Can mindfulness-based interventions improve outcomes in cognitive-behavioural therapy for chronic insomnia disorder in the general population? Systematic review and meta-analysis
(Wiley, 2023) Entrambasaguas, Manuel de; Díaz-Silveira, Cintia; Burgos-Julián, Francisco A.; Santed, Miguel A.
Cognitive-behavioural therapy for insomnia (CBT-I) is the recommended first-line therapy for adults with chronic insomnia disorder (ID), which is characterized by hyperarousal. Mindfulness-based interventions (MBIs) are protocols aimed at stress reduction based on non-judgmental attention control in the present moment. However, MBIs have been increasingly used without a clear scientific basis. The objective of this analysis was to examine if MBIs could be useful as a component of the CBT-I therapeutic system through a systematic review and meta-analysis of randomized controlled trials (RCTs) and non-randomized studies (NRS) searched in PubMed, PsycINFO, Cochrane and WoS. The Insomnia Severity Index (ISI) was the primary outcome, while the Pittsburgh Sleep Quality Index (PSQI) and a composite sleep variable (CSV) were secondary outcomes. Thirteen articles corresponding to nine studies (three pragmatic RCTs, three explanatory RCTs and three NRS) were included. The omnibus test found that MBIs had a small to medium effect size on ISI nearing signification when comparing active control groups in the pretest–posttest period [Δ = 0.44, p = 0.07], a medium, non-significant, effect size on PSQI [Δ = 0.52, p = 0.18], and a significant though small effect size on CSV [Δ = 0.05, p < 0.01]. No heterogeneity was found. The analysis could not demonstrate that MBIs, combined with CBT-I components in some studies, positively affected ID in the general adult population. This was probably due to the lack of pragmatic designs and suitable measuring instruments. Recommendations are made for designing further studies to address these issues.
Effectiveness of mindfulness-based interventions on anxiety for children and adolescents: A systematic review and metaanalysis
(Wiley, 2019-07-09) Ruiz-Íñiguez, Raquel; Santed-Germán, Miguel A.; Burgos-Julián, Francisco A.; Díaz-Silveira, Cintia; Carralero Montero, Ana
Abstract Aim: This paper aims to investigate the extent to which mindfulness-based interventions serve to reduce anxiety in children and adolescents. A heterogeneous sample was used, including clinical and non-clinical population. Methods: A literature search of controlled intervention studies published up to December 31, 2016, was carried out in PubMed, Lilacs, Cochrane, Embase, PsycInfo, Opengrey and Teseo databases. The effect size was calculated by Cohen's d. The Cochran Q statistic and the I2 index were used for the study of heterogeneity. An analysis was conducted using the random effects model. Results: 829 articles were identified, of which 18 were finally selected. Of these, only three had statistically significant effect sizes. The overall combined result obtained was .013, but it did not result statistically significant (CI95% [−.102, .128].) The Q statistic was statistically significant (Q [18] = 28.497, P = . 39) and the I2 index was 40.34%, indicating a moderate heterogeneity. Conclusions: This meta-analysis did not obtain statistically significant results that could provide conclusions. In general, the studies analysed are small, of low power and have a marked heterogeneity, which implies that the findings are provisional and need to be supported by more robust studies. Although it cannot be ruled out that mindfulness-based interventions are not effective in the infant-juvenile population, it is also possible that this effect could not be detected due to the limited number of available studies. Larger investigations are needed, with sufficient statistical power and designs that control the variables potentially moderating, to establish clear conclusions.
Mindfulness-Based Interventions for People with Schizophrenia: A Systematic Review and Meta-Analysis
(MDPI, 2020-06-30) Hodann-Caudevilla, Ricardo M.; Díaz-Silveira, Cintia; Burgos-Julián, Francisco A.; Santed-Germán, Miguel A.
Abstract: (1) Background: There is increasing interest in the practice of mindfulness-based interventions (MBIs) to treat people with schizophrenia, as evidenced by the publication of different randomized controlled trials (RCTs). However, no meta-analysis of RCTs has been carried out to date with the exclusive inclusion of this type of interventions. (2) Objective: To analyze empirical evidence regarding the effectiveness of MBIs for the improvement of clinical parameters associated with schizophrenia. Method: A systematic review and meta-analysis was conducted of RCTs published in the databases PsycINFO, PubMed, WOS, and Cochrane Library. (3) Results: A total of 10 articles (n = 1094) fulfilled the criteria for inclusion in the review. The analysis of these studies suggests that MBIs combined with standard interventions are able to generate significant improvements in a variety of clinical schizophrenia-related parameters, such as the intensity of overall symptomatology (g = 0.72), positive symptoms (g = 0.32), negative symptoms (g = 0.40), functioning level (g = 1.28), and awareness of illness (g = 0.65). (4) Conclusions: There is evidence that supports the effectiveness and safety of MBIs for the treatment of people with schizophrenia. The results obtained by MBIs are comparable to those obtained by cognitive-behavioral therapy for psychosis. However, given the heterogeneity of the applied interventions and the methodological limitations found in the reviewed trials, the results should be interpreted with caution.
