•This is the first systematic review and meta-analysis based on longitudinal studies analysing mental disorders and psychiatric comorbidity on suicidal behaviour among young people.•Mental disorders ...increase the risk for suicide attempts in young people.•In particular affective disorders predicted suicide attempts in young people.•Mental disorders and comorbidity are strong predictors of suicide behavior.
Suicide is the second leading cause of death for young people. Objective: To assess mental disorders as risk factors for suicidal behaviour among adolescents and young adults including population-based longitudinal studies.
We conducted a systematic literature review. Bibliographic searches undertaken in five international databases and grey literature sources until January 2017 yielded a total of 26,883 potential papers. 1701 full-text articles were assessed for eligibility of which 1677 were excluded because they did not meet our eligibility criteria. Separate meta-analyses were conducted for each outcome (suicide death and suicide attempts). Odds ratio (OR) and 95% confidence intervals (95%CI) and beta coefficients and standard errors were calculated.
24 studies were finally included involving 25,354 participants (12–26 years). The presence of any mental disorder was associated with higher risk of suicide death (OR = 10.83, 95%CI = 4.69–25.00) and suicide attempt (OR = 3.56; 95%CI 2.24–5.67). When considering suicidal attempt as the outcome, only affective disorders (OR = 1.54; 95%CI = 1.21–1.96) were significant. Finally, the results revealed that psychiatric comorbidity was a primary risk factor for suicide attempts.
Data were obtained from studies with heterogeneous diagnostic assessments of mental disorders. Nine case-control studies were included and some data were collected in students, not in general population.
Mental disorders and comorbidity are strong predictors of suicide behaviour in young people. Detection and management of the affective disorders as well as their psychiatric comorbidity could be a crucial strategy to prevent suicidality in this age group.
Objectives
To assess the association between gender and suicide attempt/death and identify gender-specific risk/protective factors in adolescents/young adults.
Methods
Systematic review (5 databases ...until January 2017). Population-based longitudinal studies considering non-clinical populations, aged 12–26 years, assessing associations between gender and suicide attempts/death, or evaluating their gender risk/protective factors, were included. Random effect meta-analyses were performed.
Results
Sixty-seven studies were included. Females presented higher risk of suicide attempt (OR 1.96, 95% CI 1.54–2.50), and males for suicide death (HR 2.50, 95% CI 1.8–3.6). Common risk factors of suicidal behaviors for both genders are previous mental or substance abuse disorder and exposure to interpersonal violence. Female-specific risk factors for suicide attempts are eating disorder, posttraumatic stress disorder, bipolar disorder, being victim of dating violence, depressive symptoms, interpersonal problems and previous abortion. Male-specific risk factors for suicide attempt are disruptive behavior/conduct problems, hopelessness, parental separation/divorce, friend’s suicidal behavior, and access to means. Male-specific risk factors for suicide death are drug abuse, externalizing disorders, and access to means. For females, no risk factors for suicide death were studied.
Conclusions
More evidence about female-specific risk/protective factors of suicide death, for adolescent/young adults, is needed.
•This research update effectiveness data to telephone-delivered psychotherapy.•It is the first that determine adherence to telephone-administered psychotherapy.•Telephone-delivered psychotherapy ...shows beneficial effects on depression compared to control conditions.•There is no evidence that it is less effective compared to active comparators.•Telephone-delivered psychotherapy shows an adequate treatment adherence.
The aim of this systematic review was to evaluate the effectiveness of telephone-administered psychotherapy for depression in adults when compared to control conditions or other active treatments, and to determine adherence to telephone-administered psychotherapy.
A bibliographic search was conducted in MEDLINE, Embase, PsycINFO, the Cochrane library, and a number of sources of grey literature. We included randomised controlled trials (RCTs) examining the impact of telephone-administered psychotherapy on depressive symptomatology. Two reviewers independently screened citations, extracted the relevant data, and assessed risk of bias using Cochrane tools. Random effects meta-analyses were used to determine the average effect of the interventions on depressive symptomatology: main analysis including randomised trials only, and several exploratory subgroup and sensitivity analyses.
We identified ten trials. Telephone-administered psychotherapy showed beneficial effects on depression severity when compared to control conditions ((standardized mean difference SMD= −0.85 (95% CI −1.56 to −0.15)). When compared to active comparators, the meta-analysis showed a non-significant small effect size (SMD= −0.18 (95% CI −0.45 to 0.09)), in favour of telephone-administered psychotherapy. Total weighted mean adherence was 73%.
Some of the included studies presented a small sample size. Due to variations in time points follow-ups among the studies, it was not possible to determine long term post intervention effects.
Available evidence suggests that telephone-delivered psychotherapy may be an effective strategy to reduce depression symptoms when compared to control conditions, and shows an adequate treatment adherence. Future research is needed to determine its cost-effectiveness and long-term effects.
The present study examined the effects of mindfulness on depression and anxiety, both direct and indirect through the mediation of four mechanisms of emotional regulation: worry, rumination, ...reappraisal and suppression. Path analysis was applied to data collected from an international and non-clinical sample of 1151 adults, including both meditators and non-meditators, who completed an online questionnaire battery. Our results show that mindfulness are related to lower levels of depression and anxiety both directly and indirectly. Suppression, reappraisal, worry and rumination all acted as significant mediators of the relationship between mindfulness and depression. A similar picture emerged for the relationship between mindfulness and anxiety, with the difference that suppression was not a mediator. Our data also revealed that the estimated number of hours of mindfulness meditation practice did not affect depression or anxiety directly but did reduce these indirectly by increasing mindfulness. Worry and rumination proved to be the most potent mediating variables. Altogether, our results confirm that emotional regulation plays a significant mediating role between mindfulness and symptoms of depression and anxiety in the general population and suggest that meditation focusing on reducing worry and rumination may be especially useful in reducing the risk of developing clinical depression.
To assess sociodemographic, clinical and treatment factors as well as depression outcome in a large representative clinical sample of psychiatric depressive outpatients and to determine if ...melancholic and atypical depression can be differentiated from residual non-melancholic depressive conditions.
A prospective, naturalistic, multicentre, nationwide epidemiological study of 1455 depressive outpatients was undertaken. Severity of depressive symptoms was assessed by the Hamilton Depression Rating Scale (HDRS) and the Self Rated Inventory of Depressive Symptomatology (IDS-SR(30)). IDS-SR(30) defines melancholic and atypical depression according to DSM-IV criteria. Assessments were carried out after 6-8 weeks of antidepressant treatment and after 14-20 weeks of continuation treatment.
Melancholic patients (16.2%) were more severely depressed, had more depressive episodes and shorter episode duration than atypical (24.7%) and non-melancholic patients. Atypical depressive patients showed higher rates of co-morbid anxiety disorders and substance abuse. Melancholic patients showed lower rates of remission.
Our study supports a different clinical pattern and treatment outcome for melancholic and atypical depression subtypes.
The aim of this systematic review was to determine the adherence to lifestyle interventions for adults with depression and to estimate the dropout rates in trials examining the impact of these ...interventions. A bibliographic search was conducted in PubMed, Embase, PsycINFO, the Cochrane library, and several sources of grey literature. We included randomised controlled trials examining the impact of multiple lifestyle interventions on depressive symptomatology in adults when compared to control or other active treatments. Two reviewers independently screened citations, extracted the relevant data, and assessed the risk of bias using Cochrane tools. A random effects meta-analysis of proportions was used to summarise the proportion of participants who completed the intervention and to determine the proportion of dropouts at post-treatment assessment. Multiple subgroup analyses were also carried out. We identified six trials. The meta-analysis of proportions showed that 53% (95%CI 49% to 58%) of the participants assigned to the intervention group fully adhered to the intervention program. The weighted mean proportion of completed intervention sessions was 66%. The pooled trial dropout rate was 22% (95%CI 20% to 24%). Around half of adults with depression adhere to lifestyle interventions. Future research is needed to develop interventions to support adherence to lifestyle interventions in depressive patients.
One-quarter of the world's population will suffer from depression symptoms at some point in their lives. Mental health services in developed countries are overburdened. Therefore, cost-effective ...interventions that provide mental health care solutions such as Web-based psychotherapy programs have been proposed.
The intent of the study was to identify expectations regarding Web-based psychotherapy for the treatment of depression in primary care among patients and health professionals that might facilitate or hinder its effects.
The expectations of untreated patients and health professionals were examined by means of interviews and focus groups. There were 43 participants (20 patients with mild and moderate levels of depression, 11 primary care physicians, and 12 managers; 22 of them for interviews and 21 for groups). A thematic content analysis from the grounded theory for interviews, and an analysis of the discursive positions of participants based on the sociological model for groups were performed. Interpretations were achieved by agreement between three independent analysts.
All participants showed a good general acceptance of Web-based psychotherapy, appreciating possible advantages and improvements. Patients, physicians, and managers shared the same conceptualization of their expectations, although highlighting different aspects. Patients focused on the need for individualized and personalized interaction, while professionals highlighted the need for the standardization of the program. Physicians were concerned with extra workload, while managers were worried about optimizing cost-effectiveness.
Expectations of the different participants can conflict with each other. Finding a balanced position among them is needed if we are to harmoniously implement effective Web-based interventions for depression in routine clinical practice.
Benzodiazepines are extensively used in primary care, but their long-term use is associated with adverse health outcomes and dependence.
To analyse the efficacy of two structured interventions in ...primary care to enable patients to discontinue long-term benzodiazepine use.
A multicentre three-arm cluster randomised controlled trial was conducted, with randomisation at general practitioner level (trial registration ISRCTN13024375). A total of 532 patients taking benzodiazepines for at least 6 months participated. After all patients were included, general practitioners were randomly allocated (1:1:1) to usual care, a structured intervention with follow-up visits (SIF) or a structured intervention with written instructions (SIW). The primary end-point was the last month self-declared benzodiazepine discontinuation confirmed by prescription claims at 12 months.
At 12 months, 76 of 168 (45%) patients in the SIW group and 86 of 191 (45%) in the SIF group had discontinued benzodiazepine use compared with 26 of 173 (15%) in the control group. After adjusting by cluster, the relative risks for benzodiazepine discontinuation were 3.01 (95% CI 2.03-4.46, P<0.0001) in the SIW and 3.00 (95% CI 2.04-4.40, P<0.0001) in the SIF group. The most frequently reported withdrawal symptoms were insomnia, anxiety and irritability.
Both interventions led to significant reductions in long-term benzodiazepine use in patients without severe comorbidity. A structured intervention with a written individualised stepped-dose reduction is less time-consuming and as effective in primary care as a more complex intervention involving follow-up visits.
Depression is one of the most common mental disorders and will become one of the leading causes of disability in the world. Internet-based CBT programs for depression have been classified as "well ...established" following the American Psychological Association criteria for empirically supported treatments. The aim of this study is to analyze the cost effectiveness at 12-month follow-up of the Internet-based CBT program "Smiling is fun" with (LITG) and without psychotherapist support (TSG) compared to usual care. The perspective used in our analysis is societal. A sample of 296 depressed patients (mean age of 43.04 years; 76% female; BDI-II mean score = 22.37) from primary care services in four Spanish regions were randomized in the RCT. The complete case and intention-to-treat (ITT) perspectives were used for the analyses. The results demonstrated that both Internet-based CBT interventions exhibited cost utility and cost effectiveness compared with a control group. The complete case analyses revealed an incremental cost-effectiveness ratio (ICER) of €-169.50 and an incremental cost-utility ratio (ICUR) of €-11389.66 for the TSG group and an ICER of €-104.63 and an ICUR of €-6380.86 for the LITG group. The ITT analyses found an ICER of €-98.37 and an ICUR of €-5160.40 for the TSG group and an ICER of €-9.91 and an ICUR of €496.72 for the LITG group. In summary, the results of this study indicate that the two Internet-based CBT interventions are appropriate from both economic and clinical perspectives for depressed patients in the Spanish primary care system. These interventions not only help patients to improve clinically but also generate societal savings.
