Presenting problems of parasuicides versus suicide ideators and nonsuicidal psychiatric patients

Early Trauma Is Associated With Suicidal Ideation in Patients With Panic Disorder

ABSTRACT

There are several predictors of suicidality in patients with panic disorder (PD). Being a woman, younger age, low education level, unmarried status, and symptom severity have been suggested. This study aimed to examine whether early trauma is associated with suicidal ideation in patients with PD. Our study included 267 patients with PD and 105 controls. Data on sociodemographic variables and data from the Early Trauma Inventory Self Report-Short Form, Beck Depression Inventory, Panic Disorder Severity Scale, Anxiety Sensitivity Inventory-Revised, Coping Scales, and Scale for Suicide Ideation were collected, and correlation and regression analyses were performed. This study suggests that clinicians should consider early trauma when assessing suicidal ideation in patients with PD. Clinicians could consider alternative treatments, such as trauma-focused cognitive-behavioral therapy, eye movement desensitization, reprocessing approaches, and classical pharmacological and psychological treatments for patients with PD who have a history of early trauma and are expected to be at high risk for suicide.

Central Amygdala Projections to Lateral Hypothalamus Mediate Avoidance Behavior in Rats

Persistent avoidance of stress-related stimuli following acute stress exposure predicts negative outcomes such as substance abuse and traumatic stress disorders. Previous work using a rat model showed that the central amygdala (CeA) plays an important role in avoidance of a predator odor stress-paired context. Here, we show that CeA projections to the lateral hypothalamus (LH) are preferentially activated in male rats that show avoidance of a predator odor-paired context (termed Avoider rats), that chemogenetic inhibition of CeA-LH projections attenuates avoidance in male Avoider rats, that chemogenetic stimulation of the CeA-LH circuit produces conditioned place avoidance (CPA) in otherwise naive male rats, and that avoidance behavior is associated with intrinsic properties of LH-projecting CeA cells. Collectively, these data show that CeA-LH projections are important for persistent avoidance of stress-related stimuli following acute stress exposure.SIGNIFICANCE STATEMENT This study in rats shows that a specific circuit in the brain [i.e., neurons that project from the central amygdala (CeA) to the lateral hypothalamus (LH)] mediates avoidance of stress-associated stimuli. In addition, this study shows that intrinsic physiological properties of cells in this brain circuit are associated with avoidance of stress-associated stimuli. Further characterization of the CeA-LH circuit may improve our understanding of the neural mechanisms underlying specific aspects of stress-related disorders in humans.

Psychosocial Correlates of Suicide Ideation: A Comparison of Chinese and U.S. Rural Women

China is the only country in the world where the suicide rate for women is higher than that for men. In particular there is current concern about a high suicide rate for women living in rural areas. In this study, two samples of young women ages 20 to 35, one from rural China ( n=52) and one from rural United States ( n=52) were interviewed as to suicide ideation and suicide risk, as related to psychosocial variables of self-esteem, coping, social support, and attitudes toward suicide. Significant mean differences were obtained between samples on all eleven variables. The pattern of intercorrelations between variables showed both similarities and differences in the two samples. A stepwise multiple-regression analysis indicated that the same four variables, albeit in different order, were predictive of suicide: these variables were self-esteem, instrumental support, the attitude that suicide is morally bad, and an overall rating of coping.

Suicidal ideations and attempts among adolescents subjected to childhood sexual abuse and family conflict/violence: the mediating role of anger and depressed mood

Based on a sample of 9085 16- to 19-year-old students attending all high schools in Iceland in 2004, the current study examines depressed mood and anger as potential mediators between family conflict/violence and sexual abuse, on the one hand, and suicidal ideations and suicide attempts on the other. Agnew's general strain theory provides the theoretical framework for the study. Structural equation modelling (SEM) was conducted allowing explicit modelling of both direct and mediating effects using observed and latent variables. The findings showed that both depressed mood and anger mediated the relationship between family conflict/violence and sexual abuse and suicidal attempts. However, when testing the mediating pathways between sexual abuse and family conflict/violence and suicidal ideations, only depressed mood but not anger turned out to be a significant mediator. The authors discuss how these finding may inform and facilitate the design and development of interventions to reduce the likelihood of suicide attempts among young people.

Differential profiles of risk of self-harm among clinically referred primary school aged children

Risk of self-harm among clinic referred children aged 6- to 12-years-old was investigated using the recently developed Self-Harm Risk Assessment for Children (SHRAC) instrument which comprises six factors: Affect traits; verbalizing of self-harm; socialization; dissociation; self-directing; and self-appraisal. The SHRAC was completed by the mothers of 125 primary school aged children referred to a University based clinic for psychological assessment. These children were subsequently assigned to one of four groups (non clinical, externalizers, internalizers, and combined internalizers/externalizers). Multivariate analysis of variance with univariate F and Scheffé follow-ups revealed differences in risk of self-harm between the four groups. Overall, individuals with both internalizing (anxiety/withdrawn, anxiety/depressed and somatic complaints) and externalizing (rule-breaking behavior and aggressive behavior) characteristics were more at risk of self-harm. These individuals scored highest across each of the six domains. The findings demonstrate the SHRAC to be a reliable instrument for educational psychologists to use with children they suspect of being at risk of self-harm.

Suicidality as a function of impulsivity, callous-unemotional traits, and depressive symptoms in youth

Suicidality represents one of the most important areas of risk for adolescents, with both internalizing (e.g., depression, anxiety) and externalizing-antisocial (e.g., substance use, conduct) disorders conferring risk for suicidal ideation and attempts (e.g., Bridge, Goldstein, & Brent, 2006). However, no study has attended to gender differences in relationships between suicidality and different facets of psychopathic tendencies in youth. Further, very little research has focused on disentangling the multiple manifestations of suicide risk in the same study, including behaviors (suicide attempts with intent to die, self-injurious behavior) and general suicide risk marked by suicidal ideation and plans. To better understand these relationships, we recruited 184 adolescents from the community and in treatment. As predicted, psychopathic traits and depressive symptoms in youth showed differential associations with components of suicidality. Specifically, impulsive traits uniquely contributed to suicide attempts and self-injurious behaviors, above the influence of depression. Indeed, once psychopathic tendencies were entered in the model, depressive symptoms only explained general suicide risk marked by ideation or plans but not behaviors. Further, callous-unemotional traits conferred protection from suicide attempts selectively in girls. These findings have important implications for developing integrative models that incorporate differential relationships between (a) depressed mood and (b) personality risk factors (i.e., impulsivity and callous-unemotional traits) for suicidality in youth.

Dimensions of adolescent psychopathology and relationships to suicide risk indicators

Youth suicide represents an area of important public and mental health concern. Although diagnostic correlates (e.g., depression) of suicidality have been identified, very few studies of youth have analyzed relationships between empirically-derived dimensions of psychopathology, representing broader dimensions of risk, and different suicidality indicators. We recruited 223 adolescents (57% female; 32% ethnic minority) from mental health agencies and the community to assess psychopathology, substance use, and suicidality relying on multiple measures and reporters (youth, parent, and clinician). Using a 3-factor model of psychopathology, we found that the Internalizing factor (including depression and generalized anxiety) was associated with both suicidal thinking and behaviors (threats/attempts), the Externalizing factor (conduct, oppositional, and attention deficit disorders) was negatively related only to suicidal thinking, and the Substance Use factor (alcohol and cannabis use) related to suicidal behaviors of threats/attempts but not suicidal thinking. The results show the utility of a dimensional conceptualization for clarifying distinct vulnerabilities to suicidal thinking versus overt behaviors and have implications for the construct validity of distinct dimensions of psychopathology.

The role of attachment styles and interpersonal problems in suicide-related behaviors

The relationships among adult attachment styles, interpersonal problems, and categories of suicide-related behaviors (i.e., self-harm, suicide attempts, and their co-occurrence) were examined in a predominantly psychiatric sample (N = 406). Both anxious and avoidant attachment styles were associated with interpersonal problems. In turn, specific interpersonal problems differentially mediated the relations between attachment style and type of suicide-related behaviors. These findings suggest the importance of distinguishing between these groups of behaviors in terms of etiological pathways, maintenance processes, and treatment interventions.

Younger onset of depression is associated with greater suicidal intent

BACKGROUND

Age of onset of major depression seems to be dropping in Western nations. Early onset usually predicts a more serious illness with a relatively poor prognosis. Since depression is associated with suicide, this begs the question of whether early onset of depression is associated with the degree of intent of suicidal behaviour, and whether this relationship differs according to gender.

METHODS

Relevant responses from 9,282 residents of the United States were drawn from a nationally representative community survey conducted in 2001 through 2003 using the W.H.O. version of the Composite International Diagnostic Interview. The primary outcome measure was the retrospectively determined age of first major depressive episode.

RESULTS

Younger age of onset for depression was associated with higher levels of suicidal intent, irrespective of age at the time of interview. A significant interaction between level of intent and age at interview appeared to be accounted for by the later onset among those in the eldest cohort who reported an absence of suicidal behaviour. The influence of suicidal intent on onset of depression was greater for women than for men.

CONCLUSIONS

The earlier the age of first symptoms of major depressive episode, the higher the degree of suicidal intent, irrespective of age at interview and gender, although the more pronounced trend for women suggests a greater sensitivity to underlying factors that may involve depression and lead to suicide risk.

Natural history of suicidal behaviors in a population-based sample of young adults

BACKGROUND

Suicidal behaviors in young individuals represent an important public health problem. Understanding their natural history and relationships would therefore be of clinical and research value. In this study, we examined the natural histories of several suicidal behaviors and investigated two conceptual models of suicidality (dimensional and categorical) in the context of adolescent and adult-onset suicide attempts.

METHOD

Participants were members of a prospectively studied, representative, population-based school cohort followed since age 6 (n = 3017) through mid-adolescence (n = 1715) to their early twenties (n = 1684). Outcome measures included suicidal ideation, attempts and completions.

RESULTS

Approximately one in 500 individuals died by suicide. About 33% had suicidal ideas and 9.3% made at least one suicide attempt. Over half (4.9%) of the self-reported attempters made their first attempt before age 18. With the exception of current suicidal ideas, non-fatal suicidal behaviors were more prevalent in females. In general, parental and cross-sectional self-reports underestimated suicidality rates. Aikaike (AIC) and Bayesian (BIC) information criteria suggested the ordinal model, and dimensional conceptualization of suicide attempts of different onset age, to be more optimal than its multinomial/categorical counterpart (ordinal: AIC 567.55, BIC 635.67; multinomial: AIC 616.59, BIC 723.83). Both models, nevertheless, identified five common factors of relevance to suicidal diathesis: gender, disruptive disorders, childhood anxiousness and abuse, and suicidal thoughts.

CONCLUSIONS

Non-fatal suicidal behaviors in adolescents and young adults are more common than suggested by cross-sectional studies and parental reports. The dimensional model may be more useful in explaining the relationship of suicide attempts of different age of onset.

Coping, symptoms, and functioning outcomes of patients with posttraumatic stress disorder

This study examines the association between approach coping and better functioning outcomes and the reciprocal relationships between coping and posttraumatic stress disorder (PTSD) symptoms in patients diagnosed with PTSD. Posttraumatic stress disorder patients receiving services in five VA health care systems were randomly selected and surveyed at baseline and followed 10 months later. Analyses of longitudinal data using structural equation modeling techniques showed that more approach coping predicted better family and social functioning. Cognitive avoidance coping predicted more PTSD symptoms, and more PTSD symptoms predicted more approach coping and more behavioral avoidance coping. Approach coping may enable patients with chronic PTSD to establish and maintain better relationships with family and friends, despite continuing PTSD.

The relationship between suicide attempts and low-lethal self-harm behavior among psychiatric inpatients

In this study, we examined the relationship between suicide attempts and low-lethal self-harm behavior in a sample of psychiatric inpatients. Using a cross-sectional approach, we surveyed 107 participants about their histories of suicide attempts, including overdoses, as well as various low-lethal self-harm behaviors. Compared with those without such histories, individuals with histories of suicide attempts, including overdoses, were significantly more likely to report a greater number of: 1) low-lethal self-harm behaviors; 2) specific symptom clusters of self-harm behavior (i.e., self-mutilation, substance abuse, medically self-defeating behaviors); and 3) specific individual self-harm behaviors (e.g., torturing oneself with self-defeating thoughts, abusing prescription medications). These data suggest that suicide attempts and low-lethal self-harm behavior are likely to co-exist in many psychiatric inpatients.

Psychological predictors of weight regain in obesity

It is a consistent finding that, among obese patients, the weight lost as a result of the most widely available treatments for obesity is almost always regained. This relapse appears to be attributable to the individual's inability to persist with the behavioural strategies needed to maintain the new lower weight. Little research has investigated the psychological mechanisms that might account for this phenomenon. This study aimed to identify psychological factors that predict weight regain. Fifty-four women with obesity who had lost weight by attending community slimming clubs were interviewed immediately after losing 10% of their initial body weight, and then followed-up every 2 months for a period of 1 year by means of telephone interviews. The results identified two prospective predictors of weight regain: one cognitive factor (dichotomous thinking) and one historical variable (maximum lifetime weight). The finding that a specific cognitive style is a significant predictor of relapse has implications for the treatment of obesity.

High-risk situations associated with parasuicide and drug use in borderline personality disorder

Both parasuicide and drug use continue to be difficult problems to treat in borderline personality disorder (BPD). One useful approach that has not yet been applied to BPD is to develop a taxonomy of triggering situations for these problems. Once these high-risk precipitants are identified, then the behaviors can be targeted with skills training. This model has been applied by Marlatt (1996) with very influential results. To examine high-risk situations for parasuicide and drug use in BPD, the current study examined women with BPD who came to treatment for two different primary problems: parasuicide (N = 75) and drug dependence (N = 47). Participants identified the situation associated with highest risk for relapse in either the parasuicide or drug category. A taxonomy is presented, which divides results into six main categories. Differences between high-risk situations for drugs and parasuicide were also explored. Parasuicide was significantly more likely to be linked to interpersonal problems, whereas drug use was more likely to be preceded by addiction cues (i.e., being near drugs or people who use drugs).

Personality correlates of hopelessness in depressed inpatients 50 years of age and older

In this study we examined the relationship between scores on the Beck Hopelessness Scale and the personality traits that constitute the Five-Factor Model in a sample of 77 depressed inpatients, 50 years of age and older. Multiple regression analyses showed that Hopelessness is related to low Extraversion domain scores, and to specific facets of both Extraversion (low positive emotions) and Neuroticism (low self-consciousness, high impulsiveness). Efforts to tie Hopelessness with the motivational, affective, and interpersonal constructs subsumed under Extraversion are warranted.

Coping style of substance-abuse patients: effects of anxiety and mood disorders on coping change

The authors studied the coping style of substance-abuse patients during clinical cognitive-behavioral group therapy, and the effects of mood and anxiety disorders on changes in coping style. Change in coping style was studied prospectively in a cohort of 132 residential-drug-abuse patients. In addition to pretreatment assessments, which included diagnosis of mood and anxiety disorders and addiction severity, repeated measurements of coping style were performed at predetoxification, pretreatment, and after three and six months of treatment. Considerable change in coping style between predetoxification and pretreatment was found, suggesting that coping assessment in a predetoxification phase is confounded by state factors surrounding treatment entry. Coping style of detoxified substance abusers is related to the presence of mood and anxiety disorders. Coping style was not found to be related to the severity of drug abuse. Furthermore, maladaptive coping styles decreased after three months of inpatient-substance-abuse treatment, and more-adaptive coping styles remained stable for another three months of inpatient treatment. Patients with an anxiety disorder improved less on coping style when compared to non-anxiety patients. Presence of a mood disorder had no impact on coping-style improvement. The results indicate that more attention should be focused on anxiety disorders during substance-abuse treatment in order to improve coping style. Furthermore, more studies are needed on the relation between substance abuse, coping style, and psychopathology.

Do adolescents who take overdoses have specific psychological characteristics? A comparative study with psychiatric and community controls

OBJECTIVE

To determine whether specific psychological factors characterize adolescents who take overdoses.

METHOD

Measures of problem-solving, depression, anger, impulsivity, and self-esteem were investigated in 33 adolescents after an overdose, 30 psychiatric controls, and 30 community controls, the groups being matched for age and sex. All subjects were interviewed twice, 6 weeks apart. The first interview in the overdose group followed an overdose.

RESULTS

Significant differences were found between the 3 groups on all of the variables at both interviews. However, when depressive affect (Beck Depression Inventory) was controlled for, all of these differences disappeared, except for impulsivity at the second interview. Here the overdose group remained more impulsive than the other groups even when depression was considered.

CONCLUSIONS

Depression is the most important factor in the presentation of a range of psychological characteristics of adolescents who take overdoses, and this remains true at 6-week follow-up. Impulsivity is apparently an important factor, independent of depression, in adolescent self-poisoning. Further research is required to determine the mediating role of impulsivity in this behavior and to identify treatment strategies for it.

Characteristics and psychosocial problems of patients with bipolar disorder at high risk for suicide attempt

BACKGROUND

Bipolar disorder with a history of substance abuse or suicide attempt is a strong predictor of suicide. A high comorbidity of substance use disorders may obscure the specificity of findings about suicide behaviors in Western patients with bipolar disorder.

METHODS

The clinical data of Chinese bipolar patients (DSM-III-R) in Taiwan who had been naturalistically followed up for at least 15 years were obtained by a combination of chart reviews and interviews with patients and family members. The national identity numbers were used to search for deceased subjects.

RESULTS

There were 158 patients originally included for chart review; 4 of them died from suicide. A 9.9% lifetime prevalence of alcohol use disorders was found in 101 final subjects who accepting interview. Multiple logistic regression showed that subjects with a history of suicide attempt (n = 53, 52.5%) were more likely to have interpersonal problems with spouse or romantic partner (adjusted odds ratio = 2.85, 95% C.I. = 0.69-11.51), occupational problems mainly maladjustment and frequently changing job (adjusted odds ratio = 3.08, 95% C.I. = 1.12-10.49), and an earlier age (< or = 22 years) of onset (adjusted odds ratio = 0.96, 95% C.I. = 0.90-1.02).

LIMITATION

To use an interview schedule for assessing the psychosocial problems of clinical population limits the interpretation and generalisability of the data.

CONCLUSION

Despite low comorbidity of alcohol/drug use disorders in Chinese bipolar patients, a consistently high rate of suicide attempts reinforces that bipolar disorder is a high-risk group of suicide. An earlier age of onset, interpersonal problems with spouse or romantic partner, and occupational maladjustment rather than demographic characteristics may collectively identify those at high risk of suicide attempt in bipolar disorder.

Coping styles and suicide risk

A total of 30 psychiatric in-patients admitted because of suicidal behaviour were compared with 30 non-suicidal psychiatric in-patients and 32 healthy controls on measures of suicide risk and coping styles. The three groups were similar with regard to demographic variables, but the suicidal group scored higher on the suicide risk scale. Suicidal patients were significantly less likely to use the coping styles of minimization and mapping. They were unable to de-emphasize the importance of a perceived problem or source of stress. They also lacked the ability to obtain new information required to resolve stressful life events. Four coping styles correlated negatively with the suicide risk (minimization, replacement, mapping and reversal), while another three (suppression, blame and substitution) correlated positively. These findings may have important implications for therapists and primary prevention workers, and might pave the way towards recognition of the role played by coping styles in predicting suicide and its use for cognitive intervention in these high-risk patients.

Suicidal behavior as related to social support and assertiveness among Swedish and Turkish high school students: a cross-cultural investigation

Among 652 Swedish and 654 Turkish adolescents, the study found that 61 Swedish (9.4%) and 71 Turkish (10.9%) adolescents reported that they had made previous suicide attempts. Previous psychiatric contact, female gender, low perceived family support, and suicide attempts in the family for the Swedish group and suicide attempts in the family, low perceived family support, psychiatric disorder in the family, and previous psychiatric contact variables in the Turkish sample were found to be associated with previous attempts. Low perceived family support, previous suicide attempts, low perceived peer support, female gender, previous psychiatric contact, low positive assertion skills, and a small number of friends for the Swedish; and low perceived family support, previous suicide attempts, low perceived peer support, suicide attempts in the family, and previous psychiatric contact variables for the Turkish group were found to be significant predictors of current suicidal risk.

Suicide and violence risk. I. Relationship to coping styles

Thirty suicidal psychiatric inpatients were compared with 30 nonsuicidal psychiatric inpatients. A battery of self-report tests was administered measuring suicide risk, violence risk and coping styles. The suicidal patients scored higher on both the suicide risk and violence risk. They also used almost all coping styles less frequently than the nonsuicidal patients. Among suicidal patients, suicide risk was negatively correlated with the coping styles of minimization, replacement and blame. Further, suicide risk and violence risk in suicidal patients were shown to be predicted by coping styles. These data indicate that suicidal patients have inadequate mental resources to deal with life problems. Besides their significance for assessing suicide risk, the findings may have possible clinical implications for case detection and early intervention with potential preventive value.

Correlates of suicide and violence risk in an inpatient population: coping styles and social support

Forty-six suicidal psychiatric inpatients were compared with 44 nonsuicidal psychiatric inpatients on measures of suicide risk, violence risk, impulsivity, feelings of anger, social support, and eight coping styles. The two groups were similar on demographic variables, but the suicidal patients were higher on the suicide risk scale, the violence risk scale, the impulsivity scale, and feelings of anger. Suicidal patients were significantly less likely to use the coping style of minimization to deal with life problems. A negative correlation was found between the social support measure and both suicide risk and violence risk. Three coping styles were found to correlate negatively with violence risk, but none with suicide risk. Coping styles were found to be a better predictor of violence risk than of suicide risk. It was also found that the more variables included in the predictor equation, the higher the correlation with the risk measures.

Cognitive predictors of suicide risk among hospitalized psychiatric patients: a prospective study

This prospective study examined the utility of several cognitive variables as predictors of suicide risk among 79 hospitalized psychiatric patients. These variables included pessimism (measured by the Hopelessness Scale), perceived and actual problem-solving ability (indexed by the Problem-Solving Inventory and Means-End Problem-Solving test, respectively), and polarized thinking, self-negativity, and construct system constriction and differentiation (derived from a repertory grid). Suicide risk was operationalized in terms of subsequent self-report of suicide ideation and staff records of time spent on suicide precautions. Results indicated that hopelessness, self-negativity, and poor problem-solving performance functioned as reliable predictors of suicide risk, whereas self-evaluated problem-solving ability did not. Interestingly, constriction emerged as a significant inverse predictor across.

Why parasuicides repeat despite problem resolution

To discover why parasuicides who resolved their difficulties repeated self-harm within three-month follow-up at the same rate as those who had not resolved problems, a group of 30 repeaters was compared with 156 non-repeaters. The repeaters had a history of more frequent episodes, beginning younger. Their problems were more severe, the acts of self-harm potentially less lethal. They experienced greater feelings of externally directed hostility, powerlessness, and 'normlessness'. A constellation of nine variables correctly predicted 81.5% of the repeaters and 77.5% of the non-repeaters. At follow-up the non-repeaters had improved on several parameters but the repeaters were essentially unchanged. The resolvers among the subgroup of repeaters were more like repeaters in the overall sample than the resolvers, which may explain why some parasuicides repeat in spite of resolving their problems.

Features associated with suicide attempts in recurrent major depression

Sixty-seven individuals with recurrent major depression and a history of suicide attempts are compared with 163 individuals with recurrent major depression and no history of suicide attempts. The groups are contrasted on demographic features, clinical course, severity of depression, co-morbidity, and acute symptom profiles. Patients with a history of attempts are distinguished from non-attempters by suicidal ideation, marital isolation, neurovegetative signs, feelings of failure, and co-morbid alcoholism or bipolar II disorder. Logistic regression analysis using a model which included a portion of the significant variables correctly classified 77% of the cases. These findings are discussed with reference to prediction of suicide attempts in individuals with major affective disorder.
