Introduction
Suicide is a major health problem, and depression is a major psychiatric cause of suicide. Suicide is influenced by the multifactorial interaction of many risk factors. Therefore, epigenetic research may lead to understandings that are applicable to suicide. This study investigated whether epigenetic changes are associated with suicidal behavior and evaluated the treatment outcome of suicidal ideation in depressive patients.Methods
In 108 patients with major depression, the promoter methylation of the gene encoding brain-derived neurotrophic factor (BDNF) was measured. Sociodemographic and clinical characteristics including a history of previous depressive episodes, age at onset, duration of illnesses, family history of depression, and number of stressful life events as well as subjective perception of stress and assessment scales for depression (HAMD), anxiety (HAMA), function (SOFAS), disability (WHODAS-12), and quality of life (WHOQOL-BREF) were evaluated at baseline. Suicidal behavior was ascertained using a semistructured clinical interview with questions about severity and intent. Beck Scale for Suicide Ideation (BSS) was administered during 12 weeks of treatment with antidepressants.Results
A higher BDNF promoter methylation status was significantly associated with a previous suicidal attempt history, suicidal ideation during treatment, and suicidal ideation at last evaluation as well as with higher BSS scores and poor treatment outcomes for suicidal ideation.Limitations
Methylation status was investigated with limited area of the BDNF gene and sample size was relatively small.Conclusions
BDNF methylation status could be a proxy marker for previous suicidal attempts and a clinical biomarker for poor treatment outcomes of suicidal ideation in depression. 相似文献2.
Background
Data from large nationally representative samples are needed to provide the empirical foundation to inform health policies for the prevention of suicide risk and risk behaviors in men and women.Methods
Data were extracted from the 2010 Health Barometer, a large telephone survey on a representative sample of the general population aged 15–85 years living in France (n=27,653), carried out by the National Institute for Health Promotion and Health Education. Data were collected between October 2009 and July 2010. A computer-assisted telephone interview (CATI) system was used.Results
Overall, 3.9% of respondents aged 15 to 85 reported past year suicidal ideation, and 0.5% reported a suicide attempt in that time period. Increased rates of risky sexual behavior are associated with ideation and attempt in both men and women, after controlling for sociodemographic variables. Homosexuality or bisexuality are associated with suicidal ideation for both men and women, but not with attempts. Substance misuse, physical and sexual assaults are strongly associated with suicidal symptoms for both men and women. Early first experiences with sex, tobacco, and alcohol are associated with suicidal symptoms though somewhat differentially for men and women.Limitations
Cross-sectional survey.Conclusion
The findings underscore associations between suicidal thoughts and behaviors and risk behaviors such as unprotected sex and substance use in men and women throughout the lifespan. These associations highlight the need for preventive strategies such as screening for risk behaviors in order to identify men and women particularly at risk for suicidal behavior. 相似文献3.
Suicidal behaviors in elderly Koreans: One-month-point prevalence and factors related to suicidality
Jae Young Park Ji Won Han Hyeon Jeong Hyun-Ghang Jeong Tae Hui Kim In-Young Yoon Ki Woong Kim 《Journal of affective disorders》2013
Background
Suicide prevention in the elderly is a major public health priority worldwide and in Korea in particular. We investigated the one-month-point prevalence and factors related to suicidality for suicidal behaviors in elderly Koreans.Methods
A simple random sample (N=1588) was drawn from the residential roster of 14,051 Koreans aged 60 years or older who were residents of Osan in February 2010. All subjects were invited to participate in the survey through door-to-door home visits, and the response rate was 59.8%.Results
The age- and gender-standardized prevalence rates of lifetime suicide attempts, current suicidal ideation without a plan or attempt, and current suicidal ideation with a plan or attempt were estimated at 9.2%, 19.6%, and 2.24%. The prevalence of suicidal ideation without a plan or attempt was higher in women and less-educated individuals and increased with advancing age, whereas the prevalence of suicidal ideation with a plan or attempt was higher in more-educated individuals, was not differentiated by gender, increased until age 70, and then decreased thereafter. The factors related to suicidal ideation differed by the presence of a suicide plan or attempt.Conclusions
Depressive elders in their 70s who have recently developed suicidal ideation would be a prime target for suicide intervention programs.Limitations
The sample was regional, although the suicide rate in Osan was comparable to the average suicide rate in Korea. 相似文献4.

Background
Depression is a major risk factor for suicide, but few studies have examined psychosocial risk factors for suicide in clinical patients with depression. The purpose of this study was to investigate psychosocial factors which could be associated with suicidal ideation in clinical patients with depression including: sick-leave, help-seeking behavior, and reluctance to admit mental health problems.Methods
A multi-center cross-sectional survey using self-report questionnaire was conducted at 54 outpatient psychiatric clinics in Tokyo in 2012. Adult outpatients who were diagnosed by psychiatrists as mood disorders (F30–F39) in the International Classification of Diseases-10 (ICD-10) were included in the study. Those who met the criteria for current hypomanic or manic episode were excluded from the study.Results
A total of 189 patients with depression participated in the survey. Multivariable logistic regression analysis showed that taking sick-leave and having sought help from family were associated with decreased odds of current suicidal ideation. Moderate or more severe depression was associated with increased odds of suicidal ideation, and reluctance to admit own mental health problem tended to increase odds of suicidal ideation.Limitations
Living status and suicidal ideation before consultation with psychiatrist were not investigated. Severity of suicidal ideation and comorbid psychiatric disorders were not assessed.Conclusions
Importance of treatment of more severe depression for suicide prevention was confirmed. Industrial health staffs should consider the possibility of positive effect of taking sick-leave when they see employees with depression. Promoting help-seeking for family and reducing stigma of mental illness may be effective for suicide prevention. 相似文献5.
Background
This is a quantitative review of existing studies of transdermal selegiline for major depressive disorder.Methods
Data for dichotomous outcomes were extracted from the five 6–8 week studies of transdermal selegiline. Number needed to treat (NNT) vs. placebo was calculated for response and remission using standard definitions. Number needed to harm (NNH) vs. placebo for commonly encountered adverse events (AEs), AEs associated with sexual function, incidence of weight gain ≥5% from baseline, and discontinuation due to an AE, were also calculated. Data was pooled as appropriate and likelihood to be helped or harmed (LHH) ratios contrasting remission with selected tolerability outcomes were determined.Results
When pooling together the two pivotal trials as identified in product labeling, NNT for response was 11 (95% CI 6–109) and for remission, 9 (95% CI 6–28). Pooling all trials, NNH for application site reaction was 7 (95% CI 6–10) and for insomnia, 19 (95% CI 12–41). There were no clinically relevant differences from placebo regarding weight gain or impairment in sexual functioning. NNH for discontinuation due to an AE was 32 (95% CI 19–132). LHH for remission vs. discontinuation from treatment due to an AE was 3.6.Limitations
The studies included were not identical in design. The studies were registrational in nature and thus not necessarily generalizable.Conclusions
NNT for transdermal selegiline for efficacy is similar to that for other antidepressant regimens for which similar analyses have been published. There appear to be no clinically relevant effects of selegiline on weight or sexual functioning. 相似文献6.

Background
Depressive disorders are disabling conditions striking at all ages. In adults, subthreshold depression (SD) is viewed as being on a continuum with major depressive disorder (MDD). Whether this holds for children and adolescents, is still unclear. We performed the first systematic review of SD in subjects below 18 years, in order to explore if childhood SD and MDD share causal pathways, phenomenology and outcomes, supporting a dimensional view.Methods
A critical systematic review in accordance with preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. A review protocol was developed a priori, and all reports were assessed by two reviewers.Results
The literature search generated 941 eligible references and 24 studies were included. Although diagnostic criteria for SD showed great variability, similarities for SD and MDD were striking. Both were common conditions with similar risk factor patterns. Clinical characteristics in both groups were depressed mood, suicidal ideation and high comorbidity. Outcomes were almost equally poor, with increased psychiatric morbidity and health service use. SD intervention studies showed promising results.Limitations
Reports with data on SD not reported in keywords or abstract may have been missed by the search strategy.Conclusion
A dimensional view of depressive disorders is also supported in children and adolescents, suggesting SD to be a precursor to MDD. Although SD is a somewhat milder condition than MDD, it has severe outcomes with psychopathology and impairment. There is a need of identifying cost-efficient and longlasting interventions in order to prevent development of early SD into MDD 相似文献7.
Background
Suicidal ideation has been identified as both a common antecedent and a significant risk factor for suicide attempt and completed suicide. However, little is known about the incidence and persistence of suicidal ideation in the general population and the associated risk factors.Methods
A 12-month follow-up survey investigated 997 of the respondents who participated in the baseline territory-wide survey of adult population in Hong Kong. A set of baseline psychological factors was considered as predictors of first onset and persistence of suicidal ideation.Results
Twelve-month incidence (1.9%) and persistence (6.2%) rates were estimated. Respondents with anxiety and lack of reasons for living were more likely to report a development of suicidal thoughts in the follow-up assessment, while respondents with higher level of average life distress and lower level of hope were at increased risk of continuing to have suicidal thoughts. Depression was found to partially mediate the effect of average life distress on persistent suicidality.Limitations
Retention rate of the follow-up sample was about 50% only. Assessments of suicidal ideation were based on retrospective reports.Conclusions
Psychological factors differentially predict first onset and persistence of suicidal ideation. It is of clinical value that depression partially mediated the effect of life distress on persistence of suicidality. 相似文献8.
Background
Suicide is a common problem worldwide and the magnitude is high especially in countries where mental illnesses are prevalent and psychiatric services are poor.Objective
To determine the prevalence of suicidal ideation and attempts among patients who attended the Psychiatry clinic of Gondar University Hospital.Methods
A cross sectional study was conducted from March–December 2006 involving a total of 474 patients. Data was collected using a pre tested structured questionnaire containing basic socio-demographic variables, psychiatric diagnosis, suicidal ideation, suicidal attempt, the methods of suicide attempt and ways of survival from the attempted suicide. It was administered by psychiatry nurses working in the clinic. The data was analyzed anonymously using SPSS software.Results
The commonest mental illness was Major Depressive Disorder (51.3%) followed by Psychosis (38%). Ninety one (19.2 %) patients attempted suicide at least once after the onset of the current mental illness and 307(64.8%) have suicidal ideation. The common method of suicidal attempt was hanging (45.1%) and 69.2% were at home. An association was found between suicidal ideation and attempt (OR=33.7; CI=8.2–138.8, p-value <0.01).Conclusion
Suicidal ideation was common in psychiatric patients. It was also associated with suicidal attempt. 相似文献9.

Background
We investigated effects of current age and age at onset on symptomatology of depression with reference to proposed revisions in DSM-5.Methods
The study entailed medical records of 326 inpatients diagnosed with major depressive disorder, including 520 depressive episodes, with 113 first episodes lifetime. Subjects were divided into three groups: young-adults, middle-aged adults and older adults.Results
In young-adults, active suicidal ideation, lifetime suicidal attempts, irritability, anhedonia and persistent depressive symptoms between the episodes were more frequent than in the other groups. Among older adults, depression was associated with insomnia, hypochondriasis, somatization, decreased appetite, weight loss, memory impairment and decreased activity. The older age was not associated with higher number of previous episodes of depression, bigger severity or duration of a single episode or a different degree of remission. Early-onset depression was associated with more suicidal attempts.Limitations
The study was retrospective and the sample may be treated only as representative for hospitalized depressed patients.Conclusions
Age and age at onset are important factors influencing the course and symptomatology of a depressive episode. Depressive episodes with anxiety and with suicide risk severity are important specifiers that vary with the age at onset and/or age of the patient and should be considered for inclusion in the DSM-5 revision. 相似文献10.
Background
Low socio-economic status (SES) is an established risk factor of suicidal behaviours, but it is unknown to what extent its association is direct, indirect or confounded, given its strong association to mental health. We aimed to (I) estimate the prevalence of suicidal behaviours; (II) describe relevant risk factors; and (III) investigate direct and indirect effects of SES on suicidal behaviours.Methods
We used cross-sectional community survey data of adults from randomly selected South East London households (SELCoH). Suicidal outcome measures replicated the 2007 Adult Psychiatric Morbidity Survey in England (APMS). Lifetime prevalence was described by socio-demographics, SES, mental health indicators, and life events. Structured symptom screens and a drug use questionnaire measured mental health. Structural equation models estimated direct and indirect effects of a latent SES variable on suicidal ideation and suicide attempts, adjusting for covariates.Results
20.5% (95% CI: 18.4–22.7) reported suicidal ideation and 8.1% (95% CI: 6.8–9.7) reported suicide attempts (higher than APMS estimates: 13.7%, 4.8%, respectively). Unadjusted risk factors included poor mental health, low SES, and non-married/non-cohabitating relationship status. Black African ethnicity was protective, and women reported more suicide attempts. SES was directly associated to suicide attempts, but not suicidal ideation. SES had indirect effects on suicidal outcomes via mental health and life events.Limitations
The cross-sectional design and application of measures for different time periods did not allow for causal inferences.Conclusions
Suicidal behaviours were more prevalent than in the general UK population. Interventions targeting low SES individuals may prove effective in preventing suicide attempts. 相似文献11.
Purpose
This study aimed to identify the association of suicidal ideation with job demands and job resources among Japanese workers.Methods
Valid data from questionnaires that were pre-collected from 42,499 workers (34,882 males and 7617 females) were used for multilevel logistic regression analyses. Job demands and job resources were selected as potential predictors of suicidal ideation. Lifestyle variables, support from family and friends, and suffering from depressive or eating disorders were used as covariates.Results
In the employee-level, most job demands and job resources had significant associations with the risk of suicidal ideation in both sexes. High coworker support had a significant negative association with the risk of suicidal ideation in the organization-level, irrespective of their gender. High physical demands and poor physical environment in the organization-level had significant positive associations with increased risk of suicidal ideation only among females.Conclusions
The risk of suicidal ideation among Japanese workers is associated with job demands and job resources in the employee-level, and coworker support in the organization-level may be important as well.12.

Background
The purpose of the study was to examine the association between family history of major depressive disorder (MDD) and mental health service utilization for MDD.Methods
Data come from wave 1 (2001–2002) and wave 2 (2004–2005) of the US National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The AUDADIS was used to determine the presence of lifetime and incident MDD. Participants with a mother, father, grandparent or sibling with MDD were considered to have a positive family history. Mental health service utilization among participants with lifetime MDD was studied. Data were analyzed using logistic regression models adjusted for socio-demographic characteristics (age, sex, education, marital status, family income) and disease severity.Results
Approximately 7940 NESARC participants had lifetime MDD, 54.7% of them had family history of the disorder. Compared to participants with no family history of MDD, those with such family history were two times more likely to access treatment (OR: 2.37, 95% CI: 2.11–2.68). Parental, and particularly maternal history of MDD, was most strongly associated with MDD treatment.Limitations
Data were unavailable on the timing of family history of MDD and its possible under-report, and differences between participants with treated vs untreated relatives. Institutionalized individuals were not included.Conclusions
Individuals with parental and maternal history of major depression were two times more likely to receive treatment for MDD than those with no such history. Efforts to increase access to healthcare for those who do not report family history of MDD could prove effective in addressing existing unmet treatment needs. 相似文献13.
Background
This study involved a multi-level analysis of factors related to self-reported suicidality (both current and life-time) in adolescentsMethods
A sample of 2552 students aged 14–16 years answered questions relating to demographics, social and familial functioning, psychological well-being and suicidality.Results
Suicidality, defined as being at least some element of reported suicide ideation, Behaviourally, suicidality was also more likely if students smoked, drank alcohol without adult supervision or if they took illicit drugs was more likely in girls, and in those with poorer social, family and psychological functioning. Behaviourally, suicidality was also more likely if students smoked, drank alcohol or took illicit drugs. Multi-level modelling showed that negative affect, substance use and the presence of romantic relationships were most strongly associated with suicidality. Both current and life-time measures of suicidality showed similar results. Both models suggested that the presence of substance use in teenagers is a potentially useful indicator of elevated suicide risk and that many of the social problems commonly associated with suicidality are likely to be mediated by negative affective states.Limitations
The study had several limitations. First, it was cross-sectional so it was not possible to examine how variables measured at one time predicted subsequent suicidality. Second, the present analyses were based on a single measure of suicidality that did not differentiate between ideation and attempts. Thus, the analyses did not indicate the severity of the suicidality: whether it involved ideation or actual attempts.Conclusions
Adolescent girls and adolescents with poor social and family functioning and those who engage in substance use are at risk of suicidal ideation (a known precursor of suicide attempts). School counsellors and teachers need to be aware of the risks. 相似文献14.

Background
Child hunger represents an adverse experience that could contribute to mental health problems in later life. The objectives of this study were to: (1) examine the long-term effects of the reported experience of child hunger on late adolescence and young adult mental health outcomes; and (2) model the independent contribution of the child hunger experience to these long-term mental health outcomes in consideration of other experiences of child disadvantage.Methods
Using logistic regression, we analyzed data from the Canadian National Longitudinal Survey of Children and Youth covering 1994 through 2008/2009, with data on hunger and other exposures drawn from NLSCY Cycle 1 (1994) through Cycle 7 (2006/2007) and mental health data drawn from Cycle 8 (2008/2009). Our main mental health outcome was a composite measure of depression and suicidal ideation.Results
The prevalence of child hunger was 5.7% (95% CI 5.0–6.4). Child hunger was a robust predictor of depression and suicidal ideation [crude OR=2.9 (95% CI 1.4–5.8)] even after adjustment for potential confounding variables, OR=2.3 (95% CI 1.2–4.3).Limitations
A single question was used to assess child hunger, which itself is a rare extreme manifestation of food insecurity; thus, the spectrum of child food insecurity was not examined, and the rarity of hunger constrained statistical power.Conclusions
Child hunger appears to be a modifiable risk factor for depression and related suicide ideation in late adolescence and early adulthood, therefore prevention through the detection of such children and remedy of their circumstances may be an avenue to improve adult mental health. 相似文献15.
Background
Patients with Major Depressive Disorder (MDD) often experience unexpected relapses, despite achieving remission. This study examines the utility of a single multidimensional measure that captures variance in patient-reported Depressive Symptom Severity, Functioning, and Quality of Life (QOL), in predicting MDD relapse.Methods
Complete data from remitted patients at the completion of 12 weeks of citalopram in the STAR*D study were used to calculate the Individual Burden of Illness index for Depression (IBI-D), and predict subsequent relapse at six (n=956), nine (n=778), and twelve months (n=479) using generalized linear models.Results
Depressive Symptom Severity, Functioning, and QOL were all predictors of subsequent relapse. Using Akaike information criteria (AIC), the IBI-D provided a good model for relapse even when Depressive Symptom Severity, Functioning, and QOL were combined in a single model. Specifically, an increase of one in the IBI-D increased the odds ratio of relapse by 2.5 at 6 months (β=0.921±0.194, z=4.76, p<2×10−6), by 2.84 at 9 months (β=1.045±0.22, z=4.74, p<2.2×10−6), and by 4.1 at 12 months (β=1.41±0.29, z=4.79, p<1.7×10−6).Limitations
Self-report poses a risk to measurement precision. Using highly valid and reliable measures could mitigate this risk. The IBI-D requires time and effort for filling out the scales and index calculation. Technological solutions could help ease these burdens. The sample suffered from attrition. Separate analysis of dropouts would be helpful.Conclusions
Incorporating patient-reported outcomes of Functioning and QOL in addition to Depressive Symptom Severity in the IBI-D is useful in assessing the full burden of illness and in adequately predicting relapse, in MDD. 相似文献16.
Background
Activation syndrome (AS) is a cluster of symptoms listed by the US Food and Drug Administration as possible suicidality precursors during antidepressant treatment. We aimed to clarify whether AS is associated with bipolar II disorder (BP-II) and its related disorder, i.e., bipolar disorder not otherwise specified (BP-NOS), which are often mistreated as major depressive disorder (MDD), as well as bipolar suggestive features in outpatients with depression.Methods
The frequency of AS, bipolar suggestive features, and background variables in consecutive outpatients with a major depressive episode (MDE) due to BP-II/BP-NOS or MDD, who were naturalistically treated with antidepressants, were investigated and analyzed retrospectively.Results
Of 157 evaluable patients (46 BP-II/BP-NOS, 111 MDD), 39 (24.8%) experienced AS. Patients with BP-II/BP-NOS experienced AS significantly more frequently than patients with MDD (52.2% of BP-II/BP-NOS vs. 13.5% of MDD, p<0.01). Univariate analysis revealed that BP-II/BP-NOS diagnosis, cyclothymic temperament, early age at onset of first MDE, psychiatric comorbidities, and depressive mixed state (DMX) were significantly associated with AS development in the entire sample. Multivariate analysis revealed that BP-II/BP-NOS diagnosis and DMX were independent risk factors for AS.Limitations
This is a retrospective and naturalistic study; therefore, patient selection bias could have occurred.Conclusions
Cautious monitoring of AS is needed during antidepressant trials in patients with BP-II/BP-NOS. Clinicians should re-evaluate underlying bipolarity when they confront AS. Antidepressants should be avoided for treating a current DMX beyond the unipolar–bipolar dichotomy. Prospective studies are needed to confirm these results. 相似文献17.

Background
The corpus callosum and related white matter projections have been implicated in major depressive disorder (MDD). Previously, we found a smaller genu in adolescents with MDD as compared to controls. To date, no study has examined the age of depression onset (adult vs. pediatric) as it relates to genu area in adults with MDD.Methods
The area of the corpus callosum and its sub-regions were measured in 21 MDD subjects with pediatric age of onset (≤18 years) (29.48±7.62 years; 16 female, 5 male) and 31 MDD subjects with adult age of onset (≥19 years) (41.42±8.85; 17 female, 14 male) and 19 healthy controls (32.89±years 9.98; 11 female, 8 male) using magnetic resonance imaging (MRI).Results
A difference in genu area was noted between groups (p=0.03), after co varying for age with post-hoc tests revealing that the difference was driven by the subjects with an MDD onset of pediatric age (p=0.035). No other sub-regions or total corpus callosum area demonstrated a significant difference. Genu area correlated with age in controls (p=0.02) but not in MDD patients (p=0.35). No significant correlation was found between the confound illness duration and genu area in MDD subjects with pediatric age of onset.Limitations
Confirmation and extension of our findings requires a larger sample size and usage of diffusion tensor imaging.Conclusions
Our findings provide additional evidence of abnormalities in the genu of the corpus callosum in early onset depression that persist into adulthood. 相似文献18.

Background
Major Depressive Disorder (MDD) is a leading cause of disability globally. Currently available treatments have limited efficacy and combination strategies are frequently used. Several lines of research have demonstrated that MDD patients experience impairments in various components of affective processing, including regulation of affective states.Aim
To identify baseline and 1-week neuroimaging predictors of response to a 6-week trial of fluoxetine/olanzapine combination treatment during an affective processing task.Methods
Twenty-one MDD patients and 18 healthy controls were enrolled in the study. MDD patients were treated for 6 weeks with fluoxetine (40–60 mg/day) and olanzapine (5–12.5 mg/day). All participants viewed images from the International Affective Picture Rating System during a functional magnetic resonance (fMRI) scan at baseline and 1 week.Results
There was a 57% response rate (defined as a 50% decrease in Hamilton Rating Scale for Depression-17 item) at 6 weeks. At baseline, responders had increased premotor activity while viewing negative images compared to non-responders and healthy controls. Higher baseline premotor activity was also predictive of greater percent change on the HAMD-17 and improvement in negative disposition and behavioral drive. Non-responders exhibited increased insular activity at baseline compared to responders. Higher activity in the posterior cingulate cortex was also predictive of greater percent change on the HAMD-17. Change from baseline to 1 week did not produce any significant predictive findings.Conclusions
Treatment with fluoxetine/olanzapine demonstrated similar biomarkers of response to monotherapeutic strategies. In particular, posterior cingulate cortex, anterior insula, and premotor cortex may show predictive differences in their response to affective images prior to treatment. Further research needs to be conducted to determine the utility of early changes in emotion circuitry in predicting antidepressant response. 相似文献19.

Background
Depression and alcohol misuse are among the most prevalent diagnoses in suicide fatalities. The risk posed by these disorders is exacerbated when they co-occur. Limited research has evaluated the effectiveness of common depression and alcohol treatments for the reduction of suicide vulnerability in individuals experiencing comorbidity.Methods
Participants with depressive symptoms and hazardous alcohol use were selected from two randomised controlled trials. They had received either a brief (1 session) intervention, or depression-focused cognitive behaviour therapy (CBT), alcohol-focused CBT, therapist-delivered integrated CBT, computer-delivered integrated CBT or person-centred therapy (PCT) over a 10-week period. Suicidal ideation, hopelessness, depression severity and alcohol consumption were assessed at baseline and 12-month follow-up.Results
Three hundred three participants were assessed at baseline and 12 months. Both suicidal ideation and hopelessness were associated with higher severity of depressive symptoms, but not with alcohol consumption. Suicidal ideation did not improve significantly at follow-up, with no differences between treatment conditions. Improvements in hopelessness differed between treatment conditions; hopelessness improved more in the CBT conditions compared to PCT and in single-focused CBT compared to integrated CBT.Limitations
Low retention rates may have impacted on the reliability of our findings. Combining data from two studies may have resulted in heterogeneity of samples between conditions.Conclusions
CBT appears to be associated with reductions in hopelessness in people with co-occurring depression and alcohol misuse, even when it is not the focus of treatment. Less consistent results were observed for suicidal ideation. Establishing specific procedures or therapeutic content for clinicians to monitor these outcomes may result in better management of individuals with higher vulnerability for suicide. 相似文献20.
