分裂症谱系及其他精神病患者的自我效能感的发展。研究结果应谨慎考虑。这项研究缺乏足够的能力来测试自我效能的小变化，并且一些精神障碍的样本量很小。试用注册该试用在Trialregister.nl上注册，编号NL6020。这一结果提出了一个问题，即是否应该以及如何将危机护理调整为增强自我效能感，同时要牢记抑郁症，躁郁症，人格和精神分裂症谱系及其他精神病患者的自我效能感的发展。研究结果应谨慎考虑。这项研究缺乏足够的能力来测试自我效能的小变化，并且一些精神障碍的样本量很小。试用注册该试用在Trialregister.nl上注册，编号NL6020。这一结果提出了一个问题，即是否应该以及如何将危机护理调整为增强自我效能感，同时要牢记抑郁症，躁郁症，人格和精神分裂症谱系及其他精神病患者的自我效能感的发展。研究结果应谨慎考虑。这项研究缺乏足够的能力来测试自我效能的小变化，并且一些精神障碍的样本量很小。试用注册该试用在Trialregister.nl上注册，编号NL6020。这项研究缺乏足够的能力来测试自我效能的小变化，并且一些精神障碍的样本量很小。试用注册该试用在Trialregister.nl上注册，编号NL6020。这项研究缺乏足够的能力来测试自我效能的小变化，并且一些精神障碍的样本量很小。试用注册该试用在Trialregister.nl上注册，编号NL6020。
