Intergenerational transmission and continuity of stress and depression: depressed women and their offspring in 20 years of follow-up

BACKGROUND

Children of depressed mothers not only have higher risk of depression, but also may experience both elevated and continuing exposure to stressful experiences. The study tested hypotheses of the intergenerational transmission of stress and depression and examined the role of early childhood adversity and maternal depression in the interplay between youth depression and stress over 20 years.

METHOD

In a longitudinal community study of 705 families selected for history or absence of maternal depression, mothers and youth were studied from pregnancy to age 5 years and at youth ages 15 and 20 years. Youth and maternal depression were assessed with diagnostic interviews, acute and chronic interview-based stress assessment in the youth and contemporaneous measures of childhood adversity obtained between pregnancy and youth age 5 years.

RESULTS

Regression analyses indicated evidence of intergenerational transmission and continuity of depression over time, continuity of acute and chronic stress and reciprocal predictive associations between depression and stress. Maternal depression and exposure to adversities by child's age 5 years contributed to the youth's continuing experiences of depression and stress. An overall path model was consistent with stress continuity and intergenerational transmission and highlighted the mediating role of age 15 youth chronic interpersonal stress.

CONCLUSIONS

Youth of depressed mothers are at risk not only for depression but also for continuing experiences of acute and chronic stress from childhood to age 20. The associations among depression and stress are bidirectional and portend continuing experiences of depression and further stress.

Early childhood adversity and adolescent depression: the mediating role of continued stress

BACKGROUND

While various conceptualizations of the link between childhood adversity and later depression have been offered, most have not accounted for the possibility that early adversity predicts continuing stress proximal to depression onset. Thus, the present study tested the possible mediating role of recent stress in the association between early adversity and depression in late adolescence.

METHOD

Study questions were examined in a longitudinal community sample of 705 youth who were contemporaneously assessed for early adversity exposure prior to age 5 years, chronic and episodic stress at age 15 years, and major depression prior to age 15 years and between 15 and 20 years.

RESULTS

Total youth stress burden at age 15 years mediated the effect of early adversity on depression between ages 15 and 20 years, and none of the observed relationships were moderated by onset of depression prior to age 15 years.

CONCLUSIONS

These findings suggest that continued stress exposure proximal to depression onset largely accounts for the association between early adversity and depression in late adolescence. Intervention should thus focus on disrupting the continuity of stressful conditions across childhood and adolescence. Future studies of the neurobiological and psychosocial mechanisms of the link between early experiences and depression should explore whether the effects of early experiences are independent of continuing adversity proximal to depressive onset.

Social stress and women's risk for recurrent depression

The lives of depressed women appear to be stressful. Based on data from a community sample of women with histories of depression, support for an interpersonal stress perspective on women's depression is presented. Women often find themselves embedded in environments with high levels of chronic stress and negative life events. Compared to never-depressed women, those who are currently depressed, and even those with prior but not current depression, are relatively more likely to experience divorce and marital difficulties, spouses with psychiatric disorders, problematic relationships with their children, children with high rates of disorder, and recent elevated rates of personal stressful life events. Such life challenges may increase the likelihood of further depressive experiences. While both psychosocial and genetic factors may contribute to the interpersonal vulnerabilities, once caught up in depression-maintaining environments, treatments for women may require intervention in the family and interpersonal domains.

Depressed adolescents of depressed and nondepressed mothers: tests of an interpersonal impairment hypothesis

Two groups of depressed youngsters were compared. From an interpersonal perspective, it was hypothesized that depressed adolescents of depressed mothers would have significantly more interpersonal dysfunction than depressed youngsters of nondepressed mothers. In a large community sample of youth and their families, 65 depressed offspring of women with histories of a major depressive episode or dysthymia were compared with 45 depressed offspring of never-depressed women. As predicted, after controlling for current symptoms and family social status variables, depressed offspring of depressed mothers displayed significantly more negative interpersonal behaviors and cognitions compared with depressed offspring of nondepressed mothers, but they did not differ on academic performance. Implications concerning mechanisms, course, and consequences of different forms of adolescent depression are presented.

Chronicity, severity, and timing of maternal depressive symptoms: relationships with child outcomes at age 5

The relationships between severity, chronicity, and timing of maternal depressive symptoms and child outcomes were examined in a cohort of 4,953 children. Mothers provided self-reports of depressive symptoms during pregnancy, immediately postpartum, and when the child was 6 months old and 5 years old. At the age 5 follow-up, mothers reported on children's behavior and children completed a receptive vocabulary test. Results suggest that both the severity and the chronicity of maternal depressive symptoms are related to more behavior problems and lower vocabulary scores in children. The interaction of severity and chronicity of maternal depressive symptoms was significantly related to higher levels of child behavior problems. Timing of maternal symptoms was not significantly related to child vocabulary scores, but more recent reports of maternal depressive symptoms were associated with higher rates of child behavior problems.

Parental anxiety disorders, child anxiety disorders, and the perceived parent-child relationship in an Australian high-risk sample

This study was designed to explore the role of perceived parenting behavior in the relationship between parent and offspring anxiety disorders in a high-risk sample of adolescents. We examined the relationship between parental and child anxiety disorders and tested whether perceived parenting behavior acted as a mediator between these variables. Analyses were performed on a high-risk sample of 816 fifteen-year-olds drawn from a birth cohort in Queensland, Australia. Parental depression and income were covaried. Maternal anxiety disorder significantly predicted the presence of anxiety disorders in children; the association between paternal anxiety disorder and child anxiety disorder was not significant. There was no evidence that perceived parenting played a mediating role in the association between mother and child anxiety disorders. These results replicate earlier studies' findings of elevated rates of anxiety disorders among the offspring of anxious parents, but only when the child's mother is the anxious parent.

Chronicity, severity, and timing of maternal depressive symptoms: relationships with child outcomes at age 5

The relationships between severity, chronicity, and timing of maternal depressive symptoms and child outcomes were examined in a cohort of 4,953 children. Mothers provided self-reports of depressive symptoms during pregnancy, immediately postpartum, and when the child was 6 months old and 5 years old. At the age 5 follow-up, mothers reported on children's behavior and children completed a receptive vocabulary test. Results suggest that both the severity and the chronicity of maternal depressive symptoms are related to more behavior problems and lower vocabulary scores in children. The interaction of severity and chronicity of maternal depressive symptoms was significantly related to higher levels of child behavior problems. Timing of maternal symptoms was not significantly related to child vocabulary scores, but more recent reports of maternal depressive symptoms were associated with higher rates of child behavior problems.

Toward an interpersonal life-stress model of depression: the developmental context of stress generation

The validity of a developmentally based life-stress model of depression was evaluated in 88 clinic-referred youngsters. The model focused on (a) the role of child-environment transactions, (b) the specificity of stress-psychopathology relations, and (c) the consideration of both episodic and chronic stress. Semistructured diagnostic and life-stress interviews were administered to youngsters and their parents. As predicted, in the total sample child depression was associated with interpersonal episodic and chronic stress, whereas externalizing disorder was associated with noninterpersonal episodic and chronic stress. However, the pattern of results differed somewhat in boys and girls. Youngsters with comorbid depression and externalizing disorder tended to experience the highest stress levels. Support was obtained for a stress-generation model of depression, wherein children precipitate stressful events and circumstances. In fact, stress that was in part dependent on children's contribution distinguished best among diagnostic groups, whereas independent stress had little discriminative power. Results suggest that life-stress research may benefit from the application of transactional models of developmental psychopathology, which consider how children participate in the construction of stressful environments.

Depression and sensitization to stressors among young women as a function of childhood adversity

The authors tested a stress-sensitization version of a diathesis-stress approach to depression. In a 2-year longitudinal follow-up design, exposure to stressful life events was examined in young women in the transition to adulthood. The authors hypothesized that those who had experienced one or more significant childhood adversities would have a lower threshold for developing a depressive reaction to stressors. Results indicated that women with exposure to one or more childhood adversities--such as family violence, parent psychopathology or alcoholism, and others--were more likely to become depressed following less total stress than women without such adversity. The results could not be accounted for by chronic stress or prior depression. Both biological and psychological sensitization mechanisms may be speculated to play a role, but the actual mechanisms of stress sensitization remain to be explored.

Predictors of first onset and recurrence of major depression in young women during the 5 years following high school graduation

Although most depressive episodes in adulthood are recurrences of the disorder, lifetime history of major depression (MD) is often neglected in predictive models. On the basis of research and theory suggesting differential prediction of MD across the course of the disorder, the authors explored whether factors that predict a first MD onset would not predict MD recurrence. Predictors of MD were examined longitudinally in a sample of 128 young women followed for 5 years. Controlling for lifetime MD history, 5-year MD was predicted by the presence before study entry of 3 variables: having witnessed family violence before age 16, having a parent with a psychiatric disorder, and having a nonmood Axis I disorder. During the follow-up period, chronic and episodic stress predicted MD. Prior lifetime MD interacted with both chronic stress and parental psychopathology to predict MD, such that first onsets, but not recurrences, were predicted by these risk variables.

Predictors of work adjustment in bipolar I patients: a naturalistic longitudinal follow-up

This study explored the clinical and psychosocial predictors of work adjustment in 52 Bipolar I patients over a 2-year longitudinal period and examined associations between work functioning and social relationships, personality features, stressful life events, and clinical variables. Analyses indicated that psychosocial variables (personality disorder symptoms and social functioning) added significantly to prediction of work functioning after clinical variables were entered. Stressful life events were not associated with work adjustment. Overall, presence of a good quality supportive relationship was the strongest unique predictor of work. The results highlight the need to study functional outcomes in patients, especially because they appear only modestly associated with clinical status.

Gender and bipolar illness

BACKGROUND

For major depression and schizophrenia, gender differences have been reported in symptom expression and course of illness. Gender differences in bipolar disorder are becoming increasingly apparent, but have been less studied. Research data on these differences will help determine whether gender is important in influencing illness variables such as course, symptom expression, and likelihood of comorbidity.

METHOD

Charts of 131 patients (63 women and 68 men) with a DSM-IV diagnosis of bipolar disorder admitted to the University of California Los Angeles Mood Disorders Program over a 3-year period were reviewed to gather data on demographic variables and course of illness and to assess differences in the illness across genders.

RESULTS

No significant gender differences were found in the rate of bipolar I or bipolar II diagnoses, although women were overrepresented in the latter category. Also, no significant gender differences emerged in age at onset, number of depressive or manic episodes, and number of hospitalizations for depression. Women, however, had been hospitalized significantly more often than men for mania. Further, whereas bipolar men were significantly more likely than bipolar women to have a comorbid substance use disorder, women with bipolar disorder had 4 times the rate of alcohol use disorders and 7 times the rate of other substance use disorders than reported in women from community-derived samples.

CONCLUSION

For bipolar disorder, course of illness variables such as age at onset and number of affective episodes of each polarity do not seem to differ across genders. Women, however, may be more likely than men to be hospitalized for manic episodes. While both men and women with the illness have high rates of comorbidity with alcohol and other substance use disorders, women with bipolar disorder are at a particularly high risk for comorbidity with these conditions.

Predictors of work adjustment in bipolar I patients: a naturalistic longitudinal follow-up

This study explored the clinical and psychosocial predictors of work adjustment in 52 Bipolar I patients over a 2-year longitudinal period and examined associations between work functioning and social relationships, personality features, stressful life events, and clinical variables. Analyses indicated that psychosocial variables (personality disorder symptoms and social functioning) added significantly to prediction of work functioning after clinical variables were entered. Stressful life events were not associated with work adjustment. Overall, presence of a good quality supportive relationship was the strongest unique predictor of work. The results highlight the need to study functional outcomes in patients, especially because they appear only modestly associated with clinical status.

Relationship between depression and substance use disorders in adolescent women during the transition to adulthood

OBJECTIVES

To examine the continuity of substance use disorder (SUD) in adolescent women during the transition to adulthood and to assess psychosocial functioning associated with SUD. Furthermore, to examine concurrent and longitudinal relationships' between major depressive disorder (MDD) and SUD during this developmental transition.

METHOD

One hundred fifty-five women, aged 17 to 19 years, were recruited from 3 high schools and were followed annually for 5 years. Comprehensive diagnostic and psychosocial assessments were performed with standardized instruments. The primary outcome measures included MDD and SUD during follow-up in those with and without a prior history of MDD or SUD, and psychosocial functioning associated with SUD.

RESULTS

The 5-year incidence of SUD was 9.6% and, by the end of follow-up, 18.7% had a lifetime episode. Prior SUD significantly increased the risk for SUD diagnosis during the study. Co-occurrence of MDD and SUD was high during adolescent and early adult years, with episodes of both disorders occurring in close temporal proximity. SUD also predicted MDD over time, but the reverse was not true. After controlling for the effects of MDD on social adjustment, SUD was associated with significant impairment in school functioning.

CONCLUSIONS

These results suggest that the risk for new onset and recurrence of SUD is high during the developmental transition to adulthood. SUD during this developmental period is associated with significant school-related problems. The findings also suggest that SUD and MDD frequently co-occur during the post-high school transition in women. Given the significant psychosocial dysfunction associated with these illnesses, early detection of these problems and effective intervention are crucial.

Continuity of depression during the transition to adulthood: a 5-year longitudinal study of young women

OBJECTIVE

To characterize the clinical course and psychosocial correlates of unipolar depression in late adolescent women and to examine the continuity in affective disturbance from adolescence to early adulthood during the post-high school transition.

METHOD

One hundred fifty-five women aged 17 or 18 years were recruited from 3 local public high schools and were followed at yearly intervals for 5 years for clinical and psychosocial outcomes.

RESULTS

The 5-year incidence of first major depressive episode was 36.9%, and overall, 47% of the women had one or more episodes of major depression. Risk for recurrence was substantial, and those with onsets prior to the study were more likely to have depressive episodes during the post-high school period. The presence of nonaffective disorder also increased the risk for depression. Young women with major depression during the post-high school transition had more negative functional outcomes in school and intimate romantic relationships.

CONCLUSIONS

These results suggest that there is substantial continuity in affective disturbance from adolescence to adulthood. The risk for both new onset of depression and recurrence is remarkably high during late adolescence, and the risk continues throughout early adult years, accompanied by notable interpersonal dysfunction.

Age and gender as determinants of stress exposure, generation, and reactions in youngsters: a transactional perspective

The present study used a contextual and transactional approach to examine age and gender differences in the experience and consequences of life stress in clinic-referred preadolescents and adolescents. Eighty-eight youngsters and their parents completed the Child Episodic Life Stress Interview, a detailed semistructured interview assessing the occurrence of stressful events in multiple life domains. Interviews were coded using a contextual threat rating method to determine event stressfulness and dependence. Youngsters also completed the Children's Depression Inventory and the Revised Child Manifest Anxiety Scale to assess self-reported symptoms of depression and anxiety. Consistent with predictions, age- and gender-related patterns of life stress varied across the type and context of stressors. Most notably, adolescent girls experienced the highest levels of interpersonal stress, especially stress and conflict that they generated within parent-child and peer relationships. Preadolescent girls experienced the highest levels of independent stress and conflict in the family context. Adolescent boys experienced the highest levels of noninterpersonal stress associated with self-generated events. Girls demonstrated particular vulnerability to depressive responses to dependent stress. The results build on and extend previous theory and research on age and gender differences in close relationships and stress, and illustrate the value of more refined conceptual models and more sophisticated methodologies in child life stress research.

Depression and Axis II symptomatology in an adolescent community sample: concurrent and longitudinal associations

The relationship between personality pathology and depression has been the focus of increasing attention, but few investigators have examined this issue prospectively or in adolescent community samples. The present study used both self report and interviewer assessments of personality disorder symptomatology and depression in a sample of 155 late adolescent women followed over three years. Personality pathology cluster and total scores demonstrated moderate to fairly high degrees of stability, indicating endurance of these traits in late adolescence. As predicted, Axis II symptoms were associated with concurrent depressive symptomatology. Overall, self-reported personality disorder symptoms, as well as those specifically in Clusters A and B, predicted interviewer-rated depression over two years beyond the contribution of initial depression, indicating that subclinical Axis II symptoms are a risk factor for subsequent depressive symptomatology.

The context of depression in clinic-referred youth: neglected areas in treatment

OBJECTIVE

To review the empirical, methodological, and conceptual limitations of psychotherapy and pharmacotherapy for childhood and adolescent depression and to present descriptive data on key characteristics of a depressed sample to illustrate gaps in treatment.

METHOD

Interview-based assessment of psychiatric features and psychosocial functioning, family psychopathology and marital adjustment, and child and parent stressful life events was performed in a sample of 43 depressed youngsters seeking outpatient treatment.

RESULTS

The empirical and conceptual review indicated that treatments based on downward extensions of adult procedures are limited in number and success. Also, the treatments generally neglect the following characteristics revealed in the descriptive data: depressed youngsters have high rates of recurrent depression and comorbid conditions, impaired academic and social functioning, exposure to high rates of parental psychopathology, parental assortative mating, severe marital dysfunction, and high rates of severe stressors.

CONCLUSIONS

Treatments need to be informed by and address the actual characteristics of depressed youngsters and their environments, which are highly dysfunctional.

Axis II symptomatology, depression, and life stress during the transition from adolescence to adulthood

This study examined 2 models of the relationship between personality disorder symptomatology and depression, incorporating life stress as an intervening variable. In a community sample of late adolescent women, symptoms of Cluster B disorders predicted interpersonal chronic stress and self-generated episodic stress over 2 years, controlling for initial depression. Cluster A symptoms also predicted subsequent chronic interpersonal stress, over initial depression. Cluster C pathology did not predict subsequent stress. Personality disorder symptomatology was also associated with partner-reported relationship dissatisfaction. Support was found for a mediation model whereby women with higher levels of initial personality disturbance in Clusters A and B generated excessive amounts of episodic stress and interpersonal chronic stress in the next 2 years, which, in turn, increased vulnerability for depressive symptoms. A moderation model, whereby the presence of greater personality disorder symptoms would increase the likelihood of depression in response to stress, was not supported.

Why does attachment style change?

Adult attachment research has proceeded on the assumption that attachment style is relatively stable and affects future functioning. However, researchers have become interested in attachment instability and predictors of attachment style change. In this article, 2 conceptualizations of attachment style change were examined: Attachment style change is a reaction to current circumstances, and attachment style change is an individual difference in susceptibility to change that is associated with stable vulnerability factors. A total of 155 women were assessed after high school graduation, and 6 months and 2 years later. Results primarily supported the conceptualization of attachment style change as an individual difference. Specifically, some women may be prone to attachment fluctuations because of adverse earlier experiences, and women who show attachment fluctuations are similar to women with stably insecure attachments.

Gender differences in depressive symptoms in adolescence: comparison of national samples of clinically referred and nonreferred youths

Gender differences in depressed mood, a syndrome of mixed anxiety-depression, and an analogue of major depressive disorder were compared in parents' and adolescents' reports in 2 large, demographically matched national samples of clinically referred and nonreferred adolescents. Referral status accounted for the greatest share of the variance in these problems. Gender differences were moderate in size and consistent in referred youths, with referred girls scoring higher than referred boys on all measures, whereas gender differences in nonreferred adolescents were either nonsignificant or small in magnitude. Gender differences were also larger in magnitude in adolescents' self-reports than in parents' reports. The interaction of age and gender was nonsignificant in all analyses. Implications for understanding the extent of gender differences in adolescents' depressive symptoms are highlighted.

Predictors of the generation of episodic stress: a longitudinal study of late adolescent women

The effects of depression and Axis I comorbidity on subsequent self-generated life stress were examined in a longitudinal sample of 134 late adolescent women. The results indicated that specific forms of psychopathology constitute a risk factor for future self-generated episodic stress, even when controlling for prior chronic stress. Comorbid depression had a particularly salient effect in the prediction of stress related to interpersonal conflicts. The effects of family psychopathology and sociotropy were mediated through participant psychiatric status, whereas autonomy made an independent contribution to the prediction of episodic stress. These results support C. Hammen's (1991b) stress generation model in a community sample, demonstrating how individuals with depression play a role in the creation of stress, and also refine prior work by showing that only the comorbid form of depression is associated with subsequent conflict-related stress.

Stress reactivity in bipolar patients and its relation to prior history of disorder

OBJECTIVE

Two questions were posed: Does stress precipitate episodes of bipolar I disorder, and does sensitivity to stress differ in episodes later in the course of illness compared to early ones?

METHOD

Fifty-two patients with bipolar I disorder were followed longitudinally for up to 2 years; clinical course was monitored, and interview assessments of life events were made every 3 months.

RESULTS

The patients who had episodes of illness during follow-up had experienced significantly more severe stressors and more total stress in the preceding 6 months, and more total stress in the preceding 3 months, than those without episodes. Inconsistent with Post's stress "sensitization" hypothesis, patients with more prior episodes were more likely to have episodes following major stressors, and they relapsed more rapidly.

CONCLUSIONS

Stressors may precipitate episodes of bipolar illness, especially for patients with more prior episodes. Different versions of the stress sensitization model remain to be tested.

Predictors of the generation of episodic stress: a longitudinal study of late adolescent women

The effects of depression and Axis I comorbidity on subsequent self-generated life stress were examined in a longitudinal sample of 134 late adolescent women. The results indicated that specific forms of psychopathology constitute a risk factor for future self-generated episodic stress, even when controlling for prior chronic stress.

A cognitive-interpersonal approach to depressive symptoms in preadolescent children

Cognitive and interpersonal aspects of depressive symptoms were investigated in a community sample of children. Eighty-one 8- to 12-year-olds completed scales assessing cognitive representations of social relationships and symptoms of depression and anxiety. Teachers provided ratings of peer rejection. Children with elevated levels of depressive symptoms displayed increased negativity in their beliefs about self, family, and peers, as well as distinct patterns of interpersonal information processing. Anxiety symptoms did not make a unique contribution beyond depression to negative representations of family and peers; in contrast, symptom-specific profiles of self-representations were found. Structural equation analysis supported a model linking negative interpersonal representations, peer rejection, and depressive symptoms. The findings suggest that future studies may benefit from approaches that incorporate both cognitive and interpersonal variables as predictors of child depression.

The relationship between attachment cognitions and psychological adjustment in late adolescent women

This longitudinal study of 137 female high school seniors investigated the relationship of attachment cognitions, current psychological functioning, and psychological functioning 12 months later. Attachment cognitions, assessed with the Revised Adult Attachment Scale and the Inventory of Parent and Peer Attachment, were significantly associated with current symptomatology. The Revised Adult Attachment Scale, in interaction with initial symptomatology, predicted depression, substance abuse, eating disorders, and personality disorders 12 months later. The Inventory of Parent and Peer Attachment parent subscales predicted eating disorder and personality disorder symptomatology, whereas the peer subscales predicted substance abuse, eating disorder, and personality disorder symptomatology.

Relapse and impairment in bipolar disorder

OBJECTIVE

The purpose of this study was to evaluate the outcome of bipolar disorder in the context of maintenance pharmacotherapy.

METHOD

Eighty-two bipolar outpatients were followed prospectively for a mean of 4.3 years (minimum of 2 years); symptom rating and psychosocial outcome scales were used, and pharmacotherapy was rated on a 5-point scale.

RESULTS

Despite continual maintenance treatment, survival analysis indicated a 5-year risk of relapse into mania or depression of 73%. Of those who relapsed, two-thirds had multiple relapses. Relapse could not be attributed to inadequate medication. Even for those who did not relapse, considerable affective morbidity was observed. A measure of cumulative affective morbidity appeared to be a more sensitive correlate of psychosocial functioning than was the number of relapses. Poor psychosocial outcome paralleled poor syndromal course. Poor psychosocial functioning, especially occupational disruption, predicted a shorter time to relapse. Depressions were most strongly related to social and family dysfunction.

CONCLUSIONS

Even aggressive pharmacological maintenance treatment does not prevent relatively poor outcome in a significant number of bipolar patients.

Poor interpersonal problem solving as a mechanism of stress generation in depression among adolescent women

The authors examined C. Hammen's (1991) model of stress generation in depression and the role of interpersonal problem-solving strategies (IPS) in the stress generation process in a longitudinal sample of 140 young women who entered the study at ages 17-18. Structural equation modeling was used to test a model in which IPS and subsequent interpersonal stress mediated the relationship between initial and later depressive symptoms. Results supported the main prediction of the stress generation model: Interpersonal stress mediated the relationship between initial and later depressive symptoms. In addition, IPS predicted interpersonal stress. However, no association was found between depressive symptoms and IPS. An alternative model in which IPS moderated the relationship between stress and depressive symptoms was tested; it was not supported.

Cognitive representations of self, family, and peers in school-age children: links with social competence and sociometric status

Attachment and social-cognitive theories of interpersonal relations have underscored the integral role that internalized cognitive representations may play as mediators of the link between family and peer relationships. 3 predictions consistent with this conceptualization received support in the present study of 161 7-12-year-old school children. In Part 1 of the study, significant connections were found among different components of cognitive representations, including social perceptions, interpersonal expectancies, and schematic organization and processing of social information. Moreover, generalization was found among children's representations across 3 interpersonal domains--that is, family, peer, and self. In Part 2, negative representations of self and others were found to be associated with increased social impairment, including dysfunctional social behavior and less positive status in the peer group. Implications of the findings for theories of interpersonal competence and interventions with socially impaired children are discussed.

Correlates of stress reactivity in patients with bipolar disorder

OBJECTIVE

The authors examined individual differences in stress reactivity as well as whether features of the illness itself or psychological characteristics differentiate between patients with bipolar disorder who are highly stress reactive and those who are not.

METHOD

They assessed stressors and bipolar episodes in 58 patients with bipolar disorder followed for at least 1 year.

RESULTS

Not only did stress level predict relapse, so did personality variables such as introversion and obsessionality and their interaction with stress. Number of previous episodes of bipolar illness, however, did not affect stress response.

CONCLUSIONS

These results are not consistent with the view that episodes of bipolar disorder become increasingly independent of stressors after initial episodes. However, psychological traits may affect reactivity to stressors.

Interpersonal functioning and depressive symptoms in childhood: addressing the issues of specificity and comorbidity

Research has supported linkages between depression and social impairment in youngsters, but has often focused on depressive symptoms in isolation. We collected data on depressive, anxiety, and externalizing symptoms in 161 school children. Information about interpersonal competence was gathered from several sources, including children, teachers, and behavioral observations. Depressive symptoms were found to be related to difficulties in multiple areas of competence, including maladaptive social problem-solving styles, conflict-negotiation and affect-regulation deficits, and peer rejection. Comparisons of the relative contributions made by depressive and anxiety symptoms to the prediction of functioning yielded some evidence for a specific relation between depressive symptoms and impairment. Children with cooccurring internalizing and externalizing symptoms generally suffered from the most social dysfunction. If replicated in clinical samples, findings such as these may help to guide intervention efforts with depressed children.

Maternal interaction style in affective disordered, physically ill, and normal women

Affective style (AS) and communication deviance (CD) have been suggested as markers of dysfunctional family environments that may be associated with psychiatric illness. Studies have focused mainly on parental responses during family interactions when an offspring is the identified patient. The present study is unique in examining AS and CD in mothers with unipolar depression, bipolar disorder, or chronic physical illness, and in normal controls. The sample consisted of 64 mothers with children ages 8 to 16. Unipolar mothers were more likely to show negative AS than were any other maternal group. There were no group differences for CD. Chronic stress, few positive life events, and single parenting were associated with AS. CD was associated solely with lower socioeconomic status. Results suggest that dysfunctional interactions are determined not only by maternal psychopathology, but also by an array of contextual factors that are related to the quality of the family environment.

Parenting in homeless families: the double crisis

The same factors that impede a mother's ability to maintain a stable residence are likely to impair her capacity to nurture children. This double crisis of homelessness and child rearing confronts caregivers with a special set of ethical and practical dilemmas. Psychosocial characteristics of homeless mothers and children are reviewed, and the need to support these mothers is underscored.

Stress exposure and stress generation in children of depressed mothers

Two hypotheses were tested: (a) One mechanism contributing to the high rate of disorder in children of women with affective disorders is elevated exposure to stressful events and conditions and (b) the children of depressed women, particularly women with unipolar depression, contribute to event occurrence because of increased interpersonal conflict. Life stress interview assessments were made at 6-month intervals for 3 years on 53 children of unipolar, bipolar, medically ill, and normal women. Both hypotheses were confirmed. Transactional models of risk and further studies of the interpersonal functioning of children at risk for depression are needed.

Communication styles of children of mothers with affective disorders, chronic medical illness, and normal controls: a contextual perspective

Research has demonstrated impaired parent-child relationships in families with affective disorders. The present study examines the association of children's interactional style during a direct conflict-solving task to both the mother's interactional style and the child's diagnostic status. The sample includes 63 children, ages 8 to 16, of mothers with affective disorders, chronic medical illness, and normal controls. Children's dominant coping style profile (CS) (autonomous, neutral, or critical) was related to their mother's affective style (AS) (benign or negative). Affective disorder in the child at 6-month followup was associated with a critical CS profile at intake, while the child's nonaffective symptomatology was unrelated to CS. Findings indicate that children's affective disturbance is linked to interpersonal deficits in affectively charged situations. Results suggest that the child's CS is more strongly predicted by maternal AS than by either the child's or the mother's diagnostic status.

Psychiatric history and stress: predictors of severity of unipolar depression

Unipolar depression is frequently a recurrent or chronic disorder. In studies on predicting its course, outcomes are typically linked to either psychiatric features or stressful life events. In order to integrate the 2 approaches, 51 unipolar patients were assessed periodically over at least 1 year for symptoms, stressful events, and chronic stressors. It was hypothesized that adverse family history and early age of onset impair role functioning and coping capabilities, thereby contributing to stressful circumstances that predict severity of depressive reactions. Results of causal modeling analyses supported a model in which background factors were associated with severity of depressive outcomes as mediated by their effects on stress variables. Such a model implicates the self-perpetuating nature of clinical depression, both for the individual and across generations.

Generation of stress in the course of unipolar depression

The effect of stressful events on depression has been amply demonstrated, but the opposite relation is also important. I examined event occurrence over 1 year in 14 women with unipolar depression who were compared with demographically matched groups of women with bipolar disorder (n = 11), chronic medical illness (n = 13), or no illness or disorder (n = 22). Interview assessments of life events, severity, and independence of occurrence confirmed the hypothesis that unipolar women were exposed to more stress than the normal women, had significantly more interpersonal event stress than all others, and tended to have more dependent events than the others. The implication is that unipolar women by their symptoms, behaviors, characteristics, and social context generate stressful conditions, primarily interpersonal, that have the potential for contributing to the cycle of symptoms and stress that create chronic or intermittent depression.
