Effects of dyadic interventions on psychological outcomes among cancer patients with non-active treatment: a systematic review and meta-analysis.

OBJECTIVE: Cancer and its treatment can generate substantial psychological distress (depression and anxiety). The objective of this systematic review and meta-analysis is to explore the effectiveness of dyadic interventions on psychological outcomes in cancer patients with non-active treatment and to test subgroup analyses to explore the source of heterogeneity affecting effect sizes. DESIGN: Systematic searching across eight databases identified studies related to dyadic interventions for psychological outcomes of cancer patients published between 2007 and 2022. Rigorous inclusion and exclusion criteria were utilized. Random-effects models were used to compute effect sizes with Hedge's g, forest plot, and Q and I2 statistics to measure heterogeneity. Moderator analyses were examined. RESULTS: Eleven primary studies were identified (938 patients with cancer, 56.14 ± 7.29 years old). Overall, dyadic interventions significantly improved depression (g = .36, 95% confidence interval .026 to .68, I2 = 76%) and anxiety (g = .29, 95% confidence interval 0.14 to .45, I2 = 0%) compared to controls. With subgroup analyses, fidelity of dyadic interventions, number of weeks across intervention, and number of days after intervention measured were moderators affecting effect sizes. CONCLUSION: Dyadic interventions appear to be effective among adults with cancer with non-active treatment. Additional research is needed to explore the efficacy of dyadic interventions among more diverse samples and to examine routes for integrating dyadic interventions into practice. IMPLICATIONS FOR CANCER SURVIVORS: Adult with cancer might participate in the dyadic intervention for improving psychological outcomes.

Efficacy of a Mind Space Application intervention on psychological outcomes in Thai university students with depression: A pilot randomized controlled trial.

OBJECTIVE: This purpose of this study is to evaluate the effects of the Mind Space Application on psychological outcomes among Thai-university students with depression. METHOD: Thai-university students with depression (N = 50) were recruited between November 2021 and January 2022. Participants were randomly assigned to either an 8-week mindfulness-based intervention via the Mind Space Application intervention or a waitlist control group. Stress, anxiety, depression, and mindfulness were assessed at baseline and post-intervention. RESULTS: Post-intervention, compared to waitlist control group, participants using the Mind Space Application reported large effects in the reduction of stress (d = 1.46, p < .001) and depression (d = 1.88, p < .001), small to moderate effects in reduction of anxiety (d = 0.35, p = .35), but no significant. Also, mindfulness scores were significantly higher (d = 1.90, p < .001) compared to the waitlist control group. CONCLUSION: Thai-university students with depression who used the Mind Space Application showed lower stress and depression and higher mindfulness compared to the waitlist group among. Similar applications may be useful as an alternative or combined with other treatments to improve psychological outcomes in other university student populations.

The experience of Thai adolescents with depression: A qualitative study.

AIM: People who have depression experience a maelstrom of emotion as they attempt to understand what is happening to them. While the experience has been quite extensively documented in adults and older individuals, there is a great deal less information available about adolescent depression experiences and reactions. The purpose of this study was to investigate the experiences of Thai-adolescents suffering from depression. DESIGN: Interpretative phenomenological analysis. METHOD: Fourteen adolescents were recruited from a secondary school in Chiangrai province, Thailand. Semi-structured interviews were carried out. Interviews were analysed using interpretative phenomenological analysis. RESULTS: The following four themes were identified: (1) struggling to make sense of their situation, (2) feeling down and withdrawing, (3) contemplating self-harm and (4) therapy as a last choice. The results point to the continuing significance of promoting psychoeducation for Thai-adolescents with depression as well as parents, school nurses and health providers while eliminating stigma.

Effects of mindfulness-based interventions (MBIs) on depression in pregnant women: A systematic review and meta-analysis.

OBJECTIVE: We synthesized the effects of mindfulness-based interventions (MBIs) on depression in pregnant women. METHOD: Ten electronic databases were searched from inception to September 2022. We reviewed studies on outcomes for pregnant women with depression receiving mindfulness-based interventions. We only reviewed studies written in English. A random-effects model was used to compute the effect size. Funnel plot, Q statistics, and I2 were used to test the heterogeneity across studies. We examined moderators to explore sources of heterogeneity. RESULTS: Across 19 included studies (N = 1480), 717 pregnant women participated in mindfulness interventions; 763 served as controls. Mean age ranged from 25.3 to 33.6 years. Overall, mindfulness-based interventions showed reduced depression compared to control groups (g = 0.457, 95%CI 0.254, 0.659, I2 = 68 %). With subgroup analysis, mindfulness-based cognitive therapy had a greater effect on reducing depressive symptoms (g = 1.13) than mindfulness-based stress reduction (g = 0.64) and adapted mindfulness-based interventions (g = 0.31). No quality indicators moderated the ES of mindfulness-based interventions on depression. CONCLUSION: Mindfulness-based interventions significantly improved depression among pregnant women, especially mindfulness-based cognitive therapy (MBCT). Clinicians and health providers should consider using MBIs as alternative complementary treatment for improving and preventing depression in pregnant women.

The Role of the School Nurse in Addressing Climate-Associated Illnesses: Mental Well-being.

Human health is being impacted by anthropogenic (human-made) climate change. This article describes four ways that climate change may affect mental well-being in school-age children. First, natural disasters-such as more frequent and intense tornadoes and flash floods-may have a direct influence on mental well-being by contributing to acute anxiety and distress. Second, indirect effects of severe weather-including changes in social support systems-may affect mental well-being by increasing isolation. Third, children may suffer feelings of anxiety or depression if they perceive a sense of powerlessness to solve the challenges of a changing climate. Finally, school nurses need to be aware of the emergence of correlations-such as data that suggest increases in temperature may influence the use of inpatient mental health services and suicidal ideations-that require further scientific exploration. This article aims to increase school nurses' understanding of how climate changes may impact the mental well-being of school-age children and to provide strategies for creating a safe, healthy learning environment. This article is the fourth in a series aimed at raising awareness among school nurses about climate-associated illnesses and equipping them with the resources they need to protect school-age children's health.

Effects of Mindfulness-Based Interventions on Depression in Patients With Breast Cancer: A Systematic Review and Meta-Analysis.

OBJECTIVE: We examined the effects of Mindfulness-based interventions (MBIs) on depressive symptoms in women with breast cancer and examined the moderating effects of participant characteristics, research methodologies, and features of interventions. METHODS: We systematically searched 12 databases through November 2022 without date restrictions using the following search terms: (mindful* or meditation) AND (cancer OR neoplasm) AND (depress*). Studies included were primary studies evaluating MBIs in women with breast cancer who also had depression. Studies were included if they used a control group and were written in English. We used a random-effects model to compute effect sizes (ESs) using Hedges' g, forest plot, and Q and I2 statistics as measure of heterogeneity. We also requested moderator analyses. RESULTS: We found 19 studies with 2139 participants (49.4 ± 8.3 years old) that met inclusion criteria for this meta-analysis and systematic review. Overall, women in MBI groups demonstrated significantly lower levels of depression (g = 0.48, 95% CI:0.159, 0.792, P < .001) compared to women in control groups. Regarding moderators, providing MBIs with a home assignment component showed a significantly greater effect on decreasing depressive symptoms (g = 1.75) compared to MBIs without a home assignment component (g = 0.20). When researchers used concealed allocation technique, the interventions demonstrated lower effects on depression than when concealed allocation (g = 0.11vs g = 1.33, P ≤ .001) was not reported. Additionally, when researchers reported high rates of sample attrition, they found a lower effect size on depression (ß = -.019, Q = 3.97, P = .046) indicating that attrition moderates the effect. CONCLUSION: MBIs are moderately effective interventions to reduce depressive symptoms among women with breast cancer. Clinicians might consider encouraging MBIs as adjunct/alternative treatments for women with breast cancer to manage symptoms of depression. Interventions that incorporat home assignments for practicing mindfulness are likely to have a greater effect on reducing depressive symptoms. Additionally, methods including concealed allocation and attrition rate were moderators of the effects of MBIs on depression in women with breast cancer.

Effects of online mindfulness-based interventions (MBIs) on anxiety symptoms in adults: a systematic review and meta-analysis.

BACKGROUND: An increasing number of studies have documented the effectiveness on various types of face-to-face and online mindfulness-based interventions (MBIs) in reducing anxiety among general population, but there is a scarcity of systematic reviews evaluating evidence of online MBIs on anxiety in adults. Therefore, we examined the effects of online mindfulness-based interventions (MBIs) on anxiety symptoms in adults and explored the moderating effects of participant, methods, and intervention characteristics. METHODS: We systematically searched nine databases through May 2022 without date restrictions. Inclusion criteria were primary studies evaluating online mindfulness-based interventions with adults with anxiety measured as an outcome, a comparison group, and written in English. We used random-effects model to compute effect sizes (ESs) using Hedges' g, a forest plot, and Q and I2 statistics as measures of heterogeneity; we also examined moderator analyses. RESULTS: Twenty-six primary studies included 3,246 participants (39.9 ± 12.9 years old). Overall, online mindfulness-based interventions showed significantly improved anxiety (g = 0.35, 95%CI 0.09, 0.62, I2 = 92%) compared to controls. With regards to moderators, researchers reported higher attrition, they reported less beneficial effects on anxiety symptoms (ß=-0.001, Qmodel=4.59, p = .032). No other quality indicators moderated the effects of online mindfulness-based interventions on anxiety. CONCLUSION: Online mindfulness-based interventions improved anxiety symptoms in adult population. Thus, it might be used as adjunctive or alternative complementary treatment for adults. However, our findings must be interpreted with caution due to the low and unclear power of the sample in primary studies; hence, high-quality studies are needed to confirm our findings.

The Effects of Dance Interventions on Depression in Older Adults: A Meta-Analysis.

Meta-analyses of the effects of dance on depressive symptoms in older adults have shown contradictory results, but few primary studies were included (5 and 8 studies). We aimed to examine the effects of dance on depressive symptoms in older adults aged 60 years and older and to examine the moderator effects of the source, participants, methods, and intervention characteristics. We included 23 primary studies that compared depressive symptoms across dance and comparison/control groups of older adults (72 ± 6.7 years old) and were written in English (N = 1,398) participants. Dance groups showed significantly less depressive symptoms post-intervention than comparison groups (ES = 0.66, 95% CI [0.42, 0.91], p < .001, I2 = 76.80%). South America and Australia showed the greatest effects. Using quasi-experimental designs showed significant effect sizes compared to using randomized designs. Only one quality indicator, intention-to-treat, influenced effect size. Dance might be used as an alternative treatment to improve depression.

Effects of mindfulness-based interventions on psychological outcomes in college and university students during COVID-19 pandemics: A systematic review and meta-analysis.

OBJECTIVE: We synthesized the effects of mindfulness-based interventions (MBIs) on psychological outcomes in college and university students during the COVID-19 pandemic. METHOD: Ten electronic databases were searched from inception to December 2021. We reviewed studies with college and university students receiving MBIs with psychological outcomes. We only reviewed studies written in English. A random-effects model was used to compute the effect size. RESULTS: Overall, MBIs showed a significantly moderate improvement in anxiety (g = 0.612, 95% CI: 0.288-0.936, I2 = 77%); depression (g = 0.372, 95% CI: 0.032-0.713, I2 = 72%); and mindfulness (g = 0.392, 95% CI:0.102-0.695, I2 = 64%) compared with control groups, while these interventions had a small effect in reducing stress, but not a significant one (g = 0.295, 95% CI: -0.088 to 0.676, I2 = 77%) compared with control groups. CONCLUSION: MBIs significantly improved psychological outcomes among college and university students during the COVID-19 pandemic. Clinicians and health providers should consider using MBIs as alternative complementary treatment for improving and preventing anxiety and depression in college and university students during COVID-19. CLINICAL RELEVANCE: The use of MBIs for college and university students is an effective method to decrease anxiety, depressive symptoms, and increase mindfulness. MBIs would become a very useful means of alternative complementary treatment in mental health and clinical psychiatry.

Effects of Online Mindfulness-Based Interventions on Depressive Symptoms in College and University Students: A Systematic Review and Meta-Analysis.

Introduction: Depression is considered a multiproblematic disorder that leads to impairment in interpersonal, academic, social, and occupational functioning. Untreated depression can lead to suicide, which is the second leading cause of death among adolescents and young adults. Antidepressants and psychotherapy have limited effectiveness and are not available worldwide. Alternative and complementary treatments, such as online mindfulness-based interventions (MBIs), are growing. Objective: We examined the effects of online MBIs on depressive symptoms in college and university students and explored the moderating effects of participant, methods, and intervention characteristics. Methods: We systematically searched nine databases from their inception through August 2022 without date restrictions. We included primary studies evaluating MBIs with college and university students with depression measured as an outcome, a comparison group, that were written in English. We used random-effects model to compute effect sizes (ESs) using Hedges' g, a forest plot, and Q and I2 statistics as measures of heterogeneity; we also examined moderator analyses. Results: Fifteen studies included 1886 participants (22.6 ± 3.2 years old). Overall, online MBIs showed significantly improved depression (g = 0.18, 95% confidence interval 0.02 to 0.34, I2 = 61%) compared with controls. With regard to moderators, when depression was measured further from the end of the intervention, there was less reduction in depressive symptoms (ß = -0.012, Qmodel = 3.81, p = 0.051). Researchers who reported higher attrition reported less beneficial effects on depressive symptoms (ß = -0.013, Qmodel = 9.85, p = 0.001). Researchers who used intention-to-treat reported lower ESs (g = -0.15) compared with not using intention-to-treat (g = 0.32, p < 0.001). No other quality indicators moderated the effects of online MBIs on depression. Conclusions: Online MBIs improved depressive symptoms in college and university students. Thus, it might be used as one treatment in their tool kit for college and university students.

Effects of Transcendental Meditation on Blood Pressure: A Meta-analysis.

BACKGROUND: The World Health Organization estimates that 1.13 billion people worldwide have hypertension. Although pharmaceutical management of blood pressure is available, there are reasons why people prefer not to take medications including costs, adverse effects, and lack of access. Nonpharmacological healthy lifestyle methods are needed. One alternative method is transcendental meditation (TM). OBJECTIVE: The purpose of this study was to quantitatively synthesize the effects of TM on blood pressure. In addition, we examined the moderator effects of participant, methods, and intervention characteristics. METHODS: We searched 19 electronic databases without date restrictions to March 2021 including the gray literature and specific journals for primary studies evaluating TM to reduce blood pressure in adults and written in English. We coded primary studies for 5 categories (source, method, intervention, participant characteristics, and outcomes). RESULTS: Across 18 primary studies (N = 1207), TM mildly improved systolic blood pressure by -3.3 mm Hg (P = .025) and diastolic blood pressure by -1.8 mm Hg (P = .008) compared with comparison groups, but the effects waned after 3 months. Transcendental meditation reduced systolic blood pressure in samples that were 65 years and older significantly more than in samples that were younger than 65 years (-1.44 vs -9.87, P = .021) but showed no differential effect on diastolic blood pressure. CONCLUSIONS: Transcendental meditation mildly reduced blood pressure, but the effect waned after 3 months. Adults older than 65 years benefited more than younger adults. Transcendental meditation might be recommended as one aspect of a healthy lifestyle.

Effects of Psychotherapy on Hope/Hopelessness in Adults with Cancer: a Systematic Review and Meta-analysis.

BACKGROUND: Although psychotherapy is a common treatment for hopelessness and hope, the effectiveness remains controversial. The purpose of this study was to quantitatively synthesize available evidence related to the effect of a broad range of psychotherapy interventions on hope/hopelessness in cancer patients. METHOD: Eight electronic databases were searched for studies with adult cancer patients (mean age ≥ 18 years) receiving psychotherapy interventions with hope/hopelessness measured as outcomes and written in English. We used the random-effects model to compute effect size using Hedges' g and conducted moderator analyses. RESULTS: We found 27 primary studies which included 1,998 participants who were 57.6 ± 8.0 years old across studies. The psychotherapy effect size ranged from - 0.86 to 2.92. Researchers who conducted psychotherapy at hospital/health centers showed higher effects, that is, improved hope scores (g = 0.63), than those who conducted psychotherapy in the community (g = 0.05). When researchers enrolled participants alone, psychotherapy resulted in higher effects (g = 0.62) than when partners/caregivers were involved (g = - 0.04). Researchers who included group discussion showed lower effects (g = 0.36) than without group discussion (g = 1.10). Researchers who examined fidelity found lower effects (g = 0.16) than researchers who did not examine fidelity (g = 0.66). Interestingly, researchers who studied people with breast cancer showed higher effects (g = 0.96) than those who studied people with other types of cancer (g = 0.26). Researchers who included higher percentages of women showed greater effects (slope = 0.008, Qmodel = 3.99, p = 0.046). Finally, the greater the time span between psychotherapy and the measurement of hope, the lower the psychotherapy effects (slope = - 0.002, Qmodel = 4.25, p = 0.039). CONCLUSION: Psychotherapy had a solid moderate effect on reducing hopelessness and improving hope in cancer patients compared to controls.

Effects of Mindfulness Meditation Intervention on Depressive Symptoms in Emerging Adults: A Systematic Review and Meta-Analysis.

Introduction: Depression in emerging adults (20-29 years of age), a transition from adolescence to adulthood, is a mental health problem globally. Antidepressants and psychotherapy have limited effectiveness and might not be available worldwide. Alternative and complementary treatments, such as mindfulness meditation, are growing. Objective: We examined the effects of mindfulness interventions on depression in emerging adults and explored the moderating effects of participants, methods, and intervention characteristics. Design: Systematic review and meta-analysis. Subjects: Emerging adults. Interventions: Mindfulness meditation interventions versus control groups. Outcomes measures: depressive symptoms. Results: Forty-five studies resulted in 49 comparisons, including 3479 participants (23.0-2.7 years old); 1826 participants practiced mindfulness and 1653 served as controls. Overall, mindfulness interventions showed significant reduction in depression compared with controls (g = 0.44, 95% confidence interval: 0.33-0.55). Mindfulness interventions conducted in Asian countries had a greater decrease in depression (g = 0.69) than studies conducted in North America (g = 0.44) or Europe (g = 0.23). Mindfulness interventions showed greater reductions in depression in studies with higher proportion of females (Slope = 0.010, τ2 = 0.07, Qbetween = 7.10, p = 0.008). Mindfulness interventions conducted in emerging adults with depressive disorders reduced depression more (g = 1.12) than in emerging adults without (g = 0.40). Providing mindfulness intervention in a group setting had a greater reduction of depression (g = 0.54) than on an individual basis (g = 0.30). More minutes of unstructured mindfulness practice per session showed a greater reduction in depressive symptoms (Slope = 0.016, Qbetween = 1.34, p = 0.035). Using intention-to-treat analyses showed a lower ES (g = 0.14) than not using it (g = 0.55). Other quality indicators were not significant moderators. Primary researchers did not report the adverse effects of mindfulness interventions. Conclusion: Mindfulness interventions somewhat improved depression in emerging adults. Because primary researchers did not report the adverse effects, mindfulness interventions should be used with caution. Future researchers might study the adverse effects of mindfulness interventions as well as the long-term effects.

Effects of exercise on depressive symptoms among nursing home residents: a meta-analysis.

OBJECTIVE: We examined the effects of exercise on depression in older adults living in nursing homes and explored the moderator effects of participants, methods, and intervention characteristics. METHODS: We searched 8 databases from inception to January 2020 without date restrictions. We retrieved primary studies measuring exercise with 60-year-olds with depression that were written in English. Two researchers independently coded each primary study and compared codes for discrepancies. They consulted a third researcher to come to consensus. We used random-effects model to compute effect sizes using Hedges' g, a forest plot, and Q and I2 statistics as measures of heterogeneity. We also examined moderator analyses. RESULTS: Twenty-one studies included 2,594 participants (81.8 ± 4.8 years old). Overall, exercise showed a small improvement in depression compared to controls (ES=.25; 95%CI 0.11, 0.38; p=.000). Interestingly, interventionists by physiotherapists had a smaller effect on depressive symptoms (.04) than other health interventionists (.37). As people aged, exercise was less effective in reducing depression (slope=-.03, Qmodel=5.03, p=.025). Researchers who included a higher percentage of women in exercise showed less improvement of depression (slope=-.01, Qmodel=8.60, p=.003). Also, when researchers used depression scales with higher reliability values, they measured higher levels of depression (slope = 5.48, Qmodel=5.60, p=.018). No other quality indicators moderated the effects of exercise on depression. CONCLUSION: Exercise significantly improved depressive symptoms among older adults in nursing homes. Exercise might be used as adjunct/alternative complementary treatment for improving depressive symptoms in older adults in nursing homes.

Effects of Mindfulness-Based Interventions on Depressive Symptoms and Alcohol Craving in Individuals With Comorbid Alcohol Use Disorder and Depression: A Systematic Review.

The co-occurrence of alcohol use disorder (AUD) and depression is associated with a seven-fold increased risk of suicide. The purpose of the current systematic review is to synthesize the evidence of the effectiveness of mindfulness-based interventions (MBIs) on depression and alcohol craving in patients with comorbid AUD and depression. Electronic databases were searched using a combination of key words. Seven studies, investigating a total of 349 participants, were included. MBIs improved depression and alcohol craving among individuals with comorbid AUD and depression. Health care professionals can use MBI as adjunctive treatment for decreasing depression and alcohol craving. Future research is needed to explore how MBIs can be tailored to specific cultures and to document the longitudinal effectiveness of treatment. [Journal of Psychosocial Nursing and Mental Health Services, 59(12), 41-47.].

Effects of mindfulness meditation interventions on depression in older adults: A meta-analysis.

OBJECTIVE: We examined the effects of MMIs on depression in older adults and explored the moderating effects of participant, methods, and intervention characteristics. METHODS: We systematically searched 15 databases through June 2019 without date restrictions using the following search terms: (mindful* OR meditat*) AND depress* AND (older adult* OR elder OR aging OR senior OR geriatric*). Inclusion criteria were primary studies evaluating MMIs with adults ≥65 years old with depression measured as an outcome, a control group, and written in English. Two researchers independently coded each study and compared for discrepancies and consulted a third researcher in cases of disagreement. We used random-effects model to compute effect sizes (ESs) using Hedges' g, a forest plot, and Q and I2 statistics as measures of heterogeneity; we also examined moderator analyses. RESULTS: Nineteen studies included 1,076 participants (71.8 ± 5.2 years old). Overall, MMIs showed significantly improved depression (ES=.65, 95%CI 0.35, 0.94) compared to controls. With regards to moderators, Asians had a greater improvement in depression (1.28) than Europeans (.59) and North Americans (.32). Less than 5 weeks of MMIs showed greater improvement in depression (1.47) than longer periods (.55). MMIs with guided meditation reduced depression (.91) more than MMIs without (.42). Only one quality indicator, a priori power analysis, showed greater effects on depression (g = 1.0) than no power analysis (g=.35). CONCLUSION: MMIs improved depressive symptoms in older adults. MMIs might be used as adjunctive or alternative to conventional treatment for depressed older adults.

Effects of mindfulness interventions on depressive symptoms in adolescents: A meta-analysis.

BACKGROUND: Depression among adolescents is rising globally and is the leading cause of illness and disability among adolescents. While antidepressants and psychotherapy are effective, only about 40% of depressed adolescents receive treatments due to lack of professionals and barriers such as cost and personal obstacles including stigma, lack of motivation, and negative perceptions of treatment. Use of alternative and complementary treatments for depression is growing. One such treatment is mindfulness meditation. OBJECTIVE: We examined the effects of mindfulness interventions on depression among adolescents and explored the moderator effects of participants, methods, and intervention characteristics. METHODS: We searched 17 databases from their inception to April 2019 to identify studies written in English. Search terms included depress* AND mindful* OR meditat* AND adolescen* OR student*; 29 studies met inclusion criteria. Two researchers independently coded data from all primary studies. Discrepancies were discussed with a third researcher to reach consensus. Using the random effects model, we computed the effect sizes (ESs) of mindfulness interventions on depression using standardized mean differences (Hedge's g) with 95% confidence intervals (CI). Funnel plot, Q statistics, and I2 were used to test the heterogeneity across studies. We examined moderators to explore sources of heterogeneity. RESULTS: Across 29 studies (N=3688), 1839 adolescents participated in mindfulness interventions; 1849 served as controls. Mean ages ranged from 10.2 to 19.5 years. Mindfulness groups showed reduced depression compared to control groups (g=.14, 95%CI[.01-.28], p<.042). Funded studies showed greater improvement in depression (g=.34, 95%CI[.09-.58], p<.008) compared to unfunded (g=.05, 95%CI[-.12-.22], p<.554). Interestingly, while only two research teams studied mindfulness-based cognitive therapy, they showed trends toward improvement (p=0.09) in depression (g=.76, 95%CI[.18-1.34], p<.010, s=2) compared to adapted mindfulness interventions (g=.13, 95%CI[-.04-.30], p<.140, s=16) or mindfulness-based stress reduction (g=.07, 95%CI[-.16-.29], p<.559, s=11). Mindfulness interventions with individual counseling tended (p=0.09) to improve depression (g=.46, 95%CI[.07-.85], p<.021, s=3) more than without (g=.10, 95%CI[-.04-.24], p<.168, s=26). Depression improved more when follow-up measures occurred further from the intervention (Slope=.002, τ2=.74, Qbetween=4.10, p=.043, s=29). No quality indicators moderated the ES of mindfulness interventions on depression. CONCLUSION: Mindfulness interventions are mildly effective interventions to reduce depressive symptoms among adolescents. Clinicians trained in mindfulness interventions might encourage mindfulness meditation as adjunctive/alternative treatment for adolescents with mild or moderate depressive symptoms as well as for at-risk adolescents to prevent depression. Funding, type of mindfulness interventions, individual counseling, and time to follow up were moderators of the effects of mindfulness interventions on depression in adolescents.

Development of the Preceptor Self-Assessment Tool and Use of the Content Validity Index.

BACKGROUND: Competency of staff nurse preceptors is an essential factor that determines the success of preceptorship experiences. Competency assessment is complex, and no self-assessment tool exists. METHOD: This article describes phase two of the development of the Preceptor Self-Assessment Tool (PSAT). A content validity index (CVI) survey was completed by 11 subject matter experts to determine relevance of items on the PSAT. RESULTS: The Scale-Level CVI (S-CVI) for the instrument was 0.91, and the items CVI ranged from 0.45 to 1.0; most were above 0.78. One item was dropped and three were collapsed, leaving the final number of items at 64. CONCLUSION: The items on the PSAT have undergone content validity and have been found to be highly relevant. Pilot testing in a large sample of preceptors is warranted to further refine the items on the tool. [J Contin Educ Nurs. 2020;51(10):469-476.].
