Emotional reactivity and cognitive regulation in anxious children

Recent models of anxiety disorders emphasize abnormalities in emotional reactivity and regulation. However, the empirical basis for this view is limited, particularly in children and adolescents. The present study examined whether anxious children suffer both negative emotional hyper-reactivity and deficits in cognitive emotion regulation. Participants were 49 children aged 10-17 with generalized anxiety disorder, social anxiety, or separation anxiety disorder as their primary diagnosis, as well as 42 age- and gender-matched non-anxious controls. After completing a diagnostic interview and self-report questionnaires, participants were presented with pictures of threatening scenes with the instructions either to simply view them or to use reappraisal, a cognitive emotion regulation strategy, to decrease their negative emotional response. Emotion ratings, content analysis of reappraisal responses, and reports of everyday use of reappraisal were used to assess negative emotional reactivity, reappraisal ability, efficacy and frequency. Relative to controls, children with anxiety disorders (1) experienced greater negative emotional responses to the images, (2) were less successful at applying reappraisals, but (3) showed intact ability to reduce their negative emotions following reappraisal. They also (4) reported less frequent use of reappraisal in everyday life. Implications for the assessment and treatment of childhood anxiety disorders are discussed.

Impulsivity as a correlate of suicidal behavior in adolescent psychiatric inpatients

One hundred and eighteen inpatient adolescents in a psychiatric hospital were evaluated to determine the relationship of aggression, self injury, and suicidal behavior to impulsivity. It was hypothesized that all these variables would be significantly and positively correlated with one another. This hypothesis was in part based on the results of psychobiological research that found serotonin dysfunction to be the common denominator of these psychopathological dimensions. As predicted, a significant correlation was found between the measures of suicidal behavior, aggressive behavior, and impulsivity. This correlation between suicidal behavior and impulsivity remained after partialing out the factor of aggression. Furthermore, the correlations between impulsivity and suicidality appeared greater in males than in females. Since male suicide attempters are more likely to eventually commit suicide than female suicide attempters, these findings may have a bearing on suicide prediction.

The association between adult attachment style and mental health in extreme life-endangering conditions

Abstract This study examines the association between adult attachment style and psychopathology in extreme life-endangering conditions. A group of 40 Israeli Jewish settlers who lived within the Palestinian Authority territory (high-threat group) were asked to fill out an attachment style scale and psychiatric symptomatology measures. They were compared to a control group of Israeli Jewish persons who lived within the State of Israel. Findings showed higher symptomatology in the high-threat than control group. Secure attachment style was inversely related to symptomatology measures. In contrast, anxious–ambivalent and avoidant attachment styles were positively related to symptomatology measures. However, whereas the anxious–ambivalent attachment style was related to psychopathology in the two threat conditions, the avoidant style was related to psychopathology only in the high-threat group. Results were discussed in terms of attachment theory.

Mental pain and its communication in medically serious suicide attempts : An impossible situation

BACKGROUND The study of near-fatal suicide attempters may provide insight into the minds of suicidal subjects. Our aim is to test the hypothesis that mental pain is a general risk factor for suicidal behavior and communication difficulties are a particular risk factor for medically serious suicidal behavior. METHODS Thirty five subjects who made medically serious suicide attempts were compared with 67 medically not serious suicide attempters and 71 healthy controls. All were interviewed with the SCID-I and completed questionnaires covering mental pain, communication difficulties and seriousness of suicide attempt. RESULT Variables from the mental pain domain (e.g. depression) predicted the presence of suicidal behavior, and variables from the communication difficulties domain (e.g., self-disclosure) predicted the lethality and seriousness of the suicide attempts. LIMITATIONS Relatively small number of patients with medically serious suicide attempt and the relatively large number of questionnaires which may to some extent have diminished informant reliability. CONCLUSIONS Problems with sharing of feelings with others are an important risk factor for near-lethal suicide, over and above the contribution of psychiatric illness and mental pain, including depression and hopelessness.

Comparison of the suicidal behavior of adolescent inpatients with borderline personality disorder and major depression

The objective of the study was to examine the hypothesis that some forms of suicidal behavior among adolescents are related to helplessness and depression, whereas others are related to anger and impulsivity. Sixty-five adolescents were studied. Thirty-three had borderline personality disorder (BPD), of whom 17 had made a recent suicide attempt. Thirty-two had major depressive disorder (MDD), of whom 16 had made a recent suicide attempt. Assessments were made with the Child Suicide Potential Scale, the Beck Depression Inventory, the Beck Hopelessness Scale, the Multidimensional Anger Inventory, the Overt Aggression Scale, the Impulsiveness-Control Scale, and the Suicide Intent Scale. Adolescents with BPD had more anger, aggression, and impulsiveness than those with MDD, but similar levels of depression and hopelessness. Suicidal versus nonsuicidal adolescents were more depressed, hopeless, and aggressive, but not more angry or impulsive. There were no significant differences in impulsiveness for the MDD suicidal group versus the MDD nonsuicidal group, but the suicidal BPD adolescents were significantly more impulsive than the nonsuicidal BPD adolescents. In the subjects with BPD, impulsiveness and aggression correlated significantly and positively with suicidal behavior. In the subjects with MDD, no such correlations were seen. In both diagnostic groups, depression and hopelessness correlated positively and significantly with suicidal behavior. Anger did not correlate with suicidal behavior in either of the groups. The suicidal subjects with MDD had significantly higher suicidal intent scores than the suicidal adolescents with BPD. We conclude that the nature of suicidal behavior in adolescents with BPD differs from that seen in MDD with respect to the role of anger and aggression.

Self-Report vs. Computerized Measures of Impulsivity as a Correlate of Suicidal Behavior

OBJECTIVES To compare the use of a self-report form of impulsivity versus a computerized test of impulsivity in the assessment of suicidal adolescent psychiatric inpatients. METHODS Sixty consecutive admissions to an adolescent in patient unit were examined. The severity of suicidal behavior was measured with the Childhood Suicide Potential Scale (CSPS), and impulse control was measured with the self report Plutchik Impulse Control Scale (ICS) and with the Test of Variables of Attention (TOVA), a continuous performance test (CPT). The TOVA is used to diagnose adolescents with attention deficit disorder. RESULTS There was a significant but low correlation between the two measures of impulsivity. Only the TOVA commission and omission errors differentiated between adolescent suicide attempters and nonattempters. CONCLUSIONS Computerized measures of impulsivity may be a useful way to measure impulsivity in adolescent suicide attempters. Impulsivity appears to play a small role only in nondepressed suicidal adolescents, especially boys.

A Comparison of Life Events Between Suicidal Adolescents With Major Depression and Borderline Personality Disorder

The current study compared the correlations of different types of stressful life events (SLE) between suicidal adolescents with major depressive disorder (MDD) and suicidal adolescents with borderline personality disorder (BPD). Both groups were referred following an attempted suicide. Twenty adolescents with MDD and 20 adolescents with BPD who were consecutively referred to an outpatient clinic following a suicide attempt were evaluated. A community control group of adolescents with no lifetime history of suicidal behavior was also assessed. The following measurements were employed: the Suicide Risk Scale (SRS) Beck Depression Inventory (BDI), the Life Events Checklist (LEC), and the Childhood Sexual Abuse Questionnaire (CSEQ). Both groups of suicidal subjects reported more SLE in general and more physical abuse than community controls in the 12 months before the suicide attempt. The MDD adolescents had more lifetime death-related SLE than the BPD and control groups, while the BPD adolescents reported more lifetime sex abuse-related SLE than the other two groups. Thus, suicidal behavior in general may be related to the amount of SLE. However, different disease-specific life events may precipitate suicide attempts in adolescents with MDD and BPD.

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.

A comparison of life events in patients with unipolar disorder or bipolar disorder and controls.

OBJECTIVE The present study aimed to explore the association between stressful life events (LEs) and the development of affective psychopathology. METHOD Thirty patients with unipolar disorder and 30 patients with bipolar disorder were compared to 60 matched healthy controls in regard to the rate of stressful LEs. Assessment measures included the Beck Depression Inventory, the Adult Life Events Questionnaire, and the Childhood Life Events List. RESULTS The entire sample of affective patients had more LEs in general, more negative LEs, and more loss-related LEs in the year preceding their first depressive episode as compared with normal controls. Subjects with unipolar disorder had more positive LEs and more achievement LEs, whereas subjects with bipolar disorder had more uncontrollable LEs in the year preceding the first depressive episode. The relationship between LEs and manic episodes was prominent in the year preceding the first manic episode, with subjects with bipolar disorder reporting more LEs in general and more ambiguous events in that year. Almost no significant differences on LE frequency were observed in the year before the last depressive and manic episodes in the patient groups with unipolar and bipolar disorder. A significant relationship was found between childhood LEs and the development of affective disorders in adulthood, with patients with unipolar disorder exhibiting less positive and achievement LEs. CONCLUSIONS In both the unipolar and the bipolar groups, the major impact of LEs on the onset of affective disorders was found in the year before the first depressive or manic episodes. This suggests that the accumulation of stressful LEs at this crucial period contributes to the precipitation of a pathological response mechanism. Once established, this mechanism would be reactivated in the future by even less numerous and less severe stressors, compatible with the kindling hypothesis.

Post-adoption depression among adoptive mothers

OBJECTIVE To evaluate the rate of depressive symptomatology and possible underlying factors in adoptive mothers during the transition to motherhood. DESIGN Cohort survey. SETTING General Community. PARTICIPANTS Thirty-nine adoptive mothers of reproductive age registered with international adoption agencies. INTERVENTIONS All women completed the Edinburgh Postnatal Depression Scale (EPDS), the Beck Depression Inventory (BDI), and the Brief Symptom Inventory (BSI) before and 6 weeks after the adoption. MAIN OUTCOME MEASURES Responses were compared between the study group and published findings for biological mothers in the general population, and within the study group, before and after adoption. RESULTS Symptoms of depression were found in 15.4% of the study group. This rate was similar to that for postpartum depression in the general population, and lower than the rate recorded in the study group before adoption (25.6%). All women with symptoms of depression after the adoption had also shown evidence of depressive features before the adoption. Similar findings were noted for other psychopathologies as well. CONCLUSION Adopting a child does not cause new-onset, reactive depression among adoptive mothers. It may even lead to a decrease in depressive features, perhaps in response to relief from other adjustment difficulties.
