Healthcare worker burnout during a persistent crisis: a case-control study.

BACKGROUND: During the immediate outbreak of the COVID-19 pandemic, burnout symptoms increased among healthcare workers. Knowledge is needed on how early symptoms developed during the persistent crisis that followed the first pandemic wave. AIMS: To investigate if high levels of burnout symptoms during the first pandemic wave led to high burnout and depressive symptoms up to a year later, and if participation in psychological support was related to lower levels of symptoms. METHODS: A longitudinal case-control study followed 581 healthcare workers from two Swedish hospitals. Survey data were collected with a baseline in May 2020 and three follow-up assessments until September 2021. The case group was participants reporting high burnout symptoms at baseline. Logistic regression analyses were performed separately at three follow-ups with case-control group assignment as the main predictor and burnout and depression symptoms as outcomes, controlling for frontline work, changes in work tasks and psychological support participation. RESULTS: One out of five healthcare workers reported high burnout symptoms at baseline. The case group was more likely to have high burnout and depressive symptoms at all follow-ups. Participation in psychological support was unrelated to decreased burnout and depressive symptoms at any of the follow-ups. CONCLUSIONS: During a persistent crisis, healthcare organizations should be mindful of psychological reactions among staff and who they place in frontline work early in the crisis. To better prepare for future healthcare crises, preventive measures on burnout are needed, both at workplaces and as part of the curricula in medical and nursing education.

Pain avoidance predicts disability and depressive symptoms three years later in individuals with whiplash complaints.

BACKGROUND: Longstanding symptoms due to whiplash are commonly associated with decreased levels of emotional and physical functioning. To date, there is strong empirical support for the relationship between psychological in/flexibility and pain-related functioning, but the predictive role for future health is largely unknown. Hence, the aim of this study was to investigate if psychological in/flexibility (i.e. avoidance and cognitive fusion) predicted pain disability and depressive symptoms 3 years later in individuals with whiplash complaints. METHODS: Data were collected at baseline and at a 3 year follow-up from 368 members of a national patient organization for people with whiplash-associated disorder. In a series of hierarchical regression analyses, background variables, pain related variables, psychological distress and psychological inflexibility at baseline were evaluated as predictors of levels of pain disability and depressive symptoms at follow-up. RESULTS: Results showed that psychological inflexibility, and more specifically avoidance, was a unique predictor of pain disability and depressive symptoms, also when controlling for background variables, pain related variables and psychological distress. Level of education was also found to predict both pain disability and symptoms of depression. Lastly, pain variability predicted pain disability, and anxiety predicted depressive symptoms. CONCLUSION: Pain avoidance significantly predicted pain disability and depressive symptoms 3 years later. Although tentative, results warrant more studies to further explore the importance of pain avoidance for future health.

A validation of the pain interference index in adults with long-standing pain.

BACKGROUND: Chronic pain is a major health problem and more knowledge is needed regarding the interference of pain on behaviors in different life domains. Clinically useful and statistically sound pain interference measures are highly important. Studies on youths have shown that the Pain Interference Index (PII) is a reliable and valid instrument that is sensitive to change following behavioral treatment. This measure may also have utility for adults, but no study has so far evaluated the statistical properties of the PII for long-standing pain in adults. METHODS: Data were collected from 239 consecutive adults with non-specific chronic pain referred to a tertiary pain clinic. We investigated the factor structure of items using a principal component analysis. Cronbach's alpha was calculated to assess internal consistency. The questionnaire's ability to predict levels of, e.g., disability was analyzed by means of regression analyses. RESULTS: Analyses illustrated the adequacy of a one-factor solution with six items. Cronbach's alpha (0.85) suggested a satisfactory internal consistency among items. The PII explained significant amounts of variance in pain disability, physical, and mental health-related quality of life and depression, suggesting concurrent criteria validity. CONCLUSION: The PII is a brief questionnaire with reliable and valid statistical properties to assess pain interference in adults. Other studies support the reliability and validity of PII for use with youths, and now the PII can be used to analyze the influence of pain on behaviors across age groups. Potentially, the PII can also be used as an outcome measure in clinical trials.

Processes of change in Acceptance and Commitment Therapy and Applied Relaxation for long-standing pain.

BACKGROUND: The utility of cognitive behavioural (CB) interventions for chronic pain has been supported in numerous studies. This includes Acceptance and Commitment Therapy (ACT), which has gained increased empirical support. Previous research suggests that improvements in pain catastrophizing and psychological inflexibility are related to improvements in treatment outcome in this type of treatment. Although a few studies have evaluated processes of change in CB-interventions, there is a particular need for mediation analyses that use multiple assessments to model change in mediators and outcome over time, and that incorporate the specified timeline between mediator and outcome in the data analytic model. METHODS: This study used session-to-session assessments to evaluate if psychological inflexibility, catastrophizing, and pain intensity mediated the effects of treatment on pain interference. Analyses were based on data from a previously conducted randomized controlled trial (n = 60) evaluating the efficacy of ACT and Applied Relaxation (AR). A moderated mediation model based on linear mixed models was used to analyse the data. RESULTS: Neither catastrophizing nor pain intensity mediated changes in pain interference for any of the treatments. In contrast, psychological inflexibility mediated effects on outcome in ACT but not in AR. CONCLUSIONS: Results add to previous findings illustrating the role of psychological inflexibility as a mediator in ACT.

Insomnia in paediatric chronic pain and its impact on depression and functional disability.

BACKGROUND: Children and adolescents attending health care due to chronic pain commonly presents with insomnia. Previous research suggests that problems with sleep are associated with depression and functional disability. However, more research is needed to clarify the relationship between pain, insomnia and disability. OBJECTIVE: This study aims to investigate the frequency, severity and importance of insomnia in paediatric patients with chronic pain and to evaluate the mediating role of insomnia in explaining the relationship between pain and depression as well as between pain and functioning. In addition, to ascertain the adequacy of using a Swedish translation of the Insomnia Severity Index (ISI) with youths, analyses included a statistical evaluation of the instrument. METHOD: Correlational analyses of cross-sectional data from 154 consecutive paediatric patients with chronic pain referred to a tertiary pain clinic. RESULTS: Insomnia explained a significant amount of variance in depression and functional disability when controlling for demographic characteristics and pain. Indirect effects of insomnia were found for both the relationship between pain and depression, and between pain and functional disability. ISI showed satisfactory psychometric properties in this sample, including internal consistency and concurrent criteria validity. CONCLUSIONS: Insomnia is highly important in explaining depression and functional disability in paediatric chronic pain and can be adequately assessed using the ISI.

Acceptance and commitment therapy for fibromyalgia: a randomized controlled trial.

BACKGROUND: Fibromyalgia (FM) is characterized by widespread pain and co-morbid symptoms such as fatigue and depression. For FM, medical treatments alone appear insufficient. Recent meta-analyses point to the utility of cognitive behaviour therapy (CBT), but effects are moderate. Within the continuous development of CBT, the empirical support for acceptance and commitment therapy (ACT) has increased rapidly. ACT focuses on improving functioning by increasing the patient's ability to act in accordance with personal values also in the presence of pain and distress (i.e., psychological flexibility). However, no study has yet explored the utility of ACT in FM. OBJECTIVES: To evaluate the efficacy of ACT for FM and the role of psychological inflexibility as a mediator of improvement. METHODS: In this randomized controlled trial, ACT was evaluated in comparison to a waiting list control condition. Forty women diagnosed with FM participated in the study. Assessments were made pre- and post-treatment and at 3 months of follow-up. The ACT intervention consisted of 12 weekly group sessions. RESULTS: Significant differences in favour of ACT were seen in pain-related functioning, FM impact, mental health-related quality of life, self-efficacy, depression, anxiety and psychological inflexibility. Changes in psychological inflexibility during the course of treatment were found to mediate pre- to follow-up improvements in outcome variables. CONCLUSIONS: The results correspond with previous studies on ACT for chronic pain and suggest the utility of ACT for FM as well as the role of psychological inflexibility as a mediator of improvement.
